WARNING
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, service or for changing the
cutting blade.
WARNING
To prevent serious personal injury, remove
the battery pack before servicing, cleaning,
or removing material from the unit.
BLADE CARE
Lubricate the cutting blades after each use.
■
Periodically inspect the blades for damage and wear.
■
Always use the manufacturer's specified replacement
■
blades.
TO LUBRICATE BLADE
Remove battery pack from hedge trimmer.
■
For easier operation and longer blade life, lubricate the
■
hedge trimmer blade before and after each use. Before
lubricating, remove the battery pack and lay hedge
trimmer on a flat surface. Apply light weight machine oil
along the edge of the top blade. See Figure 8.
Occasionally, you should oil your hedge trimmer during
■
use. Before oiling, stop hedge trimmer, remove battery
pack, then oil. You then can resume trimming. Do not oil
while hedge trimmer is running.
SHARPENING BLADE
Allow the blades of hedge trimmer to come to a stop in
■
the position shown in Figure 9. This will allow clearance
for the file between cutter teeth and guard teeth.
Remove battery pack from hedge trimmer.
■
Clamp blade assembly in a vice and file the exposed
■
cutting surface of each blade tooth with an 203 mm
(8 inch) smooth round file, 6.4 mm (1/4 inch) or
5.6 mm (7/32 inch) diameter. Be sure to retain the
original angle of tooth when filing.
Remove the hedge trimmer from the vice, 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.
