Check Gear Reducer Oil Level

Every day, check the oil level in the sight glass (SG) on the gear reducer, with the motor running. Oil level (with motor running) should fall between top and bottom of the sight glass (SG). Open the fill cap (FC) and fill the gear reducer oil reservoir as required with Graco 288414 Oil (package includes twelve 1 quart bottles). Do not overfill. See FIG. 8.

Gear Box and Drive Lubrication

Replace the gear box lubricant after a break-in period of 200,000-300,000 cycles. Order 288414 Replacement Oil.

Following the break-in period, replace the gear box lubri- cant once a year.

See FIG. 9. Every 6 months, lubricate the wrist pin bear- ing (7a) on the connecting rod with 1 shot (1 cc) of 107411 Grease or equivalent, using grease zerk (GZ). Replace both wrist pin bearings annually. Order Wrist Pin Replacement Kit 255216. Lubricate the crank pin bearing (X) annually, using grease zerk (GZ).

NOTE: A faint clicking may be heard while the motor is running. This is normal and is due to necessary clear- ances between the coupler (28), motor shaft, and motor key. If the intensity increases significantly over time, it could indicate the coupler is wearing and should be replaced. Do not open the gear reducer. The gear reducer is not field serviceable beyond the maintenance recommended in this manual
