PUMPING TYRES
Fig 34. Valves with cover
Presta valve
• Before pumping the tires, identify the type of valve which is located on the tire. This may
be one of the two valves shown in Illustration 34. and 35.
• Presta valve also has an additional small top, which must be loosened before pumping.
• After identifying the valve, prepare the pump designed to valve type
• Most of the new pumps are equipped to service both Presta valve and Schrader. Many of
them let to reverse the tip. Smaller hole is Presta valve, Schrader valve greater. If the pump
does not support Presta, you will need to buy for yourself the „adapter Presta”, which is
available at any bike store.
• At this point, if the wheel is provided with a valve Presta, it will be necessary to unscrew
the top located on the vent. It is a small top, which can be unscrewed with fingers. When
doing this, the top should move upwards. Then valve is considered open.
• Then remove the plastic top from the valve and set it aside in a safe place. It is important
to not lose it, because the valves will get dirt, leading to difficulties in pumping and rapid air
loss.
• Place the nozzle of the pump to the valve and check if it stick properly. If it is needed, push
the pump to the valve to make sure that the air does not escape to the sides.
• If the pump has a lever with clamp at the nozzle, tighten it. If the nozzle of the pump and
valve have a threaded tip, screw them together. As a result, air will be streamed directly to
the inner tube and the nozzle cannot detach from the valve.
• At the beginning of pumping the pressure in tyres should be checked at some points.
Check tire pressure with your thumbs at the end of the tread. If it is possible, make only a
millimetre indentation. It means that the tire has enough air. If necessary, continue pumping.
• After pumping, remove or unscrew the nozzle from the valve outlet while compressing it is
ends by thumb. It is recommended to do this quick enough in order to not lose too much air.
For Presta valve, tighten previously loosened additional small top. Screw the plastic top on
the valve.
