Apart from adhering to operating instruc-
tions for power hoe, it is also important to
observe the following maintenance
instructions.
W
Warning: Only do mainte-
nance work with the engine
turned off and spark plug con-
nector removed. Always wear safety
gloves, when working on hoeing tools.
Engine
The oil contained in the fuel mixture lu-
bricates the 2-stroke-engine. Therefore,
there is no engine oil filling opening.
Oil Bath Air Filter
Change oil in oil bath air filter (A/8) after
every 25 operating hours or at least after
3 months. In case of heavy dust
occurence, clean after a few hours –
check for proper condition frequently.
l
Clean air filter and outside surround-
ing parts.
l
Open closing bow and remove oil pot.
l
Remove old oil (dispose of properly)
and clean oil pot.
l
Fill oil pot with engine oil up to oil level
mark (not higher) and re-fit oil pot onto
filter – ensure pot fits tight.
l
After repeated oil change or excessive
dirt in the filter remove the oil pot and
unscrew oil bath air filter. Dip filter into
diesel fuel several times and rinse
thoroughly. Spin dry. Screw air filter back
into place and fill cleaned filter pot with
fresh engine oil. Then re-fit filter pot.
Never wash air filter in petrol, water,
lye or hot liquids.
Cleaning the Cooling System
After operation for an extended period of
time, clogging of plants and dust may
occur in the cooling system. Sustained
operation with the cooling system
clogged lets the engine heat up and
causes damage.
l
Always check cooling-air screen
(B/31) and remove dirt and plant trash
sucked in.
l
Remove fan case at least once per
year, preferably before the season starts,
and clean cooling fins on cylinder and
cylinder head, clean guiding plates and
cooling-air screen, both serving for good
air circulation. For this purpose, contact
your professional agria workshop.
Cleaning Spark Plug and
Setting Spark Plug Gap
After every 50 operating hours
l
remove soot from spark plug elec-
trodes with a steel brush,
l
check the gap between electrodes and
set to 0.6 mm.
Exchange spark plug after approx. 100
hours of operation.
