.
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 operation of the product causing sudden changes in the weight to be supported by
the operators 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.
Press the power button on the control panel, approach the chair to the start of the stairs and
gently recline it until the tracked powertrain is on top of the first few steps.
The second operator must extend the front telescopic handles and hold them throughout the
operation.
Press the UP button if you want to go up the stairs, or the DOWN button if you want to go
down.
