wrap roller before going around
the one-way tension roller

beyond the centerline of the
applying roller
Check leg length adjustments
Replace the blade
Increase tape tension by adjusting
the one-way tension roller
Clean and adjust the blade
Make sure the blade is bottomed
out against the mounting bolts
Lubricate the blade oiler pad on
the blade guard
Mount the blade so that the
beveled edge is away from the
entrance of the head
Replace the defective spring(s)
Make sure one-way bearing is
below the surface of the tension
roller. If not, press bearing further
