General Working Instructions - Husqvarna K3000 Cut-n-Break Operator's Manual

Water cooling
• Water cooling must always be used. This cools the blades
and increases their life and prevents dust build-up.
WARNING! Cool diamond blades designed
!
for wet cutting continuously with water to
prevent heating, which can deform the
diamond blade resulting in damage to the
machine and personal injury.
Blade vibrations
• The blades can become out of true and vibrate if a too
high feed pressure is used.
• A lower feed pressure can stop the vibration. Otherwise
replace the blades. See the instructions under the
heading Assembling the blades.
• The blades shall be intended for the material to be cut.
Material
• Diamond blades are ideal for masonry, reinforced
concrete and other composite materials. Diamond blades
are not recommended for cutting metal.
• Diamond blades are available in several hardness
classes. The blades shall be intended for the material to
be cut. A "soft" diamond blade has a relatively short
service life and large cutting capacity. It is used for hard
materials such as granite and hard concrete. A "hard"
diamond blade has a longer service life and reduced
cutting capacity, and should be used for soft materials
such as brick and asphalt.
Sharpening diamond blades
• Diamond blades can become dull when the wrong feeding
pressure is used or when cutting certain materials such as
heavily reinforced concrete. Working with a blunt diamond
blade causes overheating, which can result in the
diamond segments coming loose.
• Sharpen the blade by cutting in a soft material such as
sandstone or brick.
High speed handheld machines
• Only use special blades with integrated belt pulley halves
on this machine.
• The blades should be marked with the same or a higher
speed than that stated on the machine's rating plate.
Never use blades at a lower speed rating than that of the
power cutter.

SAFETY INSTRUCTIONS

General working instructions

WARNING! This section describes basic
!
safety directions for using a power cutter.
This information is never a substitute for
professional skills and experience. If you get
into a situation where you feel unsafe, stop
and seek expert advice. Contact your dealer,
service agent or an experienced power
cutter user. Do not attempt any task that you
feel unsure of!
Water cooling
Water cooling must always be used.
At a low water pressure, for example when the water tank is
used, the restrictor can be dismantled to give the correct
water flow.
NOTE!
It is important not to use a too high water flow without
throttling as the belt can then slip.
Cutting technique
• Support the work piece in such a way that it is possible to
predict what will happen, and so that the cut remains open
while cutting.
• Always hold the machine in a firm grip with both hands.
Hold it so that the thumbs and fingers grip round the
handles.
• Check that the blade is not in contact with anything when
the machine is started
• Start cutting with the machine running at maximum
speed.
• Start cutting smoothly, allowing the machine to work
without forcing or pressing in the blade. Always cut at
maximum speed.
