SPARK ARRESTOR NOTE
NOTE: For users on U.S. Forest Land and in the states of California, Maine,
Oregon and Washington. All U.S. Forest Land and the state of California (Public
Resources Codes 4442 and 4443), Oregon and Washington require, by law that
certain internal combustion engines operated on forest brush and/or grass-covered
areas be equipped with a spark arrestor, maintained in effective working order, or
the engine be constructed, equipped and maintained for the prevention of fire.
Check with your state or local authorities for regulations pertaining to these
requirements. Failure to follow these requirements could subject you to liability or
a fine. This unit is factory equipped with a spark arrestor. If it requires
replacement, ask your LOCAL SERVICE DEALER to install the Accessory Part
#753=05245 Muffler Assembly.
All information, illustrations, and specifications in this manual are based on the

WARNING: OVERFILLING OIL CRANKCASE MAY CAUSE
SERIOUS PERSONAL INJURY. Check and maintain the proper oil
level in the crankcase; it is important and cannot be
overemphasized. Check the oil before each use and change it as
needed. See Changing the Oil.
RECOMMENDED OiL TYPE
Using the proper type and weight of oil in the crankcase is extremely important.
Check the oil before each use and change the oil regularly. Failure to use the
correct oil, or using dirty oil, can cause premature engine wear and failure.

RECOMMENDED FUEL TYPE
Old fuel is the primary reason for Fig. 6
improper unit performance. Be
sure to use fresh, clean, unleaded gasoline.
NOTE: Dispose of the old gasoline in accordance to Federal, State and

Definition of Blended Fuels
Today's fuels are often a blend of gasoline and oxygenates such as ethanol,
methanol or MTBE (ether). Alcohol-blended fuel absorbs water. As little as 1%
water in the fuel can make fuel and oil separate or form acids when stored.
Use fresh fuel (less than 60 days old), when using alcohol-blended fuel.
Using Blended Fuels
If choosing to use a blended fuel, or its use is unavoidable, follow
recommended precautions:
• Always use fresh unleaded gasoline
• Use the fuel additive STA-BIL® or an equivalent
• Drain tank and run the engine dry before storing unit

The use of fuel additives, such as STA-BIL® Gas Stabilizer or an equivalent, will
inhibit corrosion and minimize the formation of gum deposits. Using a fuel additive
can keep fuel from forming harmful deposits in the carburetor for up to six (6)
months. Add 0.8 oz.(23 ml.)of fuel additive per gallon of fuel according to the
instructions on the fuel additive container. NEVER add fuel additives directly to the
unit's gas tank.

-- i_ CAUTION" Wear gloves to prevent injury when handling the unit.
For a new engine, change the oil
after the first 10 hours of
operation. Change the oil while
the engine is still warm. The oil will
flow freely and carry away more
impurities.
1. Remove the oil fill plug.
2. Pour the oil out of the oil fill
hole and into a container by
tipping the unit to a vertical
position (Fig. 16). Allow
ample time for complete
drainage.
3. Wipe up any oil residue on
the unit and clean up any oil
that may have spilled.
Dispose of the oil according
to Federal, State and local
regulations.
4. Refill the crankcase with
3.04 fl.oz. (90 ml) of SAE 30
SF, SG, SH oil.
NOTE: Use the bottle and
spout saved from initial
use to measure the
correct amount of oil.
The top of the label on
the bottle measures
approximately 3.04
fi.oz. (90 ml) (Fig. 18).
Check the level, See
Checking the Oil Level.
If the level is low, add a
small amount of oil and recheck. Do not overfill (Fig. 14).

First, Check Fuel
Old fuel is usually the reason for improper unit performance. Drain and refill
the tank with fresh fuel prior to making any adjustments. Refer to Oil and
Fuel Information.
Second, Clean Air Filter
The condition of the air filter is important to the operation of the unit. A dirty
air filter will restrict air flow. This is often mistaken for an out of adjustment
carburetor. Check the condition of the air filter before adjusting the idle

Measure both the intake and exhaust valves.
The recommended clearance for both intake and exhaust is .003 - .006 in.
(.076 - 0.152 rnrn). Use a standard automotive .005 in. (0.127 mm) feeler
gauge. The feeler gauge should slide between the rocker arm and valve stem
with a slight amount of resistance, without binding. See Figures 26 and 27.
