Maintenance

CAUTION

If the frame or other components of the woom ORIGINAL show deformations or
cracks, the woom ORIGINAL must be sent to a repair shop.
9�1 Tyres
Regularly check the tread pattern and condition of the tyres.

Replace worn or damaged tyres immediately!
Check the air pressure before every ride!

TIP

A pressure loss of 1 bar per month is considered normal. If a tyre loses much more
air, the tube is defective and must be repaired or replaced.
The tyres are fitted with car valves and can therefore be filled at any petrol station. Use a
pressure gauge to set the correct tyre pressure. Checking the pressure with your thumb is
not very reliable.
The permissible pressure range is indicated on the tyre sidewalls and must not be exceeded.
The optimum pressure for tyres with inner tubes is 1.8 to 1.9 bar for a body weight of 25 to 50 kg.
9�2 Chain
The chain must be cleaned and lubricated regularly. See Section 8.2 on page 47.
The chain becomes longer with increasing wear. If it wears too much, it can damage the
sprockets. The chain and sprockets must therefore be checked regularly for wear (see Section
10 on page 51).
9�3 Handlebar, headset, fork
The headset is located in the head tube; it connects the fork to the frame and allows easy
turning of the handlebar. When cycling, it is exposed to heavy loads and must therefore be
seated correctly. The woom ORIGINAL must be handed to professionals if the headset or
the handlebar:
wiggles or exhibits backlash,

can no longer be turned easily or is difficult to move.
