Second test : On ramp :
• On non slipping loading ramp (maximum slope 20 %).
• Draw a line on the slope to create a stopping reference.
• Climb on the ramp at microspeed.
• Release the joystick when the front wheels make contact with the stopping line previously drawn.
• When the machine comes to a stop, measure the distance between the middle of the front wheels and
the reference mark on the ground :
• If the distance is lower than 0,5 m(1 ft8 in) : the test validates correct operation.
• If the machine goes down again (skids, slips) of a distance higher than 0,5 m(1 ft8 in) :
