provided with it. Before cleaning, make sure air is released from air
passages.
_ Only use suitable cleaner designed for your spray gun washer.
_ Make sure that the equipment is dried immediately after cleaning.
_ Do not leave spray guns inside spray gun washer, after cleaning.
Cleaner vapour can damage packings and cause corrosion inside gun
body.
_ Do not leave spray guns soaking in cleaner.
_ Securely ground washer equipment.
Use of cleaner with waterborne coatings, can increase PH level, especial-
ly after several cleanings. Please, replace the cleaner regularly in order to
always ensure the best spray gun performance.
_ Make sure that the PH level of cleaner does not exceed the limit.
PH level: 6.0~8.0 (but only during cleaning).

- If you tighten fluid needle packing set (3) too much, fluid needle set
(2-2) will not move smoothly, resulting in paint leakage from tip of fluid
nozzle (2-1).
- Try to adjust it carefully while pulling trigger and confirming movement
of fluid needle set (2-2).
- If you tighten it too much, repeat operation.
a.Disassemble fluid nozzle (2-1), while
keeping fluid needle (2-2) pulled
(triggering) in order to protect its
seat section.
b.Disassemble fluid needle set (2-2).
(only when strictly necessary)
d. Fluid needle packing set (3), must
