3 Are you over 18 years old…? Do you suffer from Color Blindness…?
4 Cartridge Operated Tools To use cartridge operated tools you: –Must be 18 years old –Can NOT be color blind –Must be approved by your supervisor or instructor –Comply with all laws, rules, and regulations Always use the strictest caution! –Several deaths and injuries occur each year from unsafe use of cartridge operated tools Always be serious! –These are high risk tools, not toys!
5 This lesson will include: 1)The Tool & the Tool box… 2)Applications / Base Materials... 3)Cartridges… 4)Fixings 5)Safe use & Safety Features.. 6)Practical Use & Misfires...
7 Operating Principles.. There are two main types: Indirect-Acting A device that uses explosive powder to propel a captive piston against a fastener to drive the fastener into a structural element. In some areas, the generic term powder actuated tool is used. Direct-Acting With this type of tool, the explosive force of the cartridge acts directly on the fixing (fastener), driving it along the barrel, into the wall or material.
8 In the Tool Box.. The Box. The Tool (Not a gun!) Spare Piston. Spare Buffer. Goggles. Hearing Protection Devices (HPD). Cleaning Kit. Oil.
9 Tool strip & Maintenance 8mm Barrel. Body. Inspect Piston:- Bent, Chipped hammer. Inspect Buffer:- Never Oil. Trigger Section:- If fails, return to supplier. Clean Carbon.
10 Nose Section:- 5,000 Fires. Body Section:- 10,000 Fires. Always inspect tool on taking charge from supplier/vender, and BEFORE each use. Assemble tool and test fire (unloaded test fire) to hear firing mechanism.
17 Cartridges Red (MH) cartridges will carry out 95% of all tasks. Remember: Always conduct a test fire
18 Cartridge Safety Cartridges should be stored in a strong metal/plastic box. Box should be locked at all times. accessed by Authorized Persons Only (APO). Record all issues and/or use. Cartridges must not be sent in the mail. Cartridges must not be taken on public transport. Drivers must carry a Material Safety Data Sheet and mandated shipping papers. Do not throw cartridges on fires. Any unused or misfired cartridges should be collected and returned to supplier.
21 Safe Use & Safety Features Common Safety Features: Drop Protection Device Cartridge Noise Reduction vents. Contact Pressure. Protected power regulator. Cushioned hand grip.
22 Safety checklist Things to do. Always refer to the manufacturers instruction manual. Inform all persons in the area. Ensure that users have been trained Ensure tool is in good repair. Inspect local environment and surroundings. Ensure tool is at right angles to fixing surface.
23 Ensure you use the correct fixing, piston, cartridge combination. Immediately change/replace a damaged piston. Always wear the correct eye-protection and hearing protection. Ensure the tool is inspected, cleaned and lubricated after use. Keep cartridges not being used in the tool box or container. Always conduct a test fire.
24 Things NOT to do Do not use a suspect tool Do not use force when loading cartridges. Do not load a cartridge before you need it. Do not leave a loaded tool lying about. Do not point a tool at persons. Do not fix where another fixing has failed.
25 Do not strip a tool down when it is loaded. Do not press tool against your hand. Do not leave cartridges about job site. Do not insert cartridges before the nail or stud is loaded. Do not joke, fool about, or wave tool in the air. Horseplay and/or irresponsible use will result in disciplinary action and/or loss of privileges.
27 Practical use & Misfires Select power setting. Load fixing. Load cartridge. Find a comfortable position. Aim on required surface. Take up contact pressure. Ensure tool is at right angles to target. Fire when ready. Inspect test fire and then adjust to suit.
28 Misfires If Cartridge does not fire:- Release contact pressure without removing nose from surface of target. Hold and count to 30 slowly. Re-apply pressure and fire, if it fails repeat procedure. If Cartridge still will not fire, advance cartridge strip one place and continue.
