Cutting blades for handheld high speed
power cutters
WARNING: Only use diamond blades. Do
not use blades with serrations such as
circular wood cutting blades or blades with
carbide tips. The risk of kickback is
increased and carbide tips can come off and
be thrown at high speed. This can result in
injury or death.
WARNING: Incorrect use can cause the
blade to become too hot. A blade that is too
hot can cause malfunction, which can cause
damage and injury.
WARNING: Do not use a cutting blade with
a lower maximum speed than that of the
power cutter. Only use cutting blades that
are in compliance with national or regional
standards.
Note: Only cut materials approved in the instruction
supplied with the blade.
Check that the blade is approved for the same or higher
speed written on the type plate of the power cutter.
Cutting blade vibration
CAUTION: If you use the product with too
much force, the cutting blade can become
too hot, bend and cause vibrations. Use the
product with less force. If the vibrations
continue, replace the cutting blade.
To sharpen the cutting blade
Note: For the best cutting results, use a sharp cutting
blade.
• To sharpen the cutting blade, cut into soft material,
such as sandstone or brick.

Diamond blades for wet cutting
CAUTION: Always use a blade flange
dimension that is specified for the current
blade dimension. Do not use blade flanges
that are damaged.
During the operation, the friction causes the diamond
blade to become very hot. If the diamond blade
becomes too hot, it will decrease the blade tension or
make the core crack.
Let the diamond blade become cool before you touch it.
• Diamond blades for wet cutting must be used with
water to keep the diamond blade core and segments
cool during cutting. Diamond blades for wet cutting
can not be used dry.
• If you use diamond blades for wet cutting without
water, the diamond blade can become too hot. This
gives bad performance, blade damage and is a
safety risk.
Diamond blades for dry cutting
• For diamond blades for dry cutting it is necessary to
have a sufficient airflow around the cutting blade to
decrease the temperature. Because of this, diamond
blades for dry cutting are recommended only for
intermittent operation. After some seconds of
operation, it is necessary to let the diamond blade
rotate freely, away from the cut. This lets the airflow
around the blade decrease the temperature of the
diamond blade.
Diamond blade - requirements
WARNING: Make sure the diamond
segment (T1) is wider than the blade (T2).
This is to prevent pinching in the cutting slot
and a kickback.
