cool. Disconnect spark plug wire. Drain gasoline from fuel tank.

BEFORE STARTING ENGINE

IMPORTANT; BE VERY CAREFUL NOT TO ALLOW D/RT
TO ENTER THE ENGINE WHEN CHECKING OR ADDING
OIL OR FUEL, USE CLEAN OIL AND FUEL AND STORE IN APPROVED, CLEAN, COVERED CONTAINERS. USE CLEAN FILL FUNNELS.
For cold weather operation you should change oil for easier starting (See oil viscosity chart in the Customer Responsibilities section of this manual).
T0 change engine oil, seethe Customer Responsibilities
section in this manual.

ADD GASOLINE

• Fill fuel tank. Use fresh, clean, regular unleaded gasoline. (Use of leaded gasoline will increase carbon and lead oxide deposits and reduce valve life.)
IMPORTANT: WHEN OPERATING IN TEMPERATURES BELOW32“F(0“C), USE FRESH, CLEAN, WINTER GRADE GASOLINE TO HELP INSURE GOOD COLD WEATHER STARTING.
WARNING; Experience indicates that alcohol blended fuels
(called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while In storage. To avoid engine problems, the
fuel system should be emptied before storage of 30 days or longer. Drain the gas tank, start the engine and let it run until the fuel lines and carburetor are empty. Use fresh fuel
next season. See Storage section of this manual for
additional information. Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur.
CAUTION: Fill to within 1/2 inch of top of fuel tank to prevent spills and to allow
A
for fuel expansion. If gasoline is acci dentally spilled, move machine away from area of spill. Avoid creating any source of ignition until gasoline vapors
have disappeared.
Do not overfill. Wipe off any spilled oil or fuel. Do not store, spill or use gaso line near an open flame.

CHECK ENGINE OIL LEVEL (See Fig. 12)

The engine In your unit has been shipped, from the factory, already filled with SAE 30 summer weight oil.
With engine level, clean area around oil filler plug and remove plug.
Engine oil should be to point of overflowing when engine is level. For approximate capacity see “PRODUCT SPECIFICATIONS” on page 3 of this manual. All oil must meet A.P.I. Service Classification SF-SJ.
