-Description:
Transmission belt skiving, with motor-driven abrasive roller and manual table advance with
inclination adjustment for various bevelling angles. Abrasive roller height adjustment using an
eccentric shaft.
-Connecting to the mains supply:
The machine should be connected to a 2-phase 230V mains electricity supply, depending on the
voltage stated on the technical specifications plate, together with the corresponding earth
connection. Attention must be paid to the motor rotation direction.
-Technical Characteristics:
•Dimensions 592x460x445mm (L x W x H)
•Weight 32Kg
•Roller width 270 mm
•Bevel travel 180 mm
•Roller diameter 100 mm
•Maximum thickness 8 mm
•Revolutions 490 rpm
•Bevel angle from 0º to 3.5º (30 Points)
•Motor 0.75KW 5.6Amp 2 Phases 230V
-Usage instructions:
Once the mains supply connection has been made, it should be verified that the motor is rotating
in the correct direction, (if it does not, then the connections for two of the phases should be
reversed).
Fit the adhesive tape over the white nylon plate in the working zone, just as shown in the figure.
This operation is essential to obtaining a good finish since it will prevent stretching and breaking
during the process:

The belt should be passed under the retaining bar up to the edge of the table, adhering the end to
be bevelled on the adhesive tape just at the table end, as shown in the following photo:
Fix the belt in place using the bar by means of the knobs (A) always attempting to maintain
parallelism with the table, in other words, performing this operation on both sides at the same
time and in the same proportion.
We then adjust the bevelling angle as given in the values table (Page 7), releasing the milled knob
towards the outside of the machine as shown in the diagram and turning it to the required point
and then locking it again:

Changing and adjusting the abrasive ape:
We also recommend that the polycarbonate protection is removed to provide more working
space and to avoid any damage to this protection.
When changing the abrasive belt, the machine must be disconnected from the mains electricity
supply in order to guarantee a safe working environment. Once this has been done, the motor head
should be fully opened roller cover protection:
