parts of the legrest while elevating or lowering the legrest. CAUTION: Legrests are not to be used for lifting or
carrying the wheelchair with an occupant.
To steer the chair simply move the joystick or knob in the desired direction. The further forward you push it, the
faster the wheelchair will travel. The knob regulates the power and speed. When it is released, the brakes go on
automatically and the wheelchair is stationary. It is important that you stop the whhelchair before you change
direction from forward to reverse. Always turn off the wheelchair before stepping out of it. Look ahead while you
drive, not at the controls. Remember that only with practice will you become a competent driver.
Joystick: Your F35 is controlled by a joystick, which determines speed and direction. The more forward the joystick
is pushed, the faster the wheelchair travels. When the joystick returns to its central position, the brakes enter into
operation automatically. On flat ground, braking distance is equal to the length of the wheelchair. On a hill it may be
a Iittle more, and you will note how the brakes go on automatically when the wheelchair is almost stationary.
Other controls (Fig. 7)
On/off button: This connects or disconnects the entire electronic system, which supplies energy
to the motors. Do not use this button to stop the chair except in case of emergency, in doing so
may damage the wheelchair.
Battery Gauge: This indicates that the wheelchair is under power. It also indicates any fault there
may be in functioning. The number of lights flashing indicates the fault type. (See "Battery Gauge"
in this manual.)
Speed indicator: This indicates the maximum speed set for the wheelchair. There are five speeds
predefined. The first is the lowest, the last is the highest.
Speed decrease button: Decrease the maximum speed setting
Speed increase button: Increase the maximum speed setting

Battery Gauge
- If it remains lit, this means that everything is OK. It flashes to indicate any fault that may have arisen. Slow and
stable flashing means the batteries need charging.
- If it flashes once every 2.5 seconds, this means that the control system has deactivated particularly if the
wheelchair has not been used for a certain period of time. To reactivate it, turn off the system and then turn it on
again.
- If the fault indicator flashes rapidly, this indicates that there is a fault. Turn off the system. Check the state of the
batteries and the connections, and turn on the system again. If the flashing continues, the number of bars
flashing will indicate the location of the fault.
If the number of bars on is 1: The batteries need charging, or are badly connected.
If the number of bars on is 2: The left motor is improperly connected.
If the number of bars on is 3: Electrical fault in the left motor.
If the number of bars on is 4: The right motor is improperly connected.
If the number of bars on is 5: Electrical fault in the right motor.
If the number of bars on is 6: The battery charger is plugged in.
If the number of bars on is 7: Fault in the control.
If the number of bars on is 8: Fault in the control systmem. Make sure the control system connections are
secure.
If the number of bars on is 9: Fault in the electromagnetic brake.
If the number of bars on is 10: Excess voltage.
Safety switch: In the unlikely event that the wheelchair is overloaded, there are safety devices built into the electronic
system. The power of the motor will be automatically reduced. This device cuts in only in extreme circumstances,
such as repeated climbing of steep hills in very high ambient temperatures. The button on the side of the battery
box immediately trips, and the wheelchair stops. This safety switch may function again when the button is again
pressed. Within a few seconds you will be able to resume normal speed.
