OPERATION
V-SHAPE LOADING
Position the dump truck so that the direction of approach of the
wheel loader is approx. 60 degrees from the direction of
approach to the stockpile. After loading the bucket, drive the
wheel loader in reverse, then turn it to face the dump truck and
travel forward to load the dump truck.
The smaller the turning angle of the wheel loader is, the more
efficient the operation becomes.
When loading a full bucket and raising it to the maximum
height, first shake the bucket to stabilize the load before raising
the bucket. This will prevent the load from spilling to the rear.
PRECAUTIONS WHEN PILING UP LOADS
When forming products into a pile, be careful not to let the rear counterweight come into contact with the ground.
Do not set the bucket to the DUMP position when piling-up loads.
