[. . . ] Always wear safety glasses to protect your eyes from dust or nail 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. [. . . ] Use an air hose as large and as short as possible to assure continuous, efficient nailing operation. 7 kgf/cm2G (150 PSIG) 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 nailing frequency may cause a decrease in the driving capability of the tool. 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 7. 0 kgf/cm2G (100 PSIG) , a compressor with an air output over 2 CFM ( 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. Adjust the oiler so that one drop of oil will be provided for every 50 nails. 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. Load the same kind, size and uniform length of nails when loading nails in the magazine. The depth of nailing is the deepest when the adjuster is turned fully in the A direction shown in the figure. It will become shallower as the adjuster is turned in the B direction. If nails cannot be driven deep enough even when the adjuster is turned fully in the A direction, increase the air pressure. If nails are driven too deep even when the adjuster is turned fully in the B direction, decrease the air pressure. Generally speaking, the tool service life will be longer when the tool is used with lower air pressure and the adjuster set to a lower depth of nail driving. [. . . ] Also, route the hose away from obstacles which it may become dangerously caught on during operation. Hoses must also be directed away from sharp edges and areas which may lead to damage or abrasion to the hose. To maintain product SAFETY and RELIABILITY, repairs, any other maintenance or adjustment should be performed by Makita Authorized or Factory Service Centers, always using Makita replacement parts. Use protección para los oídos para protegerlos contra el ruido del escape, así como también debe usarse protección para la cabeza. [. . . ]
