least 30 seconds and then attempts to start up the engine again. This is jointly
required by the features of starting motor and battery. If the loader cannot be
started up in three attempts, please carry out inspection, eliminate the fault, wait at
least three minutes, and then attempt to start up the engine again.
13. After the engine is started up, make it run at idle speed (700~800r/min) so as to warm
it up. Only after the temperature of the diesel engine cooling water reaches 55
℃
and
the temperature of engine oil reaches 45
℃
may the fully-loaded operation be carried
out.
14. When the engine is running at low speed, listen whether the engine works normally
and whether the gearbox makes any abnormal noise.
15. Inspect whether each instrument works normally and whether each lighting device,
indicating lamp, horn, wiper and brake lamp can work normally.
NOTE: Pay special attention to the engine oil pressure. The value indicated may not
be less than 0.07MPa (idle state). If the indicated value is less than this figure,
please stop the loader, inspect whether there is any fault with the diesel engine.
After the electric lock is turned on, the low brake pressure warning lamp will flash,
and the warning buzzer will sound; about half a minute after the engine is started
up, the low service brake pressure warning lamp shall go out. The warning buzzer
shall stop. If not, please inspect whether there is any fault with the brake system.
16. In cold season, please preheat the hydraulic oil. Push backwards the pilot joystick and
hold it there for 4-5 minutes, and at the same time push down the accelerator pedal,
so as to make the stopper of the bucket is pressed against the lift arm and make the
hydraulic oil overflow. In this way, the temperature of hydraulic oil will increase rapidly.
17. If there is no obstacle around the loader, please turn the steering wheel slowly, and
observe whether the loader turns.
4.3.3 TRAVELLING OF LOADER
1. Operate the pilot control valve handle so as to
move the bucket backwards to the limit state;
raise the lift arm to the transportation position,
namely the position whereby the lower
articulated point of the lift arm is 500-600mm
above the ground.
