seatbelt.
7. Inspect whether the gear-shift lever is at the neutral position; if not, please set the
gear-shift lever at the neutral position.
8. Inspect whether the fan switch and warm air A/C switch of A/C system are at the off
position; if not, please set them at the off position.
9. Insert the key into the electric lock and then turn it clockwise by one step so as to turn
on the power supply, and then sound the horn so as to declare that the loader is
about to start up and no other person may approach the loader.
10. Inspect the level of fuel.
11. Slightly push down the accelerator pedal, and turn the key clockwise by one more
step so as to switch on the engine starting motor. Under normal conditions, the
engine can be started up within 10 seconds, and then please release the key
immediately so as to let the electric lock return to the original position.
NOTE: An attempt to start up the engine may not last for more than 15 seconds
(the starting motor may not work continuously for more than 15 seconds), and
if the engine can’t be started up, please immediately release the starter switch,
wait at 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 can’t
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.
12. After the engine is started up, make it run at idle speed (750-800r/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.
13. When the engine is running at low speed, listen whether the engine works normally
and whether the gearbox makes any abnormal noise.
14. Inspect whether each instrument works normally and whether each lighting device,
indicating lamp, horn, wiper and brake lamp can work normally.
NOTE: special attention shall be paid to ensure that the value indicated in
engine oil pressure gauge shall not be less than 0.07MPa (idle state). If the
indicated value is less than this figure, please stop the loader and inspect
whether there is any fault with the diesel engine. With the electric lock turned
on, when the atmospheric pressure is less than 0.4MPa, the alarm buzzer (near
fuse box in the left of cab) shall sound. When the loader is started up and the
atmospheric pressure is higher than 0.4 MPa, the low pressure alarm buzzer
will stop sounding. If not, please inspect whether there is any fault with the
brake system.
15. In cold season, please preheat the hydraulic oil. Push backwards the bucket 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 boom and make
