GENERAL SAFETY RULES

WARNING!
Read all safety warnings, instructions, illustrations, and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire, and/or serious injury.

Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

Work area safety

• Keep work area clean and well lit. Cluttered or dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
• Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

Electrical safety

• Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
• Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
• Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
• Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
• When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
• If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.
  NOTE The term “residual current device (RCD)” can be replaced by the term “ground fault circuit interrupter (GFCI)” or “earth leakage circuit breaker (ELCB)”.

Personal safety

• Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
• Use personal protective equipment. Always wear eye protection. Protective equipment such as a dust mask, non-skid safety shoes, hard hat or hearing protection used for appropriate conditions will reduce personal injuries.
• Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents.
• Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
• Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
• Dress properly. Do not wear loose clothing or jewellery. Keep your hair and clothing away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
• If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.
• Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second

Power tool use and care

• Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
• Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
• Disconnect the plug from the power source and/or remove the battery pack, if detachable, from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
• Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
• Maintain power tools and accessories. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
• Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
• Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.
• Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

OPERATIONAL SAFETY PROCEDURES

READ BEFORE USING THE MACHINE

• Always take care when lifting and transporting this this machine. The maximum lifting weight for one person is 25kgs. See Fig.1
• 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 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, follow the control panel operation instructions.
• ALWAYS switch off the motor by depressing the MOTOR stop button.
• 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 do not use water-diluted cutting oil. Rotabroach cutting fluid has been specially formulated to maximize the performance of the cutter. It is available in 1 litre (RD208) and 5 litre (RD229).
  1. Unscrew the cap
  2. Pour neat oil into the coolant bottle
  3. Screw the cap back on the bottle firmly
  4. Open the tap. Fig.2

CONTROL PANEL OPERATION

1. Magnet ON
   Move the mechanical magnet switch, located on the back of the magnet to the ON position. The LED will light up either red or green depending on if sufficient magnetic adhesion has been achieved.

2. Motor switch

4. Cutting
   See below for a detailed description of the CutSmart™ visual indicator

5. Motor OFF
   To stop the motor, press the RED switch. The motor will stop, and the GREEN switch will turn on. Go back to step 3 to start over.

CutSmart™ Technology

Green Zone
Perfect, try to keep in the green zone for the best cut and optimum machine performance.

Yellow Zone
A little too much pressure on the drill ease off to get back to the green zone.

Red Zone
Overload: Back off immediately as too much force will cause the motor to cut off if you continue.

CutSmart™ Technology
Designed for you to get the most out of your machine and your cutters. CutSmart has an easy-to-read panel that indicates when you are drilling with too much force, which will damage the machine and the cutters.

Allow the cutter to do the work and you will find that a much smoother hole and faster drilling time is achieved.

GEAR SELECTION
The Element 40 PERM magnetic drill is fitted with a 2 speed gearbox. The gear is used to reduce the output speed when using larger cutters.

• Up to 30mm diameter cutters, gear position 1 should be used.
• 30 – 40mm diameter cutters, gear position 2 should be used.

EXTENSION CABLE SELECTION
The machines are factory fitted with a 3-meter 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.

Should the mains cable become damaged and need replacing, please ensure this is carried out only be an approved Rotabroach Engineer.

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: 26metres of 3 core x 1.5mm²

ALWAYS DISCONNECT THE MACHINE FROM THE POWER SOURCE BEFORE CHANGING THE CUTTERS.

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 the arbor is wound down to its lowest point to enable access to socket screws RD4066.
• Take the appropriate pilot and place it through the hole in the cutter shank. Insert the shank of the cutter into the bore of the arbor, ensuring the alignment of two drive flats with socket screws.
• Tighten both screws using the hexagon key.

CAPSTAN OPERATION

The quick-release capstan is a feature offer that offers the user simple dual- side operation.

To remove the capstan, simply do the following;

1. Press in the central button on the capstan hub, holding onto the capstan arms.
2. With the button pressed in, pull the capstan away from the main body, holding on to the capstan’s arms. 3: Re-insert the hexagonal shaft into the hexagonal slot to attach the capstan.

REMEDIES FOR HOLE-MAKING PROBLEMS

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.

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

| Incorrectly re-sharpened, worn or chipped cutter.| Re-sharpen or replace.
required| Coming down on swarf lying on surface of work- piece.

Gibs out of adjustment or lack of lubrication. Swarf accumulated (packed) inside cutter.

FITTING THE CHUCK

• To remove the arbor lay the machine on its side.
• 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.

MAINTENANCE

In order to ‘get the best life’ out of your Rotabroach machine always keep it in good working order. 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.
The machine must be checked before the 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 the operation of the machine.
The machine’s 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 the 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 the 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 the 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 the machine’s 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 the 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.
