Mounting the Meter Box
For All Catalog Nos.
A meter box is standard equipment with the Vac-U-
®
Rig , but it must be purchased separately for other
Dymorigs (see "Accessories"). Attach the meter box
to the cradle on the side opposite of the handle.
1. Slip the collar on the meter box over the stud on
the cradle.
2. Position the meter box as desired and tighten
the 1/4"-20 threaded socket head screw.
NOTE: For horizontal (wall) coring, the ammeter
gauge must face upward in view of the operator.
Otherwise, water fl ow from the water shut-off
valve might drip into the outlets on the meter box.

Mounting the Dymodrill Motor to the Stand
For All Cat. Nos.
Dymorigs include a mounting bracket which mounts
Dymodrill motors to the stand. An optional spacer
assembly is available (see "Accessories"), which
can be used when coring with any bits; but it must
be used with any bit over 10" (outside diameter).
1. To mount the motor, loosen the cradle lock.
Raise the cradle on the column using the spoked
handle to allow room for installing the bit later.
Tighten the cradle lock.
NOTE: If the cradle is diffi cult to move on the
column, loosen the gib screws (see "Adjusting
the Gib Screws").
2. Fasten the mounting bracket or the optional
spacer assembly to the Dymodrill (Fig. 5) motor
using the four (4) 1/4"-20 threaded socket head
screws and four (4) lock washers (they are the
smaller of the two provided in separate acces-
sory bag). Make sure the square key on the
mounting bracket or spacer assembly engages
with the slot on the Dymodrill motor.
3. Fasten the mounting bracket (or optional spacer
assembly) and motor assembly to the cradle slot
(Fig. 6) by inserting the four (4) 3/8"-16 threaded
socket head cap screws and lock washers (they
are the larger of the two provided in separate ac-
cessory bag) through the cradle. Place screws
through the holes from the other side of the
Dymorig and place lock washers on the side of
the mounting bracket.
After the Dymodrill motor is mounted, make sure the
cradle is rigid against the column to prevent the mo-
tor or bit from wobbling during coring. Before coring,
try to wiggle the cradle and motor with your hands.
If the cradle is secure, it should not move. If it does
move, tighten the gib screws that secure the cradle
to the column (see "Adjusting the Gib Screws").
