Adjusting the Height of the Work Table
Loosen the table support locking handle then use the table crank handle
to raise or lower the table to the desired height allowing clearance for the
drill bit above the work piece. To secure the table, tighten the table support
locking handle

The chuck can now be fitted to the arbor. Before fitting the chuck, both
the taper of the arbor and the corresponding taper in the rear of the chuck
should be thoroughly cleaned to remove any foreign bodies that may
prevent the chuck from seating correctly. Clean both surfaces with white
spirit to remove any heavy deposits of grease and dirt and then apply a thin
coat of silicon spray or similar to both tapers before assembling. Once the
chuck is in position, tap it firmly and squarely with a soft faced mallet to
ensure it is fully seated on to the spindle
(Fig. 7.9)
.
To fit the chuck guard, place it onto the collar of the spindle sleeve
(Fig.
7.9
), ensuring the transparent guard is positioned at the front. Tighten the
pre-installed M5 x 20 mm pan head screw to the nylon locking nut at the
rear of the chuck guard
