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.
INSTALL AND ADJUST THE J-HANDLE
1. Place the J-handle between the top and middle clamp pieces (Fig. 2).
2. While holding the 3 pieces together, install the 4 screws through the top clamp
and into middle clamp.
NOTE: The holes in the top and middle clamp will line up only when assembled correctly.
3. Place the clamps and the J-handle over the shaft housing and onto the bottom clamp.
4. Hold each hex nut in the bottom clamp recess with a finger. Start screws with a
large Phillips screwdriver. Do not tighten until making the handle adjustment.
5. Slide the J-handle in or out until the arrow/white line on the decal touches the clamp
assembly (Fig. 2). You must first loosen the screws if the handle is pre-installed.
6. While holding the unit in the operating position (Fig. 13), position the J-handle to
the location that provides you the best grip.
7. Tighten the clamp screws evenly until tight.

WARNING:
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.
Oil Fill Plug
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.
Fuel Cap
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).
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.

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
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:
Avoid creating a source of ignition for spilt fuel. Do not start the engine until fuel vapors dissipate.
WARNING:
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.
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 container.
NEVER add fuel additives directly to the unit's gas tank.
FUELING THE UNIT
WARNING:
Never operate the unit without the fuel cap securely in place.
WARNING:
proven that fuel containing greater than 10% ethanol will likely
damage this engine and void the warranty.
