Question about Serfas FMP500 Floor Pump

Open Question

The SERFAS FP 500 head will not stay on the presta valve. Do I need parts. It pops off the valve at about 40 psi. I use the pump for bike tires (110 psi) and also for sports balls, using the needle attached to the tail. Pump is about 5 years old.

Do you have the connection to the tire valve tight? You must have the connector pushed completely down and the locking lever pushed in the down position. Be sure it can not be pulled off of the valve while pumping up the tire.

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.

How do i use the schwinn airdriver 1100 pump


This pump is a bit strange to use. The valve in the filler head is odd in that it controls the flow of air in both direction...which is not a great design in my opinion...but it does allow for use in different filling applications. The trick is getting the pump into its different filling "modes"

For a Schrader bike valve:
1. Make sure the pump is in "tire mode" by blowing into the valve with your mouth. If you then pump the handle you should feel air filling your mouth.
2. Put the "locking lever" in the unlocked position, the unlocked position is when the silver metal lever is parallel to the air hose, or said another way it makes an "L" with the air outlet that goes on the tire air filling stem. To verify this is correct, look in the air outlet and move the lever from locked to un-locked, you will see slight change in the diameter of the outlet.
3. Push the air filler hole over the schrader valve really hard and make sure it is seated all the way down. Close the "locking lever" (silver metal lever should now be perpendicular to the air house and be in line with the air outlet... i.e. point straight out away from the tire filler stem.
4. Pump.

For a Presta bike valve:
1. Make sure the pump is in "tire mode" again.
2. Take off plastic caps off presta valves on bike tire.
3. Unscrew the little nut on the presta stem to allow the tire valve to open when pressure is applied (you can test this by pushing the stem in a little and air should escape, the nut holds the valve closed, so it needs to be loosened).
4. Take the adapter from the locking lever (silver metal lever) on the pump and screw it on the presta valve. The adapter is the brass looking thing. Screw the rubber gasketed side down on the presta valve.
5. Press the air pump tire filler outlet onto the adapter.
6. Close the locking lever to seal the filler head on the adapter.
7. Pump.
8. Unlock the locking lever and pull it off quickly.
9. Unscrew the presta adapter and screw down the presta valve nut but just finger tight.
10. Screw on the plastic cover cap for the presta valve.

To Fill a Ball:
1. Twist the ball pin filler out by rotating the gray plastic tab around until the ball pin filler is pointing straight out (in-line with the air hose).
2. Make sure the pump is in "Ball mode" by again blowing into the filler. Sometimes shaking the filler valve really hard is necessary.
3. Put the filler pin into a ball.
4. Pump.

Hope this helps.

HOW DO I PUT AIR IN A MOUNTAIN BIKE TIRE WITH A PRESTA VALVE WITH A TOPEAK MINI MASTERBLASTER PUMP.


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.

How to put air in the tires the stems are different


Your bike tube has Presta style valves. Automotive style valves are known a schraders. To inflate the tube, you will need either an adapter, presta to schrader or a hand pump that has a head for presta valves. Any bike shop will have one for sale. To fill the presta valve style, remove the black cap(if it is there) You will see little stem with a small knurled nut. Screw the nut all the way up until it stops. Put the pump head over the stem, making sure it is pushed down. Flip up the lever on the pump head, fill to desired pressure 100 to 120psi...yes, that much pressure, it's a road bike. Flip the lever on the pump head down and remove it from the stem. The PSST you will hear is the air from the line on the pump...not the tire. Screws the knurled nut down and replace the black cap. If you do not srew the little nut down and push on the stem you will let the air out of the tire. If you need more help, you can email me @ danklett@yahoo.com and I will send you pictures of the process, or the staff at your local bike shop should be able to show you how.
