03.3.5 WHEELS BRAKES
The 2 rear wheels of the chair are equipped with brakes to prevent the chair from moving during the trans-
fer of the patient or during a stop.
To activate them, press down on the upper part of the pedal. To remove, press down on the front end of the
pedal.
Never leave the chair unattended with the patient, always keep it under control. Brakes should not be used
as a substitute for operator control.
03.3.7 FOLDING AND UNFOLDING THE CHAIR
Before folding the chair, it is recommended to lock the rear wheels and fold the footrest, the carrying hand-
les and the armrests, as indicated in paragraphs 03.3.1, 03.3.2, 03.3.5 and 03.3.6.
To fold the chair, locate the black release bar at the bottom of the seat. Pull the bar to the front, sliding it
through the slot, until the chair is folded down. Verify that the system has been locked correctly by trying to
open the chair without activating the bar, if it is locked the chair will not open.
To unfold the chair, pull the release bar and move the backrest away from the seat until the chair is open.
Verify that the system has locked correctly by trying to close the chair without activating the bar, if it is loc-
ked the chair will not close.
Once unfolded, you can unlock the rear wheels again.
03.3.8 ELECTRIC TRACK
Use the electric track to facilitate the transport of the patient up stairs.
OPENING THE TRACK:
To open the track, stand behind the chair, locate the side latch, open it, and pull the black tube of the track
toward you until it stops. Verify that the system has been locked correctly by pushing the track as if you
wanted to close it, if it is locked the track will not close.
CLOSING THE TRACK:
To close it, stand behind the chair. Hold the two carry handles and place one foot on the red tube of the
track. Press the tube down along the slot until it stops. The side latch will lock automatically. Verify that the
system has been locked correctly by pulling the track as if you wanted to open it, without opening the side
latch, if it is locked the track will not open.
ADJUST TRACK TIGHTNESS
Periodically check the tension of the track belts. If it is detected that the tension is not correct, it must be
adjusted through the screw at the top of each strap, with the help of an Allen key.
It is important not to over-tighten the screw as it could cause the gear bearing to make noise and may even
cause a failure of the mechanism.
INSTRUCTIONS FOR USE OF THE TRACK:
The chair can be operated on stairs by a single operator, but in extremely heavy patient loading procedures,
in rough terrain operations and, in particular situations, the use of two operators is recommended.
Never lubricate the belts. Lubrication can cause belts to perform unpredictably, which can cause injury to
the patient and/or operators.
Moisture, water, snow, ice or debris on the crawler belts or in the path of the stairs can cause uneven opera-
tion of the product causing sudden changes in the weight to be supported by the operators or destabilizing
the chair.
