arm, which should fully mesh with the Helical
Gear. Hold it in this position. The worm gear
shaft will extend through the housing to be
ready for the crank to be attached in a later
step.
6. Loosen the table support's locking handle,
then slide the support onto the column with
the worm gear shaft on the right side.
7.
Hold the assembly in this position while replacing the collar on the
column and ensure that the end of the rack is firmly engaged in the
groove formed between the collar and the column. However, make
sure the rack is not pinched and there is a working clearance
between the rack and collar. Firmly secure the collar with the collar
set screw (Fig. 3).
8. Tighten the locking handle to secure the table support in place.
9. Loosen the set screw in the table adjustment handle. Slide the
handle onto the worm gear's drive shaft. Tighten the set screw to
secure the handle (Fig. 4).
10. Loosen the locking handle and turn the table adjustment handle to
confirm the table will move up and down. Tighten the locking
handle to secure the table support.
11. Adjust the locking arm if the fit is too tight. Nudge up the locking
handle and slacken off the collar set screw. Adjust for a greater
working clearance between the rack and collar, then tighten the set
screw and test again until satisfied with the movement.
12. Insert the working table into its housing on the support arm and
secure with the table locking clamp.
