Securing the Drill Rig Assembly
Secure the Drilling Rig as follows:
DO NOT
attempt to use this unit until it has been securely
anchored to a suitable surface. The possibility exists of
severe bodily harm and damage to the equipment if the
core drill bit becomes stuck or binds thus causing the unit
to tip over.
DANGER - Drill Rig Tipping
This drilling rig can be secured by various methods. Please
read the next few paragraphs to determine which method
best suits your application.
Method 1
incorporates the use of a
vacuum pump
. The
vacuum pump will provide the necessary suction when used
in conjunction with the supplied rubber gasket seal.
1. Lay drilling rig in the down position so that access to base
plate is possible.
2. Make sure rubber gasket seal is placed evenly into base
plate groove as shown in Figure 11. For best results
apply a little water to the seal. Applying water to the seal
will make a tighter suction when the vacuum pump is
turned on. If seal is worn or damaged, replace with a new
one.
3. Return the drilling rig to its upright position.
4. Insert supplied vacuum adapter pad into slot on base of
drilling rig as shown in Figure 12.

5. On the vacuum pump there is a vacuum hose (Figure 13).
Connect the free end of the vacuum hose to vacuum line
hose fitting located on the baseplate.

6. Plug the power cord on the vacuum pump into a 120
VAC, 60 Hz power source. The unit will turn on immedi-
ately, there is no OFF/ON switch.
7. Step on the base until it lowers and adheres to the work
surface.
8. Tighten the leveling screws (4) only enough to eliminate
rocking. Over-tightening can lift the gasket off the ground
and release the vacuum.
DO NOT
attempt to use this unit until
the vacuum guage reads a minimum
of 20 in. Hg . The possibility exists of
the gasket vacuum seal being broken
and the unit tipping over.
