Cut-off machine, spindle bearing
Correct spindle bearings ensure the
concentricity and axial running of the
diamond abrasive wheel – if necessary,
get it checked by an approved dealer.
Abrasive cutting wheels
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 abrasive cutting
wheels.
STIHL generally recommends wet
cutting.
Observe the outer diame-
ter 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!
TS 410, TS 420
The permissible speed of
the abrasive cutting
wheel must be equal to or
greater than the maxi-
mum 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 cutting wheels.
Substandard and/or unapproved
diamond abrasive 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!
Observe the expiration date where
composite resin abrasive cutting wheels
are concerned.
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 rotation 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 concentricity and
axial running.
Storing cutting wheels
Store abrasive wheels in a dry and frost-
free place, on an even surface, at
constant temperature – risk of breakage
and splintering!
Always protect cutting wheels against
sudden impact with the floor or objects.
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.
