necessary, adjust the movable bushing so that the
blade ends up centred in the middle of the cut.
• Now cutting can proceed.
• When the cut is completed, first dismantle the power
cutter from the rail fixture. Secondly, dismantle the rail
fixture from the rail and store the fixture and the
machine separately in the supplied plywood box.
General tips
• Only use specially intended cutting blades for rail
cutting.
• Apply full throttle until the blade reaches top speed.
Reduce throttle to drop below the speed limitation
which reduces cutting blade vibrations when initiating
a cut to thereby produce straighter cuts. Apply full
throttle and maintain full speed until the cutting
process is completed.
• Hold the machine's handle so that the hands are in
line with the cutting blade. This to achieve maximum
cutting speed, blade service life and a straight cut.
• Mount the power cutter primarily with its right side to
the fixture, for the best chance of producing a straight
cut.
• When performing the cutting process correctly, it takes
about one minute to cut a 50 kg/m-rail and about one and a half minute to cut 60 kg/m-rail. If it takes longer,
review your cutting technique. Problems which arise
are often the result of incorrect cutting technique or
poor cutting blades.
OPERATING
Kickback
!
Kickback is the sudden upward motion that can occur if
the blade is pinched or stalled in the kickback zone. Most
kickbacks are small and pose little danger. However a
kickback can also be very violent and throw the power cutter up and back towards the user in a rotating motion
causing serious or even fatal injury.
Reactive force
A reactive force is always present when cutting. The force
pulls the machine in the opposite direction to the blade
rotation. Most of the time this force is insignificant. If the
blade is pinched or stalled the reactive force will be strong
and you might not be able to control the power cutter.
Never move the machine when the cutting equipment is
rotating. Gyroscopic forces can obstruct the intended
movement.
Kickback zone
Never use the kickback zone of the blade for cutting. If
the blade is pinched or stalled in the kickback zone, the
reactive force will push the power cutter up and back
towards the user in a rotating motion causing serious or
even fatal injury.
Climbing kickback
If the kickback zone is used for cutting the reactive force
drives the blade to climb up in the cut. Do not use the
WARNING! Kickbacks are sudden and
can be very violent. The power cutter can
be thrown up and back towards the user
in a rotating motion causing serious or
even fatal injury. It is vital to understand
what causes kickback and how to avoid it
before using the machine.
