Effective and safe use of pneumatic tools requires adherence to specific operational guidelines. This section outlines the correct procedures for handling, operating, and maintaining rock drills during use, ensuring optimal performance and longevity.
Safety First:
Prior to using any tool, the operator must read and understand the operating and safety instructions provided with each tool. Always wear personal protective equipment on the job site, including safety shoes, hard hats, gloves, safety goggles, and ear protection. If there are any noise restrictions on the job site, we also recommend the use of APT mufflers designed to reduce the noise levels of our tools.
Safety goes beyond just the operator: ensure the crew, bystanders, visitors, and anybody near the tool is equipped with the correct PPE equipment and aware the tool is being used.
Tool Placement & Activation:
To start, check the work area for any obstructions that will snag the drill bit. Grip the tool handle firmly. Always have the drill bit in contact with the workpiece. Depress throttle lever to actuate, using a lower speed until a deep enough hole has been established so that the drill cannot wander. Always release the throttle lever when removing the drill bit from the workpiece.
During Operation:
Best practice is to operate the tool at full throttle, achieving the highest impact. For dust control and removing debris, the larger downward facing tools have blowout or water options, especially useful for deeper hole drilling.
Concluding Operations:
Once your task is completed, turn off the air supply using a shut-off valve or switch. To release any trapped air inside the tool and the hose, point the chisel at the work surface and operate the throttle lever with the air supply shut off. Only then should you proceed to remove the chisel tool.
Proper Handling & Storage:
Do not move tools while connected to the air supply, refer to shutdown procedure first. Seek assistance on moving tools and loading vehicles, as some models are heavy. Check tools in same method as you would prior to use. Report any issues to your supervision should you have any concerns.
Air Pressure:
The recommended air requirement for the operation of APT tools is 90 psi (6.2 bar). Lower air pressure will decrease power, too high a pressure will increase unwanted stresses in the tool. For proper CFM ratings, please refer to the specification charts shown for each tool in this catalog.
Hose Size:
APT recommends the use of at least 1⁄2” inside diameter or larger hoses to assure sufficient air flow to the tool. For portable compressor hose and longer lengths, 3⁄4 “hose is recommended. Keep the overall length of the hose to a minimum to prevent pressure loss at the tool.
Connecting Hoses:
Hoses should be rated for a minimum of 250 psi (17.2 bar). Before connecting the air hose to the tool, check the tool inlet connector to be sure it is clean and free of dirt or debris. Keeping dirt and debris from entering the tool will assure long and satisfactory operation.
Conclusion
By following these guidelines, operators can ensure the effective, safe, and efficient use of APT pneumatic tools. Prioritizing safety, proper handling, and maintenance not only protects the user and surrounding crew but also maximizes tool performance and longevity. These best practices are key to achieving reliable results and maintaining workplace safety standards.
