Makita 4331D Betriebsanleitung Seite 7

CAUTION:
• The battery charger Model DC1411 is for charging Makita battery cartridge. Never use it for other purposes
or for other manufacturer's batteries.
• When you charge a new battery cartridge or a battery cartridge which has not been used for a long period of
time, it may not accept a full charge. This is a normal condition and does not indicate a problem. You can
recharge the battery cartridge fully after discharging it completely and recharging a couple of times.
• If you charge a battery cartridge from a just-operated tool or a battery cartridge which has been left in a
location exposed to direct sunlight or heat for a long time, the charging light may flash in red color. If this
occurs, wait for a while. Charging will begin after the battery cartridge cools. The battery cartridge will cool
faster if you remove the battery cartridge from the battery charger.
• If the charging light flashes alternately in green and red color, a problem exists and charging is not possible.
The terminals on the charger or battery cartridge are clogged with dust or the battery cartridge is worn out or
damaged.
Trickle charge (Maintenance charge)
If you leave the battery cartridge in the charger to prevent spontaneous discharging after full charge, the
charger will switch into its ''trickle charge (maintenance charge)'' mode and keep the battery cartridge fresh and
fully charged.
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 temperature at 10°C – 40°C (50°F – 104°F).
Let a hot battery cartridge cool down before charging it.
4. Charge the Nickel Metal Hydride battery cartridge when you do not use it for more than six months.
Installing or removing saw blade (Fig. 3 & 4)
CAUTION:
• Always be sure that the tool is switched off and
unplugged before installing or removing the blade.
• Always clean out all chips or foreign matter adher-
ing to the blade and/or blade holder. Failure to do so
may cause insufficient tightening of the blade,
resulting in a serious injury.
• Use a lubricant or cutting oil between the blade and
roller when cutting iron or composition board, etc.
Failure to do so will shorten the service life of your
blade and roller or lead to potentially dangerous
blade breakage.
To install the blade, loosen the bolt on the blade
holder with the hex wrench. With the blade teeth
facing forward, insert the blade into the blade holder
as far as it will go. Make sure that the back edge of the
blade fits into the roller. Then tighten the bolt to secure
the blade.
To remove the blade, follow the installation proce-
dures in reverse.
NOTE:
Occasionally lubricate the roller.
Installing universal shank jig saw blade
(Fig. 5 & 6)
CAUTION:
Always be sure that the tool is switched off and
unplugged before installing or removing the blade.
If the universal blade clamp is used, you can use
blades of other makes which have a universal shank
like the one shown in the figure, with a blade width of
6.35 mm. Insert the blade into the blade holder as far
as it will go. Make sure that the end of the blade shank
reaches the bottom of the inner slit and tighten the
bolt securely with the hex wrench.
