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 Auto/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 AUTO position.

INSTALLING HOSES
WARNING: Risk of unsafe operation. Firmly grasp hose in hand when installing or discon-
necting to prevent hose whip.
1. Ensure regulated pressure gauge reads 0 psi.
2. Grasp the hose at the quick connect plug and push the plug into the quick connect
body (E). Coupler will snap into place.
3. Grasp the hose and pull to ensure coupler is seated.
DISCONNECTING HOSES
WARNING: Risk of unsafe operation. Firmly grasp hose in hand when installing or discon-
necting to prevent hose whip.
1. Ensure regulated pressure gauge reads 0 psi.
2. Pull coupler on quick connect body back to release Quick Connect plug on hose.

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 appro-
priate grounding plug.
1. The cord set and plug (M) with this unit 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 quali-
fied electrician.
DANGER: Risk of Electrical Shock. IMPROPER GROUNDING CAN RESULT IN
ELECTRICAL SHOCK.

NOTICE: Risk of Property Damage. 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 exten-
sion 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.

Refer to the Voltage and Minimum Branch Circuit Requirements under Pump/Motor
Specifications.
CAUTION: Risk of Overheating. 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.

NOTE: If compressor is connected to a circuit protected by fuses, use only time delay
fuses. Time delay fuses should be marked “D” in Canada and “T” in the US.
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.

Place the air compressor in a clean, dry and well ventilated area at least 12" (30.5 cm) away
fromthewallorotherobstructionsthatwillinterferewiththeflowofair.Keepthecompressor
away from areas that have dirt and/or volatile fumes in the atmosphere. These impurities may
clog the intake filter and valves, causing inefficient operation.
WARNING: The air compressor pump and shroud are designed to allow for proper cool-
ing. The ventilation openings on the compressor are necessary to maintain proper operating
temperature. Do not place rags or other containers on or near these openings.
Place the air compressor on a flat surface resting on the rubber feet and wheels.
ELECTRICAL
Refer to all safety instructions before using unit. Observe extension cord safety instructions
if necessary. Always move the Auto/Off switch (A) to the OFF position before removing the
plug from the outlet.
TRANSPORTING (FIG. 3)

the unit is secured with straps to prevent tipping. Use care when driving to prevent tipping
the unit over in the vehicle. Damage can occur to the compressor or surrounding items if the
compressor is tipped.
LIFTING
Always use two people when lifting and lift from the recommended lift points (N). DO NOT
lift by wheels or shroud.
MOVING
CAUTION: The wheels and handle do not provide adequate clearance, stability, or
support for pulling the unit up and down stairs or steps. The unit must be lifted or
pushed up a ramp.
1. Grasp handle of compressor and tilt compressor back to rest on wheels.
WARNING: Risk of Unsafe Operation. Ensure proper footing and use caution when rolling
compressor so that unit does not tip or cause loss of balance.

3. Ensure air tank is drained, see Draining Air Tank under Maintenance.
4. Ensure the drain valve (H) is closed.
5. Ensure safety valve (G) is functioning properly, see Checking Safety Valve under
Maintenance.
6. Pull the regulator knob (D) out and turn counterclockwise until fully closed. Ensure regu-
lated pressure gauge reads 0 psi. Push knob in to lock in place.
7. Attach hose and accessories. NOTE: Always use a minimum 3/8" (9.5 mm) or greater air
hose rated at 300 psi.

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 when using the compressor.
Before starting compressor, pull the ring on the safety valve to make sure that the safety
valve operates freely. NOTE: Ring may be difficult to pull when air tank pressure is at 0 psi.
If the valve is stuck or does not operate smoothly, it must be replaced with the same type
of valve.

WARNING: Risk of unsafe operation. Risk from noise. Air tanks contain high pres-
sure 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. Always wear proper hearing protection during use. Under
some conditions and duration of use, noise from this product may contribute to hearing loss.
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 sub-
stances which may be regulated and must be disposed of in accordance with local, state,
and federal laws and regulations.
WARNING: Risk of bursting. Drain air tank daily. Water will condense in 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.
1. Ensure Auto/Off switch is in the OFF position.
2. Place a suitable container under the drain valve (H) to catch discharge.
3. Grasp lever on drain valve.
4. Slowly rotate lever to gradually bleed air from air tank.
