(2) Avoid storing battery cartridge in a container
with other metal objects such as nails, coins,
etc.
(3) Do not expose battery cartridge to water or
rain.
A battery short can cause a large current flow,
overheating, possible burns and even a
breakdown.
6. Do not store the tool and battery cartridge in
locations where the temperature may reach or
exceed 50°C (122°F).
7. Do not incinerate the battery cartridge even if it is
severely damaged or is completely worn out. The
battery cartridge can explode in a fire.
8. Be careful not to drop or strike battery.

Tips for maintaining maximum battery life
1. Charge the battery cartridge before completely
discharged.
Always stop tool operation and charge the battery
cartridge when you notice less tool power.
2. Never recharge a fully charged battery cartridge.
Overcharging shortens the battery service life.
3. Charge the battery cartridge with room
temperature at 10°C - 40°C (50°F - 104°F). Let a hot
battery cartridge cool down before charging it.

FUNCTIONAL DESCRIPTION
CAUTION:
• Always be sure that the tool is switched off and the
battery cartridge is removed before adjusting or
checking function on the tool.
Installing or removing battery cartridge
(Fig. 1)
• Always switch off the tool before insertion or removal of
the battery cartridge.
• To remove the battery cartridge, withdraw it from the
tool while sliding the button on the front of the cartridge.
• To insert the battery cartridge, align the tongue on the
battery cartridge with the groove in the housing and slip
it into place. Always insert it all the way until it locks in
place with a little click. If you can see the red part on
the upper side of the button, it is not locked completely.
Insert it fully until the red part cannot be seen. If not, it
may accidentally fall out of the tool, causing injury to
you or someone around you.
• Do not use force when inserting the battery cartridge. If
the cartridge does not slide in easily, it is not being
inserted correctly.
Shaft lock (Fig. 2)
CAUTION:
• Never actuate the shaft lock when the spindle is
moving. The tool may be damaged.
Press the shaft lock to prevent spindle rotation when
installing or removing accessories.
Switch action (Fig. 3)
CAUTION:
• Before inserting the battery cartridge into the tool,
always check to see that the slide switch actuates
properly and returns to the “OFF” position when the
rear of the slide switch is depressed.
To start the tool, slide the slide switch toward the “I (ON)”
position. For continuous operation, press the front of the
slide switch to lock it.
To stop the tool, press the rear of the slide switch, then
slide it toward the “O (OFF)” position.
Indication lamp with multi function
(Fig. 4)
Indication lamps are located in two positions.
When the battery cartridge is inserted on the tool with the
slide switch positioned in the “O (OFF)” position, the
indication lamp flickers quickly for approximately one
second. If it does not flicker so, the battery cartridge or
indication
lamp has broken.
- Overload protection
- When the tool is overloaded, the indication lamp lights
up. When the load on the tool is reduced, the lamp
goes out.
- If the tool continues to be overloaded and the
indication lamp continues to light up for approximately
two seconds, the tool stops. This prevents the motor
and its related parts from being damaged.
- In this case, to start the tool again, move the slide
switch to the “O (OFF)” position once and then to the “I
(ON)” position.
- Battery cartridge replacing signal
- When the remaining battery capacity gets small, the
indicator lamp lights up during operation earlier than
enough capacity battery use.
- Accidental re-start preventive function
- Even if the battery cartridge is inserted on the tool with
the slide switch in the “I (ON)” position, the tool does
not start. At this time, the lamp flickers slowly and this
shows that the accidental re-start preventive function
is at work.
- To start the tool, first slide the slide switch toward the
“O (OFF)” position and then slide it toward the “I (ON)”
position.
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.
