I PREPARATION

A. Safety Precautions

IMPORTANT

! THE FOLLOWING SAFETY PRECAUTIONS MUST BE OBSERVED

.

1. Know your core drilling machine! Read the Operator’s manual carefully. Learn the operation, application and limitations, as well as the specific potential hazards peculiar to this equipment.

2. Ground the machine! The core drill must be grounded while in use to protect the operator from electric shock. The motor is equipped with a three prong grounding type plug to fit the proper type receptacle. The green [or green & yellow] conductor in the cord is grounding wire.

3. NEVER connect the green [or green & yellow] wire to a live terminal.

4. Use only three-wire grounded extension cords suitable for use outdoors and of sufficient gage to accommodate power requirements.

5. Replace frayed or damaged extension cords.

6. Keep the work area clean avoiding cluttered work areas.

7. Consider the work area environment!

¾ Do not expose power tools to rain.

¾ Wear rubber boots to further insulate yourself from the drill.

¾ Mop up all excessive water around the work area before and after drilling.

¾ Keep the work area well lit.

8. Use extreme caution when drilling through floors. Provide for protection of all personnel and material below the area. Cores generally drop from the drill bit at the completion of the hole.

9. Keep visitors away. Do not let visitors contact tool or extension cord. All visitors should be kept at a safe distance from the work area.

10. Do not force the bit into the drilling surface.

¾ Use an anchor bolt , ceiling jack or vacuum hold-down attachment when drilling vertically

( ÐÏ) into floors.

¾ Only use an anchor bolt or ceiling jack when drilling horizontally (ÕÖ) into a wall or any other vertical surface.

11. Dress properly for the work being performed.

¾ Do not wear loose clothing or jewelry which can get caught in moving or rotating parts.

¾ Rubber gloves and non-skid footwear is recommended when working outside.

¾ Wear protective covering to contain long hair.

12. Don’t abuse the cord. Never carry the tool by the cord or yank the cord to disconnect the plug from the receptacle.

13. Secure the drill stand to the work surface. Use an anchor bolt, ceiling jack or vacuum attachment to secure the drill stand to the work surface.

14. NEVER stand on the drill stand base as a method of securing the drill stand!

15. Don’t overreach! Keep proper footing and balance at all times. The slippery surface created during the drilling operation results in unstable footing.

16. ALWAYS disconnect the power before servicing or changing accessories or bits.

17. ALWAYS check, then make sure wrenches are removed from the motor spindle and bit adapter before connecting power or starting the drill motor.

18. ALWAYS make sure power switch is in “off” position before connecting drill to power.

Caution: It is very important that the drilling machine is properly secured to the work surface. Movement during drilling will cause bit chatter against work surface, fracturing diamonds or binding bit in the hole.

I PREPARATION

B. General Information

The Dr520 & Dr620 core drills are available with different power units.

MANUFACTURER AMPS VOLTS PHASE HERTZ

60

60

60

All motors are single phase with two-speed selector switches. The 115 volt motors will operate within a power range of 110 to 120 volts.

C. Bit Installation

The threads on the output spindle of the core drill motors have dimensions of 1-1/4"-7.

Core bits are available in a variety of diameters. The spindle thread on the adapter nut of the core bit is 5/8-11 on smaller diameter bits. The use of an adapter coupling part number 400148 is required in order to run smaller diameter bits. The adapter provides a coupling which has a female 1-1/4"-7 thread on one side and a 5/8"-11 spindle on the other end.

Core Bit Adapter

Part Number 400148

1. Using a wrench to firmly hold the output shaft , screw the core bit onto the spindle until snug.

2. Placing one wrench on the machined flats of the output shaft and one wrench on the end adapter of the core bit tighten the bit on the spindle. Note: Attempting to turn the bit by the barrel rather than by the adapter nut may break the weld between the adapter nut plate and the barrel.

D. Water Supply

It is important when wet cutting to maintain an adequate supply of clean water to the diamond drill bits. The hose input adapter on the water swivel at the base of the core drill motor is used to connect the water supply hose to the core drilling unit. Special precautions should be taken to insure that the water supply will not be interrupted during the drilling operation.

