Nozzles
From time to time, check the seating of the slider
(Fig. 186/7).
•
To do this, insert the slider into the nozzle
body (Fig. 186/2) as far as possible using
moderate thumb pressure.
Do not insert the slider up to the stop when in a
new condition under any circumstances.

12.16.1 Fitting the nozzle
1. Insert the nozzle filter (Fig. 186/1) into the nozzle body
(Fig. 186/2) from below.
2. Insert the nozzle (Fig. 186/3) into the bayonet nut (Fig. 186/4)
Different coloured bayonet nuts are available for the different nozzles.
3. Insert the rubber seal (Fig. 186/5) above the nozzle.
4. Press a rubber seal into the seat for the bayonet nut.
5. Position a bayonet nut on the bayonet connection.
6. Screw on the bayonet nut up to the stop.
12.16.2 Removing
the
diaphragm valve
if the
nozzle
is dripping
Deposits on the diaphragm seat (Fig. 186/6) can cause the nozzles to
drip after the boom is shut-off. If this occurs, clean the diaphragm in
question as follows:
1. Pull the slider (Fig. 186/7) out of the nozzle body (Fig. 186/2)
towards the bayonet nut.
2. Remove the spring element (Fig. 186/8) and the diaphragm (Fig.
186/9).
3. Clean the diaphragm seat (Fig. 186/6).
4. Reassembly occurs in the reverse sequence.
Note the correct orientation for installing the spring element. For in-
stallation, the stepped, upwards-sloping edges on the left and right of
the housing of the spring element (Fig. 186/10) must slope up in the
direction of the boom profile.
