General Care
Before shutting down at the ends of each shift we recommend the following procedures:
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 liter of oil down the drill at startup of a new shift.
Flush Hammer with air/water for a few minutes. Then turn off water injection.
- 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.
