Abrasive Blades; Diamond Blades - Husqvarna K6500 II Operator's Manual

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.

Abrasive blades

WARNING! Do not use abrasive blades
!
with water. The strength is impaired
when abrasive blades are exposed to
water or moisture, which results in an
increased risk of the blade breaking.
• The cutting material on abrasive blades consists of
grit bonded using an organic binder. "Reinforced
blades" are made up of a fabric or fibre base that
prevents total breakage at maximum working speed if
the blade should be cracked or damaged.
• A cutting blade's performance is determined by the
type and size of abrasive corn, and the type and
hardness of the bonding agent.
• Ensure the blade is not cracked or damaged in any
other way.
• Test the abrasive blade by hanging it on your finger
and tapping it lightly with a screwdriver or the like. If
the blade does not produce a resonant, ringing sound
it is damaged.
• Do not use damaged cutting blades. Before each
use, inspect the cutting blades for chips and
cracks. If power tool or cutting blade dropped,
inspect for damage or install an undamaged
cutting blade. After inspecting and installing the
cutting blade, position yourself and bystanders
parallellt with the rotating cutting blade and run
the power tool at maximum no load speed for 1
minute. Damaged cutting blade will normally break
apart during this time.
• Do not use worn down reinforced wheels from
larger power tools. Blades intended for a larger
power tool are not suitable for the higher speed of a
smaller tool and may burst.

Diamond blades

General
• Diamond blades consist of a steel core provided with
segments that contain industrial diamonds.
• Diamond blades ensure lower costs per cutting
operation, fewer blade changes and a constant cutting
depth.
• When using diamond blades make sure that it rotates
in the direction indicated by the arrow on the blade.
Diamond blades for different materials
• Diamond blades are ideal for masonry, reinforced
concrete and other composite materials.
• Diamond blades are available in several hardness
classes.
• Special blades should be used when cutting metal.
Ask your dealer for help in choosing the right product.
Concrete, asphalt, stone masonry,
cast iron, aluminium, copper, brass,
cables, rubber, plastic, etc.
Steel, steel alloys and other hard
metals.
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.
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.
Cutting metal generates sparks that may
cause fire. Do not use the machine near
ignitable substances or gases.
