II. SAFETY
Weight Limitations
Yourpower chairisrated foramaximum weightcapacity.Please refertothespecifications tableforthis limit.
WARNING! Exceeding the weight capacity voids your warranty and may result in personal injury
and/or damage to your power chair. 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 power chair. Carrying passengers on your power
chair may result in personal injury and/or property damage.
Tire Inflation
Ifyourpower chairisequippedwith pneumatictires,you shouldcheckor havetheairpressure checkedregularly.Proper
inflationpressureswill prolongthelifeof yourtiresand helpensurethe smoothoperationofyour powerchair.
WARNING! It is important that 35 psi (2.4 bar) tire pressure 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 35 psi (2.4 bar) tire pressure in pneumatic tires at
all times may result in tire and/or wheel failure, causing serious personal injury and/or damage to
your power chair.
WARNING! Inflate your power 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 and/or personal injury.

only. If your power chair starts to move down the incline faster than you anticipated or desired, allow it to come to a
completestopby releasingthe joystick,thenpush thejoystickforward slightlyto ensureasafely controlleddescent.
WARNING! When climbing an incline, do not zigzag or drive at an angle up the face of the incline.
Drive your power 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! When on any sort of an incline or decline, never place the power chair in freewheel
mode while seated on it or standing next to it. Doing so may result in personal injury and/or
damage to your power chair.
WARNING! Never travel down an incline backwards. This may result in personal injury.

II. SAFETY
Figure 1. Maximum Safe Slope (Ascending and Descending)
WARNING! Even though your power 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 power chair,
resulting in personal injury and/or damage to your power chair.
Incompliance withtheAmericans withDisabilitiesActof1990,allhandicap publicaccess rampsare requiredto havea
maximumslope of5°(8.7%).Therefore,Pride recommendsthat themaximum slopeof anincline youattempt tosafely
ascend or descend on your power chair does not exceed 5° (8.7%). See figure 1.
WARNING! Any attempt to climb or descend a slope steeper than 5° (8.7%) may put your power
chair in an unstable position and cause it to tip, resulting in personal injury.
Braking Information
Yourpower chairis equippedwith twopowerfulbrake systems:

ofhigh traction(such aspassing froma grassy areato apaved area– especiallyat highspeedwhile turning),and abrupt
directionalchanges. Highcornering speeds arenot recommended. Ifyou feelthat you maytip overin a corner, reduce
your speed and steering angle (i.e., lessen the sharpness of the turn) to prevent your power chair from tipping.
WARNING! When cornering sharply, reduce your speed. This greatly reduces the possibility of a
tip or fall. To avoid personal injury and/or property damage, always exercise common sense when
cornering.
Public Streets and Roadways
WARNING! You should not operate your power chair on public streets and roadways. Be aware
that it may be difficult for traffic to see you when you are seated on your power chair. Obey all
local pedestrian traffic rules. Wait until your path is clear of traffic, and then proceed with extreme
caution.

injury and/or damage to the power chair may result.
Preventing Unintended Movement
WARNING! If you anticipate being seated in a stationary position for an extended period of time,
turn off the power. This will prevent unexpected motion from inadvertent joystick contact. This
will also eliminate the possibility of unintended chair movement from electromagnetic (EM) sources.
Failure to do so may result in personal injury.

Electromagnetic and Radio Frequency Interference (EMI/RFI)
WARNING! Laboratory tests have shown that electromagnetic and radio frequency waves can
have an adverse affect on the performance of electrically-powered mobility vehicles.
ElectromagneticandRadio Frequency Interference can come from sources suchas cellular phones, mobile two-way
radios(such aswalkie-talkies), radiostations, TVstations, amateurradio (HAM)transmitters, wirelesscomputer links,
microwavesignals, paging transmitters,and medium-range mobiletransceivers used byemergencyvehicles. In some

WARNING! Be aware that cell phones, two-way radios, laptops, and other types of radio transmitters
may cause unintended movement of your electrically-powered mobility vehicle due to EMI.
Exercise caution when using any of these items while operating your mobility vehicle and avoid
coming into close proximity of radio and TV stations.
WARNING! The addition of accessories or components to the electrically-powered mobility vehicle
can increase the susceptibility of the vehicle to EMI. Do not modify your power chair in any way
not authorized by Pride.
WARNING! The electrically-powered mobility vehicle itself can disturb the performance of other
electrical devices located nearby, such as alarm systems.
NOTE: For further information on EMI/RFI, go to the Resource Center on www.pridemobility.com. If unin-
tended motion or brake release occurs, turn your power chair off as soon as it is safe to do so. Call Pride at 800-424-
