WARNING: The cutting blade manufacturer
issues warnings and recommendations for
the use and proper care of the cutting blade.
Those warnings come with the cutting blade.
Read and follow all instructions from the
cutting blade manufacturer.
WARNING: A cutting blade should be
checked before it is assembled on the saw
and frequently during use. Look for cracks,

Husqvarna cutting blades are high speed cutting blades
approved for hand held power cutters.
A cutting blade should be checked before it is
assembled on the saw and frequently during use.
Look for cracks, lost segments (diamond blades) or
pieces broken off. Do not use a damaged cutting
blade.
Read and obey the instructions that come with the
cutting blade.
High-quality blades are often most economical.
Lower quality blades often have inferior cutting
capacity and a shorter service life, which results in a
higher cost in relation to the quantity of material that
is cut.
Make sure that the right bushing is used for the
cutting blade to be fitted on the product. Refer to
Checking the arbor bushing on page 14 .
Test the integrity of each new cutting blade by
running it at full throttle for about 1 minute.
Correct cutting blades
WARNING: Read and follow the warning
instructions that follow before you use the
product.
Never use a cutting blade for any other materials
than what it was intended to cut.
Use only a diamond blade made for dry cutting.
Never use toothed blades such as wood cutting
blades, circular toothed blades, carbide tipped
blades, etc. The risk of kickback is significantly
increased and tips can be torn off and thrown at high
speed. Carelessness can result in serious personal
injury or even death.
Do not use a diamond blade with a lower speed
rating than that of the power cutter. Use only
diamond blades that are in compliance with national
or regional standards, for example EN13236 or ANSI
B7.1 .
705 - 002 - 12.11.2018
The cutting blade must be approved for the same or
higher speed rating than that of the product. The
speed rating is specified on the blade guard.
Many cutting blades that can be attached to this
product are made for stationary saws. The speed
rating of those cutting blades is too low for this
product.
Select a cutting blade which center hole dimension is
correct with the bushing installed on the machine.
Blade vibration
The blade can become out-of-round and vibrate if an
excessive feed pressure is used.
A lower feed pressure can stop the vibration.
Otherwise replace the blade.

Diamond blades

WARNING: Never use a diamond blade to
cut plastic material. The heat produced
during cutting may melt the plastic and it can
stick to the cutting blade and cause a
kickback.
WARNING: Diamond blades become very
hot when used. An overheated blade is a
result of improper use, and may cause
deformation of the blade, resulting in
damage and injuries.
WARNING: Cutting metal may cause fire
and damage to this product or the dust
extractor.
Note: Diamond blades are available in several hardness
classes.
Note: Sharpen the blade by cutting soft material such as
sandstone or brick.
Always use a sharp diamond blade.
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 dull diamond blade causes
overheating, which can result in the diamond
segments coming loose.
Diamond blades consist of a steel core provided with
segments that contain industrial diamonds.
Diamond blades are ideal for masonry, reinforced
concrete and other composite materials.
Diamond blades ensure lower costs per cutting
operation, fewer blade changes and a constant
cutting depth.
When using diamond blade make sure that it rotates
in the direction indicated by the arrow on the blade.
