6. Sight Gauge/Dipstick
Prior to daily operation, make a habit of checking the oil level of the compressor pump and
engine. Our belt-driven air compressors are equipped with a sight gauge to make the daily
task of checking the oil level easier. Always maintain the oil level to read 2/3 full on the
sight gauge. Engine oil level should be maintained to the top threads of either oil fill port
with engine in a level position.
7. Check Valve
The air compressor is built with a check valve to seal off and maintain tank pressure after
the top end pressure setting of pilot valve or pressure switch is reached. The check valve
works in conjunction with the pressure switch relief valve to provide a loadless start for the
compressor system. If the compressor has a mysterious leak after stopping that cannot be
traced elsewhere, the check valve may require servicing/replacing.
8. Breather/Oil Fill Plug
All reciprocating air compressor pumps are built with a crankcase vent to relieve the
pressure that is created by the downward movement of the piston in the pump cylinder.
Our belt-drive units vent through the oil-fill plug. Never operate the air compressor without
the dipstick or oil-fill plug.
9. Automatic-Idle Control
This gas-powered air compressor is built with an engine idle control kit that automatically
decreases the engine speed when the top end pressure setting of the pilot unloader valve is
reached. The top RPM setting of the engine is factory set for maximum performance and
service life. Do not alter the factory top RPM setting. The engine idle speed is factory set
and controlled by a black plastic Philips head screw on the carburetor. A slight increase to
the idle speed setting may be required when operating in colder temperatures. Turn screw
clockwise in 1/4-turn increments to increase the idle speed. If the idle speed setting is too
low, premature fouling of spark plug will occur.
10. Cold-Start Valve
Our belt-driven portable units have a manual drain valve installed on the pump aftercooler
to assist with cold weather starting. Open drain valve and allow the motor and pump to run
unloaded for a minute to warm up. Close the drain and repeat the procedure if the motor or
engine continue to struggle.
11. Schmidt Belt-Tightening Device
The gas-powered belt-driven portable air compressor has a
unique system for maintaining proper belt tension. To
maintain proper belt tension, first loosen the bolts on the
bracket between engine and mounting plate. Then simply
loosen the 1/2 in. locknuts (only until the washers beneath
spin freely) that secure the engine to mounting plate.
Rotate the 3/4 in. fine thread bolt located on engine end
of plate clockwise until the desired belt tension is reached.
Retighten the 1/2 in. locknuts and bracket bolts to
maintain the adjusted belt tension.
12. Vibration Dampener(s)
The rubber pads installed beneath the portable tank assembly are very important to the
proper operation of the air compressor. They provide protection from vibration that left
unchecked could cause damage to many system components.
