66 General Maintenance
IMPORTANT: Make sure the contact between the limit switch and the target is made at the right place so that the
gripper has the time to close on its way up (gripper auto-closing mode).
12. Repeat the procedure until the limit switch is properly adjusted.
NOTE: The roller located at the front end of the limit switch must be vertically positioned. In case it is
not, you will have to unscrew all 4 screws that secure the front end to the rest of the switch, and
turn the front end either clockwise or counterclockwise in order to position the roller
vertically. Then replace all 4 screws and tighten them up.
IMPORTANT: All limit switches MUST be working at all times. Otherwise, the operator may not be aware that the
arm is not fully retracted or that the grabber is open or closed. This may cause accidents, injuries or
property damage.
