2 Safety Precautions and Working Techniques
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!
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 abrasive 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 abrasive 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
0458-753-8221-D
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
– Stop switch can be moved 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
To reduce the risk of personal injury, do not
operate your power tool if it is damaged or not
properly assembled!
2.7 Starting the engine
Start the engine at least 3 meters from the fuel‐
ing spot, outdoors only.
On even ground, ensure a firm and secure foot‐
ing and hold the engine-driven device firmly – the
abrasive cutting wheel must not touch any
objects or the ground and must not be in cutting
action.
The abrasive wheel may begin to rotate as soon
as the machine is started
The machine is operated by a single person only
– do not allow any person to stay within the work‐
ing area – nor with starting.
Do not drop start your machine – the correct
starting procedure is described in the User Man‐
ual.
After releasing the throttle trigger, the abrasive
wheel keeps on running for a while – danger of
injury due to coasting effect!
2.8 Holding and guiding the
machine
The cut-off machine may only be used for hand-
held cutting or when mounted on a STIHL Cut‐
quik cart.
