ELECTRICAL SYSTEM
Check the black serial number tag on the left rear corner of the
machine base for voltage/phase/hertz and amperage required.
This tag also lists the time delay fuse amperage and the wire
size for the supply conductor.
Check the proper rotation of the drill head drive shaft. The
rotation must be the same as indicated by the arrow decal
located on the side of the belt guard on the left hand side of
the machine. If the shaft is turning in the opposite direction,
change two of the wires in the incoming power cable of the
machine, choosing from the red, black and/or white wires.
If the drill head shaft is rotating in the opposite direction of
the arrow, the hydraulic system will not be able to create any
pressure.
STARTING
Two electric motors provide the power for this machine; one is
for the hydraulic power system and the other is for the spindle.
The electric motor for the hydraulic system drives a hydraulic
pump that creates the force to push the drill heads down. The
spindle motor drives the drill head spindles through a set of
belts and pulleys.
The two motors are started separately by pushing the corre-
sponding start button indicated by the appropriate symbols on
the pushbutton panel. This feature is needed for setting drill
bits, for round cornering and slotting. This allows the hydraulic
system to be running while the spindle is not.
Both motors are turned off by a red mushroom stop pushbutton
located on the left side of the panel. This is a safety feature that
stops the entire machine.
WARNING
This machine is equipped with a safety interlock system which
prevents the spindle motor from being started when the hinged
top cover is raised, and automatically turns the spindle motor
off if the cover is raised after the spindle motor is turned on.
This safety feature is provided to prevent accidental contact
with moving parts. This feature must not be altered or tam-
pered with.
OPERATION
A maximum of five drilling heads can be used on this ma-
chine with 1/4” drill bits and smaller. A maximum of four
drill heads with 3/8” drill bits and a maximum of three drill
heads with
1/2” drill bits.
NOTE: Use drill extensions on all drill bits that have a
threaded hole in the top of the drill bit.
SETTING DRILL HEADS
A) Raise the hinged top cover.
B) Insert the drill bits into the drill head spindles. Use drill exten-
sions on all bits that have a threaded hole in the top end.
C) Make sure that the retainer on the spindle is down over the
horseshoe lock washer.
D) Move the drill heads to the desired locations by loosening
the clamp screws, then move to the left or right of zero on the
scale in front of the drill heads. The line that extends down from
the diamond logo on the cover plate is to be used to line up with
the graduations on the scale. Then lock the drill heads in place.
E) Adjust the spindles to their uppermost position by loosening
the set-screw located in the front of the drill head in the clamp
block at the top. Turn the knurled caps on top of the drill heads
in a counterclockwise direction until they are at their uppermost
position.
F) Turn on the hydraulic power system by pressing the green
pushbutton that is below the symbol showing a drill bit with a
vertical double arrow. DO NOT TURN ON THE SPINDLE
MOTOR.
G) Depress the foot pedal and hold it down. The drill heads will
come down. Adjust all drill heads individually by turning the
knurled knob on top of the drill heads clockwise until they just
cut through a single piece of 20lb paper.
H) Remove your foot from the foot pedal and the drill heads will
come back up. Tighten the set-screw in the drill heads as referred
to in step (E). CAUTION: Do not over-tighten. To lock more
than finger tight is unnecessary and will cause damage to the
threads on the spindle sleeve.
I) Lower the hinged cover before turning the spindles on.
MOVEABLE TABLE INSTRUCTIONS
The moveable table is a unique feature that allows the operator
to drill several holes without moving the stock by hand. Every
MT paper drill is equipped with an adjustable step bar that has
five adjustable stops. The moveable table can become a station-
ary table by using the table lock plunger located in the front of
the machine under the table.
