Frame / Drive Unit Sustainer / Motors - Otto Bock C1000 Service Manual

4.13 Frame / Drive Unit Sustainer / Motors

Disassembling / Replacing the Spring System
The C1000 has two different types of springs: green
and blue.
The green spring has been approved for a maximum
load of 160 kg, the blue spring has been approved for
a maximum load of 200 kg.
The springs are preadjusted to 4.5 cm.
Once you have disassembled everything as described
in the previous sections, you can start disassembling
the frame parts.
Splasher for Driving Wheels
To attach the splashers of the two driving wheels,
first place a metal sheet in the splasher. The metal
sheet and the splasher each contain three bore holes.
Position the holes over one another and put a screw
through the upper hole from behind and secure the
screw with a cap nut.
The springs are located on the side of the drive unit
sustainer, behind the wheels.
Install the springs as shown in the photo. Hold the
spring between the bracket on the drive unit sustainer
and the pre-drilled hole in the oscillating crank. Put a
washer between the screw head and the bracket and
tighten the screw.
A 6 mm Allen wrench and a 13 mm wrench are
required.
The two upper screws of the motor suspension are
used for attaching the splasher.
Loosen and remove the two upper screws, apply the
splasher and reapply the two screws.
Note: Do not forget to secure the wheelchair to
prevent it from slipping or tipping over. Support the
C1000 so that the driving wheels are able to rotate
freely and the chair is unable to slip.
