OPERATION


Wire and picket fences cause extra line wear, even
breakage. Stone and brick walls, curbs, and wood may
wear line rapidly.


Avoid trees and shrubs. Tree bark, wood moldings, sid -
ing, and fence posts can easily be damaged by the line.
ADVANCING LINE
NOTE: The trimmer is equipped with an auto-feed head.
Bumping the head to try to advance the line will damage
the trimmer and void the warranty.


With the trimmer running, release the switch trigger.


Wait two seconds, and press the switch trigger.
NOTE:
The line will extend approximately 1/4 in. with
each stop and start of the switch trigger until the line
reaches the length of the grass deflector cut-off blade.


Resume trimming.
ADVANCING THE LINE MANUALLY
See Figure 12.
  Remove the battery pack or disconnect from power
supply.


Push the black button located on the string head while
pulling on line to manually advance the line.
LINE CUT-OFF BLADE
See Figure 13.
This trimmer is equipped with a line cut-off blade on the
grass deflector. For best cutting, advance line until it is
trimmed to length by the line cut-off blade. Advance line
whenever you hear the motor running faster than normal,
or when trimming efficiency diminishes. This will maintain
best performance and keep line long enough to advance
properly.
This trimmer is set at the 10 in. cutting swath. To adjust to
a cutting swath of 12 in.:

 Remove the battery pack or disconnect from power
supply.


Loosen the blade screw then rotate the blade 180°.


Tighten the blade screw.
EDGING

Rotate the rear handle when using the edger guide for
edging sidewalks and walkways.
  Remove the battery pack or disconnect from power
supply.


Pull up edging boom coupler and turn handle end coun -
terclockwise.


Release edging boom coupler when handle has been
rotated 180° and locks into place.
Always hold the string trimmer away from the body keeping
clearance between the body and the string trimmer. Any
contact with the string trimmer cutting head while operating
can result in serious personal injury.
