1. After each relay cut-out (ten separate cuttings),

empty the offcut gatherer.

For safety reasons remove the battery first.

Ensure that no offcuts remain inside the switchgear

if the offcut gatherer was not used.

2. Use a file to remove any sharp edges or burrs around

the cut-out area.

3. Cover the relay compartment to avoid

spreading dust.

4. Clean dust and any remaining offcuts.
