Problem
Possible Cause
Solution
Engine Starts and Runs
Rough or Engine will not
Start.
1.) Ignition switch or On/Off switch is turned off or
Throttle Lever is not in correct position.
2.) Fuel valve is turned off
3.) Out of fuel
4.) Water in fuel
5.) Old Fuel
6.) Carburetor float stuck or clogged
7.) Lever on Throttle needs to be turned up
8.) Recoil Start is not in correct position
9.)Air Filter needs to be cleaned
10.)Insufficent oil level
11.)Possible fouled spark plug or wiring boot damaged
12.) Air Tanks filled with residual air
1.) Turn ignition switch or on/off switch on
2.) Turn fuel valve on
3.) Fill fuel tank
4.) Drain fuel tank into an approved container and
refill with fresh fuel
5.) (same as #4 above)
6.) Clean the Carburetor or replaced
7.) Move throttle lever toward rabbit and not turtle
8.) Read and follow starting instructions
9.)Replace or clean air filter
10.)Add oil to proper level
11.)Check spark plug for spark
12.)Open tank valves and then start the unit
Engine Shuts Down During
Operation
1.) Out of fuel
2.) Low oil level
3.) Debris in carburetor
4.) Possible faulty ignition
system or spark plug
5.) Fault in engine
1.) Fill fuel tank
2.) Add oil to proper level
3.) Have carburetor cleaned by
service dealer
4.) Check spark plug for spark
5.) Contact customer service at 1-877-601-2823
Low Discharge Pressure
1.) Air leaks
2.) Leaking valves
3.) Restricted air intake
4.) Slipping belt
5.) Blown head or seals in
pump
6.) Regulator/unloader valve
needs adjusting
7.) Low compression
1.) Listen for escaping air. Apply soap solution to fittings
to see if the bubbles appear
2.) Replace ACM or regulator/unloader valve
3.) Clean the air filter element
4.) Remove belt guard and tighten belt (see pg. 8)
5.) Replace V pump (no rebuild kits)
6.) Adjust regulator/unloader valve
7.) Replace pump (no rebuild kit)
Overheating Pump
1.) Poor ventilation
2.) Dirty cooling surfaces
3.) Blown cylinder head on
pump
4.) Low oil in pump
1.) Move compressor to a well ventilated area
2.) Clean all cooling surfaces including air filers on
engine
and pump
3.) Both pump heads should be pulling air in to cool
pump. If
one or both heads are blowing air out, pump must
be replaced
4.) Check oil level thru site glass at base of pump. Add
oil as needed. Use SAE 30 in compressor pump
Excessive Belt Wear
1.) Pulley is out of alignment
2.) Belt too loose or too tight
3.) Pulley wobbles
1.) Re-align pulley
2.) Adjust belt tension Check belt for wear. Replace
belt if needed
3.) Check for worn or bent crankshaft, worn or loose
keyway. Check shaft bore in
pulley for wear
Engine Stalls
1.) Low Oil levels
2.) Engine shuts down when
tank pressure reaches
maximum capacity
1.) Check oil level in engine and
pump. (use SAE 30 oil in
pump and engine)
2.) Throttle control needs to be
adjusted to higher RPM.
