• STAY ALERT. Watch what you are doing. Use common sense. Do
not operate appliance when you are tired.

• CHECK DAMAGED PARTS. Before further use of the appliance, 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

accessory or attachment not recommended for use with this
appliance could be hazardous. Note: Refer to the accessory section

of this manual for further details.
EXTENSION CORDS. Make sure your extension cord is in good

condition. When using an extension cord, be sure to use one 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 table below shows the correct size to
use depending on cord length and nameplate ampere rating. If in
doubt, use the next heavier gauge. The smaller the gauge number,

the heavier the cord. To reduce the risk of disconnection of the
appliance from the extension cord during operation, use the

extension cord retainer described in this manual.

adjustments not specified in this manual should be performed by

organizations, always using identical replacement parts.

z_iMPORTANT WARNINGS FOR STRING

TRIMMERS

1. Use the proper size and type of cutting line. Do not use metal
wire, rope or the like. Do not use cutting line heavier than that

recommended by the manufacturer. See the accessory section of
this manual for more detailed information about the proper

cutting line to use.

2. Keep the cutting line trimmed to the proper length (done
automatically by the appliance). Make sure that the guard is

firmly in place, in working order and positioned between yourself
and the cutting line.

3. Wear long pants and substantial footwear to protect yourself from
injury caused by flying debris. This is especially important when

edging with the appliance.

/_ SAFETY WARNINGS AND INSTRUCTIONS:

POLARIZED PLUGS

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 asuitable 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.

OPERATING INSTRUCTIONS FOR CATALOG # ST4500
BUMP FEED TRIMMER

LiNE FEED

Your trimmer uses .065 in. (1.65 mm) diameter, ROUND nylon line
to cut grass and weeds quickly and easily. 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. As you use the trimmer, the string will get shorter due to
wear. Gently bump the unit on the ground and the line will feed.

Z_CAUTION: ALWAYS USE EYE PROTECTION.

ZkCAUTION: Inspect area to be trimmed and remove any wire,

cord, or string-like objects which could become entangled in the
rotating line or spool. Be particularly careful to avoid any wire which
might be bent outwardly into the path of the tool, such as barbs at

the base of a chain link fence.

RELOADING LiNE ST4500

side at a time.

3. Remove any broken cutting line,

wrap the remaining line tight and

reinsert spool into hub as

follows.

a.Wind the line tight enough so

that it is all below the edges of
the flanges on the spool. If it
extends past the flanges, it

won't fit into the hub.

b.Place the loose end of the

cutting line through the gap in
the spool flange as shown in
figure 12. (Either gap will do

but try to leave yourself about

3 or 4 inches of line to work
with.)

c. Holding the line in the gap,

insert the end through the
eyelet in the hub and slip the
spool into the hub, as shown
in figure 13.
Make sure the spring is still in
place in the hub. Ifthe spool
does not slip into the hub
easily, press gently and pull
straight out on the cutting line
that protrudes through the
eyelet.

hub, align the release tabs on

the shroud with the slots in the
hub as shown infigure 14 and

press the shroud into place. Be
sure that both release tabs

snap into place.