The DR520 & DR620 core drills are manufactured with a three conductor connector cord which attaches the motor to the electrical supply. The green wire provided is used to connect to a permanent ground. z a. Before connecting the drill to the power source, make sure that the voltage and cycles shown on the name plate of the motor are the same as the available electrical power supplied. z b. Always properly ground the core drill before attempting to start the motor. The presence of water during the drilling operation requires that the drill always be properly grounded. z c. NEVER connect the green wire to a live terminal

!

The use of 3-prong adapter is prohibited in Canada by the Canadian Electrical Code.

An adapter, Fig. "B" is available for connecting Fig.

A plugs to two prong receptacles. The green grounding ear extending from adapter must be connected to a permanent ground such as to properly grounded outlet box. No adapter is available for fig "C" plugs.

To connect twist lock plugs like those shown in figures D and E, insert the plug into a matching outlet. When the plug is fully inserted, turn it clockwise until it locks. This prevents the plug from being pulled out accidentally. To remove the plug, twist it counterclockwise to unlock it and remove it from the outlet.

II OPERATION

A. Core Drill Positions

To position the core drill:

1. Roll the drill so that the spindle is positioned over the desired drilling location.

2. Using the leveling screws located on the four corners of the base, level the core drill to insure that the bit will drill a straight, vertical hole.

ÖCEILING BRACING - can be used when the ceiling above the work area is strong enough to provide solid bracing. A length of pipe may be used with the adjustable brace on the top of the drill column to firmly secure the drill against the work piece.

ÖANCHOR BOLTING - is a method used quite often in both horizontal and vertical drilling.

The anchor is secured in the work surface and the core drill is placed over the anchor bolt so that the bolt goes through the hole in the center of the drill base. A nut and washer is the used to pull the base down as the nut is screwed onto the anchor bolt.

ÖVACUUM HOLD DOWN - requires that the surface of the intended drilling area be smooth or of an even texture in order to achieve an effective bond to the drilling surface.

A large hold down base and vacuum pump are used to fasten the drill to the work surface. Both the pump and large base are available as optional accessories for the drills.

B. Drilling Technique

The performance of any diamond core bit depends heavily on the use of proper drilling technique. Although drilling conditions and materials may vary, following specific guide lines insures faster drilling speeds and longer bit life.

1. Secure the core drill to the work surface so that there is no movement in the drill that would cause the core bit to bind in the hole.

2. Insure that the hole is constantly flushed

Vacuum Pump Attachment

PART NUMBER: 407000 of abrasive fines by supplying a sufficient flow of water.

3. Slowly lower the bit into the hole so that there is no skidding or lateral movement of the drill. The entire circumference of the core bit should penetrate the drilling surface before additional pressure is applied to the handle.

4. Exert steady downward pressure while drilling. NEVER force the bit into the material!

5. Do not stop the flow of water or rotation of the bit while the core bit is drilling.

6. Check the core bit if the drilling rate decreases noticeably. The slowing penetration rate generally indicates that the bit is in need of reconditioning.

II OPERATION

C. Vacuum Hold Down Operation

The vacuum hold down base and pump work together to seal the drill to the work surface.

The vacuum pump requires 115 volt electrical supply. A 115 volt accessory outlet located on the switch box is used to supply power to the vacuum pump. One outlet is consistently supplied with power so that turning the motor off does not turn off the vacuum pump and release the drill from the work surface.

1. Mount the column and carriage in the large vacuum hold down base.

2. Connect the vacuum pump to the vacuum base.

3. Wet the work area in order to achieve an effective seal.

4. Connect the vacuum pump cord into the top outlet of the receptacle in the switch box above the motor. This will start the pump and create a seal between the base and the work surface.

5. Adjust the leveling screws so that the core drill is level and resting lightly on the vacuum seal.

6. Plug the vacuum pump cord into the live outlet of the receptacle in the switch box. This will start the pump and create a seal between the base and the work surface.

7. Adjust the leveling screws so that the base is snug against the work surface. NOTE:

(Excessive tightening of the leveling screws will break the seal between the base and the work surface).

8. To turn the vacuum pump off, unplug the power cord.

D. Water Collector Operation

The water collector unit (Part Number 402034) is designed to work with any core drill. It can be used with any diameter core bit up to and including ten inch. The unit consists of a tear dropped shaped ring with a rubber seal, a 115 volt electric water pump and a drainage hose.

