KEEP ALL BY-STANDERS AWAY – At  
a safe distance from work area,  
tools in gaseous or explosive  
atmospheres. Motors in these tools  
normally spark, and the sparks might  
ignite fumes.  
especially children.  
IMPORTANT WARNING – When being  
used as an Edger, stones, pieces of  
metal and other objects can be thrown  
out at high speed by the line. The tool  
and guard are designed to reduce the  
danger. However, the following special  
precautions should be taken:  
STORE IDLE TOOLS INDOORS –  
When not in use, tools should be stored  
indoors in a dry, locked-up place out of  
reach of children.  
GROUND FAULT CIRCUIT  
INTERRUPTER (GFCI) protection  
should be provided on the circuits or  
outlets to be used for the gardening  
appliance. Receptacles are available  
having built in GFCI protection and may  
be used for this measure of protection.  
MAKE SURE that other persons and  
pets are at least 100 feet away.  
TO REDUCE THE RISK of rebound  
(ricochet) injury, work going away from  
any nearby solid object such as wall,  
steps, large stone, tree, etc. Use great  
care when working close to solid objects  
and where necessary, do edging or  
trimming by hand.  
SECURE EXTENSION CORD using the  
cord retainer shown in Figures 4 and 5.  
STAY ALERT – Watch what you are  
doing. Use common sense. Do not  
operate tool when you are tired.  
AVOID ACCIDENTALLY STARTING –  
Don’t carry plugged-in tool with finger on  
trigger.  
MAINTAIN APPLIANCES WITH CARE  
– Follow instructions for lubricating and  
changing accessories. Inspect extension  
cords periodically and replace if  
damaged. Keep handles dry, clean and  
free from oil and grease.  
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  
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 a qualified service facility  
unless otherwise indicated elsewhere in  
this manual.  
DO NOT FORCE THE TOOL – At a rate  
faster than the rate at which it is able to  
cut effectively.  
USE THE RIGHT TOOL – Do not use  
this tool for any job except that for  
which it is intended.  
DON’T OVERREACH – Keep proper  
footing and balance at all times.  
DON’T ABUSE CORD – Don’t yank  
cord from power supply. Keep cord from  
heat, oil, and sharp edges.  
DAMAGE TO UNIT – If you strike or  
become entangled with a foreign object,  
stop tool immediately, unplug, check for  
damage and have any damage repaired  
before further operation is attempted.  
Do not operate with a broken hub or  
spool.  
WARNING: When servicing double  
insulated tools, USE ONLY IDENTICAL  
REPLACEMENT PARTS. Replace or  
repair damaged cords.  
DAMAGE TO CORD – Keep power  
cord away from rotating line. If you  
damage the cord, unplug it from the  
power supply before moving the tool or  
examining the damage. A damaged cord  
must be replaced before further use.  
WARNING: To prevent 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.  
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  
DISCONNECT TOOL – When not in  
use, when replacing line, or prior to  
cleaning.  
AVOID DANGEROUS  
ENVIRONMENTAL CONDITIONS – Do  
not use electric tools in damp or wet  
locations. Follow all instructions in this  
Instruction Manual for proper operation  
of your tool. Don’t use the tool in the rain.

WARNING:  
Outdoor use extension cords:  
To reduce the risk of electric shock, use  
only with an extension cord intended for  
outdoor use, such as an extension cord of  
type SW-A, SOW-A, STW-A, STOW-A,  
SJW-A, SJOW-A, SJTW-A, or SJTOW-A.  
IMPORTANT WARNINGS FOR STRING TRIMMERS  
• The guard must be installed before  
trimming or edging - if not, the motor  
will overheat.  
• When replacing the line, use only .065”  
diameter ROUND line - otherwise the  
unit will not function properly.  
• Do not bump the feed head against the  
ground - it will disrupt the feed mechanism.  
• Angle tool slightly (5˚ to 10˚) when  
trimming.  
• Always use the cord retainer.  
• 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  
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.  
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 PARTS.

6. Snap the hub cover and spring back on  
and turn the tool on. In a few seconds  
or less you’ll hear the nylon line being  
cut automatically to the proper length.

CUTTING LINE  
Your trimmer uses only .065” (1.65 mm)  
diameter, ROUND nylon line to cut grass  
and weeds quickly and easily. During  
use, the tip of the nylon line 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 advanced automatic line feeding  
mechanism senses when more cutting  
line is needed and feeds and trims the  
correct length of line whenever its  
required. DO NOT BUMP unit on ground  
in attempt to feed line or for any other  
purposes.

cutting thick or stalky weeds, the line  
feeding hub may become clogged with  
sap or other material and the line will  
become jammed as a result. To clear the  
jam, follow the steps listed below.  
1. Unplug the trimmer.

4. If you are rewinding the spool with new  
line, see “Rewinding Spool”. If you are  
replacing the spool, use Craftsman  
replacement spool number 85820,  
available at Sears.

while placing the spool down into the  
hub, as shown in Figure 12.  
6. Press the spool down GENTLY and  
rotate it until you feel it drop into place.  
(When in place, the spool will turn a  
few degrees left and right freely). Take  
care to keep the line from becoming  
trapped under the spool.  
7. Snap the hub cover back on, (figure 10)  
and turn the tool on. In a few seconds  
or less you’ll hear the nylon line being  
cut automatically to the proper length.  
REWINDING SPOOL  
Use .065” diameter ROUND line only. Do  
not use heavier gauge line; it will  
overload motor and cause overheating.  
1. Insert line end about 1/4” into the  
spool hole.  
2. Snugly and evenly wind the line onto  
the spool in the direction of the arrow  
on the spool until the line builds up to  
the notches in the spool rim  
(Figure 13). Do not overfill spool. The  
spool holds about 30 feet of line.  
3. Proceed to step 5 of “Spool or Line  
Replacement”
