PC-095 Troubleshooting Guide 1
PC-095 Troubleshooting
This Troubleshooting Guide walks you step-by-step through the
diagnosis of PC-095 customer problems. It is important to follow these
steps carefully, to ensure that the problem is diagnosed correctly, and
therefore the appropriate repair action is taken.
Assembly Issues
I cannot install the headrest frame.
Be sure the screws located near the end of each post have been
removed prior to attempting to install the headrest frame.
Getting Started
1. If the chair has cosmetic damage, replace the damaged part.
2. Choose from the following:
To Troubleshoot This
Issue Do the following:
My chair will not
recline/incline
properly.
See "Electric Recline" on page 2.
My chair makes noise
when I incline/recline. See "Noise" on page 3.
My chair feels bumpy
when reclining
The complex mechanism that enables the
footrest to continue to fold inward after the
chair is fully inclined creates a slight bump
when reclining, as it locks, and when inclining,
when it unlocks.
My recline lever is
broken. Replace the armrest core.

Electric Recline
The Chair Recline/Incline Works Intermittently
If your chair reclines/inclines intermittently, requiring you to unplug it
from the wall outlet and plug it back in, be sure you are holding the lever
in the recline or incline position for five seconds. It takes several
seconds for the recline actuator to engage. If you pull and push the lever
back and forth in different directions, the recline actuator cannot
engage in any particular direction.
The Chair Will Not Recline or Incline
1. Verify that the chair is plugged into a working wall outlet.
2. Verify that there is weight distributed across the chair (not just on
the back of the seat) when attempting to recline the chair, as this will
prevent the chair from reclining.
3. Verify that there is nothing pressing against the footrest when
attempting to recline the chair, as this will prevent the chair from
reclining.
4. Replace the recline actuator.
5. If replacing the recline actuator does not resolve the problem:
a. Remove the left-hand armrest core (see repair instructions titled
Replacing the Armrest Core
).
b. On the bottom of the chair, open the connector junction box
cover, disconnect the connectors, then plug the armrest core
directly into the recline actuator connector. Test the armrest core
function.
c. If the armrest does not work, replace the left-hand armrest core
w/switch.
d. If the armrest core works, then the electrical cable that connects
the recline actuator to the armrest is defective; replace the chair.
My footrest is broken. Replace the mechanical footrest assembly.
My footrest pads drag
on the ground when I
fully retract the
footrest.
When installing the seat pad, the lower corners
of the footrest frame must be installed into the
corresponding holes in the bottom corners of
the seat pad, otherwise the bottom of the seat
pad will not retract along with the footrest.
To Troubleshoot This
Issue Do the following:
PC-095Troubleshooting Guide 3
Noise
It is important to distinguish between typical noises caused by
upholstery rubbing together, clicking of the electronic recline switch, or
normal functioning of the folding footrest assembly from those that are
out of the ordinary.
Rubbing or squeaking sound
This noise is normal, caused by the body pad rubbing against the side
of the chair. To minimize this noise, Do the following:
1. Reinstall the pads, ensuring that they are centered carefully during
installation.
2. Check to see if there is less clearance between the backrest and the
sides of the chair on one side of the chair than there is on the other. Try
to center the backrest between the two sides of the chair (like you would
a bicycle tire between the two brake pads).
Soft clicking sound when engaging the recline handle
This noise is normal.
Slight mechanical noise when reclining or inclining
The complex mechanism that enables the footrest to continue to fold
inward after the chair is fully inclined emits a minor mechanical sound
when reclining, as it locks, and when inclining, when it unlocks.
Loud popping or clunking sound when reclining
This may indicate a known issue with an earlier version of the footrest
rod and bracket, in which the rod popped upward in the bracket toward
the end of the reclining movement. This in no way affects the
functioning of the chair. However, to resolve this noise issue, replace the
footrest rod/bracket with the newer version. Chair with serial numbers
greater than B952411082 already have the newer-version bracket
installed.
