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.
Lubrication
(See Figure 11.)
WARNING: Disconnect the spark plug wire
and ground against engine before starting
lubrication or maintenance job on unit.
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
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.
Drive and Shifting Mechanism
• Lubricate at least once a season or after every 25
hours of operation. Remove rear cover. Lubricate
chains, sprockets, gears, bearings, shafts, and
shifting mechanism at least once a season. Use
engine oil or spray a lubricant. Avoid getting oil on
rubber friction wheel and aluminum drive plate.
Engine
Refer to engine manual for all engine lubrication
instructions.
WARNING: When following instructions in
separate engine manual for draining oil, be
sure to protect frame by avoiding oil
dripping into transmission parts.
