The air valve is located under a cover on the
head of the left shock absorber. Screw off the
cover.
Figure 57: Screw caps in different designs
Screw a high-pressure pump onto the valve.
Pump the suspension fork up to the desired
pressure. Never exceed the recommended
maximum air pressure. Comply with the values
of the filling pressure table.
Remove the high-pressure pump.

Measure the distance between the crown and
the dust wiper of the fork. This distance is the
total deflection of the fork.
Push a temporarily attached cable tie
downward against the dust wiper of the fork.
Put on your usual bicycling clothing, including
luggage.
Sit on the pedelec in your usual riding position
and support yourself (e.g. against a wall or
tree).

6.3.5.3 Adjusting the steel suspension fork
Only applies to pedelecs with this equipment
You can adjust the fork by tensioning the spring to
the rider's weight and their preferred riding style.
It is not the coil spring hardness which is adjusted;
it is its pre-tensioning. This reduces the fork's
negative deflection when the rider sits on the
pedelec.
