Managing Dust - Husqvarna K6500 Manual De Instrucciones

Managing dust

The machine is fitted with DEX (Dust Extinguisher), a low
flushing water kit that offers maximum dust suppression.
Use wet cutting blades with DEX when possible for
optimal dust management. See instructions in the section
"Cutting blades".
Adjust water flow using the tap to bind the cutting dust.
The volume of water required varies depending on the
type of job at hand.
If water hoses loosen from their supply sources, this
indicates that the machine is connected to a water
pressure that is too high. See instructions under the
"Technical data" heading for recommended water
pressure.
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.
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.

OPERATING
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.
Pinching kickback
Pinching is when the cut closes and pinches the blade. If
the blade is pinched or stalled the reactive force will be
strong and you might not be able to control the power
cutter.
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. Be alert for potential movement of the
work piece. If the work piece is not properly supported
and shifts as you cut, it might pinch the blade and cause
a kick back.
