Extra shear pins are supplied with each Dymodrill and can be replaced see "Accessories" for part numbers. It is important to check the condition of the spindle before using the tool each 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.

If the motor overloads, the clutch will begin to slip and the bit will stop rotating. The clutch is factory-set and does not require adjustment. Nuisance frequent clutch slippage should be addressed by an authorized.

To reduce the risk of injury, always check the work area for hidden wires before coring. Select and install a bit following guidelines in "Selecting and Installing a Core Bit". Secure the rig to the work surface using one of the methods described in "Methods for Securing Equipment to Work Surface". With the motor OFF, adjust the gear to either high or low speed according to the guidelines in "Selecting Speeds".

To adjust the speed on all Dymodrills, move the gear shift lever to the desired setting. Connect the water hose to the Dymodrill water shut-off valve and to the water supply. Make sure the seal is watertight. Use a standard garden hose if you require additional length. Set up a water collection system. Do not continue the following steps until the vacuum gauge reads at least 20 inches of mercury vacuum.

Never operate the Dymodrill if the gauge reads less than 20 inches see "Mothods for Securing. Equipment to Work Surface". Always monitor the vacuum gauge during coring. If water collects in the vacuum pump filter jar, empty it to prevent damage to the pump. To reduce the risk of injury, do not operate the Dymorig if the gauge reads less than 20 inches of mercury vacuum.

Turn the Dymodrill motor ON. Turn the water on so it flows freely through the water shut-off valve see "Supply an Adequate Water. Turn the valve clockwise to increase water flow and counterclockwise to decrease water flow.

While holding the handle, slightly loosen the cradle lock handle and slowly rotate the handle to lower the bit into the workpiece, applying steady, even pressure.

To help reduce bit wandering, always use a light load to start the hole and wait for the tip of the bit to penetrate the work surface completely before increasing the load. Use sufficient pressure so the bit cuts constantly. Use the ammeter on the meter box as a guide for proper pressure.

NOTE: If the rig shifts during coring, stop the motor, reposition the rig and resume coring. Monitor the water flow see "Diamond Coring".

Generally, water should flow at a rate of approximately one to two gallons per minute. If the water flow is too heavy, the two holes in the water swivel housing will leak. If that happens, reduce water flow. Keep the work area dry. When the cut is complete, keep the drill motor ON and rotate the handle clockwise to remove the bit.

The bit may become stuck in the hole if you turn the motor OFF before the bit is completely removed. Once the bit is removed from the work surface, turn the motor OFF. Tighten the cradle lock handle. Unplug the meter box from the power supply before removing the vacuum pump to prevent accidental starting of the motor when the vacuum pump is released. If you are using a vacuum pump, unplug it and open the vacuum release valve to release the vacuum.

Begin coring the hole as usual. When you have cored to the length of the bit, stop the Dymodrill motor. Remove the core by driving a chisel or slender wedge into the cut between the core and the work surface.

You may also use a special core tongs, bent wire or anchor bolts to remove the core. 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.

When coring through floors, cores generally drop from the bit. To reduce the risk of injury, provide proper protection for people and property below the coring area. Core with consistent, firm feed pressure. Do not subject the bits to sudden impacts. Uneven feed rate cracks diamonds. Low feed pressure polishes diamonds, slows penetration and contributes to bit glazing. High feed pressure can overload the drill motor or can cause diamonds to pull out prematurely, particularly when coring embedded steel.

Make the bit work, but do not try to jam the bit through the material. Check for loose bolts, nuts and gib screws. Tighten if required. Check for bit runout. Replace if required. Water acts as a coolant, eliminating the heat caused by the friction of the coring action. This preserves the integrity of the diamonds, the bond matrix, the segment solder, and core tube. Without a coolant, the heat buildup during coring can cause all of these components to fail. Water flushes loose, abrasive particles created during coring.

