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.
4. Charge the battery cartridge if you do not use it for
a long period (more than six months).
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. 7)
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
cartridge does not slide in easily, it is not being inserted
correctly.
NOTE:
• The tool does not work with only one battery cartridge.
• When the battery cartridge is not removed easily, push
it from the opposite side of the button and slide it.
Tool/battery protection system
The tool is equipped with a tool/battery protection system.
This system automatically cuts off power to the motor to
extend tool and battery life.
The tool will automatically stop during operation if the tool
or battery are placed under one of the following
conditions. In some conditions, the indicators light up.
(Fig. 8)
Overload protection
When the tool is operated in a manner that causes it to
draw an abnormally high current, the tool automatically
stops without any indications. In this situation, turn the tool
off and stop the application that caused the tool to
become overloaded. Then turn the tool on to restart.
Overheat protection for tool
When the tool is overheated, the tool stops automatically
and the overheat indicator lights up about 60 seconds. In
this situation, let the tool cool before turning the tool on
again.
Overheat protection for battery
When the battery is overheated, the tool stops
automatically without any indications. The tool does not
start even if pulling the switch trigger. In this situation, let
the battery cool before turning the tool on again.
NOTE:
The battery overheat protection works only with a battery
cartridge with a star marking. (Fig. 9)
Overdischarge protection
When the remaining battery capacity gets low, the battery
indicator blinks on the applicable battery side. By further
use, the tool stops and the battery indicator lights up
about 10 seconds. In this situation, charge the battery
cartridge.
Indicating the remaining battery capacity
Only for battery cartridges with the indicator (Fig. 10)
Press the check button on the battery cartridge to indicate
the remaining battery capacity. The indicator lamps light
up for a few seconds.

NOTE:
• Depending on the conditions of use and the ambient
temperature, the indication may differ slightly from the
actual capacity.
Adjusting depth of cut (Fig. 11)
CAUTION:
• After adjusting the depth of cut, always tighten the lever
securely.
Loosen the lever on the depth guide and move the base
up or down. At the desired depth of cut, secure the base
by tightening the lever.
For cleaner, safer cuts, set cut depth so that no more than
one blade tooth projects below workpiece. Using proper
cut depth helps to reduce potential for dangerous
KICKBACKS which can cause personal injury.
