WARNING
●As a manufacturer of powered wheelchairs, KARMA endeavors to supply
a wide variety of powered wheelchairs to meet the many needs of the
user. However, the responsibility of final selection of the type of powered
wheelchair to be used by an individual rests solely with the user and
his/her healthcare professional capable of making such a selection.
KARMA strongly recommends consulting a certified rehab technology
supplier or assistive technology professional.
It is the responsibility of the Durable Medical Equipment (DME) Dealer,
therapists and other healthcare professionals to determine if a seat
positioning strap is required to ensure the safe operation of this equipment
by the user. Serious injury can occur in the event of a fall from a powered
wheelchair.

II
Operating Information
●Performance adjustments should ONLY be made by professionals of the
healthcare field or persons fully conversant with this process and the driver's
capabilities. Incorrect settings could cause injury to the driver or bystanders and
damage to the powered wheelchair and surrounding property.
●To determine and establish your particular safety limits, practice bending, reaching,
mounting and dismounting activities in several combinations in the presence of a
qualified healthcare professional BEFORE attempting active use of the powered
wheelchair.
●For individuals with balance problems, practice mounting and dismounting
activities WITH AN ASSISTANT in the presence of a qualified healthcare
professional.
●If so equipped, DO NOT operate the wheelchair without anti-tippers being
installed. Anti-tippers MUST BE attached at all times
●DO NOT attempt to reach objects if you have to move forward in the seat or pick
them up from the floor by reaching down between your knees as this may cause
loss of balance.
●DO NOT lean over the back of the chair to reach objects behind you as this may
cause the powered wheelchair to tip over.
●DO NOT shift your weight or sitting position toward the direction you are reaching
as the powered wheelchair may tip over.
●DO NOT use an escalator to move a powered wheelchair between floors. Serious
bodily injury may occur.
●DO NOT operate in car lanes on roads, streets, highways, etc.

●DO NOT attempt to ride over curbs or obstacles. Doing so may cause your
powered wheelchair to turn over and cause bodily harm and/or damage to the
powered wheelchair.
●DO NOT make sharp turns, in forward or reverse, at excessive speeds.
●DO NOT attempt to lift the powered wheelchair by its casings and seat.
●DO NOT attempt to lift the powered wheelchair by any detachable parts. Lifting by
