Frequently Asked Questions (FAQ)

Q: What size air compressor do I need for the RB777?

A: The RB777 requires an air compressor that can deliver at least 34 L/s (72 cfm) at a pressure of 6 bar (87 psi). We recommend using a compressor with a slightly higher capacity to ensure optimal performance.

Q: What is the difference between a rock drill (like Y26) and a pneumatic breaker (like RB777)?

A: The main difference is function. A rock drill (Y26) rotates while hammering to create a hole. A pneumatic breaker (RB777) only provides a powerful hammering action to break and demolish materials, without rotation.

Q: What kind of maintenance does the RB777 require?

A: Daily maintenance includes checking all bolts for tightness and ensuring proper lubrication through the air line. Regular inspection of wear parts like the piston and tool retainer is also recommended. Refer to the manual for a full maintenance schedule.
