Working safely with cut-off machines

Working with the cut-off machine
Do not stand in line with the cutting
wheel.
Do not lean too far forwards and never
bend over the cutting wheel, especially
when the deflector has been pulled
back.
Don’t cut above shoulder height.
The cut-off machine may only be used
for cutting. It must not be used as a lever
or shovel.
Do not press down on the cut-off
machine.
Always decide the cutting direction
before positioning the cutting wheel.
After that, do not change the cutting
direction. Avoid knocks and bumps with
the machine while in the cut – do not
drop the machine into the cut –
danger
of breakage!
Diamond cutting wheels: If cutting
performance begins to deteriorate,
check the sharpness of the diamond
cutting wheel, resharpen as needed. To
do this, briefly cut through abrasive
material, e. g., sandstone, aerated
concrete or asphalt.
At the end of the cut, the cut-off machine
is no longer supported by the cutting
wheel in the cut. The machine's weight
must be borne by the user, otherwise
you
may lose control of the machine!
Keep water and sludge away from
electric cables -
risk of electric shocks!
To obtain a clean cut: the cutting wheel
should be pulled into the workpiece if
possible or moved back and forth in
cutting direction. It must never be
pushed.
Work with water and wet cutting when
using diamond cutting wheels – e. g.,
use STIHL water attachment.
Depending on version, composite resin
cutting wheels are suitable for dry
cutting or wet cutting only.
Work with water and wet cutting when
using composite resin cutting wheels
that are suitable only for wet cutting –
e. g., use STIHL water attachment.
Use dry cutting when using composite
resin cutting wheels that are suitable
only for dry cutting. If composite resin
cutting wheels of this type become wet,
their cutting performance is reduced and
they become dull. If composite resin
cutting wheels of this type become wet
while working (e. g., due to puddles or
water in pipes), do not increase the
cutting pressure, but continue working
with the same pressure –
risk of
breakage! Wet composite resin cutting
wheels must be used up immediately.
Cut-off machine cart
Clear a path for the cart. If the cart is
pushed over objects, the cutting wheel
may become wedged in the cut and
shatter !
Vibrations
Prolonged use of the power tool may
result in vibration-induced circulation
problems in the hands ("white finger
disease").
No general recommendation can be
given for the length of usage because it
depends on several factors.
The period of usage is prolonged by:
– Hand protection (wearing warm
gloves)
– Work breaks
The period of usage is shortened by:
– Any personal tendency to suffer
from poor circulation (symptoms:
frequently cold fingers, tingling
sensation)
– Low outside temperatures
– Amount of gripping force (holding
the power tool tightly restricts
circulation)
The cutting wheel must
be guided straight in the
cut, without wedging.
Never exert lateral pres-
sure on the cutting wheel.
Do not use the cutting
wheel for lateral grinding
or scrubbing.
