- 250 bar tighten screw 1236-5 completely.
- 80 bar -unscrew screw 1236-5 to tappet.
-
For pressures in between 80 and 250 bar choose a correspondingly intermediate adjustment of the screw 1236-5
8.6 Round jet regulation
By means of the round jet regulation 1240-U5 atomization air is added to the flat jet cap from the sides.
Clockwise rotation little air - little adjustment to round jet.
Counter clockwise rotation much air - high adjustment to round jet.
8.7 Adjustment of atomization air cap
a.) Put pump pressure at 0 , release trigger 1248-U4 completely - pressure of hose relieves.
b.) Secure spray gun by a 90 ° clockwise rotation of the safety lever 1237-3.
c.) Release lock nut 1248-4 by hand.
d.) Put atomization cap 1248-U2 into required position.
e.) Tighten lock nut 1248-4 well by hand.
