Leveling Screws
Nut & Washer
or Vacuum
Pad Nut
Use a 5/8" expansion-type anchor (not supplied) that
will accept a 5/8" threaded rod or bolt to secure the
base to the work surface.
1. Level the stand with the four (4) leveling screws
using the bubble level as a guide. When the stand
is level, tighten the four (4) nuts on the leveling
screws.
2. Using an expansion-type anchor, insert a threaded
rod or bolt through the slot located on the base
of the Dymorig and tighten the bolt or washer
and nut firmly in the anchor following the anchor
manufacturer's instructions.

One vacuum pad is supplied with the Vac-U-Rig
they can be purchased separately for other Dymorigs.
The vacuum pad is most effective when it is secured
to a relatively smooth surface such as poured con-
crete. If the surface is too porous or rough, the pad
may not hold securely. Before using a vacuum pad,
always check the gasket on the underside of the
pad to make sure it isn't worn, cracked or torn. If it
is, immediately replace the gasket, otherwise the
vacuum pad may not hold the rig securely. To replace
the gasket, see "Replacing Vacuum Pad Gaskets"
in the "Maintenance" section. See "Accessories" for
gasket part number.
1. To use the vacuum pad, tilt the base of the rig and
slide the vacuum pad under it so the threaded stud
goes through the hole on the end of the center slot
on the base. Then set the stand upright.
2. Position the rig as required for coring the hole.
3. Level the rig with the four (4) leveling screws using
the bubble level (4125 & 4130 only) as a guide.
When the rig is level, tighten the four (4) nuts (4125
& 4130 only) on the leveling screws. The screws
will push against the vacuum pad.
4. Connect one end of the supplied vacuum hose to
the vacuum line coupler on the vacuum pad. To do
this, pull back the collar on the hose and push the
end of the hose onto the coupler until in snaps into
place. Then, connect the other end of the vacuum
hose to the coupler on the vacuum pump following
the same procedure.
5. The vacuum pump may be set on a dry surface
away from the rig or mounted to the base of the
Dymorig as shown. However, DO NOT mount the
vacuum pump to the Dymorig when angle coring.
To mount the vacuum pump on the Dymorig, place
the small hole on the vacuum pump mounting
bracket over the vacuum pad stud on the Dymorig.
6. Plug the vacuum pump into the power source—the
pump will start automatically. Step on the vacuum
pad or the vacuum pad stud until the vacuum
pad lowers and adheres to the work surface.
7. After the pad is secured to at least 20 inches of mer-
cury vacuum, tighten the vacuum pad nut securely.
