ation or at least once a season) if the engine has to
operate under demanding conditions or if the am-
bient temperature is high.
The engine oil may be very hot if it is
drained off directly after the engine is
shut off. So allow the engine to cool a
few minutes before draining the oil.
1. Oil drain pipe (metal):
Unscrew the oil drain plug at the end of the pipe.
Collect the oil in a collection vessel. Then take
the oil to a recycling station. Do not allow oil to
get on the V-belts.
2. Screw in the oil drain plug. Make sure that the
fibre gasket and the O-ring inside the plug are not
damaged and that they are in the correct place.
3. Remove the dipstick and fill up with new oil.
Oil capacity: 1.4 l
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, MF 890 PRO)
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. 20).
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.

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. 14).
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.
