MACHINE HEIGHT AND LEVELLING
41.16 Technical Reference Manual Chapter Issue 4, May 19
The transport height may be adjusted as low as 830mm by removing the M24
full nut on each of the legs. In the event of the transport height being adjusted
above 839mm at a later date, the M24 full nut must be refitted. The locating
collar positions the machine accurately against the V-blocks on the Locator
Plate Assembly.
NOTE
To achieve reliable SPC testing and Cp/Cpk results, the machine legs must be
secured correctly to the frame to increase the rigidity of the machine.
NOTE
The centre Mounting foot (6) is only used for initial levelling.

1. Raise the rear centre mounting foot (5) to the highest position to avoid
contact with the floor plate.

2. Move machine A into position and align it with the downline machine using
two rectangular PCBs.
3. Using recommended lifting equipment, carefully raise the machine approx-
imately 10mm off the floor. Avoid any movement in direction X and Y.
4. Check the location blocks and V-blocks on the floor plate are free to move
in X and Y.
5. Check that all four stopper bolts are fully wound in.
6. Place the floor plate under foot (3) and foot (4) of machine A ensuring the
orientation of the floor plate is correct (V-blocks upline).
7. Ensure the floor plate is positioned in line with foot (3) and foot (4) and
parallel to the rear of the printer (shown above).

8. Lower the machine onto the floor plate, ensuring foot (3) and foot (4) are
positioned correctly on the plate and clear of the location and V-blocks.
9. Place foot (6) under the front of the machine in the centre.
10. Check the orientation of foot (6) as shown above.
NOTE
Avoid the seam weld to ensure the machine is properly supported.
11. Raise the front centre levelling foot (6) to make contact with the machine.
12. Raise the front left foot (1) and front right foot (2) so they are not in contact
with the floor and the machine is supported on the centre mounting foot (6).
13. Apply pneumatic power to the machine to set the rails to the correct height
for machine levelling.
14. Place an engineering level on top of the manual tooling plate along the front
row of screws running from left to right.
15. Adjust the rear mounting foot (3) and foot (4) to level the machine in the X
direction.
16. Move the engineering level along the centre row of screws running from front
to back.
