OIL AND FUEL INFORMATION

INSTALLING THE CUTTING SHIELD

Use the following instructions if the cutting
attachment shield on the unit is not installed or if
needing to re-install it.

1. Place the cutting attachment shield onto the shaft

housing above the clamp assembly (Fig. 1).

2. Push the cutting attachment shield down to the

top of the cutting attachment assembly. Then
rotate the shield until its screw holes line up
with the holes in the cutting attachment. The
shield guard should fit into the recessed pocket
(Fig. 1).

3. Install the screws with a Phillips screwdriver (Fig. 2).

INSTALL AND ADJUST THE D-HANDLE

1. Push the D-handle down onto the shaft housing so that the handle slants towards

the shaft grip (Fig. 3). The squared bolt hole in the handle is to the right.

2. Insert the shoulder bolt into the squared hole in the handle and push through. On

the left side of the handle, place the washer on the bolt, then screw the wing nut
onto the bolt. Do not tighten until you make the handle adjustment.

3. Rotate the D-handle to place the grip above the top of the shaft housing. Place it

a minimum of 6 inches (15.24 cm) from the end of the shaft grip.

4. While holding the unit in the operating position (Fig. 7), position the D-handle to the location that will provide the

best grip.

5. Tighten the wing nut until the D-handle is secure.

STARTING/STOPPING INSTRUCTIONS

WARNING:

Remove fuel cap slowly to avoid injury from fuel spray.

Never operate the unit without the fuel cap securely in place.

WARNING:

Avoid accidental starting. Make sure you are in the

starting position when pulling the starter rope (Fig. 12). To avoid serious
injury, the operator and unit must be in a stable position while starting.

STARTING INSTRUCTIONS

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 Control is in the ON ( I )
position at all times (Fig. 11).

3. Fully press and release the primer bulb 10 times, slowly. Some amount of fuel

should be visible in the primer bulb and fuel lines (Fig. 12). If fuel can not be seen
in the bulb, press and release the bulb until fuel is visible.

4. Place the choke lever in

Position 1

(Fig. 12).

5. Crouch in the starting position (Fig. 13). Squeeze the throttle control and pull the

starter rope 5 times.

6. Place the choke lever in

Position 2

(Fig. 12).

7. While squeezing the throttle control, pull the starter rope in a controlled motion 3

to 5 times to start the engine.

8. Keep the throttle squeezed and allow the engine to warm up for 30 to 60 seconds.

9. While continuing to squeeze the throttle control, move the choke lever to

Position 3

(Fig. 12).

10. Continue squeezing the throttle control and warm the engine for an additional 60

seconds. During this time the unit may be used.

IF...

The engine does not start, go back to step 3.

IF...

The engine fails to start after a few attempts, place the choke lever in

Position 3

and squeeze the throttle

control. Pull the starter rope briskly 3 to 8 times. The engine should start. If not, repeat.

STOPPING INSTRUCTIONS

1. Release your hand from the throttle control. Allow the engine to cool down by idling.

2. Press and hold the On/Off Control switch in the OFF (O) position until the unit comes to a complete stop (Fig. 11).

OPERATING INSTRUCTIONS

HOLDING THE TRIMMER

Before operating the unit, stand in the operating position (Fig. 14). Check for the following:

• The operator is wearing eye protection and proper clothing

• With a slightly-bent right arm, the operator’s hand is holding the shaft grip

• The operator’s left arm is straight, the left hand holding the J-handle

• The unit is at waist level

• The cutting head is parallel to the ground and easily contacts the grass without

the need to bend over

ADJUSTING TRIMMING LINE LENGTH

The Bump Head™ cutting head allows you to release trimming line without stopping
the engine. To release more line, lightly tap the cutting head on the ground (Fig. 15)
while operating the trimmer at high speed.

NOTE:

Always keep the trimming line fully extended. Line release becomes more
difficult when the cutting line gets shorter.

Each time the head is bumped, about 1 inch (25.4 mm) of trimming line releases. A blade in
the cutting head shield will cut the line to the proper length if any excess line is released.

For best results, tap the bump knob on bare ground or hard soil. If you attempt a line release in tall grass, the engine may
stall. Always keep the trimming line fully extended. Line release becomes more difficult when the cutting line gets shorter.

WARNING:

Always wear eye, hearing, 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.

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 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. 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. 9).

4. Pour the entire bottle of oil into the oil fill hole (Fig. 8).

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 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 the fuel additive STA-BIL® or an equivalent

• Drain tank and run the engine dry before storing unit

Using Fuel Additives

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

1. Remove the fuel cap (Fig. 10).

2. Place the gas container’s spout into the fill hole on the fuel tank (Fig. 10) 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 to Federal, State and Local regulations.
