Reverse button for debris removal
WARNING:
If the entangled branches or debris can-
not be removed by the reverse function, switch off the tool
and remove the battery cartridge, and then remove the entan-
gled branches or debris using tools such as pliers. Failure to
switch off the tool and remove the battery cartridge may result in
serious personal injury from accidental start-up. Removing the
entangled branches or debris by hand may cause an injury, since
the shear blades may move in reaction to removing them.
This tool has a reverse button to change the direction
of shear blades movement. It is only for removing
branches and debris entangled in the tool.
To reverse the shear blades movement, tap the reverse
button when the shear blades have stopped, then press
the switch lever and pull the switch trigger while press-
ing the lock-off lever. The speed indicators start blink-
ing, and the shear blades move in reverse direction.
To return to regular movement, release the trigger and
wait until the shear blades stop.
