WARNING: RISK OF BURSTING

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

Safety Commission published Release # 02-108 concerning air

compressor 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:

ON (I) / OFF (O) SWITCH

Place this switch (A) in the ON (I) position to

A

provide automatic power to the pressure switch

and OFF (O) to remove power at the end of

each use.

PRESSURE SWITCH

The pressure switch automatically starts the

motor when the air tank pressure drops below

the factory set cut-in pressure. It stops the motor when the air tank

pressure reaches the factory set cut-out pressure.

SAFETY VALVE

If the pressure switch does not shut off the air

G

F

compressor at its cut-out pressure setting, the

safety valve (G) will protect against high

pressure by popping out at its factory set

pressure (slightly higher than the pressure

switch cut-out setting).

CHECK VALVE

When the air compressor is operating, the

check valve (F) 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.

the reserve air pressure in the tank.

OUTLET PRESSURE GAUGE

The outlet pressure gauge (C)

indicates the air pressure available at

the outlet side of the regulator. This

pressure is controlled by the regulator

and is always less than or equal to the tank pressure.

REGULATOR

The regulator (D) controls the air pressure shown on the outlet

pressure gauge. Turn regulator knob clockwise to increase pressure

and counterclockwise to decrease pressure.

WARNING: Risk of Bursting. Too much air pressure causes a

hazardous risk of bursting. Check the manufacturer’s maximum

pressure rating for air tools and accessories. The regulator outlet

pressure must never exceed the maximum pressure rating.

UNIVERSAL QUICK CONNECT BODIES

The universal Quick Connect body (E) accepts the three most

popular styles of Quick Connect plugs: Industrial, automotive, and

ARO. The two quick connect bodies allow the use of two tools at the

same time.

DRAIN VALVE

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

tank and is used to drain condensation at the end of

each use.

See Draining Air Tank under

Maintenance.

COOLING SYSTEM

This compressor contains an advanced design cooling system.

It is normal for this fan to blow air through the vent holes in large

amounts. The cooling system is working when air is expelled.

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.

MOTOR OVERLOAD PROTECTOR

The motor has a thermal overload protector. If the motor overheats

for any reason, the overload protector will shut off the motor. The

motor must be allowed to cool down before restarting. To restart:

1. Set the On/Off lever to “Off” and unplug unit.

2. Allow the motor to cool.

3. Plug the power cord into the correct branch circuit receptacle.

4. Set the Auto/Off lever to “On” position.

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 with a cord having a

grounding wire with an appropriate grounding plug.

1. The cord set and plug (J) with this unit

L

contains a grounding pin (L). This plug

MUST be used with a grounded outlet

(K).

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.

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 condensate that

accumulates 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 On/Off switch (A) is in the OFF position.

2. Move compressor into an inclined position so drain valve (H) is

at the lowest point (this will assist in removing moisture, dirt, etc.

from air tanks)

3. Place a suitable container under the drain valve to catch

discharge.

4. Grasp black lever on drain valve.

5. Slowly rotate lever to gradually bleed air from air tank.

6. When air tank pressure gauge reads 10 psi, rotate valve to the

fully open position.

7. Close drain valve when finished.

CFM: Cubic feet per minute.

SCFM: Standard cubic feet per minute; a unit of measure of air delivery.

PSI: Pounds per square inch; a unit of measure of pressure.

certified independent safety laboratories and meet the applicable Standards for Safety.

Cut-In Pressure: While the motor is off, air tank pressure drops when accessory is used. When the tank pressure drops to a certain low

level the motor will restart automatically. The low pressure at which the motor automatically restarts is called cut-in pressure.

Cut-Out Pressure: When an air compressor is turned on and begins to run, air pressure in the air tank begins to build. It builds to a

certain high pressure before the motor automatically shuts off, protecting your air tank from pressure higher than its capacity. The high

pressure at which the motor shuts off is called cut-out pressure.

Branch Circuit: The circuit carrying electricity from electrical panel to outlet.

Duty Cycle: This air compressor pump is capable of running continuously. However, to prolong the life of your air compressor, it

is recommended that a 50%-75% average duty cycle be maintained; that is, the air compressor pump should not run more than

30-45 minutes in any given hour.
