you may have a presta valve which is a different compare it to the one on your car lets say if they are the same you imple place the pump nozzle on the tube and open the lever to lock in place is indeed it is presta the have a much smaller size simple open the nozzle and flip the to pieces inside to allow the pump to be presta capable ok also you will need to screw open the presta valve before trying to pump ok if its still alittle frusterating simply bring in the pump to your local bike shop and they will be more than happy to give you the low down on the pump functions ok :) happy riding ok :)

If it's a simple valve model just unscrew the collar and remove the guts.

I have a Serfas airbones and it is not functioning or perhaps I am not using it correctly. How do I use it on a road bike?


I am assuming you are trying to inflate a presta valve.
If that still doesn't work, your pump may need new seals, or is damaged in some way.

I have the BS-1D Serfas bicycle pump - I need a basic instruction manual as I am having difficulty pumping air into my tire- I think I am not locking into the valve correctly.


I can't find the manual for this one, but most pumps lof this kind work like this:

1) push down over the valve (using the large hole for large valves(Shraeder valves like car ones) and small hole for Presta valves (little screw in kind -must be unscrewed to pump). You might have to be fairly firm with it
2) raise the thumb lock lever (opposite the valve) so it points up
3) pump till inflated
4) release thumb lock
5) pull off pump

If that doesn't work, then your pump may be defective.

I just have a hard time figuring out how to inflate my tires with this pump. I assume I should use the smaller connection. Can't make it inflate.

I am disappointed to find that the Serfas website has NO instructions for their pumps or other products, as if it is intuitive for a novice to operate them.

As a customer you should contact them and complain.

I bought a serfas bike pump some time ago and am not sure how to attach it to the tyre. Whether the lever is up or down, it does not attach and slips easily when pumping. I seems wrong. please inform of...


generally you have to put the pump up to the nozzle and have the lever down then put the nozzle in tightly and then pull the lever up. If after several attempts it doesn't work the pump may be broken, as bike pumps generally break easy

How do you remove the attachment for blow up balls?


Hello rm26,
The majority of bike pumps have a lever right behind where the attachments fit in. When lifted so it's in line with the ball-blow-up adapter, this locks the attachment in place. When pushed down so it points along the hose, that unlocks everything and will allow you to pull out the ball-fill needle, and put another adapter in, or use it directly on a bike/car tire. It's a simple fix, but fairly common system. If you've tried that, in rarer cases they'll screw counter-clockwise out, or can be unlocked by a gear, or twist-top knob on top of the pump.
Hope this helps you! -The Chicken

Fix A Flat. Screw the needle valve into the noozle of a can of Fix a Flat. Squirt enough in to inflate to normal pressure, Roll the ball around to coat the inside. Blow the needle valve clear afterwards attached to a bike pump.

How do you inflate a Bicycle tire with the small portable pump? the air is coming from the needle to inflate balls and not from the nozzle. It is a Schwinn small portable bicycle pump.


Usually, the needle used to inflate balls is an attachment to the pump. Is there a lever near the fitting the needle comes out of? Moving the lever 90 degrees from its current position should allow you to pull the needle attachment out. The hole the needle came out of is where the valve stem from your tire goes to pump the tire up. Jam the stem in the hole, crank the lever back to lock it in and pump away. Unlock the lever to release the stem when the tire's inflated and you're golden.

Instructions for a Schwinn Airdriver 1100 pump. How do you use it??? With the metal lever up or down? I can't get it to work either way!


The switchbladenozzles web site is down, but here is the content from the trouble shooting page circa 2008 from archive.org:

(SCHWINN BIKE) PUMP
• Using the SWITHCBLADE pump nozzle (both 5-in-1 and 4-in-1):
EXPLAINING THE INTERNAL SWITCHING MECHANISM
To get best results from your SWITCHBLADE equipped pump, it is helpful to understand how the automatic switching
mechanism works. The internal switch (changing the air from flowing to the hole for bike tires to the needle for
sport balls) senses back pressure from the object you are trying to inflate. When you insert the needle into the
ball, (or put the nozzle on a bike tire valve) the back pressure inside the ball (or tire) flows into the nozzle
and pushes the switching mechanism to shut off the outlet you are not using.

PROBLEM: Air is escaping through the wrong outlet
NOTE: In the case of a new pump/nozzle OR a pump/nozzle that has not been used for a long time, it is possible
excess lubricant used in the manufacturing process and/or dirt have caused the switch to stick in place.
Don NOT attempt to block the outlet you are not using. Common sense tells you to do this, but in fact it will
only create back pressure in the channel you do not want to use and actually further block air from being
directed to the correct outlet.
FIRST SOLUTION
After making sure your nozzle is firmly attached to the tire valve (or in the case of a sport ball, the needle
is firmly and completely inserted into the ball) give three to five quick firm strokes of the pump. Doing this
should create enough back pressure in the nozzle to free up the mechanism and activate the switch.
SECOND SOLUTION
In certain circumstances, the two most common of which are a brand new bicycle inner tube (note: many new inner
tubes actually have NEGATIVE pressure inside, as they have had the air sucked out of them at the factory to make
it easier to put the tube inside the packaging) or a totally flat sport ball, rapid firm pumping may not be
enough to activate the switch. In these cases do the following:
SPORT BALL:
Insert needle is firmly and completely into the ball.
Give the ball a hard squeeze (this will force air up the needle and trigger the internal switch).
