3. Reset the emergency stop by pulling the button up.
4. Check that the machine doesn’t restart.
5.3.4 Pneumatic conditioning unit drop-out circuit check
The pneumatic conditioning unit drop-out circuit prevents the machine from restarting
unexpectedly after air supply to the PCU is lost and restored.
To check the PCU drop-out circuit:
1. Check that the PCU is connected to an air supply and to the FF6300.
2. Check that the air-supply lock-out is open (pulled up).
3. Press the START button.
4. Slowly open the PCU speed adjustment valve until the rotary drive engages.
5. Close (press down) the lock-out valve.
6. Check that the FF6300 stops.
7. Open the lock-out valve.
8. Verify that the machine does not automatically restart when the lock-out valve
is re-opened in step 7.
Do not operate the machine if the pneumatic conditioning unit starts in step
8. Contact CLIMAX for service recommendations.
5.3.5 Hydraulic power unit maintenance
1. Refill the HPU oil reservoir before each use.
2. Replace the oil and filter every two years.
For more information on HPU maintenance, see the HPU operator’s manual that was
included with the FF6300.
5.3.6 Dovetail and square ways maintenance
Lightly lubricate the dovetail and square ways after cleaning and after each work
session. This helps protect the machine precision surfaces from corrosion. See
Figure A-6 on page 86 and Figure A-10 on page 90 for the locations of the dovetail
and square ways.
5.3.7 Leadscrew maintenance
1. Lightly lubricate the leadscrew after cleaning, after each work session, and
periodically during operation to ensure smooth travel. For leadscrew locations,
see Figure A-6 on page 86 and Figure A-10 on page 90.
2. During operation, clean ball screws and ACME leadscrews frequently to pre-
vent thread damage to nut and leadscrew.
