Cleaning The Cylinder Section - Ryobi 3302H Operation Manual

Chapter 1 Maintenance after the Printing
3. Cleaning the Cylinder Section
A
WARNING
Stop the crawl operation before cleaning. Failure to follow this instruction may result in a serious injury.
The materials that are used with the press have a high degree of acidity and alkali which have a negative effect on the
press. The use of these strong chemicals may cause the metal parts to corrode or rust, so proper maintenance of the press
is very important after finishing the operation for the day. Because the cylinder section greatly influences the printing
quality, proper maintenance should be done on it every day.
1)
Clean the plate cylinder.
Maintenance Edition - 6
Take off the plate and under sheet from the plate cylinder after printing is
finished. Wipe off any stains such as ink, etching solution, and plate cleaner
on the plate cylinder surface with a cotton rag containing water and
cleaning solution.
Also, when using the gauge film with the plate cylinder, take off the
gauge film and clean the plate cylinder at least once a month.
«NOTICE»
1. Do not use plate cleaner to clean the plate cylinder. When cleaning
the plate, be careful that the plate cleaner does not adhere on the
plate cylinder surface.
If the plate cleaner adheres on the plate cylinder surface, wipe it off
with a cotton rag containing water and cleaning solution immediately.
2. When using the gauge film with the plate cylinder, clean the cylinder
surface well and dry it completely before mounting the gauge film.
Also, mount the gauge film so that it contacts the entire surface of
the cylinder. If there is any clearance between the film and cylinder,
water, etching solution, and the other chemicals will enter into the
clearance and rust will form.
3. When the hydrophilic properties of the plate surface cannot be kept,
wipe off any ink and oil with a cotton rag containing chrome roller
cleaner. Then wipe off the chrome roller cleaner completely with a
cotton rag containing water.
