Keep on exerting the same pressure also when you are
about to finish the cutting. Normally when you are
finishing the cutting the contact arc between the disc
and the material to be cut increases and this would
require an even greater push.
A slowdown would involve an overheating of the metal
and big burrs would appear.
The figure illustrates the piece cut at the end of the
work.
Caution:
During work the disc wears out and
must be replaced. The number of cuttings you can carry
out with the disc, so as cutting quality can considerably
vary depending on how the cuttings are carried out.
Quick cuttings wear the disc faster but reduce the burrs
and workpiece’s colouring. This is visible especially
when cutting small-bore pipes.
REPLACEMENT OF THE DISC
CAUTION
: Switch off the cut-off saw and disconnect it from the current, by removing the plug
from the socket before any adjustment, repair, maintenance work, cleansing and before
replacing the disc.
1.

2.
On the exterior of the fixed protective cap, loosen the two screws that fix the circular cover
in the central area of the disc (part 71 of the exploded view), in order to access to the disc
lock crew.
3.
Move the lower moving protective cap by hand inside the fixed one.
4. Press the lock button of the axle (
B
), indicated by the
arrow, and make the abrasive disc turn until the axle is
blocked.
5. Through the provided wrench, loosen the lock screw (
C
), by turning it anti-clockwise;
remove the screw (
