TO INSTALL THE AUGER

If the auger is kinked or bent: straighten it by
plying it over the upper leg.
FIGURE 87. FIGURE 88.
TAKE CARE THAT THE AU-
GER DOES NOT UNROLL !
If you can't straighten the auger, cut out the
kinked part.
Then braze the auger according to our instruc-
tions.
! KINKS OR DENTS WEAR OUT THE TUBES !
DANGER
AUGER BRAZING
FIGURE 89. FIGURE 90.
Always use hard solder. We recommend a bronze, flux-coated rod.
The joint must be well filled. Avoid sharp edges or rough corners :
these wear out the tubes. Braze at low temperature.
Allow the joint to air cool. Rapid cooling makes the joint brittle and
breakable. Remove alle sharp welding seams that could wear out the
tube from the outer edges of the auger !
