jacketed extension cords approved for outdoor use,  
such as cords of type SW-A, SOW-A, STW-A, STOW-  
A, SJOW-A, SJTW-W, or SJTOW-A. Since this tool is  
double insulated, you may use a 2-wire extension cord  
(an extension cord without a ground). However, you  
may also use a 3-wire extension cord (an extension  
cord with a ground) that has a NEMA-type connector  
(parallelblade,Uground).Extensioncordsareavailable

ized wall outlet. This product’s plug fits into a polarized  
wall outlet in 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 product plug, the

EXTENSION CORD RETAINER  
n An extension cord retainer is located on the bottom  
of the trimmer. This provides strain relief for the cord,  
preventing unwanted disconnects.  
Note: To reduce the disconnection of the power cord  
from the extension cord during operation, use the  
extension cord retainer described below.  
METHOD OF SECURING EXTENSIONCORD  
n
Use the extension cord retainer when you connect  
the extension cord to the power cord to prevent dis-  
connection. Use only an outdoor approved extension  
cord as indicated by the letters “W-A” on the cord’s  
jacket.  
n
Loop the extension cord through the extension cord  
retainer slot located on the bottom end of the trim-  
mer. See Figure 5.

earlier in this manual.  
Fig.7  
Hold the trimmer with your right hand on the trigger  
handle and your left hand on the front handle.  
NOTE: Keep a firm grip with both hands during op-  
eration.  
n
Place the trimmer on the right side of your body with  
the engine behind and away from your body.  
n
n
Press the trigger to start the trimmer.  
Trim grass and weeds in a right-to-left motion with the  
line parallel to the ground.  
CUTTING TIPS  
n
Inspect and clear the area to be trimmed for any rocks,  
broken glass, or wire that could be thrown or become  
entangled in the cutting line.  
n
n
n
Trim only when grass or weeds are dry.  
Keep the cutting line parallel to the ground.  
Cut grass or weeds over eight inches tall from the top  
to the bottom in small amounts. This will prevent grass  
becomingwrappedaroundthetrimmerheadassembly,  
whichmayresultindamageduetooverheating.Ifgrass  
becomeswrappedaroundthetrimmerheadassembly,  
stop the trimmer, unplug it, and remove the grass.  
n
Move the trimmer slowly in and out of the area you  
are cutting, keeping the trimmer at the desired cutting  
height.  
Fig. 8  
n
n
Use the tip of the line to do the cutting. Do not force  
the trimmer head assembly into uncut grass.  
Feed out some line after each use to prevent the line  
from retracting into the cutting head.  
Page 11  
 
OPERATION  
n
The tip of the cutting line will wear during use; this  
reduces the cutting swath. If the line is not advanced  
occasionally, it will wear down to the eyelet. When the  
trimmer stops, the line tends to relax and may retract  
into the trimmer head assembly. Should this occur,  
unplug the trimmer, remove the spool, refeed the line  
through the eyelets, and reassemble the spool.  
n
n
Avoid hitting objects with the line, such as chain-link  
fences or concrete, as this causes rapid wear.  
RETAINING  
CAP  
Never drag the trimmer head assembly on the ground  
while trimming.  
ADVANCING THE CUTTING LINE AUTO-  
MATICALLY  
See Figure 9.  
The trimmer includes the EZ Line™ Tap Advance Sys-  
tem.

n
Press the trigger.  
Tap the retaining cap lightly on the ground while the  
motor is running. Do not hold the retaining cap on the  
ground.  
LINE  
NOTE: The line cutting blade on the grass deflector  
will cut the line to the proper length.  
RETAINING  
CAP  
NOTE: To help prevent line tangle, tap only once to  
lengthen the line. If additional line is required, wait a  
few seconds before retapping the retaining cap. Keep  
the line length at or near full cutting diameter.

THE  
CUTTING  
LINE  
MANUALLY  
See Figure 10.  
Fig. 10  
If the cutting line wears to less than the recommended  
length, you may not be able to lengthen it by tapping the  
retaining cap.  
Follow these steps to advance the cutting line manually.  
n

Unplug the trimmer.  
Pull sharply on the line while pushing down on the

OPERATION  
CUT OFF BLADE  
This trimmer is equipped with a cut-off blade on the grass  
deflector. For best cutting, advance string until it is trimmed  
to length by the cut-off blade. Advance string whenever  
you hear the engine running faster than normal. This will  
maintain best performance and keep string long enough  
to advance properly.  
DIRECTION OF ROTA-  
TION  
CUTTING TIPS  
See Figure 11.  
n
Keep the trimmer tilted toward the area being cut; this  
is the best cutting area.  
n
n
Do not cut in dangerous cutting area.  
Use the tip of string to do the cutting; do not force  
string head into uncut grass.  
n
n
Wire and picket fences cause extra string wear, even  
breakage. Stone and brick walls, curbs, and wood  
may wear string rapidly.  
DANGEROUS CUTTING  
AREA  
BEST CUTTING  
AREA  
Avoid trees and shrubs. Tree bark, wood moldings,  
siding, and fence posts can easily be damaged by  
the string.
