Warning

As with all machines, there is a certain amount of hazard involved with the use of this planer. Use the

machine with the respect and caution demanded where safety precautions are concerned. When normal

safety precautions are overlooked or ignored, personal injury to the operator can result.

Read, understand and follow the safety and operating instructions found in this manual. Know the

limitations and hazards associated with this machine.

Electrical grounding. Make certain that the machine frame is electrically grounded and that a ground

lead is included in the incoming electrical service. In cases where a cord and plug are used, make certain

that the grounding plug connects to a suitable ground. Follow the grounding procedure indicated in the

National Electrical Code. If connected to a circuit protected by fuses, use time delay fuse marked “D”.

Eye safety. Wear an approved safety shield, goggles, or glasses to protect eyes. (NOTE: Common

eyeglasses are only impact-resistant, they are not safety glasses.)

Personal protection. Before operating the machine, remove tie, rings, watch and other jewelry and roll

up sleeves above the elbows. Remove all loose outer clothing and confine long hair. Protective type

footwear should be used. Where the noise exceeds the level of exposure allowed in Section 1910.95 of

the OSHA Regulations, use hearing protective devices. Do not wear gloves.

Guards. Keep the machine guards in place for every operation for which they can be used. If any guards

are removed for maintenance, DO NOT OPERATE the machine until the guards are reinstalled.

Placement. Place machine so that potential kickback area is not in line with aisles, doorways, wash

stations, or other work areas. Do not expose machine to rain or use in damp locations.

Work area. Keep the floor around the machine clean and free of scrap material, saw dust, oil and other

liquids to minimize the danger of tripping or slipping. Be sure the table is free of all scrap, foreign material

and tools before starting to cut. Make certain the work area is well lighted and that a proper exhaust

system is used to minimize dust. It is recommended that anti-skid floor strips are used on the floor area

where the operator normally stands and that each machine’s work area be marked off. Provide adequate

work space around the machine.

Avoid accidental starting: Make certain motor switch is in off position before connecting power to the

machine.

Operator position. Maintain a balanced stance and keep your body under control at all times. Stand to

one side out of line with the table and make sure no one else is standing in line with the table.

Housekeeping. Before turning on machine, remove all extra equipment such as keys, wrenches, scrap,

and cleaning rags away from the machine

Careless acts. Give the work you are doing your undivided attention. Looking around, carrying on a

conversation, and “horseplay” are careless acts that can result in serious injury.

Disconnect machine before performing any service or maintenance or when changing blades. A

machine under repair should be RED TAGGED to show it should not be used until the maintenance is

complete.

Maintain tools in top condition. Keep tools sharp and clean for safe and best performance. Dull tools

increase noise levels and can cause kickbacks and glazed surfaces. Check the condition and adjustment

of the tools before making any cuts. Follow the sharpening instructions on knife grinding and jointing,

installing and adjustments.

5

Hand safety. Keep hands outside the machine. NEVER reach under the guards to try to clear stock that

stops feeding. Do not clear chips and sawdust with hands; use a brush. Do not have any part of the

hands under that part of the board that is over the table when starting a cut; the infeed roll will engage the

board and force it down against the table causing a pinching action. Do not operate machine while the

gear cover is open.

Cutterhead rotation: Be sure cutterhead rotates under power in a counterclockwise direction when

viewed from the main drive motor side.

Material condition: Do not plane boards with loose knots or with nails or any foreign material on its

surface. Knife impact on these objects can cause the knives to be pulled out and cause them to shatter

against the chipbreaker or pressure bar. Twisted, warped, or in wind stock should first be jointed on one

surface before attempting to plane a parallel surface on the planer. Serious stock flaws cannot be

removed by use of a planer alone.

Machine adjustments: Make all machine adjustments with power off except feed rate.

Avoid kickback: To avoid kickbacks, use this machine for single board surfacing only. Never make cuts

deeper than 1/8 inch (3mm).

Job completion. If the operator leaves the machine area for any reason, the planer should be turned

"off" and the cutterhead should come to a complete stop before his departure. In addition, if the operation

is complete, he should clean the planer and the work area. Never clean the planer with power "on" and

never use the hands to clear sawdust and debris; use a brush.

