Overload Protection; Care And Maintenance - Makita DBM080 Manual De Instrucciones

ON-OFF Setting
The machine is equipped with an electronic ON/OFF switch. The more the switch is pressed, the higher is
the speed. This allows very precise drilling. In normal working conditions, always work at maximum speed.
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 removed 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 overload protection.
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 occur 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.
Thermal: When continuance overload is applied 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.
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 for health protection, protection against soiling and a
condition for optimal cutting conditions. We offer fitting to the DBM 080 a dust exhaust and a 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.
