efficiency, strong flushing and powerful torque.
Operation& Maintainence:
·Besides observance of the general safety precautions for rock
drilling operations, the following points should be attended to:
·The rifle nut and the piston are lefthand threaded Cautions should
be taken during assembling and Disassembling.
·Before operation, fill the line oiler with lubrication oil to the
required level. The drill should not work without lubrication
