5) OPERATIONAL SAFETY PROCEDURES
READ BEFORE USING THE MACHINE
▪When using electrical tools, basic safety precautions should always be followed to reduce the risk of electric shock, fire
and personal injury.
▪Ensure the magnet is off before plugging in the machine.
▪Do not use in wet or damp conditions. Failure to do so may result in personal injury.
▪Do not use in the presence of flammable liquids, gases or in high risk environments. Failure to do so may result in
personal injury.
▪Before activating the machine, inspect all electrical supply cables (including extension leads) and replace if damaged. Do
not use if there are any signs of damage.
▪Only use extension cables approved for site conditions.
▪Before activating the machine, always check the correct function of all operational systems, switches, magnet etc.
▪Before operating, the machine must be securely restrained to a fixed independent feature by using safety strap RDC4083
and stationary rings RDC4082.Affix the stationary rings into the magnet, uppermost side hole to reduce the potential free
movement. Should the magnet become detached from the work piece. Failure to do so may result in personal injury.
▪Always wear approved eye protectors, ear defenders and recommended PPE when operating the machine.
▪Disconnect from power source when changing cutters or working on the machine.
▪Cutters and swarf are sharp, always ensure that hands are adequately protected when changing cutters or removing
swarf. Use a tool or brush where necessary to remove any swarf or the cutter from the arbor.
▪Before operating the machine, always ensure cutter-retaining screws are secured tightly.
▪Regularly clear the work area and machine of swarf and dirt, paying attention to the underside of the magnet base.
▪Always remove tie, rings, watches and any loose adornments that might entangle with the rotating machinery before
operating.
▪Always ensure that long hair is securely enclosed by an approved restraint before operating the machine.
▪Should the cutter become stuck in the work piece, stop the motor immediately to prevent personal injury. Disconnect
from power source and turn arbor to and from. Do not attempt to free the cutter by switching the motor on and off.
Wear safety gloves to remove the cutter from the arbor.
▪If the machine is accidentally dropped, always thoroughly examine the machine for signs of damage and check that it
functions correctly before resuming drilling.
▪Regularly inspect the machine and check for any damaged or loose parts.
▪Always ensure when using the machine in an inverted position that only the minimum amount of coolant is used and that
care is taken to ensure that coolant does not enter the motor unit.
▪Cutting tools may shatter, always position the guard over the cutter before activating the machine. Failure to do so may
result in personal injury.
▪On completion of the cut, a slug will be ejected.
▪When not in use always store the machine in a safe and secure location.
▪Always ensure that approved Unibor ™agents conduct repairs.
6) OPERATING INSTRUCTIONS
▪Keep the inside of the cutter clear of swarf. It restricts the operating depth of the cutter.
▪Ensure that the coolant bottle contains sufficient cutting oil to complete the required operating duration. Refill as required.
▪Occasionally depress the pilot to ensure cutting fluid is being correctly metered.
▪To start the machine, follow the control panel operation instructions. The Unibor machine is fitted with a dual motor protection
system to fully ensure safety and extended life of the motor. The CutSmart protection (found on the control panel) gives a clear
and visible indication to the user of torque being applied to the motor, once the prescribed level is reached the motor is
protected by automatic cut out. To re-start your machine, the operator will simply press the start button again (blue tapping
button should a protection mode occur during tapping). If, however the speed controller protection is activated, this is torque
sensor regulated at a pre-determined value above CutSmart (should CutSmart fail to operate) the operator is required to press
the start button twice to re-activate the machine.
▪Always switch off the motor by depressing the green start/stop button or blue button depending upon operation. Do not switch
off the motor by pressing the magnet switch.
▪Apply light pressure when commencing the cut of a hole until the cutter is introduced into the work surface. Pressure can then
be increased sufficiently to load the motor. Excessive pressure is undesirable; it does not increase the speed of penetration and
will cause the safety overload protection device to stop the motor (the motor can be restarted by operating the motor start
button) and may cause excessive heat which may result in inconsistent slug ejection
▪Always ensure that the slug has been ejected from the previous hole before commencing to cut the next.
▪If the slug sticks in the cutter, move the machine to a flat surface, switch on the magnet and gently bring the cutter down to
contact the surface. This will usually straighten a cocked slug and allow it to eject normally.
▪Apply a small amount of light oil lubricant regularly to the slide.
▪Cutter breakage is usually caused by insecure anchorage or a loosely fitting slide (Refer to routine maintenance instructions).
Only use approved cutting fluid.
▪Unibor cutting fluid has been specially formulated to maximise the cutters performance.