Replacement parts. Use only Powermatic or factory authorized replacement parts and accessories;

otherwise the warranty and guarantee is null and void.

Misuse. Do not use this planer for other than its intended use. If used for other purposes, Powermatic

disclaims any real or implied warranty and holds itself harmless for any injury or damage which may result

from that use.

If you are not thoroughly familiar with the operation of planers, obtain advice from your supervisor,

instructor or other qualified person.

Drugs, alcohol, medication. Do not operate this machine while under the influence of drugs, alcohol, or

any medication.

Health hazards. Some dust created by power sanding, sawing, grinding, drilling and other construction

activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some

examples of these chemicals are:

* Lead from lead-based paint.

* Crystalline silica from bricks and cement and other masonry products.

* Arsenic and chromium from chemically-treated lumber.

Your risk from these exposures varies, depending on how often you do this type of work. To reduce your

exposure to these chemicals, work in a well-ventilated area, and work with approved safety equipment,

such as those dust masks that are specifically designed to filter out microscopic particles.

Familiarize yourself with the following safety notices used in this manual:

This means that if precautions are not heeded, it may result in minor injury and/or

possible machine damage.

This means that if precautions are not heeded, it may result in serious injury or possibly

even death.

Installation and Assembly

Tools required for assembly:

Forklift or hoist with slings

10-12,12-14mm open-end wrenches (provided)

4 and 5mm hex wrenches (provided)

16mm open-end wrench

Remove the screws holding the planer to the

pallet and use a forklift or hoist to lift the planer

off the pallet. Forks and straps should always be

placed under the four lifting handles when lifting

this machine (Figure 5). The lifting handles can

be pushed back in when not in use.

The planer should be operated in a well-lit area

with good ventilation. It can be rolled on its

casters to the desired location. Press the foot

pedal (Figure 6) to prevent movement during

operation or adjustments.

Exposed surfaces, such as tables, rollers,

cutterhead, etc., have been given a protective

coating at the factory. This should be removed

with a soft cloth moistened with a good

commercial solvent. Do not use acetone,

gasoline, lacquer thinner, or other solvents with

a low flash point. Do not use an abrasive pad

because it may scratch the polished cast iron

surfaces.

Use care when cleaning

around the cutterhead area – knives are

extremely sharp!

Handwheel

1. Place the key into the slot on the shaft

(Figure 7), and mount the handwheel to the

shaft, making sure it is oriented so it slips

over the key.

2. Peel off the backing of the directional label,

and attach it to the center of the handwheel.

Place flat washer and hex nut on shaft and

tighten with 16mm wrench.

3. Mount the handle in the threaded hole in the

handwheel, and tighten with a 12mm wrench

placed over the flat on the handle.

Starter Box

Mount the controls as shown in Figure 8, with

the two socket head cap screws which you’ll find

mounted to the head casting. Use a 5mm hex

wrench.

Figure 5

Figure 6

Figure 7

Figure 8

9

Extension Tables

1. Mount a cast iron table to the edge of the

main table with three M8 x 25 hex cap

screws (Figure 9) using a 12mm wrench. Do

not fully tighten yet.

2. The extension table must be leveled with the

main table. Place a straight edge (such as a

jointed board) across the extension table

and the main table.

NOTE: The straight edge should not lie over

the raised table rollers, as this would distort

the leveling process. Either place the

straight edge just short of the table rollers, or

lower the table rollers completely into the

table (see page 11) while mounting the

extension tables.

3. Insert three socket set screws with a 4mm

hex wrench, and screw them in or out as

needed until tables are level.

4. Securely tighten the hex cap screws.

5. Mount the second extension table to the

opposite side of the planer table, using the

same procedure.

Dust Hood

Mount the dust hood to the rear of the head

casting with three M6 x 12 socket head cap

screws with lock washers, and three M5 x 10

hex cap screws with flat washers. See Figure

10.

It is recommended that you use a dust collection

system with this planer. If you are not using a

dust collection system, do not attach the dust

hood to the planer, as the accumulation of dust

inside the hood may create a safety hazard, or

eventually cause jamming of the rollers.

