OPERATION
AFTER STARTING THE ENGINE
17VX3
Keep engine speed low until the engine oil
pressure warning lamp goes out. If does not go
out within
10
seconds, stop the engine and
investigate the cause before starting the engine.
Failure to do so, can cause engine damage.
With any piece
of
hydraulically operated equipment,
it
is
EXTREMELY IMPORTANT that the hydraulic
fluid be thoroughly warmed fluid-up
BEFORE any
work
is
begun. A warm-up period
is
time well spent
in
preventive maintenance.
Practice the following warm-up procedure before
attempting full load operations.
1.
Allow the engine to warm up at LOW IDLE for
at least five minutes.
Engage and disengage attachment control
levers to help speed warm-up of hydraulic
components.
2.
To warm
up
the hydraulic oil, move the engine
throttle lever to medium engine speed.
Run
the
engine for about five minutes while
intermittently holding the bucket control lever
in
the bucket dump position.
Operate the bucket control lever for
10
to
15
seconds and then return the control lever HOLD
position to ten seconds.
3.
Move the engine throttle lever to maximum
engine speed. Run the engine for an additional
five minutes while intermittently holding the
bucket dump position.
This will allow the oil to reach relief pressure,
which causes it to warm more rapidly.
Cycle all controls to allow warm oil to circulate
through all cylinders and lines.
4.
Observe the OK warning monitor frequently
during the operation.
Be sure to perform the pro-operation warm-up
procedure whenever the hydraulic oil temperature
is
lower than 20°C at start-up.
"BREAK-IN" OPERATION
In
case
of
the new machine, as the severe operation
from the beginning will have a bad influence upon
the machine life, perform the enough break-in
operation as described the right table.
