occur
Air condition-
ing system
1
The air volume switch, temperature setting switch, defrost setting switch, air mode switch, auto
mode switch on the A/C panel functions normally and is indicated correspondingly on the LCD;
the temperature, air volume, direction at the air outlet is the same with setting value on the

and air volume icon on the display disappears; press the up/down regulation button " " and " " on
the temperature setting switch "TEMP" simultaneously for more than 3 seconds. If "E-" appears

Driving test
1
Starting the complete machine: it starts normally, and listen to the engine and air filter, no abnor-
mal sound is heard, and it turns off normally without delay; observe the engine under the diesel
engine idling and top speed, and it shall not stall
2
Starting the complete machine: adjust the complete machine operating idle speed to a level
more than 950rpm and the engine does not stall with the bucket lifted
3
Starting the complete machine: visual check that no trouble code appears on the LCD of instru-
ment panel, and no indicating identification, alarm and flashing appears on the instrument panel
or normally on.

Pilot shutoff function: the pilot shutoff lever is at OFF position, operate the pilot lever and the
work implement shall not act; the pilot shutoff lever is not installed reversely and has no interfer-
ence with housing;
7
Detection of bucket automatic reset: the bucket is unloaded, lift the boom to the highest position
to make the bucket under discharging state and then take back the bucket and it should stop
moving automatically and then control lever returns back to neutral position when the bucket
comes near to the switch and bucket limitation magnet. Then lower the boom to place the
bucket on the ground, at this time, check the bucket and it should be horizontal to the ground;
and the engine is at full throttle during this process
8
Detection of boom automatic reset: boom limitation: lift the boom and it should stop rising when
it reaches the setting highest position; the control lever returns back to neutral position automat-
ically. The engine is at full throttle during this process
9
Work implement limitation: visual check that the bucket limit block contacts with boom and
rocker arm limit block when the boom is lifted to the highest position for discharging; take back
the bucket when the boom descends to a position that its front pin is about 500mm(19.7In) away
from ground, visual check that boom limit block contacts after taking back the bucket and the
clearance between boom and bucket is more than 5mm(0.197In)
10
Inspection of work implement running: lift the boom during which no abnormal sound shall
occur; no twisting to the bucket during taking and holding back the bucket when the boom is
lifted to the highest position and lowest position;
11
Floating function and inner leakage detection: when jacking up the bucket backward, visual
