Caterpillar: Non-Confidential
lever of bucket pilot valve backward (to
turn the bucket backward), then push the
bucket lever to midpoint, the machine will
continue forward to insert the material pile,
repeat the operation of inserting and
rotating the bucket until the bucket is filled
with material.
Combine Shoveling
Combine shoveling applies to shoveling
the harder or more viscous material. The
operation before the bucket is inserted in
the material is the same as general
shoveling. Move the buckets pilot valve
lever backward after the bucket is inserted
into the material, then push the lever to
midpoint to make the bucket turn upward,
therefore the bucket inserted a long way
forward. After that, the operator moves the
pilot valve lever backward, then move it to
midpoint again to make the bucket
backward rotation so that bucket could
continue forward. Repeatedly insert, bring
up the bucket, insert and rotate the bucket
until the bucket is filled with material.
Withdraw from Material Pile
Operator operates the pilot valve control
lever of the bucket after the bucket is filled
with material, rotate the bucket backward
until the block on the bucket collision with
arm, and then push the bucket control
lever to the midpoint. At this point, the
largest back tilt angle of bucket is obtained.
Raise the bucket to a certain height; make
sure the bucket avoids the material pile
when the machine reverses. While the
operator handles the steering wheel using
the right hand, pull the gearshift control
lever to the reverse position to allow the
loader to reverse. After the machine backs
away from the material pile, the operator
lowers the control arm lever to lower the
arm 30-40cm from the ground.
Material Transporting
In the following cases, material can be
transported
 The road is too soft and cannot be
done by using a truck.
 There is not a clear and level the
working site and cannot be done by using
a truck.
 Transporting by truck is not economic
al when the distance is less than 500
meters.
Keep the bottom of bucket at the
transporting location (30- 40cm from the
ground), and the bucket turning back to the
stop location (the stop plate touching the
lift arm) in the transporting process, so that
the material transporting process is smooth
and safe, and the material is not easily
scattered. Transporting speed is
determined by the transporting distance
and road condition, when machine pass a
pothole or the protuberance, the worker
should release the accelerator pedal, if
necessary may use “point braking“ by
reducing the speed, and passing the
roadblock slowly, this reduces the impact
to machine and scattering.
Warning: Lifting the bucket to a higher
location to transporting material is
forbidden. This may cause the machine to
turn over.
Unloading Material
Unload to Truck and Hopper
Release the accelerator pedal while the
wheel loader with full material is 15 meters
away from the truck or the hopper, if
necessary use the brake to decrease the
speed, and approach the truck or the
hopper slowly. At the same time the
operator operates the control lever back to
the last location, the lever will be
magnetized by the electromagnet, and the
