WARNING
Electronic safety circuits
Permobil's products are fitted with safety circuits. Inhibit circuits prevent the
chair from driving under certain conditions. Speed reduction circuits limit the
wheelchair's maximum speed under certain circumstances. Limit circuits limit
the wheelchair's functions in certain circumstances. Overload protection cir-
cuits switch the wheelchair off if it is overloaded. The user should immediately
stop using the wheelchair and contact an authorised service engineer or
Permobil if he or she suspects that any of these circuits is no longer working.
Any attempt to modify the safety circuits will result in unsafe use of the wheel-
chair and may lead to the chair being unstable or uncontrollable. Such use may
also invalidate the warranty.
Replacing the batteries and fuses
The main fuse must always be switched off when fuses and batteries are
replaced.
Be careful when using metal objects when working with batteries. A short-circuit
can easily cause an explosion. Always use safety gloves and safety goggles.
Filling tires with air
Check at regular intervals that the wheelchair's tires have the correct tire pressure.
The incorrect tire pressure may result in lower stability and maneuverability.
The correct tire pressure is 200 kPa (2 bar). Note that overfilling entails a risk
of explosion.
