INSTALLING DRILL BITS
Open chuck jaws with chuck key (Fig 8)
Insert drill bit into chuck jaws approx. 25mm. When using
a small drill bit, do not insert it so far that the jaws touch
the arbor of the drill. Make sure that the drill bit is centred
in the chuck before tightening the chuck with the key.
Tighten all 3 holes.
Fig.8
OPERATION
DRILLING
Use clamps to hold the workpiece when drilling. The
workpiece should never be held by hand as the lips of the
drill may seize the workpiece at any time, especially
when breaking through the material being drilled.
If the workpiece is whirled out of the operator's hand,
injury may occur.
For flat work, lay the workpiece on a wooden base and
clamp it firmly down against the table to prevent it
from turning.
Using Vice
For small workpieces that cannot be clamped to the
table, use a drill press vice (not included). The vice
must be clamped or bolted to the table.
Positioning Workpiece
Always place a piece of wood on the table. This will
prevent splintering or making heavy burs on the
underside of the workpiece as the drill breaks through.
The wood must contact the left side of the column.
Round- Out Tolerance
For drilling operations requiring close tolerances,
place drill blank into chuck and check run out with
a dial indicator. If the run out is not within desired
tolerance, tap the chuck bottom with a rubber mallet
until you get the desired tolerance.
LASER BEAM (Fig 9&10
)
The light from the laser beam allows you to locate
precisely the exact location on the workpiece to be
drilled.
To start work with the laser beam the first time,
Turn off the drill press.
Insert 2xAA batteries into the battery compartment
that is located adjacent to the laser on/off switch
with the correct polarity.
Press laser on/off switch to turn the laser on
