ENGINE MAINTENANCE
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.
