Makita DBM130 [8/52] Care and maintenance

Gear Shifting
Choose the proper speed according to the drill bit size used. Select at the speed selector by pressing-in,
shifting and engaging. If the selector is on “ O ”position, the speed can vary up to 1000 min
-1
. This speed
is recommended for diameter between 82 and 132 mm. If the selector is on “ OO ”position, the speed can
vary up to 2000 min
-1
and this speed is recommended for diameter up to 80 mm.
CAUTION !: - always check the drill bit manufactures recommendation for use
- gear shifting only when the machine is stopped and clockwise !
Starting a Hole
It is always easier to start a hole with centering bit. The electronic switch allows to drill at slow speeds in
order to safely introduce the bit in the material (5-10 mm). Once engaged in the material the centering
device (bit) can be removes from the machine and drilling at full speed can start then.
Overload Protection
In order to protect the operator and the machine, the unit is equipped with 3 protections against overload:
- mechanical - electronic - thermal
mechanical: If the drill bit is suddenly blocked in the hole, a clutch will slip, disengaging the bit
from the motor.
CAUTION ! In case of sudden blocking there may occure a strong turning back torque.
Therefore, for handheld use, the machine must be held with both hands and it
must be worked with full concentration. Ensure a safe stand.
Electronic: If the operator overload the machine because of excessive penetration speed,
the electronic protection will stop the electric supply for a short while. After
discharge and reengagement, one can drill again.
Thermal: When continuos overload is applied (despite the electronic device) a thermal
protection will protect the motor from destruction. When the thermal overload
protection has worked, it is not possible to start the machine immediately after. It
is only after some cooling time that the machine can be restarted. The time
needed to be able to restart the machine will be vary to the overheating of the
coil and the ambient temperature.
Acoustic warning: In case of overload, a continuis acoustic signal sounds. When this occurs, it is
recommended to decrease the and/ or cool it down while rotaring without load.
Important notice: The stop of the machine caused by overload protection is no failure. After an
adequate time it is possible to restart working!
Dust Exhaust
We recommend a dust exhaust for dry drilling. This is health protection, protection against soiling and a
condition or optimal cutting conditions. We offer fitting to the DBM130 a dust exhaust and vacuum cleaner
as special accessories.
Care and Maintenance
Before all works at the machine, make sure that the plug is off the mains socket.
Due to its design, the machine needs a minimum of care and maintenance.
Nevertheless you should always observe the following:
- Keep the electric tool clean.
- Avoid any particle or part to penetrate inside the tool.
- If the machine is defect let carry out a repair only through an authorized service workshop.
