cover with the chain sprocket cover nut.
Note:
Only tighten the chain sprocket cover nut

WARNING!
IF YOU TRY TO ROTATE THE CHAIN TENSIONING SCREW
WHILST THE CHAIN SPROCKET COVER NUT IS TIGHT, IT WILL RESULT IN
THE CHAIN NOT LOOSENING AND POSSIBLE DAMAGE TO THE CHAIN
TENSIONING SCREW AND THE CHAIN TENSIONING PIN.
Tensioning the Chain
1. Using supplied spanner loosen the chain sprocket
cover nut.
Do not remove chain sprocket
cover.
2. Adjust the chain tension with the 3mm hex key.
Turning
CLOCKWISE
increases the chain tension,
turning it
COUNTER-CLOCKWISE
decreases the
chain tension.
For the correct chain tension, firmly pull up on the
chain at the middle of the top of the exposed guide
bar. When the chain is pulled up to its highest point,
the bottom tip of the links should only just stay in
the track [middle of the guide bar].
3. Once the correct tension has been achieved,
tighten the chain sprocket cover nut to lock the
chain bar in place.
Note:
Chains lengthen slightly as the link pins set
into place. They set into place from the load applied
to the chain, this process continues throughout the life of all chains as they
gradually wear from use.