Electrical Connections

Electrical connections must

be made by a qualified electrician in

compliance with all relevant codes. The

machine must be properly grounded to help

prevent electrical shock and possible fatal

injury.

A power plug is not provided with the 15S or

15HH planers. You may either connect a 230

volt plug or "hard-wire" the machine directly to

your electrical panel provided there is a

disconnect near the machine. Consult electrical

schematic on page 38 for further clarification of

wiring setup.

Figure 9

Figure 10

It is recommended that the 15S or 15HH Planer

be connected to a dedicated, minimum 30 amp

circuit with a 30 amp circuit breaker or time

delay fuse. Local codes take precedence over

recommendations.

10

This machine must be grounded. Grounding

provides a path of least resistance to help divert

current away from the operator in case of

electrical malfunction.

Make sure the voltage of your power supply

matches the specifications on the motor plate of

the machine.

Extension Cords

The use of an extension cord is not

recommended for this machine, but if one is

necessary make sure the cord rating is suitable

for the amperage listed on the machine's motor

plate. An undersized cord will cause a drop in

line voltage resulting in loss of power and

overheating.

The chart in Figure 11 shows the correct size

cord to use based on cord length and motor

plate amp rating. If in doubt, use the next

heavier gauge. The smaller the gauge number

the heavier the cord.

Adjustments

Tools required for assembly:

10, 12 and 17mm open-end wrenches

3, 5 and 6mm hex wrenches

0.020” (0.5mm) feeler gauge

straight edge

gauge block

cross-point screwdriver

Disconnect machine from

power source before making any

adjustments (except feed rate).

Belt Tension

Inspect the tension of the belts frequently during

the first few times you use the planer. Belts often

stretch during this trial period. If they require

tightening, proceed as follows:

1. Remove the belt guard and the rear panel.

2. Loosen the bottom nut on the motor

adjustment screw (Figure 12) with a 17mm

wrench.

3. Turn the top nut on the adjustment screw to

lower the motor plate, which will increase

the belt tension.

4. Proper tension is achieved when there is

slight deflection in the belt midway between

the pulleys, using moderate finger pressure.

5. Tighten the bottom nut on the adjustment

screw (Figure 12).

Pulley Alignment

The pulleys should be in line for proper belt

operation.

1. Remove the belt guard and place a straight

edge against the faces of both pulleys

(Figure 13).

2. If the straight edge does not lie flat on both

pulley faces, open the rear panel and loosen

the four hex nuts on the motor plate (see

Figure 12) with a 12mm wrench.

3. Nudge the motor left or right until the pulleys

are in alignment.

4. Tighten hex nuts and replace covers.

Table Rollers

Your planer is supplied with two table rollers

(Figure 14) which turn as the stock is fed into the

machine, thus reducing friction. It is not possible

to give exact dimensions on the proper height

setting of the table rollers because each type of

wood behaves differently. As a general rule,

however, when planing rough stock the table

rollers should be set at high position. When

planing smooth stock the rollers should be set at

low position.

NOTE: When raising the roller higher above the

table, the range is from zero to 0.006" (Figure

15).

Figure 15

The table rollers are factory set for average

planing and are parallel to the table surface. If

you desire to adjust the table rollers higher or

lower, proceed as follows:

1. Disconnect machine from power source.

2. Lay a straight edge across both rollers.

3. On one side of table, loosen set screws

(Figure 16) with 3mm hex wrench, and turn

eccentric shafts to raise or lower the rollers.

4. When proper height is achieved, tighten set

screws.

5. Adjust the rollers from the opposite side of

the table in the same manner.

Figure 13

Figure 14

Figure 16

12

IMPORTANT: Be sure that the height of front

and rear rollers are the same. And the table

rollers must always be set parallel to the table.

Cutterhead

Although your planer was carefully adjusted at

the factory, it should be checked before being

put into operation. Any inaccuracies due to

rough handling in transit can be corrected by

following the directions in this manual.

To check the adjustments you will need feeler

gauges, and a dial gauge or home-made gauge

block made of hardwood. This gauge block can

be made by following the dimensions shown in

Figure 17.

