The safest way to operate the chair is on level floors that are free of obstacles.
Whenever possible use a ramp to enter or exit a facility. Keeping your hands
on the push rims will allow you to maintain maximum balance. Do not try to
force yourself over an obstruction by propulsion and never use the sides of a
doorway to pull yourself through a passageway.

Do not lean over the side of your wheelchair since such an action may cause
you to lose balance and fall. (See Figure 2.1)
2.3 Negotiating Inclines
2.3.1 Never turn on a hill due to the danger of tipping.
2.3.2 When assisting, go straight up a slope. If user needs to go down
midway, walk backwards until user is on level ground. (See Figures 2.2
and 2.3)
2.3.3 Avoid stopping on an incline; it can potentially cause you to lose
control of the chair.

cause it to seize up, causing you to lose control or fall out of the chair.
2.3.5 Whenever possible, utilize help from an assistant/attendant while
