OIL AND FUEL INFORMATION

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. 14). To avoid serious
injury, the operator and unit must be in a stable position while starting.

OPERATING INSTRUCTIONS

HOLDING THE TRIMMER

Before operating the unit, stand in the operating position (Fig. 15). 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

TIPS FOR BEST TRIMMING RESULTS

• Keep the cutting head parallel to the ground.

• Do not force the cutting head. Allow the tip of the line to do the cutting, especially along walls. Cutting with more

than the tip will reduce cutting efficiency and may overload the engine.

• Cut grass over 8 inches (200 mm) by working from top to bottom in small increments to avoid premature line wear

or engine drag.

• Cut from right to left whenever possible. Cutting to the left improves the unit's cutting efficiency. Clippings are thrown

away from the operator.

• Slowly move the trimmer into and out of the cutting area at the desired height. Move either in a forward-backward or

side-to-side motion. Cutting shorter lengths produces the best results.

• Trim only when grass and weeds are dry.

• The life of your cutting line is dependent upon:

• Following the trimming techniques

• What vegetation is being cut

• Where vegetation is cut

For example, the line will wear faster when trimming against a foundation wall as
opposed to trimming around a tree. 

DECORATIVE TRIMMING

Decorative trimming is accomplished by removing all vegetation around trees, posts, fences and more.

Rotate the whole unit so that the cutting head is at a 30° angle to the ground (Fig. 16).

WARNING:

Always wear eye, hearing, foot and body protection to reduce the risk of injury when operating

this unit.

Fig. 15

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. 8).

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. 8).

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. 10). 

4. Pour the entire bottle of oil into the oil fill hole (Fig. 9).

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

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. 11).

2. Place the gas container’s spout into the fill hole on the fuel tank (Fig. 11) 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.

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, 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.

FIXED LINE INSTALLATION

Always use original equipment manufacturer 0.105
inch (2.67 mm) replacement line. Lines other than
those specified may make the engine overheat or fail.

To install the trimming line:

1. Insert each end of the replacement line into the

holes on either side of retention hook (Fig. 17).

2. Push the ends through until they stick out of

the sides of the head (Fig. 18).

3. Pull the ends through making sure that the

ends are of equal length and the middle of the
line is centered between the insertion holes
(Fig. 19).  

4. If the ends are not of equal length, push the

longer end back through the head part way and
pull the shorter end to compensate.  Repeat
until both ends are the same length.

5. Push the trimmer line until it lies flat against the

cutting head (Fig. 20).  Make sure the two
lengths of cutting line are of equal length.  If
they are not, adjust until they are.

CHECKING THE OIL LEVEL

The importance of checking and maintaining the
proper oil level in the crankcase cannot be
overemphasized. Check oil before each use:

1. Stop the engine and allow oil to drain into the

crankcase.

2. Place the unit on a flat, level surface to get a

proper oil level reading (Fig. 24).

3. Keep dirt, grass clippings and other debris out

of the engine. Clean the area around the
dipstick before removing it.

4. Remove the oil fill plug/dipstick and wipe off oil. Reinsert it all the way back in. (Fig. 22)

5. Remove the oil fill plug/ dipstick and check the oil level. Oil should be up to the top of the dipstick (Fig. 21).

6. If the level is low, add a small amount of oil to the oil fill hole and recheck (Fig. 22). Repeat this procedure until the

oil level reaches the top of the dipstick.

NOTE:

Do not overfill the unit.

NOTE:

Make sure the O-ring is in place on the oil fill plug/ dipstick when checking and changing the oil (Fig. 21).

CHANGING THE OIL

Change the oil while the engine is still warm. The
oil will flow freely and carry away more impurities.

1. Unplug spark plug boot to prevent accidental

starting.

2. Remove the oil fill plug/dipstick.

3. Pour the oil out of the oil fill hole and into a

container by tipping the unit to a vertical
position (Fig. 23). Allow ample time for
complete drainage.

4. Wipe up any oil residue on the unit and clean

up any oil that may have spilled. Dispose of the oil according to federal, state and
local regulations.

5. Refill the crankcase with 3.04 fl.oz. (90 ml) of SAE 30 SF, SG, SH oil. 

NOTE:

Use the bottle and spout saved from initial use to measure the correct
amount of oil. The top of the label on the bottle measures approximately
3.04 ounces (90 ml) (Fig. 25). Check the level with the dipstick. If the level
is low, add a small amount of oil and recheck. Do not overfill (Fig. 22).

6. Replace the oil fill plug/dipstick.

7. Reconnect the spark plug boot. 

WARNING:

To prevent extensive engine wear and damage to the unit, always maintain the proper oil

level in the crankcase. Never operate the unit with a low oil level.

CAUTION:
