Install the Cutting Blade

1. Place the cutting blade on the output shaft

bushing (Fig. 13).

2. Make sure that the cutting blade is centered on

the pilot step and sitting flat against the output
shaft bushing (Fig. 14).

3. Align the shaft bushing hole with the locking

rod slot and insert the locking rod into the
bushing hole (Fig. 10).

4. Put the blade retainer and nut on the output

shaft. Make sure that the blade is installed
correctly.

5. Tighten nut counterclockwise against the blade

while holding the locking rod:

• If using a torque wrench and a 13 mm socket

tighten to:

325 - 335 in•lb, 27 - 28 ft.•lb, 37 -

38 N•m.

• Without a torque wrench, use a 13 mm closed-

end or socket wrench, turning the nut until the
blade retainer is snug against the shaft
bushing. Make sure that the blade is installed
correctly, then rotate the nut an additional 1/4
to 1/2 turn counterclockwise (Fig. 15).

6. Remove the locking rod from the locking rod

slot.

STARTING INSTRUCTIONS

ON ( I ) position at all times (Fig. 18).

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. 19). 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. 19).

5. Crouch in the starting position (Fig. 20). Squeeze the throttle control

lever. Pull the starter rope 5 times.

6. Place the choke lever in

Position 2

(Fig. 19)

7. Squeeze the throttle control, pull the starter rope in a controlled motion

3 to 5 times to start engine.

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

60 seconds.

9. Continue squeezing the throttle control, move the choke lever to

Position

(Fig. 19) and continue warming the engine for an additional 60 seconds.

The unit may be used during this time.

NOTE:

Unit is properly warmed up when engine accelerates without hesitation.

IF...

the engine hesitates, return the choke lever to

Position 2

(Fig. 19) and continue warm-up.

IF...

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

IF...

the engine fails to start after 2 attempts, place the choke lever in

Position 3

and squeeze the throttle

control. Pull

the starter rope out with a controlled and steady motion 3 to 8 times. The engine should start. If not,

repeat.

IF WARM...

If the engine is already warm, go back to step 6.

STOPPING INSTRUCTIONS

1. Release the throttle control and 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. 18).

•

Always agitate the fuel mix before fueling the unit

• Drain the tank and run the engine dry before storing the unit

USING FUEL ADDITIVES

The bottle of 2-cycle oil contains a fuel additive which will help inhibit
corrosion and minimize the formation of gum deposits. It is
recommended to use our 2-cycle oil with this unit.
If unavailable, use a good 2-cycle oil designed for air-cooled engines
along with a fuel additive, such as STA-BIL Gas Stabilizer or an
equivalent. 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.
Thoroughly mix the proper ratio of 2-cycle engine oil with unleaded fuel in a separate fuel can. Use a
40:1 fuel/oil ratio. Do not mix them directly in the engine fuel tank. See the table for specific gas and oil
mixing ratios.

NOTE:

One gallon (3.8 liters) of unleaded fuel mixed with one 3.2 oz. (95 ml) bottle of 2-cycle oil makes a 40:1

fuel/oil ratio.

NOTE:

Dispose of the old fuel/oil mix in accordance to federal, state and local regulations.

FUELING THE UNIT

1. Turn unit on its side, with the fuel cap facing up, and remove the fuel cap.
2. Place the gas container’s spout into the fill hole on the fuel tank 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.

CAUTION:

For proper engine operation and maximum

reliability, pay strict attention to the oil and fuel mixing instructions
on the 2-cycle oil container. Using improperly mixed fuel can
severely damage 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 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, level and 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.

STARTING AND STOPPING INSTRUCTIONS

WARNING:

Avoid accidental starting. Make sure you are in the

starting position when pulling the starter rope (Fig. 9). To avoid serious
injury, the operator and unit must be in a stable position while starting.

IF USING THE OPTIONAL ELECTRIC STARTER OR POWER START BIT™ ACCESSORY

OIL AND FUEL MIXING INSTRUCTIONS

Old and/or improperly mixed fuel are the main reasons for the unit not running properly. Be sure to use
fresh, clean unleaded fuel. Follow the instructions carefully for the proper fuel/oil mixture.

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. It
forms acids when stored. When using alcohol-blended fuel, use fresh fuel (less than 30 days old).

USING BLENDED FUELS

If choosing to use a blended fuel, or its use is unavoidable, follow recommended precautions:
• Always use the fresh fuel mix explained in the operator's manual

• Use the fuel additive STA-BIL® or an equivalent

OIL AND FUEL INFORMATION

WARNING:

It has been proven that fuel containing greater than 10% ethanol will likely damage this engine

and void the warranty.

REMOVE THE CUTTING BLADE AND INSTALL THE CUTTING ATTACHMENT

Remove the Cutting Blade

1. Align the shaft bushing hole with the locking rod slot and insert the locking rod into the bushing

hole (Fig. 10).

2. Hold the locking rod in place by grasping it next to the boom of the unit (Fig. 11).
3. While holding the locking rod, loosen the nut on the blade by turning it clockwise with a 13 mm

closed- end or socket wrench (Fig. 16).

4. Remove the nut, blade

retainer and blade. Store the
nut and blade together for
future use in a secure place.
Store out of children’s reach.

Install the Cutting Attachment

1. Align the shaft bushing hole

with the locking rod slot and
insert the locking rod into the
shaft bushing hole (Fig. 10).
Place the blade retainer on
the output shaft with the flat
surface against the output
shaft bushing (Fig. 17). Screw
the cutting attachment counterclockwise
onto the output shaft. Tighten securely.

NOTE:

The blade retainer must be installed on

the output shaft in the position shown for the
cutting attachment to work correctly.

2. Remove the locking rod.
3. Install the cutting attachment shield. Refer to

Remove and Install the Cutting Attachment
Shield.

WARNING:

Do not sharpen the cutting blade. Sharpening the blade can cause the blade tip to break off
