8INSTALLATIONSelecting compressor (Fig. 1)The air compressor must comply with the requirements ofEN60335-2-34.Select a compressor that has ample pressure and airoutput to assure cost-efficient operation. The graph showsthe relation between nailing frequency, applicablepressure and compressor air output.Thus, for example, if nailing takes place at a rate ofapproximately 37 times per minute at a compression of7.0 kgf/cm 2 G (100 PSIG), a compressor with an air outputover 2 ft3 /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 hose (Fig. 2)Use an air hose as large and as short as possible toassure continuous, efficient nailing operation. With an airpressure of 5.0 kgf/cm2 G (70 PSIG), an air hose with aninternal diameter of over 6.5 mm (1/4”) and a length ofless than 20 m is recommended when the intervalbetween each nailing is 0.5 seconds. Air supply hosesshall have a minimum working pressure rating of10.7 kgf/cm 2 G (150 PSIG) or 150 percent of themaximum pressure produced in the system whichever ishigher.CAUTION:• Low air output of the compressor, or a long or smallerdiameter air hose in relation to the nailing frequencymay cause a decrease in the driving capability of thetool.Lubrication (Fig. 3)To insure maximum performance, install an air set (oiler,regulator, air filter) as close as possible to the tool. Adjustthe oiler so that one drop of oil will be provided for every30 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 of timesafter pneumatic tool oil is introduced. (Fig. 4)FUNCTIONAL DESCRIPTIONCAUTION:• Always disconnect the air hose before adjusting orchecking function on the tool.Adjusting depth of nailing (Fig. 5)To adjust the depth of nailing, turn the adjuster. The depthof nailing is the deepest when the adjuster is turned fullyin the A direction shown in the figure. It will becomeshallower as the adjuster is turned in the B direction. Ifnails cannot be driven deep enough even when theadjuster is turned fully in the A direction, increase the airpressure. If nails are driven too deep even when theadjuster is turned fully in the B direction, decrease the airpressure. Generally speaking, the tool service life will belonger when the tool is used with lower air pressure andthe adjuster set to a lower depth of nail driving.CAUTION:• Always disconnect the hose before adjusting the depthof nailing.Hook (Fig. 6)CAUTION:• Always disconnect the hose from the tool.• Never hook the tool at high location or on potentiallyunstable surface.The hook is convenient for hanging the tool temporarily.Adjusting the shingle guide (Fig. 7 & 8)The 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 the projectionsof the contact element depressing the bottom of theprevious row of the shingle. Slide the adjusting plate upagainst the bottom of the exposed shingle and turn thelever counterclockwise to lock the adjusting plate.ASSEMBLYCAUTION:• Always disconnect the air hose before carrying out anywork on the tool.Loading nailer (Fig. 9)Select nails suitable for your work. Depress the latch leverand 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 to thecorresponding graduation increment marked on themagazine. If the tool is operated with the coil support plateset to the wrong step, poor nail feed or malfunction of thetool may result. (Fig. 10)Place the nail coil over the coil support plate. Uncoilenough nails to reach the feed claw. Place the first nail inthe driver channel and the second nail in the feed claw.Place other uncoiled nails on feeder body. Close themagazine cap after checking to see that the nail coil is setproperly in the magazine. (Fig. 11)Connecting air hose (Fig. 12)Slip the air socket of the air hose onto the air fitting on thenailer. Be sure that the air socket locks firmly into positionwhen installed onto the air fitting. A hose coupling must beinstalled on or near the tool in such a way that thepressure reservoir will discharge at the time the air supplycoupling is disconnected.OPERATIONCAUTION:• Make sure all safety systems are in working orderbefore operation.1. To drive a nail, you may place the contact elementagainst the workpiece and pull the trigger, or (Fig. 13& 14)2. Pull the trigger first and then place the contact elementagainst the workpiece.
