To LOOSEN the mesh (INCREASE the backlash), first 
loosen the outer two screws a little bit by turning them 
counterclockwise the same amount, then tighten the 
center screw by turning it clockwise.
Loosen/Tighten the three screws only in small incre-
ments to avoid over-adjustment or possible damage 
to the worm or ring gear!

10.  Now, with the DEC clutch lock lever tightened, jog the 

saddle rotationally back and forth again by hand and see 
if the backlash has decreased to a more desirable level.

11.  After the gear mesh has been adjusted to your 

satisfaction, re-install the three cover screws removed in 
Step 8, and then re-tighten the four screws on the bottom 
of the worm gear housing loosened in Step 7.

12.  Before retightening the two screws loosened in Step 6, 

use the hand controller’s up or down directional button 
to drive the DEC motor and the worm gear for a few 
seconds.  This will allow the motor to auto-center and 
align the drive shaft with the worm rod. After this is done, 
the two screws can be fully tightened.

13.  Now use the hand controller to slew the DEC axis 

at least 2 complete cycles (720 degrees) to check if 
there is any stalling or binding as a result of your mesh 
adjustment. If there is, be sure to repeat this procedure 
from the top and make the necessary adjustments. If 
there isn’t, re-attach the DEC motor housing with the 
three screws removed in Step 5.
