The engine oil may be very warm if it is
drained off directly after the engine is
shut off. Therefore, 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.
Let the oil run out into a collection vessel. Then
take the oil to a recycling station. Do not allow
oil to get on the V-belts.
2. Screw up 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:
Senator, President – 1.4 l
Royal – 1.9 l (including oil filter)
Pro16, Pro18, Pro20 - 1.7 l (including oil filter)
Oil type summertime (> 4º C): 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 (< 4º C): SAE 5W-30
(if this oil is not available, use SAE 10W-30).
Use oil without any additives.
Do not fill too much oil as this can result in over-
heating the engine.
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 (Royal - Pro16
- Pro18 - Pro20)
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. 17 - 18).
Start the engine and idle to see if any leakage oc-
curs. Switch off the engine, check the oil level. If
necessary, 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! The filters should be cleaned more often if
the machine operates on dusty ground.
1. Loosen the wing nut under the fuel tank and
move it backwards (fig. 16). Also loosen the bat-
tery to make it easier to get at the air filter (applies
to Pro16-Pro18-Pro20).
2. Remove the protective cover of the air filter (fig.
19 - 21).
3. 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.
4. Wash the pre-filter in liquid detergent and water.
Squeeze dry. Pour a little oil on the filter and
squeeze in the oil.
5. Clean the paper filter insert as follows: Knock it
lightly against a flat surface. If the filter is very
dirty, change it.
6. Assemble in the reverse order.
Petroleum-based solvents such as kerosene must
not be used for cleaning the paper filter insert as
these can destroy the filter.
Do not use compressed air for cleaning the paper
filter insert. The paper filter insert must not be
oiled.
AIR FILTER - CATALYTIC CONVERT-
ER (Pro18 - Pro20)
Clean the catalytic converter’s air filter every 3
months or after every 25 hours of operation,
whichever comes first.
1. Remove the cover by pressing in the locking
mechanism with a screwdriver, etc. (fig. 22).
2. Remove the foam filter and wash it in liquid de-
tergent and water. Squeeze dry. Pour a little oil on
the filter and squeeze in the oil.
3. Replace the filter and snap the lock into place.
SPARKING PLUG
Only use a Briggs & Stratton sparking tester to
