Optional Accessory - Makita DUH501 Manuel D'instructions

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 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 and pull the switch trigger 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.
