Electronic Function - Makita GHU04 Instruction Manual

Reverse button for debris removal
WARNING:
If the entangled branches or debris
cannot be removed by the reverse function, switch off
the tool and remove the battery cartridge, and then
remove the entangled 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, 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 speed indicators start blink-
ing, and the shear blades move in reverse direction.
When entangled branches and debris are removed,
the tool returns to the regular movement and the speed
indicators stop blinking and light up.

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.

Electronic function

easy operation.
• Constant speed control

ing the switch trigger, the tool does not start. To
start the tool, first release the switch trigger, and
then pull the switch trigger.
