guard must always be on the tool to protect the user.
► Remove the two guard sections from the carton.
► Attach the first guard section with side tab into the groove
around the housing as shown in
Fig. A.
Align the hole in
the guard with the post on the trimmer housing.
► Remove the screw from the second guard section.
► Insert the top tab from the second guard section into the
first guard section as shown in
Fig. B.
Note:
The rib behind the tab should be hooked over the
rib of the first guard section
Fig. B.
► Insert the side tab from the first guard section into the slot
of the second guard section until you hear them “snap”
together
Fig. C.
► Insert the 3/4 inch (19mm) screw as shown in
Fig. D
to
complete the guard assembly.
► Once the guard is installed, remove the covering from
the line cut-off blade, located on the edge of the second
guard section.
Attaching the Auxiliary Handle
► Attach the handle to the metal shaft of the trimmer (with
the Black & Decker logo facing upward) by pushing it onto
the shaft from the side. Once it is pushed onto the metal
shaft, the handle can be turned into the correct orientation.
► Insert the 2-1/2 inch (63.5mm) bolt through the holes in the
handle and thread on the plastic knob as shown in
Fig. 5.
► For maximum comfort and control, adjust the auxiliary
handle to suit your height. Shorter users adjust handle
to a lower position (away from you) and taller users,
adjust handle to an upper position (towards you). The
handle should be adjusted so that your front arm is straight
when the trimmer is in the working position.
Height Adjustment
► The overall height of the trimmer can be adjusted by
pressing the button shown in
Fig. F
and moving the
metal tube up or down into one of the three rectangular
recesses in the tube until you hear it “snap” into place.
Caution!
Confirm that the tube is locked in place by
releasing the button and pushing down on the tube.
Attaching Extension Cord
► An extension cord retainer
(Fig. G)
is built into the switch
handle that prevents the cord from coming unplugged.
To use this feature, simply double the extension cord
about 8 inches (203mm) from the end, and insert it into
the slot in the bottom of the handle area. Hook the loop
formed by doubling the cord over the tab. Gently tug on
the cord to insure that it is firmly retained in the trimmer’s
handle. Plug the receptacle end of the extension cord into
the plug blades in the trimmer.
OPERATING INSTRUCTIONS
Warning!
Always use proper eye protection that conforms
to ANSI Z87.1 (CAN/CSA Z94.3) while operating this power tool.
Caution!
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 tool,
such as barbs at the base of a chain link fence.
Switching On and Off
► To switch the tool on, squeeze the trigger lever.
► To switch the tool off, release the trigger lever.
► With the unit on, angle unit and slowly swing the trimmer
side to side as shown in
Fig. H.
► To operate as a maintenance edger, unplug the unit from
the power source. Push the button and rotate the tube
180° as shown in
Fig. F.
The tool will lock in position.
Gently pull the wire edge guide down into place as shown
in
Fig. I
and position the trimmer above the surface as
shown in
Fig. I.
► Return to the trimming position by unplugging the unit
from the power source, pushing the button and rotating
the tube back 180°. The tool will lock in the trimmer
position. When using the tool return the wire edge guide
to the original position, out of the way.
Blower Function
The GH750 funnels the air created by the motor up through the
guard creating a built-in sweeper. This feature can be used to
blow grass clippings off of sidewalks and other hard surface areas.
Cutting Line/Line Feeding
Your trimmer uses .065 inch (1.65 mm) diameter,
round
nylon
line. During use, the tips of the nylon lines will become frayed
and worn and the special self feeding line hub will automatically
feed and trim a fresh length of line. Cutting line will wear faster
and require more feeding if the cutting or edging is done along
sidewalks or other abrasive surfaces or heavier weeds are
being cut. The advanced automatic line feeding mechanism
senses when more cutting line is needed and feeds and trims
the correct length of line whenever it’s required.
Do not bump
unit on ground in attempt to feed line or for any other purposes.
Fitting a New Spool of AFS Cutting Line (Figs. J & K)
► Unplug the tool.
► Depress the tabs
(1)

position before inserting new spool into cassette.
