Operations

Note

THOROUGHLY READ THROUGH THE ENTIRE MANUAL BEFORE

OPERATING THIS MACHINE!

Chapter 3

PURPOSE

Ø The purpose of the 12”Z1 LRB/TS Core Drill is to drill through masonry, concrete or other mineral rock types using annular coring bits.

Ø These drills are designed to be bolted to the drilling surface through their base. o NOTE: Make sure the base fits completely on the surface and the base is securely fastened using wedge anchors to bolt to the surface.

Ø These machines can be used vertically, horizontally or overhead (inverted) provided an acceptable work environment. NOTE: For safety, when drilling horizontally or overhead a safety chain/strap should always be used. o CAUTION: If drilling overhead you are only permitted to use dry type core bits with a dust collection system. “Wet” type holes overhead would allow water into the motor and create an extremely dangerous situation.

OPERATIONAL PRINCIPLES

Ø The main drilling shaft rotates in a forward clockwise direction. The main drilling motor connects to the tool spindle to make contact with a surface and slowly bore a hole. Using the feed handles on the side of the drill, the user can raise or lower the drilling motor.

Ø These drills are ONLY to be used with diamond impregnated coring bits. o When drilling with “wet” type bits, the bit ends pulverizes the material and the water brings the material out of the cut. o When drilling with “dry” type bits, the bit end pulverizes the material and dust brings the material out of the cut.

MACHINE COMPONENTS

Ø The main components of the 12”Z1 LRB/TS are the spindle, gearbox, motor, carriage, drill stand and wheeled base. The spindle is driven by the transfer case and the motor. o These components must be not be removed except by a qualified technician. Power must be disconnected prior to any service.

Ø Always carry the machine with both hands.

Ø DO NOT transport the machine with bits in the spindle.

Ø When using the wheels, tilt the machine back towards the operator and once the wheels are engaged with the ground pull or push the machine on the ground. o Avoid dragging the vacuum rubber. You can take the rubber out if not using.

Ø If transporting inside a vehicle, it is recommended to transport it on its side so as to avoid the item falling over.

Ø DO NOT carry/pull the machine by the cord.

Ø DO NOT allow the cord or plug to drag along the floor when transporting.

1 2 ” Z 1 L R B / T S C O R E D R I L L

RUNNING THE MACHINE

Ø Do all pre-operational and operational safety checks from Chapter 1.

Ø Consider your security and stability as well as the orientation of the machine in the work area. o Consider the work surface material, condition, strength, density and rigidity. These factors directly affect the tools efficiency.

Ø Secure the machine base to the work surface by using a wedge anchor, vacuum system or other method to ensure the base does not move.

Ø Use the four leveling bolts on the corners of the base to level the machine if needed. o If not using the vacuum base, you can either take out the vacuum foam or adjust the leveling bolts down ½” past the foam. It is generally recommended to take the foam out when not using as it can cause tears in the foam material transporting and moving the machine.

Ø After placing the machine in work area, connect a safety chain or strap if necessary. o A safety chain should attach to the machine (preferably through the carrying handle or O bolt) as well as attached to the work area in such a manner that prevents the machine from detaching or falling from the work area.

Ø If necessary, adjust drilling angle. o Loosen the lower side bottom bolt on the base as necessary. o Adjust the angle and tighten the side bolt

Ø Ensure the feed handles are securely attached to the feed spindle.

Ø Ensure the work surface is free of debris, oil, etc.

Ø Select and set up fluid delivery method or dust system.

Ø Select the gear you will be using. o Do not force the gear shifter when changing between gears. There is a neutral position between gear 1 and gear 2. o Change gears when the machine is stopped or almost stopped.

Ø If using the machine horizontally with the water system, connect hose to the side of the machine using the connector. o This connector takes standard ¾” US garden hose hookup. o Make sure the water valve is in the off position.

§ This is generally at a 90 degree angle from the valve hose. o Partially turn the water spigot on (usually half a turn).

§ CAUTION: DO NOT turn the hose on fully! You need sufficient water when using wet type bits. Using too much water pressure can cause the bits to not cut properly as well as water entering the gearbox.

Ø Select appropriate size cutting bit. See section below for details on securing bit.

Ø Check that the machine is firmly attached to the work area.

Ø Plug the machine into power source. o Form a loose knot in the power cord close to the plug connection to prevent fluid from running down the cord and into the power receptacle.

Ø Turn feed handle raising the cutter until the bit is above the work surface.

8

1 2 ” Z 1 L R B / T S C O R E D R I L L

Ø Open the water valve to allow water to come out to the work surface.

Ø ATTENTION: BE AWARE THESE MACHINES ARE EXTREMELY POWERFUL. THEY HAVE A TREMENDOUS

AMOUNT OF TORQUE, WHICH MIGHT NOT BE SUITABLE FOR ALL POTENTIAL USERS. ESPECIALLY IN

LOW GEAR AND WITH LARGER BITS. DESPITE THE SAFETY CLUTCH, THESE DRILLS CAN STILL

INJURE THE USER. IF IN DOUBT, CONTACT A PROFESSIONAL FOR ADVICE.

Ø Turn the machine on by flipping the breaker switch to the “on” position.

Ø Very slowly engage the cutting bit with the material surface by lightly engaging the hand crank down towards the material. o NOTE: During the initial stages of contact the bit may wander.

Ø After about 1/8” of cutting has been achieved in the work surface, slightly more force can be applied. This will be the normal amount of force the rest of the hole. o NOTE: Do not force the hole. Let the machine do most of the work. Excessive physical effort should be avoided as it can cause damage to the machine or the user. o If the unit jams in a hole, stop the drill immediately to prevent injury. Disconnect the drill from the power supply and loosen the cutter by turning drill spindle counterclockwise. Never attempt to free bit by starting motor!

§ After an interruption in drilling, make sure the drill bit is free and turns before restarting the hole. Be very careful at this point to make certain the drill does not bind when restarting.

Ø Make sure to keep the cutting material lubricated.

Ø Ease up on feed pressure as the cutter starts breaking through the backside of the material. o Be certain all is clear on the output side of this core to prevent injury to persons or property.

Ø Finish drilling the hole.

Ø Turn the motor off and disconnect power once the drill is safely back up in the non-drilling position.

Ø Turn water valve off.

Ø Unbolt the wedge anchor.

Ø Disconnect safety chain/strap and move the drill to a new drilling location.

INSTALLING CORING BITS

Ø WARNING: Core bits can be sharp and should only be handled with gloves so as not to cut the user during installation or removal.

Ø Check that the bits are not damaged. o Coring bits that are damaged should not be used.

Ø Make certain the machine is unplugged from power.

Ø Raise the drill motor to ensure ample room to install the bit. o Apply grease to the spindle thread to prevent corrosion and allow easier core bit removal.

Ø Insert the coring bit and screw it onto the drill spindle.

Ø Tighten the bit until fully tightened. o Use wrenches that fit the spindle and coring bit to fully tighten.
