CHAIN ½ x 1/8“
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 9. 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.
Loosen the lower chain guard bracket. Remove the rear right chain guard, by undoing the mounting
screw (M5x6.5mm) at the top and unclipping the white guard holder underneath. Move the chain guard
backward to remove it. Loosen the front chain guard on right and left hand side.
To adjust the chain the hub nuts should be loosened. Loosening or tightening the nuts on the chain
adjusters then the moves the hub and axle forward or backward. Then tighten the nuts on the hub axle
again. See fig 9.
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 10.
NOTE:
If the wheel is not parallel to the centre line of the frame, the chain will get caught
on the top f the sprocket and cause noise.
Reassemble in reverse order.
