WARNING!

Do not smoke or allow smoking near fuel or the Trimmer.
Mix and pour fuel outdoors WHERE THERE ARE NO
SPARKS OR FLAMES.
The 2-cycle engine on your Trimmer requires that fuel and
2-cycle engine oil be pre-mixed before adding to the
trimmer’s fuel tank. To mix the fuel/ 2-cycle oil:

1. Throttle

(Fig. 15)

The throttle lever (12) is located on the top crossbar on

the upper handle. Depressing the throttle lever will
increase the engine speed. At idle speed the clutch is
disengaged and the trimmer head will not turn. As engine
speed is increased, the automatic clutch will engage and
rotate the trimmer head. Upon release, the throttle lever
is spring loaded to return to idle speed.

2. Swivel to offset trimmer head (Fig. 16)

Your wheeled string trimmer mower is designed with the

ability to offset the trimming head from a centered
position to a right side position. This is accomplished by
depressing the swivel control lever (13) on the right
upper handle. By depressing the swivel control lever, the
head becomes unlocked and can be swiveled to two
positions to the right. Upon release of the swivel control
lever, a pin will lock the trimmer head into the desired
position. Swiveling the trimmer head allows for easy
mowing / trimming around obstacles such as posts or trees
and under fences.

3. Bevel trimming adjustment

(Fig. 17)

The line will normally cut approximate 50mm high. When

it is desired that the line cut closer to the ground, a bevel
adjustment is available. Bevel handle (4) is located just in
front of the left wheel. This handle can be deflected
outward and rotated to two different positions. This will
position the trimmer head at an angle and allow the line
to cut closer to the ground. This is especially useful when
trimming next to raised sidewalks or building foundations.

4. Start / Stop switch (Fig. 18)

On/Off ignition switch (17) is located on the engine air

filter housing. The switch must be in the “On” position for
the engine to run. Moving the switch to the “Off” position
will stop the engine.

1. Your Trimmer performs best when the engine operates at

high speed and the tips of the line cut the vegetation. Do
not force the trimmer line into grass faster than the
Trimmer’s cutting speed permits.

2. The tips of the line can cause damage to trees, shrubs

and fences. To avoid damage in these conditions, you
may choose to run the engine at lower speeds and
should carefully monitor the location of the cutting line.

3. Because the cutting head can be pivoted to the right side,

plan to trim objects (fences, buildings, etc.) in a clockwise
manner.

4. When trimming next to wire type fencing, avoid

cutting-line contact with the fence. Contact will result in
rapid line wear. Likewise, contact with concrete and brick
surfaces will result in rapid line wear.

5. Do not allow the trimmer head metal bowl to ride on top

of concrete or asphalt surfaces. This will cause wear to
the metal bowl. The bowl was designed to ride on grass
surfaces.

6. It is recommended that the line be replaced when it is

worn to approximately ½ the original length. This will help
maintain a high tip speed and result in a clean cut. It is
strongly recommended that the engine cooling air screen
be wiped clean at every string change. This will prevent
engine overheating.

7. Choose your line diameter according to the following

criteria:
a. 2.4 / 2.7 mm diameter: Best overall choice for yard

use. This diameter results in a good quality of cut and
moderate wear rate.

b. 4.0 mm diameter: Ability to cut larger diameter stalks

and has the best wear rate.

Recommendations

1. Use fresh unleaded gasoline with an octane rating of 87

or higher. Do not use gasoline containing more than 10%
ethanol.

NOTICE:

Use of gasoline containing more than 10%

ethanol can damage Trimmer. Use of non-ethanol
gasoline is best.

2. Always use 2-cycle oil that meets or exceeds JASO – FC
