● Let a second person tilt the wheelchair forward over the drive wheels, until the anti-tipper
wheels prevent it from tipping any farther.
● Swivel the wheels (5) so that they point upward.
● Release the wheels, so that they can swing downwards.
● Adjust the nut (2) using a 22 mm socket wrench so that the wheel forks are not too loose, but
can still rotate freely.
The wheels should swing up to the other side a maximum of one time, before coming to rest
pointed downward.
● Place the wheelchair back on all of its wheels.
● Test the manoeuvrability of the wheelchair.
● Repeat the individual steps if necessary until the coasters are correctly adjusted.
