1. Oil and oil filter must be replaced by factory parts according to the specified maintenance cycle. Old machines need more careful care, oil machine filter replacement time can be reduced as appropriate, in order to make the engine longer life.

2, diesel as far as possible to use regular gas stations to provide, even if the regular gas stations add diesel, do not directly join the tank, before joining the first filter (the more common way is to set socks at the refueling port).

3. Discharge water at the bottom of the diesel tank and the oil-water separator before starting work every day. Diesel filter element buy factory parts, according to the provisions of the maintenance cycle to replace the diesel filter element. To clarify, the filter paper of the factory filter element is fine, and the impurity interception is large, so it is easy to plug, and the replacement cycle of the filter element is short than that of the deputy factory filter element, so it is not a good filter element that is not blocked for a long time.

4, the air filter element is often checked, the ash of the external filter element is blown from inside to outside with compressed air, and the pressure can not be too large to prevent the filter element from blowing. Internal filtration cannot be cleaned by blowing. After cleaning the external filter for 2 or 3 times, replace it with the internal filter at the same time.

5, in order to save oil and long-term use of idle work, to prevent carbon deposition.

6, every day to check the water tank pump, to prevent water leakage phenomenon, so as not to cause the engine high temperature or cylinder.

Hydraulic walking rotation system

1. Replace hydraulic oil, oil return filter element and pilot filter element according to the specified maintenance cycle, and pay attention to whether there are iron and copper scraps absorbed on the filter element. When using the crusher, the deterioration of hydraulic oil is accelerated, and the replacement cycle should be shortened.

2, can not be short of oil for a long time. After replacing hydraulic oil or hydraulic parts, pay attention to the discharge of air. Pay attention to waterproof, do not involve deep water operations, do not use water directly when cleaning electrical parts.

3, rotary reducer, walking reducer according to the cycle to replace gear oil.

4, the pin part of the attention to clean up dirt debris, add butter. Check whether the pin bolts are loose, loose or missing every day, and tighten them in time.

5. Check the structure for cracking and deformation every day. Pay attention to the surrounding environment when parking the excavator, park on the solid and smooth hard ground, do not stop at the river, the edge of the cliff, the hillside, to prevent accidental danger.

6. When parking, the bucket cylinder is fully recovered and the bucket falls to the ground to prevent the cylinder from being hit.

Electrical system

1, pay attention to waterproof, do not involve deep water operations, do not use water to wash electrical parts directly when cleaning.

2, do not pile up debris in the battery box, especially metal tools, easy to cause a fire.

3, do not use wire copper wire instead of insurance, do not use substandard insurance replacement.

4. When the excavator is parked for a long time, the battery line should be removed to prevent the feed.

5, meter, computer board, safe box, sensor, solenoid valve and bus part to prevent rain water.

Chassis and four wheels

1. Regular maintenance and inspection of four wheels, namely driving wheels, guiding wheels, supporting wheels, supporting wheels and tracks and cleaning soil.

2, the pin part of the attention to clean up the dirt debris, add butter. When wading, water overflows the rotary gear ring, pay attention to replace the butter in the rotary gear ring.

3. Pay attention to rust prevention of cylinder rod.

4. When the excavator is parked for a long time, the exposed metal part will be coated with butter for rust prevention.

Big forearm, hydraulic cylinder, bucket part

1. Check whether the pin shaft bolts are loose, falling off or missing every day, and tighten them in time.

2. Check the structure for cracking and deformation every day. Pay attention to the surrounding environment when parking the excavator, park on the solid and smooth hard ground, do not stop at the river, the edge of the cliff, the hillside, to prevent accidental danger.

3. When parking, the bucket cylinder is fully recovered and the bucket falls to the ground to prevent the cylinder from being hit.

4, pay attention to prevent cylinder piston rod scratches and oil leakage.
