Chain 1/2“ x 1/8“

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 (3) of 10 mm (1/4

inch). See Fig: Chain adjustments. When the play in

the chain is about 20 mm (3/4 inch) the chain must

be tightened. Otherwise it will cause abnormal wear

of the chain and sprockets. Therefore it is always

recommended to keep the chain play as small as

possible. Loosen the axle nut (2) on both sides and

tense the chain with the chain adjuster (1) when

needed.

When the chain has become so long that it can no

longer be tightened with the chain adjusters it is worn

out and should be replaced with a new one.

To adjust or replace the chain, remove covers if

required.

To adjust the chain the axle nuts (2) should be

loosened. Loosening or tightening the nuts on the

chain adjusters (1) will then move the hub and axle

forward or backward. Then tighten the nuts on the

hub axle again. See Fig: Chain adjustments.

To replace the chain, loosen the chain adjusters as

much as possible. Dismantle the chain lock (6) and

remove the chain. Use pliers to both release the lock

washer and mount it again (4). 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 (5) of the chain. See Fig: Chain

replacement.

NOTE!

At assembly the ﬂywheel has to be parallell with

the centerline of the frame. Otherwise the chain and

sprockets make a lot of noise and wear out rapidly.

Then assemble the removed parts as above but in

reverse order.
