WARNING
●As a manufacturer of powered scooters, KARMA endeavors to supply a

However, the responsibility of final selection of the type of powered
scooter to be used by an individual rests solely with the user and his/her
healthcare professional capable of making such a selection.
DO NOT be transported in vehicles of any kind while in a powered scooter. It is
the position of Karma that users of powered scooters should be transferred
into appropriate seating in vehicles for transportation and apply the restraints
made available by the auto industry. Karma cannot and does not recommend
any powered scooter transportation systems.
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 scooter.

II
Operating Information
●Performance adjustments should ONLY be made by a dealer, healthcare
professional, or technical personnel. Incorrect settings could cause injury to the
driver or bystanders and damage to the powered scooter 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
scooter.
●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 scooter 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 scooter to tip over.
●DO NOT shift your weight or sitting position toward the direction you are reaching
as the powered scooter may tip over.
●DO NOT use an escalator to move a powered scooter between floors. Serious
bodily injury may occur.
●DO NOT operate in car lanes on roads, streets, highways, etc.

powered scooter.
●DO NOT make sharp turns, in forward or reverse, at excessive speeds.
●DO NOT attempt to lift the powered scooter by its casings and seat.
●DO NOT attempt to lift the powered scooter by any detachable parts. Lifting by

user or damage to the powered scooter. Please hold onto the frame when lifting
your scooter.

surroundings are clear and that the area is safe for travel.

damage that may occur during use which does not comply with applicable federal,

stow the scooter in a separate compartment.
