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 RD4329B, 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 protectors, ear defenders and recommended PPE at ALL times 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 particular 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 fro. 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. DO NOT operate the machine as the ejected slug may cause injury.
•When not in use ALWAYS store the machine in a safe and secure location.
•ALWAYS ensure that approved POWERBOR™ 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.
•ALWAYS switch off the motor by depressing the MOTOR stop button. DO NOT switch off the motor by depressing 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 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 the slide and arbor support bearing.
•Cutter breakage is usually caused by insecure anchorage, a loosely fitting slide or a worn bearing in the arbor support. (Refer to
routine maintenance instructions).
•Only use approved cutting fluid.

7) EXTENSION CABLE SELECTION
The machines are factory fitted with a 2 metre length of cable having three conductors 1.5mm²
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: 3.5 yards of 3 core x 1.5mm²
For230v supply: 26 yards of 3 core x 1.5mm²
ALWAYS DISCONNECT THE MACHINE FROM THE POWER SOURCE BEFORE CHANGING CUTTERS.
8) MOUNTING OF CUTTERS
•The machine has been made to accept cutters having 19.05mm (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.
•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.

10) 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 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.
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
3) Excessive
drilling pressure
required
Incorrectly re-sharpened, worn or chipped cutter.
Coming down on swarf lying on surface of work-
piece.
Swarf accumulated (packed) inside cutter.
Re-sharpen or replace.
Take care not to start a cut on swarf.
Clear cutter.
4) Excessive
cutter breakage
Steel swarf or dirt under cutter.
Incorrectly re-sharpened or worn cutter.
Cutter skipping.
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).
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 speed is use 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.

17) MAINTENANCE
In order to ‘get the best life’ out of your Powerbor machine always keep it in good working
order.
A number of items must always be checked on Powerbor 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
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.
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 of time, 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.
