2. Grounded, cord-connected machines intended for

use on a supply circuit having a nominal rating less

than 150 volts:

If the machine is intended for use on a circuit that has an

outlet that looks like the one illustrated in Fig. A, the

machine will have a grounding plug that looks like the plug

illustrated in Fig. A. A temporary adapter, which looks like

the adapter illustrated in Fig. B, may be used to connect

this plug to a matching 2-conductor receptacle as shown

in Fig. B if a properly grounded outlet is not available. The

temporary adapter should be used only until a properly

grounded outlet can be installed by a qualified electrician.

The green-colored rigid ear, lug, and the like, extending

from the adapter must be connected to a permanent

ground such as a properly grounded outlet box. Whenever

the adapter is used, it must be held in place with a metal

screw.

NOTE: In Canada, the use of a temporary adapter is not

permitted by the Canadian Electric Code.

IN ALL CASES, MAKE CERTAIN THE

RECEPTACLE IN QUESTION IS PROPERLY

GROUNDED. IF YOU ARE NOT SURE HAVE A

QUALIFIED ELECTRICIAN CHECK THE RECEPTACLE.

1. All grounded, cord-connected machines:

In the event of a malfunction or breakdown, grounding

provides a path of least resistance for electric current to

reduce the risk of electric shock. This machine is

equipped with an electric cord having an equipment-

grounding conductor and a grounding plug. The plug must

be plugged into a matching outlet that is properly installed

and grounded in accordance with all local codes and

ordinances.

Do not modify the plug provided - if it will not fit the outlet,

have the proper outlet installed by a qualified electrician.

Improper connection of the equipment-grounding

conductor can result in risk of electric shock. The

conductor with insulation having an outer surface that is

green with or without yellow stripes is the equipment-

grounding conductor. If repair or replacement of the

electric cord or plug is necessary, do not connect the

equipment-grounding conductor to a live terminal.

Check with a qualified electrician or service personnel if

the grounding instructions are not completely

understood, or if in doubt as to whether the machine is

properly grounded.

Use only 3-wire extension cords that have 3-prong

grounding type plugs and matching 3-conductor

receptacles that accept the machine’s plug, as shown in

Fig. A.

Repair or replace damaged or worn cord immediately.

POWER CONNECTIONS

MOTOR SPECIFICATIONS

Your machine is wired for 120 volts, 60 HZ alternating current. Before connecting the machine to the power source,

make sure the switch is in the “OFF” position.

GROUNDING INSTRUCTIONS

THIS MACHINE MUST BE GROUNDED WHILE IN USE TO PROTECT THE OPERATOR FROM

ELECTRIC SHOCK.

EXTENSION CORDS

Use proper extension cords. Make sure

your extension cord is in good condition and is a 3-wire

extension cord which has a 3-prong grounding type plug

and matching receptacle which will accept the

machine’s plug. When using an extension cord, be sure

to use one heavy enough to carry the current of the

machine. An undersized cord will cause a drop in line

voltage, resulting in loss of power and overheating. Fig.

D shows the correct gauge to use depending on the

cord length. If in doubt, use the next heavier gauge. The

smaller the gauge number, the heavier the cord.

ADJUSTING SLIDING FIT BETWEEN CUTTINGHEAD ARM AND TRUNNION

After a long period of time, an adjustment of the sliding fit between the cuttinghead arm (B) Fig. 24A and the trunnion

(C) may be necessary. To adjust, tighten the nut (D). This adjustment should not be so tight that it restricts the sliding

movement of the cuttinghead arm (B) or so loose that it affects the accuracy of the cut.

Fig. 24A

ADJUSTING THE TENSION OF CUTTINGHEAD RETURN SPRING

The cuttinghead return spring tension was adjusted at the factory to

make the cuttinghead return to the "up" position after a cut is made.

To adjust the spring tension, turn the adjusting screw (A) Fig. 24A

clockwise to increase or counterclockwise to decrease the spring

tension.

3. To adjust, loosen the bevel lock handle. Loosen the locknut (B) Fig.

21 and turn the adjusting screw (C) with the provided wrenches until

the blade is 90° to the table. Tighten the locknut (B) and the bevel

lock handle..

4. When the blade is 90° to the table, loosen the screw (A) Fig. 22 and

adjust the pointer (B) to line up with the 0° mark on the bevel scale.

Tighten the screw.

5. Loosen the bevel lock handle, and move the cuttinghead all the way

to the left bevel position and tighten the bevel lock handle.

6. Use a square (A) Fig. 23 to see if the blade is at 45° to the table.

7. To adjust, loosen the bevel lock handle. Loosen the locknut (E) Fig.

21 and turn the adjusting screw (F) with the provided wrench, until

the blade is 45° to the table. Tighten the locknut (E) and the bevel

lock handle.

Fig. 21

ADJUSTING LOWER BLADE GUARD

After an extended period of use, the movable lower blade guard (A) Fig. 25 may not operate smoothly when the cuttinghead

is lowered. You can correct this by adjusting the nut (B) until the lower blade guard (A) moves freely

Do not over-tighten the nut.

