warnings and instructions may result in electric
shock, fire and/or serious injury.
Save all warnings and instructions for future
reference.
General Electric Gardening Tool Safety
Warnings –Work Area Safety
Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases or dust. Power tools
create sparks which may ignite the liquids,
fumes or dust.
Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.
General Electric Gardening Tool Safety
Warnings –Electrical Safety
Battery charger plugs must match the outlet.
Never modify the plug in any way. Do not
use any adapter plugs with earthed
(grounded) chargers. Unmodified plugs and
matching outlets will reduce risk of electric
shock.
Avoid body contact with earthed or
grounded surfaces such as water pipes.
There is an increased risk of electrical shock if
your body is earthed or grounded.
Do not expose power tools, battery chargers
or batteries to rain or wet conditions. Water
entering the tool, chargers or batteries will
increase the risk of electric shock.
Do not abuse the cord. Never use the power
cord for carrying, pulling or unplugging the
charger. Keep the power cord away from
heat, oil, sharp edges, and moving parts.
Damaged or entangled cords increase the risk
of electric shock.

operator or bystander.
Utilize extra caution, when the trimmer is being
used as an Edger or Sweeper, especially near,
or 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 off 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.

ADJUSTING THE TELESCOPING SHAFT
The telescoping shaft length can be adjusted to
suit the height of the person operating the tool.
1. Rotate the telescoping shaft locking collar
(1) counter clockwise one turn (Fig. 7).
2. Slide the lower section of the telescoping
shaft (2) in or out until the desired shaft
length is achieved.
NOTE: The shaft length can be adjusted
approximately 12” (30.5 cm).
3. Turn the locking collar clockwise to lock the
telescoping shaft at the desired length.
NOTE: Hand tighten the locking collar.
INSTALLING THE EDGING WHEELS
The edging wheels are used as an aid to control
the string trimmer while edging. Once installed,
they may be left in position for all trimming
activities or they may be removed and stored in
a safe location.
1. Slide the edging wheel bracket (1) over
the mounting bracket (2) on the trimmer
(Fig. 8).
NOTE: Make sure the grooves (3) in the
edging wheel bracket and the tabs (4) on
the mounting bracket are aligned.
2. Press the edging wheel bracket onto the
mounting bracket as far as it will go.

ADJUSTING TRIMMER HEAD ANGLE
The trimmer head angle can be adjusted to four
different angles. These adjustments will
accommodate various positions that may be
desired by the operator.
1. Press the head angle button (1) (Fig. 9).
2. While pressing the head angle button,
rotate the handle (2) to the desired angle.
3. Release the head angle button and rotate
the handle up and down slightly until the
button “clicks” to lock the head in position.
SETTING THE TRIMMING GUIDE
The trimming guide is used to protect the
trimmer line when trimming close to objects
such as fence posts, fences, decks etc.
To position the trimming guide (1), simply pull it
down to its horizontal position (2) (Fig. 10).
When the trimming guide is not being used, it
should be placed in its upright position.
ROTATING THE TRIMMER HEAD FOR
EDGING
The trimmer head must be rotated to the vertical
position for edging. Rotate the trimmer head as
follows:
1. Grasp the telescoping shaft locking collar
(1) with one hand (Fig. 11).
2. Grasp the trimmer head rotation lock (2)
and pull it toward the handle (Fig. 11).
3. While pulling on the trimmer head rotation
lock, turn the lock 90° then release the
lock. Make sure the rotation lock “clicks”
into place to lock the handle in position.
NOTE: The handle can be rotated 90°
either left or right, depending upon the
operator’s preference.
ADJUSTING THE LINE LIMITING KNIFE
It is important to limit the length of trimming line
that is exposed outside the trimmer spool. The
line limiting knife will automatically cut the
exposed line to the correct length. The string
trimmer is shipped from the factory with the line
limiting knife positioned to cut the line at the
correct length that will produce a 10” (25.4 cm)
cutting diameter. This is the optimum line length
to produce both efficient cutting action and to
provide the longest battery life.
If a longer line length is desired for trimming a
larger swath or closer to objects, the line limiting
knife can be repositioned as follows:

screwdriver.
3. Turn the line limiting knife (3) 180° (4) and
reinstall the screw.
NOTE: Make sure the line limiting knife is
properly nested in the cavity before
tightening the screw.
LOCK-OFF AND TRIGGER SWITCHES
The string trimmer is equipped with both a lock-
off and trigger switch. To turn the string trimmer
ON:
1. Press the lock-off switch (1) (Fig.13).
2. While continuing to press the lock-off
switch, squeeze the trigger switch (2).
3. When the string trimmer starts, release the
lock-off switch while continuing to squeeze
the trigger switch. The string trimmer will
continue to run.
4. To turn the string trimmer OFF, release the
trigger switch.
NOTE: To restart the string trimmer, press
the lock-off switch and squeeze the trigger
switch.
REPLACING THE TRIMMER LINE SPOOL
WARNING: Remove the battery from the
tool before attempting to replace the trimmer
line spool.
As the trimmer is used, the line will automatically
be dispensed from the spool. In time, the line
supply within the spool will be depleted, making
it necessary to replace the spool with a new pre-
wound spool.
NOTE: You can purchase a replacement pre-
wound spool #189465 at your local True Value®
store.
Removing the old spool
1. Press the spool locking buttons (1) into the
spool housing (2) (Fig. 14).
NOTE: There are two spool locking buttons
located on opposite sides of the spool
housing.
2. While pressing on both spool locking
buttons, pull the spool cap (3) out of the
spool housing (Fig. 15).
3. Pull the empty spool (4) upward to remove
the spool and any remaining trimmer line
from the spool housing (Fig. 16).

