NOTE: Depending on the conditions of use and the
ambient temperature, the indication may differ slightly
from the actual capacity.
NOTE: The first (far left) indicator lamp will blink when
the battery protection system works.
Tool / battery protection system
The tool is equipped with a tool/battery protection sys-
tem. This system automatically cuts off power to the
motor to extend tool and battery life. The tool will auto-
matically stop during operation if the tool or battery is
placed under one of the following conditions:
Overload protection
When the tool or battery is operated in a manner that
causes it to draw an abnormally high current, the tool
automatically stops without any indication. In this sit-
uation, turn the tool off and stop the application that
caused the tool to become overloaded. Then turn the
tool on to restart.
Overheat protection
When the tool or battery is overheated, the tool stops
automatically. In this case, let the tool and battery cool
before turning the tool on again.
Overdischarge protection
When the battery capacity is not enough, the tool stops
automatically. In this case, remove the battery from the
tool and charge the battery.
Switch action
CAUTION:
Avoid turning the tool on while it
is placed on the workpiece or on your workbench.
It may cause personal injury or damage.
Turning the tool on and off
Press the power/speed select button on the top of the
main handle to start the tool. The tool starts to run at its
highest orbital speed.
Press the stop button to pause or cease operation.

Changing the tool speed
The orbital speed can be changed in three modes, that
is, high, medium and low depending on the application
and workload.
Press the power/speed select button to switch speed
mode.

NOTICE:
If the tool is operated continuously
at low speeds for a long time, the motor will get
overloaded, resulting in tool malfunction.
NOTICE:
Select an appropriate speed range for
your sanding operations to avoid overheating
and melting the workpiece. Sanding at high orbital
speed may heat workpiece and melt it at the point of
contact.
Electronic function
The tool is equipped with the electronic function for
easy operation.
Constant speed control
This function serves a constant orbital speed to obtain
fine finish.
ASSEMBLY
CAUTION:
Always be sure that the tool is
switched off and the battery cartridge is removed
before carrying out any work on the tool.
Installing and removing abrasive
paper
CAUTION:
Always make sure that a sheet of
abrasive paper is installed securely before use.
The paper may otherwise be loosened, removed
easily and subject to slippage, resulting in uneven
sanding operation.
Using hook-and-loop abrasive paper
CAUTION:
Make sure to install a hook-and-
loop pad correctly and securely. A loose attach-
ment will run out of balance and cause an excessive
vibration resulting in loss of control.
CAUTION:
Be sure that a hook-and-loop pad
and abrasive paper are aligned and securely
attached.
CAUTION:
Only use hook-and-loop abrasive
papers. Never use pressure-sensitive abrasive
papers.
1. Remove all dirt and foreign matter from the hook-
and-loop pad.
2.
Attach a sheet of the abrasive paper to the pad,
aligning the dust-suction holes in the paper with those
in the pad.
