OPERATING INSTRUCTIONS
IMPORTANT: Check motor rotation before operating the compressor.
All lubricated compressor pumps discharge some condensed water and oil with the compressed air. Install
appropriate water/oil removal equipment and controls as necessary for the intended application.
Guarding
All moving parts must be guarded. All electrical covers must be installed before turning on the power.
Recommended Break-In Period
The compressor should be run continuously for one hour to allow proper seating of the piston rings.
1. Open drain cock completely and run the compressor for 60 minutes.
2. Turn off the compressor and close drain cock. The compressor is now ready for use.
Pressure Switch, Start - Stop
NOTE: This compressor has a maximum operating
pressure of 175 psi. Do not alter pressure settings on
control components above this limit.
The compressor unit starts and stops based on preset
pressure switch settings of 145 psi cut-in and 175 psi
cut-out. The pressure switch contains an unloader
which is a small valve that vents air to allow the motor
to start easily (see Figure 9).
The unloader valve on the pressure switch should hiss
for a short period of time when the compressor shuts
off. This relieves the head and the exhaust tubing of
any pressure and allows the compressor to start under
no load. Because compressors have high starting
torque the unloader is necessary for proper starting of
the compressor.
The check valve is a one way valve that keeps the air in the tank when the unit shuts off. The easiest way to
determine if the check valve is working properly is to make sure that the pressure switch unloader quits hissing
after the compressor shuts off. The hissing should last for several seconds and then quit.
Crankcase Breather
During severe operating conditions or initial start-up, some oil may
accumulate at the crankcase breather opening. This is normal and
will diminish as the pump accumulates run time and the piston rings
become fully seated.
Draining Tank
Condensation must be drained from the tank daily. On Shop Air
Series models use manual tank drain (see Figure 10). Refer to
instructions provided with the automatic drain. Tire and Lube Series
models include an automatic tank drain which must be installed (see
Figure 11). Refer to instructions provided with the automatic drain.
12
Failure to install appropriate water/oil removal equipment may result in
damage to machinery or workpiece.
The belt guard provided must be installed before operating the unit.