Replacing Knives (Model 15S only)

Use caution and proceed

slowly when working with and around the

knives – they are extremely sharp!

When dull knives are replaced, care must be

exercised in setting the new knives into the

cutterhead. There is a certain procedure to

follow which will ensure a proper setting of

knives on the 15S Planer. Proceed as follows:

1. Disconnect machine from power source.

2. Remove the dust hood and the top cover.

Remove the chip deflector (Figure 28 shows

the chip deflector). Remove the belt guard

so you can rotate the cutterhead using the

pulley.

3. Remove the gib screws with the T-handle

hex wrench, as shown in Figure 18, and

remove each gib one at a time.

4. Carefully remove the knife, and clean the

cutterhead slot of any dust or debris.

5. Place the new knife into the cutterhead slot.

6. IMPORTANT: As you proceed with knife

installation, make sure the wings on both

ends of each hole (see Figure 18) are

completely inserted into the groove in the

cutterhead. Failure to do this may result in

knife breakage during operation.

7. There are a total of three short gibs and

twelve long gibs on the cutterhead. It is not

important whether long or short gib is used

in any particular location along the knife. Of

course, each knife must use one short gib.

8. Put the first gib in place at the end of the

cutterhead. Use the knife adjustment pins

shown in Figure 19. The adjustment pins fit

down through the smaller holes in the gib,

knife, and cutterhead, helping to align them.

Figure 17

Figure 18 – Model 15S only

Figure 19 – Model 15S only

13

(You can also use any 3mm diameter tool,

such as a hex wrench or drill bit for this

purpose.)

9. Insert the screws for the first gib, turning

them with the T-handle wrench. Do not fully

tighten the screws; make them only snug

enough to hold the knife in the groove.

10. Put the next gib in place, and repeat the

process. See Figure 19. Use the adjustment

pins and make sure the wings of the knife

are completely in the cutterhead groove.

Continue sequentially from one end of the

cutterhead to the other end. Again, only

make the screws snug enough to hold the

knife in the groove.

11. When all gibs are loosely installed for one

knife, rotate the cutterhead and repeat the

process for each of the remaining two

knives, working from one end to the other.

12. Now fully tighten all gib screws on one knife.

Do this in sequential order, beginning at one

end of the knife and working your way

across to the other end, tightening each

screw in turn.

13. Tighten all gib screws on the other two

knives in the same fashion, until all gib

screws on the cutterhead are firmly

tightened.

(NOTE: The purpose of this incremental

tightening process is to prevent any slight

deflection or warpage of the cutterhead, and

to ensure that the knife is completely seated

into the groove.)

After installing knives, check

again carefully. Make certain all gib screws

are tightened securely. Failure to heed may

result in personal injury.

14. Re-install chip deflector (see “Chip

Deflector”, page 17). Re-install cover with

the four washer head screws, and re-install

belt guard.

Replacing or Rotating Knife Inserts

(Model 15HH only)

The knife inserts on the model 15HH are four-

sided. When dull, simply remove each insert,

rotate it 90° for a fresh edge, and re-install it.

Use the provided driver with the socket adaptor

to remove the knife insert screw. See Figure 20.

NOTE: A T25 adaptor or driver can round out

the screw head. Always use a T25-Plus driver

or adaptor.

Figure 20 – Model 15HH only

It is advisable to rotate all inserts at the same

time to maintain consistent cutting. However, if

one or more knife inserts develops a nick, rotate

only those inserts that are affected.

Each knife insert has an etched reference mark

so you can keep track of the rotations.

IMPORTANT: When removing or rotating

inserts, clean saw dust from the screw, the

insert, and the cutterhead platform. Dust

accumulation between these elements can

prevent the insert from seating properly, and

may affect the quality of the cut.

To install new knife inserts:

1. Before installing each screw, lightly coat the

screw threads with machine oil and wipe off

any excess.

2. Position knife insert and move it back and

forth to verify there are no burrs or dirt.

3. Hold insert away from the back of the seat

(pull slightly toward yourself if facing the

cutting edge) and allow the screw to pull

insert into position. Note: A slight offset

between screw hole and hole in knife insert

is normal. Do not position insert directly over

screw hole, as it could ride up on the back of

the seat and potentially cause cracking of

the tip.

