DANGER: RISK OF BURSTING

Air Tank: On February 26, 2002, the U.S. Consumer Product Safety

Commission published Release # 02-108 concerning air compres-

sor tank safety:

Air compressor receiver tanks do not have an infinite life. Tank life is

dependent upon several factors, some of which include operating

conditions, ambient conditions, proper installations, field modifica-

tions, and the level of maintenance. The exact effect of these fac-

tors on air receiver life is difficult to predict.

If proper maintenance procedures are not followed, internal corro-

sion to the inner wall of the air receiver tank can cause the air tank

to unexpectedly rupture allowing pressurized air to suddenly and

forcefully escape, posing risk of injury to consumers.

Your compressor air tank must be removed from service by the end

of the year shown on your tank warning label.

The following conditions could lead to a weakening of the air tank,

and result in a violent air tank explosion:

WHAT CAN HAPPEN HOW TO PREVENT IT

• Failure to properly drain

condensed water from air

tank, causing rust and thinning

of the steel air tank.

• Drain air tank daily or after each

use. If air tank develops a leak,

replace it immediately with

a new air tank or replace the

entire compressor.

• Modifications or attempted

repairs to the air tank.

• Never drill into, weld or make

any modifications to the air

tank or its attachments. Never

attempt to repair a damaged or

leaking air tank. Replace with a

new air tank.

• Unauthorized modifications to

the safety valve, or any other

components which control air

tank pressure.

• The air tank is designed

to withstand specific

operating pressures. Never

make adjustments or parts

substitutions to alter the factory

set operating pressures.

Attachments & Accessories:

• Exceeding the pressure rating

of air tools, spray guns, air

operated accessories, tires

and other inflatables can

cause them to explode or

fly apart, and could result in

serious injury.

• Follow the equipment

manufacturers

recommendation and never

exceed the maximum allowable

pressure rating of attachments.

Never use compressor to

inflate small low pressure

objects such as children’s toys,

footballs, basketballs, etc.

Tires:

• Over inflation of tires could

result in serious injury and

property damage.

• Use a tire pressure gauge to

check the tires pressure before

each use and while inflating

tires; see the tire sidewall for

the correct tire pressure.

NOTE: Air tanks, compressors

and similar equipment used to

inflate tires can fill small tires

very rapidly. Adjust pressure

regulator on air supply to no

more than the rating of the

tire pressure. Add air in small

increments and frequently use

the tire gauge to prevent over

inflation.

NOTE: Assembling quick connect bodies (L) to air outlet (F)

and quick connect plugs to hose ends make connecting and

disconnecting hoses simple and easy. Quick connect bodies

and plugs are available for purchase from your local dealer or

authorized service center.

DISCONNECTING HOSES

WARNING: Risk of unsafe operation. Firmly grasp hose in hand

when installing or disconnecting to prevent hose whip.

1. Ensure regulated pressure gauge reads 0 psi.

2. Remove hose from air outlet (F).

Lubrication and Oil

AIR COMPRESSOR

The air compressor pump was filled WITH oil at the manufacturer.

Check air compressor pump oil level before operating unit. See

Compressor Pump Oil under Maintenance.

Compatibility

Air tools and accessories that are run off the compressor must be

compatible with petroleum based products. If you suspect that a

material is not compatible with petroleum products, an air line filter

for removal of moisture and oil vapor in compressed air is required.

NOTE: Always use an air line filter to remove moisture and oil vapor

when spraying paint.

Location

• Locate the air compressor in a clean, dry, and well ventilated

area.

• Located the air compressor at least 12” (30.5 cm) away from

the wall or other obstructions that will interfere with the flow of

air.

• Locate the air compressor as close to the main power supply

as possible to avoid using long lengths of electrical wiring.

NOTE: Long lengths of electrical wiring could cause power loss

to the motor.

• The air filters must be kept clear of obstructions which could

reduce air flow to the air compressor.

HUMID AREAS

In frequently humid areas, moisture may form in the pump and

produce sludge in the oil, causing running parts to wear out

prematurely. Excessive moisture is especially likely to occur if

the unit is located in an unheated area that is subject to large

12

English

temperature changes. Two signs of excessive humidity are external

condensation on the pump when it cools down and a “milky”

appearance in compressor oil. You may be able to prevent

moisture from forming in the pump by increasing ventilation or

operating for longer intervals.

Wiring Instructions

WARNING: Improper electrical installation of this product

may void its warranty and your fire insurance. Have circuit wiring

performed by qualified personnel such as a licensed electrician who

is familiar with the current national electrical code and any prevailing

local electrical codes.

WARNING: Risk of electrical shock. Improper electrical grounding

can result in electrical shock. The wiring should be done by a

qualified electrician.

