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).

Methods for Securing Equipment to Work Surface

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.

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 specific instructions on using anchors, see "Using an Expansion- Type Anchor".

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.

Vertical Coring (floors)

Two methods will work to secure the rig for vertical coring: either an expansion-type anchor OR a vacuum pump and vacuum pad system.

Rod or Bolt

Nut & Washer or Vacuum Pad Nut

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 the base of the Dymorig and tighten the bolt or washer and nut firmly in the anchor following the anchor manufacturer's instructions.

Securing the rig with an anchor gives better bit performance because the attachment is more rigid. For specific instructions on assembling the vacuum system, see "Assembling and Using a Vacuum System".

Optional Telescoping Assembly

The telescoping assembly can be used to supplement 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 expan- sion-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.
