SyMptoM
Insufficient pressure at
point of use
Tank does not hold
pressure when
compressor is unloaded
Excessive belt wear
Excessive discharge air
temperature
Tank pressure builds up
slowly
Tank pressure builds up
quickly on compressor
Compressor continues
to build up pressure
after unloading pressure
is reached
Engine stalls
Gasoline engine will not
start
ASME safety valve pops
open while compressor
is running

CauSe
1� Leaks or restriction
2. Restricted air intake
3� Slipping belts
4� Service hose or pipe too
small
5. Excessive air requirement
6. Broken valve
Air leak in system
1. Pulley out of alignment
2. Belts too tight
3. Belts too loose
4. Pulley or flywheel wobble
5� Damage in belt groove of
pulley or flywheel
1� Dirty cooling surfaces
2. Poor ventilation
3. Blown head gasket
4. Restricted air intake
5� Worn valves
1� Dirty air filter
2. Blown cylinder head
gasket
3� Worn or broken intake or
discharge valves
4. Air leaks
5� Loose belts
6� Speed too slow
1� Water in tank
2� Speed too fast
1� Severe air leak in pilot
unloader valve
2. Restriction in unloader
lines
Toggle lever on pilot
unloader valve in loaded
position
Low engine oil� Some
engines equipped with low-
oil shutdown
1� Wrong unloader valve
setting
2. Defective ASME safety
valve
Solution
1. Check for leaks or restriction in hose or piping. Repair or replace.
2� Clean or replace air filter element�
3� Tighten belts, See "Maintenance" section�
4. Replace with larger hose or pipe.
5� Limit air usage to compressor capacity by using fewer or smaller
tools�
6. Replace reed valve assembly.
Locate and repair leak�
Never attempt to repair or modify a tank
1. Realign motor pulley with compressor flywheel.
2. Adjust tension. See "Maintenance" section.
3. Adjust tension. See "Maintenance" section.
4� Check for worn crankshaft, keyway or pulley bore, resulting from
running with loose pulleys� Check for bent crankshaft�
5. File smooth or replace.
1� Clean cooling surfaces of cylinder, intercooler and discharge tube�
2� Improve ventilation or relocate compressor�
3. Replace head gasket.
4� Clean or replace air filter element�
5. Replace valve plate assembly.
1� Clean or replace filter element�
2� Install new gasket�
3� Install new valve plate assembly
4� Tighten joints
5� Tighten belts� See "Maintenance" section
6. Check speed. See "Performance" chart
1. Drain tank. (This should be done DAILY).
2� Check speed� See specifications in replacement parts list�
1� Check all fittings and lines and replace those which leak�
2. Remove cause of restriction.
Flip toggle level up into the unload position.
Add oil to proper level.
1. Adjust to lower pressure (175 maximum psi for two-stage unit or
125 psi for single stage unit)� See Operation section�
2. Replace valve.
