Mounting the Meter Box
For All Catalog Nos. (Fig. 3 & 4).
A meter box is standard equipment with the Vac-U-Rig
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. (Fig. 5 & 6).
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 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 (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 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").

Adjusting the Gib Screws (Fig. 7)
After the motor is mounted, make sure the cradle and motor are rigid against
the column to prevent the motor or bit from wobbling during coring. Before
® , but it must be
coring, try to wiggle the cradle with your hands. If the cradle is secure, it
should not move. If it does move, tighten the six (6) gib screws that secure
the cradle to the column as follows.
For Cat. No. 4125 & 4130 only.
Tighten the six (6) gib screws with the hex wrench (supplied in a separate
accessory bag).
For Cat. No. 4115 & 4120 only.
To tighten the six (6) gib screws: loosen the hex nuts, tighten the screws
and then tighten the hex nuts.
Selecting and Installing a Core Bit (Fig. 8)
MILWAUKEE offers both standard and premium Dymobits designed to cut
through a variety of materials including poured concrete, steel-reinforced
concrete, and prestressed concrete. Always use clean, sharp bits.
1. To install a bit, grease the spindle and bit threads to prevent corrosion
and to help prevent the bit from seizing on the threaded spindle.
2. Slip one copper washer (provided in separate accessory bag with the
water shut-off valve components) onto the threaded spindle against
the spindle shoulder. The bag should contain an extra copper washer;
save it for future use.
3. Thread the bit securely onto the threaded spindle.
Selecting Speeds
Dymodrills operate in either high or low gear. Use low speed for large diam-
eter bits and high speed for small diameter bits (see "Specifi cations").
