chain is at the same level. After the base mark on
both sides aligns and adjusts the relaxation of the
chain to 10-20mm, the rear shaft nut should be re-
fixed and the final inspection should be carried out.
Notice
When a new chain is replaced, it is necessary to
check whether the two sprockets are worn or not
and, if necessary, to replace them.
During regular inspection, the chain checks the fol-
lowing conditions:
• Loose pin
• Damaged roller
• Dry, rusty and broken links
• A twisted or bitten link.
• Excessive damage
• Adjust the loose chain
If the above problems occur in the chain, then the
sprocket will be most likely to cause damage to it.
Check the sprocket for the following:
• Over worn gear teeth
• Broken or damaged gear teeth
• Loose sprocket fixing nut.