7) EXTENSION CABLE SELECTION
The machines are factory fitted with a 9 ¾ft length of cable having three conductors 16AWG
LIVE, NEUTRAL and EARTH. If it becomes necessary to fit an extension cable from the power
source, care must be taken in using a cable of adequate capacity. Failure to do so will result in a
loss of traction by the magnet and a reduction of power from the motor.
Assuming a normal AC supply of the correct voltage, it is recommended that the following
extension lengths shall not be exceeded:
For 120v supply: 11 ½ ft of 3 core x 16AWG
ALWAYS DISCONNECT THE MACHINE FROM THE POWER SOURCE BEFORE CHANGING CUTTERS.
8) MOUNTING OF CUTTERS
The machine has been made to accept cutters having 3/4” dia. Weldon shanks.
The following procedure is to be used when mounting cutters:
▪Lay the machine on its side with feed handles uppermost, ensuring arbor is wound down
to its lowest point to enable access to socket screws RD4066.
▪Take appropriate pilot and place through the hole in the cutter shank. Insert shank of
cutter into bore of arbor, ensuring alignment of two drive flats with socket screws.
▪Tighten both screws using hexagon key.

9) REMEDIES FOR HOLE MAKING PROBLEMS
Problem
Cause
Remedy
1) Magnetic base
won’t hold
effectively
Material being cut may be too thin for efficient holding.
Swarf or dirt under magnet.
Irregularity on magnet contact or workpiece.
Insufficient current going to magnet during drilling
cycles.
Attach an additional piece of metal under the magnet, or
mechanically clamp magnetic base to work-piece.
Clean magnet.
Use extreme care; file any imperfections flush to surface.
Confirm power supply and output from control unit, check
supply cable.
2) Cutter skips out
of centre-punch
mark at initiation
of cut
Magnetic base is not holding effectively.
Worn arbor bushing and/or ejector collar.
Too much feed pressure at start of cut.
Cutter is dull, worn, chipped or incorrectly sharpened.
Poor centre-punch mark; weak pilot spring; pilot not
centred in centre-punch mark.
Worn or bent pilot, worn pilot hole.
Loose bolts on motor bushing support bracket, main
casting or loose gib adjusting set screws.
See causes and remedies above.
New arbor bushing is needed.
Light pressure only is needed until a groove is cut. The
groove then serves as a stabilizer.
Replace or re-sharpen. Sharpening service is available.
Improve centre-punch and/or replace worn parts
Replace part or parts
Adjust where necessary
3) Excessive
drilling pressure
required
Incorrectly re-sharpened, worn or chipped cutter.
Coming down on swarf lying on surface of workpiece.
Gib strips out of adjustment or lack of lubrication.
Swarf accumulated (packed) inside cutter.
Re-sharpen or replace.
Take care not to start a cut on swarf.
Adjust setscrews and lubricate.
Clear cutter.
4) Excessive cutter
breakage
Steel swarf or dirt under cutter.
Incorrectly re-sharpened or worn cutter.
Cutter skipping.
Slide needs adjustment.
Cutter not attached tightly to arbor.
Insufficient use of cutting oil or unsuitable type of oil.
Incorrect speed
Remove cutter, clean part thoroughly and replace.
Always have a new cutter on hand to refer to for correct
tooth geometry, together with instruction sheet.
See causes and remedies (2).
Tighten grub screws supporting the slide.
Retighten.
Inject oil of light viscosity into the coolant-inducing ring and
check that oil is being metered into cutter when pilot is
depressed. If not, check pilot groove and arbor internally for
dirt or apply oil externally. (Even a small amount of oil is
very effective).
Ensure correct gear is used for the cutter.
5) Excessive cutter
wear
See cause and remedy above
Incorrectly re-sharpened cutter.
Insufficient or spasmodic cutting pressure.
Refer to instructions and a new cutter for proper tooth
geometry.
Use sufficient steady pressure to slow the drill down. This
will result in optimum cutting speed and chip load.

