5. REPLACING A CUT-OFF WHEEL
MAINTENANCE
Some helpful tips when using the metal cutting
saw
• Cut-off wheel selection. The cut-off wheel must match the material
to be cut. There are a wide variety of cut-off wheels and careful
selection will assist in the correct and safe operation of the saw.
For example, select a bar cut-off wheel for cutting solid metal
section and a metal stud cut-off wheel for cutting steel sections.
General purpose metal cut-off wheel are also available but where
possible it is better to use the correct cut-off wheel for the task
being performed.
• The abrasive cut-off wheel 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. The cut-off wheel 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 cut-off wheel
become blunt and the cutting process reduces considerably. This
is called glazing of the wheel and is due to the incorrect cut-off
wheel being used 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
cut-off wheel 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 cut-off wheel glazing and motor overload.
Note:
As the cut-off wheel wears the cutting capacity will decrease
and the depth stop may need to be adjusted.
MCS-2355
1. Swing the lower guard away to reveal
the cut-off wheel bolt and flange.
2. Push the spindle lock button and
rotate the cut-off wheel until the
spindle lock button engages.
3. Whilst holding the spindle lock button
use the hex key (supplied) to remove
the cutting disc bolt
Note:
To remove the cut-off wheel bolt,
rotate anti-clockwise.
WARNING!
ALWAYS USE GLOVES WHEN HANDLING
THE CUT-OFF WHEEL.
WARNING!
ENSURE THAT THE TOOL IS TURNED
OFF AND DISCONNECTED FROM THE POWER
SUPPLY BEFORE PERFORMING ANY OF THE
FOLLOWING OPERATIONS.
WARNING!
ENSURE THAT THE CUT-OFF WHEEL
MAXIMUM CUTTING SPEED IS RATED HIGHER
THAN THE RATED SPEED OF THE METAL CUT-OFF
SAW.
WARNING!
ENSURE THAT THE DEPTH STOP IS
ADJUSTED TO THE CORRECT HEIGHT PRIOR TO
ASSEMBLY OF THE NEW CUT-OFF WHEEL.
