1. Air Filter.
The air filter keeps dirt and
debris from entering the compressor
pump.
2. Dipstick. The dipstick measures the
oil level in the compressor pump (See
Figure 3).
3. ASME Safety Valve. This valve auto-
matically releases air if the tank pres-
sure exceeds the preset maximum.
4. Regulator Knob. This knob controls
air pressure to an air operated tool or
paint spray gun. Turning the knob
clockwise increases air pressure at
the outlet. Turning counterclockwise
will lower air pressure at the outlet.
Fully counterclockwise will shut off
the flow of air completely (See Figure
4).
5. Tank Drain Valve. The tank drain
valve allows moisture to be removed
from the tank. Note that each tank
has its own tank drain valve.
6. Unloader. The unloader controls the
engine rpm. When loaded, the engine
will run at maximum operating speed
and air will enter the tank. When
unloaded, the engine will slow to an
idle and air will vent to atmosphere.
7. Belt Guard. The belt guard encloses
the pulleys and drive belt. It protects
the user from moving parts and
directs cooling air to the compressor
pump
