� Before the commencement of the working, use the loader to flatten the working place ,
remove crowing portions, fill depressions, and remove the ground surface which is
wet and slippery. Clear away all large and sharp stones on the working place, so as
to p revent the tires from being scratched.
� If using the loader to load materials onto or unload materials from a truck or hopper,
adjust the limit height of the caging device of the lift arm on the basis of the height of
the truck or hopper, so as to ensure that the bucket may safely enter into an
d
exit
from the truck or hopper and to avoid the impact on truck or hopper imposed
by
materials discharged from an excessively high position.

� The common shovel-loading method is suitable for the loading of bulk materials.
� Make the loader approach the materials
at
the speed under forward gear 2, align the
middle portion of the bucket with the material pile, hold the steering wheel with your
left hand, and operate the pilot joystick with your right hand so as to lower the li
ft
arm
to the position which is 500mm above the ground.
� When the loader is about one meter away from the material pile, lower the lift arm
again and make the bucket contact with the ground, and then change the forward
gear 2 to forward gear 1.

� Push down the accelerator pedal so as to insert the bucket into the material pile with
full force; when the loader cannot move forward any more, push leftwards the pilot
joystick so as to turn the bucket backwards, and then pull the control handle to the
middle position. In this way, the loader may go ahead into the material pile. Repeat
the operation mentioned above until the bucket is filled with the material.
