Maintenance

The purpose of the maintenance section is to define the planned maintenance requirements of the
PTR406/PTR406B. Where appropriate maintenance procedures are included.

11.1. Planned Maintenance

The device is designed for a production environment to give trouble free operation provided normal planned
maintenance is adhered to. Maintenance and repair procedures should only be performed by trained personnel.
Improper service and/or repair could result in the safety features being disabled and can also lead to damage that
will not be covered under warranty.

11.2. Cleaning

11.2.1. Clean Mold

Keeping the mold plates clean is vitally important for proper recoat performance and quality. The mold plates should
be cleaned of dirt, dust, or excessive recoat material before each use. Clean the mold plates only with a soft cotton
swab soaked in cleaning solution. Acetone is the preferred solution for cleaning the mold plates. Acetone cleans
more thoroughly than alcohol and will also soften and lift away any cured recoat material. Do not use excessive
scrubbing or scraping action to clean the plates. Give the cleaning solution time (60 to 90 seconds) to soften and
lift any cured material. Excessive cleaning can shorten the life of the mold through damage to the coatings on the
mold plates or chipping of the mold channel.

11.2.2. Check/Clean Fiber Holding Block Inserts

The fiber holding block inserts have a rubber insert that grips the fiber for proof testing. These should be checked
for damage and cleanliness prior to each shift. If the rubber insert is damaged or dirty, the fiber may slip prior to
reaching the maximum proof test level. If required, clean the rubber insert with a cotton swab or lens tissue soaked
in isopropyl alcohol. If rubber insert is damaged it should be replaced.
Note: Do not use acetone to clean the rubber inserts. Repeated cleaning with acetone will damage the rubber.
Note: Do not clean the insert with alcohol when the unit is turned ON. The alcohol could be drawn into the vacuum
system, causing damage.
