Make sure that the holes in the abrasive material coincide with the dust extraction holes in the working disk.
BEFORE STARTING-UP
Make sure that:
-the power source complies with the rated parameters of the machine;
-the power cable and plug are in ideal condition;
-the power switch works correctly (check with power cable plug removed from the socket);
-all machine parts are installed properly and don’t show any damage;
-ventilation gaps are not clogged;
-the machine is connected to an appropriate and efficient dust extraction system.
START-UP

in the rear part of the machine. Set the motor speed according to the abrasive material and worked material
characteristics.
DUST EXTRACTION RATE ADJUSTMENT
Rotate ring (5) to adjust the dust extraction rate.
ABRASIVE MATERIAL REPLACEMENT
Perform operations specified in chapter “Fastening of Disks Made of Abrasive Material” in the reverse order.
RECOMMENDED ABRASIVE MATERIALS
Velcro-fastened abrasive paper disks with dust extraction holes, diameter 150mm.
MAINTENANCE
Any operations should be carried out after cutting off the power supply from the machine. After completion of
work and in all necessary cases remove dust from the machine body using a compressed air jet.
No other intervention by the user is recommended.
