Element 75 Manual
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 neat cutting fluid, do not use water diluted oil. Rotabroach cutting fluid has been specially formulated to maximize the
cutters performance. It is available in 1 litre (RD208) and 5 litre (RD229).
