How is the hydraulic connection?
The demolition hydraulic connection to the excavator is made using rubber hoses. These tubes are connected for one end to the excavator by means of delivery and return valves, welded to the machine arm, for the other end to the hydraulic breaker. The hose connection to the breaker can be through nipples or through nipples and swivels. The delivery hole is indicated with the IN symbol. Before mounting the tool, it is important to sprinkle the upper part of the tool, that will be put into the breaker, with molybdenum disulphide grease, recommended by Hammer.
What kind of oils to use?
Only use approved oils for hydraulic mechanisms. All oils recommended by the excavator manufacturer are suitable for breaker operation. Other types of liquid for hydraulic mechanisms can only be used after authorization from Hammer.
If the greasing device does not work?
In case the greasing device does not operate for a certain period, lubricate manually.
Use of automatic greasing device
If greasing is performed by an automatic greasing device, periodically check the grease level in the container and ensure its operation.
The greasing of the tool must be carried out every two hours by means of a hand lubrication pump containing molybdenum disulphide grease.
Rules to be respected
The basic rule to be respected for a long life of the breaker, is the timely and constant maintenance.
