13. Operating and maintenance
instructions
13.1 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
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 “13.5 Shutdown and storage”.
13.2 Engine components
When performing adjustments or maintenance
work on engine components, always carefully
follow the specifications in the separate operating
instructions for the engine. Only perform work
which is actually described in the instructions and
which you feel able to carry out. All other work
must only be performed by an authorised
specialist workshop, who will also be happy to
assist with any queries.
The following work is the minimum level of work
which must be performed on a regular basis in
accordance with the specifications in the operating
instructions for the engine:
x Check the idling position and readjust the idling
stop screw as required.
No drive must be delivered to the cutting tool
when the engine is idling.
x Clean the air filter and check the filter element.
x Check the silencer before starting work and
before starting the engine to check it is in
perfect condition.
Never touch the silencer when it is hot.
x Check the spark plug to make sure that the
electrode gap is correct and the electrodes are
not excessively burned off.
x Check the fuel tank breather and the fuel filter.
13.3 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 12.3 "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 12.3 "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.
