damaged should be properly repaired or

replaced by an authorized service center

unless otherwise indicated elsewhere in

this manual.

_,WARNING: When servicing double

insulated tools, USE ONLY IDENTICAL

REPLACEMENT PARTS. Replace or

repair damaged cords.

AWARNING: Toprevent electrical shock

hazard, use only with an extension cord

suitable for outdoor use. Always connect

extension cords to a fused line or one

_protected by a circuit breaker.

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.

• 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

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

PARTS. Repair or replace damaged

cords.

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. Ifthe

plug does not fit fully into the extension

cord, reverse the plug. If it still does not

fit, obtain a suitable extension cord. Ifthe

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.

_,WARNING: Some dust created when

using lawn and garden power tools

contains chemicals known to cause

cancer, birth defects and other

reproductive harm.

Some examples of these chemicals are:

• crystalline silica from sand, bricks and

other masonry dust

• arsenic and chromium from chemically

treated lumber (CCA)

• compounds in fertilizers

• compounds in insecticides, herbicides

and pesticides

Health risk from these chemical

exposures varies, depending on the

environment in which you are working and

how often you do this type of work. To

reduce your exposure to these chemicals,

follow product label instructions to apply

chemicals such as fertilizers, insecticides,

herbicides or pesticides. When using

these tools, wear safety equipment such

as gloves and dust masks which are

especially designed to filter out

microscopic particles.

BLOWER FUNCTION

(FIGURE 10)

The air flow created by the motor funnels

up through the guard to provide a built-in

blower. This feature can be used to blow

grass clippings off of sidewalks and other

hard surface areas.

CUTTING LINE / LINE FEEDING

Your trimmer uses .065 inch (1.65

mm) diameter, ROUND nylon line.

During use, the tips of the nylon lines

will become frayed and worn and the

special self feeding line hub will

automatically feed and trim a fresh

length of line. Cutting line will wear

faster and require more feeding if the

cutting or edging is done along

sidewalks or other abrasive surfaces

or heavier weeds are being cut. The
