Tool Maintenance

Rockbreaker tool is a wear part and tool consumption is one of the key contributors to wear part costs. But with thorough and regular tool maintenance, you can reduce those costs. Download the Parts and Tools brochure for tool analysis on page 17.

When operator is carrying out the tool maintenance, ensure proper safety clothes are worn and the tool is not touched immediately after the rockbreaker has been working as it is extremely hot.  

Tool Lubrication and correct greasing practice

Rockbreaker tool is subject to extreme wear that requires proper lubrication and care to achieve a long, trouble free life. Tool lubricant must have properties to withstand high temperature and extreme pressure. We supply special tool lubricants and automatic tool lubrication systems which have been especially designed to work with Rammer products.

The greasing practice depends on application and operating method. Tool grease consumption is higher in applications where the tool is penetrating and movements are longer than in impact breaking applications where the tool is steadily against thrust ring. Greasing should be increased in dusty applications.

You can find instructions for correct greasing practices from the operator’s manual, although the operator should adjust suitable practice for the application on a daily basis. The proper procedure is reached when wet grease is visible about the length equal to tool diameter on the tool just beneath the housing bottom plate.

Tool sharpening

Genuine Rammer tools can be reconditioned by milling or turning machine and plaining. When sharpening the tool it is important that the working temperature does not exceed 200°. Never use gas cutting tools as they soften the tool and causes micro-cracks that may lead to breakages. Ask us about the same day chisel sharpening service.
