The engine on your snow thrower has been shipped, from the factory, already filled with oil.

1.Check engine oil with snow thrower on level ground.

2.Remove oil fill cap/dipstick and wipe clean, reinsert the dipstick and screw tight, wait for a few seconds, remove and read oil level. If necessary, add oil until “FULL” mark on dipstick is reached. Do not overfill.

•To change engine oil, see “TO CHANGE ENGINE OIL” in the Maintenance section of this manual.

ADD GASOLINE (See Fig. 17)

•Fill fuel tank to bottom of tank filler neck. Do not over- fill. Use fresh, clean, regular unleaded gasoline with a minimum of 87 octane. Do not mix oil with gasoline. Purchase fuel in quantities that can be used within 30

days to assure fuel freshness. 11
