COMMON MODIFICATIONS
21 Construction
Replace the existing subclause 21.18.1 by the following:
21.18.1 Replacement:
The switch shall be of momentary contact type.

For single phase angle and vertical grinders with a rated capacity greater than 155 mm and for single

phase straight grinders with a rated capacity greater than 130 mm, either

- the mains switch shall automatically switch off the motor as soon as the actuating member of the

switch is released and shall have no locking arrangement in the “on” position

- the tool shall not restart after an interruption of the mains supply without releasing and reactuating

the switch. In this case, a lock-on device is allowed provided that two dissimilar actions are

necessary to lock the switch in the “on” position. In addition, only a single motion to the actuating

member of the switch shall be required for the switch to automatically return to the “off” position.

The restart prevention device shall have a Safety Integrity Level SIL 1, in accordance with

EN 62061, or a performance level PL = b in accordance with EN ISO 13849-1.

For all other tools, a lock-on device is allowed provided that two dissimilar actions are necessary to

lock the switch in the “on” position. In addition, only a single motion to the actuating member of the

switch shall be required for the switch to automatically return to the “off” position.

Compliance is checked by inspection and manual test.
