If you are installing new Hammers or want to change the
location of the existing Hammers to utilize both
impacting surfaces, slide the Hammers in the Hammer
Frame so that the half-round notch on one Hammer is
located on one side of the Frame and the half-round
notch on the other Hammer is located on the other side
of the Frame. These Hammers must be installed with the
wide bevels facing the web of the Hammer Frame as
illustrated.

direction from the top Hammer and maneuver the Anvil
slightly until it drops into the bottom Hammer.
