CAUTION:
• Before inserting the battery pack
into the tool, always make sure that
the power switch operates properly
and returns to the "OFF" position
when the rear of the power switch

To stop the tool, press the rear of the
power switch, then slide it toward the

When operating the tool by pulling the
trigger, there may be a momentary lag
before rotation starts. This does not
signal a malfunction.
• This lag occurs as the tool's circuitry
starts up when the trigger is pulled
for the first time after installing a new
battery pack or after the tool has not
been used for at least 1 minute (or at
least 5 minutes when the LED is on).
Rotation will start without any lag
during second and subsequent op-
erations.

• It should never be necessary to
force the tool. The weight of the
tool applies adequate pressure.
Forcing and excessive pressure
could cause dangerous grinding
disc breakage.
• ALWAYS replace grinding disc if
tool is dropped while grinding.
• NEVER bang or hit grinding disc.
