Next, the threads of the protective housing in which the shear
bolts are threaded is heated using the heat gun. This step de‐

bolt thread, thus allowing the shear bolts to be removed more
easily.
WARNING
By heating the shear bolts, parts of the protective housing will
become extremely hot. Do not burn yourself on this! Ensure
only the shear bolts are heated and not any of the surrounding
parts. Possibly cover these parts.

shear bolts -4-.
