Operations
Note
THOROUGHLY READ THROUGH THE ENTIRE MANUAL BEFORE
OPERATING THIS MACHINE!
PURPOSE
ØThe purpose of the 12”Z1 LRB/TS Core Drill is to drill through masonry, concrete or other mineral rock
types using annular coring bits.
ØThese drills are designed to be bolted to the drilling surface through their base.
oNOTE: Make sure the base fits completely on the surface and the base is securely fastened using
wedge anchors to bolt to the surface.
ØThese 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.
oCAUTION: 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
ØThe 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.
ØThese drills are ONLY to be used with diamond impregnated coring bits.
oWhen drilling with “wet” type bits, the bit ends pulverizes the material and the water brings the
material out of the cut.
oWhen drilling with “dry” type bits, the bit end pulverizes the material and dust brings the material
out of the cut.
MACHINE COMPONENTS
ØThe 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.
oThese components must be not be removed except by a qualified technician. Power must be
disconnected prior to any service.

ØThis machine has one primary adjusting point for the angle between the drill stand and the drill motor. The
angle Adjusting bolt (12 below) can be loosened to adjust the angle and retightened when desired angle is
achieved. NOTE: The drill carriage can also be locked in place by twisting until the locking bolt engages
towards the carriage. To unlock the carriage pull out the bolt and turn.
TRANSPORTING THE MACHINE
ØWhen transporting the machine, always lock the carriage bolt.
ØAlways carry the machine with both hands.
ØDO NOT transport the machine with bits in the spindle.
ØWhen 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.
oAvoid dragging the vacuum rubber. You can take the rubber out if not using.
ØIf transporting inside a vehicle, it is recommended to transport it on its side so as to avoid the item falling
over.
ØDO NOT carry/pull the machine by the cord.
ØDO NOT allow the cord or plug to drag along the floor when transporting.

RUNNING THE MACHINE
ØDo all pre-operational and operational safety checks from Chapter 1.
ØConsider your security and stability as well as the orientation of the machine in the work area.
oConsider the work surface material, condition, strength, density and rigidity. These factors
directly affect the tools efficiency.
ØSecure the machine base to the work surface by using a wedge anchor, vacuum system or other method to
ensure the base does not move.
ØUse the four leveling bolts on the corners of the base to level the machine if needed.
oIf 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.
ØAfter placing the machine in work area, connect a safety chain or strap if necessary.
oA 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.
ØIf necessary, adjust drilling angle.
oLoosen the lower side bottom bolt on the base as necessary.
oAdjust the angle and tighten the side bolt
ØEnsure the feed handles are securely attached to the feed spindle.
ØEnsure the work surface is free of debris, oil, etc.
ØSelect and set up fluid delivery method or dust system.
ØSelect the gear you will be using.
oDo not force the gear shifter when changing between gears. There is a neutral position between
gear 1 and gear 2.
oChange gears when the machine is stopped or almost stopped.
ØIf using the machine horizontally with the water system, connect hose to the side of the machine using the
connector.
oThis connector takes standard ¾” US garden hose hookup.
oMake sure the water valve is in the off position.
§This is generally at a 90 degree angle from the valve hose.
oPartially 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.
ØSelect appropriate size cutting bit. See section below for details on securing bit.
ØCheck that the machine is firmly attached to the work area.
ØPlug the machine into power source.
oForm 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.
ØTurn feed handle raising the cutter until the bit is above the work surface.

12”Z1/TS CORE DRILL

ØOpen the water valve to allow water to come out to the work surface.
ØATTENTION: 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.
ØTurn the machine on by flipping the breaker switch to the “on” position.
ØVery slowly engage the cutting bit with the material surface by lightly engaging the hand crank down
towards the material.
oNOTE: During the initial stages of contact the bit may wander.
ØAfter 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.
oNOTE: 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.
oIf 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.
ØMake sure to keep the cutting material lubricated.
ØEase up on feed pressure as the cutter starts breaking through the backside of the material.
oBe certain all is clear on the output side of this core to prevent injury to persons or property.
ØFinish drilling the hole.
ØTurn the motor off and disconnect power once the drill is safely back up in the non-drilling position.
ØTurn water valve off.
ØUnbolt the wedge anchor.
ØDisconnect safety chain/strap and move the drill to a new drilling location.
INSTALLING CORING BITS
ØWARNING: Core bits can be sharp and should only be handled with gloves so as not to cut the user during
installation or removal.
ØCheck that the bits are not damaged.
oCoring bits that are damaged should not be used.
ØMake certain the machine is unplugged from power.
ØRaise the drill motor to ensure ample room to install the bit.
oApply grease to the spindle thread to prevent corrosion and allow easier core bit removal.
ØInsert the coring bit and screw it onto the drill spindle.
ØTighten the bit until fully tightened.
oUse wrenches that fit the spindle and coring bit to fully tighten.

General Maintenance
ØInspect electrical cords and electrical connections.
ØKeep machine clean and free of debris.
ØCheck for misalignment, binding and breakage of all moving parts. If damaged, repair tool before use.
ØKeep cutting tools sharp and clean. Sharp bits are less likely to bind and are easier to control.
Occasional Maintenance
ØHave the power tool serviced by a qualified service technician using identical replacement parts.
oChange motor brushes:
1) Disconnect drill from power.
2) Unscrew left and right side brush holder caps using a flathead screw driver.
3) Take out old brushes.
oIf you need to, use the screw driver to nudge them out.
4) Replace with exact same size new brushes.
5) Screw in brush holder caps tightly.
oAdjusting Carriage:
1) Periodically check and adjust slides as necessary.
2) Use hex wrench to loosen the hex bolts on the carriage. There are four hex bolts on
each adjusting slide. Backing out the bolts will loosen feed tension, while tightening
the bolts will increase feed tension.
3) Adjust the bolts evenly while moving the handle up and down so that there’s no free
play yet not binding anywhere through its range of travel.
oChange Gear Oil:
1) Change if necessary using NLGL-2 grade grease. This service is generally done around
the 50 hour service mark.
oAdjust Safety Clutch:
1) Adjust clutch as necessary.
