that is damaged should be carefully checked to determine that it will operate properly and
perform its intended function. Check for alignment of moving parts, binding of moving
parts, breakage of parts, mounting, and any other condition that may affect its operation. A
guard or other part that is damaged should be properly repaired or replaced by an
authorized service center unless otherwise indicated elsewhere in this manual.
WARNING: When servicing double insulated tools, USE ONLY IDENTICAL
REPLACEMENT PARTS. Replace or repair damaged cords.
WARNING: To prevent electrical shock hazard, use only with an extension cord
suitable for outdoor use. Always connect extension cords to a fused line or one protected
by a circuit breaker.
ADDITIONAL WARNINGS FOR STRING TRIMMERS
1. DO NOT immerse tool in water or squirt it with a hose. DO NOT allow any liquid to get
inside it.
2. Do not store the tool on or adjacent to fertilizers or chemicals.
3. DO NOT clean with a pressure washer.
SAFETY WARNINGS AND INSTRUCTIONS: POLARIZED PLUGS
To reduce the risk of electric shock, this equipment has a polarized plug (one blade is wider
than the other) and will require the use of a polarized extension cord. The appliance plug will
fit into a polarized extension cord only one way. If the plug does not fit fully into the extension
cord, reverse the plug. If the plug still does not fit, obtain a correct polarized extension cord.
A polarized extension cord will require the use of a polarized wall outlet. This plug will fit into
the polarized wall outlet only one way. If the plug does not fit fully into the wall outlet, reverse
the plug. If the plug still does not fit, contact a qualified electrician to install the proper wall
outlet. Do not change the equipment plug, extension cord receptacle, or extension cord plug
in any way.
SAFETY WARNINGS AND INSTRUCTIONS: EXTENSION CORDS
Make sure your extension cord is in good condition. When using an extension cord, be sure
to use one heavy enough to carry the current your product will draw. An undersized cord will
cause a drop in line voltage resulting in loss of power and overheating.

plastic knob as shown in figure 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 figure 6
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 (figure 7) 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.

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.
