Functional Description - Makita DTM40 Instruction Manual

Tape or mask off open contacts and pack up the bat-
tery in such a manner that it cannot move around in
the packaging.
11. When disposing the battery cartridge, remove it
from the tool and dispose of it in a safe place.
Follow your local regulations relating to disposal
of battery.
12. Use the batteries only with the products speci-
fied by Makita. Installing the batteries to non-com-
pliant products may result in a fire, excessive heat,
explosion, or leak of electrolyte.
13. If the tool is not used for a long period of time,
the battery must be removed from the tool.
14. During and after use, the battery cartridge may
take on heat which can cause burns or low tem-
perature burns. Pay attention to the handling of
hot battery cartridges.
15. Do not touch the terminal of the tool immediately
after use as it may get hot enough to cause
burns.
16. Do not allow chips, dust, or soil stuck into the
terminals, holes, and grooves of the battery car-
tridge. It may cause heating, catching fire, burst and
malfunction of the tool or battery cartridge, resulting
in burns or personal injury.
17. Unless the tool supports the use near high-volt-
age electrical power lines, do not use the battery
cartridge near high-voltage electrical power
lines. It may result in a malfunction or breakdown of
the tool or battery cartridge.
18. Keep the battery away from children.
SAVE THESE INSTRUCTIONS.
CAUTION: Only use genuine Makita batteries.
Use of non-genuine Makita batteries, or batteries that
have been altered, may result in the battery bursting
causing fires, personal injury and damage. It will also
void the Makita warranty for the Makita tool and charger.
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 tempera-
ture at 10 °C - 40 °C (50 °F - 104 °F). Let a hot bat-
tery cartridge cool down before charging it.
4. When not using the battery cartridge, remove it
from the tool or the charger.
5. Charge the battery cartridge if you do not use it
for a long period (more than six months).

FUNCTIONAL DESCRIPTION

WARNING:
• Always be sure that the tool is switched off and
battery cartridge is removed before adjusting or
checking function on the tool. Failure to switch off
and remove the battery cartridge may result in serious
personal injury from accidental start-up.
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, slide the slide switch on the tool toward
the "O (OFF)" position and stop the application that
caused the tool to become overloaded. Then slide the
slide switch toward the "I (ON)" position again to
restart.
If the tool does not start, the battery is overheated. In
this situation, let the battery cool before sliding the slide
switch toward the "I (ON)" position 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.
Indicating the remaining battery capacity (Fig. 3)
Only for battery cartridges with the indicator
Press the check button on the battery cartridge to indi-
cate the remaining battery capacity. The indicator lamps
light up for few seconds.
