SOURCE: Bicycle tire pump won't pump.

If you can? unscrew the two pieces of the pump clean and oil it. W/D40 works pretty good.

SOURCE: How do you inflate a Bicycle tire with the small

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.

How do you attach zefal z console to bike?


After a call to the customer service people who were more confused than I was, I figured out how to mount the bracket to the handle bar. Believe it or not the Zefal guys did not have an instruction manual on the product they sell. So here is how it works... You have to run the hard plastic strap around the handle bar and push it into a gap between the plastic nut . It's such a small gap that you will have award time finding it. Once you tighten the plastic nut the strap will advance slowly until the end will come appear on the other side. That's all there is to it. Now why the heck could they not put a picture of this on the box? Perhaps job security for the Zefal guys?

I am buying a bike pump. My Tires Kenda Comfort w/ puncture resistant K-shield 26x1.95 on The Classic Serene 2010. Do they have standard valves or presta valves. Can you recommend a floor pump for me.


Tires don't have valves. TUBES do. Can't you tell by LOOKING at them?

http://en.wikipedia.org/wiki/Schrader_valve#Presta_valves_vs._Schrader_valves

Either way, you should buy a pump that serves both types. Stick with name brand - Blackburn, Park Tool, Topeak. Get on the web and read some reviews.

Do you have step by step instructions on how to use floor pump air 2?


Place the end of the air hose nozzle from the pump on the tire valve.
Flip the lever on the side of the air nozzle straight up to lock the nozzle to the tire valve.
Hold the cylinder in one hand. Grab the end of the pump by its handle.
If the handle flips up, flip it up and turn it sideways and let the handle slip into your palm.
The stem of the handle should be extended between your middle finger and your ring finger.
Pull the handle straight out.
You will hear a slight hiss as the air is pulled into the bottom cylinder
and air is expelled out down the hose at the same time.
Push down on the handle to expel the air into the hose from the bottom of the cylinder.
Continue pushing and pulling up on the handle as you hold the pump in your hands until the tire is firm to the touch.
Remove the air nozzle from the tire valve.
Place a tire-pressure gauge on the valve to check the pressure.
Continue pumping and checking the tire to inflate it to the recommended pressure that is marked on the side of the tire.

I can't get my pump to pump air in my daughters tire. This is my first time using a pump where I have to set the pressure. What do I set the pressure to in order for it to pump the air in the tire?


You don't have to "set the pressure", that knob is just for your own reference.

Most problems of this sort are due to not getting a good seal with the tire nozzle. Here are some steps to help you along.

1. put the bike on a flat surface
2. spin the wheel so the nozzle is facing upward
3. put the pump end on the nozzle with the lever down (this is a common mistake as older pumps had to start with the lever up)
4. Push the end down on the nozzle and pull the lever up
5. If you hear air escaping, then hold the pump end on the nozzle for the first few pumps.
6. pump it up till its a bit hard but be careful you can pop it.

check out the video for a but more info and good luck!

I have a schwinn bicycle pump and i need to know how to use the bike tire part and not the needle part


The needle part for blowing up basketballs and the like simply unscrews from the bike tire part. Depending on the type of tire you have, you might have to get an adapter. If it looks like your car tire stem, it's called a Schraeder valve, and you should be all set. If it is thinner and has a tip that you unscrew, it is called a Presta valve, and you may or may not need an adapter depending on your pump.

Hope this helps.

The pressure gauge on my Topeak Joe Blow Ace floor pump is not working. The pump works fine. How do i take the pump apart and what should I be trying to do to repair?


http://www.ehow.com/how_4779541_inflate-bicycle-tire-presta-valve.html

  1. Rotate the wheel so the valve is resting just above the floor. Remove the valve cap.

  2. Unscrew the locking nut on the valve stem. Quickly press down the stem to loosen the seal. You should hear air escaping when the stem is pushed in--if you do not, loosen the nut and try again.
  3. Press the pump head onto the valve and flip the locking lever to make a seal. You'll hear air escape, but it should stop after you've locked the lever. If air continues to leak out, remove the pump head and reattach it.
  4. Make two pump strokes and listen for air moving into the tire. If the pump handle becomes hard to press down after only a few strokes, or if the pressure gauge elevates extremely quickly, remove the pump head and repeat Step 3.
  5. Inflate the tire to its recommended pressure. Remove the head by unlocking its lever and quickly pulling it off the valve stem. Secure the valve's locking nut and cap.

I can't get my Zefal pump to seal onto my Pestal tires. The pump head constantly pops off. Do I need to return the pump?


If it is a dedicated presta pump, there should be a threaded cap on the head where it attaches to the valve stem - it has a hole through it to allow the stem through. Tighten that stem slightly and it should compress the rubber enough to hold on. But don't tighten too much or it will be hard to get off.

The head holds on with a rubber donut under that cap. By tightening the cap, the donut gets compressed and closes the hole tighter.

I have a Zefal HP frame pump. I'm trying to inflate a tire with a Presta valve. It just won't inflate. It doesn't latch onto the valve and seems to big for the valve body. Is there a diagram available...


Let's hope you didn't force it and snap the plastic point off.

Most Zefal pumps come with a reversible head that can adapt to either Presta or Schreader (like on cars). You unscrew the barrel at the working end of the valve, carefully tap out the rubber cylinder and the plastic internal piece behind it.

Insert the plastic piece in either of two ways. Pointy part Out (for Schrader) or just a round opening Out (for Presta). Rotate the rubber piece correspondingly to show the large opening for Schrader or the smaller opening for Presta and place it inside the valve over the plastic piece. Screw the knurled barrel on tightly.

How do I change to presta


If your pump is not double sided (which the one in the picture looks like) the rubber valve can be reversed very easily by unscrewing the outer cap where you usually insert the valve and turning the little rubber valve around before screwing the outer cap back on.
