JCR SUPER JET HAMMER

GENERAL CARE

Before shutting down at the end of each shift, we recommend the following procedures :

  • Flush Hammer with air/ water for a few minutes, then turn off water injection.
  • Flush Hammer with air/oil for a few minutes. This will coat the internal Hammer parts preventing corrosion / rust.
  • Never leave the tool in a wet/ muddy hole. Pull back from bottom as far as necessary to prevent the Hammer sitting under water.
  • It is also good practice to pour at least half a litre of oil down the drill at start up of a new shift.
  • If the Hammer is removed from the drill rig for any reason, it is wise to pour a quantity of oil into it and block both ends, providing the flushing as outlined in steps one and two above have been carried out. If steps one and two have not been carried out the Hammer should be stripped, cleaned and oiled before being stored.
