Shock Absorber Springs (Magic 360 Only); Slope Sensor (Inclinometer) - If Fitted - Sunrise Medical Magic Mobility Extreme X8 Owner's Manual

4.14 Shock absorber springs (Magic 360 only)

The four shock absorber springs are set to factory
default at time of manufacture. These springs can be
adjusted for improved chair performance depending on
user weight (see Figure 4.4). A spanner is located inside
the rear power module cover. Only the shock absorber
springs are adjustable. The rest of the suspension
linkages should remain as supplied.
The amount of preload required on the shocks mainly
depends on user weight and his/her positioning on the
seat. Refer to the table on the right for approximate
values based on user weight. Small protruding 'pips' are
moulded into the front and rear side plastic covers and
the leading and trailing arms. If these 'pips' line up when
the user is seated, then the shock preload should be
appropriate (see Figure 4.4).

4.15 Slope sensor (inclinometer) – if fitted
The slope sensor option enables the chair to be aware
of its backrest angle relative to the horizon. This includes
the accumulation of backrest recline, seating tilt and
ground incline put together. The slope sensor uses
this information to minimise the chance of the chair
becoming unstable due to body weight being too far
back.
Backrest angle inhibits
The inhibit/s depend on the backrest angle are
as follows:
BACKREST
ANGLE
0° - 30°
31° - 50°
> 51°
Seat raise inhibits
A further inhibit may activate depending upon the seat
lift height. When the seat is lifted above a certain height
the LCD joystick module will display an orange turtle. If
you have a LED joystick module its speed indicator lights
will flash. These indicate the following inhibits because of
the seat elevation:
• Speed
• Tilt back
• Recline back
• Troubleshooting.
If your chair has a slope sensor and a function does not
seem to be operating do the following:
• Drive the lift function downwards until it stops in the
home position
• Drive the tilt function forward until it stops in the
home position
• Drive the recline function forward until it stops in the
home position
• If your chair is still inhibited please refer to Section 8
Common Troubleshooting.
