or debris thrown by the rotating polymer line or trimmer.
Thrown objects may also ricochet and strike the operator or bystander. Utilize extra
caution, when the trimmer is being used on paved or hard surfaces, as pieces of
metal, concrete, brick, stones, gravel, sand, glass, sticks and other objects can be
thrown at high speed and force by the rotating line and such objects can be thrown,
skip along or ricochet long distances o of hard surfaces. Do not use this trimmer
for sweeping debris that may contain hard objects, e.g. pebbles, stones, sticks,
glass, metal, etc. as such hard objects can be thrown with great force and cause
injury to the operator or bystanders, and / or damage property, e.g., screens,
windows, building siding, glass doors, or vehicles.
NOTE: Avoid operating the trimmer near property that can be easily damaged
by thrown or ricocheting objects such as screens, windows, building siding, glass
doors and vehicles.
WARNING: To reduce the risk of ricochet / rebound injury or property
damage, work by going away from any nearby solid object such as wall, steps,
large stones, tree, etc. Use great care when working close to solid objects.
WARNING: Inspect the area to be trimmed for hazards before each use.
Remove any foreign objects such as sticks, rocks, broken glass, nails, wire,
tools, toys, etc. which can be thrown by or become entangled in the trimmer
line. Always locate, and then avoid cutting near electrical power lines, power
conduit, or extension power cords. Avoid contacting hard objects with the trimmer
head as the objects can damage the trimmer head and / or the objects can be
thrown causing serious injury.

ADJUSTING THE TRIMMING LINE
The trimmer head allows the operator to release more cutting line without stopping
the motor. As line becomes frayed or worn, additional line can be released by lightly
tapping the bump knob on the ground while operating the trimmer.
For best results, tap the bump knob on bare ground or hard soil as Figs. 8 & 9.
The motor may overheat if line release is attempted in tall grass.
LINE TRIMMING KNIFE
It is important to limit the length of trimming lime that is exposed outside the
trimmer spool. The line trimming knife will automatically cut the exposed line at
the correct length that will produce a 12" (30.5 cm) cutting diameter. This is the
optimum line length to produce both ecient cutting action and to provide the
longest battery life. The motor may overheat if line release is attempted in tall grass.
Adjusting the Assist handle (Fig.7b).
NOTE: The assist handle mounting bracket can be slid up or down the shaft,
rotated from side to side or tilted forward or backward to place the assist handle
in the most comfortable position. Turn locking lever(1) before adjusting the assist
handle position and retighten it to lock the assist handle in the new position.

INSTALLING THE REPLACEMENT SPOOL
Remove all packaging from the replacement spool.
1. Pull the loose ends of the
trimmer lines out of the
retaining slots in the spool.
NOTE: Be sure to feed the
lines into the notches on each
side of the outer face of the
spool to prevent them from
unwinding. Ensure you remove
both lines from the notches
before feeding the lines into the
eyelets on the spool housing.
2. Unwind approximately 5" (12.7 cm) of the line from the spool before
threading the loose end of trimmer lines through the respective eyelets
in the spool housing.
3. While holding pull slightly on the loose lines, slide the spool onto the housing
spindle as far as it will go.
4. Once the replacement spool is fully inserted into the spool housing, replace the
spool cap by inserting the locking buttons into the spool housing.
5. Press the spool cap fully into the spool housing until the locking buttons “click”
into the matching holes in the spool housing.
6. Bump line out as necessary.
MANUAL INSTALLING AND WINDING NEW LINE ON SPOOL
1. Remove all packaging from the replacement spool. NOTE: There may be shrink
wrap holding the trimmer line in place on the replacement spool. This must be
removed, but be sure to hold the line in place with your ngers to prevent it from
unwinding from the spool.
2. Press the two release tabs on the spool base and remove the spool retainer
by pulling it straight out (FIG 14).
3. Remove the spool. Use a clean cloth to clean the inner surfaces of the spool
retainer and spool base.
4. Check the spool retainer, spool, and spool base for worm parts.
5. Take approximately 15'(4.5 m) of 0.08"(2.0 mm) diameter cutting line. Fold the
line in half and then adjust it so that one end is 4 1/2"(11 cm) longer than the
other (FIG 15).
6. Hold the folded end of the cutting line onto either of the slots in the spool.
7. Wind the line, in two even and tight layers, onto the spool. Wind the line in the
direction indicated on the spool.
8. Place the ends of the line in the two opposite notches in the spool, with
approximately 5"(12.5 cm) protruding from each side (FIG 16).
