Lubrication
During hammer operation, continuous and adequate lubrication must be supplied. Otherwise, the hammer parts will be worn out quickly. Rock drill oil must be used since it has the emulsifying and viscosity additives to deal with high pressure and high air flow and water presence. Oil should be injected into the air stream.
The oil also acts as a seal on the surface of running parts to help use air efficiently. Check the lubrication oil tank at least twice per day to make sure enough lubrication is supplied to the DTH hammer.
