 Brake shoes and wheel rims must be free of oil and grease.

 Brakes lose effectiveness when wet. Avoid riding in wet weather. If it 

is unavoidable, remember that stopping your A2B Kuo+ will require extra 
distance. Ride more slowly, keep a longer space between yourself and  
other traffic, and begin braking sooner than normal. Failure to take these 
precautions could lead to an accident causing serious injury or death 
and property damage. If you are uncertain about any aspect of the brake 
operation under any condition, ask your A2B dealer or a qualified bicycle 
mechanic. Test the function of your brakes by riding your vehicle in an  
area free from traffic and obstructions prior to every ride.

9.5 Tyres

Check tyres for any damage, cracking, unusual or excessive wear. 
The tyre should be properly seated in the rim and the fit of the tyre 
bead in the rim should be periodically checked. Check for foreign 
objects in the tyre tread and that the valve stem is straight in the rim. 

Damaged or worn tyres should be replaced immediately. Take  
your A2B Kuo+ to your A2B dealer or a qualified bicycle mechanic  
to repair and/or replace your tyres if necessary. In the unlikely  
event of having a flat tyre you need to know the correct procedure 
for removing and re-installing the front or rear wheel.

 If you are uncertain about any aspect of the assembly and   

adjustment of your A2B Kuo+, ask your A2B dealer or a qualified 
bicycle mechanic.

Have your Kuo+ serviced by your A2B dealer at least once a year.

9.1 Wheels

The front and rear wheels should be centred in the fork and frame. 
Wheels should be checked regularly for proper spoke tension and 
rim alignment. DO NOT ride your A2B Kuo+ if it has broken or   
missing spokes. Wheels should rotate smoothly without wobbling 
from side-to-side or up-and-down.

9.2 Hub bearings

Check the hub bearing adjustment periodically by lifting the wheel 
off the ground and spinning it and try to move the rim from side to 
side between the fork or frame. No lateral movement should occur. 
If you detect lateral movement in either wheel, the hub bearings 
must be adjusted or replaced.

9.3 Wheel rims

The rims must be smooth, without cracks, bulges or flat spots. Take 
your A2B Kuo+ to your A2B dealer or a qualified bicycle mechanic 
to repair and/or adjust your wheels if necessary.

9.4 Drive chain

Your A2B Kuo+ has a high quality chain that needs to be cleaned and 
lubricated regularly with bicycle industry approved synthetic lubricant.
