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

One vacuum pad is supplied with the Vac-U-Rig
and 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 concrete. 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" sec-
tion. 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 cen-
ter 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.
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 mount-
ing 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 vac-
uum 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.
WARNING
read a minimum of 20 inches of mercury
vacuum. To reduce the risk of injury DO NOT
CORE if the gauge reads less than 20 inches
of mercury vacuum.
Using an Expansion-Type Anchor
For Cat. No. 4115 & 4120 only.
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. Remove the rubber
gasket from the base.
2. Level the rig with the
four (4) leveling screws.
3. Using an expansion-type anchor, insert a
threaded rod or bolt through the slot located in
the base of the Dymorig and tighten the bolt or
washer and nut fi rmly in the anchor following the
manufacturer's instructions.
