5.7 Obstacles & kerbs:
DANGER!
• Never descend a kerb backwards.
• 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 kerb.
• We recommend that users with upper trunk instability wear
restraint systems to keep the upright body position during
descending or ascending ramps, kerbs or obstacles.
Kerb climbing:
Always approach a kerb at 90° (Fig. 5.1).
• Approach the kerb or step, head on at a 90° angle.
• Drive forwards slowly and steadily.
• Stop the chair as soon as the castor wheels touch the kerb.
• Apply sufficient power to the motors to lift the front of
the chair up onto the kerb or step and then apply slightly
more power until the drive wheels climb the kerb or step
smoothly.
• As far as possible, keep the joystick in the straight forward
position.
The maximum obstacle or kerb climbing height is:
• Q300 M Mini: 70 mm.
The approach speed and process can vary depending on your
wheelchair drive type and castor wheel choice.
Dismounting the kerb.
DANGER!
Move the chair slowly and carefully in a forward direction until
both front wheels are on the edge of the kerb, again in a 90°
position to the kerb.
Drive as slowly as possible off the kerb with the drive wheels.
Don't stop the chair during decent of the kerb. You will feel
more secure if you can lean backwards, but if you can't, don't
worry, the wheelchair is stable. As long as you stay within its
limitation, you will be quite safe.
All powered seating options need to be in home position. Your
powered leg rests may need to be adjusted to give enough
clearance to mount or dismount the kerb.
We recommend to use the lap strap to feel more secure during
declining the kerb. For extra protection we recommend to fit
every chair with the leg rests.

5.8 Pushing the wheelchair
The wheelchair can be moved by pushing. In order to do so,
the motors must be disengaged using a freewheel lever. This
feature was developed for the attendants of wheelchair users
and also functions as an emergency freewheel lever.
The freewheel lever has 2 positions:
1. For driving the wheelchair.
'Drive' position: Turn the lever so that the lever at the drive
wheel side is positioned as shown below (Fig. 5.2 - Fig. 5.3 or
Fig. 5.6).
2. For disengaging the motors.
'Push' position: Turn the lever so that the lever at the drive
wheel side is positioned as shown below (Fig. 5.4 - Fig. 5.5 or
Fig. 5.7 - Fig. 5.8).
DANGER!
• The free wheel lever should only be operated by the
attendant and never by the user.
• A user may never be left unattended while the wheelchair is
in 'push' (Fig. 5.4 - Fig. 5.5).
• Never set the lever to the 'push' position on a slope!
When the freewheel lever is set to 'push', the automatic
parking brake is deactivated. This makes it possible for the
wheelchair to roll down the slope (Fig. 5.4 - Fig. 5.5).
• The automatic parking brake only works is the lever is set to
'drive' position.
• When the wheelchair is no longer being pushed, the
freewheel lever should be set to 'drive' immediately.
• To manually push the system you must release the motor
brakes.
• Do not engage or disengage motor brakes unless power to
the system is off.
• Make sure you have full control over the system when you
release the motor brakes. When you do so the system will
not have brakes.
• Make sure the system is on level ground before you release
the motor brakes.
• 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.
• Check to make sure push handle grips will not rotate or slip
off.
