FOR FUTURE USE

• AVOID DANGEROUS ENVIRONMENT

- Don’t use hedge trimmers in damp or
wet locations.

• DON’T USE IN RAIN.

• KEEP CHILDREN AWAY - All visitors
should be kept at a safe distance from
the work area.

• DRESS PROPERLY - Don’t wear loose
clothing or jewelry. They can be caught
in moving parts. Use of rubber gloves
and substantial footwear is
recommended when working outdoors.
Wear protective hair covering to contain
long hair.

• USE SAFETY GLASSES - Also use face
or dust mask if operation is dusty.

• GROUND FAULT CIRCUIT
INTERRUPTER (GFCI) protection
should be provided on the circuit(s) or
outlet(s) to be used for the hedge
trimmer. Receptacles are available
having built-in GFCI protection and may

SJOW-A, SJTW-A or SJTOW-A.

• EXTENSION CORD. Make sure your
extension cord is in good condition.
When using an extension cord be sure it
is heavy enough to carry the current
your product will draw. An undersized
extension cord will cause a drop in line
voltage resulting in loss of power and
overheating. The following table shows
the correct size to use depending on
cord length and nameplate ampere
rating. If in doubt, use the next heavier
gage. The smaller the gage number, the
heavier the cord.

• AVOID UNINTENTIONAL STARTING -
Don’t carry plugged in hedge trimmer

To reduce the risk of electric shock, this
equipment has a polarized plug (one
blade is wider than the other). This
equipment must be used with a suitable
polarized 2 wire or 3 wire extension cord.
Polarized connections will fit together
only one way. Make sure that the
receptacle end of the extension cord has

large and small blade slot widths. If the
plug does not fit fully into the extension
cord, reverse the plug. If it still does not
fit, obtain a suitable extension cord. If the
extension cord does not fit fully into the
outlet, contact a qualified electrician to
install the proper outlet. Do not change
the tool plug or extension cord in any way.

• CHECK DAMAGED PARTS - before
further use of the hedge trimmer, 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 affect its operation. A
guard or other part that is damaged

should be properly repaired or replaced
by an authorized service center unless
otherwise indicated elsewhere in this
manual.

DANGER: Laceration hazard. Keep
hands away from blades. Keep both
hands on handles when power is on.

CAUTION: Laceration hazard. Blades
coast after turn off.

SAFETY WARNINGS: DOUBLE INSULATION

Double insulated tools are constructed
throughout with two separate layers of
electrical insulation or one double
thickness of insulation between you and
the tool’s electrical system. Tools built
with this insulation system are not
intended to be grounded. As a result,
your tool is equipped with a two prong
plug which permits you to use extension
cords without concern for maintaining a
ground connection.

NOTE: Double insulation does not take
the place of normal safety precautions
when operating this tool. The insulation
system is for added protection against
injury resulting from a possible electrical
insulation failure within the tool.

Replacement parts: When servicing all
tools, USE IDENTICAL REPLACEMENT
PAR TS. Repair or replace damaged
cords.

inches (203 mm) from the end, and insert
it into the slot in the bottom of the handle
area. Hook the loop formed by doubling
the cord over the tab, as shown in figure

8. Gently tug on the cord to insure that it
is firmly retained in the trimmer’s handle.
Plug the receptacle end of the extension
cord into the plug blades in the trimmer

TRIMMING INSTRUCTIONS

1. EXTENSION CORD – (Figure 8 &

10) Always keep extension cord

behind trimmer and away from the
trimming operation. Never drape it
over a hedge being trimmed. If you
cut or damage the cord, unplug it at
the electrical outlet immediately,
before inspecting or repairing cord.

4. WORKING POSITION – (Figure 10)

Maintain proper footing and balance
and do not overreach. Wear safety
goggles, non-skid footwear and
rubber gloves when trimming. Hold
the tool firmly in both hands and turn
the tool ON. Always hold the trimmer,
with one hand on the switch handle
and one hand on the bail handle.
Never hold the tool by the blade guard.

3. TRIMMING NEW GROWTH -

(Figure 11) – A wide, sweeping motion,
feeding the blade teeth through the
twigs is most effective. A slight
downward tilt of the blade, in the
direction of motion gives the best
cutting.

CAUTION: Do not use the trimmer for
cutting stems greater than its capacity.
Use the trimmer only for cutting normal
shrubbery found around houses and
buildings.

79442, 51891 5/8 in. (8mm)

4. LEVEL HEDGES (Figure 12) – To

obtain exceptionally level hedges, a
piece of string can be stretched along
the length of the hedge as a guide.

With the unit unplugged, use only mild
soap and a damp cloth to clean the tool.
Never let any liquid get inside the tool;
never immerse any part of the tool into a
liquid.

IMPORTANT: To assure product SAFETY
and RELIABILITY, repairs, maintenance
and adjustment should be performed by
Sears service centers or other qualified
service personnel, always using identical
replacement parts.

WARNING: DO NOT use the hedge

trimmer with any type of accessory or
attachment. Such usage might be
hazardous.

5. SIDE-TRIMMING HEDGES -

(Figure 13)

Begin at the bottom and sweep up.

WARNING

: To guard against injury

observe the following:

• Read instruction manual before using,
Save instruction manual.

• Keep hands on handles. Don’t overreach.

• Do not use under wet conditions.

• Do not use with damaged extension
cords.

• Do not unplug or store with switch
locked on.

DANGER: KEEP HANDS AWAY

FROM BLADES.

CAUTION: BLADE COASTS AFTER

TURN OFF.

The cutting blades are made from high
quality, hardened steel and with normal
usage, they will not require resharpening.
However, if you accidentally hit a wire
fence, stones, glass or other hard objects,
you may put a nick in the blade. There is
no need to remove this nick as long as it
does not interfere with the movement of
the blade. If it does interfere, unplug unit
and while wearing proper eye protection
use a fine toothed file or sharpening stone
to remove the nick.

If you drop the trimmer, carefully inspect it
for damage. If the blade is bent, housing
cracked, or handles broken or if you see
any other condition that may affect the
trimmer’s operation, contact your local
Sears Service Center for repairs before
putting it back into use.

Fertilizers and other garden chemicals
contain agents which greatly accelerate
the corrosion of metals. Do not store the
tool on or adjacent to fertilizers or
chemicals.
