7.1. Adjusting the table & Rack Height
The table can be raised, lowered, and tilted
with desired angles to accommodate the work
piece.
To raise or lower the table, loosen the
lever-locks behind the table bracket, then use
the hand crank to move the table to the
desired height. Then lock the table in position.
To tilt the table, loosen the lock-lever first to
adjust the table to desired angle, then lock the
table in position.

Radial Head Position Adjustment

Change the radial position of the drill
head only if the drill press base is secured to
the floor. Swinging the drill head without the
base being secured to the floor will cause the
drill press to become unstable and tip over
resulting in injury and/or damage to the
machine.
