OPERATION
Operation
Work possible using wheel loader
3-87
Loading operations 0.
Select the method of operation which will give the minimum amount of turning and travel in order to provide the
most efficient method for the jobsite.
WARNING
Always keep the jobsite flat, and do not operate the steering wheel suddenly or apply the brakes sud-
denly when the lift arm is raised with a loaded bucket. This is dangerous.
Never thrust the bucket in when traveling at high speed (when loading soil or crushed rock). This is
dangerous.
When the machine is traveling or the work equipment is raised, the moment that the E.C.S.S. switch is
turned ON, the work equipment will move.
If operations are carried out with the E.C.S.S. switch left at the ON position, the moment that the travel
damper is actuated, the work equipment will move.
NOTICE
If the tires slip, the tire life will be reduced, so do not allow the tires to slip during operation.
Avoid excessive bucket shaking.
Cross drive loading 0.
Always set the wheel loader facing at a right angle to the 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 method requires the least time for loading, and is
extremely effective in reducing the cycle time.