1. Place the pump in the small end of the tear-drop ring. Center the large area of the ring over the area to be drilled.

2. Run the drainage hose from the pump to a drainage barrel and secure the hose to the barrel with the hose hook.

3. PROPERLY GROUND THE PUMP, then plug it into the top outlet of the core drill switch box.

4. Turn the pump off by unplugging the pump power cord at the cord drill switch box.

*Refer to motor owners manual supplied with drill for required motor maintenance.

The Cardi motor is designed to operate at two speeds. Changing speeds is accomplished by using the speed shift knob built into the gear case of the unit.

Changing the rpm of the motor is accomplished as follows:

1. Turn off switch, wait for spindle to stop then rotate the shift knob to go from the

HIGH(••) to LOW(•) speed.

2. Move the shift knob until the clutch teeth are fully engaged. Moving the knob toward the single dot engages the LOW rpm while moving the knob toward the two dots engages the HIGH rpm.

3. Attempting to shift with the motor off may require turning the spindle by hand to engage the clutch.

Changing the rpm while the motor is running will damge gears and void warranty.

III. MAINTENANCE AND COMPONENT DESCRIPTION

The vacuum pump is used with the large vacuum hold down base to secure the core drill on smooth evenly textured surfaces. The pump is powered by a 115 volt, 4.2 amp, 60 hertz electric motor. The power cord of the pump is plugged into the live outlet of the receptacle in the switch box of the core drill. The

OPTIONAL

GAST VACUUM PUMP

COMBINATION BASE switch box on the drill allows the motor on the drilling unit to be turned on and off without shutting down the vacuum pump and breaking the seal between the drill base and the work surface.

The required maintenance procedure for the vacuum pump is listed in the "Parts List and

Operating and Maintenance Instructions" pamphlet. Parts for the vacuum pump are available from local distributors of Gast products. A listing of Gast distributors is available in this drill manual and in the vacuum pump pamphlet.

B. Leveling Screws

The four leveling screws on the base should cleaned with a mild solvent and lubricated with a lightweight machine oil each time the machine is used. Allowing the slurry to accumulate on the threads may cause damage to the threads in the base.

C. Carriage

The carriage or head assembly should be cleaned and lubed with a lightweight machine oil each time the machine is put away. Allowing slurry to build on the column and inside the carriage will prematurely wear the pinion gear and gibs.

11

III. MAINTENANCE AND COMPONENT DESCRIPTION

D. Gibs

The gibs are brass wear shims used on the inside of the carriage which allow the carriage to slide freely and rigidly on the column. The gibs require periodic replacement. Replacing the gibs is necessary when the carriage is no longer rigid on the column. Keeping the column free of excess debris and burrs will maximize the service life of the gibs.

E. Motor Spindle

The motor spindle on all core drill motors is equipped with 1-1/4"-7 thread dimensions. The end adapter of the core bit is also threaded 1-1/4"-7 on core bits of 2 inches and larger diameter. Core bits with a diameter less than 1-5/8 inches have 5/8”-11 threads and require the use of an adapter.

The motor spindle maintenance should be performed each time the machine is stored for the day. Leaving the core bit on the motor spindle may cause the threads on the spindle to rust making removal of the core bit very difficult. After removing the core bit check the threads for any nicks or burrs. The spindle should then be cleaned with a mild solvent and lubricated with a lightweight machine oil.

Removing the core bit from the motor spindle by turning the core bit barrel is not recommended. The core bit barrel may break the weld between the adapter plate and barrel if excessive side pressure is applied. The best results are achieved using two wrenches. One of the wrenches placed on the machined flats on the motor spindle and the other wrench on the core bit end adapter.

F. Vacuum Seal

The vacuum seal is the sponge rubber gasket which lines the bottom of the large vacuum base. The material prevents air from entering the area under the base. Thus allowing the vacuum to pull against the work surface. In order for the seal to work properly the seal material must remain pliable and in one piece with no gaps or inconsistencies on the surface. The vacuum seal should be rinsed at the completion of each operation. Allowing the slurry to accumulate on the gasket will cause the material to deteriorate prematurely. The vacuum seal should be checked on a regular basis and replaced if it has been damaged or started to deteriorate.
