the material to be cut. This reduces the temperature of
the blade and ensures effective cutting.
Managing dust (K 3000 Vac)
The Vac attachment is easily attached to the machine and
connected to the vacuum cleaner/dust collector for
effective dust management when dry cutting.
The amount of dust created when cutting depends on the
material being cut. Soft materials produce more dust.
Adapt the cutting speed so that the Vac attachment can
collect as much as possible of the dust that is produced.
Gradual start and overload protection
The machine is equipped with electronically controlled
gradual start and overload protection.
The engine starts to pulsate if the machine is loaded
above a specific level. If the load is reduced the engine
reverts to its normal state and cutting can resume.
The electronics will cut the current after a set time if the
machine continues to be run with a pulsating engine. The
higher load the faster the shutoff.
The electronics cut the current immediately if the blade
jams.
Kickback
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.
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.
OPERATING
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.
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
kickback zone. Use the lower quadrant of the blade to
avoid climbing kickback.
