5 OPERATORS PROCEDURE
5.1. Pre-use inspection
To ensure proper working and safe operation of the SR 1750 HE StairRobot:
• Check that there are no exposed wires in either the main lead or the pendant control
• Check that both the main plug and the continental 16 amp plug and socket are all
secure
• Check that the pendant cable is secure in the pendant and at the machine end
• Check that no cable has been deformed. If a deformation is found the use of the
machine should be postponed until the cable has been repaired
• If on the dolly; drive the robot of the dolly on a flat surface, listen for excessive or
unusual noises from any part of the machine
• Check that the ramp will raise to it’s full extend and that it’s not leaking oil. When fully
extended the ramp should cause the platform’s front edges to be in firm contact with
the floor and the tracks to be lifted of the floor at the front end about one centimetre
• Irregularities are best noticed by rising the ramp repeatedly to it’s full up position and
then quickly pressing the down button to release the pressure. If, while the ramp is
fully extended the top of the cylinder moves more than 5 mm either towards the front
or the back of the Robot then the machine should not be used
• It is quite usual for some oil to be present around the top of the cylinder, however
with the up-button pressed and the pump running there should be no oil running
down the outside of the cylinder
• Check that the down-button permits the ramp to descend, and in addition check that
the descend adjuster permits the speed of the descend to be altered. From fully
extended to fully closed should take no less than 25 seconds with an applied load of
80 Kilogram with the ascend adjuster turned maximum counter clockwise
• Check that no rubber blocks on the tracks are severely damaged or torn off
• Check the drive-tooth side of the tracks for exposed stringing cords or damage
• Check that nothing has been trapped between the tracks and the robot
• Check that when going from forward to reverse direction on the pendant button the
delay before the tracks start moving in the opposite direction is no longer than one
second. Any longer time indicates sloppiness in the drive chain which should be
investigated
• Check that the platform sits down on the lower base when lowered
•
Check that the castors of the dolly can move in all directions and are not jammed
•
Check that the cable of the winch has not been deformed
If there are no defects found the machine is ready for use. If a defect is found do not use the
machine until the Stair-Robot is repaired.
