Maintenance And Cleaning - Scheppach RM420 Originalbetriebsanleitung

If the lawn has grown quite a bit, mow over it several
times so that no more than 4 cm of grass are cut
at one time. Switch off the engine before doing
any checks on the blade. Keep in mind that the
blade continues to rotate for a few seconds after
the engine has been switched off. Never attempt to
manually stop the blade.
Regularly check to see if the blade is securely
attached, is in good condition and is sharp. If
the contrary is the case, sharpen the blade or
replace it. In the event that the blade strikes an
object,immediately switch off the lawn mower and
wait for the blade to come to a complete stop. Then
inspect the condition of the blade and the blade
mount. Replace any parts that are damaged.
Tips for proper mowing:
• Pay attention to ensure that you do not run into
or over anything that could damage the mower.
The lawn mower could be damaged and/or the
machine could inflict bodily injury.
• A hot engine, exhaust or drive unit can burn the
skin if touched. Thus, do not touch these parts
unless the mower has been switched off for a
while and you know that they have cooled down!
• Use extra caution when mowing on inclines and
steep grades.
• Insufficient daylight or even a sufficient level of
artificial light is one reason not to mow.
• Check the mower, the blade and other parts if
they have struck a foreign object or if the machine
vibrates more than usual.
• Do not make any adjustments or repairs until the
engine has been switched off. Pull the plug boot.
• Pay special attention if you are mowing directly
next to a street or are close by one (traffic). Always
keep the grass chute pointed away from the street.
• Avoid mowing in places where the wheels have
trouble gripping or mowing is unsafe in any other
way. Before you back up, ensure that nobody is
standing behind you (especially little children, who
are more difficult to see).
• When mowing over thick, high grass, select the
highest cutting level and mow at a slower speed.
Before you remove any grass or blockages of any
kind, switch off the engine and pull the plug boot.
• Never remove any safety-related parts.
• Never fill the engine with petrol when it is hot or is
running.
Emptying the grass basket
The debris bag (16) is equipped with a filling level
indicator (Fig. 16). This will be opened by the air
current produced by the mower. If the flap falls dur-
ing mowing, the debris bag (16) is full and should
be emptied. To ensure that the filling level indicator
works properly, the holes under the flap must be kept
clean and permeable.
As soon as grass clippings start to trail the lawn
mower, it is time to empty the grass basket.

m WARNING
Before taking off the grass basket, switch off the
engine and wait until the blade has come to a
stop.
To take off the grass basket (16), use one hand to
lift up the chute flap (15) and the other to grab onto
the basket handle (Fig.16). Remove the basket. For
safety reasons, the chute flap (15) automatically falls
down after removing the grass basket and closes off
the rear chute opening.
If any grass remains in the opening, it will be easier
to restart the engine if you pull the mower back
approx. 1 meter. Do not use your hands or feet to
remove clippings in or on the mower housing, but
instead use suitable tools such as a brush or a hand
broom.
In order to ensure that the majority of grass clippings
are picked up, the inside of both the grass basket
(16) and especially the air grill must be cleaned
after each use. Reattach the grass basket (16) only
when the engine is switched off and the blade is
stopped. Using one hand, lift up the chute flap (15),
while grabbing onto the basket handle with the other.
Hang in the basket from the top. Fig. 9
After mowing
• Allow the engine to cool before you put the lawn
mower in an enclosed area.
Remove grass, foliage, grease and oil before
storing the mower. Do not place any objects on top
of the mower.
• Check all the screws and nuts once more before
you start to use the lawn mower again. Tighten
any loose screws.
• Also be sure to empty the grass basket (16).
• Pull the spark plug boot to prevent unauthorized
use.
• Ensure that you do not park the mower next to
any source of danger. Petrol fumes can lead to
explosions.
• Only original parts or parts approved by the
manufacturer may be used for repairs (see
address on the warranty certificate).
• If the lawn mower is not going to be used for an
extended period, empty the petrol tank using a
petrol suction pump.
• Oil and maintain the machine.

9. Maintenance and cleaning

• Regular, careful maintenance is required to
guarantee the safety level and performance of the
machine.
• Make sure that all nuts, bolts and screws are
tightened securely and that the machine is in safe
working condition.