These particles consist of aggregate, sand, diamond particles and various metals from embedded steel and the core bit matrix. The hole must be free of debris to allow the core bit to work. If loose particles are not properly flushed from the hole, an unnecessary drag will occur along the side of the core barrel.

This can contribute to bit glazing through lack of power as well as motor damage through amperage increases due to bit resistance. In addition, loose particles tend to wear the bit tube, which can eventually result in the loss of segments.

Monitor water flow. Water volume should be adjusted until water return is a muddy, solid color. Clear water or clear streaks indicate too much water volume. Excess water is a leading cause of bit glazing and failure. Other factors contribute to glazing, but water adjustment is one of the most easily controlled by the operator. When the bit segments do not properly contact the work surface, the desired "controlled erosion" effect which maintains bit sharpness does not occur and the bit begins to glaze.

This happens especially with smaller diameter bits. Adequate water volume varies according to the bit diameter. Use only enough water during coring to flush the cuttings from the work surface.

The column, carriage, motor connection and base should all be firmly connected and should not vibrate during coring. Consult motor guide in catalog. Standing on the rig's base as a form of anchoring is dangerous and does not provide the necessary rigidity.

Use light feed pressure until the bit crown has penetrated or "seated" into the material. Don't force the bit. Typically the water around the bit will clear when embedded steel is encountered. Do not allow any vibration whatsoever or severe diamond breakage or pullout will occur.

Bit binding is caused by one of two things: a dull glazed bit or a poorly stabilized rig. 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.

Examine the bit immediately. If the diamonds are flush with the metal, they are underexposed or "glazed. Reduce water flow until it becomes very muddy. Continue using as little water as possible until penetration increases. If the bit does not open up, remove from hole. Resume drilling for approximately 3 to 5 minutes with very little water and at a lower RPM if possible. Gradually increase water flow to flush sand from kerf. This abrasive material wears away the metal composition in the segment's matrix.

As this is done, sharp diamonds are exposed and the grinding action created by the diamonds continues. It does not provide the degree of abrasiveness required for matrix wear to occur and expose sharp diamonds embedded in the segment's matrix.

Glazing prevents the bit from cutting and coring. 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. Remove the motor and bit. Tip the Dymorig on its back so that the wheels point down.

Squeeze a continuous bead of rubber cement Cat. Place the new gasket Cat. 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.

Check for loose screws, misalignment, binding of moving parts, improper mounting, broken parts and any other condition that may affect its safe operation. If abnormal noise or vibration occurs, turn the tool off immediately and have the problem corrected before further use. Do not use a damaged tool. Under normal conditions, relubrication is not necessary until the motor brushes need to be replaced.

To maintain the spindle on shear pin models, remove the retaining ring with a screwdriver. Then remove the spindle sleeve. Remove dust and debris from the inside and outside diameter of the spindle and spindle sleeve and from the water hole in the spindle.

Replace the spindle sleeve onto the spindle. Make sure the spindle sleeve rotates freely on the spindle. Then replace the retaining ring.

Through normal use, the rubber gaskets on the underside of the vacuum pads can become worn, requiring replacement. If replacement is required, take the pad to an authorized service center or replace the gasket as follows:.

Remove the old gasket and thoroughly remove the old glue from the groove. Immediately place a new gasket Cat. Turn the pad over and place the gasket side on a smooth flat surface and apply pressure to all edges of the pad. Allow cement to dry for 24 hours before using. With normal use, the rubber gasket on the underside of the base can become worn, requiring replacement.

If replacement is required, take the base to an authorized service center or replace the gasket as follows:. Stand the Dymorig upright again. Reinstall the motor and bit. Periodically clean the filter felts to keep the vacuum pump operating efficiently.

To clean the filter felts, remove the plastic jar and remove the felts from the plastic tube. Remove dust and debris from the felts and clean the plastic jar.

Then replace the felts on the plastic tube and position the jar onto the filter assembly. To reduce the risk of injury, electric shock and damage to the tool, never immerse your tool in liquid or allow a liquid to flow inside the tool.
