GENERAL POWER TOOL SAFETY WARNINGS WARNING READ ALL SAFETY WARNINGS AND ALL INSTRUCTIONS. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury. Save all warnings and instructions for future reference. The term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool. attached to a rotating part of the power tool may result in personal injury. •Do not overreach.
•WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are: • lead from lead-based paint • crystalline silica from bricks and cement and other masonry products, and • arsenic and chromium from chemically-treated lumber. Your risk from these exposures varies, depending on how often you do this type of work.
GROUNDING SYMBOLOGY WARNING Improperly connecting the grounding wire can result in the risk of electric shock. Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. Do not modify the plug provided with the tool. Never remove the grounding prong from the plug. Do not use the tool if the cord or plug is damaged. If damaged, have it repaired by a MILWAUKEE service facility before use.

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.
move, tighten the six (6) gib screws that secure the cradle to the column as follows. For Cat. No. 4125 & 4130 only. Fig. 7 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.
One vacuum pad is supplied with the Vac-U-Rig® and they can be purchased separately for other Dymorigs. The vacuum pad is most effective when it is secured to a relatively smooth surface such as poured concrete. If the surface is too porous or rough, the pad may not hold securely. Before using a vacuum pad, always check the gasket on the underside of the pad to make sure it isn't worn, cracked or torn. If it is, immediately replace the gasket, otherwise the vacuum pad may not hold the rig securely.
Assembling and Using a Vacuum System For Cat. No. 4120 only. Fig. 14 7. Tighten the four (4) leveling screws only enough to eliminate rocking. Over-tightening can lift the gasket off the ground and release the vacuum.

To reduce the risk of injury DO NOT CORE if the gauge reads less than 20 inches of mercury vacuum.
time. The spindle must be smooth without grooves or pitting. If the spindle is not in good condition, it is possible for the threaded spindle sleeve and the internal spindle to weld together and seize during coring (see "Lubricating the Spindle for Dymodrills with a Shear Pin" in the "Maintenance" section for spindle lubricating instructions).

3. After removing the core, reinsert the bit or use a bit extension and continue coring (see "Accessories"). Removing cores with diameters greater than twice their length can be difficult. One method to remove such cores is to first break the core into smaller pieces and then remove the pieces. Electric hammers and chisels are ideal for breaking cores. WARNING When coring through floors, cores generally drop from the bit.
Sharpening Procedure for Core Bits To work efficiently, diamond core bits must maintain good diamond exposure. Many factors work together to provide the "controlled erosion" cycle of the tool's segment to occur. When this "controlled erosion" cycle is altered, the bit can become dull or "glazed." Glazing becomes noticeable when the coring feed rate slows dramatically or the bit does not cut. Examine the bit immediately. If the diamonds are flush with the metal, they are underexposed or "glazed.
MAINTENANCE WARNING To reduce the risk of injury, always unplug your tool before performing any maintenance. Never disassemble the tool or try to do any rewiring on the tool’s electrical system. Contact a MILWAUKEE service facility for ALL repairs. Maintaining Tools Keep your tool in good repair by adopting a regular maintenance program. Before use, examine the general condition of your tool. Inspect guards, switches, tool cord set and extension cord for damage.
