2.6 Head Drive Operation Failures
The hilow motor runs, but other problems with the motor are suspected (i.e. it is noisy, it drifts, etc.).
1. Raise and lower the head section with the head 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 head motor (see Procedure 4.6 on page 4-12). If this solves the problem,
go to “Final Actions” on page 2-9. Otherwise, continue to Step 2.
2. Examine the mounting clevis pins and cotter pins on the head motor drive. The clevis pins are
installed correctly.
Yes No
Install the head motor clevis pins correctly to attach the head motor to the bed
frame. If this solves the problem, go to “Final Actions” on page 2-9. Otherwise,
continue to Step 3.
3. Raise and lower the head section under a load condition. The head drive runs quietly.
Yes No
Examine for damage to the head motor. Replace if necessary (see Procedure 4.6 on
page 4-12). If this solves the problem, go to “Final Actions” on page 2-9. Otherwise,
continue to Step 4.
4. Using the head function, raise and lower the head section. The head motor retains its position, and
does not drift or coast.
Yes No
Replace the head motor (see Procedure 4.6 on page 4-12). If this solves the problem,
go to “Final Actions” on page 2-9. Otherwise, contact Hill-Rom Technical Support.
5. Go to “Final Actions” on page 2-9.
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 (see Procedure 4.9 on page 4-17). If this solves the problem,
go to “Final Actions” on page 2-9. Otherwise, continue to Step 2.
2. Examine the mounting clevis pins and cotter pins on the foot motor drive. The pins are installed
correctly.
Yes No
Install the mounting pins correctly to attach the foot motor to the bed frame. If this
solves the problem, go to “Final Actions” on page 2-9. Otherwise, continue to Step 3.
