Teaching the User
The user is taught how to use this device by trained staff who will reference these Instructions for Use.
Adjustment Options / Features
Folding
Bring the backrest to the maximum horizontal position, loosen the knee angles and swivel the footrest over and down
onto the seat unit (Fig. 9). Move the seat tilt adjustment to a horizontal position and lower the seat unit down to the
ground (see seat height adjustment).
Caution: Hold the frame with one hand when folding to avoid it tipping over. Be careful not to catch your fingers.
Adjustment of the seat height
The seat unit can be lowered down to the ground. (Fig. 10)
Apply the right foot pedal at the back of the base frame. (Fig. 4) Now push the seat unit down (at the back, the armrests
or the push bar, if available) or pull it upwards until the desired height is reached. To keep the height, simply remove
your foot from the pedal. The seat height can also be adjusted during use of the chair. It may then be necessary for two
people to lift the seat to the desired height. For safety reasons the seat height adjustment can be locked. The adjustment
is locked when the locking pin to the left of the pedal is engaged (Fig. 6). To unlock, pull out the locking pin and do a
quarter turn.
Important: The seat height adjustment should always be locked during use of the chair.
Caution: When adjusting the seat height one person must secure the seating systems with both hands to avoid sudden
changes of the child’s position. We recommend carrying out this setting without the child in the seat unit.
Adjustment of the seat tilt-in-space
To adjust the seat tilt-in-space, use the pedal on the left side of the rear frame (Fig. 5 + 11).
First, engage the brakes. (Fig. 12) Now either push the seat unit forwards (at the back, the armrests or the push bar, if
available) or pull it backwards until the desired angle is reached. To keep the angle, remove your foot from the pedal.
The seat tilt-in-space can also be adjusted during use of the chair. It may then be necessary for two people to adjust the
desired seat angle. For safety reasons the seat tilt-in-space adjustment can be locked. The adjustment is locked when the
locking pin to the left of the pedal is engaged (Fig. 5). To unlock, pull out the locking pin and do a quarter turn.
Important: The seat tilt-in-space adjustment should always be locked during use of the chair.
Caution: When adjusting the seat tilt-in-space one person must secure the seating systems with both hands to avoid sud-
den changes of the child’s position. We recommend carrying out this setting without the child in the seat unit.
Parking brake function
Locking / releasing the castors
The rear castors are equipped with easily accessible and easy to use brakes. To lock the castors press the locking device
down. (Fig. 12) By pushing the locking device up again the castors become flexible. (Fig. 13) The brakes prevent the cas-
tors both from turning and from swivelling, so that the base frame can be safely parked via the rear wheels alone.
