EMISSIONS CONTROL STATEMENT

Maintenance, replacement, or repair of the emissions control
devices and systems may be performed by any non-road en-
gine 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 11). 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.
