OPERATION
03.3.7 FOLDING AND UNFOLDING THE CHAIR
Before folding the chair, you must lock the front wheels so that they are perpendicular to the direction of
movement of the chair. Fold the footrest, the tansport handles and the armrests, as indicated in paragraphs
03.3.1, 03.3.2 and 03.3.5.
To fold the chair, locate the release cable on the back of the backrest. Pull the cable and tilt the chair towards
the floor, bringing the seat close to the backrest until the release cable is tensioned again. Verify that the
system has been locked correctly by trying to open the chair without activating the cable, if it is locked the
chair will not open.
To unfold the chair, pull the release cable and separate the backrest from the seat, opening the chair, until
the cable is tensioned again. Verify that the system has been locked correctly by trying to close the chair
without activating the cable, if it is locked the chair will not close.
Once unfolded, you can unlock the front wheels again.
03.3.8 ELECTRIC TRACK
Use the electric track to facilitate the transport of the patient up stairs.
TRACK ANCHOR:
Brake the wheels of the chair to prevent the chair from moving during operation.
First install the lower part of the track, tilting it slightly and inserting the two lower horizontal bushings into
the lower hooks of the chair.
Using the bushings as turning axes, move the track towards the chair until the latchs are inserted into the
upper anchor points of the chair and the assembly is locked.
Make sure the system is securely attached by slightly pulling the track.
When you have completed the operation, unlock the wheels of the chair for normal use.
To unlock the track, you must actuate the two lower red tabs on the back of the track and pull it back.
OPENING AND CLOSING THE TRACK:
Locate the knob on the track's opening adjustment system.
Pull it to unlock the regulation system. Open the track to the desired position, depending on the conditions
of the operators and the inclination of the stairs.
Verify that the system has been locked properly by pushing it as if you wanted to close it. If it is locked, the
track will not close.
To close the track pull the knob and push the track until it stops. When it is completely closed, release the
knob. Verify that the system has been properly locked by pulling it as if you wanted to open it. If it is locked,
the track will not open.
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 the belts to perform unpredictably, which can cause injury
to the patient and/or operators.
Moisture, water, snow, ice or debris on the track belts or in the path of the stairs can cause irregular product
operation causing sudden changes in the weight that the operators must support or destabilizing the chair.
Make sure the track and track belts are clean and dry before using the set on stairs.
Before using the track, adjust the upper handle to the desired height and fold the rear levers.
