Service Manual JOKER 8
FORK ANGLE 1
system with spirit level
SERVICE MANUAL
When adjusting the fork angle avoid:
Working on ring
A1
and
A2
(fork) together form the beginning
–
this does not give any precise point of reference (as ring
A1
does in one
any position that you can change if not correct).
Thinking that the front wheel must be orientated as when driving the wheelchair (the fork is part of the adjustment).
Keeping the nut
B
too loose while finding the correct angle.
Directionality check.
After adjustment, the wheelchair has to be tested to verify if it goes straight.
See also sheet DIRECTIONALITY.
Check both casters are touching the ground, if not, adjust their height.
If the wheelchair turns right or left, it means that you need to correct the adjustment.
If it turns right:
the right fork is tilted inward (internal) or the left fork is titled outward (external).
If it turns left:
the left fork is tilted inward or the right fork is titled outward.
Check which of the two to adjust.
The adjustment will be really of minimum entity.
The necessary rotation of either
A1
or
A2
(fork) is tiny.
Loosen the nut
B
as little as necessary.
Proceed with the adjustment making the bubble slightly move:
- inwardly with respect to the wheelchair if the fork is external;
- outwardly with respect of the wheelchair if the fork is internal
The bubble does not necessarily be perfectly concentric with the circle of the spirt level.
It is enough that it is within the circle or even adjacent.
The spirit level is, at origin, glued to the axle, therefore, there is a minimum tolerance while centring it.
After adjustment, the wheelchair has to go straight.
