ADJUST BLADE TENSION
Refer to Figure 7
• The blade tension is adjusted automatically by a
spring-loaded blade tensioning mechanism and should
require no frequent adjustment. However, there is blade
tension knob on top of machine for fine tuning of the
blade tension.

contact with the upper and lower blade guides. Raise
the upper blade guide to the top. Move the blade guides
away from the blade.
