NOTE: Once the engine pulley has been moved from its factory set location, the grooves of the flywheel and pulley must be aligned to within 1/16" to prevent excessive belt wear. Verify the alignment by performing the follow- ing Pulley and Flywheel - Alignment.

Motor Pulley/Flywheel Alignment

NOTE: Once the motor pulley has been moved from its factory set location, the grooves of the flywheel and pulley must be aligned to within 1/16" to prevent excessive belt wear.

The air compressor flywheel and motor pulley must be in-line (in the same plane) within 1/16" to assure belt retention within flywheel belt grooves. To check alignment, perform the following steps:

1.Turn air compressor off, lock out the power supply, and relieve all air pressure from the air tank.

2.Remove belt guard.

3.Place a straightedge against the outside of the flywheel and the motor drive pulley.

4.Measure the distance between the edge of the belt and the straightedge at points A1 and A2 in figure. The difference between measurements should be no more than 1/16".

5.If the difference is greater than 1/16"

loosen the set screw holding the motor drive pulley to the shaft and adjust the pulley’s position on the shaft until the A1 and A2 measurements are within 1/16" of each other.

6.Tighten the motor drive pulley set screw. See Parts manual for torque specifications.

7.Visually inspect the motor drive pulley to verify that it is perpendicular to the drive motor shaft. Points B1 and B2 of Figure should appear to be equal. If they are not, loosen the setscrew of the motor drive pulley and equalize B1 and B2, using care not to disturb the belt alignment performed in step 2.

8.Retighten the motor drive pulley setscrew. See Parts manual for torque specifications.

Air Compressor Pump Intake and Exhaust Valves

Once a year have a Trained Service Technician check the air compressor pump intake and exhaust valves.

Inspect Air Lines and Fittings for Leaks

1.Turn air compressor off, lock out the power supply, and relieve all air pressure from the air tank.

2.Apply a soap solution to all air line fittings and connections/piping.

3.Correct any leaks found.

IMPORTANT: Even minor leaks can cause the air compressor to overwork, resulting in premature breakdown or inadequate performance.

Air compressor Head Bolts - Torquing

The air compressor pump head bolts should be kept properly torqued. Check the torques of the head bolts after the first five hours of operation. Retighten if necessary. See Parts manual for torque specifications
