TROUBLESHOOTING
WHEN MACHINE RUNS OUT OF FUEL
When
starting
the
engine
again,
check
carefully
that
the
area
around
the
engine
is
safe
before
cranking
the
engine.
When starting the engine after running out of fuel, fill with fuel and bleed the air from the fuel system before starting.
For details of bleeding the air, see "REPLACE FUEL FILTER CARTRIDGE (PAGE 4-44)".
TOWING THE MACHINE
Check
that
the
wire
rope
is
of
ample
strength
for
the
weight
of
the
machine
being
towed.
Do
not
apply
a
load
to
the
wire
rope
suddenly.
If
there
is
a
failure
in
the
brake
line,
the
brakes
cannot
be
used,
so
be
extremely
careful
when
towing.
NOTICE
Towing
is
for
moving
the
machine
to
a
place
where
inspection
and
maintenance
can
be
carried
out,
and
not
for
moving
it
long
distances.
The
machine
must
not
be
towed
for
long
distances.
For
details
of
the
procedure
for
towing
a
machine
when
it
has
broken
down,
please
contact
your
Komatsu
distributor.
This machine must not be towed except in emergencies. When towing the machine, take the following precautions.
Before releasing the brakes, put blocks under the wheels to prevent the machine from moving. If the wheels are
not blocked, the machine may suddenly move.
When towing a machine, tow it at a low speed of less than 2 km/h (1.2 MPH), and for a distance of a few meters
to a place where repairs can be carried out. The machine should be towed only in emergencies. If the machine
must be moved long distances, use a transporter.
To protect the operator if the towing rope or bar should break, install a protector plate to the machine being towed.
If it is impossible to operate the steering and brakes of the machine being towed, do not let anyone ride on the
machine.
Check that the tow rope or bar is of ample strength for the weight of the machine being towed. If the machine
being towed must travel through mud or up hills, use a tow rope or bar of a strength of at least 1.5 times the weight
of the machine being towed.
Keep the angle of the tow rope as small as possible. Keep the angle between the center lines of the two machines
to within 30 degrees.
If the machine is moved suddenly, the tow rope or bar will be subjected to an excessive load, and it may break.
Start the machine gradually and travel at a constant speed.
The towing machine should normally be of the same class as the machine being towed. Check that the towing
machine has ample braking power, weight, and rimpull to allow it to control both machines on slopes or on the tow
road.
When towing a machine downhill, use a larger machine for towing to provide ample rimpull and braking power,
or connect another machine to the rear of the machine being towed. This way it is possible to prevent the machine
from losing control and turning over.
Towing may be carried out under various differing conditions, so it is impossible to determine beforehand the
requirements for towing. Towing on flat horizontal roads will require the minimum rimpull, while towing on slopes
or on uneven road surfaces will require the maximum rimpull.
