5) OPERATIONAL SAFETY PROCEDURES
READ BEFORE USING THE MACHINE
•When using electric 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 operating the machine, inspect all electrical supply cables (including extension cords) and replace if damaged. Do not
use if there are any signs of damage.
•Only use extension cords approved for the site conditions.
•Before operating the machine, always check for the correct functioning of all operational systems, switches, magnet etc.
•Before operating, the machine must be securely restrained to a fixed object by using the safety strap and stationary rings.
Attach the stationary rings onto the magnets uppermost side holes 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 safety glasses, hearing protection and other recommended PPE when operating the machine.
•Disconnect from power source when changing cutters or working on the machine.
•Cutters and cuttings are sharp, always ensure that hands are adequately protected when changing cutters or removing
cuttings. Use a tool or brush where necessary to remove any cuttings from the arbor.
•Before operating the machine, always ensure cutter-retaining screws are secured tightly.
•Regularly clear the work area and machine of cuttings and dirt, paying attention to the underside of the magnet base.
•Always remove ties, 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 back and forth. 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.
•When not in use always store the machine in a safe and secure location.
•Always ensure that an approved Kimball Midwest service center conducts repairs.
6) OPERATING INSTRUCTIONS
•Keep the inside of the cutter clear of cut material. It restricts the operating depth of the cutter.
•Ensure that the coolant bottle contains sufficient cutting oil to complete the required operations. Refill as required.
•Occasionally depress the pilot to ensure cutting fluid is being correctly metered.
•To start the machine, follow the control panel operating instructions. The Kimball Midwest Roto-Kut™ machine is fitted with a
dual motor protection system to fully ensure safety and extend the life of the motor. The CutSmart™protection (found on the
control panel) gives a clear and visible indication to the user of torque being applied to the motor, if too much pressure is
applied the drill will shut off automatically. To re-start the machine, press the start button again. If the speed controller
protection is activated, press the start button twice to re-activate the machine.
•Always switch off the motor by depressing the green start/stop button (or blue button) depending upon operation. Do not
switch off the motor by pressing the magnet switch.
•Apply light pressure when starting the cut until the cutter is cutting into the work piece. 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 from the previous hole has been ejected before starting to cut the next hole.
•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
contact 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.
•Cutter breakage is usually caused by insecure anchorage or a loosely fitting slide (Refer to routine maintenance instructions).
•Only use approved cutting fluid. Kimball Midwest offers several cutting fluids that have been formulated to maximize cutter
performance.
