2.7 Replacing a fork
Replace the fork as follows:
•
Remove the wheel from the fork; see 'Replacing a wheel'.
•
Remove screw (A) with a Phillips screwdriver.
•
Remove cap (B).
•
Loosen bolt (C) using a 19 mm box spanner and prevent nut (D)
from moving with a 19 mm ring spanner.
•
Take fork (E) out of the frame.
Take care not to lose the washers (F).
Mount the fork in the reverse order.
Use a locknut M12 Precote 80. The small height of the locknut
allows to insert the hex bolt top to bottom and fasten the locknut
from the bottom side. Use a torque of 70 to 80 Nm to fix the nut.
Attention:
The locknut may not be used again - use a new one when replacing.
2.8 Seat adjustment precautions
Optimizing the different functions in the wheelchair can lead to some limitations in the tilt range. In this case the
tilt in combination with the lowest seat height can limit the possible degree of tilt. This depends on the Centre of
Gravity position of the seating system and the seat depth.
The bigger the seat depth and/or the center of gravity position going to the rear, the bigger the limit of the tilt
angle. If an interference should appear then this can be solved by:
Decreasing the seat depth
Positioning the center of gravity forward
Increase the seat height
2.9 Cleaning Removing dry dirt
Upholstery, metal parts and frame parts can usually be cleaned easily with a dry soft cloth.
Removing mud and/or other wet dirt
Parts that are soiled with wet dirt can best be cleaned by first wiping the dirty parts with a wet sponge and then
wiping them dry with a dry soft cloth.
Upholstery
Cleaning with a damp cloth and household soap. After removing the dirt the cleaned parts should be wiped dry
with a soft dry cloth.
Never use abrasive or aggressive cleansers. They may damage the wheelchair.
Also do not use organic solvents such as thinner, dry-cleaning naphtha, or white spirit. Upholstery: do not dry
clean, iron or spin dry.
