O-Ring Removal Tool
Replacing the Torch
1. Loosen the knurled nut and firmly grasp the torch and push it slowly into the
torch mount. Rotate the torch so that the stripe on the torch lines up with the
index mark on the torch mount and the guide pin on the torch coupler. Firmly
tighten the knurled nut. See the following figure.
Note
The dark blue torch O-ring (Part No. N0791334) on the outside of the torch
and the dark blue O-ring on the outside of the injector adapter (Part No.
N0791333) should be replaced after 300 insertions. Use the O-ring
removal tool (Part No. 09220410) to remove. See Figure 5-7 and Figure 5-
8.
