jGun22 JETYD Operations ManualFirst use of Dual Speed jGunYou have the FASTEST Air Tool in the world in your hands. Pleaseread the Operating Instructions and follow the advice given herein.The jGUN has a high-speed mode when the handle is pushed forwardby the operator and a low speed mode when the handle is pulledback.To tighten flanges and casings requires first parallel joint closure.This can be assured with PRE-TORQUE!PRE-TORQUE is derived by pin-connecting the right sized impactsocket on the square drive of the tool. Make sure the socket is ingood condition.DO NOT CONNECT THE REACTION ARM SUPPLIED WHENPRE-TORQUING!Engage all nuts to the bolt ends with one thread. Push the handleforward as you pull the trigger and run down all nuts in a criss-crossmanner. To move the tool from one nut to another, switch from “T” to“L”, pull the trigger temporarily and take off tool. This does notloosen the nut. Switch back to “T” to continue.When all nuts are Pre-Torqued, take off the Socket, place ReactionArm on the tool spline [this will automatically set tool into the low-speed mode], pin-connect the socket, set the tool to “T”, place on thenut with the reaction arm sticking outwards so that when you pull thetrigger the reaction arm automatically abuts against the adjacent nutand the other one is tightened to the torque preset on the FRL.PLEASE NOTE: The run-down and run-off Speed of the tool is notfaster than that of an impact gun. Nevertheless, it takes getting usedto. So, please take your time initially and use common sense.It won’t take long for you to feel at ease with your tool.
