MAINTENANCE
Tank
Always replace worn, cracked or damaged tanks.
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.
Never attempt to repair or modify a tank! Welding, drilling or any other
modification will weaken the tank resulting in damage from rupture or explosion.
Drain liquid from tank after each use.
