Minor carburetor adjustment may be required to 
compensate for differences in fuel, temperature, 
altitude and load.

•

Refer to the separate engine manual, packed with 
your unit, for carburetor adjustment information.

Before lubricating, repairing, or 

inspecting, disengage all clutch levers and 
stop engine. Wait until all moving parts have 
come to a complete stop. Disconnect spark 
plug wire and ground it against the engine to 
prevent unintended starting. Always wear 
safety glasses during operation or while 
performing any adjustments or repairs.

Refer to the separate engine manual packed with the
snowthrower for detailed instructions regarding all
engine-related maintenance.

If any adjustments need to be 

made to the engine while the engine is 
running (e.g. carburetor), keep clear of all 
moving parts. Be careful of muffler, engine 
and other surrounding heated surfaces.

The cams 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. The cams can be accessed beneath the 
handle panel. Use a multi-purpose automotive grease. 
See Figure 14.

The gear case is lubricated with grease at the factory 
and it does not require checking. If disassembled for 
any reason, lubricate with 2 ounces of Shell Alvania 
grease EPR00, part number 737-0168. Before 
reassembling, remove old sealant and apply new 
sealant.
