PREPARATION FOR USE

Pre-Start Checklist (Fig. 1)
1. Ensure the On/Off switch (A) is in the OFF position.
2. Plug the power cord into the correct branch circuit receptacle. See
Voltage and Circuit Protection under Installation.
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. Turn regulator knob (D) counterclockwise until fully closed. Ensure
regulated pressure gauge reads 0 PSI.
7. Visually inspect air hose, replace if needed.
8. Attach hose and accessories.
WARNING: Risk of unsafe operation. Firmly grasp air hose in hand
when installing or disconnecting to prevent hose whip.
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.
Initial Set-up (Fig. 1)
WARNING: Do not operate this unit until you read and understand
this instruction manual for safety, operation and maintenance
instructions.
BREAK-IN PROCEDURE
WARNING: 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 for the first time and when the check valve or a compressor
pump/motor has been replaced.
1. Ensure the On/Off switch (A) is in the OFF position.
2. Plug the power cord into the correct branch circuit receptacle. See
Voltage and Circuit Protection under Installation.
3. Open the drain valve (counter-clockwise) fully to permit air to
escape and prevent air pressure build up in the air tank during
the break-in period.
4. Move the On/Off switch to the ON position. The compressor will
start.
5. Run the compressor for 15 minutes.
6. After 15 minutes, close the drain valve by turning clockwise.
The tank will fill to cut-out pressure and the motor will stop.
7. Compressed air will be available until it is used or bled off.

CAUTION: Risk of unsafe operation. Compressed air from the unit
may contain wa ter condensation. Do not spray un fil tered air at an
item that could be damaged by moisture. Some air op er ated tools
or de vic es may require filtered air. Read the in struc tions for the air
