Power cord and plug Inspect the power cord and plug for cuts, nicks, or breaks.
Lockout switches Test each switch separately for proper function.
Foot section Inspect for proper slide engagement of the foot section to the foot
yoke casting assembly.
Inspect the Stow and Go® Foot Section (to include the wire forms,
casters, rollers, and mattress deck) for damage, wear, missing parts,
proper function. Repair as needed.
Air system Test the air system functions (air bladders) for proper inflation and
deflation. Also inspect the mattress for punctures, cuts or tears.
Check the air compressor assembly, hose connections, and "O" rings
for signs of leakage.
Electrical compart-
ment covers
Inspect the covers for signs of fluid leakage into the electrical com-
partment.
Foot supports Check the latch/release mechanism for proper operation. Verify
positioning to ensure there is no binding. Ensure the foot support
rotates up to a 85° position. Inspect the foot supports (see “Inspecting
the Foot Supports” on page 6-7). Repair or replace as required.
Calf supports Check the latch/release mechanism for proper operation. Verify free
rotation to ensure there is no binding. When the release handle is
rotated to the right (clockwise), the ball joint should tighten; when
rotated to the left (counterclockwise), the ball joint should loosen.
Repair or replace as required.
Labor grips Check that the labor grips latch properly and are functional.
Make sure that plugs are installed in the holes on the outside of the
labor grip arms.
Headboard Check the headboard appearance and functionality.
Mattress inspection Inspect the ticking for punctures or any other type of compromise.
Inspect the interior of the mattress for any contaminates.
Inspect air bladders (if present) for leaks, and ensure proper air supply
connection.
Overall appearance Touch up the paint where necessary.
Inspect the labels, and replace if necessary.
Check the general aesthetics of the bed.
Observe the symmetry of the bed by viewing it from each corner
while looking toward the opposite corner (i.e., view from left side,
foot end looking toward right side head end). Ensure that the foot and
head are not bent out of alignment.
