WARNING:
Removing the batteries can lead to a change of the center
point of gravity. The result may be that the chair flips
backwards without the weight of the batteries.
Sunrise Medical advises to:
• Put an obstacle behind the chair to secure the situation. This
can be a chest, or a chair, or etc.
• Try to lift the battery slightly first to check the effect of taking
out the weight.
• Only remove the batteries while the chair is on the ground.
• Do not remove the batteries while the chair is on a lift table or
on any other elevated surface.
