Stihl TS 800 Instruction Manual page 7

Cut-off machine, spindle bearing
Faultless spindle bearings provide for
concentricity and axial running of the
diamond-tipped abrasive wheel – if
necessary, get it checked by a
competent dealer.
Abrasive wheels
Selecting the abrasive wheels
Abrasive wheels must be approved for
hand-held cutting. Do not use other
abrasive wheels and attachments –
danger of accident!
Abrasive wheels are suitable for
different materials: Observe the
identification of the abrasive 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 wheels with damaged
spindle bore – risk of accident!
TS 800
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".
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 bore 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 cuts! Diamond
abrasive wheels that shimmy constantly
or even only intermittently must be
replaced immediately.
Never straighten diamond abrasive
wheels.
Do not use abrasive wheels, which has
fallen to the ground – damaged abrasive
wheels may break – risk of accident!
Observe the expiration date where resin
abrasive wheels are concerned.
Fitting abrasive wheels
Inspect the spindle of the of the parting-
off grinder. Do not work with a device
whose spindle is damaged – risk if
accident!
Note the arrows indicating the direction
of rotation on diamond abrasive wheels.
Position the front pressure plate – rigidly
tighten the clamping screw – rotate the
abrasive wheel by hand and take sight
check for concentricity and axial
running.
Storing abrasive wheels
Store abrasive wheels in dry and frost-
free manner, place them on plane
ground, 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 parting-off grinder for safe-
to-operate state – 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 in engine-driven
devices 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 abrasive wheel guard
–
for tight seat – if loose, contact your
specialist dealer.
