• The machine is coated with anti-rust oil when leaving the factory. It should be disassembled and cleaned before use. When reassembling the machine, apply lubricating oil to the mating surfaces and run the machine at low speed for testing.
• When connecting air and water pipes, blow out any debris inside the pipes to prevent it from entering the machine body and affecting normal operation.
• Before supplying air and water, carefully ensure that all connections are secure and reliable to avoid accidental disconnection and injury.
• Fill the oiler with oil before starting the machine. Operating without lubrication is strictly prohibited.
• When using the machine on the site containing super-high levels of gas (methane), do not use low-flash-point flammable lubricants. The machine must not be run idle, as this could cause an explosion.
• Adjust the oil valve, and add oil approximately once per hour.
• During operation, pay special attention to the risk of sudden breakage of the drill steel (drill rod). Take care to avoid being crushed between the rock drill and the air leg.
• When the machine finishes working, shut off the water supply, and then run it at low speed for a short time to drain any accumulated water inside and prevent rusting.
• The air leg, oiler and muffler cover are controlled components subject to safety certification. Users must select these parts (components) from our company to match the main unit; otherwise, we shall not be liable for any resulting issues.
• The pneumatic rock drill will generate noise, vibration and dust during operation. Operators should take precautions and wear earmuffs (noise-canceling ear protectors).
• When used in coal mines or gas-containing environments, the outer tube of the air leg is strictly prohibited from violent impact, as this could generate sparks and cause an explosion.
