Working safely with cut-off machines
English

Use composite resin cutting wheels
with or without water – depending on
version
Depending on version, composite resin
cutting wheels are suitable for dry
cutting or wet cutting only.
Composite resin cutting wheels
suitable only for dry cutting
During dry cutting, wear a suitable dust
mask.
If fumes or smoke are anticipated (e. g.,
when cutting composite materials), wear
respiratory protection.
Composite resin cutting wheels
suitable only for wet cutting
To bind dust, the cutting wheel must be
supplied with at least 1 liter of water per
minute. To avoid a reduction in cutting
performance, the cutting wheel must be
supplied with not more than 4 liters of
water per minute.
After using the cutting wheel, the wheel
should be allowed to continue spinning
at operating speed for
approx. 3 to 6 seconds without water in
order to spin off the water remaining on
it.
– Water attachment on the machine
for all types of water supplies
– Pressurized water tank 10 l for
binding dust
– water tank usable on the cut-off
machine cart for binding dust
Observe with diamond and
composite resin cutting wheels
Object to be cut
– Must be fully supported
– Must be secured so it cannot roll or
slip off
– Must be prevented from vibrating
Severed parts
With openings, recesses, etc., the
sequence of the cuts is important.
Always make the last cut so that the
cutting wheel does not become jammed
and so that the operator is not
endangered by the severed or
separated part.
If necessary, leave small ridges that hold
the part that is to be separated in
position. Break these ridges later.
Before finally separating the part,
determine:
– how heavy the part is
– how it can move after separation
– whether it is under tension
When breaking out the part, do not
endanger assistants.
Cut in several passes
N Mark cutting line (A)
N Work along the cutting line. When
making corrections, do not tilt the
cutting wheel, but always set the
cutting wheel against the workpiece
anew – the cutting depth for each
operation should not exceed 5 to
6 cm. Cut thicker material in multiple
operations
N sever large wall thicknesses with
even back and forth movements
Use cutting wheel only
with water.
