Carburetor Adjustment
The carburetor has been adjusted optimally at the factory.
Depending on the operational altitude of the machine, a re-
adjustment of the carburetor may be necessary.
The carburetor is equipped with 3 adjustment screws:
1. Idling Set Screw
2. Low speed mixture screw (L)
3. High speed mixture screw (H)
The adjustment of the low speed and high speed mixture screws is
limited.
Caution! The carburetor is adjusted for maximum
engine performance. An engine speed counter is
required for correct adjustment!
Engine Adjustment Data
The following data is provided for specialists only!
Basic adjustment data is for the sprayer complete with
assembled spray wand:
Gently turn in the L-adjustment screw and H-adjustment screw as
far as they can go. Do not use force. Unscrew both screws to the
recommended basic setting.
The required engine speed can be adjusted with the set screw
(picture 5). Adjust the engine speed to between 6300 rpm and
6700 rpm, then adjust the carburetor.
Idling speed:
Max. permissible speed:
Caution: Do not adjust to a higher speed as this may
lead to engine or pump damage!
Pump
The pump is maintenance free and is largely unaffected by dry running.
However, to maintain a long operational life for the pump, it is
recommended to always use liquid when running the engine.
The operational life of the pump can be extended if the machine is
operated below max. speed and below max. pressure.
Remedy for possible pump problems:
Loss of pressure indicates a sealing problem with the diaphragm. White
emulsion, visible through the oil drainage plug, will confirm this.
Both diaphragm and oil will have to be replaced to make the pump
operational again.
The Oil fill volume is 60 g or approx. 72 ccm.
The oil quality should be AGIP ROTRA SX 75W90 or similar quality such as:
SHELL AX 75W90 SPIRAX, MOBIL SHC 629 (ISO W615 9).
Air Filter
The air filter prevents dirt penetrating the engine when air is drawn into
the cylinder for combustion. This reduces wear to the engine.
Regular maintenance and replacement of the filter will increase the
service life of your sprayer.
Air filter cleaning
A dirty air filter will reduce engine performance, increase fuel consumption
and increase the level of harmful substances in the exhaust gas. A dirty air
filter also prevents easy starting of the engine.
When the machine is operated for most of the day, the air filter must be
cleaned daily. When used under extreme dusty conditions, clean more
frequently.
For cleaning, simply tap the filter against a hard, flat object.
Under extreme dust conditions, gently clean the filter with compressed air
from inside outwards. Severely clogged or damaged filters should be
replaced. Engine damage caused by an incorrectly maintained filter is not
covered by warranty.
3000 rpm
6300 rpm – 6700 rpm
Spark Plug
The spark plug (thermal value 200) is available in different brands under the
following description:-
BOSCH WSR6F
CHAMPION RCJ-6Y or other brands with same specifications
The correct electrode gap is 0.5mm.
Check the spark plug every 50 hours of operation.
Plugs with worn electrodes have to be replaced.
General Maintenance Hints
After a running-in period of approx. 5 hours, all screws, nuts and
hose connections (with the exception of carburetor mixture
screws) within reach have to be checked for tightness and must be
re-tightened if necessary.
•
Cleaning, repairs or maintenance should only be commenced
after the engine has stopped and the spark plug cap has
been removed.
•
If the lid from the liquid tank is hard to tighten or to remove,
apply some oil to the o-ring inside the lid.
•
Ensure the tank ventilation valve in the lid (picture 1c, 1) is in
good condition and operates perfectly.
General Maintenance Recommendations
•
An authorised service centre should carry out all
maintenance jobs, other than those described in this manual.
Only use original SOLO parts.
•
Do not modify, change or alter the motorized pressure
sprayer – your own personal safety is at stake.
•
Do not maintain or store the machine near an open flame.
•
Regularly check and test the ventilation valve in the lid and
ensure the lid seals correctly and tightly. Always use correct
spark plugs that are in good order. Frequently check the
ignition cable for damage.
•
A motorized pressure sprayer operated without a muffler or
with a defective muffler is a fire hazard and could damage
hearing . Do not touch a hot muffler.
When transporting the pressure sprayer in a
vehicle, ensure the machine is tied down
securely and ensure there are no fuel leaks.
•
When storing the machine for a longer period, always
completely drain the liquid tank, hoses, pump and fuel tank.
Preparation for Storage
The motorized pressure sprayer should be covered and
stored in a dry room not accessible to children.
Special steps to preserve the engine for storage are not
required if our recommended 2-cycle oil "Castrol Supper
TT" has been used.
Empty fuel tank prior to extended storage.
Even though the liquid tank is manufactured from UV-
stabilized material, we recommend storing the sprayer
away from direct sunlight and in a dry room that is
inaccessible to children and animals.
In areas of possible danger of frost, always completely
drain the tank, pump, pressure regulator and hoses.
