4) Operating instructions
Operational safety
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.
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 or gasses. 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.
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
RD4329, or other means), 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 and ear protectors 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.
Before operating the machine, ALWAYS ensure cutter-retaining screws are secured tightly.
Regularly clear the work area and machine of swarf and dirt, paying particular attention to the underside of the magnet
base.
ALWAYS remove tie, ring, 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 ‘fast’ in the work piece, stop the motor immediately to prevent personal injury. Disconnect from
power source and turn arbor to and fro. DO NOT ATTEMPT TO FREE THE CUTTER BY SWITCHING THE MOTOR
ON AND OFF.
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 that nuts and screws are tight.
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. DO NOT operate the machine if the ejected slug may cause injury.
When not in use ALLWAYS store the machine in a safe and secure location when not in use.
ALLWAYS ensure that approved ROTABROACH™ agents conduct repairs.
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, first switch on the magnet by turning the rotary switch to position <I>. Then start the motor by
depressing the GREEN start button.
ALWAYS switch off the motor by depressing the RED stop button. DO NOT switch off the motor by turning the magnet
switch off.
Apply light pressure when commencing to cut 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 could 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
make contact with 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 slide and arbor support bearing.
Insecure anchorage, a loosely fitting slide or a worn bearing in the arbor support usually causes cutter breakage.
SPEED SELECTION
The machine is equipped with a step-less variation of speed range.
The step-less variation is adjusted by rotating the disk (which is graduated into six numerically designated segments) and
is located on top of the motor.
Before cutting holes the work piece material specification must be determined to facilitate the correct cutting speed
selection (See section Cutting speeds). Site conditions, e.g. diameter and condition of cutter, material condition, material
thickness, etc must also be taken into account when determining the suitable cutting speed. The speed and feed rate must
continuously be monitored and adjusted to ensure that optimum cutting conditions prevail.
EXTENSION CABLE SELECTION
The machines are factory fitted with a 3 metre length of cable having three, 1.5mm² conductors, 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 110v supply: 3.5metres of 3 core x 1.5mm²
For 230v supply: 26 meters of 3 core x 1.0mm²

5) Cutsmart feature
‘CutSmart’ is a new feature from Rotabroach.
Designed to help you to get the best out of your machine. It does this by way of a visual indicator.
The visual indicator shows when you are using the drill correctly within its specification this is done by
way of a Tri colour LED to the Right of the magnet on LED.
During operation if you are drilling correctly this will stay GREEN. However as you put more pressure
onto the drill increasing its workload above its correct operation the LED will start to change colour to
ORANGE. This indicates that you are putting more wear on the machine and the cutter which will
eventually cause damage to your machine. If further pressure is put on the machine the LED will
eventually turn RED and the motor will cut off and will not be allowed to be turned back on for
approximately 5 seconds. This is a safety feature to protect you and the machine from damage.
Ideally to get the most out of your machine you need to keep the LED green when drilling. If it starts to
turn orange release some pressure.
The panels are set to cut off when the machine reaches the maximum allowed current.
The magnet is also protected by a 2A fuse
Care must be taken when handling the PCB as they are static sensitive please ensure you are earthed.
As the PCB contains some delicate components please do not flash test this equipment.

ALWAYS DISCONNECT THE MACHINE FROM THE POWER SOURCE BEFORE CHANGING CUTTERS.
6) MOUNTING OF CUTTERS
The machine has been made to accept cutters having 19.05mm (3/4”) dia. 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 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.
6) 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 work-piece.
Insufficient current going to magnet during drilling
cycles.
Attach an additional piece of metal under work-piece where
magnet will be located, 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 centrepunch 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.
Replace! Only a few thousandths wear permissible. 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.
Gibs 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-ways need adjustment.
Cutter not attached tightly to arbor.
Insufficient use of cutting oil or unsuitable type of
oil.
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 sideway.
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).
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.

11) PIPE ADAPTOR KIT RD2311
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 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.

12) CHUCK CONVERSION.
To remove the arbour lay the machine on its side.
Unscrew the two grub screws at the top of the arbor
Some early machines will only have spanner flats on the arbor.
When the arbor has become detached from the spindle this can then be removed
Remove the arbour support bracket and guard with the arbour retained.
Mount the chuck using the chuck adaptor RD33153.
Replacing the chuck is the reverse sequence.
13) Tips for keeping your machine in correct working
order.
In order to ‘get the best life’ out of your Rotabroach machine always keep in good
working order. A well maintained machine is a happy machine.
A number of items must always be checked on Rotabroach 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.
Machine must be checked before operation for any signs of damage that will affect the operation
of the machine. Particular notice must be taken of 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 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 centre 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 supply and switch on 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 the machine.
Check Armature of the machine.
This should be checked at least 1 per month to check that there are visual signs of damage to the
body or to the commutator. Some signs of wear will be seen on the commutator over a period of
time this is normal as this is the part that comes in contact with the brushes but any signs of
abnormal damage and the part should be replaced.
