• On completion of the cut, a slug will be ejected. DO NOT operate the machine if the
ejected slug may cause injury.
[3] 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 <1>.
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 to zero.
• 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 may result in inconsistent slug ejection
• Always ensure that the slug has been ejected from the previous hole before commencing to cut the
next.
• Always cut overlapping holes as illustrated above – do not use excessive pressure and ensure
cutting fluid is reaching teeth of the cutter.
• 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.
• 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. Rotabroach cutting fluid has been specially formulated to
maximise the cutters performance. It is available in 1 litre (RD208), 5 litre (RD229), and 25 litre
(RD220) containers.
