Safety Section
Engine Stopping
Direction of tr
avel – Avoid operating the machine
across the slope. When possible, operate the
machine up the slopes and operate the machine
down the slope
s. Place the heaviest end of the
machine uphill when you are working on an incline.
Mounted equi
pment – Balance of the machine
may be impeded by the following components:
equipment that is mounted on the machine, machine
configurati
on, weights, and counterweights.
Nature of surface – Ground that has been newly
filled with e
arth may collapse from the weight of the
machine.
Surface ma
terial – Rocks and moisture of the
surface material may drastically affect the machine's
traction and machine's stability. Rocky surfaces may
promote si
de slipping of the machine.
Slippage due to excessive loa ds – This may cause
downhill
tracks or downhill tires to dig into the ground,
which will increase the angle of the machine.
Width of t
racks or tires – Narrower tracks or
narrower tires further increase the digging into the
ground which causes the machine to be less stable.
Implements attached to the drawbar – This may
decrease the weight on the uphill tracks. This may
also dec
rease the weight on the uphill tires. The
decreased weight will cause the machine to be less
stable.
Height of the working load of the machine –
When the working loads are in higher positions, the
stabi
lity of the machine is reduced.
Operated equipment – Be aware of performance
featu
res of the equipment in operation and the effects
on machine stability.
Oper
ating techniques – Keep all attachments or
pulled loads low to the ground for optimum stability.
Mach
ine systems have limitations on slopes –
Slopes can affect the proper function and operation
of the various machine systems. These machine
sys
tems are needed for machine control on slopes.
Note: Safe operation on steep slopes may require
spe
cial machine maintenance. Excellent skill of
the operator and proper equipment for specific
applications are also required. Consult the Operation
an
d Maintenance Manual sections for the proper fluid
level requirements and intended machine use.

Engine Stopping
SMCS Code: 1000; 7000
Do not stop the
engine immediately after the
machine has been operated under load. This can
cause overheating and accelerated wear of engine
components.
After the machine is parked and the parking brake is
engaged, al
low the engine to run for five minutes at
LOW IDLE before shutdown. This allows hot areas of
the engine to cool gradually.

Equipm ent Lowering with
Engine Stopped
SMCS Code: 7000
Before lowering any equipment with the engine
stopped, clear the area around the equipment of
all personnel. The procedure to use will vary with
the type of equipment to be lowered. Keep in mind
most systems use a high pressure fluid or air to
raise or lower equipment. The procedure will cause
high pressure air, hydraulic, or some other media
to be released in order to lower the equipment.
Wear appropriate personal protective equipment and
follow the established procedure in the Operation
and Maintenance Manual, “Equipment Lowering with
Engine Stopped” in the Operation Section of the
manual.

Sound Information and
Vibration In formation
SMCS Code: 7000
Sound Le vel Information
The measurement for operator sound pressure
level Leq was obtained with the procedures that
are specified in “ANSI/SAE J1166 FEB2008”. The
procedure specifies the requirements of the work
cycle to use while the measurement is obtained. The
operator sound pressure level is 80 dB(A) for the cab
that is offered by Caterpillar. This reading is correct
under the following conditions: proper installation of
the cab, proper maintenance of the cab, closed cab
doors, and closed cab windows.
