Operation - Scheppach MS139-42 Originalbetriebsanleitung

m CAUTION!
Adjust the cutting height only when the engine is
switched off and the plug boot has been pulled.
• Before you begin to mow, check to ensure that the
blade is not blunt and that none of the fasteners
are damaged.
• To prevent any imbalance, replace blunt and/or
damaged blades as a set only (if applicable). To
carry out this check, first switch off the engine and
pull the spark plug boot.
• The cutting height is centrally adjusted with the
cutting height adjustor lever (Fig.13/ Item 14). 5
different cutting heights can be selected.
• Pull the adjustor lever out and select the desired
cutting height. The lever snaps into the desired
position. (Fig. 13)

8. Operation

m CAUTION!
The engine does not come with oil in it. Therefore,
ensure that you add oil before starting it up. Use
normal, multigrade oil (SAE 30 / 10W30). The oil
level in the engine must be checked each time before
mowing.
You will also need to fill in petrol, as this is also not
supplied upon delivery.
• In order to avoid any unintentional start-ups of the
lawn mower, it comes equipped with an engine
brake (Fig. 1/ Item 3) which must be pulled back
before the engine can be started. When the engine
control lever is released it must return to its initial
position, at which point the engine automatically
switches off.
• Press the engine brake lever (3) together and give
the starter cord (17) a vigorous pull. (Fig. 14)
Attention:
When you pull the starting rope the cutting blade
rotates even when dissolved motor brake lever.
Make sure that there are no body parts in danger
zone of cutting blade.
• When the engine is running, press the drive lever
(2) to the handle (1) in order to engage drive on the
mower.
• Before you start mowing, you should run through
this operation several times in order to ensure that
the machine is working properly.
m WARNING
Whenever you need to perform any kind of ad-
justment and/or repair work on your lawn mower,
wait until the blade has come to a complete stop.
Always switch off the engine before carrying out
any adjustments, maintenance or repairs.
m Note!
Using the drive:
• Engine brake (3): Use the lever to stop the engine.
When you release the lever the engine and the bla-
de stop automatically.
• To mow, hold the drive lever (2) in the working
position. Before you start to mow, check the start/
stop lever several times to be sure that it is working
properly. Ensure that the tension cable can be
smoothly operated (i.e. is not catching or kinking in
any way).
• Drive lever (2):
If you press this the clutch for the drive will be
closed and the lawnmower will start to move with
the motor running. Release the drive lever in good
time to stop the moving lawnmower. Practice
starting and stopping before you use the mower for
the first time until you are familiar with controlling
the mower.
Caution: The blade begins to rotate as soon as the
engine is started.
Important: Before you start the engine, move the
motor brake several times to be sure that the stop
cable is properly working.
Note: The engine is factory set to a speed that is
optimal for cutting and blowing grass into the basket
and is designed to provide many years of use.
• Check the oil level.
Open the fuel tank cap and fill the petrol tank (6)
up to the lower point of the tank inlet with about 1
litres of petrol. Use a funnel and a measuring con-
tainer for filling. Do not overfill the tank. Use fresh,
clean unleaded fuel.
Never mix oil with petrol. Buy fuel in amounts
which can be used within 30 days in order to gua-
rantee its freshness.
Note: Use only unleaded gasoline.
m WARNING
Only use a safety petrol can. Do not smoke when
refueling. Remove any oil or petrol residues. Switch
off the engine before refueling and allow the engine
to cool down for a few minutes.
Start engine (Fig. 14)
• Ensure that the ignition cable is connected to the
spark plug.
• Stand behind the mower. One hand squeezes the
engine brake lever (3) to the handle, the other pulls
the pull start.
• Start the engine using the reversing starter (17).
To do this pull the handle approx. 10 – 15 cm (until
you feel a resistance) and then start the engine
with a sharp pull. If the engine does not start, pull
the handle again.
• Due to protective coating on the engine, a small
amount of smoke may be present during the initial
use of the product and should be considered
normal.
Note: Easier starting in colder temperatures by
pressing the primer (Fig. 15/ pos.8). Use only by a
cold engine!
m CAUTION!
• Never allow the starter cord to snap back.
• Note: In cold weather, it may be necessary to
repeat the starting process several times.
Motor abschalten:
• To turn off the engine, release the drive lever (2), then
the engine brake lever (3) and wait for the blades to
stop.
• Pull the spark plug boot from the spark plug (10) boot in
order to prevent the engine from restarting.
• Before you start the engine again, check the cord for
the engine brake. Check that the cord is correctly fitted.
If the cord is kinked or damaged, it should be replaced.
