Oil type, summer (> 4ºC): SAE-30
(SAE 10W-30 can also be used. However, oil con-
sumption may increase somewhat if 10W-30 is
used. Therefore, check the oil level more regularly
if you use this type of oil).
Oil type, winter (< 4ºC): SAE 5W-30
(if this oil is not available, use SAE 10W-30).
Use oil without any additives.
Do not fill with too much oil. This can cause the
engine to overheat.
After filling up the oil, start the engine and idle for
30 seconds. Stop the engine. Wait for 30 seconds
and then check the oil level.
Check to see if there is any oil leakage. If neces-
sary, fill up the oil up to the "FULL" mark.
OIL FILTER – ENGINE (MF 880)
Replace the oil filter after every 100 hours of oper-
ation or once a season.
Before screwing the new filter, oil the filter gasket
with engine oil.
Screw the filter by hand, until the filter gasket
touches the filter attachment. Then tighten ½ to ¾
of a full turn (fig. 19).
Start the engine and idle to see if any leakage oc-
curs. Stop the engine. Check the oil level. If neces-
sary, fill up the oil up to the "FULL" mark.
AIR FILTER - ENGINE
Clean the foam pre-filter every 3 months or after
every 25 hours of operation, whichever comes
first.
Clean the paper filter insert once a year or after
every 100 hours of operation, whichever comes
first.
Note! Both filters should be cleaned more often if
the machine operates on dusty ground.
1. Remove the protective cover of the air filter (fig.
11-12).
2. Dismantle the paper filter insert and the foam
pre-filter. Make sure that no dirt gets into the car-
burettor. Clean the air filter housing.
3a. MF 880
Wash the pre-filter in liquid detergent and water.
Squeeze dry. Pour a little oil on the filter and
squeeze in the oil.

3b. MF 860
Replace the pre-filter once a year or after every 25
hours of operation, whichever comes first.
4. Clean the paper filter insert as follows: Knock it
lightly against a flat surface. If the filter is very
dirty, change it.
5. Assemble in the reverse order.
Petroleum-based solvents such as kerosene may
not be used for cleaning the paper filter insert.
These solvents can destroy the filter.
Do not use compressed air for cleaning the paper
filter insert. The paper filter insert must not be
oiled.
SPARK PLUG
Only use a Briggs & Stratton sparking tester to
check the spark in the sparking plug (fig. 13).
Clean the spark plug after every 100 hours of oper-
ation or once a season. For replacing a spark plug,
a spark plug sleeve A and a torsion pin B are pro-
vided in the accessories bag.
The engine manufacturer recommends:
Champion RC12YC
Correct spark gap: 0.75 mm.
COOLING AIR INTAKE - ENGINE
The engine is air-cooled. A blocked cooling sys-
tem can damage the engine. The engine should be
cleaned at least once a year or every 100 hours of
operation.
Remove the fan casing. Clean the cooling fins on
the cylinder, the fan and the rotating protective
grille. Clean more frequently if mowing dry grass.
BATTERY
The battery is a valve-regulated battery with 12 V
nominal voltage. The battery is completely main-
tenance free. You don't have to check or top up the
electrolyte level.
On delivery, the battery is in the accessories box.
The battery must be fully charged be-
fore being used for the first time. The
battery should always be stored fully
charged. If the battery is stored while
totally flat it could sustain permanent
damage.
If the machine is not going to be used for an ex-
