Should be based on "regular maintenance" of the relevant provisions, timely check the oil level and replace the hydraulic oil.

Check hydraulic oil level

Indicating hydraulic oil level gauge on the hydraulic tank. Check the hydraulic fluid level, the machine should be parked on a flat site, put the bucket on the ground, around the frame of the straight, no angle, then the hydraulic oil level should reach the middle level meter.

Periodic replacement of hydraulic oil

Every 1000 operating hours or six months should be replaced once the hydraulic oil. As follows:

Note: In the oil change process, the machine must conduct a variety of operations, the operation should be carried out in accordance with the relevant safety procedures, attention to safety. Oil change during the course of the operation, great care should be hydraulic oil cleanliness can not allow dirt to enter the hydraulic system.

1) The bucket in the debris cleared away, the machine parked on a flat, open spaces, speed control lever in neutral position, parking (hand) brake is a brake status, bumper mounted on the frame fixed. Start the engine and run at idle for ten minutes, during which repeatedly carried out to enhance the boom, boom drop, forward tilt bucket after bucket and other activities. Finally, the boom lift to its highest position, the maximum position after dumping the bucket, the engine stalled.
2) The bucket joystick steering mechanism to push forward, turn the bucket forward under its own weight, the discharge of oil bucket cylinder; bit in the bucket to the boom lever operating mechanism to before pushing the boom to fall under its own weight, the discharge of the oil boom cylinders.
3) Clean the hydraulic oil tank below the oil drain port and tighten the oil drain plug open, discharge of hydraulic oil, and a container filled with pick. At the same time, unscrew the filler cap to speed up the process of discharge of oil.
Note: Due to the hydraulic oil at this time may be at a higher temperature, so to wear protective equipment, and careful to avoid personal injury.
4) Remove the hydraulic oil from the hydraulic tank back to the oil filter flange, remove the back to the oil filter, replace the filter. Removing the fuel filler flange bolts, remove the fuel filter cleaning.
5) Remove the fuel tank filler cap flange below the mouth wash, rinse with diesel hydraulic tank bottom and walls, and finally with a clean cloth.
6) The hydraulic tank drain plug, oil filter and flange back cover, fuel filter, tank cleaning mouth Falangaian installed.
7) with clean hydraulic fluid from the hydraulic tank filler neck, so that the oil level reaches the hydraulic oil level gauge on the scale, screw down the oil filler cap.
8) Remove the bumper frame fixed, start the engine. Operate joystick, boom lifting 2-3 times and forward, backward and side to side of the bucket to the maximum angle, so full of hydraulic oil tanks, tubing. Then run the engine at idle for 5 minutes to discharge air from the system.
9) the boom down to the bucket flat on the ground after five minutes after the engine stalled, check the hydraulic oil in the hydraulic tank level gauge whether an intermediate position, if the excess should put oil, hydraulic oil clean shortage should be added to the hydraulic intermediate position tank level gauge.
