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 unloader valve,

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.

• Excessive vibration can

weaken the air tank and

cause rupture or explosion.

Excessive vibration will occur if

the compressor is not properly

mounted or if engine operates

above recommended RPM.

• Do not remove the stiffener bar

connecting the compressor

pump to the engine, except

to adjust belt tension. Then

securely tighten the stiffener

bar bolts. This bar controls unit

vibration.

English

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.

DANGER: RISK OF INJURY OR PROP ER TY DAMAGE WHEN

TRANSPORTING OR STORING

WHAT CAN HAPPEN HOW TO PREVENT IT

• Oil can leak or spill and could

result in fire or breathing

hazard; serious injury or

death can result. Oil leaks will

damage carpet, paint or other

surfaces in vehicles or trailers.

• Always place compressor

on a protective mat when

transporting to protect against

damage to vehicle from leaks.

Remove compressor from

vehicle immediately upon

arrival at your destination.

Always keep compressor level

and never lie on its side.

OPERATING YOUR UNIT. Compare the illustrations with your

unit to familiarize yourself with the location of various controls

and adjustments. Save this manual for future reference.

FEATURES

ELECTRIC START

The engine switch (C) can be placed in three

C

positions; START, RUN and OFF. See Starting

under Operation for complete starting

instructions.

UNLOADER VALVE

When the maximum air tank pressure is obtained, the unloader

valve (F) will blow-off. This will cause the compressor to exhaust

the air to the atmosphere and not the tank.

Manual Lock: The manual lock allows you to

OPEN

F

CLOSED

F

manually unload the compressor with air

pressure in the air tank. To operate the manual

lock:

Rotate the manual lock unloader lever to the

open position to prevent air tank pressure

buildup. Rotate manual lock unloader lever to

the closed position after starting the engine to allow air tank pressure

to build. NOTE: Air will not build in tank when manual lock unloader

lever in the open position.

SAFETY VALVE

This valve (G) is designed to prevent system

G

failures by relieving pressure from the system

when the compressed air reaches a predeter-

11

English

mined level. The valve is preset by the manu facturer and must not be

removed or modified in any way.

CHECK VALVE

When the air compressor is operating, the

O

check valve (O) is open, allowing compressed

air to enter the air tank. When the air

compressor reaches cut-out pressure, the

check valve closes, allowing air pressure to

remain inside the air tank.

AIR INTAKE FILTER

The filter (A) is designed to clean air entering the

A

pump. To ensure the pump continually receives a

clean, cool, and dry air supply the filter must always

be clean and the filter intake must be free from

obstructions.

AIR TANK DRAIN VALVE

The drain valve (H) is located at the base of

H

the air tank and is used to drain

condensation at the end of each use. See

Draining Air Tank under Maintenance.

TANK PRESSURE GAUGE

The tank pressure gauge (D) indicates the

D

reserve air pressure in the tank.

GLOBE VALVE/AIR DISCHARGE VALVE:

(sold separately, not shown)

Opens and closes air distribution from compressor.

REGULATOR (sold separately, not shown):

An air pressure regulator or a separate air transformer which

combines the functions of air regulation and/or moisture and dirt

removal is recommended for most applications.

AIR COMPRESSOR PUMP

The pump compresses air into the air tank. Working air is not available

until the compressor has raised the air tank pressure above that

required at the air outlet.

GASOLINE ENGINE

The gasoline engine powers the pump. The engine drives a pulley

and belt, which transfers power from the engine to the pump

pistons via a flywheel and a crankshaft. The flywheel fan helps cool

the pump.

THROTTLE CONTROL

When maxi mum air tank pres sure is reached and the unloader valve

vents air, it activates the throttle control on the engine. This gas

saving feature holds the engine at a factory-set idling speed until air

pressure in the air tank drops to reset pressure. The unloader valve

then reactivates the throttle control and accelerates the engine to

full throttle.