Fig. 25

TOOL STORAGE

A clip (A) Fig. 26 is provided on the rear of the saw to provide a convenient storage area for the wrench (B).

LOCKING CUTTINGHEAD GUIDE RODS

You can lock the cuttinghead guide rods (C) Fig. 24B to use the saw as a conventional miter saw (chop saw) by

tightening the lock knob (D).

IMPORTANT: Move the cuttinghead to the rear position before locking the guide rods.

ADJUSTING SLIDING FIT BETWEEN GUIDE RODS AND TABLE ASSEMBLY

To adjust the sliding fit between the guide rods (C) Fig. 24B and the table assembly (E):

1. Remove the lock knob (D) and loosen the locknut (F). Use the provided wrenches to hold the locknut (F), and turn

the adjusting nut (G) clockwise to increase or counter-clockwise to decrease the sliding action of the guide rods

(C). This adjustment should not be so tight that it restricts the sliding movement of the cuttinghead arm (B) or so

loose that it affects the accuracy of the cut.

2. After adjusting, use the wrenches to hold the adjusting nut (C) and tighten the locknut (F).

3. Replace the lock knob (D).

NOTE: Periodically, lubricate the guide rods with a light oil or spray lubricant.

1. The downward travel of the saw blade should be limited to

prevent the saw blade from contacting any metal surfaces of

the machine. Make this adjustment by loosening the wing nut

(A) Fig. 24B, and turn the adjusting screw (B) in or out.

2. Lower the blade as far as possible. Rotate the blade by hand

to make certain that the teeth do not contact any metal

surfaces. After adjusting, tighten the wing nut (A) Fig. 24B.

AUXILIARY WOOD FENCE

When performing multiple or repetitive

operations that result in small cut-off pieces (one inch or

less), the saw blade can catch the cut-off pieces and project

them out of the machine or into the blade guard and housing,

causing damage or injury. To limit the risk, mount an auxiliary

wood fence on your saw (Fig. 27).

Holes are provided in the fence to attach an auxiliary fence (A)

Fig. 27. This auxiliary fence is constructed of straight wood

approximately 1/2" thick by 3" high by 20" long. NOTE: The

auxiliary fence (A) is used ONLY with the saw blade in the 0

degree bevel position (90 degrees to the table). When bevel

cutting (blade tilted), remove the auxiliary fence.

Fig. 27

GENERAL CUTTING OPERATIONS

1. Your machine has the capacity to cut standard 2 x 4’s lying flat or on edge, at the 45 degree right and left miter angles (Figs.

A1 and A2).

2. A standard 2 x 6 can be cut in the 90 degree straight cut-off position in one pass (Fig. A3).

3. Cutting a standard 4 x 4 can be accomplished with one pass (Fig. A4).

4. This machine has the capacity to accurately cut crown mouldings and other bevel-type cuts (Fig. A5).

5. Cutting various sizes of plastic pipe is an easy job with this machine (Fig. A6).

MACHINE USE

CUTTING ALUMINUM

Aluminum extrusions such as used for making aluminum screens and storm windows can easily be cut with your

compound miter saw. When cutting aluminum extrusions, or other sections that can be cut with a saw blade and are

within the capacity of the machine, position the material so the blade is cutting through the smallest cross-section (Fig.

28). The wrong way to cut aluminum angles is illustrated in Fig. 29. Be sure to apply a stick wax to the blade before

cutting aluminum stock. This stick wax is available at most industrial mill supply houses. The wax provides proper

lubrication and keeps chips from adhering to the blade.

Never apply lubricant to the blade while the machine is running.

For support when cutting long pieces, construct a work

support extension. Fig. 32 illustrates the miter saw

mounted on two standard 2 x 4’s (A). Fasten the four

mounting legs (two of which are shown at (B) Fig. 32 to

the 2 x 4’s, using four screws (not supplied) through the

four holes in the mounting legs. The length of the 2 x 4’s

(A) can vary, depending on the workpiece.

NOTE: Ensure that the top of the support 2 x 4’s (C)

are level with the miter saw table. This is critical

because the distance from the top of the 2 x 4’s (A) to the

miter saw table varies from saw to saw. In most cases,

standard 2 x 4’s (C) can used. If these are too high, cut

them to fit. If the 2 x 4’s are too low, use 2 x 6’s. If these

are high, cut them to the correct height.

WORK SUPPORT EXTENSIONS

CUTTING BOWED MATERIAL

When cutting flat pieces, first check to see if the material is bowed. If it is, make sure the material is positioned on the

table as shown in Fig. 30.

If the material is positioned the wrong way, as shown in Fig. 31, the workpiece will pinch the blade near the completion

of the cut.

Pulling the saw toward you while slide cutting can be dangerous, causing the saw to kick upward

and back toward you. ALWAYS PUSH

THE SAW FORWARD, AWAY FROM YOU and toward the

fence.

1. Place the workpiece (A) on the table and against the fence (Fig. 33).

Grasp the cuttinghead handle (B). DO NOT TURN THE SAW "ON" YET.

