ROTATION
In the first blade rotation, flip the lower and upper blades180°, end over end (Pitch Rotation). Then, return them to their
original blade seats.
2. Place the shear upside down so the upper is close
to the ground. Rotate each upper blade, end over
end, 180° (Pitch Rotation). Return them to their
original blade seats. Shim as shown in “Measuring &
Shimming Blade Gaps” on page 28
BLADE ROTATION
Each LaBounty cutting blade has
four usable edges. Each blade can
be flipped and rotated to use all four
edges (see Figure 28 & Figure 29). The
blades must be rotated every 80 hours,
when the blade edge is rounded to
.25” radius or if the blade is damaged.
Some special applications will require a
more frequent blade change schedule.
The blade rotation procedure will help
you get the maximum life from your
LaBounty blades. Blade rotation is a
four step process, which is repeated for
the life of the shear. Every 80 hours, you
will perform one step in the process.
Note: Mark which blade flip you
have performed on the “80-Hour
inspection Checklist” on page 22.
Wear personal protection equipment at all times. This
includes eye protection, hard hat, steel toe shoes,
leather gloves and hearing protection.
Shear blades are very heavy. Do not remove a blade if
its not supported. The blade may fall and cause injury.
