Instruction Manual

Caterpillar: Non-Confidential
operator can release the control lever,
which will not return to middle location. In
this course, operator should drive the
machine carefully, watching the
circumstance of the bucket being close to
the truck or the hopper, and turn back the
operation handle at any moment. the
bucket should not collide with the truck or
hopper.
When the bucket is just on the top of the
truck or the hopper, operator should step
on the brake pedal to stop the machine
and push ahead the bucket control lever to
tip the bucket forward. Put the material in
the truck or hopper, at this time operator
should watch the bucket working process
carefully, the bucket and the edge of the
truck or hopper should not make the collide.
If material is very viscous, the bucket
control lever should be operated forward
and backward several times in order to
make the collision between bucket stop
plate and lift arm time and time, and
release the material with the bucket down
and sticking into the material.
Unloading material should begin from the
front of the pile if the length of the truck is
twice or more for the width of the bucket.
Notice: When unloading, the collision
force between bucket stop plate and lift
arm should not too large, and collision
times should be low to prevent to damage
machine.
When machine finished unloading, the
operator should turn the bucket rotating
control lever back to last location until it
stops contact with lift arm, then move the
lever to the middle location. After that, the
operator moves the shifting lever to
reverse location, then release the brake
pedal to make the machine leave from the
truck or hopper. When machine leaves the
truck or hopper, the operator should drive
the machine carefully, watching the
process bucket leaving the truck or hopper,
not to collide between bucket and truck or
hopper. After the bucket pulls away from
the truck or hopper completely, the
operator can let the lift arm down when
driving, and prepare next work cycle.
Unloading at Low Location
When transporting material among fields,
sometimes unloading material is done at
low locations or locations lower than
ground level. At this time, after unloading,
bucket back should first turn to the
horizontal position, and then lift the arm.
Otherwise you cannot lift the arm because
of the interference of the work tools linkage
structure.
Carrying
When bucket is touching ground at even
level, put the gearshift control lever in
forward I gear, step on accelerator pedal to
make the machine go forward, if finding
some obstacle in process, can go on
carrying with lifting the arm a little, the lift
arm control lever should be in the position
between downside and upside when
operating the lift arm up and down, it
should not be turned to either upside or
downside position, to ensure the carrying
work.
Scraping Work
Lift the arm, and turn the bucket forward
until the cutting edge is touching ground,
the angle between cutting edge and
ground should remain about 40 degrees,
for a hard road, lift control lever, it should
be put into the floating position, and it
should be put the middle position for soft
material road, gearshift lever should be
turned backward shift, step on accelerator
pedal, to make machine backward, scrape
ground by cutting edge.
