WarnInG:
• Turn off air and coating materials to the gun and release pressure by triggering
the gun before disassembling, cleaning or servicing.
• Be careful when disassembling the spray gun it contains sharp parts.
• If unsure, please take the spray gun to a qualified technician for repair.
• Pour remaining paint into another container and then clean the paint
passages and air nozzle. Spray a small amount of thinner to clean paint
passages, incomplete cleaning will cause adverse pattern shape and
particles. Always clean spray guns thoroughly, immediately after use. If using
two-component paint, ensure the gun is cleaned thoroughly, immediately after use.
• Clean other sections with a brush soaked with thinner and waste cloth.
• Clean paint passage fully before disassembly.
• Remove fluid nozzle after removing fluid needle set or while keeping fluid
needle pulled in order to protect seat section.
• While keeping fluid needle packing set by hand, then tighten gradually by
spanner.
- Adjust packing set while pulling trigger and watching movement of fluid
