Sears 316.79197 Trimmer User Manual


 
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.
Use a high-quality SAE 30 weight oil of API (American Petroleum
Institute) service class SF, SG, SH.
ADDING OIL TO CRANKCASE: INITIAL USE
NOTE: This unit is shipped without oil. In order to avoid damage to
the unit, put oil in the crankcase before you attempt to start
the unit.
Your unit is supplied with one 3.04
fluid oz. (90 ml.) bottle of SAE 30 SF,
SG, SH oil (Fig. 3).
NOTE: Save the empty oil bottle. It
can be used to measure the
correct amount during future
oil changes. See Changing the
Oil.
1. Unscrew the top of the bottle of
oil and remove the paper seal
covering the opening. Replace
the top. Next, cut the tip off the
funnel spout (Fig. 3).
2. Tip unit so that the back of the
engine is facing up in a vertical
position.
3. Remove the oil fill plug from the
crankcase (Fig. 4).
4. Pour the entire bottle of oil into
the oil fill hole (Fig. 5).
NOTE: Never add oil to the fuel or
fuel tank.
5. Wipe up any oil that may have
spilled and reinstall the oil fill
plug.
Check oil before each use and
change as needed. Refer to
Checking the Oil Level.
RECOMMENDED FUEL TYPE
Old fuel is the primary reason for improper unit performance. Be
sure to use fresh, clean, unleaded gasoline. Dispose of the old
gasoline in accordance to Federal, State and Local regulations.
NOTE: This is a four cycle engine. In order to avoid damage to the
unit, do not mix oil with gasoline.
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 form acids when stored.
Use fresh fuel (less than 60 days old), when using alcohol-blended fuel.
Using Blended Fuels
If you choose to use a blended fuel, or its use is unavoidable, follow
recommended precautions:
Always use fresh unleaded gasoline
Use a gas stabilizer fuel additive
Drain tank and run the engine dry before storing unit
Using Fuel Additives
The use of a gas stabilizer 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.
FUELING THE UNIT
1. Remove the fuel cap (Fig. 6).
2. Place the gas container’s spout into the fill hole on the fuel tank
(Fig. 5) and fill the tank.
NOTE: Do not overfill the tank.
3. Wipe up any gasoline that may have spilled.
4. Reinstall the fuel cap.
5. Move the unit at least 30 ft. (9.1 m) from the fueling source and
site before starting the engine.

WARNING: Add fuel in a clean, well ventilated
outdoor area. Wipe up any spilled fuel immediately.
Avoid creating a source of ignition for spilt fuel. Do not
start the engine until fuel vapors dissipate.
WARNING: Gasoline is extremely flammable. Ignited
vapors may explode. Always stop the engine and allow
it to cool before filling the fuel tank. Do not smoke while
filling the tank. Keep sparks and open flames at a
distance from the area.
WARNING: OVERFILLING OIL CRANKCASE MAY
CAUSE SERIOUS PERSONAL INJURY. Check and
maintain the proper oil level in the crank case; it is
important and cannot be overemphasized. Check the
oil before each use and change it as needed. See
Changing the Oil.
