OPERATING THE GRASS TRIMMER
See Figure 11.
Hold the grass trimmer with your right hand on the rear handle
and your left hand on the front handle. Keep a firm grip with
both hands while in operation. Grass trimmer should be held
at a comfortable position with the rear handle about hip height.
Always operate grass trimmer with switch trigger completely
depressed. If debris becomes wrapped around the string
head, RELEASE THE SWITCH TRIGGER, remove the battery
pack, and remove the debris.
WARNING:
Always hold the grass trimmer away from the body
keeping clearance between the body and the grass
trimmer. Any contact with the cutting head while
operating can result in serious personal injury.
WARNING:
Extreme care must be taken when using a blade
attachment to ensure safe operation. Read the safety
information for safe operation when using a blade
attachment and refer to the safety rules and instructions
in your attachment manual. Improper operation could
result in serious injury.
CUTTING TIPS
See Figure 12.
 Keep the trimmer tilted toward the area being cut; this is
the best cutting area.
 The grass trimmer cuts when passing the unit from right
to left. This will avoid throwing debris at the operator.
Avoid cutting in the dangerous area shown.
 Use the tip of the line to do the cutting; do not force string
head into uncut grass.
 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, siding,
and fence posts can easily be damaged by the line.
OPERATION
ADVANCING THE CUTTING LINE ON THE
BUMP FEED TRIMMER HEAD
Line advance is controlled by tapping the string head on
grass while running motor at full speed.
 Depress the switch trigger completely.
 Tap the bump knob on ground to advance line. The line
advances each time the knob is tapped. Do not hold the
knob on the ground.
NOTE: The line trimming cut-off blade on the grass
deflector will cut the line to the correct length.
NOTE: If the line is worn too short you may not be able to
advance the line by tapping it on the ground. If so, remove
the battery pack and manually advance the line.
To advance the cutting line manually:
 Remove the battery pack.
 Push the bump knob in while pulling on line(s) to manually
advance the line.
ADJUSTING THE LINE CUT-OFF BLADE
See Figures 13 - 14.
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 currently set at the 17 in. cutting swath. To
adjust to a cutting swath of 15 in.:
 Remove the battery pack.
 Loosen the blade screw then rotate the line cut-off
blade 180°.
 Tighten the blade screw.
WARNING:
The line cut-off blade on the grass deflector is sharp. Use
gloves while working with the blade. Direct contact with
the blade can result in serious personal injury.
