CAUTION

1.3 Warning labels on the grinding machine and their meanings

The following warnings and safety alert signs have been afﬁxed to the grinding machine:

CAUTION! DANGEROUS ELECTRICAL VOLTAGE

(warning notice on the switch cabinet)

On being connected to the voltage supply (3x 400 V), the grinding

machine becomes electrically live and touching its live parts directly

could be life-threatening.

Live machine parts may be opened only by authorized, trained

personnel.

The grinding machine must be separated from the mains supply

before carrying out servicing, maintenance and repair jobs on it.

CAUTION! RISK OF INJURY FROM KNIFE

(warning notice on the polishing unit)

Work on the grinding machine involves the sharpening of knives

which could cause serious cut injuries due to their sharpness.

Protective gloves must be worn when carrying out such work, in

particular when placing the knife.

Be careful when transporting blades. Use the protective devices

provided by the knife manufacturer. Wear protective gloves and

apron.
