OPERATING THE MACHINE
3-49
The maximum digging forces are produced at
angles ß at approximately 165°.
If the machine is to develop maximum digging
forces, digging must be done slowly. The dipper cyl-
inder must have the longest possible lever arm.
To remove sand and soil adhering to the bucket, the
dipper must be stretched out to nearly horizontal
position and the bucket be brought into dumping
position. If sand and soil do not drop out of the
bucket by gravity alone, the corresponding control
lever must be moved several times forwards and
backwards. Do not move the bucket cylinder against
block, if strong shaking of the bucket is needed to
remove adhering soil.
Stop the slewing movement slowly. To stop the slew-
ing movement, release the slewing control lever
before reaching the place where work is to be done
or material to be dumped.
