W ARNING:
Always keep both hands on your hedge trimmer
handles. Never hold shrubs with one hand and
operate hedge trimmer with the other. Failure to
heed this warning will result in serious injury.
OPERATING TIPS
• Before starting your hedge trimmer, hold the unit
with both hands with the cutting blades directed
away from you. Always use your hedge trimmer
properly.
• Do not force the hedge trimmer through heavy
shrubbery. This can cause the blades to bind and
slow down. If the blades slow down, reduce the
pace.
• Do not try to cut stems or twigs that are larger than
3/8 inch thick, or those obviously too large to feed
into the cutting blade. Use a non-powered hand saw
or pruning saw to trim large stems.
Fig. 6
Fig. 7
• Wear gloves when trimming thorny or prickly
growth. When trimming new growth, use a wide
sweeping action, so that the stems are fed directly
into the cutting blade. Older growth will have thicker
stems and will be trimmed easiest by using a
sawing movement.

HEDGE TRIMMER LUBRICATION
All of the bearings in this tool are lubricated with a
sufficient amount of high-grade lubricant for the life of
the unit under normal operating procedures. Therefore,
no further lubrication is required.
BA TTERIES
Your battery pack is equipped with Nickel-Cadmium
rechargeable batteries. Length of service from each
charging will depend on the type of work you are doing.
The batteries in this unit have been designed to
provide maximum trouble-free life. However, like all
batteries, they will eventually wear out. DO NOT
disassemble battery pack and attempt to replace the
batteries. Handling of these batteries, especially when
wearing rings and jewelry, could result in serious burn.
To obtain the longest possible battery pack life, we
suggest the following:
• Store and charge your batteries in a cool area.
Temperatures above or below normal room temperature will shorten battery pack life.
• Never store batteries in a discharged condition.
Wait for battery pack to cool and charge immediately.
• All batteries gradually lose their charge. The higher
the temperature, the quicker they lose their charge.
If you store your unit for long periods of time
without using it, recharge the batteries every month
or two. This practice will prolong battery pack life.
W ARNING:
Do not attempt to disassemble the battery pack.
Fire or injury can result.
W ARNING:
Do not attempt to modify this unit or create or
mount any accessory not specifically recommended in this manual for use with this hedge
trimmer. Any such alteration or modification is
misuse and could result in a hazardous condition
leading to possible serious personal injury.
CAUTION:
Any repairs requiring disassembly should only be
performed by a Homelite Authorized Service
Center. For the repair center nearest you, call
1-800-chainsaw (1-800-242-4672).

• Use a small brush or the air discharge of a small
vacuum cleaner brush to clean the air vents on the
battery pack housing and motor housing.
• Keep the air vents free of obstructions.
STORING THE HEDGE TRIMMER
• Clean the hedge trimmer thoroughly before storing.
Store the hedge trimmer in a dry, well-ventilated
place that is inaccessible to children. Keep away
from corrosive agents such as garden chemicals
and de-icing salts.
• Always place blade cover on cutting blades before
storing.

BLADE COVER
.
W ARNING:
Examine hedge trimmer frequently to assure all
parts are unbroken and securely attached. Make
sure all screws and fasteners are securely tightened to prevent the risk of serious personal injury.
CLEANING THE HEDGE TRIMMER
W ARNING:
Battery units do not have to be plugged into an
electrical outlet; therefore, they are always in
operating condition. To prevent serious personal
injury, always remove the battery and take extra
precautions and care when performing maintenance,
cleaning or servicing the unit.
W ARNING:
To prevent serious personal injury, remove the
battery pack before servicing, cleaning, or removing
material from the unit.
Fig. 12
• Store and charge your batteries in a cool area.
Temperatures above or below normal room temperature will shorten battery pack life.
• Never store batteries in a discharged condition.
Wait for battery pack to cool and charge immediately.
• All batteries gradually lose their charge. The higher
the temperature, the quicker they lose their charge.
If you store your unit for long periods of time
without using it, recharge the batteries every month
or two. This practice will prolong battery pack life.
