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.
2.10 Before starting work
Inspect the parting-off grinder for safe-to-operate
state – observe the respective chapters in the
instruction manual:
– Trigger switch and trigger switch lockout must
move easily – trigger switch and trigger switch
lockout must return to initial position when
released
– 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).
– Trigger switch is locked when the trigger
switch lockout is not depressed
– Locking lever easy to set to ‚ or ƒ
– Never attempt to modify the controls or safety
devices in any way
– Keep the handles clean, dry and free of oil as
well as dirt – important for safe guiding of the
parting-off grinder.
– Check contacts in the battery compartment of
the cut-off machine for foreign matter and dirt
– Fit the battery correctly – it must engage audi‐
bly
– Do not use defective or deformed batteries
– For wet applications, provide sufficient water
The cut-off machine should only be used if it is in
full working order – risk of accident!
2.11 Switching on the machine
On even ground, ensure a firm and secure foot‐
ing and hold the cut-off machine firmly – the
abrasive wheel must not touch any objects or the
ground and must not be in cutting action.
38
The cut-off machine is a one-person unit. Do not
allow other persons to be near the machine.
Switch on as described in the Instruction Manual
– see "Switching on the machine".
After releasing the trigger switch, the abrasive
wheel keeps on running for a while – danger of
injury due to coasting effect!
2.12 During operation
Use the cut-off machine only for hand-held cut‐
ting.
Ensure you always have a firm and secure foot‐
ing.
Always hold the cut-off machine firmly with both
hands: Right hand on the rear handle – even if
you are left-handed. To ensure reliable control,
wrap your thumbs tightly around the handlebar
and handle.
When a cut-off machine with an abrasive cutting
wheel rotating is moved in the direction of the
arrow, a force is produced which causes the
machine to tip sideways.
The object to be parted-off has to be firmly sup‐
ported. Always guide the cut-off machine
towards the workpiece – never in reverse.
