Check Crankcase Oil Level
-
Before starting engine and after each 8
hours of continuous use. Add the recommended motor oil as required.
NOTE: Over filling the engine can affect performance. Tighten
the oil fill cap securely to prevent leakage.
Change Oil
-
Every 50 hours of operation or at least once a year, even if
the snow thrower is not used for fifty hours. Use a clean, high quality
detergent oil. Fill the crankcase to FULL line on dipstick (A
A, Figure 19). Be
sure original container is marked: A.P.I. service “SF” or higher. Do not use
SAE10W40 oil (as it may not provide proper lubrication).
See Chart for
oil recommendations
.
Drain Oil
– Position snow thrower so that the oil drain plug (A
A, Figure
20) is lowest point on engine. When the engine is warm, remove oil drain
plug and oil fill cap and drain oil into a suitable container.
Replace oil drain plug and tighten securely. Refill crankcase with the rec-
ommended motor oil.