A qualified electrician needs to knows the following before wiring:

1. The amperage rating of the electrical box should be adequate.

Refer to the Specifications, in the parts manual, for this

information.

2. The supply line should have the same electrical characteristics

(voltage, cycle, phase) as the motor. Refer to the motor

nameplate, on side of motor, for this information.

NOTE: The wiring used must be rated for the motor nameplate

voltage, plus or minus 10%. Refer to local codes for recommended

wire sizes, correct wire size, and maximum wire run; undersize wire

causes high amp draw and overheating to the motor.

WARNING: Risk of electrical shock. Electrical wiring must

be located away from hot surfaces such as manifold assembly,

compressor outlet tubes, heads, or cylinders.

Grounding Instructions

WARNING: Risk of electrical shock. In the event of a short circuit,

grounding reduces the risk of shock by providing an escape wire for

the electric current. This air compressor must be properly grounded.

The portable air compressor is equipped

P

O

Q

with a cord having a grounding wire with an

appropriate grounding plug.

1. The cord set and plug (O) with this

unit contains a grounding pin (P). This

plug MUST be used with a grounded

outlet (Q).

IMPORTANT: The outlet being used must be installed and grounded

in accordance with all local codes and ordinances.

2. Ensure the outlet being used has the same configuration as the

grounded plug. DO NOT USE AN ADAPTER.

3. Inspect the plug and cord before each use. Do not use if there

are signs of damage.

4. If these grounding instructions are not completely understood,

or if in doubt as to whether the compressor is properly grounded,

have the installation checked by a qualified electrician.

DANGER: Risk of electrical shock. IMPROPER GROUNDING

CAN RESULT IN ELECTRICAL SHOCK.

• Do not modify the plug provided. If it does not fit the available

outlet, a correct outlet should be installed by a qualified

electrician.

• Repairs to the cord set or plug MUST be made by a qualified

electrician.

Extension Cords

If an extension cord must be used, be sure it is:

• a 3-wire extension cord that has a 3-blade grounding plug, and

13

English

a 3-slot receptacle that will accept the plug on the product

• in good condition

• plug is not worn

• no longer than 50 feet (15.2 m)

• 12 gauge (AWG) or larger. (Wire size increases as gauge number

decreases. 10 AWG and 8 AWG may also be used. DO NOT

USE 14 OR 16 AWG.)

NOTICE: The use of an undersized extension cord will cause volt-

age to drop resulting in power loss to the motor and overheating.

Instead of using an extension cord, increase the working reach of

the air hose by attaching another length of hose to its end. Attach

additional lengths of hose as needed. Always use a minimum 3/8”

(9.5 mm) or greater air hose rated at 300 psi.

Voltage and Circuit Protection

Refer to the Voltage and Minimum Branch Circuit Requirements

under Specifications.

CAUTION: Certain air compressors can be operated on a

15 amp circuit if the following conditions are met.

• Voltage supply to circuit must comply with the National

Electrical Code.

• Circuit is not used to supply any other electrical needs.

• Extension cords comply with specifications.

• Circuit is equipped with a 15 amp circuit breaker or 15 amp

time delay fuse. NOTE: If compressor is connected to a cir-

cuit protected by fuses, use only time delay fuses. Time delay

fuses should be marked “D” in Canada and “T” in the U.S.

If any of the above conditions cannot be met, or if operation of the

compressor repeatedly causes interruption of the power, it may be

necessary to operate it from a 20 amp circuit. It is not necessary to

change the cord set.

Draining Air Tank (Fig. 3)

WARNING: Risk of unsafe operation. Air tanks contain high

pressure air. Keep face and other body parts away from outlet of

drain. Use eye protection [ANSI Z87.1 (CAN/CSA Z94.3)] when

draining as debris can be kicked up into face.

WARNING: Risk from noise. Use ear protection (ANSI S12.6

(S3.19) as air flow noise is loud when draining.

NOTE: All compressed air systems generate condensation that accu-

mulates in any drain point (e.g., tanks, filter, aftercoolers, dryers). This

17

English

condensate contains lubricating oil and/or substances which may be

regulated and must be disposed of in accordance with local, state,

and federal laws and regulations.

1. Set the Auto/Off switch to “Off”.

2. Turn the regulator knob counterclockwise to set the outlet

pressure to zero.

3. Remove the air tool or accessory.

4. Pull ring on safety valve allowing air to bleed from the tank until

tank pressure is approximately 20 psi. Release safety valve

ring.

5. Drain water from air tank by opening drain valve (counterclock-

wise) on bottom of tank.

WARNING: Risk of bursting. Water will condense in the air tank.

If not drained, water will corrode and weaken the air tank causing a

risk of air tank rupture.

NOTICE: Risk of property damage. Drain water from air tank may

contain oil and rust which can cause stains.

