OPERATION
Press the "ON/OFF" button on the control panel, approach the chair to the beginning of the stairs and gently
recline it until the caterpillar drivetrain 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.
Once the flight of stairs is finished, all the elements that are not necessary for the transfer (telescopic hand-
les and caterpillar) must be folded back.
03.3.9 BASIC LOCKING SYSTEM
Use the PA-281 locking system to secure the folded chair in the ambulance.
Fold the chair as indicated in the paragraph 03.3.7. Position the chair in front of the lock with the seat at the
front. Place the lower bar that connects the two wheels in the lower groove of the lock. Using this joint as
the pivot axis, move the chair towards the lock until the upper hook engages.
Make sure the chair is properly locked by moving it back and forth.
To unlock the chair, operate the pedal of the upper hook with your foot. Tilt the chair back to release it from
the upper hook and then up to release it from the lower groove.
03.3.10 CHAIR + TRACK LOCKING SYSTEM
Use the PA-271 locking system to fix the folded chair in the ambulance together with the electric track.
Fold the chair and track as indicated in paragraphs 03.3.7 and 03.3.8.
Position the chair in front of the lock with the seat at the front. Place the wheels of the chair in the lower
positioners of the lock. Using this joint as the pivot axis, move the chair towards the lock until the upper
hook engages.
Make sure the chair is properly locked by moving it back and forth.
To unpin the chair, open the hook by pulling the upper handle. Tilt the chair back to release it from the
upper hook and then up to release it from the lower positioners.
