Emissions Control Statement
Maintenance, replacement, or repair of the emissions
control devices and systems may be performed by any non-
road engine repair establishment or individual. However,
to obtain "no charge" emissions control service, the work
must be performed by a factory authorized dealer. See the
Emissions Warranty.
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 snowthrower is not used for fifty hours.
Use a clean, high quality detergent oil. Fill the crankcase
to FULL line on dipstick (A, Figure 13). 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 snowthrower so that the oil drain plug
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 recommended motor oil.
