17.7.2 TESTING THE OVERLOAD LIMIT SWITCH (RK5)

The overload limit-switch RK5 will back up if the outreach limit switch RK4 for some reason would not
work.

Disable the RK4 by connecting for the test the terminals 64 and 70 in the chassis control panel with a
jumper lead.

Put a carefully weighed load (80 kg) on the platform. Place it at a distance of 100 mm from the rear edge
of the platform.

80 kg

PLATFORM LOAD

Drive the boom to a horizontal position from the chassis control panel.
Lift and lower the rear edge of the platform using the position control.

Drive the platform with the position control to a horizontal position so that that the last stage of the
adjustment procedure is lifting of the rear edge.

1.

Lowering the rear edge of the platform

2. Lifting the rear edge of the platform

100 mm
