Good maintenance can extend the service life of the long arm and enhance working efficiency, especially in tough environment.
1.Have the long arm greased at least two times every day. After working in muddy water, wash the machine before adding fuel. Check the joints of the working device to make sure it has enough fuel before starting working. Donít add new oil until completely pushing the aging oil out by operating the swing arm, rod and bucket for several times. Compact Excavator

2.Wash the machine after working in the shore to remove the salt, and add machine oil if necessary. In cold winter, the piston rod should be put back to the hydraulic cylinder to avoid the clay and water sticking to the piston rod and damage the seal ring of the hydraulic cylinder. Large Excavators

The long-arm excavator should observe the following guidelines:
1.When making a rotation, the long-arm of the excavator should be 0.5 meters high from the ground.

2.Forbid knocking the excavator vigorously when the bucket is working, walking and rotating are not allowed either.

3.The piston rod of hydraulic Excavator cylinder should not move to the bottom, safe distance should be reserved.

4.The long arm should not be overloaded.

5.Donít dig directly in the rocky area, crush the rocks before excavating.

6.The bucket load should match with the specified standards; overload will shorten the life of the long arm and the excavator.
