1. Working Angle
It is very important to keep the correct working angle of 90° to the workingsurface. If not, the tool life will be shorted, and take bad results on theequipment, such as high contact pressure between tool and bushings, wearaway the surfaces, broken the tools.
2. Lubrication
Lubrication of the tool/bushing regularly is necessary, and please use
correct quality high temperature/high pressure grease. This greases carprotect the tools on the extreme contact pressures generated by an incorrectworking angle, leverage and excessive bending etc
3. Blank Firing
When the tool is not or only partially in contact with the work surface, use thehammer will cause heavy wear and damage to the parts. Because the toolbeing fired down on to the retainer pin, will destroy the upper retainer flatadius area and the retaining pin itselfTools should be examined regularly, such as Every 30-50 hours, and groundout the damage area. Also check the tool in this opportunity and see if thetool bushings for wear and damage or not, then replacement orreconditioning as necessary.
4. Overheating
Avoid to strike in same spot more than 10 - 15 seconds. Too much timehitting may lead to excessive heat build-up at the working. and may causethe damage as "mushrooming"shape.
5. Reconditioning
Normally, the chisel no need reconditioning, but if lost the shape on theworking end can cause high stresses throughout the tool and hammer.Reconditioning by milling or turning is recommended. Welding or flamecutting is not recommended
