Securing Machine
WARNING!
Drilling machine must be properly secured to the
work surface to prevent serious injury to the op-
erator.
Movement during drilling will cause chatter of bit
against work surface, fracturing diamonds. Bit
may also bind in hole causing damage to the bit.
Vacuum Anchor method should not be used to
mount machine to a wall.
Bolt Anchor Method-to-Floor
1. Measure distance from center of anchor bolt slot in
base (Figure 2) to center of drill spindle (Figure 1).
2. To locate the anchor bolt hole, use the distance ob-
tained in Step 1 and measure from the center of the
hole that is to be drilled.
3. Drill and set

anchor bolt. Place Drilling Machine
over anchor hole and hand tighten anchor bolt.
4. Adjust 4 leveling screws (Figure 1) to stabilize base
and plumb mast. Secure machine by tightening an-
chor bolt.
Bolt Anchor Method-to-Wall
Use the same bolt anchor method procedure to anchor
as above.
Also fasten a chain to the Core Drilling
Machine and secure the chain to prevent the machine
falling and causing serious injury.

Vacuum Anchor Method-to-Floor
(RB-214 Only)
The Vacuum Anchor Method is recommended for 8
″
diameter holes or less. The Anchor Vacuum Method is
NOT recommended on rough or cracked floor conditions,
holes deeper than one bit length, or steel concentration
greater than standard rebar.
Do not use Vacuum Anchor Method to
mount machine to a wall.
1. Turn machine on its back and insert vacuum seal
(Figure 3) under machine base, inspecting first to en-
sure seal is in good condition and sealing groove is
clean.
2. Turn Drilling Machine up-right and loosen 4 base
leveling screws.
3. Plug power cord into a properly grounded recepta-
cle and turn vacuum pump ON/OFF switch to the
ON position.
4. Insert vacuum slot cap into anchor bolt slot (Figure
2) and check vacuum and hose connections.
Vacuum gauge (Figure 2) must read a minimum
of 20
″
of mercury.
5. The drilling machine should now be vacuum anchored.
If machine does not anchor, add weight by standing on
vacuum base. It should now anchor with vacuum
gauge reading 20
″
of mercury minimum. If not, check
the floor and vacuum seal (Figure 3) for leaks.
