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 flow 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 difficult to move on the
column, loosen the gib screws (see "Adjusting the
Gib Screws").
2. Fasten the mounting
bracket or the op-
tional spacer as-
sembly to the Dy-
modrill motor using
the four (4) 1/4"-20
threaded socket
head screws and
four (4) lock wash-
ers (they are the
smaller of the two
provided in sepa-
rate accessory
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
Slot
(or optional spacer assembly)
and motor assembly to the
cradle slot 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 accessory
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 motor
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").