6. After the water has been drained, close the drain valve (clock-

wise). The air compressor can now be stored.

NOTE: If drain valve is plugged, release all air pressure. The valve

can then be removed, cleaned, then reinstalled.

Compressor Pump Oil (Fig. 4)

NOTICE: Risk of property damage. Use air compressor oil only.

Multi-weight automotive engine oils like 10W30 should not be used

in air compressors. They leave carbon deposits on critical compo-

nents, thus reducing performance and compressor life.

NOTE: Use synthetic blend, non-detergent air compressor oil.

NOTE: Crankcase oil capacity is approximately 11.35 fluid ounces

(473,2 ml).

Checking

1. The oil level should be to the middle of the sight glass (X).

2. If needed remove oil fill plug (Y) and slowly add oil until it

reaches the middle of the sight glass.

Changing

WARNING: Drain tank to release air pressure before removing the

oil fill cap or oil drain plug.

1. Remove the oil fill plug (Y).

2. Remove the oil drain plug (W) and drain oil into a suitable

container.

3. Replace the oil drain plug (W) and tighten securely

4. Slowly add compressor oil until it reaches the middle of the

sight glass (X). NOTE: When filling the crankcase, the oil

flows very slowly into the pump. If the oil is added too quickly,

it will overflow and appear to be full.

CAUTION: Overfilling with oil will cause premature compressor

failure. Do not overfill.

5. Replace oil fill plug (Y) and tighten securely.

Belt Replacement

WARNING: This unit starts automatically. ALWAYS shut off

and unplug the compressor, and bleed all pressure from the

system before servicing the compressor, and when the

compressor is not in use. Do not use the unit with the shrouds

or belt guard removed. Serious injury could occur from contact

with moving parts. Hot surfaces. Risk of burn. Pump head, and

surrounding parts are very hot, do not touch (see the Hot

Surfaces identified in Fig. 2). Allow compressor to cool prior to

servicing.

1. Set the Auto/Off lever to “Off”, unplug the unit, and relieve all

air pressure from the air tank.

2. Remove the front of the beltguard by removing the screws (Z)

using a Torx T25 bit.

3. Mark motor position on

Z

saddle.

4. Loosen the motor

mounting screws and

slide the motor toward

the air compressor.

5. Remove the belt and

replace with a new one.

6. See the Adjusting Belt

Tension before tighten-

ing motor mounting screws.

Adjusting Belt Tension

1. Slide motor into original position, line the motor up with the

mark made earlier on saddle.

2. Tighten two outside

Downward Force

Deflection

motor mounting

screws enough to

hold the motor in

place for checking

pulley and flywheel

alignment.

3. The belt should deflect

1/2” (13 mm)at mid-

way between the pul-

ley and the flywheel

when a 5 pound

(2.26kg.) weight is applied at the midway point.

3. When proper belt tension is achieved, tighten all four motor

mounting screws. Torque to 20-25 ft-lbs (27.1–33.9 Nm).

NOTE: Once the motor pulley has been moved from its factory set

location, the grooves of the flywheel and pulley must be aligned to

19

English

within 1/16” (1.6 mm) to prevent excessive belt wear. Verify the

alignment by performing the following Motor Pulley/Flywheel -

Alignment.

Motor Pulley/Flywheel Alignment

NOTE: Once the motor pulley has been moved from its factory set

location, the grooves of the flywheel and pulley must be aligned to

within 1/16” (1.6 mm) to prevent excessive belt wear.

The air compressor flywheel and motor pulley must be in-line (in the

same plane) within 1/16” (1.6 mm) to assure belt retention within

flywheel belt grooves. To check alignment, perform the following

steps:

1. Set the Auto/Off lever to “Off”, unplug the unit, and relieve all

air pressure from the air tank.

2. Remove belt guard.

3. Place a straightedge against the outside of the flywheel and the

motor drive pulley.

4. Measure the distance

between the edge of

the belt and the

straightedge at points

A1 and A2 in figure.

The difference

between measure-

ments should be no more than 1/16” (1.6 mm).

5. If the difference is greater than 1/16” (1.6 mm) loosen the set

screw holding the motor drive pulley to the shaft and adjust the

pulley’s position on the shaft until the A1 and A2 measurements

are within 1/16” (1.6 mm) of each other.

6. Tighten the motor drive pulley set screw.

7. Visually inspect the motor drive pulley to verify that it is per-

pendicular to the drive motor shaft. Points B1 and B2 of Figure

should appear to be equal. If they are not, loosen the setscrew

of the motor drive pulley and equalize B1 and B2, using care

not to disturb the belt alignment performed in step 2.

8. Retighten the motor drive pulley setscrew. Torque to 145–165 in lbs

(16.4–20.3Nm).