4. Securely tighten each screw which holds the

knife inserts before operating the planer.

IMPORTANT: Maximum torque for tightening

the screws is 45 to 55 inch pounds (3.75 to 4.6

foot pounds).

Make sure all knife insert

screws are tightened securely. Loose inserts

can be propelled at high speed from a

rotating cutterhead, causing injury.

Work Table Parallel to Cutterhead

The work table is set parallel to the cutterhead at

the factory and no further adjustment should be

necessary. If your machine is planing a taper,

first check to see if the knives are set properly in

the cutterhead. Then check to see if the work

table is set parallel to the cutterhead. Proceed

as follows:

1. Disconnect machine from power source.

2. Place the gauge block (Figure 21) on the

work table directly under the edge of a knife

as shown. Make slight contact by gently

raising table.

3. Move the gauge block to the opposite end of

the work table. NOTE: Distance from the

work table to edge of knife should be the

same.

4. If the work table is not parallel to the

cutterhead, perform the adjustment

procedure as follows.

5. Remove bolts holding the planer to the

stand. Carefully tilt planer on its side to

expose underside of base (Figure 22).

6. Remove bolt (A, Figure 22) and loosen bolt

(B, Figure 22) which will allow you to move

the idler sprocket assembly (C, Figure 22)

far enough to release tension on the chain.

7. Remove the chain from the particular

sprocket on the corner of the base that you

need to adjust.

8. Turn the sprocket by hand to bring that

corner into adjustment with the other three

corners. NOTE: Turning sprocket clockwise

will increase the distance between the

working table and the head casting;

counterclockwise will decrease the distance.

This adjustment is very sensitive and it

should not be necessary to turn the sprocket

more than one or two teeth.

9. When adjustments are correct, replace

chain around corner sprocket, slide idler

sprocket (C, Figure 22) back to re-tension

chain, tighten bolt (B, Figure 22) and insert

and tighten bolt (A, Figure 22).

Anti-Kickback Fingers

The anti-kickback fingers (A, Figure 23) are an

important safety feature, as they help prevent

kickback of stock. They operate by gravity and

should be inspected frequently to make sure

they are free of gum and pitch, so that they

move independently and operate correctly.

Infeed and Outfeed Roller Spring

Tension

The infeed roller (B, Figure 23) and outfeed

roller (E, Figure 23) are those parts of your

planer that feed the stock while it is being

planed. The infeed roller and the outfeed roller

are under spring tension and this tension must

be sufficient to feed the stock uniformly through

the planer without slipping but should not be so

tight that it causes damage to the board. The

tension should be equal at both ends of each

roller.

To adjust the spring tension of the infeed and

outfeed rollers, turn screws (Figure 24) with a

hex wrench. Turn screws on both ends of

infeed/outfeed rollers in the same manner.

Height of Infeed Roller, Chipbreaker

and Outfeed Roller

The infeed roller, chipbreaker and outfeed roller

are adjusted at the factory. The height

relationship between these items and the

cutterhead is crucial for accurate and safe

planing. The infeed roller, chipbreaker, and

outfeed roller should each be set at 0.02"

(0.5mm) below the cutting circle. See Figure 25.

If any adjustments are necessary for the infeed

roller, chipbreaker, or outfeed roller, they should

be done carefully. Use the following steps as an

example of procedure.

NOTE: This procedure uses a home-made

gauge block and feeler gauges, which should be

sufficient for most planer operations. If extra

precise measurements are desired, use a dial

indicator device.

Figure 24

Figure 25

16

Outfeed Roller Height

1. Disconnect machine from power source.

2. Make sure the knives are set properly as

previously explained under "Knife

Adjustment."

3. Place the gauge block (F, Figure 26) on the

table directly beneath the cutterhead (D,

Figure 26).

4. Using a 0.020" (0.5mm) feeler gauge (G,

Figure 26) placed on top of the gauge block,

raise the work table until the knife just

touches the feeler gauge when the knife is

at its lowest point. Do not move the work

table any further until the outfeed roller is

adjusted.

