Cut-off machine, spindle bearing
Correct spindle bearings ensure the
concentricity and axial running of the
diamond-tipped abrasive wheel – if
necessary, get it checked by an
approved dealer.
Abrasive wheels
Selecting the abrasive wheels
Abrasive wheels must be approved for
hand-held cutting. Do not use other
cutting wheels and attachments – risk of
accident!
Abrasive wheels are suitable for
different materials: Observe the
identification of the abrasive wheels.
STIHL generally recommends wet
cutting.
Check the spindle hole for damage. Do
not use cutting wheels with a damaged
spindle hole – risk of accident!
Before fitting a used abrasive 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 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 a cutting wheel which has
fallen to the ground – damaged cutting
wheels may break – risk of accident!
Observe the expiration date where resin
abrasive wheels are concerned.
Fitting abrasive wheels
Inspect the spindle of the cut-off
machine. Do not use a 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 clamping screw – rotate
the cutting wheel by hand and take a
sight check for concentricity and axial
running.
Storing abrasive wheels
Store cutting wheels in a dry and frost-
free place, on an even surface, at
constant temperature – risk of breakage
and splintering!
Always protect the abrasive wheel
against sudden contact with the ground
or objects.
Before starting
Inspect the cut-off machine to check that
it is in full working order – observe the
respective chapters in the instruction
manual:
–
Check the fuel system for leaks,
especially the visible parts, e.g.,
filler cap, hose connections, manual
fuel pump (only on 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 servicing
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 cutting wheel guard for
tight seat – if loose, contact your
specialist dealer.
Observe the outer diame
-
ter of the abrasive wheel.
Spindle hole diameter of
the abrasive wheel and
shaft of cut-off machine
must match.
The permissible speed of
the abrasive wheel must
be equal to or greater
than the maximum spin
-
dle speed of the cut-off
machine. – Refer to the
chapter "Specifications".
