Drive Chain Maintenance
The service life of the chain greatly depends on the maintenance. Refer to the following contents:
Chain inspection for defects
■ Clean the chain
● Rinse large stains with a gentle water beam.
● Remove lubricant residue wit chain detergent.
● Spray chain lubricating spray after drying.
■ Replace the chain
■ Check the rubber cushion and chain guide.
If the chain is too tight, it will accelerate the wear of the
front sprocket, the rear chain disc, the chain guide, the
rubber cushion and the tensioner, and it may be broken or
damaged locally.
■ Loose chain:
The loose chain may fall off the chain disc; the chain guide
can prevent the chain from falling off, provided that the
chain guide is intact; the falling chain may damage the chain
guide.
Regular inspection or replacement of tensioner and rubber
cushion can prevent chain wear and detaching.
