This will be used to identify the retract line.
Connect this to the retract push connect
elbow on the power draw bar button
assembly, which is on the back and top of the assembly.
Route the other end through the button box base and out the back of the enclosure.
Connect the second, 5/32" nylon air line to the advance line
on the top front push to connect elbow.
Route the other end through the button

Philips head screws temporarily remove
the m6 x 12 millimeter socket head cap
screws from the spindle motor cover the
bracket is installed in its place the
spindle head may have to be dropped in Z
to allow the bracket to be secured this
will involve powering up the pc NC 4 40
lowering the spindle then following the
shutdown procedure described earlier
secure the bracket to the button box
cover with one m5 machine screw if
you're planning on using an frl this
will be a good point to install one find
a convenient location for the FR l then
mark the location of the screws using
the mounting bracket drill the two holes
using a number 21 drill bit then tap the
20 holes using a 10 30 second tab secure
the bracket with the provided machine
screws secure the cap into the back of
the frl using a hex wrench whines thread
seal tape two times around the threads
of the dial and secure this to the front
of the frl with an open end wrench wind
some thread seal tape two times around
the fittings on the two npt reducers
secure them into the valve housings on
either side of the frl while taking care
not to overtighten connect to push
connect bushings to the two npt reducers
attach the frl to the bracket with the
top connection ring connect the nylon
airline from the drawbar button assembly
to the right push connect then attach
the airline from the air compressor to
the left push connect remove the cap of
the FRL fill port with a hex key use a
small funnel to fill the lubricator bowl
with standard air tool oil only use oil
that is specifically designed for air
tools reinstall the fill port cap before
using the frl the air must be purged
from the system press the knob down to
lock open the lubrication adjustment
knob one half turn
the plus flush all air bubbles from the

appear in the site window and a droplet
of lubricant forms on the bottom of the
stem closed the adjustment knob a
quarter turn so that it is open
approximately a quarter turn from the
completely closed position after initial
installation the spring washer preload
adjustment needs to be completed using
two large adjustable wrenches tighten
the power drawbar to approximately the
same torque used normally to tighten the
manual drop our system with one hand
supporting the turtle holder push the
power draw bar button if the tool holder
releases tighten the power draw bar in
quarter turn increments push the power
draw bar button after each increment
until the tool holder does not release
at this point loosen the power draw bar
a quarter turn push the drawbar button
again and the tool should release the
preload will need to be checked on a
regular basis if you notice a drop in
performance repeat the preload
adjustment procedure failure to do so
could result in tool holder pull out if
the gap between the hex head screw on
the power drawbar cylinder rod and the
top of the drawbar is between one
sixteenth of an inch and one eighth of
an inch you successfully installed your
power draw bar on your PC NC for 40 if
the gap is under one sixteenth of an
inch or there is no gap then you need to
make an adjustment first release the air
pressure from the air compressor then
pull out the quick release pin swing the
power drawbar cylinder out remove the
hex head screw on the power cylinder rod
remove the m16 washer reinstall the hex
head screw and tighten securely swing
the cylinder back into place and
reinsert the quick release pin measure
the gap to ensure it is between one
sixteenth of an inch and one eighth of
an inch press and hold the power draw
bar button to release the tool holder in
spindle insert a new tool holder the
power drawbar automatically reverts to
clamp mode when the button is released
the pcmc 440 power draw bar uses a
manual push button with no means of
locking the power draw bar in the
unclamped
zishan because of this it is best to
leave a tool holder clamped in the
collet this will prevent fatigue in the
collet and extend the service life of
the power draw bar congratulations
