MAINTENANCE
The return spring can be adjusted on the foot lever. To
increase the return rate, tighten the hex nuts against the
spring as shown in Figure 15.
Return Spring Tension
The blades can be removed by removing the eight hex
bolts that attach the blades to the castings (see Figure
15).
The moving blade has two cutting edges on it that are
ground with a 2° edge relief. Reverse the blade to expose
the new cutting edge as soon as one edge is dull. The
blade can be sharpened on a surface grinder by grinding
both wide sides of the blade.
The fixed blade has one cutting edge with a 2° edge
relief and a 1° face relief. It can be resharpened on a
surface grinder by grinding the wide side of the blade.

Hex Nuts
Lubricate all pivot and sliding points on this machine
daily. Lightly oil the surface of the blades and other bare
cast iron surfaces to ensure they don't develop rust.
Lubrication
When adjusting gibs, keep in mind that the goal of gib
adjustment is to remove unnecessary slide movement
without causing them to bind. Loose gibs may allow
play in the moving blade resulting in poor cuts on the
workpiece and undue wear on the slide. Over-tightening
will make lowering the foot pedal difficult.
Adjust the three gib screws on each side in small, equal
increments. Test for binding or play after each adjustment
by pushing and pulling the top of the cutter bar.
