Hammer care vital

Greasing is important and although larger models tend to be self-lubricating using cartridge systems, this still requires that the operator replace the cartridge when it is empty.“The tool should be removed at least once a month,” Vinella said, “so that the condition of the bushes can be determined. An operator should get to know his hammer, and the best way is to remove the tool and inspect the internals regularly.”Using the right tool for the conditions is important, and Sandvik has special chisels for hard rock. These provide durability and performance in hard rock, but if used in soft rock they can jam and be damaged when being recovered. Vinella says most operators try to make do with one tool, but one of his customers religiously calls Walkers Hammers to change tools whenever a hammer moves to different rock conditions.
