7. Loosen one set of bottom screws securing the vertical guide
rods. Slide one end of the machine 4 inches off the edge of the
bench. It does not matter if it is the side with the keypad or the side
without. This will give you sufficient room to reach to screws
attaching the bottom of the vertical guide rods to the base of the
machine on the overhanging side. Loosen both screws attaching the
bottom of the vertical guide rods to the base of the machine with the
10mm socket. LOOSEN 1 to 2 TURNS ONLY - DO NOT REMOVE
SCREWS. Now all four screws (top and bottom) attaching the two
vertical guide rods on the overhanging side are loose. This allows the
head to naturally set the correct spacing for these two guide rods.
8. Tighten the two bottom screws.
9. Rotate machine 180 degrees to where the other side of the machine
is overhanging the bench. Repeat Step 8-9 for this side of the
machine.
10. Tighten the screws securing the vertical guide rods: Crank the
head up to approximately the center of travel and tighten the four top
10mm bolts.
11. Re-check head pressure using the procedure used in the
Troubleshooting section of your Operators Manual. If the head
pressure still reads low, please contact CarveWright technical
support (713-473-6572) for additional instructions.
Reassembling the Machine
1. Replace the bottom cover. Replace the metal cover with the
louvers pointing into the machine (see Figure 35). Insert and tighten
the 12 screws. The four rubber feet are placed at the corners of the
machine.
2. Prepare the flexshaft assembly for re-insertion into the machine:
Gently pull the protruding flexshaft core (with squared end) out of the
sheath several inches. Push the core back into the sheath and make
sure that it slips into, and engages, the cutting motor. It will drop into
the receptacle on the motor side about 5/8ths of an inch. Turn the
core by hand and feel for resistance of the motor. If the shaft spins
without resistance, push the core inward while rotating until it drops
into the slot and engages the motor.
3. Insert the flexshaft into cutting head: Looking through the slot in
the top cover, locate the flexshaft receptacle on the top of the Z-truck.
Inside the receptacle there is a square recess that mates with the
exposed square end of the flexshaft core. Turn the chuck on the
bottom of the cutting head (open the safety cover for access) until the
square core end can be inserted into the recess. Press the flex shaft
all the way down into its receptacle. A click will be heard and felt as
the shaft snaps into place.
