INTRODUCTION

Your hedge trimmer has many features for making trimming operations more pleasant and enjoyable. Safety, performance and dependability have been
given top priority in the design of this hedge trimmer
making it easy to maintain and operate.
A Look for this symbol to point out important safety precautions. It means attention!!! Your
safety is involved.
CAUTION: Carefully read through this entire
owner's manual before using your new hedge trimmer. Pay close attention to the Rules For Safe Operation, Warnings and Cautions. If you use your hedge trimmer properly and only for what it is intended, you will enjoy years of safe, reliable service.
ELECTRICAL CONNECTION
Your hedge trimmer has a precision built electric motor. It should be connected to a power supply that is 120
volts, 60 Hz, AC only (normal household current). Do not operate this tool on direct current (DC). A
substantial voltage drop will cause a loss of power and the motor will overheat. If your hedge trimmer does not
operate when plugged into an outlet, double check the power supply,

parts are isolated from internal metal motor
components with protecting Insulation. Double
insulated tools do not need to be grounded.

RULES FOR SAFE OPERATION (Continued)
^ WARNING: Avoid dangerous
environment and guard against electric shock hazard. Don't use trimmer in rain, in damp or wet locations, or on wet hedges and shrubbery. Use only extension cords in good condition and marked "suitable for use with outdoor appliances" having electrical rating not less than rating of trimmer. Do not use damaged extension cords. Inspect cords periodically and replace if damaged. Do not abuse cord. Never carry trimmer by cord. Do not yank cord to disconnect from receptacles. Keep cord away from heat, oil, sharp edges, and moving blades.
^ WARNING: To reduce the risk of electric
shock, use only with an extension cord intended for outdoor use, such as SW-A, SOW-A, STW-A, STOW-A, SJW-A, SJOW-A, SJTW-A or SJTOW-A.
WHEN OPERATING YOUR TRIMMER -
keep extension cord behind trimmer. Never drape it over hedge being trimmed.

sure trimmer switch is off. Don't carry trimmer with finger on switch.
DISCONNECT (UNPLUG) TRIMMER
FROM POWER SUPPLY. Disconnect the
hedge trimmer from power supply when not in use, before servicing, when changing accessories such as blades, when cleaning, and the like.
MAINTAIN TRIMMER WITH CARE. Keep cutting edge sharp and clean for best performance and to reduce the risk of injury.
Follow instructions for lubricating and changing accessories. Inspect hedge trimmer cord periodically, and if damaged,
have it repaired by an authorized service facility. Inspect extension cord periodically and replace if damaged. Keep handles dry, clean, and free from oil and grease.
STORE TRIMMER INDOORS. When not in use, store trimmer indoors in a dry place where not accessible to children.
CHECK DAMAGED PARTS. Before futher 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, bind ing 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 repairet or replaced by an authorized service center unless indicated elsewhere in this manual.
DO NOT ATTEMPT TO REPAIR TRIM MER. For service or repair return the trim

RULES FOR SAFE OPERATION (Continued)
EXTENSION CORDS. The use of any extension cord will cause some loss of power. To keep the loss to a minimum and to prevent tool overheating, be sure to use an extension cord heavy enough to carry the current your product will draw. For
lengths less than 100 feet, No. 16 A.W.G, extension cords should be used. Follow the recommended cord sizes on the following chart when using extension cords. If in doubt, use the next heavier gage. The
smaller the gage number the heavier the cord. For tools rated 6 amps or less;
Extension Cord Length Wire Size A.W.G.
25 Feet 18
50 Feet 16 100 Feet 16 150 Feet 14
To reduce the risk of disconnection of hedge trimmer from the extension cord during operation:
(1) Use the extension cord retainer as shown in Figure 5, or
(2) Make a knot as shown in Figure 6.
A WARNING: Check extension cords before
each use. If damaged, replace immediately.
Never use tool with a damaged cord since touching the damaged area could cause glectrical shock resulting in serious injury.
POLARIZED PLUGS. To reduce the risk of
electric shock, this appliance has a polar ized plug (one blade is wider than the other) and will require the use of a polarized extension cord. The appliance plug will fit
into a polarized extension cord only one
way. If the plug does not fit fully into the
extension cord, reverse the plug. If the plug still does not fit, obtain a correct polarized extension cord. A polarized extension cord will require the use of a polarized wall outlet. This plug will fit into the polarized wall outlet only one way. If the plug does
not fit fully into the wall outlet, reverse the plug. If the plug still does not fit, contact a qualified electrician to install the proper wall outlet. Do not change the equipment plug, extension cord receptacle, or extension cord plug in any way.
SAVE THESE INSTRUCTIONS. Refer to them frequently and use them to instruct others who may use this tool. If you loan someone this tool, loan them these instruc tions.
WARNING:
The operation of any hedge trimmer can result in foreign objects being thrown into your eyes, which can result in severe eye damage. Before beginning power tool operation,
always wear safety goggles or safety glasses with side shields and a full face shield when needed. We recommend Wide Vision Safety Mask for use over eyeglasses or standard safety glasses with side shields, available at Sears Retail Stores.

TRIMMING A HEDGE
See Figures 8 and 9.
Wear gioves when trimming thorny or prickly growth.
Fig. 8
USE TRIMMER PROPERLY. Hold the hedge trimmer
with both hands and with the cutter blade away from you BEFORE starting trimmer.
WARNING: Keep hands and fingers away from
moving parts. Any part of body coming in contact
with moving parts could result in serious injury.
Always keep cord behind your hedge trimmer when in use. Do not place it over the hedge where it may be cut by the blade.
When trimming new growth, use a wide, sweeping action so that the stems are fed directiy into the cutter blade. Older growth will have thicker stems and will be trimmed easiest by using a sawing movement. Do not try to cut stems that are larger than 3/8 in. thick or those obviously too large to feed into the cutter blade.
Use a non-powered hand saw or pruning saw to cut
the larger stems.
WARNING: To prevent possible serious injury
from accidental starting, disconnect your trimmer from power supply and carry by the front handle when not in use.
WARNING: Cord coming in contact with a
moving blade could result in damaged cord. Replace a damaged cord immediately. Never
