CHECKING JOBSITE
CONDITIONS
l Examine the lay of the land and
the kind of soil at the work site to
determine the dangerous points
and the
best method of
operation.
Proceed with the work only after
making
safety
arrangements
about the dangerous points.
l Do not work when visibility is re-
duced by smoke, fog or dust. If
the jobsite is dark, install lighting
if necessary.
l Keep work site flat!
By continually grading the work
site, work efficiency will be im-
proved and machines will be able
to drive smoothly over the site. If
the work site is very sandy or
dusty, sprinkle water over the
ground before working on the
site.
l Check the load limits of bridges
before crossing.
l When operating a machine in
water or fording streams, survey
the water depth, ground condi-
tion and velocity of the water in
advance. Do not take the machine
in water exceeding the allowable
depth (up to the underside of the
axle housing).
l
The overall height of the machine
is restricted by tunnels, roof
height or overhead electric wires,
SO check first whether the jobsite
is safe. Be particularly careful
when working near power lines
as electric shock can be caused if
the machine touches the electric
cables.
BEFORE STARTING
OPERATION
CHECK BEFORE STARTING
l Carry out checks before starting
the machine. If any problem is
found, do not start the engine,
but inform the
foreman
immediately. Always keep the
machine in good condition.
l
Before operating the machine, be
sure to check the bar and pins for
setting in storage position.
The machine can not be steered
with frames locked. (In articulate
frame model)
l Always stop the engine when
adding fuel. After adding fuel,
tighten the fuel cap properly.
l Inspect the inside of the engine
room and remove any dead
leaves or papers. Dead leaves or
papers are highly inflammable
and can cause fires.
