Replacing the valve assembly
Tools needed
Fig. 6.6/1:
1. Let the device heat up. Continue activating the trigger until the tank is completely emp-
ty.
2. With the cover closed undo the fixing screw (E1) of the lever (E2) with the hexagon
socket spanner size 3. Remove the lever and carrier (E3).
3. Undo the screws (E4) with the hexagon socket spanner size 2.5. Remove the cover
casing (E5).
4. Screw the auxiliary screw M4 in to the clamping piece (E7). Release the clamping
screw (E6) with washer with a 2.5 mm Allen key. Carefully remove the clamping piece
with auxiliary screw M4 from the valve housing. Also remove the spring (E8) and the
cone (E9).
5. Decrease the pressure to 1....2 bar. Briefly actuate the trigger. The burst of pressure
ejects the valve (E9) and spring (E10) from the valve housing. Hold a cloth in front of
the opening to catch these (hot!) parts.
6. Fit the new components, cover casing and lever in reverse order.
