3. Fill the bucket with the second load, tilt the bucket back fully,
raise the lift arm above the horizontal position, then load the
dump truck.
Let us take the load in this case as 4.9t.
The display shows the bucket load as 4.9t, and the total load
display shows 2.0.
When 15 seconds has passed since the start of the mea-
surement, the bucket load display goes out and returns to
0.0t. The total load display shows 2.0.
4. Fill the bucket with the third load, tilt the bucket back fully,
then raise the lift arm above the horizontal position.
Let us take the load in this case as 5.0t.
The display shows the bucket load as 5.0 t, and the total
load display shows - 3.0. This means that the total load is
3.0t over the target load.
The buzzer sounds and “TARGET OVER“ is displayed for 5
seconds after the target load shows -3.0. After 5 seconds,
the total load display changes to 2.0.
This is the target load after completion of loading the second
bucket. The bucket at present has a load of 5.0t, but only
2.0t of this needs to be loaded.
5. Using 2.0t as the target, load part of the present 5.0t load
into the dump truck from the bucket.
The target load of 2.0 flashes.
6. After loading, lower the bucket to the travel posture, then
raise the lift arm and measure the remaining load in the
bucket. If we take the remaining load in the bucket as 3.5t,
the target load becomes 0.5.
