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 hub 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 shall be replaced with a new one. 

To  adjust  or  replace  the  chain,  remove  covers  if 
required.

To  adjust  the  chain  the  hub  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 a pair of tongs for dismantling spring. 
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. 
Use  a  pair  of  tongs  for  dismantling  and  assembling 
the spring (4). 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.
