Working safely with cut-off machines
English
5
Position front thrust washer – tighten
tensioning nut – turn cutting wheel by
hand, in the process making a visual
inspection for radial and axial runout.
Storing cutting wheels
Store cutting wheels in a dry, frost-free
place, on a flat surface, at constant
temperatures –
danger of breakage
and shattering!
Always protect cutting wheels against
sudden impact with the floor or objects.
Before starting
Check that the cut-off machine is in good
condition - refer to the corresponding
chapters in the Instruction Manual:
–
The cutting wheel must be suitable
for the material to be cut. It must be
in good condition and fitted correctly
(direction of rotation, securely
seated).
–
Check that the deflector is secure -
consult a STIHL servicing dealer if it
is loose
–
The throttle trigger and throttle
trigger interlock must move easily –
throttle trigger must return
automatically to the idle position
when released
–
Slide control / master control / stop
switch must move easily to
STOP
or
0
–
Check that the spark plug boot is
secure. A loose boot can lead to
flying sparks which may ignite the
escaping fuel/air mixture –
risk of
fire!
–
Never attempt to modify the controls
or safety devices
–
Keep the handles dry and clean –
free from oil and dirt – for safe
control of the cut-off machine
The machine should only be used if it is
in good working order –
risk of
accident!
Starting the engine
Move at least 3 meters away from the
place at which the machine was refueled
and never start the machine in enclosed
spaces.
The machine may only be used on level
ground. Ensure a firm and secure
footing and hold the machine firmly. The
cutting wheel must not touch any objects
or the ground and must not be in the cut.
The cutting wheel may begin to rotate as
soon as the machine is started.
The machine is operated by only one
person. There should not be any other
person within the working area, not even
when starting the machine.
Do not drop-start the engine – start as
described in the Instruction Manual.
The cutting wheel continues to run for
some time after the throttle trigger has
been released –
Risk of injury due to
coasting effect!
Holding and guiding the machine
The cut-off machine may only be used
for freehand cutting or when mounted on
a STIHL cut-off machine cart.
Hand-held cutting
Always hold the machine
firmly with
both hands
: Right hand on the rear
handle – even if you are left-handed. To
ensure reliable control, wrap your
thumbs tightly around the handlebar and
handle.
When a cut-off machine with rotating
cutting wheel is moved in the direction of
the arrow, a force is produced which
causes the machine to tip sideways.
The object that is to be cut must be
positioned firmly; always guide the
machine to the workpiece – never vice
versa.
Cut-off machine cart
STIHL cut-off machines can be mounted
on a STIHL cut-off machine cart.
