Oil And Fuel Information - Craftsman 316.77237 Operator's Manual

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.
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. 7).
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. 7).
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. 8).

gas or gas 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 gasoline 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 the 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
WARNING:
Add gasoline in a clean, well ventilated
outdoor area. Wipe up any spilled fuel immediately. Avoid
creating a source of ignition for spilt gasoline. Do not start
the engine until gasoline 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.
1. Remove the gas cap.
WARNING:
Remove gas cap slowly to avoid injury
from fuel spray. Never operate the unit without the gas
cap securely in place.
2. Place the gas container's spout into the fill hole on the fuel tank
(Fig. 10) and fill the tank.
Gas Can Spout
NOTE: Fill or add gas to the tank only when the edger is in the
horizontal position.
NOTE: Do not overfill the tank.
3. Wipe up any gasoline that may have spilled.
4. Reinstall the gas cap.
5. Move the unit at least 30 ft. (9.1 m) from the fueling source and
site before starting the engine.
