The shock absorber by definition is a hydraulic device used to dampen
suspension/body movement. The road surface irregularities or roughness is
compensated for by the shock absorber. The Roadmaster raised rail chassis
incorporates a "Gas Magnum" shock in the design of the exclusive, air glide
suspension system. This shock absorber is a telescopic, monotubed unit filled
with nitrogen gas and hydraulic oil. The result of the mixture is uninterrupted
damping for the smallest of wheel deflection.
By design, a self-lubricating seal is used which will allow approximately
10% of the total oil capacity to pass onto the piston rod. The gradual process
of oil loss does not affect the performance of the shock absorber during the
service life. This process will be evident after a long period of service, by an
oil film on the body of the shock absorber. The appearance of a coating or
film on the body or rod is called "Misting" and is completely normal. It is an
indication that the shock is functioning normally.
The road holding, handling, balance and braking characteristics all can be
contributed to the shock absorber. A visual check or inspection is recommended
for obvious damage. The key check will be driving; any noticeable changes
in the ride of the motorhome, a lean in the motorhome or excessive bouncing
may be caused by a worn shock. The operating conditions for which the
shock absorber must endure will determine the life span.
The three point leveling system features a multiple warning system with
flashing lights and a bong alarm to alert you of the jack position. The system
also features a remote control location from the driver seat. The torsion stress is
significantly reduced during proper operating procedures. Damage resulting
from improper procedures can range from windshield damage to entry doors
jamming.
The model 22.5A J-II leveling system pump is located curbside front with
easy access from the generator door. The valve assembly manifold is mount-
ed on the the pump motor, providing easy access to the manual retract
valves. The system is designed to be self bleeding in the event any com-
ponent of the hydraulics has been removed or repaired. Fully extend and
retract each jack twice. The remote rocker switches will operate with a
minimum of 7.5 Volt DC. Optimum requirements for operating the system
are voltages above 9.6 Volt DC.
NOTE: The leveling system jacks are not designed for use in
changing tires. This can cause problems with the suspension
system, frame alignment and/or cause damage to the wind-
shield.
