PERSONAL SAFETY ITEMS 1.  Do not use tool prior to reading the Owner s Manual. 2.  Always wear eye protection that confirms to ANSI requirements (Z87.1) and provides protection against flying particles both from the front and side. Eye protection should be worn by the operator and by others in the work area. Eye protection is required to protect against flying fasteners and debris that could possibly cause severe eye injury. 3.  The employer is responsible to enforce the use of eye protection equipment by the tool operator and all other personnel in the work area. 4.  To prevent accidental injuries: –  Handle the tool with care –  Always assume that the tool contains fasteners –  Always disconnect the air hose from the STINGER™ RT2 when: •  loading nails and/or caps •  performing inspections, maintenance or repairs •  clearing a nail or collated cap jam •  the tool is not in use •  leaving the work area •  moving the STINGER RT2 to another work location •  handing the STINGER RT2 to another person •  storing the tool –  Never point the tool toward yourself or anyone else –  Never engage in horseplay –  Never hold or carry the tool with a finger on the trigger –  Never place a hand or any other part of the body in the fastener discharge area of the tool while the air supply is connected 2 www.nationalnail.com WARNINGS ! AIR SUPPLY AND CONNECTIONS •  Use only clean, regulated compressed air as a power source for this tool. Do not use bottle gases, combustible gases or oxygen as a power source for the tool as the tool may explode. •  Do not use air supply pressures that exceed 120 PSI (8.28 bar or 8.4 kg/mm ). •  Do not exceed the recommended maximum operating air pressure as tool wear will be greatly increased. The air supply must be capable of maintaining the operating air pressure of the tool. Pressure drops in the air supply can reduce the tool s driving power. •  Use a pressure regulator and gauge to allow visual inspection of the air pressure being delivered to the tool. •  Use air hoses that have rated pressures of up to 150% of the maximum pressure that can be generated by the power source. The supply hose should contain 3/8 fittings that will provide quick disconnecting from the male plug on the tool. •  Use quick connect fittings that allow the tool to be unhooked from the air supply quickly and easily. •  Do not use fittings that will not allow the tool to exhaust when the air supply is disconnected. 3 www.nationalnail.com WARNINGS ! OPERATION OF THE TOOL •  Never inspect, maintain, repair, adjust, clear a jam or store the tool with the air connected. •  Never use the tool in proximity of flammable gases or liquids, as some tools will create sparks that can be an ignition source for a fire or explosion. •  Always inspect the safety device for damage and proper operation, prior to operation. •  Never assume the tool is empty of fasteners. •  Never point the tool toward yourself or any other persons. •  Never cycle the tool unless it is in contact with the work-piece. •  Never use the tool as a hammer or wedging device or drop to the floor from any height. •  Never tamper with the safety device or use the tool if the safety device is not functioning properly. •  Use only 1-1/4 STINGER NailPac cap fasteners with the STINGER RT2 Cap Nailer. Never use any fasteners that are not specified for use in the tool. The RT2 holds 1 reel of steel caps (1500 caps) and 1 coil of collated nails (1500 nails). 4 www.nationalnail.com TOOL SPECIFICATIONS Operating pressure 95-105 psi Weight 43 lb.

