Safety instructions

Maintenance may be carried out only by qualified personnel.

Unless otherwise specified, all maintenance is to be carried out with the machine turned off. In
particular, make sure that the main switch (see Chapter 5: Controls and Use) is in the “0” off position and
that all residual air present in the pneumatic system has been vented using the cut-off valve (see
Chapter 5: Turning the machine on and off).

Both the main switch and the cut-off valve are blocked using locks to prevent machine start-up.

NOTE

Safety warning

DANGER!

Electrocution hazard

The machine must be turned off before any maintenance is carried out. Live parts or
pressurized parts may cause very serious injury.

Turn off the machine and cut-off the air supply.

Block the main switch and the cut-off switch with locks.

NOTE

Safety warning

DANGER!

Crushing hazard

The balancing cylinders remain pressurized even after the main valve has been cut-off.

Do not tamper with the relative pneumatic tubes to avoid sudden movements of the
machining head.

NOTE

Safety warning

DANGER!

Risk of injury and damage to the machine

Never use compressed air to clean the machine. The jet of air may push chips
and dust into the milling unit or under the contacts of the electric components in
the electrical cabinet.

Clean the machine using an industrial vacuum!
