Switch action
WARNING: For your safety, this tool is
equipped with lock-off lever which prevents
the tool from unintended starting. NEVER
use the tool if it runs when you simply
pull the switch trigger without pressing
the lock-off lever. Return the tool to our
authorized service center for proper repairs
BEFORE further usage.
WARNING: NEVER tape down or defeat
purpose and function of lock-off lever.
CAUTION: Before installing the battery
cartridge into the tool, always check to see
that the switch trigger actuates properly
and returns to the "OFF" position when
released.
NOTICE: Do not pull the switch trigger hard
without pressing the lock-off lever. This can
cause switch breakage.
NOTE: When you keep pulling the switch trig-
ger while the tool is under almost no load, the
rotation speed of the tool decreases and the
main power lamp blinks in green. In this case,
release the switch trigger, and then pull the
switch trigger again.
To prevent the switch trigger from being acci-
dentally pulled, a lock-off lever is provided. To
start the tool, depress the lock-off lever and pull
the switch trigger. The tool speed increases
by increasing pressure on the switch trigger.
Release the switch trigger to stop.
