Overload Protection
In order to protect the user, the motor and the tool is equipped with an
electronic overload protection.
Electronic:
In case of overload caused by a grinding pressure
which is too high, the electronics react by switching OF
the machine. After automatic switch-OFF of the machine
you can continue working after switching OFF and ON the
power tool again.
Care and Maintenance
Before the beginning of the maintenance or repair works you
have to disconnect the plug from the mains.
Repairs may be executed only by appropriately qualified and experienced
personnel. After every repair the machine has to be inspected by an
electric specialist. Due to its design, the machine needs a minimum of care
and maintenance. However, the following points have to be observed:
Always keep the power tool and the ventilation slots clean.
During work, please pay attention that no particles get inside the
machine.
In case of failure, a repair has to be carried out by an authorised
service workshop.
Our after-sales service responds to your questions concerning
maintenance and repair of your product as well as spare parts.
EIBENSTOCK’s application service team will gladly answer questions
concerning our products and their accessories.
Replacing the flexible drive shaft:
If necessary, you can easily replace the flexible drive shaft (see Fig. 5).
To do so, press in one of the two locking pins with a suitable tool (for
example a screwdriver) (1) and at the same time pull the shaft together with
the protective hose from its holder (2).
With the locking pin depressed, insert the new shaft together with the
protective hose into the holder and turn the protective hose until the locking
pin has engaged securely.
Attention!
Check that the drive shaft is seated securely before start of operation.
Let the machine run for a short time in a safe position. Immediately
stop the work if the tool is not running smoothly.
