OPERATION
NOTICE
If the tires slip, the tire life will be reduced, so operate the machine avoiding tire slippage.
LOAD STOCK PILES
When loading the stockpile, drive the machine forward as shown below to scoop them. Reduce the load by
slightly raising the bucket if tire starts slipping due to the heavy load.
1.
Push the bucket into the stockpile as driving the machine
forward.
2.
When the bucket has dug into the stockpile deeply
enough, set the multifunction mono-lever to the boom
"RAISE" position as driving the machine forward.
Make the bucket full by setting the multifunction mono-lev-
er to the bucket "TILT" position from time to time.
Try to scoop the material in the center of the bucket so that
the load does not become uneven.
3.
When it is hard to thrust the bucket into the stockpile,
move the bucket edge upward and downward by shifting
the multifunction mono-lever to the right and left .
DIG AND LOAD ON HORIZONTAL SURFACE
• When digging the ground in digging and loading work on a level ground, set the bucket cutting edge facing
down slightly as follows and drive the machine forward. Always be careful not to load the bucket on one
side.
• The 1st in the speed range is appropriate.
Do not set the bucket cutting edge downward more than 20 °.
