5.8 Obstacles and curbs
1.
Never descend a curb backwards.
2.
Do not attempt to climb or descend a series of steps or use on escalators. It
is unsafe to do so and could cause personal injury or damage the chair. This
wheelchair has only been designed to climb a single step or curb.
3.
We recommend that users with upper trunk instability wear further
personalized restraint systems to keep the upright body position during
descending or ascending ramps, curbs, or obstacles.
Curb climbing
Always approach a curb at 90° (Fig. 5.1).
1.
Approach the curb or step, head on at a 90° angle.
2.
Drive forward slowly and steadily.
3.
Stop the chair as soon as the caster wheels touch the curb.
4.
Apply suffi cient power to the motors to lift the front of the chair up onto
the curb or step and then apply slightly more power until the drive wheels
climb the curb or step smoothly.
5.
As far as possible, keep the joystick in the straight forward position.
The maximum obstacle or curb climbing height is 2.4-in (60 mm) for Group 3 and
3-in (75 mm) for Group 4.
The approach speed and process can vary depending on your wheelchair drive
type and caster wheel choice.
Descending the curb
Move the chair slowly and carefully in a forward direction until both front wheels
are on the edge of the curb, again in a 90° position to the curb (Fig. 5.1).
Drive as slowly as possible off the curb with the drive wheels. Don't stop the chair
during descent of the curb. You will feel more secure if you can lean backwards,
but if you can't, don't worry, the wheelchair is extremely stable. As long as you
stay within its limitation, you will be quite safe.
The rear of the chair will naturally follow down the curb as you continue to drive
slowly forward.
All powered seating options need to be in home position. Your powered leg rests
may need to be adjusted to give enough clearance to climb or descend the curb.
We recommend to use the lap belt to feel more secure during descending the
curb. For extra protection we recommend to fi t every chair with leg rests.

5.9 Pushing the wheelchair
The wheelchair can be moved by pushing. In order to do so, the motors must be
disengaged using a freewheel switch. This feature was developed for the attendants
of wheelchair users and also functions as an emergency freewheel switch.
The freewheel switch has 2 positions
1.
For driving the wheelchair (Fig. 5.2).
'Drive' position: While the chair is off , turn the switch so that the lever at
the drive wheel side is pointing upwards.
2.
For disengaging the motors (Fig. 5.3 and Fig.5.4).
'Push' position: While the chair is off , turn the switch so that the lever at the
drive wheel side is pointing horizontally.
1.
The free wheel switch should only be operated by the attendant and never
by the user.
2.
A user may never be left unattended while the wheelchair is in 'push'.
3.
Never set the switch to the 'push' position on a slope! When the freewheel
switch is set to 'push', the automatic parking brake is deactivated. This makes
it possible for the wheelchair to roll down the slope.
4.
The automatic parking brake only works if the switch is set to 'drive' position.
5.
When the wheelchair is no longer being pushed, the freewheel switch should
be set to 'drive' immediately.
6.
To manually push the system you must release the motor brakes.
7.
Do not engage or disengage motor brakes unless power to the system is off .
8.
Ensure you have full control over the system when you release the motor
brakes. When you do so, the system will not have brakes.
9.
Ensure the system is on level ground before you release the motor brakes.
10.
Propel this system by the push handles only. They provide secure points for
you to hold the rear of the system to prevent a fall or tip-over.
11.
Check to ensure push handle grips will not rotate or slip off .
