Basic working techniques

WARNING! This section describes basic
!
safety directions for using a power
cutter. This information is never a
substitute for professional skills and
experience. If you get into a situation
where you feel unsafe, stop and seek
expert advice. Contact your dealer,
service agent or an experienced power
cutter user. Do not attempt any task that
you feel unsure of!
Do not pull the power cutter to one side,
this can cause the blade to jam or break
resulting in injury to people.
Under all circumstances avoid grinding
using the side of the blade; it will almost
certainly be damaged, break and can
cause immense damage. Only use the
cutting section.
Cutting plastics with a diamond blade
can cause kickback when the material
melts due to the heat produced when
cutting and sticks to the blade. Never cut
plastic materials with a diamond blade!
Cutting metal generates sparks that may
cause fire. Do not use the machine near
ignitable substances or gases.

Water cooling

Water cooling must always be used. Dry cutting causes
immediate overheating and machine and cutting blade
failure with a risk of personal injury.
At a low water pressure, for example when the water tank
is used, the restrictor can be dismantled to give the
correct water flow.
NOTICE! It is important not to use a too high water flow
without throttling as the belt can then slip.

Cutting technique

• Support the work piece in such a way that it is possible
to predict what will happen, and so that the cut
remains open while cutting.
14 – English
OPERATING
• Always hold the machine in a firm grip with both
hands. Hold it so that the thumbs and fingers grip
round the handles.
• Check that the blade is not in contact with anything
when the machine is started
• Start cutting with the machine running at maximum
speed.
• Start cutting smoothly, allowing the machine to work
without forcing or pressing in the blade. Always cut at
maximum speed.
• Cut in the same direction when cutting into an existing
cut. Avoid cutting at an angle to the previous cut,
otherwise there is a risk of the blade jamming or that
the machine can "climb in the cut" and cause a
kickback.
• Always cut from top to bottom (A).
• Remove the cutter and use a crowbar to remove the
material that remains between the cut (B).