2. Pull the cuttinghead (C) Fig. 33 toward you and past the workpiece with

the cuttinghead in the “up” position. Depress the switch trigger to start

the saw.

3. Lower the cuttinghead (A) Fig. 34 on the workpiece and push the saw

away from you, toward the fence.

4, After the cut is complete (Fig. 35), release the switch trigger and keep the

cuttinghead down until the blade comes to a stop.

5. When the blade stops turning, raise the cuttinghead to the”up” position

(Fig. 36).

USING THE SAW AS A CONVENTIONAL MITER SAW

Before using this saw as a conventional miter saw, lock the

sliding action of the saw in the rear position.

1. Move the cuttinghead to the rear of the saw (toward the dust bag). Tighten the

lock knob (A) Fig. 37.

2. Place the workpiece against the fence.

3. Depress the switch trigger and lower the cuttinghead (B) through the workpiece

to make the cut.

3. After the cut is complete, release the switch trigger and let the blade come to

a stop before returning the cuttinghead to the “up” position.

DADO CUTTING

1. Loosen the wingnut (A) Fig. 38A, lower the cuttinghead to the desired cutting depth for the dado, tighten the bolt (B),

and tighten the wingnut.

2. Mark the workpiece where you want the cut. Place the workpiece against the fence.

3. Depress the switch trigger, lower the cuttinghead and make the first cut. Move the workpiece over the width of the saw

blade (right or left - depending on your mark),and make the next cut.

3. Continue this process until the dado cut is complete.

CUTTING CROWN MOULDING

One of the many features of the saw is the ease of cutting crown moulding. The following is an example of cutting both inside and

outside corners on 52°/38° wall angle crown moulding.

1. Move the table to the 31.62° right miter position and lock the table in position. NOTE: A positive stop is provided to find this angle

quickly.

2. Tilt the saw blade to the 33.86° left bevel position and tighten bevel lock handle. NOTE: A triangle indicator is provided on the

bevel scale to find this angle quickly.

3. Place the crown moulding on the table with the CEILING EDGE of the moulding against the fence, and make the cut, as shown

in Fig. B1.

NOTE: The piece of crown moulding used for the outside corner will always be on the right hand side of the blade, as shown at (A)

Fig. B1. The piece of crown moulding used for the inside corner will always be on the left hand side of the blade, as shown at (B)

Fig. B1.

4. To make the matching halves of the inside and outside corners, rotate the table to the 31.62° left miter position.

NOTE: A positive stop is provided to find this angle quickly. The saw blade is already tilted to the 33.86° left bevel position from the

previous cut.

5. Place the crown moulding on the table with the WALL EDGE of the crown moulding against the fence and make the cut. Again,

the piece of crown moulding used for the outside corner will always be on the right side of the blade, as shown at (C) Fig. B2. The

piece of crown moulding used for the inside corner will always be on the left side of the blade, as shown at (D) Fig. B2.

6. Fig. B3 illustrates the two outside corner pieces; (A) being the piece cut at (A) Fig. B1 and (C) being the piece cut at (C) Fig. B2.

7. Fig. B4 illustrates the two inside corner pieces; (B) being the piece cut at (B) Fig. B1, and (D) being the piece cut at (D) Fig. B2.

45-45 CROWN MOULDING

NOTE: If you are cutting crown moulding that is 45°-45°, follow the same procedure above, with the exception that the bevel position

will always be at 30° and the miter position will be 35-1/4° to the right or left.

OTHER ANGLES

NOTE: The above instructions are assuming the angle between the walls is 90°. If you need help cutting crown moulding set at angles

other than 90°, see the instruction sheet “CUTTING CROWN MOULDING” on the Delta Machinery web site at

www.deltamachinery.com.

2. To remove the saw blade, press the arbor lock (F) Fig. 45 and turn the screw (E) Fig. 44 clockwise. Remove the

screw, the outside blade flange, and the blade.

NOTE: Do not remove the inside blade flange.

3. Attach new saw blade making certain that the teeth of the saw blade are pointing down (Fig. 44). Attach the

outside blade flange (H) Fig. 44, and arbor screw (E). Press the arbor lock (F) Fig. 45. Use the arbor wrench counter-

clockwise to tighten the arbor screw

4. Replace screw and cover that was rotated to the rear in STEP 1.

Remove all wrenches before starting the machine.

BRUSH INSPECTION AND REPLACEMENT

BEFORE INSPECTING OR REMOVING BRUSHES, DISCONNECT THE MACHINE FROM THE

POWER SOURCE.

Brush life varies, depends on the load on the motor. Check the brushes after the first 50 hours of use of a new machine,

or after a new set of brushes has been installed.

After the first check, examine them after about 10 hours of use, until replacement is necessary.

The brush holders (A) Fig. 46 are located on the motor housing opposite each other. Fig. 47 illustrates one of the brushes

removed for inspection. When the carbon on either brush (B) is worn to 3/16" in length, or if either spring or shunt wire

(C) is burned or damaged in any way, replace both brushes. If the brushes are found serviceable after removing, reinstall

them in the same position.
