EVERY 90 DAYS OR 500 HOURS MAINTENANCE
1. Change crankcase oil. Use only Champlub recip lubricant.
2. Check entire system for air leakage around fittings, connections, and gaskets, using soap solution
and brush.
3. Tighten nuts and cap screws as required.
4.
Check and clean compressor valves as required. Replace when worn or damaged parts.
CAUTION
Valves must be replaced in original position. Valve gaskets should be replaced each time
valves are serviced.
5. Pull ring on all pressure relief valves to assure proper operation.
GENERAL MAINTENANCE NOTES
PRESSURE RELIEF VALVE: The pressure relief valve is an automatic pop valve. Each valve is properly
adjusted for the maximum pressure of the unit on which it is installed. If it should pop, it will be
necessary to drain all the air out of the tank in order to reseat properly, or drop pressure in line. Do
not readjust.
PRESSURE SWITCH: The pressure switch is automatic and will start compressor at the low pressure
and stop when the maximum pressure is reached. It is adjusted to start and stop compressor at the
proper pressure for the unit on which it is installed. Do not readjust.
BELTS: Drive belts must be kept tight enough to prevent slipping. If belts slip or squeak, see V-belt
maintenance in preceding section.
CAUTION
If belts are too tight, overload will be put on motor and motor bearings.
COMPRESSOR VALVES: If compressor fails to pump air or seems slow in filling up tank, disconnect
unit from power source and remove valves and clean thoroughly, using compressed air and a soft
wire brush. After cleaning exceptional care must be taken that all parts are replaced in exactly the
same position and all joints must be tight or the compressor will not function properly. See
instructions below for manifold assembly. When all valves are replaced and connections tight,
close hand valve at tank outlet for final test. Valve gaskets should be replaced each time valves
are removed from pump.
TYPICAL MANIFOLD ASSEMBLY
WHEN INSTALLING HEAD UNLOADER MAINFOLD
ASSEMBLY, BE CERTAIN THAT THE ACTUATING
CLAW PROTRUDES 3/16” BELOW THE BOTTOM OF
THE MANIFOLD. CLAW MUST BE POSITIONED SO
THAT IT WILL ENTER TWO SLOTS IN THE
COMPRESSOR VALVE. FAILURE TO FOLLOW THIS
PROCEDURE WILL RESULT IN AN INOPERATIVE
HEAD UNLOADER.
