CUTTING BLADES

Diamond blades for different
materials
• Diamond blades are ideal for masonry, reinforced
concrete and other composite materials.
• We offers a number of blades for different materials in
its range. Check with your Husqvarna dealer to see
which blades are best suited for your usage.

Sharpening diamond blades

• 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.
• Sharpen the blade by cutting in a soft material such as
sandstone or brick.

Vibrations on diamond blades

• The blade can become out of round and vibrate if a
too high feed pressure is used.
• A lower feed pressure can stop the vibration.
Otherwise replace the blade.
WARNING! Never use a cutting blade for
!
any other materials than what it was
intended to cut.
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.
Cutting metal generates sparks that may
cause fire. Do not use the machine near
ignitable substances or gases.
