ADJUSTMENTS
FIG. 22
ADJUSTING THE SPINDLE RETURN SPRING
The Chuck will automatically return upward to its
original starting position when the operating handle is
released. The Return Spring Mechanism, FIG. 22,
has been preset at the factory and should not require
any adjustments. However, should the spring tension
decline and need adjustment, follow these steps;
1. Disconnect the Drill Press from its power source.
2. Loosen the Spring Cover Nuts (#47, FIG. 22, A),
but DO NOT REMOVE the nuts from the threaded pin.
3. Carefully pull out the Spring Cover (#48, Fig. 22,
B) slightly, and keep a firm grasp on it - DO NOT
LET THE COVER SPIN as it keeps the spring from
unwinding. Also, DO NOT let the spring end (C)
disengage from its notch in the spring cover!
4. Pull out the cover just enough so that the notch in
the cover clears the nub on the head casting (D).
OPERATION
CONTROL PANEL
ON/OFF SWITCH.
The ON/OFF safety switch is
located on the front of the drill press head for quick,
easy and safe access. FIG. 23, A.
1. Turn the machine “ON” by moving the power
switch to the up position. The RPM speed can then
be increased to the desired speed for the particular
drilling job, or material being worked, by rotating the
Speed Control Handle on the left side of the head.
2. Before turning the drill press OFF, it is recommend-
ed to turn the RPM Speed down to its slowest RPM
setting to prepare the machine for its next use. Then
move the power switch down to the OFF position.
3. Unplug the Drill Press from the power source when
the machine is not in use, for safety measures.
NOTE:
To prevent unauthorized use of the machine,
the power switch has a removable locking key. With
the power switch in the “OFF” position, pull the lock-
ing key out. The drill press cannot be turned “ON” with
the key removed. Insert the locking key back into the
power switch to resume drilling operations.

5. Rotate the cover to another notch as needed -
CLOCKWISE to decrease the spring tension, and
COUNTER-CLOCKWISE to increase spring tension.
6. With the cover set in the new position, push it back
in place and tighten the spring cover nuts back against
the cover to complete the adjustment.
FIG. 23
SPEED RPM DIGITAL READOUT
(B) displays the
Chuck’s RPM as set by the Motor Speed Handle (C)
(see page 14).
NOTE:
Speeds indicated may
fluctuate slightly during use, as the RPM reader is
constantly calibrating the spindle rotation.
