b. Unit runs unevenly, operating pressure too low or stops even:
→
check position of fuel tap (158) (picture 4)
→
check diaphragms (104; 105) in air intake valve (101)
→
check carburettor gaskets for leakage
→
check level in fuel tank
→
check, if residues at end of resonator (266) by looking carefully into the
resonator from a distance of min. 2 m and keep unit running .
Wear protective goggles !
→
check diaphragms (92) of the valve (90) at air funnel (112) for
damage and correct seat. At the same time check gaskets (94; 95)
→
check swirl vane (116) and mixing chamber (114) for combustion
residues
→
Adjust fuel dosage (143). Turning counter-clockwise or to the left increases
the fuel flow.
Attention: Do not unscrew regulating needle (143) too far! (picture 9)
c.
If unit generates insufficient fog or none at all:
→
Decompression screw (59) is not tightened
→
Leakage of tank cap (2). Take out gasket (4), turn around or replace if
necessary
→
Is fog solution socket (57) clogged?
→
Is dosage nozzle (250) clogged?
→
Feed pressure in solution tank (1) might be too low. Check valves (90) and
diaphragms (92) for correct seat.
→
LED (212) to be checked and if it is not alight, the pressure in the carburettor
is too low; the solenoid valve cannot open
→
Disconnect solution pipe (55) from solution tap (50) and at fog solution socket
(57) and check solenoid valve (240) for free passage
→
Check solution guide system for free passage:
1. Loosen solution pipe at the solution tap (50), turn the tap open, solution must
flow. If not, unscrew filter (45) after loosening glass cap (46) turning counter-
clockwise, check and clean if necessary.
Beforehand, decompress solution tank (1)!
2. If paragraph 1 is put in order, try again to fog. If without success:
3. Loosen screw of the solution pipe (55) at solenoid valve (240) or hollow screw
(250) respectively and counterhold with second spanner SW 17 (picture 2).
Check for solution flow and, if available, assemble again.
4. Loosen hollow screw (250) at solenoid valve (240). After pressing button
210) and turning solution tap (50) to the position „open“, check if solution
flows.
