22.0 Dynamic Back Set Up
DANGER!
•
Never modify your shock system. Modification,
improper service or use of non-Sunrise Medical spare
parts voids the warranty and could cause a
malfunction resulting in serious injury.
•
Follow the maintenance schedule, if the shock
system shows any malfunctions such as losing oil,
making unusual sounds or any part is bent or broken,
cease use of the seating system immediately and
contact Sunrise Medical for assistance.
•
Never try to open or disassemble the shock system.
Opening the shock system could cause serious injury.
Setting the Strength of Resistance & Power of
Return
For maximum performance and comfort, it is necessary
to adjust the strength of resistance and power of return of
the dynamic mechanism, (A). The resistance is adjusted
by varying the air pressure and should be determined by
the user's weight, seating position, seat design and
personal preference.
The air pressure is adjusted with a standard schrader
valve shock system pump (B) on the main air valve of the
dynamic mechanism.
Strong Resistance:
Increasing the Air Pressure
The shock system is more difficult to compress during
use. The seat back feels firmer when pushed against.
•
Attach the pump to the air valve on the back of the
dynamic mechanism (B).
•
Pump air into the valve to increase pressure.
•
Watch the pressure valve dial on the pump to
determine the amount of pressure added.
Weak Resistance:
Decreasing the Air Pressure
Makes the shock system compress more easily. The seat
back feels softer when pushed against.
•
Press button (C) on the pump and keep depressed
until the air pressure resistance achieves required
level.
DANGER!
•
The pressure range is 50-250psi.
•
Never exceed an air pressure of 250psi in the
uncompressed shock system.
•
Exceeding the maximum air pressure of 250lbs/inch
could result in serious injury.
