Operating Instructions
Check belt tension every 3 months.
Adjust belt tension to allow 3/8 to 1/2"
deflection with normal thumb pressure.
Also, align belts using a straight edge
against the face of the flywheel and
touching the rim on both sides of the
Operation
Check Safety Valve
Drain Tank (See Fig. 6)
Check Oil Level*
Check Air Filter
Clean unit components
Check Belt Tightness
Change Oil (See Fig. 5)
*If oil level is difficult to see, use additional light or clean sight gauge (refer to Figure 5).

face. The belts should be parallel to this
straight edge (See Figure 8). Dimension
A should be the same as B and C to
ensure proper alignment of the belts.
Slots in the bed-plate make it easy to
slide the motor back and forth to adjust
belt tension.

Corrective Action
1. Check with voltmeter, check overload relay in magnetic
starter or reset switch on motor. If overload or reset switch
trips repeatedly, find and correct the cause. See next item
2. Replace motor
3. Replace check valve or unloader valve
4. Repair or replace pressure switch
1. Adjust or replace
2. Clean or replace faulty valve
3. Be sure that fuses and heaters are rated properly
4. Replace motor
1. Tighten
2. Check for damage to bearings, replenish oil
3. Shim and tighten
Pipe air intake to less humid air source. Run pump continu-
ously for one hour
1. Diagnose oil contamination problems by testing the dis-
charge air or measuring oil consumption from the
crankcase
2. Clean or replace air filter
3. Drain oil. Refill with oil of proper viscosity
4. Replace rings
5. Tighten bolts, replace gaskets or o-rings
