ASSEMBLING THE COMPRESSOR

1.  Unpack the air compressor. Inspect the unit for damage. If the unit has been damaged 

in transit, contact the carrier and complete a damage claim. Do this immediately 

because there are time limitations to damage claims. 

The carton should contain:

•

air compressor

•

operator and parts manuals

2.  Check the compressor’s serial label to ensure that you have received the model 

ordered, and that it has the required pressure rating for its intended use.

3.  Locate the compressor according to the following guidelines:

a.   For optimum performance, locate the compressor close to the power panel, as 

specified in ELECTRICAL POWER REQUIREMENTS, and as close as possible 

to the place where the air will be used. This ensures maximum power to the 

compressor and maximum air  pressure to the tool. If  both of these conditions  

cannot be met, it is better to locate the compressor close to the power panel, 

and use a longer air hose to reach the usage area.

b.  The flywheel side of the compressor must be at least 12 inches (31 cm) from any 

wall or obstruction, in a clean, well-ventilated area, to ensure sufficient air 

 flow and cooling.

c.  In cold climates, locate the compressors in a heated building when not in use. 

This will reduce problems with lubrication, motor starting and freezing of water 

condensation.

d.  Remove the compressor from the shipping pallet and place it on the floor or a 

hard, level surface. The compressor must be level to ensure proper 

 lubrication of the pump and good drainage of the moisture in the tank.

Risk of injury: The shipping pallet is not designed as a base for 

an operating compressor. Operating the compressor while it is on the pallet will 

void your warranty.

e.   To prevent damage to tank and pump, the tank must be shimmed so the pump 

is level within 1/8” per lineal foot maximum to distribute oil properly. Fasten to 

floor and NEVER force tank feet to floor without shims when tightening. We also 

recommend the use of vibration pads (094-0137) under tank feet (C).

4.  Connect an air hose (not included) to the 

compressor.

WARNING

air is used and the pressure level in the tank drops to the kick–in pressure, the 

pressure switch restarts the motor automatically, without warning and the pump 

resumes compressing air.

The 

air line outlet 

(see

 E

). Connect 1/4” NPT air hose to this outlet.
