10. Operating and Maintenance
Instructions
10.1 General operating and
maintenance hints
After a running-in period of approx. 5 hours all
accessible screws, nuts and hose connections
(except for carburettor mixture adjustment
screws) have to be checked and re-tightened if
necessary.
Always check the engine driven high pressure
pump prior to commencing work to ensure the
complete machine is in good and safe working
order.
10.2 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 9.3 "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 9.3
"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.
10.3 Emptying and cleaning liquid tank
To clean the liquid tank drain all residual
chemicals via the drain plug (13) in a suitable
container. If required, tilt the machine slightly to
the side to ensure complete drainage of any
remaining chemical solution. Before tilting the
machine, ensure the fuel tank lid is tight and all
fuel hoses and parts connected with the fuel
system cannot leak fuel. The engine should have
cooled down. Ensure the liquid will not drain
over machine, especially the engine, but directly
in a suitable container.
Drain and thoroughly rinse the liquid tank daily
after use with fresh water. Observe any cleaning
hints provided in the instructions supplied with
the chemical. After cleaning, leave the tank to
dry with the tank lid open.
