DETAILED MAINTENANCE

CHAIN

Inspection

The chain must be kept clean, rust free and frequently
lubricated in order to extend its life as long as possible. It
will require replacement if it stretches, breaks, or causes
inefficient gear shifting. Make sure that there are no stiff
links, they must all move freely.

Lubrication

The chain should be lubricated with light oil at least every
month, or after use in wet, muddy, or dusty conditions. Take
care to wipe off excess oil, and not to get oil on the tires or
rim braking surfaces.

Adjustment and Replacement

On derailleur geared bicycles the rear derailleur automatically
tensions the chain. To adjust the chain on single speed
freewheel, coaster hub braked or 3-speed hub geared
bicycles:
1. Loosen the rear axle nuts (and coaster brake arm clip if
fitted) and move the wheel forward to loosen, or backward
to tighten in the frame.
2. When correctly adjusted, the chain should have
approximately 10 mm of vertical movement when checked
in the center between the chainwheel and rear sprocket.
Center the wheel in the frame and retighten the axle nuts
after any adjustment.
