CORDLESS NAILER SAFETY WARNINGS

1. Always assume that the tool contains fasteners. Careless handling of the nailer can result in unexpected firing of fasteners and personal injury.
2. Do not point the tool towards yourself or anyone nearby. Unexpected triggering will discharge the fastener causing an injury.
3. Do not actuate the tool unless the tool is placed firmly against the workpiece. If the tool is not in contact with the workpiece, the fastener may be deflected away from your target.
4. Disconnect the tool from the power source when the fastener jams in the tool. While removing a jammed fastener, the nailer may be accidentally activated if it is plugged in.
5. Use caution while removing a jammed fastener. The mechanism may be under compression and the fastener may be forcefully discharged while attempting to free a jammed condition.
6. Do not use this nailer for fastening electrical cables. It is not designed for electric cable installation and may damage the insulation of electric cables thereby causing electric shock or fire hazards.
7. Always wear safety goggles or safety glasses with side shield, and a full face shield when needed.
8. Keep hands and feet away from the ejection port area.
9. Follow instruction for lubricating and changing accessories.
10. Always remove the battery cartridge before loading the fasteners, adjustment, inspection, maintenance or after operation is over.
11. Make sure no one is nearby before operation. Never attempt to drive fasteners from both the inside and outside of wall at the same time. Fasteners may rip through and/or fly off, presenting a grave danger.
12. Watch your footing and maintain your balance with the tool. Make sure there is no one below when working in high locations.
13. Never use fastener driving tools marked with the symbol "Do not use on scaffoldings, ladders" for specific application for example:
    • when changing one driving location to another involves the use of scaffoldings, stairs, ladders, or ladder alike constructions, e.g. roof laths;
    • closing boxes or crates;
    • fitting transportation safety systems e.g. on vehicles and wagons.
14. Check walls, ceilings, floors, roofing and the like carefully to avoid possible electrical shock, gas leakage, explosions, etc. caused by stapling into live wires, conduits or gas pipes.
15. Use only fasteners specified in this manual. The use of any other fasteners may cause malfunction of the tool.
16. Do not tamper with the tool or attempt to use it for other than driving fasteners.
17. Do not operate the tool without fasteners. It shortens the service life of the tool.
18. Stop driving operations immediately if you notice something wrong or out of the ordinary with the tool.
19. Never drive fastener into any materials which may allow the fastener to puncture and fly through as a projectile.
20. Never actuate the switch trigger and safety lever at the same time until you are prepared to fastener workpieces. Allow the workpiece to depress the safety lever. Never defeat its purpose by securing the safety lever back or by depressing it by hand.
21. Never tamper with the safety lever. Check the safety lever frequently for proper operations.
22. Always remove fasteners from the tool when not in use.
