Makita 4331D Betriebsanleitung Seite 7

CAUTION:
• The battery charger is for charging Makita battery cartridge. Never use it for other purposes or for other manufac-
turer'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 bat-
tery 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 ter-
minals 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 adhering 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. Fail-
ure to do so will shorten the service life of your blade
and roller or lead to potentially dangerous blade break-
age.
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 procedures in
reverse.
NOTE:
Occasionally lubricate the roller.
Selecting the cutting action (Fig. 7)
This tool can be operated with an orbital or a straight line (up and down) cutting action. The orbital cutting action
thrusts the blade forward on the cutting stroke and greatly increases cutting speed.
To change the cutting action, just turn the lever to the desired cutting action position. Refer to the table below to select
the cutting action.
Position

O
Small orbit cutting action

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.
