Operation Section
When you attach work tools that require hydraulic
connections, extend the boom by approximately 1 m (3
ft) after installing the work tool onto the quick coupler.
This extra space is necessary in order to connect the
auxiliary hose.
1. Position the machine. Rest the quick coupler or the
work tool on the ground.
2. Engage the parking brake. Move the transmission
control to the NEUTRAL position and stop the
engine.
3. The hydraulic controls must be in the HOLD
position. The hydraulic controls return to the HOLD
position when the hydraulic controls are released.
4. Carefully inspect the hydraulic hoses or pipes on
the work tool for any signs of damage. The
hydraulic hoses or the pipes must be free of
following defects: Cuts, abrasions, bulging,
kinking, and dents. Do not use any work tool
unless the hydraulic hoses and the pipes are in
good condition.
5. Connect the quick disconnects on the work tool to
the quick disconnects on the machine. Ensure that
the quick disconnects are correctly engaged. The
lock rings must be fully engaged and secure.
Disconnecting a Work Tool
1. The wok tool must be resting on the ground. If
necessary, support the work tool on blocks.
2. Engage the parking brake. Move the transmission
control to the NEUTRAL position and stop the
engine. Move all the hydraulic controls to the
HOLD position.
3. Clean the quick disconnects. Pull back on the lock
rings in order to disengage the quick disconnects.
Install protective caps on the quick disconnects on
the machine and on the quick disconnects on the
work tool.
Carriages and Forks
Illustration 121 g00974120
All Caterpillar approved carriages that are used on
these machines can be installed directly to the quick
coupler.
All carriages are designed with backrests to support the
load. Wide versions should be used for additional
support when large loads are handled.
Forks
A crushing hazard exists when the boom is lowered or
from a falling load. Stay clear of the boom when the
machine is in operation. Failure to stay clear of the
boom can cause injury or death.
Failure to comply to the rated load can cause possible
personal injury or attachment damage.
Review the rated load of a particular attachment before
performing any operation. Make adjustments to the
rated load as necessary.
Personal injury or death can result from sudden
machine movement.
Sudden movement of the machine can cause injury to
persons on or near the machine.
To prevent injury or death, make sure that the area
around the machine is clear of personnel and
obstructions before operating the machine.
Refer to the topic "Load Handling and Stacking" in
Operation and Maintenance Manual, "Operation
Information".
Correct Use of Forks
• Always position the forks into the lifting pockets
before you lift a load.
• Always position the load over all of the forks so that
the weight distribution is even.
• Only lift the load if the load is within the loading
capacity that is shown on the load chart. The load
chart is attached to the dash panel of the machine.
Incorrect Use of Forks
Do not use the forks for any of the following
operations:
• Pushing the load or dragging the load
• Excavating ground embedded objects
• Attaching chains or slings
• Lifting a load with only one fork
