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
Notice that there are several mounting holes in the slide plate that can be used to lock
the cutting head. The cutting head assembly can be secured into any one of the holes.
It is a good idea to clean out these holes as well as the dovetail and plate surfaces when
you change cutting head position, as they can easily fill up with metal chips. Use the
T-handle 6mm allen wrench to remove the securing screw and center the head so the
cutting arms will straddle the rotor. It is critical that you pull the tool holder plate back
into the dovetail so that it is square as you tighten the securing screw.You can use one
hand to push the cutting head firmly back into the dovetail as you tighten the set screw
with your other hand. If the tool holder is not squarely and firmly pressed into the dove-
tail, a poor surface finish will result.
C. Position Cutting Head and Set Shut-off Cam
STEP 2: SET UP THE LATHE (2 Minutes)
(CONTINUED)
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.
