● When changing the rotational speed with the shift
knob, confirm that the switch is off.
Changing the speed while the motor is rotating
will damage the gears.
● When setting the shift knob to "HIGH" (high
speed) and the position of the clutch dial is
bitween "16" and "22", it may happen that the
clutch does not engaged and that the motor is
locked. In such a case, please set the shift knob to
"LOW" (low speed).
● If the motor is locked, immediately turn the power
off. If the motor is locked for a while, the motor or
battery may be burnt.
● To extend the lifetime, the lithium-ion battery
equips with the protection function to stop the
output. Therefore, if the tool is overloaded, the
motor may stop. However, this is not the trouble
but the result of protection function. In this case,
release the switch of tool and eliminate the causes
of overloading.
