1. Reduce air demand or use a compressor with more capacity.
2. Listen for escaping air. Applx. soap solution to all fittings
and connections_lubbles

Tighten or replace leaking fittings or connections.
3. Clean the air filter element.
4. Replace anygaskets

compressor pulley
2. Lack of oil in crankcase
3. Worn connecting rod
4. Worn piston pin bores
5. Piston hitting the valve

2. Checkfor proper oil level; if low, checkfor possible damage
to bearings. Dire/oil can cause excessive wear.
3. Replaceconnecting rod. Maintain oil level and changeoil
mo_ frequently.
4. Remove piston assembliesfrom the compressorand inspect
for excesswear. Replaceexcessively worn p_on pin or
pistons,as required. Maintain oil level and change oil more

5. Remove the compressorhead and valve plate and inspectfor
carbon depositsor other foreign matter on top of piston.
Replacehead and valve plate usingnew gasket. See
