which must be in perfect condition.
- Never use makeshift and/or faulty power cables.
- Make electrical connections on the construction site where they will
not be subject to damage. Never stand the saw on power supply cables.
- Lay power cables where they are not subject to risk of damage or
contact of connectors with water. Only use connectors fitted with water-
spray protection (IP55).
- Repairs to electrical installations must only be carried out by qualified
technicians. Always ensure that the machine is disconnected from the
