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

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 (Fig. 2)
The tool and battery are equipped with a protection sys-
tem. 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, release the switch trigger on the tool
and stop the application that caused the tool to become
overloaded. Then pull the switch trigger again to
restart.
If the tool does not start, the battery is overheated. In
this situation, let the battery cool before pulling the
switch trigger again.
• Low battery voltage:
The remaining battery capacity is too low and the tool
will not operate. In this situation, remove and recharge
the battery.
NOTE:
• Those temperature-sensitive protection and low-volt-
age protection is applied only when the tool is used
with a battery cartridge with a star mark.
Switch action (Fig. 3)
CAUTION:
• Before inserting the battery cartridge into the tool,
always check to see that the switch trigger actuates
properly and returns to the “OFF” position when
released.
To start the tool, simply pull the switch trigger. Tool speed
is increased by increasing pressure on the switch trigger.
Release the switch trigger to stop.
