• Tighten locknut and back‐off the
locknut 1/8 of a turn.
• Replace the locknut.
4. Reposition the rubber boot.

Replacing the Swivel Bar

After the first year of use, the hooks of the swivel bar and mounting brackets of the
boom should be inspected every six months to determine the extent of wear. If
these parts become worn, replacement must be made.
NOTE: For this procedure, refer to FIGURE 7.4 on page 39.
1. The swivel bar comes attached to the boom with bolt, nut, washers, and pinch guard.
NOTE: Washers should be placed against both sides of the boom mounting bracket to eliminate
damage.
NOTE: The swivel bar has three hooks on both ends to attach the sling that supports the patient
during lift.
2. Remove existing hardware and replace the swivel bar.
DO NOT overtighten the nut and bolt. This damages the mounting bracket.
