11.4 Excess spray chemical / Completing
spraying operation
Stop the engine of the high pressure sprayer as
soon as air is pumped through the nozzle (this can
be heard and seen by the formation of fog like
spray drift). At that point the remaining spray
chemical in the tank is less than 340 ml. Unless
you want to refill the tank and continue with the
spray operation, dilute the remaining spray volume
with 2 litres of water. Apply the dilution over the
already treated area.
Never operate the engine without liquid in the
spray tank. The pump will suffer damage if
operated dry.
After finishing the spray operation, stop the engine
by pressing the stop button (9) until the engine
stops. Let the engine cool down. Empty and clean
the machine according to section 12.4 "Emptying
and cleaning of chemical tank". Thoroughly wash
face and hands with water and soap. Remove the
work clothing after spraying. Clean work clothing
regularly.
Note:
After extended operating periods of the high
pressure sprayer, the engine and some parts
(such as the muffler) around the engine can get
very hot. To prevent any consequential damage
we recommend the running of the engine at idling
speed for a short time after the engine has been
used at full speed for longer periods before the
engine is shut down as described.
12. Operating and maintenance
instructions
12.1 General operating and maintenance
instructions
The maintenance and the repair of modern
machines as well as their safety-relevant
assemblies require qualified specialised training
and a workshop equipped with special tools and
test equipment. Consequently the manufacturer
recommends that all tasks not described in these
operating instructions be carried out by a
specialised workshop. That specialist has the
required training, experience, and equipment at his
disposal, to provide you with the most cost-
effective solution for such work. He will provide
additional help in word and deed.
After a running-in time of app. 5 hours, all
accessible screws and nuts (except the carburettor
ENGLISH 14
adjusting screws) must be checked for tightness
and they must be retightened, if required.
Always check the engine driven high pressure
pump prior to commencing work to ensure the
complete machine is in good and safe working
order.
It is best to store the equipment in a dry, safe
location with a full fuel tank. There should be no
open flame or similar nearby. When not using the
equipment for longer periods, (longer than four
weeks), see chapter "12.5 Shutdown and storage".
12.2 Checking output volume of spray
chemical
Check the output volume of the machine (l/min) to
ensure the measured data agrees with the spray
volume stated in section 11.3 "Spray nozzle /
Output volume". This should be done at least once
per year, preferably at the beginning of the spray
season.
Fill the liquid tank with water to the maximum fill
mark on the tank. Operate the sprayer for exactly
one minute at 10 bar pressure.
Stop the engine and measure the volume of water
required to refill to the max. fill mark.
The measured volume is the output of the machine
in l/min at 10 bar operating pressure. The
ascertained data should not vary by more than
10% from the data provided in section 11.3 "Spray
nozzle / Output volume".
If the measured volume is too small, the nozzle
may be partially blocked. Clean the nozzle and
repeat the test procedure.
If the measured volume is too large, the nozzle
may be damaged or worn. Replace the old nozzle
with a new nozzle
(Part No. 06 10 03 12 00 503 - Nozzle
06 10 03 12 00 502 – Swirl plate).
While checking the output volume also check the
nozzle for even output over the full spray pattern.
