Protection of Environment
Be aware of your surroundings
• Watch out for animals which may be within
your work area
• Be aware that noise is harmful to the envi-
ronment. Inquire about and respect possible
local rest periods.
Operating Hints
- Approach the target object with the engine
at idling speed. Accelerate to full engine
speed, then open formula on-off tap.
- No other persons should be present within a
circle of 15 meters from the operator. Watch
out for children and animals. Objects carried
by the air stream can deflect and injure near-
by persons.
- Never operate on unstable ground watch out
for any obstacles such as tree stumps, tree
roots, ditches etc.
- Take special care while working along slopes.
- Never touch a hot exhaust.
MAINTENANCE AND CARE
Air Filter (Fig. 9)
The air filter separates and retains dirt before
the air reaches the combustion chamber. This
reduces engine wear.
Regular maintenance increases engine life.
Check and clean the air filter
For daily cleaning tap the air filter against an
object or use an air gun.
With heavy dust conditions and for normal
weekly check thoroughly clean the filter and
replace filter if damaged.
Cleaning of air filter
The filter fitted by the factory has been trea-
ted with special oil.
Suitable air filter oil is available in 200 ml
spray cans, part no. 00 83 177, from our parts
service network.
To extend the maximum performance and ser-
vice life of your engine, the recommendations
and instructions of the manufacturer should
be adhered to.
Clogged air filters cause performance loss and
increased fuel consumption.
This leads to a higher toxin level in the
exhaust gas and also makes starting more
difficult.
When the machine is used all day, the air
filter should be cleaned daily. In severe dust
conditions clean more often.
Simply tapping the filter against an object is
the best method of cleaning.
Wash a heavily soiled filter in non-flammable
cleaning solvents (warm soapy water). The fil-
ter should be completely dry before applying
filter oil. Immediately replace damaged filter
parts. Warranty claims cannot be accepted for
damaged engine parts caused by improper
care and maintenance.
For removal of the air filter (Fig.9, Pos.1), remove
filter cover. Remove filter cover screw (Fig.9,
Pos.2).
When re-fitting, ensure the filter is positioned
and seated properly.
Fuel tap
Remove the fuel cock at regular intervals to
clean the fuel strainer. - Make sure to keep
the vent hole of the fuel tank cap open at all
times.
Formula Tank Lid
Watch seal of the spray tank lid and service
by lubricating the rubber gasket inside the lid.
Failing this, pressure built-up in the container
is impaired and dosage of emission becomes
irregular.
Liquid Tap
Maintain the tap on a regular basis and apply
oil or grease. To disassemble the tap, twist the
upper part 1/4 turn to the left (anti-clockwi-
se). Apply oil or grease to the valve stem and
o-ring, than re-assemble. Replace o-ring if
required.
Spark Plug
The correct spark plug with thermal range 200
is available under the following brands:
BOSCH
W
8AC
CHAMPION L88 / L288 or similar.
The correct electrode gap is 0.5mm.
Caution: Check the plug after eve-
ry 50 operating hours and replace
if electrodes are worn.
