1. Clean dust and foreign matter from cylinder head, motor, fan blade, air lines, intercooler and tank.

2. Remove and clean intake air filters.

WARNING! Do not exceed 15 PSIG nozzle pressure when cleaning element parts with compressed air. Do not direct compressed air against human skin. Serious injury could result. Never wash elements in fuel oil, gasoline or flammable solvent.

3. Check V-belts for tightness. The V-belts must be tight enough to transmit the necessary power to the compressor. Adjust the V-belts as follows:

a. Remove bolts and guard to access compressor drive.

b. Loosen mounting hardware which secures motor to base. Slide motor within slots of baseplate to desired position.

c. Apply pressure with finger to one belt at midpoint span. Tension is correct if top of belt aligns with bottom of adjacent belt. Make further adjustments if necessary.

d. Check the alignment of pulleys. Adjust if necessary.

e. Tighten mounting hardware to secure motor on base.
