GENERAL DRILLING GUIDELINES
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 THE WORKPIECE AND
BACKUP MATERIAL TO THE TABLE. FAILURE TO DO THIS COULD RESULT IN
PERSONAL INJURY.
TO DRILL A HOLE
1. Mark where you want to drill on the workpiece by using a centre punch or
turn ON the Laser Line to mark the drilling point.
2. Clamp the workpiece in place. Before turning on the drill, turn the feed
handles to bring the drill bit down. Line the drill bit tip up with the mark.
3. Turn on the drill and pull down on the feed handles with appropriate force
needed to allow the drill bit to drill into the 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 any drilling operation.
TO ADJUST DRILLING DEPTH (FIG 20)
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 (3). The chuck will stop after
descending to the selected height.
TO ADJUST QUILL (RETURN) HEIGHT (FIG 20)
To adjust the upward distance the quill (the shaft that moves up and down)
can travel:
1. Turn the feed handles until the quill is at the desired height & hold it there.
