NOTE: Replace (do not reuse) hydraulic screws and
sealing washers (see Figure 7-18). Ensure bolt
threads, manifold threads and hose connectors are
free of rubber seal particles.
9. Carefully return cylinder to table base and fasten
with three new mounting screws. Ensure not to
crimp hydraulic cable.
10. Operate floor lock several times to ensure proper
operation. Inspect for leaks as follows:
a. Fully extend floor locks.
b. Visually check for signs of dripping oil from
cylinder.
c. Run finger along cylinder shaft to check for
hydraulic fluid. A slight film is normal and is
required to lubricate seals.
d. If oil is excessive enough to form a drip, replace
cylinder.
7.9 FLOOR LOCK FOOT (LEVELING
MOUNT) REPLACEMENT
Replace floor lock foot or leveling mount as follows:
1. For units built prior to C0406007-017 (non-swivel
foot):
NOTE: If table equipped with original floor lock foot
(non-swivel) is used on a very uneven floor, the
effectiveness of the floor lock system is reduced
when one or more of the feet do not apply enough
pressure on the floor when in fully locked position.
If this situation exists, replace all four feet with new
swivel-foot that is also faster and easier to adjust.
See
Step 2 below to change to new foot.
a. Remove Floor Lock Cylinder (see S
