OPERATIONS
LOADING SHOVEL

Do not Carry Out Operations with the Hydraulic Cylinder at the End of its Stroke.
If the cylinder is operated to the end of its stroke during opera-
tions, a large force will be brought to bear on the stopper inside
the cylinder, and this will reduce the service life of the machine,
so leave room (distance a) at the end of the stroke as far as
possible.
It is Prohibited to Use the Dropping Force of the Bucket for Operations.
Do not use the dropping force of the bucket as a pickaxe,
breaker, or pile driver. This will bring excessive force to bear on
the rear of the machine, and will not only damage the machine,
but is also dangerous.
Be Careful of Stability when Swinging.
During swing operations, the stability of the machine differs to
the front, rear, left and right, and there is danger that it may tip
over.
It is Prohibited to Use the Tilt Operation for Digging.
Do not set the teeth vertically when the bucket is pulled in, and
then use the tilt operation to carry out digging.
