Operation
Rotating the upper carriage Specific safety instructions:
After releasing the control lever, the upper carriage can rotate a little bit further
if the machine has not yet reached its operating temperature.
If the upper carriage needs to be rotated on a slope, actuate the control lever
very slowly. Proceed with extreme care and avoid abrupt movements if the
bucket is full.
If the control lever is actuated quickly, the upper carriage rotates quickly; if the control lever
is actuated slowly, the upper carriage rotates slowly.
Rotate the upper carriage to the left as follows:
☞ Push the left control lever 5 to the left A
➥ The upper carriage rotates to the left
Rotate the upper carriage to the right as follows:
☞ Push the left control lever 5 to the right B
➥ The upper carriage rotates to the right
Swivel unit brake Hydraulic swivel unit brake:
The upper carriage’s rotation is sufficiently braked by moving control lever 5 back to initial
position. Moving the control lever in the opposite direction (counteraction) brakes the
upper carriage with maximum hydraulic output.
