Toothed Blades, Carbide Tipped Blades And; Emergency Situations; Transport And Storage - Husqvarna K970 II Rescue Operator's Manual

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.
CUTTING BLADES
Toothed blades, carbide tipped
blades and emergency situations
Carbide tipped specialty blades are intended only for use
in rescue missions and only by trained staff.

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.
