BUILT-IN DUST PROTECTION
The protective ring 12 preserves the tool socket
from dirt during operation. While inserting the
tool, take care that you do not damage the pro-
tective ring.
WARNING: Replace a damaged pro-
tective ring immediately!
To replace the protective ring 12, pull back the
locking sleeve 2. Grasp the protective ring and
pull it strongly slantwise forward. Place a new
protective ring onto the spindle and press it
hard.
INDICATION "SERVICE MAINTENANCE"
When the red light-emitting diode 10 begins to
blink while the machine operates normally, re-
placement of the brushes is needed. After ap-
proximately 8h operation, the brushes are worn
out completely and the safety switch actuates.
The machine halts and the red light-emitting di-
ode keeps blinking. Deliver the machine to an
authorised service for replacement of brushes
and preventive maintenance.
If the machine does not operate before the warn-
ing period of 8 hours is over, and the red light-
emitting diode 10 blinks, that probably means
the motor is damaged.
In case there is no light indication and the ma-
chine does not operate, that means there is no
power supply to the machine or that the auto-
matic switch or the cord are faulty.
