Operations
Note
THOROUGHLY READ THROUGH THE ENTIRE MANUAL BEFORE
OPERATING THIS MACHINE!
PURPOSE
ØThe purpose of the 8”Z1 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 vacuum 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 8”Z1 are the spindle, gearbox, motor, carriage, drill
stand and 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 travel between the drill carriage
and the drill stand. The main way to increase or decrease the users ability to move
the drill by hand is with this system. These are the black hex bolts on the side and
back of the machine that have a locking nut around them. These are generally used
to tighten up the travel as the slides wear over time. Be mindful to evenly adjust
these so that the travel is even and smooth. The ideal travel generally keeps the drill
in place when the user is not using the drill (this is usually on the tighter side)
although individual users needs may vary. The side black carriage bolt can also be
used for temporarily locking the carriage in place.

TRANSPORTING THE MACHINE
ØWhen transporting the machine, always use two hands.
ØDO NOT transport the machine with bits in the spindle.
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 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 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.
ØAfter placing the machine in work area, connect a safety chain or strap if necessary.
oThe 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.
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.
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.

8”Z1 CORE DRILL

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.
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.
