Power supply
The tool should be connected only to a power supply
of the same voltage as indicated on the nameplate,
and can only be operated on single-phase AC supply.
They are double-insulated in accordance with Euro-
pean Standard and can, therefore, also be used from
sockets without earth wire.
For models 9047, 9049, 9057 and 9059, public
low-voltage distribution systems of between
220 V and 250 V
Switching operations of electric apparatus cause volt-
age fluctuations. The operation of this device under
unfavorable mains conditions can have adverse
effects to the operation of other equipment. With a
mains impedance equal or less than 0.22 (for 9047
and 9049) / 0.24 (for 9057 and 9059) Ohms it can be
presumed that there will be no negative effects.
The mains socket used for this device must be
protected with a fuse or protective circuit breaker
having slow tripping characteristics.

Installing wheel guard (Fig. 1)
When installing a depressed center wheel or an
abrasive cut-off wheel, always use a wheel guard.
Mount the wheel guard with the tab on the wheel
guard band aligned with the notch on the bearing box.
Then rotate the wheel guard 160 degrees counter-
clockwise. Be sure to tighten the screw securely.