4. Once the empty spool has been removed
from the spool housing, use a soft brush to
remove any debris from the spool housing.
Installing the replacement 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 fingers to prevent it from unwinding
from the spool.
2. Pull the loose end of the trimmer line out of
the retaining slot (5) in the spool (Fig. 17).
NOTE: Be sure to hold the line in place
with your fingers to prevent it from
unwinding from the spool.
3. Unwind approximately 5” (12.7 cm) of line
from the spool before threading the loose
line through the hole in the spool housing.
4. Thread the loose end of the trimmer line (6)
through the hole (7) in the spool housing
(2).
5. While holding pulling slightly on the loose
line, slide the spool onto the housing
spindle (8) as far as it will go.
6. Once the replacement spool is fully
inserted into the spool housing, replace the
spool cap (3) by inserting the locking
buttons (1) into the spool housing.
7. Press the spool cap fully into the spool
housing until the locking buttons “click” into
the matching holes (9) in the spool
housing.
NOTE: If the spool cap locking buttons do
not “click” into place, check to make sure
there is no debris in the spool housing that
is preventing the spool cover from properly
locking into place. The spool will become
dislodged from the spool housing if not
properly locked in place.
8. When the new trimmer line spool is
installed, approximately 3” (7.6 cm) of
trimmer line should be exposed beyond the
spool housing. If it is too long, cut it to
length with scissors. If it is too short, press
the line release button (10) on the trimmer
line housing and gently pull on the exposed
trimmer line (Fig. 18).
NOTE: Each time you press the line
release button it will release approximately
½” (13 mm) of line from the spool.

AUTOMATIC INERTIA LINE FEED SYSTEM
If the trimmer line becomes too short while
trimming, simply release the trigger and let the
spool come to a complete stop. The inertia line
feed system will automatically feed additional
trimmer line out from the spool when the trimmer
is restarted.
GENERAL TRIMMING GUIDELINES
WARNING: Be extremely careful when
cutting around hard objects such as rock,
gravel, fence posts etc. that can be contacted by
the line or the spool housing. Contacting these
items with the line or spool housing may cause
pieces of the trimmer line and debris to be
violently thrown. It may also cause the line to
become entangled and damage both the line
and the spool housing.
When trimming, do not feed the line into the
work area too quickly and crowd the line. Only
the tip of the line does the cutting. Feeding the
line into the work area too quickly will reduce the
head speed, slow the cutting action and
overload the motor. It will also reduce the
battery pack capacity before requiring
recharging.
NOTE: The trimming line will easily remove
grass and weeds from around walls, fences,
trees and flower beds, but it can also cut the
tender bark of trees or shrubs, scar fences, etc.
Be extremely careful when trimming near
objects that can be easily damaged by the
trimmer line.
Trim grass only when it is dry. Trim during the
middle of the day when the grass is completely
dry. Trimming wet grass will prevent the trimmer
from cutting cleanly. Trimming wet grass will
also shorten the battery life.
Always use two hands while operating the
trimmer. Use one hand on the main handle to
operate the switches and the other on the assist
handle.
Use a semi-circular sweeping motion, with the
trimmer head tilted slightly downward where the
trimmer line is cutting the grass.
Move the trimmer from right to left, feeding it
into the uncut grass on the left side. This motion
will cause the trimmer to throw the cut grass
away from the operator, reducing the amount
that is thrown toward the operator.
ASSEMBLY AND OPERATING
For safety reasons, the operator must
read the sections of this Owner’s Manual
entitled GENERAL SAFETY WARNINGS,
ELECTRIC GARDENING TOOL SAFETY,
SPECIFIC SAFETY RULES, BATTERY &
CHARGER SAFETY, BATTERY PACK
RECYCLING and SYMBOLS before using
this grass trimmer.
Verify the following every time the grass
trimmer is used:
1. Safety glasses or goggles, hearing
protection device, hearing protection
and all required safety clothing are
being worn.
2. Appropriate length of trimming line is
exposed beyond the trimmer line
housing.
3. The area to be trimmed is cleared of
all dangerous debris.
4. Bystanders are at least 50' (15 m)
away from the trimming area.
Failure to observe these safety rules will
significantly increase the risk of injury.
