Safety Instructions

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 or breaks. Make sure that there are
Lubrication
The chain should be lubricated with light oil at least every month, or after use in wet, muddy,
braking surfaces.
Adjustment and replacement
To adjust the chain:
1. Loosen the rear axle nuts and move the wheel forward to loosen, or backward to tighten.
2. When correctly adjusted, the chain should have approximately 10mm of vertical movement
when checked in the centre between the chainwheel and rear sprocket.
Centre the wheel in the frame and re-tighten the axle nuts after any adjustment.
Bicycles which have a single speed freewheel, generally use a wider chain than derailleur
geared bicycles. These chains can generally be disconnected by way of a special U-shape
of the chain, position the master link side plate, and slip on the U-shaped snap-on plate.
Make sure the open end of the U-shaped plate is trailing as the link approaches the chainwheel
when pedaling forward.
