9. Turn the grinding switch on and grind off the flash around weld. Use light
grinding pressure only to avoid stalling the grinding motor or causing a thin spot
which would weaken the blade at the weld. Hold the blade slightly curved, as
shown in Fig. 5 to avoid grinding other than where the flash is found in the weld.
10. Repeat STEP 7 for final annealing.
11. Jaw plates should be kept clean. Wipe flash from jaws after every weld as
accumulations will destroy alignment. Never file jaw plates.
