REMARK
It may not be possible to measure the weight of the load when carrying out the following operations.
When the boom is not kept raised continuously for at least 1.5 sec.
When the boom is operated to RAISE continuously but the lifting speed is not constant
When the boom angle when starting the RAISE operation is near horizontal
If the result of the measurement is not displayed on the load meter, start the scooping operation with the bucket at
a low position (close to the ground surface), raise the boom at a constant speed, and keep the boom raised contin-
uously for at least 1.5 sec.
SUBTRACTION FUNCTION
The following explanation assumes that after setting the remain
mode, the target load is 12 tons as shown in the diagram on
the right and that B is selected as the type of material.
1. This is the first load.
The result of measuring the load in the bucket is 5.1 tons.
12.0 - 5.1 = 6.9, so the next target load is displayed as 6.9
tons.
2. When 15 seconds pass after measuring, the bucket load is
deleted and the load is displayed as 0.0 tons.
