Install the start switch
1. Clamp the torch lead in place, with the white wires facing up, to keep the lead from moving.
2. Connect the new start switch by pushing the mating plug into the socket.
3. Press the new start switch onto the 2 mounting posts in the handle. See Figure 17.
4. Verify the wires are correctly positioned around the 4 posts in the handle, as shown in Figure 17. Make sure the wires
do not run over the gas tube or across the slot for the gas tube fitting’s flange. All 4 wires must sit behind the gas
tube in the handle.
