Punctures:
Inner tube punctures can be caused by careless riding over sharp stones,
holes in the road or by hitting curb stones.
In the event of a puncture the tyre should be completely removed. With the inner tube
deflated, push the tyre to the centre of the rim. Carefully hook a tyre lever (not supplied
with the bicycle) under the edge of the tyre and gently lever the tyre bead over the edge
of the rim. Repeat this procedure with a second tyre lever positioned a few inches away
from the first one. It should now be possible to pull the complete side of the tyre off.
Push the valve back through the rim and remove the inner tube. Finally, remove the tyre.
Carefully check the inside of the tyre for sharp objects that may have caused the puncture
i.e. nails/ pins/ thorns ect. These must be removed.
Repair the inner tube using a puncture repair kit - follow the instructions supplied.
To replace the tyre, fit one side of the tyre back onto the rim. Push the valve through the
rim valve hole and feed the inner tube into the tyre. Make sure the inner tube is slightly
inflated and them ‘work’ the tyre back on to the rim using both thumbs.
Slowly inflate the tyre making sure it is sitting squarely and is sealed correctly on the rim.
When fully inflated replace the valve cap.
Saddle:
Adjust for comfort and proper fit.
Never allow the ‘minimum insertion’ mark to
show above the top of the seat tube.
Steering:
The steering of your bicycle should be smooth and easy.
To adjust, loosen the top lock nut and carefully adjust the top bearing cone. Tighten the
lock nut whilst holding the bearing cone steady with the multi-sized spanner.
A tight headset will make steering difficult especially around corners, whereas
loose headset bearings will cause the front wheel to behave erratically. If you have any
doubt about the adjustment of the headset bearings, ask your universal dealer to make
the adjustment.
