3.5.11 Leveling operation
Don’t push or pull earth with bucket when the
machine travels.
1) Push dozer blade backward to fill and level
road.
2) Apply boom, arm, and bucket generally. As
the figure shows, place bucket and arm on a line
basically. Operate arm in while lifting boom
slowly. Once arm passes the vertical position,
lower boom slowly and keep the movement of
bucket plane. Operating boom, arm, and bucket at
the same time enables the leveling operation more
accurate.
3.5.12 Prevent collapse
1) Place traveling motor to the rear end of machine
to work while the machine and the digging
surface are in certain angle or perpendicular.
2) Don’t place machine at the edge of trench or
digging area.
3) Don’t dig earth under the machine.
3.5.13 Operation tips
1) In digging work, don’t let bucket collide with
crawler.
2) Try your best to place the excavator on
horizontal ground.
3) Don’t operate bucket as hammer or piling
machine. Don’t slew machine to remove blocks
or to break up wall.
