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
or
- 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.
