Effective and safe use of APT chipping hammers requires adherence to specific operational guidelines. This section outlines the correct procedures for handling, operating, and maintaining these tools 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.
Starting Procedure:
To start, grip the tool handle firmly. Always have the chisel in contact with the workpiece. Depress throttle lever to actuate, always release the throttle lever when workpiece has broken. Concentrate on correct tool positioning and guidance.
During Use:
Best practice is to operate the tool at full throttle, achieving the highest impact. A 5 to 10 second burst is preferable. Less than 5 seconds may mean the tool is overpowerful so you may consider a lighter tool to reduce operator fatigue. Greater than 10 seconds indicates the tool may be underpowered for the job, consider going to a higher weight class. Remember, the heavier the tool, the heavier the hitting power. Always release the throttle lever when repositioning the tool.
Concluding Operations:
When finished operating the tool, switch off air supply. Before disconnecting, operate throttle lever with chisel pointing to work surface to purge any residual air. Remove chisel from the tool. Do not move tools while connected to the air supply, refer to shutdown procedure first. Check tools in same method as you would prior to usage. Report any issues to your supervision should you have any concerns.
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
In conclusion, proper operation, maintenance, and safety practices are critical for maximizing the performance and lifespan of APT chipping hammers. By adhering to the outlined guidelines—ranging from safe handling procedures and optimal air pressure settings to correct tool storage and crew awareness—you can ensure a productive and secure work environment.
These steps not only protect operators and those around them but also maintain the reliability and efficiency that APT tools are known for. Always prioritize safety and care when using APT chipping hammers, and you'll achieve the best results every time.
