CALIBRATIONS
Chase to Table
Level
NOTE
This procedure requires the use of a special DEK Test Plate, therefore contact
DEK Customer Support before commencing.
The chase to table level is checked by measuring down to 5 points on the rising
table surface from a special DEK Test Plate which simulates a screen fitted in
the chase.
A datum reading is taken from the centre hole E, the range of readings must not
exceed 0.15mm of the datum.

Chase to Table
Level Adjustment
If adjustment is required, the bearing roller(s) at the appropriate corner may be
adjusted to obtain the correct depth range.
NOTE
Be careful that this does not result in one corner of the chase ‘floating’, ie load
not being spread evenly over the four support rollers.
1. Slacken the two locking screws using a 2.5mm Allen key.
2. Using a 4mm Allen key through the access hole in the locking collar, turn the
adjuster screw, which also turns the adjuster and the locking collar. This
action raises and lowers the roller bearing assembly by the amount indi-
cated by the chase to table level check.
3. Verify that the correct setting has been achieved.
