• Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorised service providers.

SPECIFIC SAFETY RULES FOR CORING EQUIPMENT

• When performing drilling that requires the use of water, route the water away from the operator’s work area or use a liquid collection device. Such precautionary measures keep the operator’s work area dry and reduce the risk of electrical shock.
• Operate power tool by insulated grasping surfaces, when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock
• Wear hearing protection when diamond drilling. Exposure to noise can cause hearina loss.
• When the bit is jammed, stop applying downward pressure and turn off the tool. Investigate and take corrective actions to eliminate the cause of the bit jamming.
• When restarting a diamond drill in the workpiece check that the bit rotates freely before starting. If the bit is jammed, it may not start, may overload the tool, or may cause the diamond drill to release from the workpiece.
• When securing the drill stand with anchors and fasteners to the workpiece, ensure that the an- choring used is capable of holding and restraining the machine during use. If the workpiece is weak or porous, the anchor may pull out causing the drill stand to release from the workpiece.
• When securing the drill stand with a vacuum pad to the workpiece, install the pad on a smooth, clean, non-porous surtace. Do not secure to laminated surfaces such as tiles and composite coating. If the workpiece is not smooth, flat or well affixed, the pad may pull away from the workpiece.
• Ensure there is sufficient vacuum before and during drilling. If the vacuum is insufficient, the pad may release from the workpiece.
• Never perform drilling with the machine secured by the vacuum pad only, except when drilling downwards. If the vacuum is lost, the pad will release from the workpiece.
• When drilling through walls or ceilings, ensure to protect persons and the work area on the other side. The bit may extend through the hole or the core may fall out on the other side.
• Never use this product for overhead drilling.
• Always use expansion-type anchor to hold stand on cracked, uneven, porous, or vertical surfaces.
• Do not operate tool with carrier above line marked on mast. Tool and stand could become unsecure and tip over during use causing serious injury.
• Chemical Burn Hazard. Keep coin cell battery awav from children.

WARNING Applications, risk produce in considerable amount of dust, use a suitable dust extraction solution in accordance with the solution’s operating instructions.

• Always use common sense and be cautious when using tools. It is not possible to anticipate every situation that could result in a dangerous outcome. Do not use this tool if you do not understand these operating instructions or you MIL WAUKEE iS lord Trained professional tot additional information or training.
• Maintain labels and nameplates. These carry important information. If unreadable or missing, contact a MILWAUKEE® service facility for a replacement.

The following contin core greatly influence diamond core performance:

• Amount of water
• RPM of core drill motor
• Bit run out
• Amount of steel
• Size of embedded steel
• Age of concrete
• Aggregate (size, type, hardness, abrasiveness)
• Type of sand–manufactured vs. river (natural)
• Operator technique
• Operator care
• Feed pressure applied to bit by operator
• Core Drill Stand rigidity and condition

To extend core bit life:

• Choose the right bit for the job. Take into account the size, aggregate, sand, etc.
• When using a new bit, use light feed pressure for breaks in.
• Feed bits very slowly onto the work surface. Use light feed pressure until the bit crown has penetrated or “seated” into the material.
• If the core bit encounters embedded steel, slow down the feed pressure and let the bit core at its own pace. Don’t force the bit. Typically, the water around the bit will clear when embedded steel is encountered.
• Minimise all vibration. Slow the feed rate when necessary. Vibration will cause severe diamond breakage or pullout.
• Use sharp bits.

WARNING To reduce the risk of injuryworking in dusty situations, wear , when appropriate respiratory protection or use a suitable dust extraction solution.
When drilling with water, route the water away from the work area or use a liquid collection device to keep work area dry and reduce the risk of electrical shock. Do not allow water to flow inside machine or battery pack.

Water provides several benefits during coring

• Water acts as a coolant, reducing the heat caused by the friction of the coring action. This helps to preserve 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. Water helps to keep dust down and makes for a cleaner, healthier workplace.

WARNINGAlways use a suitable dust extraction solution.
To prevent visible dust, an adequate supply of water must flow freely and constantly during the entire cut. A built-in water system allows water to flow down the inside and up around the outside of the bit.

WARNINGAlways use a suitable dust extraction solution.

WARNING When drilling with water, route the water away from the work area or use a liquid collection device to keep work area dry and reduce the risk of electrical shock.

