You should release the start switch
immediately if the machine cannot start.
Wait more than 30 seconds to start again.
This is resulted from the characteristics of
the starter and the battery, if the engine
does not start after three consecutive times,
check out the reason. After removing the
trouble, wait at least three minutes to start
the engine.
13. After starting the machine, it should
remain in idle speed (750  20r/min) to
warm the machine, after the engine cooling
water temperature up to 55°C, the engine
oil temperature up to 45°C, allow the
machine work in capacity load.
14. Listen attentively whether or not the
engine works normally in the low speed,
and whether or not the gearbox brings the
abnormal sound.
15. Inspect whether or not all gauges are
normal and whether or not each lighting
attachment, indicating lamp, horn, wiper,
and brake light can work normally.
Attention: Especially pay attention to the
indicated value of the engine oil pressure,
it should not be lower than 0.1MPa (in idle
speed condition). If it is lower than this
value, you should stop and inspect
whether or not there are troubles with the
engine.
16. During winter, you should preheat the
hydraulic oil. Pull the bucket control level
back and maintain for 4 - 5 minutes, at the
same time step on the accelerator pedal.
This will cause the plate of bucket to stop
against the lift arm and cause hydraulic oil
overflow. This will make the oil
temperature rise more quickly.
17. Inspect whether the service brake, and
the parking brake systems work normally.
18. If there are no obstacles around the
machine, you should slowly rotate the
steering, observe whether there are
movements in right or left orientation.
Before Traveling
1. Operate the pilot valve control level,
pull bucket control level back to rack-back
position, and lift the lift arm to the carrying
position, namely the distance between the
bottom of bucket and ground is about
30-40cm.
2. Press the service brake pedal, and
push the parking brake lever down at the
same time to release parking brake.
Loosen the parking brake pedal slowly;
observe whether or not the loader can
move. Warning: If the machine can move,
please press the service brake pedal
immediately and press the parking brake
pedal to apply the brake. Then, inspect
whether the gearshift control system has
troubles. If the machine is on the slope,
first use wedge blocks under the wheels,
this prevents the machine from moving,
then inspect the machine.
3. Change the gearshift control lever to
forward I gear or the reverse gear, and
suitably press the throttle pedal to confirm
that the loader moves forward or backward
respectively.
4. Drive the loader to an open and flat
site, if the steering inspection has not been
carried out because of narrow site in the
previous stage. Rotate the steering wheel
now, inspect whether or not the machine
can change direction freely.
5. Check the quality of the service pedal.
In an open and flat place, drive the
machine forward in gear 1 or gear 2, first
release the accelerator pedal, then gently
press down the service brake pedal, the
machine should immediately decelerate
and stop. Attention: If the machine does
not immediately decelerate after pressing
down the service brake pedal, please pull
the parking brake lever immediately to
implement emergency brake. At the same
time, operate the pilot valve control level to
drop the lift arm to the lowest position. Turn
the bucket forward to make the bucket
