USER GUIDE

1. Only insert the cartridge neck side up when you’re ready to use.
2. Always screw on the cartridge holder to make the cartridge connect with the pump head. Never try to screw the cartridge itself into the pump head. Doing so will result in puncture pin damage.
3. When you have inserted the cartridge neck side up and tightened the cartridge holder, never try to undo the cartridge holder without first fully discharging the cartridge.
4. After inflation, squeeze the trigger and fully discharge the remaining CO2 and then, remove the cartridge. You can re-insert the cartridge neck side down to carry.
5. Avoid leaving a partially full cartridge in the pump. This can quickly result in head and trigger seal damage.
6. When using the bracket, mount the pump upright. This will help keep contaminants out of the pump.
7. Use only CO2 cartridges that are specifically designed for use with CO2 bike pumps.
8. Technical Assistance: Refer to the reference on the enclosed instructions sheet.
9. Only use the Ezi Bike Pump for the purpose intended!

Attaching The Mounting Bracket

1. Release the rubber retaining band and unclip the bracket from the pump.
2. Use the included bolt to secure the bracket onto the seat tube bottle cage mount. You'll need a 2.5mm allen key (not included). Alternatively, use the down tube bottle cage mounts. You might consider which position gives you the best leg clearance.
3. Tighten the bolt firmly to secure the mounting bracket.
4. Clip your Ezi Bike Pump back into position and fasten the rubber retaining band.
5. You can also have the bottle cage attached. However, in my experience, this will not work with every bottle cage as clearances differ.

Tubeless Tire Inflation

Although this might not be an efficient use of CO2 cartridges, the Ezi Bike Pump can help out when you don't have access to a suitable compressed air source. I have found that the Ezi Bike Pump rapidly delivers enough CO2 to easily seat my 29 x 2.2 MTB tubeless tire on a tubeless rim. I then top up using a track pump to my desired pressure. This is however, highly dependent on the quality of the seal between the tire bead and rim. Meaning, you can go through several CO2 cartridges trying to get this to work. I get best results when I first paint the tire bead with a one-third dishwash liquid, two-thirds water solution. This assists the initial seal of the tire bead to the rim before you start working the sealant around the tire. A key point here, if you are re-inflating a tire that has already had sealant running in it, make sure the tire valve is pointing upwards (Ezi Bike Pump nozzle facing down as in the demos) and the valve tip is cleaned of any sealant. This is so any sealant caught in the valve is easily blown back into the tire. A downwards facing valve can cause sealant to flow back into the Ezi Bike Pump nozzle and gum up the trigger mechanism.

Internal Icing

I find the discharge of one CO2 cartridge into a bike tire will give plenty enough pressure to ride home on. If you try to run consecutive CO2 cartridges through the pump (that is, one cartridge immediately after the other), ice will build up on the internal pump valve assembly. This can have the effect of holding the valve partially open so any subsequent and immediately used cartridges loaded into the pump will start to discharge before you’ve even pulled the trigger. If this happens, simply give your pump a couple of minutes for the ice to clear and your pump operation will return to normal. Remember, your Ezi Bike Pump is not designed to be used as a primary means of inflation with the use of consecutive cartridges all at once. It will however always do its job for that emergency puncture repair.

A degree of icing is common on all CO2 inflators. If inflating in the rain (or humid conditions) it's also possible that icing can cause a spluttering effect if the discharge nozzle is faced upwards. I found this is easily avoided by directing the pump nozzle sideways or in a down facing position before discharging (like the photo above, included instructions and in the video demo). An up facing nozzle can allow any ice accumulation to fall back into the pump valve assembly, hence the spluttering. Yet, I've even found this issue to be a rare occurrence.

Cartridge Compatibility

Your Ezi Bike Pump will work only with size 16g cartridges both Threaded and Unthreaded. However, I am aware that there is currently a brand of Unthreaded (non threaded) cartridge that can be purchased on this platform that is too short and will not work. The 16g cartridge needs to be of standard length being 88.1 to 88.5mm, like the one included with your Ezi Bike Pump. My experience is that Threaded cartridges (although the thread is irrelevant) are a more consistent size and suggest that these are the better purchase.

Avoiding Leaks

When I have had off-platform customer communications regarding issues of leakage, in all cases it has been due to incorrect use of the pump. The most common being leaving a partially used cartridge in the pump. Please don't do this! It destroys the seals of any CO2 inflator and causes leaks. Discharge any remaining CO2 in the cartridge and remove.

NB: The Ezi Bike Pump is not to be used for self-defence, scaring the neighbor's cat or shooting your dog. Please, let's use it for its intended purpose, a bike pump! :)
