1. Checking the oil level in the hydraulic tank
Note: The hydraulic oil level will change with the rising of the oil temperature in the work. Before
the operation, the oil level is in the middle of the oil gauge, while the oil level will be close to the
top of the oil gauge due to the rising temperature in the proper operation.
Warning: if the hydraulic oil or grease injects into the skin, it will cause serious
injury and damage. Please prevent your hands and body close to the hydraulic oil
leak area. You can check for leaks with cardboard or paper. If the hydraulic oil
accidentally injects into your skin, please immediately go to the hospital for
treatment.
Warning: to avoid burns, you can only do the related maintenance after the
hydraulic oil has been cooled or when the oil is cold before the daily work. When
removing the fuel filler flange cover, in order to prevent the oil spray, you need to
turn the cover slowly to release the pressure inside.
Check the oil level in the hydraulic tank every 10
hours.
1) Stop the machine on the flat ground.
2) Start the machine to make each cylinder in the
reciprocating motion.
3) Retract the stick cylinder and extend the
bucket cylinder to make the bucket fall on the
ground with the blade on the ground, and then
turn off, as shown in the picture 1.
4) Observe the hydraulic oil level through the oil
gauge on the hydraulic oil tank.
The level of the hydraulic oil can be observed
through the oil gauge (shown in the picture 2
①
) It
is required that the hydraulic oil level should be
clearly seen within the range of the oil gauge, You
cannot add too much oil that the oil level cannot be
seen through the oil gauge, which will cause
damage to the hydraulic oil lines or the oil spray. If
the oil is too full, you have to stop the engine and
discharge the excess oil through the oil drain plug
port after the oil has cooled. If the hydraulic oil lever
is low displayed in the oil gauge, or it cannot be
seen, you should promptly refuel through the oil
filler at the top of the hydraulic tank to raise the oil
level.
