Switch action
WARNING:
For your safety, this tool is
equipped with the lock-off switch which prevents
the tool from unintended starting. NEVER use
the tool if it runs when you simply pull the switch
trigger without releasing the lock-off switch.
Return the tool to our authorized service center
for proper repairs BEFORE further usage.
CAUTION:
Before installing the battery car-
tridge into the tool, always check to see that the
switch trigger actuates properly and returns 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 personal injury.
NOTICE:
Do not pull the switch trigger hard with-
out releasing the lock-off switch. This can cause
switch breakage.
NOTICE:
The lock-off switch cannot be released
while the arm is being pivoted beyond 90°.
To prevent the switch trigger from being accidentally
pulled, a lock-off switch is provided. Depress the switch
lever ( ) from the A side to unlock the switch trigger,
and ( ) from the B side to lock in.

NOTE: When the tool is overheated, the light flashes
for one minute. In this case, cool down the tool before
operating again.
NOTE: Use a dry cloth to wipe the dirt off the lens of
the lamp. Be careful not to scratch the lens of lamp, or
it may lower the illumination.
Speed adjusting dial
The belt speed can be adjusted between 600 m and
1,700 m per minute (1,970 - 5,600 ft/min) by turning the
speed adjusting dial to a given number setting from 1
to 5.
Higher speed is obtained when the dial is turned in the
direction of number 5; lower speed is obtained when it
is turned in the direction of number 1. Select the proper
speed for the workpiece to be sanded.
CAUTION:
The speed adjusting dial can only
be turned between the numbers indicated on the
dial. Do not apply an excessive force to turn the
dial outside that range, or the speed adjustment
may not function.
