• Select the required direction of rotation. The direction
of rotation can only be altered when the blade is
stationary. (DRIVE CHOICES>SET ROT. DIR.)

• Become acquainted with the saw unit's longitudinal feed
and inward feed by running these functions back and
forth a bit, make sure that the blade is not fed into the
material and that the saw unit is not run against the end
stoppers unnecessarily.
• Run the saw to its starting position and make sure that
the blade is not touching the material.
• Start running the water cooling through the system,
regulate the flow with the water regulation spigot.
• The blade rotation must be started using the double
command. This is done by holding the back arrow button
pushed in and simultaneously turning the dial for blade
rotation to the desired speed, the double command is
there in order to prevent blade rotation from being started
accidentally. When the blade rotation has started, the
blade engine power output is shown in the display on the
remote control.
• Begin by feeding the blade approximately 2-4 cm using
the regulator for inward feed.
• Following this, start the longitudinal feed by turning the
dial in the desired direction until the power output for the
blade engine is at approximately 60-65%, the reason not
cutting the guide cut with a higher power output is to
ensure that the guide cut is straight. Avoid cutting into
rebar when making the guide cut.

• After making the guide cut, subsequent cuts may be
made deeper, the depth is determined by material and
choice of blade but in normal cases the depth should be
between 4-7 cm (1.6'-2.8').
• These cuts should be made at maximum feed speed for
optimal use of the saw's capacity. If the power output for
the blade engine reaches 100%, the saw automatically
regulates the feed speed downwards in order to not
overload any connected fuses, in these cases the
regulator will keep the power output at 100%. If the power
output does not reach 100% during the following cuts,
the cutting depth may be cautiously increased.
• If the machine is run on single phase operation, the
available output is reduced and the cutting depth must be
reduced compared to three phase operation. A rule of
thumb might be to reduce the cutting depth by half.
• Often it is more time efficient to cut shallow cuts at higher
speed than to cut deep cuts at low speed. Shallower cuts
create less cutting surface and thus put higher pressure
on the blade segments, which helps to keep the blade
sharp and ensures a more efficient cutting.
• When the blade has cut through the material, it is
advantageous to feed the blade to the saw's maximum
depth, since this reduces the cutting surface and
increases pressure on the segments which makes for
more efficient cutting. Another benefit of feeding to the
maximum depth is that the over cut is shortened.

• The blade guard should always be mounted on the
saw when in operation. If the blade guard catches the
ceiling, for example during over cutting of a doorway,
one of the blade guard's gables may be temporarily
disassembled.
