CHARGING THE BATTERY

Before attempting to charge the battery pack, thoroughly read all safety instructions.

NOTE:

The battery pack is not fully charged at the factory. 

CHARGE THE BATTERY BEFORE THE

INITIAL USE.

1. Plug the battery charger into any standard 120 Volt 60

Hz electrical outlet.

IMPORTANT:

Do not charge by means of an engine

generator or DC power source. Use only 120V AC.

2. Slide the battery onto the battery charger (Fig. 1). Both

LEDs will illuminate. Let the battery charge until the red
LED flashes. 

3. Unplug the charger. Slide the battery off the battery

charger (Fig. 1).

Important Charging Notes

• After the initial charge, under normal usage, the battery

pack should be fully charged in 1.5 hours. 

NOTE:

A hot battery placed in the charger will not charge. Allow the battery to cool down for 30
minutes before charging after using the unit.

DO NOT

charge the battery pack in an air temperature below 32°F (0 °C) or above 104°F (40 °C). This

is important and will prevent serious damage to the battery pack. Longest life and best performance
can be obtained if battery pack is charged when air the temperature is about 75°F (24°C).

• While charging, the charger may hum and become warm to the touch. This is a normal condition

and does not indicate a problem.

• If the battery pack does not charge properly:

1. Check the current at the receptacle by plugging in a lamp or other appliance.
2. Check to see if the receptacle is connected to a light switch that turns power off to the

receptacle when the light switch is turned off.

3. Move the charger and battery pack to a surrounding air temperature of 32°F (0°C) to 104°F (40 °C).
4. If the receptacle and temperature are OK, and the battery still does not charge properly, call

1-866-206-2707

(U.S.) or 

1-877-696-5533

(Canada) for assistance.

• Lithium-ion batteries, while in use, will continue to provide full power without power fade, unlike

typical batteries; when the battery is fully discharged, the battery circuitry will immediately cut
power to the tool and require immediate charging.

• To prolong battery life, avoid leaving the battery pack on the charger for extended periods (over 30

days without use). Although overcharging is not a safety concern, it can significantly reduce battery life.

• The battery pack will reach optimum performance after 5 cycles of normal usage. There is no need

to run the batteries down completely before recharging. Normal usage is the best method of
discharging and recharging the batteries.

OPERATING INSTRUCTIONS

PROPER GRIP

• Always grip the unit firmly with both hands when the motor is running. Keep the left hand on the front

handle and the right hand on the rear handle. Use a firm grip with thumbs and fingers encircling the
handles. This grip is least likely to be broken. Any grip in which the thumb and fingers 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.

PROPER STANCE

• Balance body weight securely, with both feet on solid

ground (Fig. 4).

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 7/16 of an inch (11.1 mm). For larger branches, use a non-powered saw or pruning saw.

• Work slowly, while maintaining a proper grip and stance  (Fig. 4).
• 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 efficiency. Forcing
the unit can also result in damage to the blade and can increase the chance of personal injury.

• When trimming new growth, use a wide sweeping action, so that stems are fed directly into the

trimmer blade (Fig. 5). Older growth will have thicker stems and will be trimmed easiest by using a
sawing motion.

• Release the switch trigger 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. Leave this operation for professionals.
• Do not cut above chest height, as a hedge trimmer held higher is more difficult to control.

WARNING:

If any parts are damaged or missing, do not operate the unit until the parts

are replaced. Failure to heed this warning could result in serious personal injury.

WARNING:

Always wear appropriate eye and ear/hearing protection when operating this

unit. Wear safety goggles, or safety glasses with side shields, that are marked as meeting
ANSI Z87.1-1989 standards. Failure to do so could result in serious eye injury caused by
thrown objects. If the operation is dusty, wear a facemask or dust mask.

WARNING:

Do not allow familiarity with this unit to promote carelessness. Remember that a

careless fraction of a second is enough to inflict serious injury.

WARNING:

Wear non-slip gloves for maximum grip and protection. Refer to the 

Safety

Information

section for appropriate safety equipment.

WARNING:

Do not expose the unit to rain. Do not use the unit in damp or wet locations

or conditions.

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 the

trimmer blade is moving. Do not grasp the trimmer blade when picking up or holding the
unit. Make sure the battery is removed and the switch lock is in the locked or OFF position
before clearing any jammed material from the trimmer blade.

Fig. 5

WARNING:

Before inspecting, cleaning or servicing the unit, stop the motor, make sure

the switch lock is in the locked or OFF position, wait for all moving parts to stop, allow the
unit to cool and remove the battery from the unit. Failure to follow these instructions can
result in serious personal injury or property damage.

MAINTENANCE AND REPAIR INSTRUCTIONS

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, ensure that the switch lock is in the locked or OFF

position, remove the battery and lubricate the trimmer blade as needed.

1. Apply light machine oil along the edge of the top blade (Fig. 6).

CHARGER MAINTENANCE

• To ensure safety and reliability, all repairs should be performed by a qualified service technician.
• Check that the charger contacts have not been shorted by debris or foreign material.

Fig. 6

WARNING:

To avoid possible serious injury, never touch or adjust the trimmer blade

while the motor is running. The trimmer blade is very sharp; always wear protective gloves
when performing maintenance to the trimmer blade.

CAUTION:

Some spray-on lubricants contain solvents and will cause some types of

grease to break down. To prevent damage to the unit, only use a high-quality machine oil.
