g)
If a disc saw is used for cutting, care must be taken that the thickness of the
cutting blade matches to the diamond chain. Never use a disc saw with a
conventional cutting disc for cutting. The narrow saw groove produced in this case
leads to a jamming of the diamond chain and can lead to dangerous kickback.

Chain saw and diamond chain
a)
Before starting check the chain saw for damage, loose or incorrectly mounted
parts. The saw must not be used in the above case.
b)
Before starting the chain saw, check the cover and the splash guard for damage
and correct assembly. The cover and splash guard provide protection against moving
parts, water and concrete sludge. Replace the cover or splash guard if damaged.
c)
Before starting the machine, check the diamond chain for correct assembly and
damage in the form of loose joints, broken segments or chain links. Damaged
diamond chains can lead to personal injury.
d)
Only use such diamond chains that fulfil all requirements of this chain saw.
e)
The permissible cutting speed of the diamond chain must be at least as high as
the cutting speed specified in this manual at maximum engine speed.
Accessories that turn faster than allowed can break and parts can fly around and can
lead to personal injury.
f)
Observe the cutting direction of the diamond chain. Mount the diamond chain in
that way that the direction of rotation coincides with the direction of rotation of the shaft
on which the drive wheel is mounted. The direction of rotation is indicated by an arrow
on the device. Diamond chains with any cutting direction can be mounted in both
directions.
g)
The selection of the diamond chain must be made according to the material that
has to be machined. The chain saw must not be used for sawing other materials for
which it is not intended. It must not be equipped with a chain for sawing wood.
3)
Cutting technique
a)
Care for safe standing and keep the balance anytime. Always hold the machine
in a firm grip with both hands.
b)
When sawing, always stand parallel to the bar. Do never stand directly behind
the bar as the saw will move in the plane of the bar in case of a kickback. Never
use the kickback area of the chain saw for cutting.
c)
Never cut above shoulder height.
d)
Do not use the chain saw from a ladder. Use a scaffolding if you are cutting above
the shoulder height.
e)
Check that the diamond chain is not in contact with anything when the machine
is started.
f)
Avoid blockage of the bar and the diamond chain by excessive pressure, lateral
stress and excessively deep cuts. Let the machine work without excessive force.
Lateral loading of the bar and the diamond chain can lead to material and personal
injury.
g)
Support the work piece in such a way that no unpredictable movement is
possible, and so that the cut remains open while cutting.
h)
When cutting openings, first perform the lower horizontal cut, then the two vertical cuts.
Finish with the upper horizontal cut. If the upper horizontal cut is carried out before the
lower one, the cut-out unit falls onto the cutting equipment and jams or damages it.
i)
Arrange the splash guard in such a way that the splashes and sparks entrained
by the workpiece are caught and guided away by the user.
