ENGLISH
Using a phillips screwdriver, insert the guard screw and
u
tighten securely as shown in Figure E to complete the
guard assembly.
Once the guard is installed, remove the covering from the
u
line cut-off blade, located on the edge of the guard
Warning! Never use the tool unless the guard is properly
fitted.
Attaching the auxiliary handle (Fig. F, G, H)
To attach the handle, press in on the buttons (21) on both
u
sides of the upper housing as shown in Figure F.
Position the handle as shown in Figure G (with the
u
BLACK+DECKER logo facing upward). Partially push the
handle on so it will hold the buttons in when you release
them with your hand.
Push the handle completely onto the housing and position
u
it slightly until it "snaps" into place.
To adjust the handle up or down, press in on the button
u
(22) and raise or lower the handle (Figure H).
The handle should be adjusted so that your front arm is
u
straight when the trimmer is in the working position.
Height adjustment (Fig. I, J–J3)
Warning! Adjust the length of the trimmer to obtain proper
working positions shown in Figures J - J3.
The overall height of the trimmer can be adjusted by
u
loosening the height-adjust collar (6) by rotating it in the
direction of the arrow shown in Figure I.
Move the upper housing straight up or down. When the
u
desired height is achieved, tighten the collar by rotating it
opposite of the direction shown in Figure I.
Releasing the cutting line
In transit, the cutting line is taped to the spool housing.
Remove the tape holding the cutting line to the spool
u
housing.
Operation
Warning! Always use proper eye protection.
Warning! Before you begin trimming, only use the appropriate
type of cutting line.
Note: Inspect area to be trimmed and remove any wire, cord,
or string-like objects which could become entangled in the
rotating line or spool. Be particularly careful to avoid any wire
which might be bent outwardly into the path of the appliance,
such as barbs at the base of a chain link fence.
Switching on and off
To switch the appliance on, push the lock-off button (2),
u
and squeeze the trigger (1).
To switch the appliance off, release the trigger.
u

u
side to side as shown in Figure J.
12
(Original instructions)
Maintain a cutting angle of 5° to 10° as shown in
u
Figure J1. Do not exceed 10° (Figure J2). Cut with the tip
of the line. To keep distance from hard surfaces use edge
wheel (9).
Maintain a minimum distance of 60 cm between the guard
u
and your feet as shown in Figure J3. To acheive this
distance adjust the overall height of the trimmer as shown
in Figure I.
POWERCOMMAND Button (Fig. K)
The POWERCOMMAND feature allows you to advance the
length of cutting line available while trimming.
To extend the cutting line, fully depress the
u
POWERCOMMAND button (4) while trimming and then
release (figure K).
Note: The trimmer will stop cutting when the
POWERCOMMAND button is pressed and will resume cutting
when released.
For maximum line length, press the button multiple times
u
until you hear the cutting line hitting the guard.
Note: Do not continue to press the POWERCOMMAND
button once the maximum length is reached. This will result in
overfeeding and will consume string quickly.
Convert to edging mode (Fig. L, M)
Warning! The wheeled edge guide should only be used when
in the edging mode.
The trimmer can be used in trimming mode or edging mode to
trim overhanging grass along lawn edges and flower beds. For
edging, the trimmer head should be in the position shown in
Figure M. If it is not:
Remove the battery from the trimmer.
u
Grasp the flip-to-edge collar (7) and push down as
u
shown in part 1 of Figure L.
Rotate the flip-to-edge collar 180° counterclockwise as
u
shown in part 2, until the handle snaps back into the
upper half of the trimmer.
To return to trimming position, pull the flip-to-edge collar
u
down and rotate the head clockwise back to its original
position.
Note: You will experience faster than normal cutting line wear
if the trimmer line is positioned directly over the sidewalk or
abrasive surface.
Edging (Fig. M)
Warning! When being used as an Edger, stones, pieces of
metal and other objects can be thrown out at high speed by
the line. The trimmer and guard are designed to reduce the
danger. However, MAKE SURE that other persons and pets
are at least 30 m away. Optimum cutting results are achieved
on edges deeper than 50 mm.
Do not use this trimmer to create trenches.
u
Using the edging wheel (9), guide the trimmer as shown in
u
Figure M.