1. Use clean water at less than 90 psi through the hose attachment when operating.
2. Fasten a standard 16 mm (5/8″) quick-connect fitting to the end of a 16 mm (5/8″) hose, and connect the hose to the drill.
3. Do not use hoses that are distorted, worn or damaged.
4. Use the water valve to turn the water supply on and off when coring.

Clutch Servicing
The MX FUEL™ Super Core Drill has a mechanical clutch; it is usual to hear sounds and feel vibrations from the Drill. If the clutch activates regularly during normal operation within the green load lights “Ideal Pressure”, the clutch needs to be serviced. Return the Drill to the nearest authorised MILWAUKEE® service centre.
NOTE: AVOID activating the clutch for more than 10 seconds at a time. The clutch being active for long periods of time could cause damage to the clutch, and drill resulting in a loss of performance.

Selecting Gears
Select the gear according to the bit diameter and base material. Only change gears when the machine is stopped. Press in the button on the side of the gear selector, and then turn the gear selector until it latches completely into the appropriate gear for the application.

Arming the Machine
The MX FUEL™ machines must be armed prior to use. Even with the battery pack inserted, the trig-ger and machine functions will not operate until the machine is armed.
To arm the machine:

1. Insert the battery pack.
Press the Arm button. The MX FUEL™ icon will light. The spindle switch will become armed in 2 seconds.
After 15 minutes of inactivity, the machine will enter sleep mode. The MX FUEL™ icon will go off and the Spindle Rotation ON/OFF switch and LEDs are unoperational.
Press and hold the Arm button for 1 second to reactivate the machine.
Press and hold the ARM button for 1 second to unarm (turn off) the machine. The MX FUEL™ icon will go off.

Hole Start Mode
Use the Hole Start Mode to help avoid bit jamming or bit binding when starting a hole. Hole Start Mode will run until the bit is “seated” into the material, then it
in the selected gear.

Activating the Hole Start Mode

1. With the machine armed, turn on the spindle by switching to the ON position.
2. Press the button, to start the Hole Start mode.

Deactivating the Hole Start Mode:

1. To turn off the machine, press to the OFF position.
2. Unarm the machine.

Digital Level

• Use the digital level to ensure the hole is level throughout the operation. Use the digital level to properly align the core drill when installing into a core drill stand. The four red arrow LEDs indicate where the machine is not level and the direction in which the machine needs to be moved to become level. Check eyebolts, vacuum pad, and anchor when leveling. The centre white LED indicates the machine is level.
• When level, the centre White LED will light up (<1.5° off of level).
• When “slightly” off level (1.5° – 2.7°), the centre White LED and the Red LED associated with the direction that is off centre will illuminate.
• When “very” off level, the red LED will show the direction out of level and will illuminate (>2.7° out of level).

NOTE: The digital level will flash four red arrow LEDs and a white centre LED in an alternating pattern if the machine is unable to provide a level. If this occurs, the machine will still operate upon normal cycling of the switch. In order to restart the digital level, the machine will need to be disarmed and re-armed again. If the machine still does not work properly, return the machine, charger and battery pack, to a MILWAUKEE® service facility for repairs.

Performance Indicator

The performance indicator provides pressure feedback. The LEDs will light up one by one as pressure is applied to the bit. Increase or decrease pressure on the bit to reach the green “Ideal Pressure”. When using new diamond bits, follow manufacturer’s instructions for breaking them in (see “Diamond Core Bits”).

After the bits have been -RED-broken in, low feed pressure  will polish diamonds, slows re penetration and contributes to bit glazing. High feed pressure can overload the core 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.

Core Drilling Procedure

WARNING To reduce the risk of injury, do not core unless the proper vacuum has been achieved when the stand is secured with a vacuum system. Do not rely on the weight of the stand, shoring pin alone, or body weight on the stand for securing during use. The stand will rotate and cause injury.

1. Secure the stand to the work surface using expansion-type anchors or vacuum pad system.
   WARNING Do not rely on the weight of the stand, shoring pin alone, or body weight on the stand for securing during use. The stand will rotate and cause injury.

2. Install the core drill onto the stand according to the core drill stand instructions (see “Mounting the Core Drill to the Stand”).

