Lubrication

Gear (Hex) Shaft

Once a season, lubricate the hex shaft with a penetrat-

ing oil, but not grease. Refer to Figure 17.

Wheels

At least once a season, remove both wheels. Clean and

coat the axles with a multipurpose automotive grease

before reinstalling wheels.

Auger Shaft

At least once a season, remove the shear pins on auger

shaft. Spray lubricant inside shaft, around the spacers.

Also lubricate the flange bearings found at either end of

the shaft. See Figure 24.

Gear Case

The auger gear case has been filled with grease at

the factory. If disassembled for any reason, lubricate

with two ounces of grease (Part Number 737-0168).

Before reassembling, remove old sealant and apply new

sealant.

NOTE: Do not overfill the gear case. Damage to the

seals could result. Be sure the vent plug is free of

grease in order to relieve pressure.

bearings, shafts, and shifting mechanism at least once

a season. Use engine oil or a spray lubricant. Avoid

getting oil on rubber friction wheel and aluminum drive

plate.

unit for all engine lubrication instructions.

Drive/Auger Control Lock

The cam on the ends of the control rods which interlock

the drive and auger controls must be lubricated at least

once a season or every 25 hours of operation using

a multi-purpose automotive grease. The cam can be

accessed beneath handle panel.
