Hydraulic breaker mounted on excavator is an effective device to break rock, break concrete and hard materials. In order to breaker is always in good operating condition, selection(suit excavators), maintenance and technical operation are very important.

1. The size of hydraulic breaker and excavator
   There are many types of excavators can be mounted hydraulic breaker and each has many different sizes, it is necessary to ensure the appropriate size of breaker and excavator. Therefore, the first thing to check capacity and scalability of excavator to ensure that breaker can be fitted .

The second point is the pressure and flow of hydraulic lines for breaker. Most hydraulic lines are taken from excavator, this parameter must also be consistent with breaker. Two parameters are the basis to determine the most suitable type of breaker for an excavator or identify excavator for a kind of breaker which investors require.

2. Maintenance of hydraulic breaker
   Head of breaker (top) and bushing are two most important parts of breaker. It is necessary to maintain regularly with suitable lubricants, normally after 7-8 hours. However, condition of work will determine the degree of lubrication. If the breaker are put in dusty conditions and horizontal position, must be lubricated more often.

Like most other construction equipments, hydraulic breaker should be checked daily, weekly and annual. Before working, the operator must check the plugs, rings, bolts. If these parts are loose or damaged, they must be replaced before operating. When working with abrasive and sharp materials, it is necessary to examine more the soft tube (hydraulic tube) daily.

Check for cracks, abrasion on the surface weekly. Check the connection position between excavator and breaker every month.

3. Maintenance of excavator

Failure of excavators can also lead to failure of breaker. The most important part is  hydraulic system because the breaker uses hydraulic lines from the excavator. This is the reason why manufacturers of hydraulic breaker always require to check regularly and maintain hydraulic system of excavators.

In addition, the excavator must be checked and maintained as required by the manufacturer.

4. Operation of hydraulic breaker

Like any hydraulic equipment, during operating time hydraulic lubricants must be warm enough not to damage rubber gasket quickly by the viscosity of lubricants.

Ensure breaker big enough for required job. When the working time is limited, stone is hard and thick, bigger breaker will bring greater efficiency.

5. Store of the hydraulic breaker

Store of breaker is as important as maintenance. The breaker is not properly stored , can cause internal damages. Store of breaker must comply with the requirements of manufacturers because most of breakers should be stored in vertical position but some kinds are still required to place horizontally.

When storing breaker, all parts must be lubricated and the inner space is filled with lubricants to prevent to be oxidized and contaminated.
