Owner´s Manual Permobil M400
Driving downhill
You should always drive downhill at low speed and with great caution.
Avoid braking suddenly and sudden evasive maneuvers and never drive so fast
that you are unable to control the wheelchair safely without risks.
Safe slope 8°
m WARNING!
Do not drive downhill on a gradient greater than 8°.
Dynamic stability according to ISO 7176-2 = 6°.
m WARNING!
You should be extremely careful when driving downhill 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.
