[. . . ] Always wear safety glasses to protect your eyes from dust or staple injury. 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. [. . . ] Keep fingers away from trigger when not driving fasteners to avoid accidental firing. The graph shows the relation between stapling frequency, applicable pressure and compressor air output. Thus, for example, if stapling takes place at a rate of approximately 60 times per minute at a compression of 100 PSIG (6. 8 bar) , a compressor with an air output over 3 ft3/minute is required. 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. Use an air hose as large and as short as possible to assure continuous, efficient stapling operation. Air supply hoses shall have a minimum working pressure rating of 150 PSIG (10 bar) or 150 percent of the maximum pressure produced in the system whichever is higher. CAUTION: Low air output of the compressor, or a long or smaller diameter air hose in relation to the stapling frequency may cause a decrease in the driving capability of the tool. Adjust the oiler so that one drop of oil will be provided for every 50 staples. When an air set is not used, oil the tool with pneumatic tool oil by placing 2 (two) or 3 (three) drops into the air fitting. For proper lubrication, the tool must be fired a couple of times after pneumatic tool oil is introduced. CAUTION: Always disconnect the hose before carrying out any work on the tool. Secure the hook on the tool with the provided screw using either of two holes in the hook as shown in the figure. To adjust the depth of stapling, loosen the bolt by using the hex wrench provided with the tool and then slide the depth adjusting plate up or down. If staples cannot be driven deep enough, slide the adjusting plate in the direction of arrow as shown in the figure. Always return the pusher slowly and gently while holding it with a hand. Pull the pusher to the rear of magazine and hook the groove in the pusher on the lock pin. If the staples are driven too deep, slide the adjustinhg plate in the direction of arrow as shown in the figure. CAUTION: Make sure all safety systems are in working order before operation. Pull the trigger first and then place the contact element against the workpiece. With the lock pin depressed, return the pusher slowly and gently to the original position. [. . . ] If moisture is allowed to enter the tool, It may result in poor performance and possible tool failure. It is warranted to be free of defects from workmanship and materials for the period of ONE YEAR from the date of original purchase. Should any trouble develop during this one year period, return the COMPLETE tool, freight prepaid, to one of Makita's Factory or Authorized Service Centers. If inspection shows the trouble is caused by defective workmanship or material, Makita will repair (or at our option, replace) without charge. [. . . ]
