• 

When trimming new growth, use a wide sweeping 
action, so that stems are fed directly into the 
trimmer blade (Fig. 6). Older growth will have thicker 
stems and will be trimmed easiest by using a 
sawing motion.

• 

Release the switch trigger(s) as soon as the cut is 
completed. Allow the trimmer blade to come to a 
complete stop. Unnecessary wear may occur if the 
unit is run without a cutting load.

• 

After completing the cut, wait for the trimmer blade 
to stop before moving the unit. Always stop the 
motor before moving from hedge to hedge.

• 

If desired, use a string to help cut hedges level. Determine the desired height of the hedge, then 
stretch a length of string along the hedge at that height. Trim the hedge to just above the string 
line. Trim the side of the hedge so that it will be slightly narrower at the top. More of the hedge will 
be exposed when shaped this way, and it will appear more uniform.

• 

Do not cut from a ladder; this is extremely dangerous.

• 

Do not cut above shoulder height, as a hedge trimmer held higher is more diffi cult to control.

Disconnecting the Power Source

1.  Disconnect the extension cord plug from the outlet.

NOTE:

 

DO NOT

 pull the cord out of the wall. Always 

remove the cord from the power source by 
the plug head.

2.  Remove the loop in the extension cord from the 

cord hook (Fig. 2).

3.  Disconnect the power cord plug from the extension 

cord (Fig. 1).

HOLDING THE UNIT

• 

Hold the unit fi rmly with both hands. Always keep 
one hand on the front handle and the other hand on 
the rear handle (Fig. 5).

• 

Maintain a proper grip on the unit whenever the 
motor is running. The fi ngers should encircle the 
handle and the thumb should wrap under the 
handle. This grip is least likely to be broken. Any 
grip in which the thumb and fi ngers are on the same 
side of the handle is dangerous because a slight 
kick of the unit can cause loss of control.

• 

Keep hands away from the trimmer blade. Keep 
both hands on the handles and behind the protective guard whenever the motor is running.

• 

Balance body weight securely, with both feet on solid ground (Fig. 5).

WORK AREA PRECAUTIONS

• 

Keep everyone – helpers, bystanders, children and animals – at least 50 feet (15 m) away from the 
work area. If anyone enters the work area, stop the unit!

• 

Only operate the unit when visibility and light are adequate to see clearly.

• 

Keep the work area clean. Do not start the operation until the work area is clear and free from 
obstructions. Remove all cords, lights, wires, strings or other objects that could become entangled 
in the trimmer blade.

BASIC OPERATING PROCEDURES

IMPORTANT:

 Lubricate the trimmer blade before and after each use. Ignoring this step will decrease 

the life of the trimmer blade and hamper operation. Refer to 

Maintenance and Repair 

Instructions

.

• 

Use the hedge trimmer for trimming and forming hedges, shrubs and bushes with a branch 
diameter of up to 3/4 of an inch  (19 mm). For larger branches, use a non-powered saw or pruning 
saw.

• 

Work slowly, while maintaining a proper grip and stance.

• 

Allow the unit to do the cutting. Forcing the unit through dense growth, or attempting to trim too 
much at one time, can cause the blade to bind and slow, reducing the cutting effi ciency. Forcing 
the unit can also result in damage to the blade and can increase the chance of personal injury.

 STARTING THE UNIT

To help prevent accidental start-ups, this unit has a front 
handle switch trigger and a rear handle switch trigger 
that must be used together to start the unit. 
1.  Connect the unit to the power source. Refer to 

Connecting the Power Source

.

2.  Hold the front handle with one hand and squeeze 

the front handle switch trigger (Fig. 4). 

3.  Hold the rear handle with the other hand and 

squeeze the rear handle switch trigger (Fig. 4). The 
unit should start immediately.

4.  Continue to squeeze both switch triggers for continued operation. 

STOPPING THE UNIT

1.  Release one or both of the switch triggers.

NOTE:

 

It is normal for the trimmer blade to coast to a stop once a switch trigger is released.

 MAINTENANCE

Follow all maintenance instructions in this manual.

NOTE:

 

All service, other than the maintenance procedures described in this manual, should be 
performed by an authorized service center. Do not attempt to repair; there are no user 
serviceable parts inside.

Before inspecting, servicing, cleaning, storing, transporting or replacing any parts on the unit, make sure:

1.  The switch triggers are released.
2.  All moving parts have stopped.
3.  The unit is disconnected from the power source.
4.  The unit is cool.

SHARPENING THE BLADE

The cutting blades are made from high-quality, hardened steel and with normal usage will not require 
sharpening. However, if the trimmer blade accidentally hits wire fencing, stones, glass, nails or other 
hard objects, the blade may become nicked. There is no need to remove this nick unless it interferes 
with the movement of the trimmer blade. If it does interfere, or if the performance of the unit has 
diminished due to blade dullness, have the trimmer blade sharpened by an authorized service center.

LUBRICATING THE BLADE

• 

For easier operation and longer blade life, lubricate 
the trimmer blade before and after each use.  

• 

During use, occasionally stop the motor and 
lubricate the trimmer blade as needed. Ensure 
that the switch triggers are released and the unit is 
unplugged prior to lubricating the blade.

1.  Apply light machine oil along the edge of the top 

blade (Fig. 7).

DANGER:

 If the trimmer blade gets caught on an electrical cord or wire, DO 

NOT TOUCH THE BLADE! IT MAY BE ELECTRICALLY LIVE AND EXTREMELY 
DANGEROUS. Release the trimmer in the quickest and safest way. If possible, 
disconnect the damaged electrical cord or wire from its power source. If that is not 
possible, call an electrician, electrical contractor, or the power company for assistance. 
Failure to heed this danger warning will cause serious personal injury or possible death.

WARNING:

 Do not attempt to remove cut material or hold material to be cut while
