Some helpful tips when using the chop saw
•
Cutting disc selection. The cutting disc must match the material to be cut.
There are a wide variety of cutting discs and careful selection will assist in the
correct and safe operation of the saw. For example, select a bar cutting disc
for cutting solid metal section and a metal stud cutting disc for cutting steel
sections. General purpose metal cutting discs are also available but where
possible it is better to use the correct cutting disc for the task being performed.
•
Abrasive cutting discs wear. The cutting discs wear so as to constantly expose
to the material being cut clean and sharp cutting edges. This is normal.
•
During the cutting operation apply a constant and even pressure to the main
handle (17). The cutting disc (7) should be constantly cutting, and sufficient
pressure needs to be applied to keep the cutting action going. If insufficient
pressure is applied, the wheel has a tendency to clog, and the cutting edges
of the disc become blunt and the cutting process reduces considerably. This
is called glazing of the wheel and is due to the incorrect cutting disc for the
material being cut, or the cutting rate being too slow.
•
Do not overload the saw. The saw should run during the cutting operation at
close to full speed. Too much pressure being applied to the tool will slow the
motor and can cause motor failure.
•
Too much pressure being applied to the tool can also cause the cutting disc
to cut on an angle. Ensure the beginning of the cut is a gradual start and
apply the firm and constant pressure as the cut gets deeper.
•
When cutting sections, always try and cut the sections so as the actual cutting
length is as short as possible through the section. For example, angle iron
has two sections to be cut. If the material is cut where both sections are cut
at once, it is better for the cutting action than trying to cut on thin section
and then a long length cut for the next section. The longer the length of cut,
the more chance of the cutting disc glazing and motor overload.
Note:
As the disc wears the cutting capacity will decrease and the depth stop (18)
may need to be adjusted.
