The Mark I was designed to be mobile, with the idea that volunteers would wheel it from its storage location to the BEECN site. In practice, this is can be challenging. The inflatable tires can traverse uneven ground to a point, but do not do well in mud. Because of this, and since a fully loaded cache is over 250 lbs., it takes two people to move one of these caches provided the tires are fully inflated. Otherwise, in an actual deployment, volunteers may need to open the cache and carry supplies to the BEECN site. | The Mark I was designed to be mobile, with the idea that volunteers would wheel it from its storage location to the BEECN site.

For underinflated tires, each Mark I cache should include a bike tire inflation pump. If inflating the tire that way does not work, there is a good chance the tube needs replacing or patching. PBEM staff can replace the tube, or provide the needed tools to a BEECN volunteer to do it themselves. | |||
'''Tools and materials needed:''' | |||
* 2x 6" or 8" adjustable wrenches; | |||
* Car jack and jack arm (this is helpful since otherwise you would need to empty the cache and flip it over); | |||
* A bike tire patch kit; | |||
* Exam gloves (this is a messy job). | |||
Use the two wrench to take the wheel off entirely and pull out the tube. Run your fingers inside the tire after the tube is out to make sure there's nothing poking through to puncture the tube you put in. If you buy patching material at a bike shop the easiest to use are the self-adhering patches that come with a bit of sand paper to scrape the area around the hole. | |||
If the tube is replaced, do not throw away the old tube. PBEM will pick it up from you and use it to order a new one from Les Schwab. | |||
