Warning: Do not operate the compressor with the fan or belt guard removed. Exposed fan and belts can cause injury to personnel.

DANGER: Before performing any maintenance be sure the electrical supply has been cut off, locked and tagged and that all pressure has been relieved from the compressed air system.

Disconnect the power, lock out and tag out, and allow all pressure to be relieved.

Inspect for any fraying or cracking. If found replace the belts.

Check the tension. The deflection should be about 1/64” per inch of span between the sheaves with about 4-6 pounds of downward force.

To adjust the tension, loosen the bolts holding the motor to the slide base and using the take-up bolts move the motor until the belts are tight per number 4 above, then retighten the motor bolts.

Replace the belt guard and return the compressor to service.
