The graphshows the relation between nailing frequency, applicablepressure and compressor air output.Thus, for example, if nailing takes place at a rate ofapproximately 30 times per minute at a compression of0.59 MPa (5.9 bar), a compressor with an air output over30 liters/minute is required.Pressure regulators must be used to limit air pressure tothe rated pressure of the tool where air supply pressureexceeds the tool's rated pressure. Failure to do so mayresult in serious injury to tool operator or persons in thevicinity.Selecting air hoseFig.1Use an air hose as large and as short as possible toassure continuous, efficient nailing operation. With an airpressure of 0.49 Mpa (4.9 bar), an air hose with aninternal diameter of over 6.5 mm and a length of lessthan 20 m is recommended when the interval betweeneach nailing is 0.5 seconds.CAUTION:• Low air output of the compressor, or a long orsmaller diameter air hose in relation to the nailingfrequency may cause a decrease in the drivingcapability of the tool.LubricationFig.2To insure maximum performance, install an air set (oiler,regulator, air filter) as close as possible to the tool.Adjust the oiler so that one drop of oil will be provided forevery 30 nails.When an air set is not used, oil the tool with pneumatictool oil by placing 2 (two) or 3 (three) drops into the airfitting. This should be done before and after use. Forproper lubrication, the tool must be fired a couple oftimes after pneumatic tool oil is introduced.Fig.3FUNCTIONAL DESCRIPTIONCAUTION:• Always disconnect the air hose before adjusting orchecking function on the tool.Adjusting depth of nailingFig.4To adjust the depth of nailing, press the knob toward thenose tip and turn the adjuster so that the arrow above theadjuster will point to the number indicated on the adjuster.The depth of nailing is the deepest when the arrow pointsto the number 1. It will become shallower as the arrowpoints to higher number. The depth can be changed inapprox. 0.8 mm increments per graduation. If nails cannotbe driven deep enough even when the arrow points to thenumber 1, increase the air pressure. If nails are driven toodeep even when the arrow points to the number 9,decrease the air pressure. Generally speaking, the toolservice life will be longer when the tool is used with lowerair pressure and the adjuster set to a lower number.Adjusting the shingle guideFig.5Fig.6The shingle guide is designed for consistent shingleexposure. Place shingle in desired position.Turn the lever clockwise to release the adjusting plate.Reset the tool on the exposed shingle with theprojections of the contact element depressing thebottom of the previous row of the shingle. Slide theadjusting plate up against the bottom of the exposedshingle and turn the lever counterclockwise to lock theadjusting plate.ASSEMBLYCAUTION:• Always disconnect the air hose before carrying outany work on the tool.Loading nailerFig.7Select nails suitable for your work. Depress the latchlever and open the magazine cap.Lift and turn the coil support plate so that the arrow withnail size indicated on the coil support plate will point tothe corresponding graduation increment marked on themagazine. If the tool is operated with the coil supportplate set to the wrong step, poor nail feed or malfunctionof the tool may result.
