GENERAL DRILLING GUIDELINES
To drill a hole:
1.
Mark where you want to drill in workpiece by using a centre punch or a sharp nail or turn
ON Laser Line to mark drilling point.
2.
Before turning ON the bench drill press, turn the feed handles to bring the drill bit down.
Line the drill bit tip up with the mark. Clamp the workpiece in place.
3.
Turn ON the bench drill press and pull down on the feed handles with appropriate force
needed to allow the drill bit to drill material.
Note: FEEDING TOO SLOWLY might cause the drill bit to turn in the chuck. FEEDING
TOO RAPIDLY might stop the motor, cause the belt to slip, force the workpiece loose, or
break the drill bit. Practice with scrap material to get the feel of the machine before
attempting to do any drilling operation.
To adjust drilling depth (Fig. 25)
The depth gauge controls the maximum distance the
drill bit will move up or down.
To stop the drill bit at a pre-measured depth:
1.
Rotate the upper depth knob (2) until the bottom of
the knob is aligned with the desired depth mark (5)
on the gauge scale.
2.
Rotate the depth scale lock knob (1) until it meets
the lower depth scale knob (2). The chuck will stop
after travelling downward to the selected distance.
To adjust quill (return) height (Fig. 25)
To adjust the upward distance the quill (shaft that moves up and down) can travel:
1.
Turn the feed handles until the quill is at the desired height and hold it there.
2.
Rotate the lower depth knob (3) until it rests against the bottom of the metal
gauge support (4).
WARNING:
TO PREVENT THE WORKPIECE AND THE BACKUP MATERIAL FROM
SLIPPING FROM YOUR HAND WHILE DRILLING, POSITION WORKPIECE AND BACKUP
MATERIAL TO THE LEFT SIDE OF THE COLUMN. IF THE WORKPIECE AND THE BACKUP
MATERIAL ARE NOT LONG ENOUGH TO REACH THE COLUMN, CLAMP WORKPIECE
AND BACKUP MATERIAL TO THE TABLE. FAILURE TO DO THIS COULD RESULT IN
PERSONAL INJURY.
