sides of tire have not positioned yet. Inflate again after the tire is re-fixed and the edge is lubricated.

3. Regular check and tighten torques of locknuts and bolts on the front and rear wheel rims, in order to avoid
machine from rollover caused by disengagement of wheel during operation, and protect operator from
serious injury and eliminate excessive damage to the machine.

Underway of living and industrial electricity cables

1. Make sure to secure all machine parts to prevent them loosening and electric shock.

2. When driving through under living and industrial electricity cables at low speed, make sure the maximum
height falls into the range of cable safety values as required to avoid electric shock caused by hooking or
touching with cables.

3. Prevent risk of electric shock from touch with high voltage wires during transportation, operation and in
shutoff state.

Correct support for tractor

1. To descent the parts or tools onto the ground, the tractor and its parts
needed to be lifted shall be supported safely.

2. Do
continued pressure to support machine.

3. Don’t operate tractor in the case only having a jack is used for support
tractor.

Fig. 1-6 Support risk

4. Before operating jack, you should read through the user manual
carefully. Never overloading, this is the case only if rigid support deck
is stalled to avoid injury and property losses.

5. When using jack, only use it for support right under left and right axle
shaft housing of rear axle and front bracket, no need to support other
parts.

 Fill up the fuel and coolant met required grade.
 Check whether the tire pressure is normal.
 Ensure all electrical element circuits are correct and reliable.

During the engine idle running-in, please carefully check the engine, air compressor, hydraulic pump for normal

operation. If abnormal, please check if there is leakage of air, water and oil. Check the instrument for normal. In
case of abnormal, please stop immediately, troubleshoot and then run-in again.

You can start the following running-in only the engine is normally working.

With tractor at the same place, let the engine run respectively at the low, medium and high speed, whilst turn the
steering wheel to the left and the right respectively 10 times. Then observe the servo of front wheel steering to the
left and right. Inspect the sound for normal and whether steering wheel turning is easy and steady.

If any failures occur during running-in, please troubleshoot.

3.15.5 Tractor idling and running-in with load

As to the idle running-in, after the running-in of PTO and hydraulic hitch system, make sure the technical state of
tractor is completely normal and then carry out the entire tractor running-in according to table 3-2. During no-load
running-in, properly apply the single-side brake in turning
when running with a high speed.

After idle running-in, be sure the tractor technical state is normal and then carry out running-in with load. The

 Check the brake for reliable operation.
 Check the differential lock for reliable locking and unlocking.
 Check the front drive axle for reliable engagement and release.

 When faults are detected, eliminate them and then go on implementing running-in.

3.15.6 Technical maintenance after running-in

After tractor running-in, there will be some metal particles o r contaminations mixed with lubricant of the drive
system, lubrication system and hydraulic system. Therefore, it is nec

necessary technical maintenance.
Technical maintenance content is as follows after running-in:
 A fter st

steering oil reservoir. After replacing filter elements of diesel and oil filters. Fill the new lubricant as
technically required.



backward for 3min, and then drain the cleaning solution timely. Dismantle the oil absorption filter o f lifter
to clean. After reinstalling, fill the drive system and front drive axle with the new lubricant as required.

 Please service the diesel engine according to “Diesel engine use and maintenance instruction”.
 Drain the cooling water, wash the engine cooling system with clean water and add new coolant.
 Check the toe-in of front wheel, clutch, free travel of brake pedal, adjust it if necessary.
 Check and tighten all bolts, nuts and screws outside of tractor.
 For adding the grease, please refer to technical maintenance sheet.

Important:

1. In the case of tractors just leave the factory or be overhauled, they should be put into service after running-in
or their service life will be shortened.

2. Drivers should learn and master control method and usage of tractors before implementing tractor running-in.
Otherwise, there will be accidents as results of misoperation.

5 Maintenance Instruction

Technical maintenance covers a series of technical maintenance such as cleaning, checking, lubricating, fastening
each part or replacing some parts etc. Good technical maintenance could slow down the deterioration of technical
state for each part to reduce the failure and to prolong the service life, which could ensure the tractor works in good
state.

Important:

1. All maintenance should be carried out by the person specially trained and be familiar with machine features to
avoid the damage of tractor.

2. Please strictly follow the technical maintenance procedures to ensure the tractor normal work and to prolong its
service life.

3. In the warranty period of tractors, if non-professional personnel who are not familiar with the characteristics of
this machine conduct the maintenance, or in the maintenance period specified by the manufacturer no
maintenance work has been done according to the requirements, then the damage to the tractors will result in the
loss of the related right of the three guarantees of this tractor.

4.

5.3.1 If the following items occurs, please adjust it:

 Free travel of brake pedal is too large, causing brake fade.
 The free travel of brake pedal is too small, causing the semi-brake state as the clearance between the brake

pad and spinning rotor is too small.

 The left braking force is not consistence to the right braking force, causing tractor “Offset”.

Normal axial clearance between front wheel bearings 8 and 9 is

0.05~0.15mm. During the operation, if the clearance is greater
than 0.4mm, the front wheel of the tractor will mo ve from side to
side and the bearing may be damaged by the impact. Therefore, it
is necessary to adjust the clearance immediately. When adjusting,
prop up the front wheel above the ground, remove bearing cap
and pull out split pin 7 of nut 6. Screw nut 6 until the clearance
disappears, return nut 6 by 1/15~1/7 circle, then lock nut 6 with
