Your EBM-2.1 comes with a protective guard installed. DO NOT
operate this machine without the guard in place.
Please note that when you are performing certain operations such
as removing and installing drill bits, you will need to move the
guard out of the way. Making sure the power to the machine is
disconnected or locked-out, push the guard up and hold in place
while performing necessary operations or maintenance. The pro-
tective guard should not be removed during operation.
We recommend using a piece of card stock on the Table when
leveling the drill bit to avoid drilling into the drill strip. This will
lengthen the life of your drill bits and keep them sharper.
Remove the hole guard which is attached to the chuck. This is
done by grasping the bent end and sliding the guard off.
Using the Chuck Release Key (EBM-32), insert the tapered end
facing down into the chuck hole. With a clockwise motion turn the
Chuck Release Key 45 degrees. The drill bit will slide out of the
chuck. It is recommended that you hold onto the drill bit so that it
does not drop out of the chuck damaging the tip.
To install a drill bit, grasp the drill bit, and being careful to keep it
straight, press it up into the chuck.
Seat the drill bit by using a stack of scrap paper. Set the scrap on
the table. Step on the foot pedal slowly raising the table toward
the Drill Bit. Put light pressure on the hollow Drill Bit seating it
firmly in place.
Remove the scrap paper and turn the machine on to check the
concentricity of the bit. If the bit is not concentric, remove it and
repeat steps 4.2.2 through 4.2.5 until it is concentric.
When the drill bit is correctly installed replace the hole guard back
onto the chuck to protect debris from clogging the chuck.
