Spare Parts

WARNING

Risk of damage to life and limb due to not sufficient safety devices.

Several safety devices ensure safe operation of the magnet system. They must
always be in correct working condition.
Thus:

• Do not block safety devices.

• Do not remove safety devices.

• Check the operational reliability of the safety devices before working on the

magnet system.

WARNING

Risk of injury and property damage from using incorrect or defective
spare parts and accessories.

Incorrect or defective spare parts can cause serious injuries. They may cause
damaging, malfunctioning and the destruction of the magnet system.
Thus:

• Only use original equipment manufacturer spare parts.

• Only use original equipment manufacturer accessories.
