FIG.3
6.1. BREAK IN THE PUMP
6.1.1. Set the pressure switch to the OFF position (g.3).
6.1.2. Open tank drain valve by turning it counter-clockwise to permit the air to escape and prevent air pressure build-up in the air tank during
the break-in period (g.4).
6.1.3. Turn the air pressure regulator knob clockwise until it stops (g 5).
6.1.4. Plug in the power cord
Use a dedicated circuit. The compressor will use the full capacity of a typical 10A household circuit. If any other electrical devices are
drawing from the compressor’s circuit, the air compressor may fail to start voltage or an overload circuit can result in sluggish starting
that causes the motor overload protection system or circuit breaker to trip, especially in cold conditions. Disconnect the power cord only
after break-in process has been completed, otherwise the motor might get damaged.
6.1.5. Set the pressure switch to the ON position. The compressor will start. Run the compressor for 30 minutes. If it fails, turn it o
immediately.
NOTE: breaking-in the unit is only required prior to rst use.
6.1.6. After 30 minutes, turn o the pressure switch.
6.1.7. Close the tank drain valve by turning it clockwise (g 4).
6.1.8. Set the pressure switch to the ON position. The air receiver will ll to “cut-out” pressure and then the compressor’s motor will stop. The
compressor is now ready for use.
6.2. BEFORE EACH START-UP
6.2.1. Set the pressure switch to the OFF position (g.3).
6.2.2. Turn the air pressure regulator knob counter-clockwise until it stops (g.5).
6.2.3. Attach hose and accessories (sold separately).
6.3. HOW TO START
6.3.1. Close the tank drain valve (g.4).
6.3.2. Plug-in the power cord.
6.3.3. Set the pressure switch (g.3) to the ON position and allow the tank pressure to build. Motor will stop when tank pressure reaches cut-
out pressure.
6.3.4. Turn the air pressure regulator knob (g.5) clockwise until desired pressure is reached.
6.3.5. The compressor is ready for use.
6.4. HOW TO SHUT DOWN

DO NOT START
MAINTENANCE WORK
WARNING! Air contaminants taken into the compressor will aect optimum performance. Example: Body ller dust or paint overspray
will clog the pump intake lter and may cause internal damage to pump/motor components. Please note that any parts damaged by any
type of contamination will not be covered by warranty.
7.1. DAILY MAINTENANCE
7.1.1. Drain the tank. Through normal operation of your air compressor, condensation of water will accumulate in the tank. To prevent
corrosion of the tank from the inside, condensation must be drained at the end of every workday. Be sure to wear protective goggles.
Relieve the air pressure in the system then open the drain valve on the bottom of the tank to drain. Under cold conditions it is especially
important to drain the tank after each use to reduce the chance of problems resulting from the freezing of condensation water.
NOTE: Refer to 7.5 on how to drain the tank.
Pressure relief valve. Loosen the knob at the top of the safety valve to ensure normal exhaust. Tighten it again and remove any debris.
7.2. MONTHLY MAINTENANCE
7.2.1. Test for leaks. Check that all connections are tight. Small leaks in the tank, hoses,connections or transfer tubes will substantially
reduce the air compressor and tool performance. Spray a small amount of soapy water around the area of suspected leaks with a spray
bottle. If bubbles appear, repair, replace or reseal the faulty component. Do not over-tighten any connections.

8. TROUBLESHOOTING
PROBLEM POSSIBLE CAUSE SOLUTION
The motor will not run
or start.
The power cord is not plugged in. Plug the power cord into a grounded outlet.
The pressure switch is in the OFF position. Set the pressure switch to the ON position.
The extension cord is the wrong wire gauge or is too
long.
Check extension cord information for the proper wire
gauge and cord length.
The motor’s thermal overload protection has tripped. Turn the air compressor o, unplug the power cord
and wait until the motor has cooled down. Plug
in the power cord only after the motor has cooled
down, and wait at least 5 minutes to make sure the
thermal overload protector has recovered.
A fuse has blown or a circuit breaker has been
tripped.
Replace the fuse or reset the circuit breaker.
Verify that the fuse has the proper amperage.
Check for low voltage conditions.
Disconnect any other electrical appliances from the
circuit or operate the compressor on a dedicated
circuit.
The air tank pressure exceeds the preset pressure
switch limit.
The motor will start automatically when the tank
pressure drops below the cut-in pressure.
The safety valve is stuck open. Clean or replace the safety valve.
Electrical connections are lose. Contact an authorized service centre
The motor, capacitor or safety valve is defective. Contact an authorized service centre
The motor runs
continuously when the
pressure switch is in
the ON position.
The pressure switch does not shut o the motor
when the air compressor reaches the cut-out
pressure and the safety valve activates.
Set the pressure switch to the OFF position. If the
motor does not shut o, unplug the air compressor.
If the pressure switch is defective, replace it.
The compressor’s capacity is not enough. Check the air requirements of the accessory that
is being used. If it is higher than the L/MIN and
pressure supplied by the compressor (page 2), a
larger capacity air compressor is needed. Most
accessories are rated at 25% of actual
L/MIN while running continuously.
The regulator does not
regulate the pressure.
The regulator or its internal parts are dirty or
damaged.
Replace the regulator.
