2 Safety Precautions
The desired cutting depth can be set via the
"depth stop with suction support".
2.7 Drive
2.7.1 Battery
Follow the supplement sheet or User Manual for
the STIHL rechargeable battery and keep them
in a safe place.
For further safety instructions, see

Protect STIHL batteries and the STIHL battery
belt from flying sparks when cutting steel – risk of
fire or explosions!
Keep STIHL batteries away from dirty water
(e. g. from additives or solid matter), conductive
liquids and metal objects (e. g. nails, coins, jew‐
ellery, metal chips). The batteries can be dam‐
aged – risk of fire or explosions!
Battery charger
Observe the supplement sheet for the STIHL
charger and keep in a safe place.
2.8 Cut-off machine, spindle bear‐
ing
Correct spindle bearings ensure the concentricity
and axial running of the diamond abrasive cut‐
ting wheel – if necessary, get it checked by an
approved dealer.
2.9 Abrasive cutting wheels
2.9.1 Selecting the abrasive cutting wheels
Abrasive cutting wheels must be approved for
freehand cutting. Do not use other abrasive units
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 outside diameter of the
abrasive cutting wheel – refer to the
chapter "Specifications".
Spindle hole diameter of the abrasive
cutting wheel and shaft of the cut-off
machine must match – refer to the
chapter "Specifications".
Check the spindle hole for damage. Do not use
abrasive cutting wheels with a damaged spindle
hole – risk of accident!
0458-707-9821-C
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
that there are no damaged or missing segments
and that the spindle hole is not damaged.
Never use cracked, chipped or bent abrasive cut‐
ting wheels.
Substandard and/or unapproved diamond abra‐
sive cutting wheels can shimmy during cutting.
This shimmying can cause such diamond abra‐
sive cutting wheels to be abruptly braked or
become stuck in the cut – Danger of kickback!
Kickback can result in fatal injuries! Diamond
abrasive cutting wheels that shimmy constantly
or even only intermittently must be replaced
immediately.
Never straighten diamond abrasive cutting
wheels.
Do not use an abrasive cutting wheel which has
fallen to the ground – damaged abrasive cutting
wheels may break – risk of accident!
Observe the expiration date where resin abrasive
cutting wheels are concerned.
2.9.2 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 cutting wheels.
Position the front pressure plate – tighten up the
clamping screw – rotate the abrasive cutting
wheel by hand and take a sight check for con‐
centricity and axial running.
2.9.3 Storing abrasive cutting wheels
Store abrasive cutting wheels in a dry and frost-
free place, on a flat surface, at constant tempera‐
ture – risk of breakage and splintering!
Always protect the abrasive cutting wheel
against sudden contact with the ground or
objects.
