ENGLISH
Know The Air Compressor
READ THIS INSTRUCTION MANUAL AND SAFETY RULES
BEFORE OPERATING THE UNIT. Compare the illustrations
with the unit to familiarize yourself with the location of
various controls and adjustments. Save this manual for
future reference.
Description of Operation (Fig. A)
Become familiar with these controls before operating
the unit.
AUTO (-) / OFF (O) SWITCH
Place this switch (1) in the "AUTO (-)" position to provide
automatic power to the pressure switch and "OFF (O)" to
remove power at the end of each use.
PRESSURE SWITCH (NOT SHOWN)
The pressure switch (2) 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 compressor at
its "cut-out" pressure setting, the safety valve (3) will protect
against high pressure by "popping out" at its factory set
pressure (slightly higher than the pressure switch "cut-out"
setting).
TANK PRESSURE GAUGE (SUPPLIED)
The tank pressure gauge (4) indicates the reserve air
pressure in the tank.
AIR INTAKE FILTER
The filter (6) is designed to clean air entering the 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.
REGULATOR (SOLD SEPARATELY, NOT SHOWN)
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 tank outlet pressure
must never exceed the maximum pressure rating
of the tools or accessories.
AIR COMPRESSOR 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.
DRAIN VALVE
The drain valve (8) is located at the base of the air tank and is
used to drain condensation at the end of each use.
CHECK VALVE
When the air compressor is operating, the check valve (5) 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.
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. Move the Auto/Off switch to "OFF (O)" and unplug unit.
2. Allow the motor to cool.
3. Depress the red reset button (10) on the motor.
4. Plug the power cord into the correct branch circuit
receptacle.
5. Move the Auto/Off switch to "AUTO (-)".
How to Use The Unit
How to Stop
1. Move the Auto/Off switch to "OFF (O)".
2. Unplug unit when not in use.
Before Starting
WARNING: Do not operate this unit until you read this
instruction manual for safety, operation and
maintenance instructions.
Break-in Procedure
NOTICE: Risk of property damage. Serious damage may result if
the following break-in instructions are not closely followed.
This procedure is required before the air compressor is put into
service and when the check valve or a complete compressor
pump has been replaced.
1. Make sure the Auto/Off switch is in the "OFF (O)"
position.
2. Check oil level in pump. See Oil paragraph in the
Maintenance section for instructions.
3. Recheck all wiring. Make sure wires are secure at all
terminals connections. Make sure all contacts move
freely and are not obstructed.
4. Open the drain valve fully to permit air to
escape and prevent air pressure build up in the air tank
during the break-in period.
5. Move the Auto/Off switch to "AUTO (-)" position. The
compressor will start.
6. Run the compressor for 30 minutes. Make sure the
drain valve and all air lines are open so there is only a
minimal air pressure build-up in tank.
NOTE: After about 30 minutes, If the unit does not
operate properly, SHUT DOWN IMMEDIATELY, and
contact Product Service.
7. Check for excessive vibration. Re-adjust or shim air
compressor feet, if necessary.
8. After 30 minutes, turn the Auto/Off switch to the "OFF (O)"
position.
9. Close the drain valve.
10. Move the Auto/Off switch to the "AUTO (-)" position.
The air receiver will fill to "cut-out" pressure and the
motor will stop.
11. Check all air line fittings and connections/piping for air
leaks by applying a soap solution. Correct if necessary.
NOTE: Minor leaks can cause the air compressor to
overwork, resulting in premature breakdown or
inadequate performance.
12. The compressor is now ready for use.
