The Lifter - Invacare Typhoon II Operating Manual

The Lifter

The electric lifter is operated via the remote. Please see chapter "Operating the electric
adjustment options" on page 45.
Information regarding operation of the lifter at temperatures of less than 0 °C
Our wheelchairs are fitted with safety mechanisms that prevent capacity overload of the
electronic components. At operating temperatures below freezing point this can, in particular,
lead to the lifter actuator being shut down after approx. 1 second operating time.
The lifter can be raised or lowered gradually by repeatedly operating the joystick. In many cases
this generates sufficient heat for the actuator to operate as normal.
Please note – Speed restriction
The lifter is equipped with sensors that reduce the drive speed of the wheelchair as soon as the
lifter is raised or lowered above a certain point.
This is in order to guarantee the tilt stability of the wheelchair or in order to avoid damage to the
legrests.
When speed restriction is activated an appropriate blinking code is displayed on the remote.
Please see chapter "ON/OFF diode (status display)" on page 40 and chapter "Error codes
and diagnostic codes" on page 49.
In order to revert to normal drive speed move the lifter to drive height: Raise the lifter slowly if the
lifter has been lowered. If the lifter has been raised, lower the lifter until the status display stops
blinking.
