It is strongly recommended that a cahin solvent be used to keep the chain clean. Excess dirt built
up on the chain will cause excess wear. A chain lubricant and solvent for normal road bikes may
be uaed.
Check the lubrication and tension of the chain at regular intervals. In the middle of its free length
the chain should have a minimum play of 5 mm. See fig 12. When the play in the chain is about
20 mm (<1 inch) the chain must be tightened otherwise it will cause unnormal wear of the chin
and chainwheels. Because of this it is always recommende to keep the chain play as little as
possible. When the chain has become so long that it can no longer be tightened with the chain
adjusters it is worn out and shall be replaced with a new one.
ADJUSTING CHAIN
Remove left and right frame cover.
To adjust the chain the hub nuts should be loosened. Loosening or tightening the nuts on the chain
adjusters will then move the hub and axle forward or backward. Adjust according to above
recommendation. Then tighten the nuts on the hub axle again. See fig 12.
CHAIN REPLACEMENT
Loosen the chain adjusteras much as possible. Dismantle the cahinlock and remove the chain. Put
on a new chain and assemble the chain lock.The spring of the chain lock should be assembled
with the closed end in the movement direction of the chain. Use a pair of tongs for dismantling
and assembling the spring. See fig 13.
Adjust chain adjusters to chainplay according to above. Tighten axle nuts firmly.
Put on frame covers again.
NOTE: At assembly the flywheel has to be parallell with the center line of the frame.
Otherwise the
chain and chainwheels makes a lot of noise and wears out very rapidly.
