Caster Inspection (ZGM-6-5H)
Caster Replacement
1. The Zero-Gravity oor system contains several casters (wheels) allowing for the
proper positioning of your system for use. The casters are also equipped with
brakes to lock the casters in place.
2. As a result of long-term use, the casters may require replacement after an
extended period of time to ensure the system functions as intended. Complete
inspection to determine if replacement of any of the casters is required.
Caster Inspecon
1. While the system is not in use, move the system to an open space where there
is ample room to manipulate the base of the system without risk of colliding with
other equipment.
2. Move the system in each direction to ensure the casters are functioning as
intended and rolling smoothly across a smooth surface.
3. Apply the lock for each caster equipped on the Zero-Gravity oor system.
4. With the brakes engaged, inspect each caster for debris.
5. Apply force to the ZG system in an attempt to move the system. Apply minimal
force to move the system in an effort to prevent unintended damage to the
casters and brakes.
6. Casters exhibiting issues with rolling or braking should be replaced.
7. Contact a TIDI Products authorized representative or TIDI Products service for
repairs and / or replacement of components. Replacement and repairs may only
be completed by TIDI Products authorized personnel.
8. If additional support is needed, contact TIDI Technical Service using the provided
contact information.

1. While the system is not in use, use a ladder to access the top of the Zero-Gravity
oor system directly above the vertical column.
2. Check each of the (3) 3/8-16 x 1-inch long screws connecting the boom arm to
the boom arm mount to ensure they are in place and tight. (Figure 13)
