CHAIN 1/2" x 1/8"
Check at regular intervals that the chain is correctly tensioned and sufficiently lubricated. At the mid-
point of its free length the chain should have free play of minimum 5 mm, see fig. At 20 mm play the
chain should be tightened. Otherwise abnormal wear will occur both on the chain and on the chain
wheel. On account of this it is recommended that the amount of play is kept as close to the minimum as
possible. When the chain has become so long that it can no longer be tightened with the chain tightener
it should be changed for a new one.
Slacken the lower chain guard attachment. Remove the screws on the upper side of the guards. The
guards should first be slid back a little, then they can be completely removed.
When adjusting the chain slacken the axle nuts on the brake wheel. The hub and axle can then be slid
back and forth by slackening or tightening the nuts on the chain tightener. Afterwards retighten the nuts
on the hub axle.
The hold down springs on the chain connecting links must be assembled with the closed end in the
direction of motion of the chain. Pliers can be used to remove and assemble the hold down springs, see
fig.
NB The wheel must be aligned parallel to the frame’s centre line. Otherwise noise can arise from the
chain as it can have a tendency to get caught on the cog teeth.
Then reassemble according to the above but in reverse order.