3. When securing with a vacuum, set up the vacuum system according to the vacuum manufacturer’s instructions.
   WARNING Do not core unless the proper vacuum has been achieved. Always monitor the vacuum gauge while coring.

4. When securing with an expansion-type anchor, ensure the nut is securely tightened against the anchor plate before coring.

5. Install the bit according to “Selecting and Installing a Core Bit” section.

6. Select the gear according to “Selecting Gears” section.

7. Insert the battery pack.

8. Press the Arm button.

9. Use the digital level to ensure the core drill is plumb before and during the coring process. If the core drill is not plumb, stop coring and re-level the machine.

10. Ensure water source is connected properly of water to the bit by opening the water valve. WARNING When drilling with water, route the water away from the work area or use a liquid collection device to keep work area dry and reduce the risk of electrical shock.

11. Turn on Hole Start Mode.

12. To start the machine, switch to the ON position.

13. Use light feed pressure until the bit crown has penetrated or “seated” into the material. Once seated, hole start mode will turn off. Continue with the selected gear for the remainder of the coring process.

14. Once the bit is “seated”, use the Performance Indicator to determine if proper pressure is being used throughout the cut. Increase or decrease pressure as needed.

15. Monitor the water flow. Adjust the water valve so the water return is a muddy, solid colour. Clear water or clear streaks indicate too much water volume.

16. When the cut is complete, raise the bit from the cut slowly using the feed handle.

17. To stop the machine, switch to the OFF position. Make sure the bit comes to a complete stop.

18. Close the water valve.

19. Press the arm button to turn OFF the machine.

Retrieving Cores and Deep Coring

When coring holes that are deeper than the core bit:

1. Core the hole. Once the maximum depth has been cut, remove the bit from the hole and stop the machine.
2. Remove the core by driving a chisel or slender wedge into the cut between the core and the work surface. Other items, such as core tongs, bent wire or anchor bolts can also be used to remove the core. Removing cores with diameters greater than remove the pieces.
3. Reinstall the bit using a bit extension, if necessary, and continue coring.

Troubleshooting

Vibration

1. Stop drilling.
2. Turn core drill off.
3. Remove battery.
4. If the carrier is loose, see “Adjusting Carrier As-sembly” in the maintenance section.
5. Check for excessive bit runout. Replace if required. If vibration continues to occur, remove the core and loose material. If vibration continues to occur after attempting these measures, return the rig to the nearest MILWAUKEE® service facility.

Bit Binding
Bit binding can occur by a dull “glazed” bit, a poorly stabilised stand, or particles within a cut.

Causes of bit glazing

• Wrong RPM for bit diameter
• High feed pressure
• Low feed pressure
• High steel content in work surface
• Large, hard aggregate
• Too little water
• Low motor power

Transporting

1. Remove the battery, and spare battery from the storage holder on the stand.
2. Remove the machine from the stand.
3. Ensure the machine, stand, and batteries are secure before transporting.

   • Loosen the outer nut slightly.
   • Hand-tighten the shaft with a flat screwdriver to 0.11 – 0.56 nm (1 – 5 in-lb).
   • Manually tighten the outer nut.

NOTE: Over-tightening the assembly will make the carrier difficult to move up and down.

Lubricating Rack

Maintain a light coat of grease on the rack to reduce friction and wear when the carrier is moved up and down

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 ma- chine’s segment to occur. When this “controlled erosion” cycle is altered, the bit can become dull or “glazed”. Glazing becomes noticeable when the cor- ing teed 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”. The following steps will often correct the problem:

1. Reduce water flow until water becomes very muddy. Continue using as little water as possible until penetration increases.
2. Into be denia to (na rayer of frica hole. poue coarser the better).
3. Resume drilling for approximately 3 to 5 minutes with very little water and at a lower RPM.

Maintaining Machine
Keep your machine, battery pack and charger in good repair by adopting a regular maintenance program. Inspect your machine for issues such as undue noise, misalignment or binding of moving parts, breakage of parts, or any other condition that may affect the machine operation. Return the machine, battery pack, and charger to a MILWAUKEE® service facility for repair. If the machine does not start or operate at full power with a fully charged battery pack, clean the contacts on the battery pack. If the machine still does not work properly, return the machine, charger and battery pack, to a MILWAUKEE® service facility for repairs.
