To maintain stable operation and extend service life, the following maintenance practices are recommended:

• Clean the drill rods before use. Rock debris and impurities inside the rods may be blown into the hammer by compressed air, which can affect performance or damage internal components.
• Apply lubricant to the top of the hammer before each use. Installing an oil mist lubricator is strongly recommended to ensure sufficient lubrication and prevent component scoring.
• After operation, clean and inspect the hammer regularly. Use clean kerosene for internal cleaning, inspect component wear, and replace severely worn parts or failed seals in a timely manner.

Typical indicators that a DTH hammer is approaching the end of its service life include:

• A significant increase in air consumption accompanied by a noticeable drop in operating pressure
• Reduced impact energy and weak hammering action
• Severe external wear, with the wrench flats on the joints nearly worn smooth

DTH hammers are typically packed in fumigation-free plywood crates suitable for sea freight, air freight, and long-distance transportation.
