(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 a damaged battery.
SAVE THESE INSTRUCTIONS.
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.
4. Charge the battery cartridge once in every six
months if you do not use it for a long period of
time.

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)
CAUTION:
• Always switch off the tool before installing or removing
of the battery cartridge.
• Hold the tool and the battery cartridge firmly when
installing or removing battery cartridge. Failure to
hold the tool and the battery cartridge firmly may cause
them to slip off your hands and result in damage to the
tool and battery cartridge and a personal injury.
To remove the battery cartridge, slide it from the tool
while sliding the button on the front of the cartridge.
To install the battery cartridge, align the tongue on the
battery cartridge with the groove in the housing and slip it
into place. Insert it all the way until it locks in place with a
little click. If you can see the red indicator on the upper
side of the button, it is not locked completely.
CAUTION:
• Always install the battery cartridge fully until the red
indicator cannot be seen. If not, it may accidentally fall
out of the tool, causing injury to you or someone
around you.
• Do not install the battery cartridge forcibly. If the car-
tridge does not slide in easily, it is not being inserted
correctly.
Battery protection system (Lithium-ion battery
with star marking) (Fig. 2)
Lithium-ion batteries with a star marking are equipped
with a protection system. This system automatically cuts
off power to the tool to extend battery life.

The tool will automatically stop during operation if the
tool and/or battery are placed under one of the following
conditions:
• Overloaded:
The tool is operated in a manner that causes it to draw
an abnormally high current.
In this situation, stop the application that caused the
tool to become overloaded. Then press the start/speed
adjusting button again to restart.
If the tool does not start, the battery is overheated. In
this situation, let the battery cool before pressing the
start/speed adjusting button.
• Low battery voltage:
The remaining battery capacity is too low and the tool
will not operate. In this situation, remove and recharge
the battery.
Switch action and speed adjusting button (Fig. 3)
To start the tool, press the start/speed adjusting button.
The tool starts with high speed mode. Each time you
press the start/speed adjusting button, the speed mode
changes in an order of hi speed, middle speed, and low
speed.
To stop the tool, press the stop button.
Refer to the table for the relationship between the speed
mode and the kind of work.

downwards.
Emptying dust bag (Fig. 6 & 7)
When the dust bag is about half full, switch off the tool,
and remove the dust bag from the tool. Then remove the
dust nozzle from the dust bag after unlocking the dust
nozzle by turning it slightly counterclockwise. Empty the
dust bag by tapping it lightly.
After emptying the dust bag, install the dust nozzle on the
