3. BEFORE plugging in the tool, BE SURE that the outlet voltage supplied is within the
voltage marked on the tool’s data plate. DO NOT use “AC only” rated tools with a DC
power supply.
4. MAINTAIN hedge trimmer with care. Keep cutting blades sharp and clean for best
performance and to reduce the risk of injury. Inspect extension cord periodically and
replace if damaged. Keep handles dry, clean and free from oil and grease.
4. DO NOT expose tools to rain or wet conditions or use electric tools in wet or damp
locations. Water entering an electric tool will increase the risk of electric shock.
5. CHECK for misalignment or binding of moving parts, breakage of parts, and any
other condition that may affect the tool's operation. If damaged, have the tool serviced
before using. Many accidents are caused by poorly maintained tools.
5. If operating an electric tool in damp locations is unavoidable, ALWAYS USE a
Ground Fault Circuit Interrupter to supply power to your tool. ALWAYS WEAR
electrician’s rubber gloves and footwear in damp conditions.
6. ALWAYS INSPECT the hedges, bushes, plantings that you are going to trim for hidden
wires, pipe, landscape boards or other obstructions that could get caught in, or damage
the cutting bar or blades.
6. When operating a power tool outside, ALWAYS use an outdoor extension cord marked

7. INSPECT tool cords for damage. Have damaged tool cords repaired at a Sears
Service Center. BE SURE to stay constantly aware of the cord location and keep it well
away from the blades.
NOTE: IMPORTANT Lubricate the blades before and after each use. Ignoring
lubrication will shorten blade life and affect cutting operation.
8. DO NOT abuse the cord. NEVER use the cord to carry the tool by or to pull
the plug from the outlet. Keep cord away from heat, oil, sharp edges or moving parts.
Replace damaged cords immediately. Damaged cords increase the risk of electric shock.

1. Double insulated tools are equipped with a polarized
plug (one blade is wider than the other). This plug
will fit in a polarized outlet only one way. If the plug
does not fit fully in the outlet, reverse the plug. If it still does
not fit, contact a qualified electrician to install a polarized
outlet. Do not change or alter the plug in any way.
When operating a power tool outdoors, use only with an outdoor extension cord
marked “W-A” or “W”. These cords are rated for outdoor use and reduce the risk
of electric shock.

grounded power supply system. Applicable only to Class II (double-insulated) tools.
This tool is a double insulated tool.

OPERATION cont.
OPERATION cont.
USING THE TRIMMER (Figs. 6, 7 and 8) cont.
USING THE TRIMMER (Figs. 6, 7 and 8)
6. When trimming new growth, use a wide sweeping motion (see Fig. 8), so the stems
are fed directly into the cutting blade. A slight downward tilt of the blade in the direction
of motion gives the best cutting.
NOTE: Always keep the power cord behind the hedge trimmer when in use.
Do not place it over the hedge where it may be cut.
7. Older growth will have thicker stems and should be trimmed using a back and forth
sawing motion.
1. Always hold the hedge trimmer firmly with both hands. Maintain proper footing and
balance and do not overreach (see Fig. 6).
8. LEVEL HEDGES - To obtain exceptionally level hedges, a piece of string can be
stretched along the edge of the hedges as a guide (see Fig. 7).
2. Before cutting an area, inspect if first and remove any foreign objects that could
become thrown or entangled in the blades.
9. SIDE TRIMMING HEDGES - To side-trim hedges, begin at the bottom of the hedge
and sweep upward (see Fig. 6).
3. ALWAYS hold the hedge trimmer with one hand on the front handle and one on the
rear handle and with the blade away from
you before turning it on. NEVER hold the
trimmer by the blade safety guard.
Fig. 7
Fig. 8
4. DO NOT try to trim too much at one time.
This can cause the blades to bind and slow
down, reducing the cutting efficiency.
Fig. 6
!
WARNING: To help guard against injury, always observe the following rules.
• Read operator’s manual before each use. Save manual.
• Always check Blade Safety Guard to make sure it is locked tightly and
securely in position before using the trimmer
• Keep hands away from blades, behind the blade safety guard.
• Keep hands on handles. Do not overreach.
• Do not use in wet conditions.
!
DANGER: If the blade jams on any electrical cord or line, DO NOT TOUCH
THE BLADE. IT CAN BECOME ELECTRICALLY LIVE AND BE VERY DANGEROUS.
Continue to hold your trimmer by the insulated handles and immediately
disconnect the damaged electrical cord or line from the power source. Failure to
heed this warning will result in serious or fatal personal injury.
• Do not use with damaged extension cords.
• Never immerse any part of the tool into a liquid.
5. ALWAYS wear heavy-duty rubber gloves when trimming; they will help protect your
hands from thorny or prickly growth.
!
CAUTION: Blade coasts after turn off. Do not put your hands anywhere
near the blades until they come to a complete stop and you have disconnected
trimmer from power source.
!
CAUTION: DO NOT try to cut branch stems that are larger than 3/4-in (19mm)
thick or those obviously too large to feed into the cutting blade. Use the hedge
trimmer for cutting normal hedges and shrubbery only. Use a hand saw or pruning saw
to trim large branches.
!
WARNING: DO NOT use this hedge trimmer with any type of accessory or
attachment. Such usage might be hazardous.

WARNING: Your hedge trimmer should NEVER be connected to the
power source when you are assembling parts, making adjustments, oiling
blades, cleaning or when it is not in use. Disconnecting the trimmer will prevent
accidental starting, which could cause serious personal injury,
4. Remove the hedge trimmer from the vise, connect to power, restart trimmer to expose
any other part of the cutting blade you need to file, stop trimmer, and disconnect trimmer
from the power supply.
5. Repeat the above process of filing and moving the blade teeth until you have removed the
nick and sharpened the tooth.
Periodic maintenance allows for long life and trouble-free operation. A cleaning and
maintenance schedule should be maintained. As a common preventive maintenance
practice, follow these recommended steps:
!
WARNING: Do not at any time let brake fluids, gasoline, petroleum-based
products, penetrating oils, etc., come in contact with plastic parts. Chemicals
can damage, weaken or destroy plastic which may result in serious
personal injury.
1. When work has been completed, always clean and oil the cutting blades, and clean
the tool to allow smooth functioning of the tool over time. Also keep the air vents free
of obstructions.
2. Clean the tool with a small brush. Wipe off any moisture with a soft cloth.
3. Keep the motor air openings free from oil, grease, leaves, stems or woodchips,
and store tool in a dry place.
LUBRICATING THE BLADE (Fig. 10)
!
WARNING: To avoid injury, ALWAYS turn off and disconnect the trimmer
SHARPENING AND REMOVING NICKS FROM THE BLADES (Fig. 9)
from the power outlet BEFORE installing parts, cleaning the trimmer or making
any adjustments.
The cutting blades are made from high quality, hardened
steel and with normal usage, they will not require re-sharpening.
However, if you accidentally hit a wire fence, stone or brick wall
or some other hard objects, you may put a nick in the blade.
There is no need to remove the nick as long as it does not
interfere with the movement of the blade’s dual action.
To remove nicks or sharpen the blades, follow these
recommended steps:
Fig. 9
For efficient operation and longer blade life, always clean and lubricate the hedge trimmer
blade before and after each use. Before lubricating, be sure the unit is turned OFF and
unplugged from the power supply. Apply a premium light machine oil along the edge of
the top strap (see Fig. 10).
