Power switch action
WARNING:
For your safety, this tool is
equipped with lever which prevents the tool from
unintended starting. NEVER use the tool if it runs
when you simply pull the switch triggers without
pressing the lever. Return the tool to our autho-
rized service center for proper repairs BEFORE
further usage.
WARNING:
NEVER tape down or defeat pur-
pose and function of the lever.
WARNING:
Before installing the battery
cartridge on the tool, always check to see that
the switch triggers and lever actuate properly
and return to the "OFF" position when released.
Operating a tool with a switch that does not actuate
properly can lead to loss of control and serious per-
sonal injury.
CAUTION:
Never put your finger on the
switch triggers when carrying. The tool may start
unintentionally and cause injury.
NOTICE:
Do not pull the switch trigger hard
without pressing the lever. This can cause switch
breakage.
Press the main power button to turn on the tool. The
power lamp lights up when the tool is turned on. To turn
off the tool, press and hold the main power button. The
power lamp goes off when the tool is turned off.

NOTE: The tool is automatically turned off if the tool is
not operated for a certain period.
To prevent the switch trigger from being accidentally
pulled, the lever is provided. To start the tool, pull the
front switch trigger, and then pull the rear switch trigger
while pressing the lever. When you release either of the
switch triggers, the tool stops.

Reverse button for debris removal
WARNING:
debris cannot be removed by the reverse func-
tion, 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 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.
ASSEMBLY
CAUTION:
Always be sure that the tool is
