• 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.
