CAUTION: ALWAYS ensure that the machine is fully stopped before attempting to change gears! NEVER
change gears on a running machine!
OPERATION-GENERAL
WARNING: Always ensure that the magnet is adhered properly to the work piece before beginning
drilling.
NOTE: If mounting to a curved surface beam, mount the machine parallel to the curve in the work
piece.
WARNING: Avoid operating at more than 90 degrees from horizontal. When
drilling at such an angle take precautions to prevent cutting coolant from
entering the motor. Paste-type coolant should be used.
1.
First fit tool into arbor and line up with intended center of cut. Then switch
magnet on.
2.
Press green motor on button to start motor. Use the crank handle to feed to
work. Always use very light pressure when beginning the cut and just as the
tool is breaking through. The crank handle offers tremendous leverage; so do
not use too much force. Allow the cutting tool to determine the pace. With
experience, the operator will be able to determine the best pace to feed to
the work. There should be some degree of audible slowing of the motor but
not bogging in the cut. Correct cutting speed with a properly sharp annular cutter will produce long
unbroken chips, which produce a “bird’s” nest. shaped bundle of chips around the cut.
NOTE: Always ensure that the cutting tool is sharp. A dull cutter typically will have finer and/or choppy
shavings.
WARNING: ALWAYS clear chips when there is too much build-up. Excessive chip build-up could result in
a jammed cutter or other hazardous situation.
WARNING: the slug ejects at end of cut and is very hot. Always provide a method of catching the slug,
where the ejected slug may cause injury to people below.
Note: Lock the slide lock on the side of the machine in the fully raised position when at rest to prevent
the slide from accidentally slamming down - remember to unlock it again before commencing drilling.
CAUTION: Never attempt to cut half-circles or to stitch drill (drill overlapping holes) with a TCT cutter.
This may destroy the cutter.
CAUTION: Never attempt to re enter a half-finished cut if the magnet has been turned off and the
machine shifted in the interim. This may destroy the cutter.
TWIST DRILLING
If twist drilling is desired, the arbor support bracket must be removed by removing the three socket-head
