[. . . ] ⷠ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. Do not activate the tool unless the tool is placed firmly against the workpiece. [. . . ] Be sure that dust, sand, chips and foreign matter will not enter the tool in the place where you leave it setting. ⷠDo not point the ejection port at anyone in the vicinity. ⷠ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. 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 60 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. Attach the board adapter for plaster board and other siding boards, and the floor adapter for flooring. The board adapter is attached to the contact element cover when shipped. When unable to remove the nose adapter easily, use a slotted bit screwdriver and the like. [. . . ] Do not place the contact element against the workpiece with excessive force. Pull the trigger fully and hold it on for 1 ­ 2 seconds after nailing. After using the change lever to change the nailing method, always make sure that the change lever is properly set to the position for the desired nailing method. If moisture is allowed to enter the tool, it may result in poor performance and possible tool failure. [. . . ]