FITTING INSTRUCTIONS
▪Dependent upon the size of the pipe to be cut (see illustrations) attach adjustable angle
plates RD3328 with cap screws RD4325 and washers RD4205 (4 off each) to the magnet
sides. Do not tighten.
▪Locate the machine on the centreline of the pipe taking care that the magnet is in line with
the longitudinal axis of the pipe.
▪Switch on the magnet and move the sliding plates down to the outside diameter of the
pipe. Tighten the screws on both sides by hand then check once again that the full length
of the moving plates is touching the pipe at the front and back, fasten the plate securely.
Feed the safety strap through the lugs at the front of the housing, around the pipe and pull
tight.
▪When cutting the hole DO NOT use excessive pressure but rather let the cutter ease into
the cutting surface.

▪Unscrew the two grub screws at the top of the arbor.
▪When the arbor has become detached from the spindle this can then be removed.
▪Remove the arbor support bracket and guard with the arbor retained.
▪Mount the chuck using the chuck adaptor RD33153.
▪Replacing the chuck is the reverse sequence.
15) MAINTENANCE
In order to ‘get the best life’ out of your Unibor machine always keep it in good
working order.
A number of items must always be checked on Unibor machines.
Always before starting any job make sure the machine is in good working order and that
there are no damaged or loose parts. Any loose parts must be tightened.
Before proceeding with any maintenance work be certain that the power supply is
disconnected.

Visually check the machine for damage.
The machine must be checked before operation for any signs of damage that will affect the
operation of the machine. Particular notice must be taken to the mains cable, if the machine
appears to be damaged it should not be used, failure to do so may cause injury or death.
Check operation of the machine.
The machines operation must be checked to ensure that all components are working
correctly.
Machine Brushes
Should be checked to make sure there is no abnormal wear present (this should be checked
at least once a week if used frequently). If the brush has worn more than 2/3 of the original
length, the brushes should be changed. Failure to do so may cause damage to the machine.

Magnetic base
Before every operation the magnetic base should be checked to make sure that the base is
flat and there is no damage present. An uneven magnet base will cause the magnet not to
hold as efficiently and may cause injury to the operator.
Adjustment of slide and bearing bracket alignment.
An essential requirement of the machine is that the slide can move in a smooth and
controlled manner, free of lateral movement and vibration.
This situation can be maintained by periodic adjustment of the slide and is accomplished in
the following manner:
1. Place the machine in an upright position and, by means of the capstan, raise the slide
to its highest position. Clean the brass gib strips and apply a small amount of light
machine oil to the wear surfaces.
2. Now lower the slide back to its lowest position. Bring the slide into the center of the
dovetail slide housing and loosen screws thus allowing free movement of the arbor
support bracket.
3. Commencing with the middle screws, gently feed in all the screws until slight
resistance is encountered.
4. Operate the slide up and down a few times to test the movement and make any
further necessary adjustments. Try to ensure that all the screws are exerting a
uniform pressure on the slide from top to bottom. A perfectly adjusted slide will
operate freely up and down without any sideways movement.
5. Now raise the slide to its highest position. Slightly undo the arbor bearing bracket
and, using fingers only, tighten the screws.
6. Place the machine on a steel plate, connect to power supply and switch on the
magnet. Start up the motor. If the arbor is incorrectly aligned, the arbor support
bracket will be seen to oscillate. Make any necessary further adjustments to the
bracket to ensure correct alignment of the spindle and finally tighten the screws
using a spanner. Lastly tighten the arbor bearing bracket.
Check machines grease.
The gearbox grease should be checked once a month to ensure all moving components are
covered to prevent wear. The grease should be changed at least once a year to ensure you
gain the best from your machine.
Check Armature of the machine.
This should be checked at least once a month to check that there are no visual signs of
damage to the body or to the commutator. Some signs of wear will be seen on the
commutator over a period but this is normal (this is the part that comes into contact with
the brushes) however, if there are any signs of abnormal damage the part should be
replaced.
