Maintenance
replacing the wheels
Important!
Please observe the technical data.
Wheels that have a different diameter can change the riding properties and, in
some cases, possibly endanger the user. do not use wheels that cannot be
perfectly mounted. never mount wheels that are larger than the product’s
original wheels.
Wheels wear out. This wear and tear results from many factors, for example the ground, the
user’s size and weight, the weather conditions, the material of the wheels and their durability. It
is thus necessary to replace them from time to time.
• Loosen the axial screws using two size 5 Allen keys.
• Pull out the axel screws and remove the wheel.
• Mount the new wheel and secure it with the axle screws.
After replacing:
do not use if the wheel slides sideways after replacing! Make sure
that all screws are still secure and have not loosened after the first few
minutes of riding. tighten the wheel again to make sure that it rides
smoothly and that no noises are coming from the bearings.
exchanging the ball bearings
• Remove the wheels as previously described (page 24).
• Push out a bearing by applying pressure to the spacer using a hexagon socket screw key and
remove the spacer.
• Push out the other bearing by applying pressure using a hexagon socket screw key.
• Push a new bearing into place. Turn over the wheel, insert the spacer and then push a second
new bearing into place.
• Reattach and secure the wheels.
