Maintenance

Release all pressure from the system
before attempting to install, service,
relocate or perform any maintenance.
In order to maintain efficient operation of the
compressor system, check the air filter, oil level and
gasoline level before each use. The ASME safety valve should
also be checked weekly. Pull ring on safety valve and allow the
ring to snap back to normal position. This valve automatically
releases air if the tank pressure exceeds the preset maximum.
If air leaks after the ring has been released, or the valve is stuck
and cannot be actuated by the ring, the ASME safety valve must
be replaced.
Do not attempt to tamper with the ASME
safety valve.
With engine OFF, clean debris from engine, flywheel, tank, air
lines and pump cooling fins.
TANK
Never attempt to repair or modify a
tank! Welding, drilling or any other
modifi cation will weaken the tank resulting in damage
from rupture or explosion. Always replace worn, cracked or
damaged tanks.
Drain liquid from tank daily.
The tank should be carefully inspected at a minimum of once
a year. Look for cracks forming near the welds. If a crack is
detected, remove pressure from tank immediately and replace.
PUMP DRIVE BELT
Belt stretch is a result of normal use. When properly adjusted,
the belt deflects about 1/2 inch with five pounds of force applied
midway between the engine pulley and pump pulley.
To adjust pump belt tension:
1. Remove belt guards.
2. Loosen the four fasteners holding the pump to the
baseplate.
3. Shift the pump in the proper direction using the adjustment
screw below the pump on the frame. The belt must be
properly aligned when adjustment is made.
4. To align belt, lay a straight edge against the face of the pump
pulley, touching the rim at two places.
5. Adjust engine pulley so that the belt runs parallel to the
straight edge.
6. Tighten four fasteners holding the pump to the baseplate.
7. Recheck tension and alignment. If correct, reinstall belt
guards.

ALTERNATOR DRIVE BELT
The alternator uses a multi-V drive belt transmitting a
significant amount of power. Belt tension is critical to belt life.
New belts will stretch after installation and use. When properly
adjusted, the belt deflects 1/4 inch with firm pressure applied
midway between the engine pulley and the alternator pulley.
To adjust alternator belt tension:
1. Remove belt guard.
2. Loosen the 4 bolts holding the engine to the base plate.
3. Use the adjustment screw located below the engine on the
frame to obtain the proper tension. Make sure the pump
belt is not over tightened. The belt must be properly aligned
when the adjustment is made.
4. To align belt, lay a straight edge against the face of the
alternator pulley, touching the rim at two places. The
straight edge should be parallel with the belt.
5. Adjust alternator or engine pulley so that the belt runs
parallel to the straight edge.
6. The pulleys are attached to the shafts using tapered
bushings. The two set-screws must be removed and one
reinserted into the hole with threads on the inner half.
Tighten this screw to press the pulley and bushing apart.
7. Once the bushing is moved to the correct position, move the
two set-screws back to their original locations in the holes
with threads on the outer half and tighten to 175 in-lbs.
8. Recheck tension and alignment. If correct, reinstall belt
guard.
INFREQUENT USAGE
If the unit is used infrequently, starting difficulty may occur. To
help prevent this, the engine should be run for approximately 30
minutes per week.
STORAGE
If the unit is not to be used for extended periods of time, the
following pre-storage procedures should be performed:
1. Make sure engine oil is filled to the proper level.
2. Drain moisture from air tanks.
3. Drain all fuel from the tank, lines, carburetor and fuel valve.
4. Remove the spark plug, and pour approximately one
teaspoon of oil into the spark plug hole.
5. Pull the starter cord several times to spread the oil
throughout the cylinder.
6. Slowly pull the starter cord, until resistance is felt.
This indicates that the piston is moving upward on the
compression cycle, and the intake and exhaust valves are
closed. (The piston pushes a small amount of air from the
spark plug hole on compression.)
