Only qualified Skyfold personnel are authorized to perform any type of maintenance and/or
repair work on your Skyfold wall. However, as the owner of a Skyfold wall, you must assume
the basic cleaning responsibilities related to your Skyfold wall.
Warning
➢
Unauthorized work will void the Skyfold warranty, as stated in the warranty
section of this owner’s manual.
Periodic servicing and inspection of certain components of the Skyfold wall must be
performed to ensure that its mechanical performance, acoustic properties and aesthetics
are prolonged and that it operates safely, as originally designed and installed. Contact your
authorized local Skyfold dealer for service as per the maintenance schedule outlined below.
PERIODIC MAINTENANCE
A cycle is defined as follows: the Skyfold wall has completed one ascent and
one descent.
EVERY 500 CYCLES OR 1 YEAR
Wall Height Adjustment (Upper and Lower Limits)
Over time, the lifting cables may stretch. Consequently, the upper (open) position limit and the
lower (closed) position limit may need resetting.
➢
The upper and lower limits must be verified, inspected and adjusted.
Warning
➢
The Skyfold wall should automatically stop once it reaches either of these limits.
If it does not, do not operate the wall. Call your authorized local Skyfold dealer
for service.
Lifting Cables and Rigging Hardware

The lifting cables, drums, bearings, sheaves (pulleys), couplings, tie-offs, and other rigging
hardware must be inspected for wear, alignment and fit.
Lifting Motor Gearbox

Inspection of the lifting motor gearbox
Electromagnetic Brake

Inspection of the electromagnetic brake
EVERY 500 CYCLES OR 1 YEAR
Hydraulic Checking Device (Safety Motor)
The hydraulic checking device assembly includes a manifold, a reservoir, a pressure gauge, a
hydraulic motor, and a sprocket and chain. During normal operation, the gauge pressure should
be 0-100 psi (0-800 kPa) while the wall is ascending and 200-300 psi (15000-2000 kPa) while
the wall is descending.
➢
The hydraulic checking device must be inspected, and its operating pressure verified.