LOW OIL SHUT DOWN SENSOR

The air compressor engine is equipped with a low oil shutdown

sensor. This is a safety device designed to protect your engine

from damage in the event the oil level in the crankcase is below

minimum.

If the oil in the engine gets low while the air compressor is running it

will automatically shut down the engine and will not restart until oil

is added to the engine. If the oil is low before start-up, the engine

will not start until oil is added.

NOTE: The low oil shutdown sensor is very sensitive. You must fill

the engine to the full mark on the dipstick to inactivate this safety

device.

12

English

INSTALLATION

Assembly

(refer to Fig. 1, pg. 2)

Unpack the air compressor. Inspect the unit for damage. If the

unit has been damaged in transit, contact the carrier and

complete a damage claim. Do this immediately because there are

time limitations to damage claims.

The carton should contain:

• air compressor

• operator and parts manuals

• engine manual

• vibration pads (4)

Check the compressor’s serial label to ensure that you have

received the model ordered, and that it has the required pressure

rating for its intended use.

INSTALLING HOSES

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

when installing or disconnecting to prevent hose whip.

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

tank pressure is 0 psi. Release safety valve ring.

2. Apply sealant tape to hose threads.

3. Assemble hose to air outlet (E). IMPORTANT: Do not assemble

splitters directly to the air outlet (E).

NOTE: Assembling quick connect bodies to air outlet 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. Pull ring on safety valve allowing air to bleed from the tank until

tank pressure is 0 psi. Release safety valve ring.

2. Remove hose from air outlet (E).

Lubrication and Oil

ENGINE

1. The engine was filled WITH oil at the manufacturer. Check

engine oil level before operating unit. If necessary, fill engine

to the appropriate level with recommended oil, see engine's

instruction manual supplied by engine manufacturer for correct

procedure.

2. Add fuel to engine. See engine's instruction manual supplied by

engine manufacturer for correct procedure.

WARNING: Risk of explosion or fire. Gasoline vapor is highly

flammable. Refuel outdoors preferably, or only in well-ventilated

areas. Do not refuel or check gasoline level while the engine is

running. Do not store, spill or use gasoline near an open flame, a

source of sparks (such as welding), or near operating electrical

equipment.

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

13

English

when spraying paint.

Location

WARNING: Risk of breathing. Exhaust from the gasoline engine

contains deadly carbon monoxide, which is odorless and toxic.

Operate engine only in well ventilated areas.

NOTICE: Risk of property damage. In order to avoid damaging

the air compressor, do not allow the unit to be tilted more than

10º when operating.

Place air compressor at least 4 ft (1.2 m) away from obstacles that

may prevent proper ventilation. Keep unit away from areas that

have dirt, vapor and volatile fumes in the atmosphere which may

clog and gum up the intake filter and valves, causing inefficient

operation.

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

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.

NOISE CONSIDERATIONS

Consult local officials for information regarding acceptable noise

levels in your area. To reduce excessive noise, use vibration mounts

or silencers, relocate the unit or construct total enclosures or baffle

walls. Contact a D

e

WALT service center or call 1-888-895

-

4549 for

assistance.

Anchoring of the Air Compressor

WARNING: Risk of bursting. Excessive vibration can weaken

the air tank and cause an explosion. The compressor must be

properly mounted.

The air compressor MUST be bolted to a level, solid surface.

Remove the compressor from the shipping pallet and place it on

the floor or a hard, level surface. The compressor must be level to

ensure proper lubrication of the pump and good drainage of the

moisture in the tank.

The shipping pallet is not designed as a base for an operating

compressor. Operating the compressor while it is on the pallet

will void your warranty.

To prevent damage to tank and

pump, the tank must be shimmed

so the pump is level within 1/8”

per lineal foot maximum to

distribute oil properly. Fasten to

floor and NEVER force tank feet

to floor without shims when tightening. We also recommend the

use of vibration pads (094-0137) under tank feet (see X).