5. Remove the feeler gauge and move the

gauge block (F, Figure 27) under one end of

the outfeed roller. The bottom of the outfeed

roller should just touch the top of the gauge

block. If an adjustment to the outfeed roller

is necessary, loosen the lock nut (J, Figure

27) and turn screw (H, Figure 27) until the

outfeed roller just touches the gauge block.

Then tighten lock nut (J, Figure 27).

6. Check and adjust the opposite end of the

outfeed roller in the same manner.

Infeed Roller Height

Use the exact same procedure for checking the

infeed roller as you did for the outfeed roller.

Use the .02" (0.5mm) feeler gauge atop the

gauge block. If adjustment is necessary, use the

lock nut and screw on each end of the infeed

roller.

Chipbreaker Height

The chipbreaker breaks off the larger chips

before the stock reaches the cutterhead. Use

the gauge block and a .02" (0.5mm) feeler

gauge to check the height of the chipbreaker,

following the same procedure as above. If

adjustment is needed:

1. Remove top cover.

2. Loosen the lock nuts (A, Figure 28) at both

ends of the chipbreaker, and turn the set

screws to raise or lower the chipbreaker as

needed. The set screws should be turned

the same amount.

3. When the chipbreaker contacts the gauge

block, tighten both lock nuts (A, Figure 28).

Figure 26

Figure 27

Figure 28

17

Chip Deflector

The chip deflector (B, Fig. 28) keeps wood chips

from falling into the outfeed roller. The deflector

should be set approximately 1/16" to 1/8” from

the tip of the knives. Make sure the deflector is

oriented so the bevel on its front edge matches

the shape of the cutterhead.

Feed Speed Control

Your machine is equipped with a spiral, serrated

infeed roller and a solid steel outfeed roller.

When the feed rollers are engaged, they turn to

feed the stock. The feed rollers slow

automatically when the machine is under heavy

load for best planing in all conditions. The feed

rollers are driven by chains and sprockets (see

Figure 29) which take power directly from the

cutterhead through the oil bath gear box. The

drive chain does not need tensioning, as a

tension device (Figure 29) maintains proper

tension at all times.

To gain access to the chain and sprockets:

1. Remove the handwheel from the machine.

2. Remove the socket head cap screw from the

center of the cover, and remove the left

triangular back plate. See Figure 30.

3. Pull the cover off the machine.

Always re-install cover over

the chain and sprockets before operating

planer.

The gear box has two feed speeds. These are

set by pulling out or pushing in the shift lever

(Figure 31). Always change feed speed while

the machine is running. A label showing the

lever positions is affixed just above the lever. It

is also shown in Figure 32.

Do not attempt to change

feed speed while stock is passing through

the machine. Damage to the gearbox may

result.

Stock Return Rollers

The two rollers on top the machine serve as a

convenient rest for stock. They save time and

motion for the operator as the stock is returned

to the infeed side.

Depth of Cut

The cutting depth scale is a combination

inch/metric scale (Figure 33), with a cutting

range from 0 to 6" (152.4mm). A manual scale is

mounted directly to the front column. The model

15S planer also features a digital scale for

easier, more precise depth readings.

Figure 33

The distance of upward or downward movement

is controlled by the handwheel (Figure 33).

Before moving the table up or down, loosen the

locking handles (Figure 33). After obtaining

proper table position, tighten the locking

handles.

Maximum depth of cut is 3/16". A limiter (Figure

33) on the front of the head casting limits the

depth of cut on full width planing under 1/8".

The digital scale should be calibrated before

operating the planer. Refer to page 21.

Maintenance

Disconnect machine from

power source before performing any

maintenance.

Periodic or regular inspections are required to

ensure that the machine is in proper adjustment,

that all screws are tight, that belts are in good

condition, that dust has not accumulated in the

electrical enclosures, and that there are no worn

or loose electrical connections.

Buildup of sawdust and other debris can cause

your machine to plane inaccurately. Periodic

cleaning is not only recommended but

mandatory for accurate planing.

Close-fitting parts, such as the cutterhead slot

and gibs, should be cleaned with a cloth or

brush and non-flammable solvent, and freed

from clinging foreign matter.

