Carburetor

WARNING: If any adjustments are made to the engine while the engine is running (e.g. carburetor), keep clear of all moving parts. Be careful of heated surfaces and mufflers.

Minor carburetor adjustments may be required to compensate for differences in fuel temperature, altitude and load. Refer to the engine manual for instructions.

disconnected, make sure, while reassembling, to route the cable under the drive shaft and the axle before reconnecting to the support bracket.

IMPORTANT: Keep all grease and oil off of the rubber friction wheel and aluminum drive plate.

Gear Box

•The worm gear box has been filled with grease at the factory. If disassembled for any reason, lubricate with 1.5 ounces of Shell Alvania grease EPR00 (part number 737-0168). Before reassembling, remove old sealant and apply Loctite 5699 or equivalent.

WARNING: Do not overfill the gear box; or damage to the seals could result. Be sure the vent plug is free of grease in order to relieve pressure.

Wheels

•Oil or spray lubricant into wheel bearings at least once a season. Remove wheels, clean and coat axles with a multi-purpose automotive grease.

Auger Shaft

•Lubricate auger shaft at least once a season. Also lubricate the auger bearings at least once a season. Remove shear bolts on auger shaft. Oil or spray lubricant inside shaft.

Hex Shaft

•Lubricate the hex shaft with Belray 6-in-1 grease (available at automotive stores, or order by part number 737-0170) at least once a season or after every 25 hours of operation. If for any reason, the transmission was disassembled and the drive cable
