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 FF5300 stops.
7. Open the lock-out valve.
8. Check that the machine does not automatically restart when the lock-out
valve is re-opened in step 7.
WARNING
Do not operate the machine if the PCU starts in step 8. Contact Climax
for service recommendations.
5.4.5 Dovetail ways maintenance
Lightly lubricate the dovetail ways after cleaning and after each work session. This
helps protect the machine precision surfaces from corrosion. See Figure A-5 on
page 60 and Figure A-7 on page 62 for the locations of the dovetail ways.
5.4.6 Leadscrew maintenance
Do the following to maintain the leadscrew:
1. Lightly lubricate the leadscrew after cleaning, after each work session, and
periodically during operation to ensure smooth travel. For leadscrew loca-
tions, see Figure A-5 on page 60 and Figure A-7 on page 62.
2. During operation, clean ball screws and ACME leadscrews frequently to
prevent thread damage to nut and leadscrew.
5.4.7 Adjust the dovetail ways gib screws
Adjusting the dovetail slide on the tool head is done using three M6 x 1.0 gib
screws. For screw locations, see Figure A-7 on page 62.
Adjusting the dovetail ways on the machining arm is done using three M6 x 1.0 gib
screws. For screw locations, see Figure A-7 on page 62.
The radial slide (gib screws) must be snug for the best cutting performance.
Approximately 10 in-lbs (1.13 Nm) of torque is necessary to turn the radial travel
leadscrew.
Adjustment should be necessary only after many hours of use and only if the
machine is no longer producing a good finish.
If a slide is visibly loose and causing machining problems, tighten the gib screws
in small increments. There should be 10 in-lbs (1.13 Nm) of drag on the radial
leadscrew and a slight drag on the manual feed handle.
