Drill Bit Removal And Installation
Page 07
Remove the hole guard which is attached to the chuck. This
is done by grasping the tab and sliding the guard off.
Step #1
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 spindle. It is recommended that you hold onto the
drill bit so that it does not drop out of the spindle damaging the
tip. Place the hole guard back onto the chuck to protect debris
from clogging the spindle.
Step #2
To install a drill bit, grasp the drill bit and being
careful to keep it straight, press it up into the Chuck.
Step #3
Seat the drill bit by using a stack of scrap paper. Set the
scrap on the table as shown. 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 concen-
tric, remove it and repeat steps 3 and 4 until it is concen-
tric.
Step #4
Note: Please note that drill bits may be hot after drilling. Please wait to
change drill bits until they have cooled down.
