Check for damaged parts. Before further use of the

alignment of moving parts, binding of moving parts,
breakage of parts, mounting, and any other condition
that may effect the units operation. A guard or other
part that is damaged should be properly repaired or
replaced by an authorized service dealer unless
indicated elsewhere in this manual.
AFTER EACH USE CLEAN UNIT
AND LABELS
Clean the unit using a damp cloth with a mild
detergent.
NOTE: Do not use any strong detergents on the plastic
housing or the handle. They can be damaged by
certain household cleaners that contain aromatic
oils such as pine and lemon, and by solvents
such as kerosene.
WARNING: Do not at any time let brake
fluids, gasoline, petroleum-based products,
penetrating oils, etc. come in contact with
plastic parts. They contain chemicals that
can damage, weaken, or destroy plastic.
Wipe off the unit with a clean, dry, soft cloth.
Keep handles dry, clean and free from oil and grease
at all times.
SHARPENING THE CUTTER BLADE
WARNING: During these procedures, you will
need to connect the unit to power. To avoid
serious personal injury, be sure to disconnect
the power when stated.
1. Allow your hedge trimmer to come to a stop with the
cutter blade and guard positioned as shown in
Figure 8. This will allow clearance for the file
between cutter teeth and guard teeth.
2. Disconnect Hedge Trimmer from power supply.

BLADE LUBRICATION
Disconnect hedge trimmer from power supply.
For easier operation and longer blade life, lubricate the
hedge trimmer blade before and after each use. Before
lubricating, be sure the switch is in the off position and
the tool is disconnected from the power supply. Apply
light machine oil along the edge of the top strap as
shown in figure 9.
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 quality machine oil.
Your trimmer should be stopped, disconnected, and
oiled occasionally during use.
3. Clamp the blade assembly in a vise and file the
exposed cutting surface of each blade tooth with an
8 inch fine round file, 1/4 in. or 7/32 in. diameter. Be
sure to retain the original angle of tooth when filing.
4. Remove the hedge trimmer from the vise, restart it,
and stop it so that the unsharpened edges of the
blade teeth are exposed.
5. Disconnect the tool and repeat the sharpening
procedure as described above.
