[. . . ] 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. There may be local regulations concerning noise which must be complied with by keeping noise levels within prescribed limits. Do not play with the contact element: it prevents accidental discharge, so it must be kept on and not removed. [. . . ] 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 40 times per minute at a compression of 6. 0 kgf/cm2G (85 PSIG) , 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. Adjust the oiler so that one drop of oil will be provided for every 30 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 lock the trigger and disconnect the hose before adjusting or checking function on the tool. CAUTION: Always lock the trigger and disconnect the hose before carrying out any work on the tool. 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. To use the hook, simply lift up hook until it snaps into the open position. When not in use, always lower hook until it snaps into the closed position. Return the pusher lever back while keeping the pusher depressed to disengage it from the strip of nails. Pull the trigger first and then place the contact element against the workpiece. [. . . ] If moisture is allowed to enter the tool, It may result in poor performance and possible tool failure. Check regularly to see if there is sufficient pneumatic oil in the oiler of the air set. Keep the air hose away from heat (over 60°C, over 140°F), away from chemicals (thinner, strong acids or alkalis). Also, route the hose away from obstacles which it may become dangerously caught on during operation. [. . . ]
