Installing Or Removing The Shear Blades - Makita DUH604S Manual De Instrucciones

Reverse button for debris removal
WARNING:
If the entangled branches or
debris cannot be removed by the reverse func-
tion, switch off the tool and remove the bat-
tery cartridge, and then remove the entangled
branches or debris using tools such as pliers.
Failure to switch off the tool and remove the bat-
tery 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, press the
reverse button when the shear blades have stopped,
then pull the front switch trigger, and then pull the rear
switch trigger while pressing the lever. The power lamp
starts blinking, and the shear blades move in reverse
direction.
When entangled branches and debris are removed,
the tool returns to the regular movement and the power
lamp stops blinking and lights up.

NOTE: If the entangled branches or debris cannot be
removed, release the switch triggers, then press the
reverse button, and then pull the switch triggers until
they are removed.
NOTE: If you tap the reverse button while the shear
blades are still moving, the tool comes to stop and to
be ready for reverse movement.
