ASSEMBLY INSTRUCTIONS

INSTALL CUTTING ATTACHMENT SHIELD
WARNING: To prevent serious personal injury, never operate the trimmer without the
cutting attachment shield in place.
Use the following instructions if the cutting attachment shield on
your unit is not installed. Use only the instructions that apply to
the type of shaft and shield that your unit is equipped with.
1. Place the cutting head shield onto the guard mount bracket,
making sure to align the holes on the shield with the holes in
the guard mount bracket. (Fig. 1)
2. Take the 2 shield screws and screw each one into the shield
until finger tight.
3. Using an appropriate screw driver, tighten the screws until the
shield is firmly in place. Make sure the screws are tightened
equally so there is a balanced gap between the bracket and
the shield on each side.
ADJUSTING THE D-HANDLE
1. Loosen the bolt on the handle just enough to move it (Fig. 2).
2. While holding the unit in the operating position (Fig. 9), move the
D-handle to the location that provides the best grip.
3. Tighten the bolt until the D-handle is secure. (Fig. 2)

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
Oil Fill Plug
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. 6).
NOTE: Save the bottle of oil. 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.
6).
Primer
Bulb
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).
4. Pour the entire bottle of oil into the oil fill hole (Fig. 7).
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.
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 make fuel and oil separate or
form acids when stored. Use fresh fuel (less than 30 days old), when using alcohol-blended fuel.
Using Blended Fuels
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.
If you choose 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
USING FUEL ADDITIVES
WARNING:
Remove fuel cap slowly to avoid injury from fuel
spray. Never operate the unit without the fuel cap securely in place.
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.
The use of fuel additives, such as STA-BIL® Gas Stabilizer or an
Shield 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 container. NEVER add fuel additives
directly to the unit's gas tank.
FUELING THE UNIT
1. Remove the fuel cap (Fig. 9).
2. Place the gas container's spout into the fill hole on the fuel tank (Fig. 9) 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.
NOTE: Dispose of the old gasoline in accordance with federal, state and local regulations.
STARTING INSTRUCTIONS
WARNING:
Operate this unit only in a well-ventilated outdoor
area. Carbon monoxide exhaust fumes can be lethal in a
confined area.
WARNING:
Avoid accidental starting. Make sure you are in
the starting position when pulling the starter rope (Fig. 22). To
avoid serious injury, the operator and unit must be in a stable
position while starting. Make sure that any Add-On item is
installed correctly and secure before starting the unit.
1. Check the oil level in the crankcase. Refer to Checking the Oil Level.
2. Fill the fuel tank with fresh, clean unleaded gasoline. Refer to Fueling
the Unit.
NOTE: There is no need to turn the unit on. The On/Off Stop Control is in
the ON ( I ) position at all times (Fig. 10).
3. Fully press and release the primer bulb 10 times, slowly. Some
amount of fuel should be visible in the primer bulb (Fig. 11). If fuel

visible.
4. Move the choke lever to Position 1 (Fig. 11).
5. Crouch in the starting position (Fig. 12). SQUEEZE and HOLD the
throttle control for ALL further steps. Pull the starter rope 5 times.
6. Continue to squeeze the throttle control. Move the choke lever to
Position 2 (Fig. 11).
7. Continue to squeeze the throttle control. Pull the starter rope 3-5
times to start the engine.
8. Continue to squeeze the throttle control. Allow the engine to warm up for 30-60 seconds.
9. Continue to squeeze the throttle control. Move the choke lever to Position 3 (Fig. 11).
10. Continue to squeeze the throttle control. Run the unit for an additional 60 seconds to complete the
warm-up. The unit may be used during this step.
NOTE: The unit is properly warmed up when the engine accelerates without hesitation.
IF... the engine hesitates, return the choke lever to Position 2 and continue the warm-up.
IF... the engine does not start, go back to step 3.
IF... the engine fails to start after a few attempts, move the choke lever to Position 3 and squeeze the
throttle control. Pull the starter rope 3-8 times. The engine should start. If not, repeat.
IF THE ENGINE IS HOT... Move the choke lever to Position 2, press the primer bulb 10 times,
squeeze the throttle control and pull the starter rope until the unit starts. Run the unit for 2-5
minutes. The unit may be used during this time. Then move the choke lever to Position 3.
