Setting the paint needle
•
Step 1:
Remove electro-pneumatic coupling
and product hose to the gun base.
•
Step 2:
Remove rear nut with paint spring
•
Step 3:
To ensure the needle is in contact with
the seat nozzle (rest position), push it with
your finger.
•
Step 4:
Considering that the needle is in
contact with the seat nozzle, the length which
is sticking out the rear nut should be used as
initial position with a caliper (set at “000”).
•
Step 5:
Press the trigger to extreme position
in order to push back the needle to max rear
position.
Keep this position to measure needle‘s stroke.
•
Step 6:
The value must be between 1.8 mm
and 2.2 mm.
If the value is not between the acceptable
range, go to step 7.
If the value is between the acceptable range,
go directly to step 8.
