OIL AND FUEL
USING THE RIGHT OIL
Use a high-quality SAE 30 weight oil. DO NOT use dirty oil. Failure
to use clean oil of the correct type can cause premature engine
wear and failure.
ADDING OIL: INITIAL USE
NOTE: This unit was shipped without oil in the crankcase. Oil must
be added before starting the unit.
NOTE: This unit comes with a 2.03 fluid oz. (60 ml) bottle of oil.
1. Unscrew the top of the oil bottle. Remove the paper seal.
Reinstall the top of the oil bottle.
2. Remove the cap from the oil bottle. Cut the tip off the funnel
spout (Fig. 6).
3. Set the unit on a flat, level surface.
4. Unscrew the oil fill plug (Fig. 7).
5. Pour the entire bottle into the oil fill hole (Fig. 7). DO NOT
overfill. Refer to Checking the Oil Level.
NOTE: Never add oil to the fuel tank. This unit has a four-cycle
engine. DO NOT mix oil with gasoline.
6. Wipe up any oil that may have spilled.
7. Reinstall the oil fill plug.
NOTE: Make sure the O-ring is in place on the oil fill plug (Fig. 7).
NOTE: Save the empty oil bottle. Use the bottle to measure the
correct amount of oil during future oil changes.

FUELING THE UNIT
1. Position the unit with the fuel cap facing up.
2. Remove the fuel cap.
3. Place the fuel container spout into the fill hole on the fuel tank
and fill the tank.
NOTE: Do not overfill the tank.
4. Wipe up any fuel that may have spilled.
5. Reinstall the fuel cap.
6. Move the unit at least 30 ft. (9.1 m) from the fuel container and
the fueling site before starting the engine.
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:
Remove the fuel cap slowly to avoid injury
from fuel spray. Never operate the unit without the fuel cap
securely in place.
WARNING:
Add fuel in a clean, well ventilated outdoor
area. Wipe up any spilled fuel immediately. Avoid creating
a source of ignition for spilled fuel. Do not start the engine
until fuel vapors dissipate.
USING THE RIGHT FUEL
The use of old fuel is the most common cause of performance
problems. Use only fresh, clean unleaded gasoline.
NOTE: This unit has a four-cycle engine. 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 make fuel and oil
separate, forming acids when stored. ALWAYS use fresh fuel (less
than 30 days old).
NOTE: Dispose of old fuel according to federal, state and local
regulations.
Using Blended Fuels
If using a blended fuel:
• Always use fresh unleaded gasoline
• Use the fuel additive STA-BIL
®
or an equivalent
• Drain the tank and run the engine dry before storing the unit
Using Fuel Additives
Use a fuel additive, such as STA-BIL Fuel Stabilizer or an
equivalent, to inhibit corrosion and minimize gum deposits. Add 0.8
oz. (23 ml) of fuel additive per gallon of fuel, according to the
instructions on the container. NEVER add fuel additives directly to
the unit's fuel tank.
WARNING:
DO NOT USE E85 FUEL IN THIS UNIT.
It has been proven that fuel containing greater than 10%
ethanol will likely damage this engine and void the warranty.

This unit is equipped with a bump head. Trimming line can be
released from the cutting head without stopping the engine.
To release more line, lightly tap the bump knob on the ground (Fig. 13)
while operating the unit at high speed. For best results, tap the bump
knob on bare ground or hard soil. Attempting to release line in tall
grass may stall the engine.
NOTE: Do not rest the cutting head on the ground while the unit is
running.
Each time the bump knob is tapped, about 1.5 inches (38 mm) of
trimming line is released.
NOTE: Always keep the trimming line fully extended. Line release
becomes more difficult when the cutting line gets shorter.
A blade in the cutting head shield will cut the line to the proper
length if any excess line is released.
HOLDING THE UNIT
• Stand in the operating position (Fig. 12). Stand up straight. Do
not bend over.
• Keep feet apart and firmly planted.
• Hold the shaft grip with the right hand. Keep the right arm
slightly bent.
• Hold the handle with the left hand. Keep the left arm straight.
• Hold the unit at waist level.
• Position the cutting head a few inches above the ground.
WARNING:
Always wear eye, hearing, hand, foot and
body protection to reduce the risk of injury when operating
this unit.
CAUTION: Do not remove or alter the line cutting blade
assembly. Excessive line length will make the unit
overheat. This may lead to serious personal injury or
damage to the unit.
TIPS FOR BEST RESULTS
• To direct clippings away from the operator, tilt the cutting head
slightly down to the right; cut from left to right whenever possible.
• Do not trim wet grass or weeds.
NOTE: Some line breakage will occur from:
• Entanglement with foreign matter
• Normal line fatigue
• Attempting to cut thick vegetation
• Forcing the line into objects such as walls or fence posts
