Service indicator
The service indicator (5) is located on the lower part of the switch
handle. If the service indicator lights up red, the running time for a
service has been reached. It is possible to work with the machine for
a few more hours from the time the service indicator starts to light up
but will then switches off automatically. Take the power tool to a DUSS
Service Centre as soon as possible to ensure that its serviceability is
maintained.
Mechanical and electric overload protection
The machine is equipped with a mechanical and an electronic overload
protection.
Mechanical overload protection:
The safety clutch protects the user from injury if the rotating tool
suddenly jams.
Electronical overload protection:
The electronics protect the motor from being overloaded. If the contact
pressure is too high, the speed of the drill bit is reduced. This condition
is cancelled by relieving the drill bit and thus the motor. Motor and drill
bit run at nominal speed again.
If the overload lasts longer than 5 seconds, the motor is switched off
electronically. To continue work, the machine must be switched off
and on again after a waiting period of 2 seconds using the pushbutton
switch. The contact pressure must be adjusted.
Before switching the machine on again, make sure that the drill bit can
be turned easily and does not jam in the drill hole.
Lubrication
The entire machine is permanently lubricated by means of a closed
lubrication system.
Maintenance and care
Caution: Always remove the mains plug from the socket before
starting any maintenance and care work.
Clean the machine after finishing work. Also clean the chuck and apply
some dry lubricant spray. Clean the machine with a dry or damp cloth
and not with a jet of water. Ensure that no water gets into the machine.
Make sure that the ventilation slots are always clean.
Sharpening
Blunt diamond core bits should be sharpened by briefly drilling without
suction at reduced speed and without soft impact in the SP sharpening
plate. Worn or damaged diamond drill bits can be refitted by DUSS
depending on their condition. If a segment breaks off, stop working
immediately, as this will destroy the diamond core bit.
