c. Check the engine filter;
Check the indicator for intaking-resistance in the air filter is in normal
condition or not
；
d. Check the oil level indicator of the hydraulic oil tank;
Carry out this check after lowering the blade, hydraulic cylinder on the ground
and cooling hydraulic oil (See 8.3.6.c);
e. Check the following with the engine running:
- Steering, when running the steering wheel to the left and to the right. The
steering must run easily and the front wheel steering must react;
- Brake system, the control lamp of service pressure must not light.
After traveling a short distance, check the function of the brake system by
stepping down brake pedal.
7.6.2 Starting engine
a. Release the hand brake and gear shift lever to idle (If fail to do this, the engine
will not start);
b. Insert the key into the ignition switch to turn I gear;
Note: All lamps light and the instrument indicate, this shows all electrical lines
are right. Otherwise, they will be checked.
c.
Step down the accelerator pedal (Approximately 1/4 of engine speed);
d.
Turn the starter knob (Second step). Release the starter knob as soon as the
engine runs. Do not keep the starter running continuously for more than 15
seconds;
Note:
In order to protect the battery, the time interval of 1~2min shall be
remained for each starting.
e.
As soon as the engine runs smoothly, the engine speed shall be reduced. At
the same time, the gauge is light and the indicator is off;
Note:
Pay attention to avoid running at high speed when the engine is at low
temperate; the engine oil temperature will rise after short-time traveling on
road.
f.
The choice of the lubricating oil depends on the temperature at which the
engine is started. You could not take the effect of environment temperature
into consideration if use stipulated oil in winter (See 8.2.4);
g.
Pay attention to the good condition of battery. Lowering the limit temperature
by 4
～
5 is possible by raising the battery temperature to about +20 . This
℃
℃
is done by removing the battery with the engine stopped and storing it in a
warm room. When installing the battery, keep contact surface of the terminal
clean and bright and endure good contact.
7.6.3 Temperature rise in transmission and hydraulic system
If the grader has been idle for long-time, especially at temperature about or
below 0 , the transmission and hydraulic system must be warmed up at medium
℃
