[. . . ] 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. 1) 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. general Tool Handling Guidelines: (1) Always assume that the tool contains fasteners. [. . . ] 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 stapling operations immediately if you notice something wrong or out of the ordinary with the tool. ask Makita's Authorized service centers for periodical inspection of the tool. To maintain product SAFETY and RELIABILITY, maintenance and repairs should be performed by Makita Authorized Service Centers, always using Makita replacement parts. 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 contact element depressed with tape or wire. Staples may be driven accidentally if the safety mechanism is not working correctly. For proper lubrication, the tool must be fired a couple of times after pneumatic tool oil is introduced. Always disconnect the hose before adjusting or checking function on the tool. The tool works only when the contact element is placed against the workpiece and the trigger is pulled with the contact element being depressed. Before use, make sure that the contact element work in order by checking according to the following procedure. And then release the trigger and place the contact element against the workpiece. If the tool works in the above procedure, the contact element does not work in order. 8 & 9) If a staple is driven too deep, turn the adjuster clockwise. If a staple is driven too shallow, turn the adjuster counterclockwise. When changing the installation position, remove the screw with a screwdriver. Install the hook in desired position and then secure it with the screw. select a compressor that has ample pressure and air output to assure cost-efficient operation. The graph shows the relation between stapling frequency, applicable pressure and compressor air output. [. . . ] To drive a staple, you may place the contact element against the workpiece and pull the trigger, or (Fig. Pull the trigger first and then place the contact element against the workpiece. (1) method is for intermittent stapling, when you wish to drive a staple carefully and very accurately. However when the tool is set to the "Intermittent stapling" mode, WITH THE TRIGGER HELD IN A HALF-PULLED POSITION, an unexpected stapling could occur, if contact element is allowed to re-contact against the workpiece or the other surface under the influence of recoil.
