MACHINE OPERATIONS AND CONTROLS OPERATION
CROSS DRIVE LOADING
When performing digging, set the wheel loader at a right angle
to the target stock pile. After digging in and scooping up the
load, drive the machine straight back in reverse, then bring the
dump truck in between the stock pile and the wheel loader.
This approach minimizes the time required for loading, cuts the
cycle time short and is efficient.
V-SHAPE LOADING
Park a dump truck at an angle of approximately 60 ° to the
scooping direction of the wheel loader. After scooping the soils,
back the wheel loader in such direction that it is at a right angle
to the dump truck and then move the machine forward to load
the soils onto the dump truck.
The smaller the turning angle of the wheel loader is, the more
efficient the operation becomes.
Before raising the boom to the maximum height after filling the
bucket with load, shake the bucket near the ground to stabilize
the load, then raise the bucket. This will prevent the load from
spilling to the rear.
PRECAUTIONS FOR FORKING WORK
When scooping soils up onto a pile, be careful not to let the rear counterweight come into contact with the
ground.
Do not set the bucket to DUMP position when piling-up loads.
LOW FUEL CONSUMPTION OPERATION
The fuel efficiency is better in 4th speed than in 3rd speed when performing the load-and-carry operation, cross
drive loading, V-shape loading, and the normal travel with travel speed 10 km/h or higher.
