4. Carefully lift and position the top unit over the spacers on the bottom
unit. Align the (4) connection point holes in the bottom of the top
unit with the (4) spacers and threaded inserts. (Helpful hint: Use
masking tape around outside edge of spacers to hold in place during
installation. Remove tape after installation.)
5. Assemble the lockwashers, then the flatwashers onto the 5/16-18 x 4"
bolts. Then thread the bolts through the connection point and spacer,
and into the unit below. Refer to Figures 1-19 & 1-20. Tighten bolts.
6. Reinstall all brackets and cover panel. Be careful when routing wiring
and wire connectors on rear of relay box. This can affect operation of
the shaker.
After positioning the shaker (or stack) in its final
location, it is critical that the unit(s) be as level as
possible. Each of the leveling feet on a shaker or
stand has an adjustment nut (the lower one, for
leveling purposes) and a locknut (the upper one,
for securing the adjustment). See Figure 1-21.
Using a 3/4" or adjustable wrench, turn the adjustment nut (to extend the
leveling foot) to achieve a level condition. Make sure the shaker (or stack)
is leveled side-to-side and front-to-back. This can usually be accomplished
by adjusting only two feet. Verify that all four feet are in full contact with
the floor when leveling is complete. To "tune out" any vibrations, see the
Tuning the Cabinet section. After each leveling and/or tuning, secure the
adjustment in place by tightening the locknut against the base of the
cabinet/stand.
Caution Leveling feet extend only a very short distance. When unit is
leveled and tuned, with leveling feet locked in place, adjustment and
locking nuts should be no further than 1/4 inch apart.