Remove resin and other accumulations from

feed rollers and table with a soft rag and non-

flammable solvent.

Periodically check all the chains for proper

tension and adjust accordingly if required.

The table should be kept clean and free of rust.

Some users prefer a paste wax on exposed

steel and cast iron surfaces. The wax provides a

layer of protection as well as reducing friction

between lumber and the table, making cuts

faster and smoother. Avoid any wax that

contains silicone or other synthetic ingredients.

These materials can find their way into lumber

and can make staining and finishing difficult.

Another option is talcum powder applied with a

blackboard eraser rubbed in vigorously once a

week; this will fill casting pores and form a

moisture barrier. This method provides a table

top that is slick and allows rust rings to be easily

wiped from the surface. Important also is the fact

that talcum powder will not stain wood or mar

finishes as some wax pickup does.

Lubrication

The bearings on the cutterhead are factory

lubricated and sealed for life – no lubrication is

required.

Gearbox Lubricant

The lubricant in the gear box must be replaced

every 2,500 hours. Multi-purpose gear box

lubricant will be suitable.

To replace the lubricant:

1. Remove the drain plug (A, Figure 34) with a

14mm wrench, and remove filler cap (B-

Figure 33). Drain dirty oil thoroughly.

2. Insert and tighten the drain plug (A, Figure

34).

3. Fill with clean lubricant through hole (B,

Figure 34).

4. Install and tighten filler cap (B, Figure 34).

Functions of the Digital

Scale (Model 15S only)

Figure 40 identifies the parts of the digital scale.

The button functions are discussed below,

followed by a section giving practical examples

of how to calibrate your settings, and how these

functions can be used for daily planer

operations.

Before using the device, wipe down the vertical

scale with a dry, soft cloth. Do not use cleaning

solutions. Do not allow any liquids (such as

machine oil) to contact the body of the digital

display. Keep the device clean.

This device uses a 1.55 volt battery cell (SR44).

If it needs replacing (see Troubleshooting on

page 26 to determine this) slide off the battery

cover and insert the battery, with the positive

pole of the battery facing out. NOTE: After

replacing a battery, the digital display setting

defaults to zero and must be recalibrated.

ON/OFF/ZERO – power and zero-setting

Press ON/OFF/ZERO button no longer than 3

seconds to power on.

Press ON/OFF/ZERO button at least 3 seconds

to shut off the digital display.

While in relative mode, press ON/OFF/ZERO

(no longer than 3 seconds) to set current

position as relative zero point.

While in absolute mode, press ON/OFF/ZERO

(no longer than 3 seconds) to set current

position as absolute zero point.

ABS – relative/absolute modes

The device is in absolute mode as soon as

power is turned on, and displays absolute zero.

Moving the planer table up and down begins

absolute measurement. Absolute measurement

is set based upon the distance from cutterhead

to table, and thus represents the thickness of

your board.

Press ABS button (no longer than 3 seconds) to

switch to relative mode. “INC” will appear on the

display. The value shown is in relative mode; it

is an incremental position that can be zeroed at

any point and determines not the thickness of a

board, but how much material will be removed

from a board. Moving the table up and down will

now display relative measurement until you

press ABS again to go back to absolute.

IMPORTANT: Always place the digital display in

relative (“INC”) mode before turning it off. If you

turn it off while in absolute (“ABS”) mode, your

absolute setting will default to zero.

Figure 40

MM/INCH – millimeters/inches

Pressing this button toggles back and forth

between standard and metric, and can be done

at any time without affecting saved settings.

HOLD – maintains data on the display.

Press this button to “freeze” a measurement on

the display; it will remain even if the table is

moved. Press HOLD again and it returns to

normal measurements.

SET – preset a value

Press SET; the indicator will flash “SET”. Press

and hold the SET button and each digit flashes

in turn. When the digit you want flashes, release

the SET button. Press SET button once (no

longer than 1 second) and that digit will increase

by one each time SET is pressed. When

finished, press and hold SET button until

indicator “SET” flashes, then press SET again

(no longer than 1 second). The indicator “SET”

disappears and the value you just input is

displayed on the screen.
