SHARPENING BLADE
Allow the blades of hedge trimmer to come to a
stop in the position shown in Figure 11 . This will
allow clearance for the file between cutter teeth and
guard teeth.
CUTTER BLADE
Remove battery pack from hedge trimmer.
Clamp blade assembly in a vise and file the
exposed cutting surface of each blade tooth with an
8 inch smooth round file, 1/4 inch or 7/32 inch
diameter. Be sure to retain the original angle of
tooth when filing.
Remove the hedge trimmer from the vise, replace
battery pack and restart the hedge trimmer. Allow
the blades of the hedge trimmer to come to a stop
so that the unsharpened edges of the cutter blade
teeth are exposed.
Remove battery pack from hedge trimmer and
repeat the sharpening procedure as described
above.
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.

BATTERIES
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 tem-
perature will shorten battery pack life.
Never store batteries in a discharged condition.
Wait for battery pack to cool and charge immedi-
ately.
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.
WARNING:
Do not attempt to disassemble the battery pack.
Fire or injury can result.
WARNING:
Do not attempt to modify this unit or create or
mount any accessory not specifically recom-
mended 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).
