Technology), ADT indicator turns on and the tool runs
at optimum rotation speed and torque for the condi-
tion of grass being cut.
Reverse button for debris removal
WARNING:
Switch off the tool and remove
the battery cartridge before you remove entan-
gled weeds or debris which the reverse rotation
function can not remove. Failure to switch off and
remove the battery cartridge may result in serious
personal injury from accidental start-up.
This tool has a reverse button to change the direction of
rotation. It is only for removing weeds and debris entan-
gled in the tool.
To reverse the rotation, tap the reverse button and pull
the switch trigger while depressing the lock-off lever
when the cutting tool is stopped. The speed indicators
and ADT indicator start blinking, and the cutting tool
rotates in reverse direction when you pull the switch
trigger.

High 6,000 min
Medium 5,100 min
Low 3,500 min
To return to regular rotation, release the trigger and wait
until the cutting tool stops.

tool is still rotating, the tool comes to stop and to be
ready for reverse rotation.