NOTE: If the compressor is mounted on a vehicle, the vehicle

must be parked on a level surface while operating the compressor.

This is to ensure proper lubrication of the pump and gasoline

engine.

WARNING: To avoid personal injury, always shut off the

gasoline engine and relieve all air pressure from the system

before performing any service on the air compressor.

To ensure efficient operation and longer life of the air compressor

outfit, a routine maintenance schedule should be prepared and fol-

lowed. The following routine maintenance schedule is geared to an

outfit in a normal working environment operating on a daily basis.

If necessary, the schedule should be modified to suit the condi-

tions under which your compressor is used. The modifications will

depend upon the hours of operation and the working environment.

Compressor outfits in an extremely dirty and/or hostile environment

will require a greater frequency of all maintenance checks.

NOTE: See Operation section for the location of controls.

Checking Safety Valve (refer to Fig. 1, pg. 2)

WARNING: Hot surfaces. Risk of burn. Tubes, 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.

WARNING: Risk of bursting. If the safety valve does not work

properly, over-pressurization may occur, causing air tank rupture

or an explosion.

WARNING: Risk from flying objects. Always wear certified

safety equipment: ANSI Z87.1 eye protection (CAN/CSA Z94.3)

with side shields.

English

Before starting compressor, pull the ring on the safety valve

to make sure that the safety valve operates freely. If the valve

is stuck or does not operate smoothly, it must be replaced with

the same type of valve.

Checking Air Filter

WARNING: Hot surfaces. Risk of burn. Tubes, 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.

A dirty air filter will not allow the compressor to operate at full

capacity. Keep the air filter clean at all times.

1. Ensure engine START/RUN/OFF switch (C) is in the OFF posi-

tion.

2. Allow unit to cool.

3. Remove the wing nut (P).

4. Remove the outer metal cover (Q).

5. Remove element (R) from filter base.

R

6. If element needs cleaning, blow out

with air. Replace if needed. Purchase

replacement parts from your local deal-

er or authorized service center. Always

use identical replacement parts.

7. Place element back in filter base.

8. Place the outer metal cover back over

the filter element.

9. Secure with the wing nut.

CAUTION: Risk of unsafe operation. Do not operate without

air filter.

Draining Air Tank (refer to Fig. 3, pg. 17)

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

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. Ensure engine START/RUN/OFF switch (C) is in the OFF posi-

tion.

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

tank pressure is approximately 20 psi. Release safety valve ring.

3. 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.

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

wise).

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

can then be removed, cleaned, then reinstalled.

Compressor Pump Oil (refer to Fig. 4, pg. 20)

WARNING: Hot surfaces. Risk of burn. Tubes, 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.

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 full synthetic non-detergent air compressor oil.

NOTE: Crankcase oil capacity is approximately 53 fluid ounces

(1567 ml).

Checking

1. Ensure engine START/RUN/OFF switch (C) is in the OFF

Position.

2. The oil level should be to the middle of the sight glass (S).

3. If needed remove oil fill plug (I) and slowly add oil until it reaches

the middle of the sight glass.

Changing

WARNING: Hot surfaces. Risk of burn. Tubes, 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.

WARNING: Drain tank to release air pressure before removing

the oil fill cap or oil drain plug.

1. Ensure engine START/RUN/OFF switch (C) is in the OFF

position.

2. Allow the unit to cool.

3. Disconnect spark plug wire.

4. Drain air tank.

5. Remove the oil fill plug (I).

6. Remove the oil drain plug (J) and drain oil into a suitable con-

tainer.

7. Replace the oil drain plug (J) and tighten securely

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

sight glass (S). 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.

9. Replace oil fill plug (I) and tighten securely.

10. Reconnect spark plug wire.

NOTE: Pump oil contains substances that are regulated and must

be disposed of in accordance with local, state and federal laws and

regulations.
