Maintenance - Makita 4073D Betriebsanleitung

A battery short can cause a large current flow,
overheating, possible burns and even a break-
down.
7. Do not store the tool and battery cartridge in
locations where the temperature may reach or
exceed 50°C (122°F).
8. Do not incinerate the battery cartridge even if it
is severely damaged or is completely worn out.
The battery cartridge can explode in a fire.
9. Be careful not to drop or strike battery.
SAVE THESE INSTRUCTIONS.
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 Nickel Metal Hydride battery car-
tridge when you do not use it for more than six
months.
OPERATING INSTRUCTIONS
Installing or removing battery cartridge
(Fig. 1 & 2)
• Always switch off the tool before insertion or removal of
the battery cartridge.
• To remove the battery cartridge, remove the rear cover
from the cleaner by pushing it in the direction of the
arrow and then withdraw the battery cartridge from the
cleaner.
• To insert the battery cartridge, align the tongue on the
battery cartridge with the groove in the housing and slip
it into place. Snap the set plate back into place. Be sure
to close the set plate fully before using the tool.
• Do not use force when inserting the battery cartridge. If
the cartridge does not slide in easily, it is not being
inserted correctly.
Switch action (Fig. 3)
CAUTION:
• Always be sure that the dust bag or paper pack is
installed properly in the cleaner before use. Improper
installation may allow dust to enter the motor, resulting
in malfunction of the cleaner.
• Always switch off the cleaner after each use to prevent
damage to the cleaner and to lengthen the service life
of the batteries.
This cleaner can be operated in "standard" and "strong"
suction. For standard suction, slide the switch forward to
the LOW position. For strong suction, slide the switch fur-
ther to the HIGH position.
To stop the cleaner, slide the switch back to the OFF
position.
Cleaning (Suction)
Nozzle (Fig. 4)
Attach the nozzle to clean off tables, desks, furniture, etc.
Nozzle slips on easily.
Nozzle + Extension wand (Straight pipe) (Fig. 5)
The extension wand fits in between the nozzle and the
cleaner itself. This arrangement is convenient for clean-
ing a floor while standing erect.
Corner nozzle (Fig. 6)
Fit on the corner nozzle for cleaning corners and crevices
of a car or furniture.
Corner nozzle + Extension wand (Straight pipe)
(Fig. 7)
In tight quarters where the cleaner itself cannot squeeze
in, or in high places hard to reach, use this arrangement.
Dust disposal
CAUTION:
Empty the dust bag before it becomes too full, or the suc-
tion force weakens.
Depress the buttons and open the front cover. (Fig.8)
Take the dust bag out of the cleaner carefully so that the
contents will not spill out. Empty the contents out of the
dust bag. (Fig. 9)
Also empty out the dust inside the cleaner itself. Failure
to do so may cause the sponge filter to be clogged or the
motor to be damaged. (Fig. 10)
Installing dust bag
Place the dust bag into the cleaner cavity. (Fig. 11)
Insert the holder of the dust bag all the way into the slots
in the cleaner cavity. (Fig. 12)
CAUTION:
Forgetting to install the dust bag, failure to insert the
holder of the dust bag all the way into the slots or using a
broken or ripped bag, may allow dust to get into the
motor. This may result in motor failure.
Hook the front cover onto the front lip of the cleaner.
Then close the front cover. (Fig. 13)
NOTE:
• When installing the paper filter, follow the same proce-
dures for the dust bag.
• Always unfold a new paper pack before installing it on
the cleaner.

MAINTENANCE

CAUTION:
Always be sure that the cleaner is switched off and the
battery cartridge is removed before carrying out any work
on the cleaner.
After use (Fig. 14)
When storing the cleaner, hang it from a nail using the
convenient hanger in back.
Cleaning (Fig. 15)
From time to time wipe off the outside (cleaner body) of
the cleaner using a cloth dampened in soapy water.
Never use gasoline, benzine, alcohol, thinner or the like.
Discoloration or cracks may result.
Wash the dust bag in soapy water occasionally. Dry it out
thoroughly before use. An insufficiently dried bag may
cause poor suction and shorten the service life of the
motor.
To maintain product safety and reliability, repairs, mainte-
nance or adjustment should be carried out by Makita
Authorized Service Center.
