Weight Limitations
YourZ-Chair isratedfor amaximumweight capacity.Pleaserefer tothespecifications tableforthis limit.
MANDATORY! Stay within the specified weight capacity of your Z-Chair. Exceeding the weight
capacity voids your warranty. Pride will not be held responsible for injuries and/or property damage
resulting from failure to observe weight limitations.
WARNING! Do not carry passengers on your Z-Chair. Carrying passengers on your Z-Chair may
affect the center of gravity, resulting in a tip or a fall.
Tire Inflation
Ifyour Z-Chairisequippedwith pneumatictires,youshould check orhavethe air pressurecheckedat least onceaweek.
Properinflationpressureswillprolongthelifeofyourtiresandhelpensurethesmoothoperationofyour Z-Chair.
WARNING! It is important that the psi/bar/kPa air pressure rating indicated on each tire be maintained
in pneumatic tires at all times. Do not underinflate or overinflate your tires. Low pressure may
result in loss of control, and overinflated tires may burst. Failure to maintain the psi/bar/kPa air
pressure rating indicated on the pneumatic tires at all times may result in tire and/or wheel failure.
WARNING! Inflate your Z-Chair drive tires from a regulated air source with an available pressure
gauge. Inflating your tires from an unregulated air source could overinflate them, resulting in a
burst tire.
NOTE: If the tires on your travel chair list the psi rating only, use the following conversion formulas to find
the bar or kPa rating: bar = psi x 0.06895; kPa = psi x 6.89476.

WARNING! When on any sort of an incline or decline, never place the Z-Chair in freewheel
mode while seated on it or standing next to it.
WARNING! When climbing an incline, do not zigzag or drive at an angle up the face of
the incline. Drive your Z-Chair straight up the incline. This greatly reduces the possibility
of a tip or a fall. Always exercise extreme caution when negotiating an incline.
WARNING! You should not travel up or down a potentially hazardous incline (i.e., areas
covered with snow, ice, cut grass, or wet leaves).
WARNING! Never travel down an incline backwards. Doing so may cause the Z-Chair
to tip. Always exercise extreme caution when negotiating an incline.

II. SAFETY
WARNING! If your Z-Chair is equipped with a reclining seatback, do not attempt to negotiate
inclines with the seat in a reclined position. Do not attempt to negotiate obstacles with the seat
in a reclined position unless an attendant is present to help stabilize the chair. Failure to heed
could result in the Z-Chair tipping over.
WARNING! Even though your Z-Chair is capable of climbing slopes greater than those illustrated
in figure 1, do not, under any circumstances, exceed the incline guidelines or any other
specifications presented in this manual. Doing so could cause instability in your Z-Chair.
Priderecommendsthat themaximumslopeofaninclineyouattempttosafelyascend ordescendonyourZ-Chairdoesnot
