Vibration is the root cause of
most surface finish problems.
Be sure the cutting head is
securely locked in place.
Tight connections here reduce
the chance of vibration.
SECURING THE
CUTTING HEAD
STEP 2: SET UP THE LATHE (2 Minutes)
A. Mount the Lathe to the Adapter
Move the cutting head out so that the tips will not strike the rotor as you mount the lathe.
Next, roll the machine into place and match it up with the adapter. Note that the trolley moves up
and down to accommodate different heights. The small dowel pin on the face of the adapter will fit
into either of several holes on the run-out adjustment flange. Turn the draw bar knob to thread into
the adapter securely connecting the lathe to the vehicle.
NOTE: It is very important that the machine be mounted smoothly on the adapter without prying or
forcing. Take the time to align the machine properly in order to avoid damage to the run-out adjust-
ment flange. The large draw bar knob will spin on very easily when the machine is properly aligned,
much like installing an oil filter. Tighten it by hand only.
Loosen the trolley handle so that the machine is free to rotate. Rotate the machine so that the cutting
head is in a position where there is clearance to make the cut. Be sure to check the back side of the
rotor for obstacles. Make sure there will be clearance for the chip deflector as well.
Lock the trolley
lever securely so the machine will not rotate when the motor is started.
B. Position the Lathe for Cutting
Note the Automatic Shut-Off Switch
Above. The shut-off cam will depress the
stop button when the cutting tips clear
the rotor.
Set the shut-off cam (circled) by loosening
the thumbscrew and positioning on the rail
so that the cam will depress the stop button
when the cutting tips clear the rotor.
MACHINING ROTORS CONTINUED
The Speed-Lock Cutting Head has two lock levers, one closer to the brake rotor (forward)
to release the tool arms, and one farther from the brake rotor (rear) that allows you to
lock the cutting head in position once centered over the rotor. The cutting head can
slide laterally but is limited by two roll pins; one on either side of the leading edge of
the
50-496 plate.
C. Position Cutting Head and Set Shut-off Cam
STEP 2: SET UP THE LATHE (2 Minutes)
(CONTINUED)
Loosen the forward lever and the rear knob. Slide the cutting head laterally and adjust
the tool arm depth knobs (at the rear of the cutting head) so the tool arms are evenly
spaced and will clear the rotor. Once centered over the rotor, tighten the rear lock knob
to secure the cutting head. If the cutting-head lock knob is not secure, a poor surface
finish will result; over-tightening is not required.
NOTE: The Pro-Cut will mount cutting head up on one side and cutting head down on the other.
Always start right-side up; this way, when you proceed to the other side of the vehicle, the offset
of the cutting head, and the shut-off cam will already be set.
Next you will set the shut-off cam. Crank the feed knob in until the tips clear the out-
side edge of the rotor. Loosen the cam screw and slide the cam back until it contacts
the automatic shut-off switch plunger. Tighten the cam screw. The cam will press the
shut-off switch when the tips clear the rotor.
