2.7 Foot Drive Operation Failures
The foot motor runs, but other problems with the motor are suspected (i.e., it is
noisy, it drifts, etc.).
1. Raise and lower the foot section with the foot function. Look for evidence
of physical damage to the drive system (i.e., check for a bent motor shaft,
loose metal, etc.). The drive system passes inspection.
Yes No
Replace the foot motor (refer to procedure 4.6). If this solves the
problem, go to “Final Actions” on page 2-10. Otherwise,
continue to step 2.
2. Inspect the mounting clevis pins and cotter pins on the foot motor drive.
The clevis pins are installed properly.
Yes No
Install the foot motor clevis pins properly to secure the foot
motor to the bed frame. If this solves the problem, go to “Final
Actions” on page 2-10. Otherwise, continue to step 3.
3. Raise and lower the foot section under a load condition. The foot drive runs
quietly.
Yes No
Inspect for damage to the foot motor. Replace if necessary (refer
to procedure 4.6). If this solves the problem, go to “Final
Actions” on page 2-10. Otherwise, continue to step 4.
4. Using the foot function, raise the foot section up and down. The foot motor
retains its position, and does not drift or coast.
Yes No
Replace the foot motor (refer to procedure 4.6). If this solves the
problem, go to “Final Actions” on page 2-10. Otherwise, contact
Hill-Rom Technical Support.
