Loosen the blade se cur ing bolt fully
with the hex wrench. Keep the back
edge of the blade fit ting into the roller
and in sert the blade be tween the blade
clamp and the slider as far as it will go.l
Make sure that you are in sert ing the
blade into the proper po si tion.
Fit the pin on the slider in the hole in the
blade shank.

The hole in the blade shank will be aligned
with the pin on the slider when the blade
shank hits against the spring pin on the

Tighten the bolt se curely while
mak ing sure that the blade will not
be ex tracted even though you try to
pull it out.

If you tighten the bolt with out the pin
on the slider fit ting prop erly in the
hole in the blade shank, the pin or
the blade shank will be dam aged.

ex tracted un ex pect edly dur ing
