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 gear selectorwork 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 tremen
dous 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. Cor
rect 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. Ex-
cessive 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 overlap-
ping 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
1. first mount the Chuck to the Chuck adaptor.
2. Then insert the Chuck adaptor into the arbor, align the
proper flat with the locking screw(s) and tighten
securely with the supplied L-hex key.
3. CAUTION: Ensure that the locking screw is on a flat of the
cutter and not just against the rounded shank..
4. Insert the twist drill into the Chuck and tighten with the
chuck key.

MAINTENANCE
1. Keep the machine clean and free of chips.
2. Check for loose fittings and tighten as needed.
3. Ensure that the ventilation slots are clear so that motor can be cooled
normally. Blow low-pressure compressed air through the ventilation
slots with the motor running to keep motor clean.
THE GIBS (DOVETAIL SLIDES)
The gibs require adjustment if too loose. To adjust, loosen the lock nuts
and adjust the adjustor screws evenly while moving the handle up and
down. Adjust so that there is no free play, without any binding anywhere
in its range of travel. Then retighten the lock nuts. Periodically check,
lubricate, and adjust as needed.

THE CARBON BRUSHES
The carbon brushes are a normal wearing part and must be replaced when
they reach their wear limit.
Caution: Always replace the brushes as a pair.
To replace:
1. Remove the 4 screws and remove the motor tail cover.
2. Using pliers rotate the brush spring out of the way and slide the old
carbon brush out of the brush holder.
3. Unscrew the screw to remove the brush lead. The old carbon brush may
now be lifted away.
4. Install a new brush. Installation is the reverse of removal.
5. Replace the motor tail cover.
CARBON BRUSHES
Due to the brush design, if the machine comes to a stop without any reason,
the brushes have to be checked. The brush design stops the machine before
the carbon brushes are finished and protects the motor.
