℃
are not exceeded to prevent starting engine from over-loading, during the first 30
minutes of working.

1. Engage hand brake.
2. Start the engine and let it run at medium speed.
3. Set the transmission rod on the 5

gear of “Forward” or “Reverse”,
conduct gear shifting for many times until the temperature gauge of torque converter
displays about 60 .
℃
Note:
The driver shall never leave the can and shall observe the heating
temperature during the warming up process.
b.
Warm up the hydraulic working system.
While warming up the transmission, warm up the hydraulic working system by
means of moving the hydraulic cylinder.
Note:
Do not operate the control lever to the extreme position for warning up
operation.
7.6.4 Starting grader
a) Set the gear shift at gear I or gear II on “Forward” or on “Reverse”;
b) After sounding the horn, release hand brake and step on the accelerator pedal,
the grader begins to run;
7.6.5 Instrument display during running
a. Indicator lamp:
The indicator lamp for battery charge, red;
The indicator lamp for brake service pressure, red;
The indicator lamp for hydraulic oil filter, red.
Above indicator lamps are off.
b. The following instruments must be observed:
Note:
If one of the indicator lamps mentions above lights and unusual
conditions happen in the pressure gauge of the transmission, the oil and water
temperature, the engine must be stopped immediately and check the cause of
the fault. Especially in brake pressure lamp, before starting you must check if
the line is right. When brake pressure lamp is light in running, you must stop
the grader and check brake system.
Note:
When the grader is operating on the ground, the driver must observe
the oil temperature gauge of torque converter. The oil temperature would be
ranged from 80~110 . In short
℃
-time, it allows to reach 120 , while cannot
