If the blade-to-blade clearances are out of range
Explain the situation to the customer that the extra time is required for the adjustment and
get their permission to adjust the clearances. Consult with YAMAHA for information about
the adjustment procedures.
How to set the shims
When adding or decreasing shims to adjust the clearance between the blades, bear the
following in mind.
<Note for the adjustment>
Do not insert more than two (2) shims between the lower blade and the base plate.
If the clearance between the lower blade and the base plate cannot be adjusted
with the shims, insert shims between the base plate and the linear guide bearings.
Step 4 Feed grease from the grease nipples of the linear guide using a grease gun.

Step 5 Lubricate the cutter blades.
Apply a thin layer of grease (NSL) to the upper surface of the two blades with a brush, and
apply AZ turbine oil (Syringe oil) to the edge of the blade. Drop a small portion of turbine oil on
the blade and spread it with a brush.
Warning:
NEVER apply grease on the tape cutter with your fingers. Serious injury may result.
Figure 54
Step 6 Remove excess grease from the cutter unit.
Warning:
Wiping grease off the blade by hands is very hazardous. To avoid injury, fold cleaning cloth to make it
thick and use it for wiping grease off the blade so that your fingers won’t touch the blade directly.
Step 7 Check the movement of the tape cutter.
Insert a screw into a tapped hole of the plate in front of the blade. Move the screw to and fro to
move the cutter unit and check if the blades move smoothly.
