12 ENGLISHSingle sequential actuationPlace the contact element against the workpiece andpull the trigger fully.After nailing, release the contact element, and thenrelease the trigger.► Fig.24CAUTION: Do not place the contact elementagainst the workpiece with excessive force. Also,pull the trigger fully and hold it on for 1-2 secondsafter nailing.Even in the “Single sequential actuation” mode, half-pulled trigger causes an unexpected nailing, when thecontact element re-contacts the workpiece.Contact actuationPull the trigger first and then place the contact elementagainst the workpiece.► Fig.25Nailing on steel plateWARNING: When nailing on the C-shapedsteel, limit the thickness to 2.3 mm (3/32″) orthinner. Otherwise the tool will bounce severely anda nail struck back, causing serious injuries.WARNING: Use hardened nails only for steelplate. Using other purposed nails may cause seriousinjuries.WARNING: When nailing, hold the tool so thatit stands upright to the driving surface. Slantednailing may cause nails to strike back, causing seri-ous injuries.WARNING: Do not use the tool for fasteninga corrugated plate or the C-shaped steel directly.It may cause nails to strike back, causing seriousinjuries.WARNING: Do not use the tool for nailing onceiling or roof.Choose and use nails 10 mm (3/8″) or much longer thantotal thickness of all workpiece to be fastened. Refer tothe table below.Material thick-ness includingC-shaped steel (A)C-shaped steel (B)thicknessNail length (C)9 mm - 22 mm(11/32″ - 7/8″)1.6 mm - 2.3 mm(1/16″ - 3/32″)32 mm (1-1/4″)10 mm - 27 mm(3/8″ - 1-1/16″)38 mm (1-1/2″)14 mm - 35 mm(9/16″ - 1-3/8″)45 mm (1-3/4″)15 mm - 40 mm(5/8″ - 1-9/16″)50 mm (2″)► Fig.26NOTICE: Depending on the hardness andtotal thickness of all workpiece in combination,enough fastening may not be obtained. Nailing onsteel plate with excessive depth may extremelyreduce the fastening force. Before nailing, adjustthe nailing depth properly.NOTICE: Nailing on the steel plate makes thedriver prematurely worn out and it may cause nailjamming. When the driver is worn, replace it with anew one.Nailing on concreteWARNING: Use hardened nails only for con-crete. Using other purposed nails may cause seriousinjuries.WARNING: Do not nail directly on the con-crete or do not fasten directly the steel plate tothe concrete. It may cause concrete fragments to flyoff or nails to strike back, causing serious injuries.WARNING: When nailing, hold the tool so thatit stands upright to the driving surface. Slantednailing may cause concrete fragments to fly off ornails to strike back, causing serious injuries.WARNING: Do not use the tool for fasteningan object to hang something such as sewer pipe.Choose and use nails so that the penetration depth intoconcrete ranges 10 mm (3/8″) - 15 mm (5/8″). Refer tothe table below.Wood thick-ness (A)Nail length (B) Penetration depthinto concrete (C)20 mm (3/4″) 32 mm (1-1/4″) Approx. 12 mm(1/2″)25 mm (1″) 38 mm (1-1/2″) Approx. 13 mm(1/2″)30 mm (1-3/16″) 42 mm / 45 mm(1-5/8″ / 1-3/4″)Approx. 12 mm / 15mm (1/2″ / 5/8″)35 mm (1-3/8″) 50 mm (2″) Approx. 15 mm(5/8″)45 mm (1-3/4″) 57 mm (2-1/4″) Approx. 12 mm(1/2″)50 mm (2″) 65 mm (2-1/2″) Approx. 15 mm(5/8″)► Fig.27NOTICE: Use the tool only for soft concretebuilt up not so long before. Driving nails into hardconcrete may cause nail bending or nailing into insuf-ficient depth.NOTICE: When penetrating into concretedeeper than 15 mm (5/8″), nails may not be drivensufficiently.Cutting linked sheetCAUTION: Always disconnect the air hosefrom the tool before removing the linked sheet.