STINGER RT2 loaded. See next section for operation. 6 www.nationalnail.com OPERATING THE TOOL 1.  Disconnect the air hose from the tool when: •  loading nails and/or caps •  performing inspection, maintenance or repair •  clearing a nail or collated cap jam •  the tool is not in use •  leaving the work area •  moving the tool to another work location •  handling the STINGER RT2 to another person •  storing the tool 2.  For optimal performance, clean and lubricate cap feed moving parts and feed path before each day of use with a dry silicone lubricant. 3/8 NPT male plug (not included) 3.  The STINGER™ RT2 Air Preparation Unit includes an Oil Mist Lubricator for automatic nailer oiling and a Filter Regulator to assist in supply air moisture separation. Recommended pressure setting on the Air Preparation Unit is 95-105 psi. The Oil Mist Lubricator is adjusted at the factory to supply approximately one drop of oil for each fifty nails driven. A screw located at the top of the Oil Mist Lubricator allows for automatic nailer oiling adjustments. Turn clockwise to decrease, and counter clockwise to increase. Oil Mist Lubricator Filter Regulator Unscrew the Oil Mist Lubricator site glass to service with non-detergent pneumatic tool lubricant. The Filter Regulator site glass can be unscrewed or the button on the bottom can be pushed to empty condensation. 4.  Depth of drive for nailing is adjusted primarily with the air pressure regulator; coarse adjustments can be made by moving the Adjustable Wheel Assembly (#136). 7 www.nationalnail.com OPERATING THE TOOL Pushbutton Actuator Hose Holder 4.  The STINGER RT2 is a forward operating tool The caps drag behind the feed system as the tool is pushed forward. Reverse movement may cause jamming. 5.  Feed the air hose through the Hose Holder to aid in air hose management. Toggle Valve (Auto/Manual) 6.  Toggle Valve (Cap Spacing) The STINGER RT2 can be used in an automatic mode or manual mode. Setting the Auto/Manual Toggle Valve to Manual (MAN) requires the Pushbutton Actuator to be depressed each time the user desires to place a cap and nail. With Auto/Manual Toggle Valve in the AUTO position and the push button actuator depressed, a cap will be placed every 9 or 18 inches depending on the Cap Spacing Toggle Valve position selected (9 or 18 .) A 6 pattern is available only with the ten timing button pitch wheel. For 6 spacing, turn all ten timing buttons in and place the toggle switch in the 18 position. The STINGER RT2 is now set to nail on 6 and 9 . Note: Timing buttons should contact ball portion of the valve only. Turning them in too far will result in valve unit damage. This tool is set up for a 9 and 18 pattern. You can change to a 6 and 9 pattern by turning in the acutators with the 5/16 allen wrench supplied with the tool. Check to make sure the actuators do not hit the casing for the roller ball valves as this will damage them. The jam nuts are in a preset position so do not turn jam nuts on the screws. 8 www.nationalnail.com Assembly 137 STINGER™ RT2 SCHEMATIC 44 146 25 40 43 42 39 41 24 (119, 131 on back side of APU) 26 29 38 126 5 28 1 42, 43 7 31 Assembly 136 32 33 7 23 2, 6 22 20 22 17 21 9 www.nationalnail.com Assembly 140 Assembly 139 STINGER™ RT2 SCHEMATIC 57 62 50 63 56 55 54 113 130 112 30 64 61 101 Assembly 145 98 99 100 120 134 65, 66, 67 97 78 115 35 37 120 120 36 69 38 77 70 71 34 17 74 73 14 18 71 19 72 118 116 117 118 Assembly 141 8 76 75 10 www.nationalnail.com STINGER™ RT2 SCHEMATIC 105 104 Assembly 143 105 108 104 110 109 103 102 106 Assembly 144 107 102 103 Assembly 142 87 132 89 95 133 88 89 90 92 96 84 83 94 80 79 81 82 86 93 85 96 95 11 www.nationalnail.com STINGER™ RT2 SCHEMATIC 45 46 91 Assembly 138 47 9 15 16 48 10 120 136 11 12 17 18 19 13 114 66 60 59 111 53 52 101 51 54 55 56 12 www.nationalnail.com STINGER™ RT2 PARTS LIST Location 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 Noted on Schematic x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x NN Item # 610002 136964 652551 650435 136750 136887 136888 136889 136755 136760 136765 136992 136770 136989 136775 136964 136780 136987 136986 136883 136985 136986 136982 136790 136851 136984 136974 136972 136973 136795 136752 136886 136884 136800 136805 136964 136810 136969 136968 136967 136959 136963 136962 136961 136820 136959 136904 136958 136867 136835 136840 136957 Description 1 Hitachi NV50A1 Nailer NV 50 Handle Bolt Hitachi 877851 Feeder Spring Hitachi 877825 Feeder Spring Shaft Exhaust Cover NV 50 Handle Flat Washer Handle Mount Screw 25mm M5 Metric Bolt Trigger Block Trigger Actuator Nail Tray Nail Tray Screw Tray Support Tray Support Bolt Nail Peg Nail Peg Bolt 4” Wheel Wheel Shoulder Bolt Wheel Washer Wheel Lock Washer Adjustable Wheel Bolt Adjustable Wheel Washer Adjustable Wheel Nut Air Preparation Unit (APU) Air Preparation Unit Bracket Air Preparation Unit Bracket Bolt Air Preparation Unit Pad Handle Inlet Air Preparation Unit Bottom Brass Fitting Handle Handle Lock Washer Handle Mount Bolt Handle Flat Washer Cross Mount Spool Hub Spool Hub Bolt Lynch Pin Cap Basket & Cover Cap Basket Bolt Cap Basket Bolt Cap Basket Bolt Cap Basket Flat Washer Cap Basket Lock Washer Magnetic Strip Valve Plate Valve Plate Bolt MAV3 -
