3.5 Clean and lubricate the tape cutter
3.5.1 Tape cutter for the fixed feeder bank with 60 feeder positions
Step 1 Clean the following parts of the tape cutter before lubricating it.
Linear guide bearing and the linear guide rail
Although the cleanable areas are limited, remove old grease with a scraper and then clean
the area with cloths.
Cutter blades
Warning:
Be sure to wear cut-resistant leather gloves when cleaning the cutter blade. Otherwise you may get
injured.
Dip a used toothbrush or a brush in isopropyl alcohol and clean the cutter blade. Scrape off
the sticky dirt with a scraper. Then wipe the blade with cloths or cleaning paper soaked with
isopropyl alcohol.
Area around the tape cutter
Remove the dust or fallen objects such as components with a vacuum cleaner.
Step 2 Check the condition of the cutter blades.
Check the cutter blades for chipping, wear and loosening of fixing screws.
Note:
Should there be any problem, blade replacement is required. If you have a spare blade set,
replace the blades. If not, explain the situation to the customer and be sure to replace the
blades soon.
Step 3 Check the clearance between the cutter blades.
Measure the clearance between the blades of the tape cutter (for the fixed feeder bank with
60/ 24/ 14 feeder positions) to see if it is appropriate. Make a note of the measured result on
the Check sheet.
Tip:
If the blade-to-blade clearances are improper, faulty conditions including premature blade
wear, inability to cut waste tapes, tape jamming or other may result. In this case, verify and
adjust the installation condition of the blades. See “SI1109005E = YS machine tape cutter
blade replacement” for the details.

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.
