8 Cleaning
Clean the woom OFF regularly so that it remains in good condition and your child is always
safe on the road.
HINT
Do not use a pressure cleaner as this may damage the bearings and attachments.
Never clean the bike with acids, hot oil or liquids containing solvents.
8�1 Frame, handlebar, fork, wheels
Clean these components with warm water, a mild detergent and a soft cloth or sponge.
8�2 Chain, cassette, sprockets
Clean these components with an oily cloth and a brush or with a suitable cleaning agent for
chains. The chain needs to be lubricated at regular intervals. Do not use too much oil and
remove excess oil with a cloth.
ATTENTION
If you use oil spray, make sure that no oil gets on the brake pads!
CAUTION
If oil gets on the brake pads, they must be replaced!
8�3 Brakes
If the brakes are very dirty, you can clean them with warm water and detergent. Use a suitable
brake cleaner to clean the brake discs. Never use cleaning agents containing oil.
9 Maintenance
CAUTION
If the frame or other components of the woom OFF show deformations or cracks, the
woom OFF 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 51.
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 55).
9�3 Handlebar, headset, fork
The headset is located in the head tube; it connects the fork to the frame and allows easy turn-
ing of the handlebar. When cycling, it is exposed to heavy loads and must therefore be seated
correctly. The woom OFF 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
