Owner´s Manual Permobil M400
Driving uphill
You should always drive uphill with great caution.
Avoid sudden evasive maneuvers and never drive so fast that you are unable to
control the wheelchair safely without risks.
m WARNING!
Do not drive uphill on a gradient greater than 8°.
Dynamic stability according to ISO 7176-2 = 6°.
m WARNING!
You should be extremely careful when driving uphill on an uneven surface (for example grass,
gravel, sand, ice and snow). Failure to do so may result in personal injury and/or damage to the
wheelchair.
A raised seat lift/seat angle/back angle changes the center of gravity and increases the risk of tip-
ping. Therefore, use these seat functions only on flat surfaces and always drive with great caution
and at low speed.
