SAFETY INSTRUCTIONS
Safety
Plan the work so that you do
not get crushed by the bar
when the pieces fall apart.
Planning is also extremely
important for your own safety!
As it is usually a question of
large and heavy pieces that
are cut when using the
diamond chain saw the forces
are so great that jamming can
result in irreparable damage
to both the bar and chain.
You must plan before you
start to cut how to support the
workpiece according to how
the pieces separate once
cutting has been completed.
In those cases where it is
difficult to calculate how the
pieces will fall apart, or when
it is impossible to support the
workpiece as you would like,
wedging in the cut slot is a
good and safe method.
Cutting holes
A common task for the
diamond chain saw is making
small openings in thick walls.
The order in which the cuts
are made is probably obvious,
but it should be pointed out:
Start with the lowest cut
followed by the sides and
finish with the uppermost cut.
The risk of jamming is then
avoided.
Bracing
When cutting out large holes
it is important that the piece to
be cut out is braced so that it
cannot fall against the
operator.
Methods will naturally vary
according to circumstances.
One way is to drill a hole in
the piece to be cut out and
then bolt planks on both
sides.
Efficient cutting
!
Pilot method
This method is recommended when attempting to cut
absolutely straight and square.
It is appropriate to start by securing a board where the cut is to
be made. This serves as a guide for the cut. Cut to a depth of a
few centimetres along the entire line, using the lower section of
the tip of the bar. Go back and cut another few centimetres.
Repeat until a depth of between 5–10 centimetres is reached,
depending on precision demands and the thickness of the object.
The pilot cut guides the bar straight during continued cutting,
which takes place according to the plunge-cut method until full
depth is reached, use a rubber block as a break point/stop.
Pendulum technique
The entire cut is then made using a pendulum motion and the
saw is only held straight at the ends of the cut.
Generally you should attempt to get the chain to cut over
distances that are as small as possible. The partial pressure will
then be higher and the cutting process will then be faster.
In principle there are two ways to start the process of entering a
thick object to be cut.
Plunge-cut method
Start by making a 10 centimetre deep cut in the wall using the
lower part of the tip of the bar. Straighten up the saw at the
same time as the tip of the bar is inserted in the slot. Raising
and lowering the saw at the same time as it is pressed into the
wall provides an effective method of cutting to the full depth.
WARNING!
Never use a power cutter with a standard
cutting blade for pilot cutting. The cutting
blade produces a pilot slot that is too thin and
continued cutting with the diamond chain
saw results infallibly in dangerous kickback
and jamming in the slot.
