WARNING! Overexposure to vibration can
!
lead to circulatory damage or nerve damage
in people who have impaired circulation.
Contact your doctor if you experience
symptoms of overexposure to vibration.
These symptoms include numbness, loss of
feeling, tingling, pricking, pain, loss of
strength, changes in skin colour or
condition. These symptoms normally appear
in the fingers, hands or wrists.
Cutting technique
The technique described below is of a general character.
Check information for each blade regarding individual cutting
characteristics (for example, a diamond blades requires less
feeding pressure than an abrasive discs).
• Support the work piece in such away that you can predict
what will happen and so it will not pinch.
• Check that the blade is not in contact with anything when
the machine is started
• Always cut at full throttle.
• Start cutting gently, do not force or squeeze the blade in.
• Move the blade slowly backwards and forwards.
Use a small part of the blade's cutting edge.
• Cut with the blade fully vertical – at right angles to the
work piece.
• The guard should be adjusted so that the rear section
rests against the work piece. Abrasive particles and
sparks are then collected by the guard and led away from
the user.
SAFETY INSTRUCTIONS
WARNING! Under all circumstances avoid
!
cutting using the side of the blade; it will
almost certainly be damaged, break and can
cause immense damage. Only use the
cutting section.
Do not pull the power cutter to one side, this
can cause the blade to jam or break
resulting in injury to people.
Sharpening diamond blades
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 blade causes
overheating and finally the loss of a segment (part of a cutting
blade).
Sharpen against a soft material such as sandstone or brick.
Blade vibration
The blade can become out of shape (not round) and vibrate if
a too high feeding pressure is used or if the blade is pressed
into the work piece.
A lower feeding pressure ought to stop the vibration.
Otherwise replace the cutting blade.
How to avoid kickback
WARNING! Kickback can happen very
!
suddenly and violently; kicking the power
cutter and cutting blade back at the user. If
this happens when the cutting blade is
moving it can cause very serious, even fatal
injuries. It is vital you understand what
causes kickback and that you can avoid it by
taking care and using the right working
technique.
What is kickback?
The word kickback is used to describe the sudden reaction
that causes the power cutter and cutting blade to be thrown
from an object when the upper quadrant of the blade, known
as the kickback zone, touches an object.
Kickback only occurs when the cutting blades kickback zone
touches an object.
General rules
• Never cut with the cutting blades upper quadrant, i.e. the
kickback zone.
