GUIDE TO MAINTENANCE
For Service contact an authorized Champion distributor. All requests should include model number
and serial number. To obtain reliable and satisfactory service, this unit requires a consistent
preventive maintenance schedule. Maintenance schedule form is included to aid in keeping the
proper records.
WARNING
Before performing any maintenance function, switch main disconnect switch to "off" position
to assure no power is entering unit. "Lock Out" or "Tag Out" all sources of power. Be sure all
air pressure in unit is relieved. Failure to do this may result in injury or equipment damage.
DAILY MAINTENANCE
1. Check oil level of compressor. Add Champlub recip lubricant as required. See “Compressor Oil
Specifications” Section. NOTE: Do not mix oil type, weight, or brands.
2. Drain moisture from tank by opening tank drain cock located in bottom of tank. Do not open drain
valve if tank pressure exceeds 25 PSIG.
3. Turn off compressor at the end of each day's operation. Turn off power supply at wall switch.
WEEKLY MAINTENANCE
1. Clean dust and foreign matter from cylinder head, motor, fan blade, air lines, intercooler and tank.
2. Remove and clean intake air filters.
WARNING
Do not exceed 15 PSIG nozzle pressure when cleaning element parts with compressed air. Do
not direct compressed air against human skin. Serious injury could result. Never wash
elements in fuel oil, gasoline or flammable solvent.
3. Check V-belts for tightness. The V-belts must be tight enough to transmit the necessary power to
the compressor. Adjust the V-belts as follows:
Remove bolts and guard to access compressor drive.
Loosen mounting hardware which secures motor to base. Slide motor within slots of baseplate to
desired position.
Apply pressure with finger to one belt at midpoint span. Tension is correct if top of belt aligns with
bottom of adjacent belt. Make further adjustments if necessary.
Check the alignment of pulleys. Adjust if necessary.
Tighten mounting hardware to secure motor on base.
Re-install guard and secure bolts.
WARNING
Never operate unit without belt guard in place. Removal will expose rotating parts which can
cause injury or equipment damage.
