Instructions for use (please refer to imagery as well):
When you receive the pump basic instructions are included. However, if you've never used one of these pumps before it can cause some head scratching. Therefore, we have included these detailed instructions to help you out. We've also included hand labelled diagrams, which are visible in the product imagery above.  

To alter between Presta and Schrader fittings you first have to unscrew the black cap counter-clockwise. This is on tight and requires a little strength to loosen.

Once the cap is off lift up the pump lever arm. This helps to push out the main rubber seal. Pull this rubber out completely (it is stubborn), followed by the small valve stem depressor (this can be tapped out gently, but be mindful of a small plastic ring and small rubber seal falling out with it). It is best to do this on a well lit table or flat surface.

Once the parts are out the main rubber seal and valve stem depressor can be switched around to suit the valve type. Note: the holes on each side of the main rubber seal are different diameters to accommodate for the valve type required. Please refer to the diagrams. 

To reassemble ensure the small rubber seal and small plastic ring are replaced first into the small hole at the bottom of the pump opening (if of course they did fall out when you removed the valve stem depressor). The small rubber seal goes in first, followed by the small plastic cap with its 4 small feet facing downwards onto the small rubber seal. These need to sit flush and cannot be wonky - use a cocktail stick or similar to help seat them correctly.

Next replace the valve stem depressor and main rubber seal. This is easier to do when the two parts are joined instead of separated. Make sure the valve stem depressor goes in first followed by the main rubber seal. This is easier to do when the lever arm is in the downwards position.
Finally screw the cap back on.
 

To use:
Ensure the pump lever arm is in the down position. Gently press the pump opening down onto the valve until it is firmly in position (on a presta valve the little nut on top needs to be slackened off before applying the pump). Once the pump is firmly in place over the valve lift up the lever arm to lock it in place.

Start pumping. 

To remove the pump push the lever down and gently lift the pump off the valve. Remember to tighten the nut on your presta valve to lock.
