Attaching the Core Bit to the Core Drill
1. Place the core bit and core drill motor on a suitable work-
bench or area that is free of clutter dirt and debris. If desired
the core drill bit can be attached to the motor after the
motor has been secured to the drill rig,
2. Before installing the core bit, make sure that thepower cord
of the core drill is unplugged from the AC wall receptacle.
NEVER install the core bit on core drill that has power applied
to it.
3. Screw the core bit onto the main shaft of the core drill by
turning it clockwise by hand until tight (Figure 16).
4. Using the supplied wrenches continue to tighten the core bit.
When using the wrenches, apply pressure in the opposite
direction to fully tighten.

NOTE
Different size wrenches may be
required depending on type of core
bit.
DM15A9C/CDM2CSA — PRE-SETUP
Method 2 incorporates drilling a hole 1/2-inch in diameter
into the drill rig support surface (wall or floor), and inserting
an expansion type anchor.
1. Using a masonry bit, drill a hole approximately ½-inch in
diameter. When drilling the hole make sure it is approxi-
mately 200 mm away from center. See Figure 14. Make
the depth of the hole so that the desired anchor is flush
or just beneath the surface
Figure 14. Baseplate Drilling Alignment
2. Insert the anchor (Figure 15) into the1/2-inch hole that
was drilled into the surface. It may be necessary to
slighty tap the anchor into the hole. For best results, a
tight fit of the anchor is required. This will keep the anchor
from pulling out.
3. Align the slot on the baseplate with the 1/2-inch hole on
the surface.
4. Insert a 1/2-inch X 4.75 (not to exceed 4.75 inches) bolt
with a 1/2-inch washer through the baseplate slot and
screw it into the anchor.
5. Fully tighten the 1/2-inch bolt to secure the drill rig. If the
drill rig does not tighten down all the way, it may be
necessary to use additional 1/2-inch flat washers to fully
secure the drill rig.
