move, tighten the six (6) gib screws that secure the

cradle to the column as follows.

For Cat. No. 4125 & 4130 only.

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 diameter bits and high speed for

small diameter bits (see "Speciﬁ cations").

Selecting and Installing a Core Bit (Fig. 8)

MILWAUKEE offers both standard and premium

Dymobits designed to cut through a variety of ma-

terials including poured concrete, steel-reinforced

concrete, and prestressed concrete. Always use

clean, sharp bits.

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.

Methods for Securing Equipment to Work

Surface

NOTE: Some building materials contain steel

reinforcements. MILWAUKEE Dymobits can cut

through embedded steel, but are not recommended

for coring solid steel plates.

Horizontal Coring (walls)

For speciﬁ c instructions on using anchors, see

"Using an Expansion-Type Anchor".

Vertical Coring (ﬂ oors)

Two methods will work to secure the rig for verti-

cal coring: either an expansion-type anchor OR a

vacuum pump and vacuum pad system. Securing

the rig with an anchor gives better bit performance

because the attachment is more rigid. For speciﬁ c

instructions on assembling the vacuum system,

see "Assembling and Using a Vacuum System".

Optional Telescoping Assembly

The telescoping assembly can be used to supple-

ment either securing method.

NOTE: Vac-U-Rig

Cat. No. 4136 includes a

vacuum pump and vacuum pad. However, for some

applications, you may choose to use an expansion-

type anchor to secure the tool.

Anchors and Telescoping Assembly are not supplied

with any of the above rigs. Telescoping Assembly

can be purchased separately (see “Accessories”).

Anchors unavailable through MILWAUKEE.

1. Remove the water shut-off valve components

from the accessory bag. (The copper washers

inside the bag are for bit installation.)

2. Insert the hose adapter into the hose nut. Then

insert the rubber washer into the hose nut.

3. Insert the hose nut assembly into the shut-off

valve and securely tighten the assembly with

the supplied socket wrench; some threads on

the hose adapter will still be exposed.

4. Screw the shut-off valve assembly into the water

swivel housing on the Dymodrill motor (Fig. 8).

Hand-tighten the assembly and then tighten it

approximately 1/4 turn with an adjustable wrench

(not provided).

WARNING

To reduce the risk of injury

always secure the rig to the work surface to

help prevent personal injury and to protect

the rig. An unsecured rig could rotate during

coring and possibly cause injury.

WARNING To reduce the risk of injury

always use an expansion-type anchor during

horizontal coring. Vacuum systems can slip

when used on a vertical surface.
