POSSIBLE SOLUTION

Clean or replace.

Check beltwheel, motor pulley, crankshaft, drive belt tension and alignment. Repair or replace as required.

Relocate compressor for better air flow.

Drain existing lubricant and refill with proper lubricant. Check tubing and connections. Tighten joints or replace as required.

Drain existing lubricant and refill with proper lubricant. Drain excess lubricant.

Add lubricant to crankcase to proper level.

Drain existing lubricant and refill with proper lubricant. Run compressor for longer duty cycles.

Relocate compressor or install crankcase heater kit.

Adjust pressure switch to increase differential, if differential adjustment is provided. Install pressure switch with differential adjustment feature if differential adjustment is desired.

Check line voltage and upgrade lines as required. Contact electrician.

Intall properly sized wire or service box. Contact electrician. Ensure good contact on motor terminals or starter connections. Install proper starter overload heaters. Contact electrician. Contact power company.
