Bit of a newbie in the wheel loader world, but recently purchased a CAT 930h wheel loader. I have attached a photo of the joystick in this machine, it has a gear selector switch as well as a 3rd function aux switch. What is the trigger on the back of the joystick for, the manual mentions nothing about it and cannot find anything online. T 930
Please post a Serial Number to give us a bit of a clue.

Thanks for the Serial Number. Could you post a photo of the joystick on your particular machine please.
Thank you for that. What is the Cateprillar Publication reference of the manual you are using.? It sounds to me as though it is not the correct one for your machine. when it was originally sold your particular loader is equipped with the (optional) Work Tool attachment comprising of a carriage and forks in addition to the bucket, plus and AUX hydraulic function for other work tools. I think the text below should explain it. Optional Work Tool Joystick Control (C) Auxiliary Hydraulic Control (thumb wheel) (E) Joystick Control (L) Transmission Direction Control Switch (If Equipped) (M) Auxiliary Operating Mode Switch (Third function) Standard Work Tool Mode - With the Auxiliary Operating Mode Switch (M) in this position, the system provides intermittent flow for the auxiliary hydraulic function. In this mode, the detent function is disabled. The oil flow is proportional to the displacement of the thumbwheel (C). Roll the thumb wheel (C) upward in order to provide flow to the right supply line. The flow will increase the further the thumbwheel is moved. Roll the thumbwheel (C) downward in order to provide flow to the left supply line. The flow will increase the further the thumbwheel is moved. Continuous Flow Mode - With the Auxiliary Operating Mode Switch (M) in this position, the system provides continuous flow for the left hand auxiliary hydraulic function. In this mode, the detent function is engaged. The thumb wheel (C) functions as an on/off switch. Roll the thumb wheel (C) downward in order to provide continuous flow to the left supply line. Roll the thumb wheel (C) in either direction in order to stop the flow.
