SERVICE AND MAINTENANCE

Removing Snow from the Engine

After each use, remove snow from the following areas:

Oil Fill Cap & Dipstick

Fuel Cap

Recoil Starter/Flywheel Screen

Linkage

Guards

Spark Plug Connection (if visible)

Electric Starter Switch Box, if present (see the equipment

Operator’s Manual instructions).

proper location of fuel cap and control lever.

Removing snow will ease operation of the recoil starter and

reduce the risk of water contamination when opening the fuel

cap.
