Possible cause
System pressure too low.
Too high cornering speed.
Too fast air loss due to dam-
aged rim, valve, puncture e.g.
Air pressure too high.
Incorrect convergence.
Driving axes incorrectly set.
Damaged suspension system,
broken spring.
Damaged braking system,
brake blocking, incorrectly
adjusted braking system. Too
frequent and sudden braking.
Long-lasting ride on tires with
low air pressure.
Machine load too high.
Too frequent climbing over
sharp, high obstacles (e.g.
curbs).
Incorrect braking technique.
Too frequent sudden braking.
Damaged braking system.
Technical Support
Solution
Check air pressure. Check the
road tires for proper inflation regu-
larly. Reduce speed when corner-
ing on a hardened surface.
Check rim and valve. Replace
damaged parts.
Check air pressure. Check the
road tires for proper inflation regu-
larly.
Damaged spring leaf on one side
of the suspension. Replace the
springs.
Check the slack in the suspension
system, check the springs. Re-
place damaged or worn parts.
Check the braking system for mal-
functions. Adjust the trailer levers.
Check air pressure regularly.
Check the weight of the load dur-
ing loading.
Control the driving technique.
Check braking system.
Control braking technique.
Damage arises due to excessive
heating of the hub and the result-
ing wheel rims.
