Craftsman CMXECXM301 Instruction Manual page 9

REGULATOR
Controls the air pressure shown on the outlet pressure
gauge. Turn regulator knob (18) 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 ai 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.
REGULATED PRESSURE GAUGE
The regulated pressure gauge indicates the air pressure
available at the outlet side of the regulator. This pressure is
controlled by the regulator. The regulator is designed to
allow pressures up to 150 PSI.
UNIVERSAL QUICK CONNECT BODY
The universal quick connect body (9) accepts the three
most popular styles of quick connect plugs: Industrial,
automotive, and ARO. One hand push-to-connect
operation makes connections simple and easy.
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" 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".
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"
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" 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.
