Toothed Blades; Transport And Storage - Husqvarna K 1270 Manuel D'utilisation

Diamond blades and cooling
• During cutting the friction in the cut causes the
diamond blade to be heated up. If the blade is allowed
to get too hot this can result in loss of blade tensioning
or core cracking.
Diamond blades for dry cutting
• Although no water is required for cooling, dry cutting
blades must be cooled with air flow around the blades.
For this reason dry cutting blades are recommended
only for intermittent cutting. Every few seconds of
cutting the blade should be allowed to run 'free" with
no load to allow the air flow around the blade to
dissipate the heat.
Diamond blades for wet cutting
• Wet cutting diamond blades must be used with water
to keep the blade core and segments cool during
sawing.
• Wet cutting blades should NOT be used dry.
• Using wet cutting blades without water can cause
excessive heat build-up, resulting in poor
performance, severe blade damage and is a safety
hazard.
• Water cools the blade and increases its service life
while also reducing the formation of dust.
Toothed blades (Rescue)
WARNING! 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.
Government regulation requires a
different type of guarding for carbide
tipped blades not available on power
cutters – a so called 360 degree guard.
Power Cutters (this saw) use Abrasive or
Diamond blades and have a different
guarding system which does not provide
protection against the dangers presented
by wood cutting blades.
Use of this power cutter with a carbide tipped blade is a
violation of work safety regulations.
Due to the hazardous nature and exigent circumstances
involved with fire fighting and rescue operations
CUTTING BLADES
conducted by the various highly trained public safety
forces, safety professionals (fire departments),
Husqvarna is aware that they may use this power cutter
with carbide tipped blades in certain emergency
situations due to the ability of carbide tipped blades to cut
many different types of obstructions and materials in
combination without having to take time to switch blades
or machines. When using this power cutter be aware at all
times that carbide tipped blades are more kickback prone
than abrasive or diamond blades if not used properly.
Carbide tipped blades can also throw pieces of material
away from the blade.
For these reasons, a power cutter equipped with a carbide
tipped blade should never be used except by highly
trained public safety professionals who are aware of the
risks associated with its use and then only in those
exigent circumstances when other tools are deemed
inefficient and ineffective to for fire or rescue operations.
A power cutter equipped with carbide tipped blade should
never be used to cut wood in non-rescue operations. For
these applications a chainsaw or a circular saw is the
proper tool.

Transport and storage

• Do not store or transport the power cutter with the
cutting blade fitted. All blades should be removed from
the cutter after use and stored carefully.
• Store cutting blades in dry, frost free conditions.
Special care should be taken with abrasive blades.
Abrasive blades must be stored on a flat, level surface.
If an abrasive blades is stored in humid conditions,
this can cause imbalance and result in injury.
• Inspect new blades for transport or storage damage.
