2 Safety Precautions and Working Techniques
2.4 Cut-off machine, spindle bear‐
ing
Correct spindle bearings ensure the concentricity
and axial running of the diamond abrasive wheel
– if necessary, get it checked by an approved
dealer.
2.5 Abrasive cutting wheels
2.5.1 Selecting the abrasive cutting wheels
Abrasive cutting wheels must be approved for
freehand cutting. Do not use other cutting wheels
and attachments – risk of accident!
Abrasive cutting wheels are suitable for different
materials: Observe the identification of the abra‐
sive cutting wheels.
STIHL generally recommends wet cutting.
Observe the outer diameter of the
abrasive wheel.
Spindle hole diameter of the abrasive
wheel and shaft of cut-off machine
must match.
Check the spindle hole for damage. Do not use
abrasive cutting wheels with a damaged spindle
hole – risk of accident!
The permissible speed of the abra‐
sive cutting wheel must be equal to or
greater than the maximum spindle
speed of the cut-off machine. – Refer
to the chapter "Specifications".
Before fitting a used abrasive cutting wheel,
check that it is not cracked, chipped, undercut or
uneven, and does not display any signs of core
fatigue or overheating (discoloration); check also
the spindle hole is not damaged.
Never use cracked, chipped or bent abrasive cut‐
ting wheels.
Substandard and/or unapproved diamond abra‐
sive wheels can shimmy during cutting. This
shimmying can cause such diamond abrasive
wheels to be abruptly braked or become stuck in
the cut – Danger of kickback! Kickback can result
in fatal injuries! Diamond abrasive wheels that
shimmy constantly or even only intermittently
must be replaced immediately.
Never straighten diamond abrasive wheels.
Do not use an abrasive cutting wheel which has
fallen to the ground – damaged abrasive cutting
wheels may break – risk of accident!
0458-572-0121-E
Observe the expiration date where composite
resin abrasive cutting wheels are concerned.
2.5.2 Fitting abrasive cutting wheels
Inspect the spindle of the cut-off machine. Do not
use a cut-off machine if the spindle is damaged –
risk of accident!
Note the arrows indicating the direction of rota‐
tion on diamond abrasive wheels.
Position the front pressure plate – tighten up the
tensioning screw – rotate the abrasive cutting
wheel by hand and take a sight check for con‐
centricity and axial running.
2.5.3 Storing cutting wheels
Store abrasive wheels in a dry and frost-free
place, on an even surface, at constant tempera‐
ture – risk of breakage and splintering!
Always protect cutting wheels against sudden
impact with the floor or objects.
2.6 Before starting
Inspect the cut-off machine for safe-to-operate
state – observe the respective chapters in the
User Manual:
– Check the fuel system for leaks, especially the
visible parts, e. g., fuel cap, hose connections,
manual fuel pump (only in machines with a
manual fuel pump). In case of leakage and
damage, do not start the engine – risk of fire!
Have the machine serviced by a dealer before
using it
– The abrasive wheel must be suitable for the
material to be cut. It must be in good condition
and fitted correctly (direction of rotation,
secure).
– Inspect the abrasive wheel guard for tight seat
– if loose, contact your specialist dealer.
– Smooth action of throttle trigger and throttle
trigger lockout – throttle trigger must return
automatically to idle position
– Slide control / master control lever / stop
switch must move easily to STOP or 0
– Check that the spark plug boot is secure – a
loose boot may cause sparking that could
ignite combustible fumes and cause a fire!
– Never attempt to modify the controls or safety
devices
– Keep the handles clean, dry and free of oil as
well as dirt – important for safe guiding of the
cut-off machine.
– For wet applications, provide sufficient water
