Efficient Working Method - Hyundai HL930A Operation & Maintenance Manual

7. EFFICIENT WORKING METHOD

1) GENERAL
(1) Lift the bucket about 40–50 cm (2 ft) above
the ground to ensure safety and to gain a
good range of view.
(2) Clear the job site and level the ground.
(3) Be careful that excessive force is not ap-
plied to the bucket.
(4) When handling hard materials, use bucket
teeth or bolt on cutting edge.
(5) When doing dumping work, put the control
lever in the DUMP position, then return it to a former state. Repeat this procedure until the
work is finished.
(6) Position the machine with its back against the wind so that dust does not get into the engine.
(7) Check if the proper bucket is used for the work.
If the capacity of the bucket exceeds that of the machine, the machine's service life may be
shortened.
2) EXCAVATION WORK
(1) Shovel work
As the machine loads on the bucket with
traveling, tires may start to slip because of
heavy load. Then lift the bucket slightly to
reduce load.
Keep the bucket shovel parallel to the
ground (if the bucket is pushed in a
non-horizontal position, power may
be reduced, and the bucket cannot
dig deeply into the heap of soil).
When the bucket is sufficiently deep
into the pile, advance the machine
with the control lever pulled down.
And by placing the control lever in the
bucket roll-back position, fill the
bucket with soil.
