User manual MAKITA AN620H

[. . . ] WARNING: It is an employer's responsibility to enforce the use of safety eye protection equipment by the tool operators and by other persons in the immediate working area. Wear hearing protection to protect your ears against exhaust noise and head protection. Do not operate when under the influence of alcohol, drugs or the like. Do not point the tool toward yourself or anyone whether it contains fasteners or not. [. . . ] ⷠWhen the air hose is connected, do not carry the tool with your finger on the trigger or hand it to someone in this condition. Handle the tool carefully, as there is high pressure inside the tool that can be dangerous if a crack is caused by rough handling (dropping or striking). Stop nailing operations immediately if you notice something wrong or out of the ordinary with the tool. ⷠDo not modify tool without authorization from Makita. To maintain product SAFETY and RELIABILITY, maintenance and repairs should be performed by Makita Authorized Service Centers, always using Makita replacement parts. ⷠUse only pneumatic tool oil specified in this manual. ⷠNever connect tool to compressed air line where the maximum allowable pressure of tool cannot be exceeded by 10%. Make sure that the pressure supplied by the compressed air system does not exceed the maximum allowable pressure of the fastener driving tool. Set the air pressure initially to the lower value of the recommended allowable pressure. ⷠDo not attempt to keep the trigger or contact element depressed with tape or wire. ⷠAlways check contact element as instructed in this manual. Nails may be driven accidentally if the safety mechanism is not working correctly. Always disconnect the hose before adjusting or checking function on the tool. When changing the installation position, remove the screw with a screwdriver. Install the hook on another side for installation and then secure it with the screw. The graph shows the relation between nailing frequency, applicable pressure and compressor air output. Thus, for example, if nailing takes place at a rate of approximately 55 times per minute at a compression of 1. Pressure regulators must be used to limit air pressure to the rated pressure of the tool where air supply pressure exceeds the tool's rated pressure. Failure to do so may result in serious injury to tool operator or persons in the vicinity. Always disconnect the hose before installing or removing the nose adapter. If you like to protect the surface of workpiece, attach the nose adapter of contact element. When nailing workpieces with easily-marred surfaces, use the nose adapter. [. . . ] Choose and use nails so that the penetration amount into concrete ranges 10 mm ­ 15 mm by referring to the table below. The tool will bounce severely and a nail struck back, causing serious injuries. ⷠWhen nailing, hold the tool so that it stands upright to the driving surface. Slanted nailing may cause nails to strike back, causing serious injuries. [. . . ]
