SOLUTIONSYMPTOM CAUSE
The legrest
subassembly
partially extends
and hits the
bottom rail.
The legrest
does not hold
in the extended
position.
The base connecting rail
(part of the Mechanism
Side Subassembly) is bent
down causing the legrest
subassembly to hit the
Bottom Rail.
Improper legrest cam
setting for user.
Center Extension Spring
is missing from a chaise
style.
Replace the Mechanism Side Subassembly. Refer
to the work instruction for step‑by‑step details if
needed.
Set the adjustable legrest cams to the high
setting. Stand beside the unit, extend the
legrest, lift the mechanism cover and locate the
two adjustment cams toward the front of the
mechanism (one on each side). Turn the cams
forward, toward the front of the unit for maximum
tension. Set both cams to the same position.
Note: The factory setting is in the center position.
For Chaise Styles: Install a center Extension
Spring. Chaise styles include the center extension
spring as a standard component.
Add a center Extension
Spring to a non-chaise
style.
The legrest is

retract.
For Non‑Chaise Styles: Install a center Extension
Spring if the cams, in the high setting, do
not provide enough tension for the user. The
Extension Spring is not a standard component of
non‑chaise styles produced after 06/2007, but
can be added when the high cam setting does not
resolve the symptom.
Adjust the legrest cams for less tension. Stand
beside the unit, extend the legrest, lift the
mechanism cover and locate the two adjustment
cams toward the front of the mechanism (one on
each side). Turn the cams rearward, toward the
back of the unit for minimum tension. Set both
cams to the same position.
Note: The factory setting is in the center position.

Troubleshooting Guide
SOLUTIONSYMPTOM CAUSE
The legrest
is angled, or
leaning when
fully extended.
The back is
difcult to
pre‑recline,
recline, or return
to the upright
position.
Adjustable legrest cams
are in different settings.
Missing legrest cam
on Mechanism Side
Subassembly.
Plastic slide inserts are
loose.
The upholstered units
are positioned too
close together causing
interference and rubbing
on each other.
Set adjustable legrest cams to identical setting.
Stand beside the unit, extend the legrest, lift the
mechanism cover and locate the two adjustment
cams toward the front of the mechanism (one on
each side). Set the cams to the forward position
for maximum tension, to the center position for
average tension, or to the rearward position for
minimum legrest tension.
Replace the Mechanism Side Subassembly.
Verify the plastic slide inserts are installed
properly and push into place if loose
Sofas—Reposition the mechanism to the outside
set of holes on the Bottom Rail(s) to provide more
clearance between the upholstered units. It may
not be necessary to reposition the mechanism on
both (front & rear) Bottom Rails.
Modulars—Extend the length of the ¼‑20 X 1¼"
Truss Head Screw(s) located in the Stud Mount(s)
to provide ample clearance between units for
mechanism operation.
.
Plastic bushing in the
rear seat slide slot, of
the Mechanism Side
Subassembly, is missing.
Friction plate is installed
improperly with locking
tab oriented incorrectly,
inside the slot.
Wing nut tension setting is
too tight for user.
Inspect both the left and right Mechanism Side
Subassembly to verify the bushing is in place.
Replace the Mechanism Side Subassembly if the
plastic bushing is missing
Loosen wing nut until the washer moves freely
and orient friction plate with tab on top of plastic
insert. Tighten wing nut.
Loosen the Wing Nuts. Extend the legrest, reach
under the seat and locate the adjustable tension
wing nuts toward the front of the mechanism
(one on each side). The factory setting for the
tension wing nuts is 7/16" from the wing nut to the
lip of the slide pivot rivet. Adjust both wing nuts
equally.
Never completely tighten or completely loosen the wing
nuts and operate the mechanism.
