LEVELLING THE TABLE (AP540PD ONLY)
The 'AP540PD pillar drill' come with a large heavy cast iron
table and there is more chance that the table will need to
be adjusted so it's perpendicular with the motion of the quill.
To do this there is an adjusting nut on the supporting arm
below the 90˚ locking pin, see fig 45.

1. Position the centre of the table directly beneath the pillar
drill's chuck and lock the table in place. The table should be
about 200mm beneath the bottom of the chuck, find a
perfectly cylindrical steel rod about 12.5mm in diameter
and insert it into the chucks jaws and tighten.
2. Position a 90˚ square on the table and line it against the
steel rod. If you notice any unevenness between the table
and the rod, loosen the tilt clamping bolt and turn the
adjusting nut until the table is square with the drill chuck.
Tighten the clamping bolt to lock the table in place, see 46-47.

tensioning lever (B) anti-clockwise, to move the motor
assembly "out" . Tighten the motor yoke butterfly knobs (A)
