ENGINE
Check Crankcase Oil Level before starting engine and after
each 5 hours of continuous use (see Figure 29). Add proper
motor oil as required.
NOTE: Overfilling the engine can affect performance.
Tighten the oil fill cap securely to prevent leakage.
Change Oil every 25 hours of operation or at least once a
year, even if the snowthrower is not used for twenty−five
hours. Use a clean, high quality detergent oil. Fill the crank
case to FULL line on dipstick (see Figure 29). 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.
To Drain Oil − Position snowthrower so that the oil drain plug
is lowest point on engine. Remove oil drain plug and oil fill cap
and drain oil into a suitable container (Figure 30).
NOTE: Oil will drain more freely when warm.
Replace oil drain plug and tighten securely. Refill crank case
with proper motor oil or as indicated in the preceding
paragraphs of this section.
