    Safety Precautions • Read the rock drill and power source operating manuals prior to use. • Only use the rock drill in accordance with the local working regulations on allowed working time • Check the oil flow to the rock drill. The oil flow may not exceed 30 l.p.m./max. 150 bar.
  • Page 4 • Always make sure that the rock drill labels and warning signs are legible. • Always use hoses, couplings and spares as such recommend by HYCON A/S. • Repairs may only be carried out by experienced personnel.

    A too high oil flow and/or a too high pressure results in overload of the rock drill, meaning that the lifetime of your new HYCON tool will not be as expected, and that your service and repair costs will be too high.
