44 Power Mower 5400 Edition 02.97
Cleaning Cylinder Head
After every 400 hours of operation take
off cylinder head and remove carbon
deposits on cylinder head and exhaust
tunnel with a steel brush. Afterwards,
clean with soft brush. Exchange head
gasket and reassemble to cylinder head.
Tighten cylinder head screws in turn at
22 Nm. For this purpose, contact your
professional AGRIA workshop.
Cleaning the Cooling System
After mowing 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 grille (G/18)
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 ribs on cylin-
der and cylinder head, clean guiding
plates and cooling-air grille, both serv-
ing for good air circulation. For this pur-
pose, contact your professional
AGRIA workshop.
Exhaust System
l Constantly check exhaust system
(G/16) for plant trash and clean, if nec-
essary. Otherwise danger of fire.
l Check exhaust after every 200 oper-
ating hours for oil carbon and, if neces-
sary, clean or burn out.
For this purpose, contact your pro-
fessional AGRIA workshop.
Apart from adhering to operating instruc-
tions for power mowers, it is also impor-
tant to observe the following mainte-
nance instructions.
W
Warning: Only do mainte-
nance work with the engine
turned off and spark plug
connector removed. Always wear
safety gloves, when working near
mowing knives.
2-Stroke-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, Rotax 232
Change oil in oil bath air filter (F/10) af-
ter every 25 operating hours or at least
after 3 months (in case of heavy dust
occurence 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.
