5. Do not short the battery cartridge:
(1) Do not touch the terminals with any conduc-
tive material.
(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 break-
down.
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.
9. Do not use damaged battery.

Tips for maintaining maximum battery life
1. Charge the battery cartridge before completely
discharged.
Always stop tool operation and charge the bat-
tery 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 tempera-
ture at 10°C - 40°C (50°F - 104°F). Let a hot bat-
tery cartridge cool down before charging it.
FUNCTIONAL DESCRIPTION
CAUTION:
• Always be sure that the tool is switched off and the bat-
tery 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.
Switch action (Fig. 2)
CAUTION:
• Before inserting the battery cartridge into the tool,
always check to see that the slide switch actuates prop-
erly and returns to the “OFF” position when the rear of
the slide switch is depressed.
• Switch can be locked in “ON” position for ease of oper-
ator comfort during extended use. Apply caution when
locking tool in “ON” position and maintain firm grasp on
tool.
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. 3)
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 indi-
cation lamp flickers quickly for approximately one sec-
ond. 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 indica-
tion 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 bat-
tery cartridge is removed before carrying out any work
on the tool.
Installing or removing wheel point (Fig. 4 & 5)
Loosen the collet nut and insert the wheel point into the
collet nut. Use one wrench to hold the spindle and the
other one to tighten the collet nut securely.
The wheel point should not be mounted more than 8 mm
from the collet nut. Exceeding this distance could cause
vibration or a broken shaft.
To remove the wheel point, follow the installation proce-
dure in reverse.
CAUTION:
• Use the correct size collet cone for the wheel point
which you intend to use.
