The grease must have adequate base oil viscosity with one of the following ratings:

●ISO VG 150 (135–165 cSt at 40°C or 709–871 SUS at 100°F)

●ISO VG 220 (198–242 cSt at 40°C or 1047–1283 SUS at 100°F)

●An SAE 40 rating is also acceptable as long as the cSt or SUS values are within the specified ranges.

Pump the grease gun slowly, permitting only two strokes.

2.Clean the AC drive cooling fins:

a.Remove the AC drive box cover.

b.Blow the fins clean using compressed air at a pressure of 60 – 90 psi or canned compressed air. Use care to avoid damaging cooling fan or other components.

NOTE: No amount of visible foreign matter should be allowed to accumulate on the fins or the finger guard.

3.Use the following procedures to determine if belts require replacement or adjustment. Call a qualified service technician in either case.

a.Check belts for uneven wear and frayed edges.

b.After disconnecting power to the washer- extractor and removing all panels necessary for access to the drive belt, use one of the following methods to verify that belts are properly tensioned:

●Tension Gauge. Belt tension measurements should be taken as close to the center of the belt span as possible. Measurements can be performed with the Belt Tension Checker. Make adjustments for the motor pulley diameter and belt type on the machine.

If belt tension adjustment is required, loosen motor mounting bolts and slide motor along motor plate to change the belt tension. Retighten motor mounting bolts before verifying belt tension.

Maintenance

●Deflection. Refer to Figure 4. Loosen motor mounting bolts and slide motor along motor plate to change belt span length. Belt tension measurements should be taken as close to the center of the belt span as possible. For every inch of belt span length, the belt should deflect 1/64 of an inch, or 0.40 millimeter, with an exerted force of 5.25 pounds for a new belt or

3.5 pounds for a used belt. A belt with a span length of 20 inches should deflect 20/64 of an inch, or 7.8 millimeters. The belt(s) should be as loose as possible without allowing slippage during peak load condition. An initial (run-in) force of 7 lbs. should be used to set the belt tension. An operating (normal) force of 5 lbs. should be used after the washer-extractor has been operated for a few hours.
