Setting the Power of Return
The power of return controls the rate at which the
shock system decompresses or rebounds. The
amount of return strength needed depends on the
user’s weight, the spring rate which is set by the air
pressure, the amount of use, the sitting style and
personal preferences.
The best way to adjust the return strength is to
decrease it completely by turning the red adjuster
wheel (D) clockwise (labelled slow) and test by
placing the user in the seat. Increase the damping by
slowly turning the wheel counter clockwise (labelled
fast) until the user feels comfortable and safe without
the suspension kicking the user too far forward.
Disengaging the Mechanism
Occasionally at meal times etc it is necessary to
disengage the dynamic mechanism. To do this:
•
Lock the system by switching the lever from the
“ open “ to “locked” position on the lever on the
shock system.
•
The mechanism should not be left in the ‘locked’
position as part of normal use. You should ensure
the mechanism is returned to the ‘open’ position
once the activity demanding the lock out has
been completed.
Maintenance Schedule:
The rear shock systems need a minimum of maintenance only:
•
Use water and soap only to clean the system - never use a high pressure washer or any water under
pressure to clean the shock system as water may enter the system.
Before every use:
•
Check air pressure (it is normal for the shock system to lose air pressure slightly over time) - Check
to ensure it is appropriately set for your client.
•
Adjust power of return set up to ensure it is set appropriately for your client.

The extensive service of the shock system internals
must only be done by an authorized technician.
WARNING!
Please note that your SR SUNTOUR rear shock is filled with oil and nitrogen. This
makes it impossible to open the rear shock without having the knowledge and special
tools required to carry out this task. Please do not try to open the rear shock for service
issues, this implies a very high risk of getting seriously injured. Besides this you will not
be able to reassemble the shock any more. Opening the shock will void its warranty.
If there is a problem with your rear shock, cease use of your chair immediately and
contact JCM Seating Solutions.
