4.2

Shutdown of HF spindle

The  procedure  for  shutting  down  the  high  frequency  spindle  for  installation
and maintenance work is as follows:

Ü

Completely disconnect the power supply.

Ü

Completely disconnect the media supply (air and liquid).

Ü

Make sure that the shaft of the HF spindle has come to an absolute stand-
still.

If the HF spindle is being shut down to be cleaned:

Ü

Reconnect only the sealing air.

Tip: Forward the data to the controller.

u

Use the option on the frequency converter of detecting the shutdown
signal from the shaft and forwarding this to the machine controller for
evaluation.

4.3

Installation and maintenance

Ü

Carry out installation, cleaning, and maintenance work only after shutting
down the HF spindle and after the shaft has come to a standstill.

Ü

Install all safety and protective devices of the machine immediately after
completing work.

4.4

Modification and repair

Modifications  or  alterations  to  the  HF  spindle  are  only  permitted  after  prior
consultation with 

Nakanishi Jaeger GmbH

.

Only  the  service  partners  listed  in  the  “Service  and  repair

  [

}

  31]

”  section  are

authorized to open and repair the HF spindle.

Only approved accessories have been tested for operational safety and func-
tionality.

4.5

Improper operation

The high frequency spindle is only safe to operate for its designated use.

Ü

Observe the safety instructions in all sections of the manual to prevent
hazards to persons, the environment, the machine, or the HF spindle itself.

Failure to observe the safety instructions may invalidate any warranty claims
and compensation claims for damages.
