The machine must not be damp and must not be operated in a wet environment.
o
Always inspect cable and plug before using machine. Only have damage repaired by a
qualified professional.

achine is switched off.
o
Always lay the cable away from the machine towards the rear.

Take care of long hair and fashion accessories; work in properly buttoned-up clothes, without
freely flowing parts.
o
To be on the safe side, always use the handle. Consider possible reaction torque.
o
Do not carry the machine by the power cord.

Before any work on the machine itself, pull the ma
ins plug.
If the cord is damaged, it should be replaced by the manufacturer or an authorized service department

Startup
•
Do not touch into the grinding head.
•
Hold the machine tightly with both hands.
•
Before switch on the machine in operation, be sure that any attachment to the handle is
closed.
•
Connect the equipment to the power supply.
•
Before starting the machine, keep away the unit fr
om the surface which will be sanded.
•
The pressure of the grinding machine to the surface should not be too big nor too low. Crucial
for an optimal sanding result is the choice of the grinding paper.
•
Turn off the machine after the grinding work.
Maintenance
o
This power tool normally requires no maintenance;
from time the ventilation holes on the
motor housing should be cleaned out.
o
After approx. 50 hours of operation, check the mot
or brushes and replace if necessary. Clean
the motor housing.
o
After approx. 200 hours of operation, renew the grease filling in the gearbox.
To verify that the protective insulation remains intact, the machine must be subjected to a technical
safety test afterwards. For this reason, this work
must be performed exclusively by a professional
workshop.
