Vapor Electric Door Operational Safety Check List
The Obstruction Sensing System - (must be checked on a daily basis)
The electric actuated passenger door system is designed to detect an obstruction that may interfere with door’s
operation while closing. When the Obstruction Sensing System detects an obstruction while the door is closing, the
system will stop the door and then reopen it. After a brief delay, the System again will attempt to close the door. The
System will stop and reopen the door if it detects an obstruction again. If the System detects an obstruction on its
third attempt to close the door, it will stop with the door coming to rest in the open position. Pressing the door control
command button again (ref. pg 11 & 19) will allow the operator to resume the door closing process. If a problem
persists, call the Grech Motors Service Department at 1-855-994-7324

The vehicle driver should test the Obstruction Sensing System every day before putting the vehicle into
service. To test the System, the vehicle driver should:
1. Activate the Door Command Button to move the door into its fully opened position.
2. While keeping the passenger doorway clear of objects and passengers, the vehicle driver should
create an obstruction in the doorway by placing a piece of wood or other debris in the door’s
path.
3. Next, the vehicle driver should attempt to close the passenger door by activating the Door
Command Button.
4. If the passenger door contacts the obstruction and fails to stop once it makes contact, call the
Grech Motors Service Department at 1-855-994-7324 and do not operate the vehicle.
5. If the passenger door stops and re-opens without seeming to contact an obstruction, call the
Grech Motors Service Department at 1-855-994-7324 and do not operate the vehicle.
6. If the passenger door contacts an obstruction, stops, re-opens and closes, and if it continues
repeating this process without stopping in the open position after the third cycle, call the Grech
Motors Service Department at 1-855-994-7324 and do not operate the vehicle.
7. If the passenger door fails to close when the operator puts the vehicle into gear, call the Grech
Motors Service Department at 1-855-994-7324 and do not operate the vehicle.
