Safety Section
Before Operation
Clear all personnel from the machine and from the area.
Clear all obstacles from the path of the machine.
Beware of hazards such as wires, ditches, etc.
Make sure that all windows are clean. Secure the doors
in the open position or in the shut position. Secure the
windows in the open position or in the shut position.
Make sure that all mirrors (if equipped) are clean. For
the best vision of the area which is close to the
machine, adjust the mirrors. All mirrors should be
adjusted for optimal visibility while the operator is
seated in the cab.
Make sure that the machine horn, the backup alarm (if
equipped), and all other warning devices are working
properly.
Fasten the seat belt securely.
Make sure that the load charts and the instruction
plates are in place and that the load charts and the
instructions can be read.
Operation
Machine Operating Temperature
Range
The standard machine configuration is intended for
use within an ambient temperature range of -40 °C (-
40 °F) to 50 °C (122 °F). Special configurations for
different ambient temperatures may be available.
Consult your Caterpillar dealer for additional
information on special configurations of your machine.
Machine Operation
Check for proper operation of the steering controls and
of the braking controls for the machine while the
machine is moving slowly in an open area. Check the
steering controls and the braking controls while the
boom is retracted fully and the work tool is just clear of
the ground. With the machine in a stationary position,
check for the proper operation of the other controls for
the machine. Unless the machine frame is level, do not
raise the boom. The boom should only be extended if
the machine frame is level. Extend the boom and retract
the boom several times in order to warm the hydraulic
oil.
Travel
Only operate the machine while you are in a seat. The
seat belt must be fastened while you operate the
machine. Only operate the controls while the engine is
running.
When you travel on the roadways, operate the
machine in two-wheel steer mode only.
Before you maneuver the machine, make sure that no
personnel are between the machine and the work tools.
Use caution when you change direction of travel. Use
caution when you operate the boom. Use caution when
you are picking up loads or when you are setting down
loads. Travel in the direction of the best visibility. Travel
with the boom fully retracted. Also, travel with the boom
lowered as far as possible. Maintain adequate ground
clearance for conditions. Never travel if a load is raised
beyond the travel position. Be careful to avoid any
ground condition which could cause the machine to tip.
Avoid any conditions that can lead to tipping of the
machine. The machine can tip when you work on the
following obstacles: banks, hills, and slopes. If the
machine is equipped with stabilizers the stabilizers must
be fully raised before you move the machine.
Lifting Capacities
Maintain control of the machine. Do not overload the
machine beyond the machine capacity. Ensure that the
correct load chart is referenced. Loads must be within
the weight limit of the machine and loads must be within
the load center limit for the machine. Lifting capacity
decreases as the load is moved further from the
machine.
Note: If an 180-6137 Coupler Adapter Gp for a work
tool is installed on the quick coupler, reduce the load
carrying capacity of the machine by 200 kg (440 lb) for
all work tools and with the boom in any position. Refer
to Operation and Maintenance Manual, "Lifting
Capacities" for additional information.
Ensure that the tires are serviceable and that the tires
are inflated to the correct pressure.
On machines that are equipped with a frame leveling
switch, always level the frame before you raise the
boom or before you lower the stabilizers. Never
operate the frame leveling switch when the boom is
raised or when the stabilizers are lowered. Check that
the frame is level after you lower the stabilizers. If
necessary, adjust the level of the frame. Use the
stabilizers in order to make the adjustment. Do not
adjust the position of the stabilizers when the boom is
raised. If the frame is not level, do not raise the boom.
Before you transport a load or before you elevate a
load, the load must be adequately secured on the forks
or on the work tool. Any loads such as pipe,
scaffolding, lumber and beams must be adequately
secured.
Use lifting slings that are approved and use lifting
slings that are load tested. Also, all wire ropes or
chains must be properly maintained. The wire ropes
and chains must meet local regulations. You must know
the load carrying capacity of these devices and you
must know the correct use of these devices.
