Lubricants. These keep your chain and other parts moving extra smoothly. GRIT commonly uses “Tri-Flow” brand
PTFE lubricant on the chain and seat back.
•
Water/snacks. Using the Freedom Chair is a workout! Make sure you stay hydrated and energized. Carry these in a
small bag on you with your other tools. Some bike bags and water-bottle cages work well, too.

Common adjustments
4.2.1
Inflating the wheels
It’s important to keep the tires at the recommended pressure to prevent flats caused by underinflation. Do not overinflate the
tires. On soft, sandy ground, riding with a lower pressure (but still at or above the minimum pressure) will provide more traction.
On pavement, riding with a higher pressure (but still below the maximum pressure) will reduce rolling resistance and make the chair
easier to push. We recommend 45 PSI for balanced performance over all terrains.
4.2.2
Replacing the tubes
Rear wheels
Replacing the tubes on the rear wheels is very similar to replacing the tubes on a bicycle. A Google search or visit to a bike shop
will provide you all of the information you need. This tutorial is also very good:

4.2.3
Chain tension adjustment
The Freedom Chair uses standard bicycle chain. Chain stretch is normal, and you should expect to have to periodically tighten the
chain over the lifetime of your Freedom Chair. Riders have to make this adjustment early on (new chains stretch the most) and
then a couple of times per year, often after heavy use. Your chain is too loose (and needs to be tightened) if you can squeeze it
together more
than
half of an inch (see Figure 4.2) or if you are experiencing a delay in your lever engagement. This video shows
you the full chain-tensioning process: http://support.gogrit.us/knowledge/how-to-videos/tensioning-the-chains .
