Pilot method
This method is recommended when attempting to cut
absolutely straight and square.
For best cutting economy, pre-cut with a power cutter
equipped with Husqvarna's special pre-cutting blade
intended for further cutting with diamond chain saw.
•
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 the hand guard as a break
point/stop.
Pendulum technique
•
The cut is made using a pendulum motion and the
saw is only held straight at the ends of the cut. Use the
hand guard as a break point/stop.
Cutting holes
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.
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!
•
First make the lower horizontal cut. Now make the
upper horizontal cut. Finish with the two vertical cuts.
•
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.
Kickback
Kickback is the sudden upward motion that can occur if
the chain is pinched or stalled in the kickback zone. Most
kickbacks are small and pose little danger. However a
kickback can also be very violent and throw the power
cutter up and back towards the user in a rotating motion
causing serious or even fatal injury.
!
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.
NOTICE! If the upper horizontal cut is made before the
lower horizontal cut, the work piece will fall on the
diamond chain and guide bar and jam it.
!
WARNING! Kickbacks are sudden and
can be very violent. The power cutter can
be thrown up and back towards the user
in a rotating motion causing serious or
even fatal injury. It is vital to understand
what causes kickback and how to avoid it
before using the machine.
