SECTION 9.12:
ADJUSTING DYNAMIC
BACKREST RESISTANCE
The resistance to increasing back angle 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 an air
pump (supplied with every dynamic
back), on the main air valve of the dynamic
mechanism .
To increase the air pressure, pump air into the
valve, to the desired pressure. To decrease
the pressure, press the air release valve on the
pump until the desired pressure is reached.
Warning: The pressure range
is 50-250psi. Never exceed an
air pressure of 250psi in the
uncompressed shock system.
Exceeding the maxium air
pressure of 250lbs/inch could
result in serious injury.
