We recommend using a piece of card stock on the Table when
leveling the drill bits to avoid drilling into the drill strip. This will
lengthen the life of your drill bits and keep them sharper.
Remove one (1) of the two (2) Access Guard Screws using
the 1/8” Hex Wrench (HEX-18). Swing the Access Guard as
shown in diagram 4-40 to gain access to the motor shaft.
Insert the Spindle Rotation Tool (FMM9-957A) into the end of
the motor shaft through the opening in the top of the machine
shroud until the notch in the Spindle Rotation Tool fits into the
keyway securely.
Swing the access cover located on the front of the heads to
one side allowing access to the spindle and chuck.
Turn the Spindle Rotation Tool by hand until the Insert Retainer
Screw can be seen in the opening.
Turn the rocker switch labelled Table Motor on. Stepping on
the foot pedal, raise the table so that it meets the bottom of the
pressure foot assembly. By keeping the foot pedal activated
during steps 4.3.7 through 4.3.8 the table will stay in the full
upright postion.
Using the 7/32” Hex Wrench (HEX-732-T), loosen the insert
retainer screw approximately one half turn (loosening too
much may cause the insert retainer screw to come out com-
pletely). Retighten the insert retainer screw until it is snug but
not tight; this will allow you to raise or lower the chuck without
too much play. Hold onto the Spindle Rotation Tool to pre-
vent the belts from turning. Lower the height of the Chuck by
turning it counter-clockwise. Raise the height of the Chuck by
turning it clockwise.
When the drill bit is just touching the drill strip, re-tighten the
insert retainer screw. This may require you to turn the Spindle
Rotation Tool until the Insert Retainer Screw is again access-
able through the opening.
Lower the table
Repeat steps 4.3.3 through 4.3.9 on the remaing Drill Bits so
that they are all level with each other.
REMOVE THE SPINDLE ROTATION TOOL FROM THE MO-
TOR SHAFT. Leaving this attached can cause injury to the
user as it can fly out of the machine upon startup.
Replace all the Access covers and Access Guards so that they
cover the motor shaft opening and the retainer screw open-
ings.
