This document provides technical specifications and details about a pneumatic stencil cleaner. It can clean stencils and other items up to 29 inches in size using compressed air and liquid cleaning. It has a three-stage filtration system to filter particles down to 1 micron. Maintenance involves replacing filters every 1-2 months and cleaning the liquid storage tank. The pneumatic design means it operates without electricity for safety.

15. • Open the door at the bottom right of the device, remove the filter cartridge with a wrench and take out
the built-in old filter element, and install a new filter element after cleaning. Note: When replacing the filter
element, it is necessary to wear industrial rubber gloves to drain all the liquids in the internal pipes, storage
tanks and filters of the equipment. So as not to pollute the newly replaced filter element, and fail to achieve
a good filtering effect.：
•Unscrew here with a special wrench
• Remove the filter cartridge, tighten it clockwise, and loosen it counterclockwise. After
replacing the new filter element, install it and tighten it. Then start the machine, check if
there is any liquid leakage in the filter, if so, tighten it again until there is no leakage.
To replace the filter element:

Unscrew here with a special wrench

16. tank cleaning
• Clean the filter box and replace the filter.
• Open the door on the lower right side of the device, and unscrew the lid of
the liquid storage tank. There is a filter screen inside the liquid storage tank.
Take off the filter bag, clean the filter bag inside and the sundries at the
bottom with cleaning solution (when changing different cleaning solutions,
you need to take out the filter bag, take out the filter bag and rinse it with
clean water before using it) and then Put it back in place. Finally install the
reservoir cover and close the door. As shown below:
