7.1 Removing the Chuck and Arbor
Unplug the machine from the power
source.
Lower the quill using the down feed
handle.
Rotate the spindle to align the key in
the spindle with the key hole in the
quill.
Insert the drift key (A, Fig 8) into the
aligned slots and tap lightly. Have
another person (or a protected table)
catch the chuck and arbor assembly
as it falls away from the spindle.
Fig 8
7.2 Adjusting the Depth Stop
To drill multiple holes at the same
preset depth, use the depth stop:
With the drill bit in the chuck, lower
the down feed handle to advance the
chuck to the desired point.
With your other hand, advance the
lock nuts (A, Fig 9) on the depth stop
(B) until they touch the stop bracket.
Fig 9
The drill bit will now advance only to
this point.
To release, advance the nuts
counterclockwise to the top of the
depth stop.

7.3 Changing Spindle Speeds
Loosen the locking screw on the
pulley cover, then open the cover.
A spindle speed and belt arrangement
chart is found on the inside of the belt
cover (A, Fig 10). Refer to this chart
whenever changing speeds.
Fig 10
To change spindle speeds:
Unplug the machine from the power
source.
Loosen two side bar bolts found on
each side of the head assembly. (A,
Fig 11).
Fig 11
Bring the motor base as close to the
head as possible.
Change the belts location according
the speed chart and the speed you
desire.
Tension the belt and tighten two slide
bar bolts (A, Fig 11).
Belts are properly tensioned when
finger and thumb pressure midway
between the two pulleys causes
approximately 10 mm deflection.
Close and lock the pulley cover.
7.4 Table Tilt Adjustment
Disconnect the machine from the
power source (unplug).
7
Remove the alignment pin (B, Fig 12)
first by turning the nut (A) clockwise.
Fig 12
Loosen the hex cap bolt (C) to tilt the
table.
Caution:
Only loosen the hex cap bolt slightly,
otherwise the table assembly will
separate from the column and fall.
Tighten the hex cap bolt.
The alignment pin only works at 90°
and must be reinserted when the table
is returned to 90°.
7.5 Return Spring Adjustment
Disconnect the machine from the
power source (unplug).
The return spring is adjusted at the
factory and should not need further
adjustment. If adjustment is
necessary:
Unplug the machine from the power
source.
Loosen two lock nuts (A, Fig 13)
approximately 6mm (do not remove).
Fig 13
Firmly hold the coil spring cover (B).
