MAINTENANCE AND REPAIR INSTRUCTIONS

WARNING: To avoid serious personal injury,
always turn your trimmer off and unplug it
before you clean or service it.
SERVICING DOUBLE INSULATED UNITS
This unit is double-insulated. In a double-insulated unit,
two systems of insulation are provided instead of
grounding. There is no grounding provided and no
means of grounding should be added to this unit.
Extreme care and knowledge of the system is required
when servicing a double-insulated unit. Service should
be performed by qualified service personnel only.
Replacement parts for a double-insulated unit must be
identical to the parts they replace. Refer any repair to an
authorized service dealer. A double-insulated unit is
marked with the words "double insulation" or "double
insulated."
CLEANING
Switch off the unit and disconnect it from the power
source. Use a small brush to clean off the outside of the
unit. Do not use strong detergents. Household cleaners
that contain aromatic oils such as pine and lemon, and
solvents such as kerosene, can damage plastic housing
or handle. Wipe off any moisture with a soft cloth. Also
keep the air vents free of obstructions.
INSPECT EXTENSION CORDS
Inspect all extension cords. Look closely for deterioration,
cuts or cracks in the insulation. Inspect the connectors for
damage. Replace a damaged or defective cord.
STORAGE
• Allow the unit to col before storing.
• Lock the unit to prevent unauthorized use or damage.
• Store the unit in a dry, well-ventilated area.
• Store the unit out of the reach of children.
CHECK FOR DAMAGED/WORN PARTS
Before each use, check for damaged parts. Before
further use of the unit, a guard or other part that is
damaged should be carefully checked to determine that
it will operate properly and perform its intended function.
Check for 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.
WARNING: You will need to connect the
unit to power during these procedures. To
avoid serious personal injury, be sure to
pay attention to the instructions and
DISCONNECT the power when stated.

SHARPENING THE BLADE
1. Allow your hedge trimmer to come to a stop with the
cutter blade and guard positioned as shown in
Figure 11. This will allow clearance for the file
between cutter teeth and guard teeth.
2. Disconnect the hedge trimmer from the power supply.
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, with a 1/4 or 7/32 inch
diameter. Be sure to retain the tooth's original angle
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 pro-
cedure as described above.
Cutting Blade
LUBRICATING THE BLADE
To lubricate the cutting blade, disconnect the hedge
trimmer from the power supply.
For easier operation and longer blade life, lubricate the
hedge trimmer blade before and after each use. Before
lubricating, be sure the unit is off and disconnected from
the power supply. Apply light machine oil along the edge
of the top strap (Fig. 12).
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.
Occasionally stop, disconnect, and oil your trimmer
during use.
