Checking the chain tension

9.29
Warning
Danger of accidents Danger caused by incorrect chain tension.
If the chain tension is too high, the components of the secondary power train (chain, engine sprocket, rear sprocket, bearings in
transmission and rear wheel eccentric element) are under additional load. Apart from premature wear, in extreme transmission
output shaft or the drive chain may snap. Conversely, if the chain is too loose it may jump off the engine and rear sprockets,
causing the rear wheel to lock up or even leading to engine damage. Check for correct chain tension and adjust if necessary.
Clean the chain regularly and then treat with chain spray.
