Maintenance And Cleaning - Scheppach MS150-42 Originalbetriebsanleitung

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 guar-
antee the safety level and performance of the ma-
chine.
• Make sure that all nuts, bolts and screws are tight-
ened securely and that the machine is in safe work-
ing condition.
• Routinely check the grass basket for signs of wear
and impaired functionality.
Regularly clean the grass box with water and let it
dry thoroughly.
• For your own safety, replace worn or damaged
parts without delay.
• If the fuel tank should require emptying this should
only be done in the open air using a petrol suction
pump (available from DIY shops).
m WARNING
Never work on or touch conducting parts on the ig-
nition unit with the engine running. Always pull the
spark plug boot from the spark plug before starting
any work of care or maintenance. Never perform any
work on the machine while it is running. Any work not
described in these Operating Instructions must be
performed by an authorized service workshop only.
Cleaning
The lawn mower should be thoroughly cleaned after
every use, especially the underneath and the blade
mount.
Clean the device with water as follows. (Fig. 23)
• Place the hose connection piece onto the water
connection (w) of the mower and open the tap.
• Start the mower and switch off again after about 30
seconds. The rotating blade bar throws the water
onto the bottom of the mower and thus cleans it.

• Turn off the tap and remove the hose connection .
• Clean the top with a cloth (do not use any sharp
objects).
m Note! Before you tip the lawn mower onto its side,
completely empty the fuel tank using a petrol suc-
tion pump. The lawn mower must never be tilted by
more than 90 degrees. Dirt and grass is easiest to
remove immediately after you have finished mowing
the grass.
Dried on grass and dirt can result in poorer mowing
performance. Check that the grass chute is free of
any residual grass. Remove any such residue. Never
clean the lawn mower with a water jet or high-pres-
sure cleaner. The engine must remain dry. Do not use
aggressive cleaning agents such as cold cleaner or
petroleum ether.
Wheel axles and wheel hubs
• These should be lightly greased once a season.
Blade
For safety reasons you should only ever have your
blade sharpened, balanced and mounted by an au-
thorized service workshop. For optimum results it is
recommended that the blade should be inspected
once a year.
Changing the blade (Fig. 17)
Only ever use original spare parts when having the
blade replaced.
Wear gloves when replacing the blade in order to pre-
vent injury.
Never have any other blade fitted.
• Empty the fuel tank before removing the blade
• To replace the blade, undo the screw.
• Reinstall as illustrated in Fig. 17. Tighten the screw
properly. Tightening torque 45 Nm. When replacing
the blade, the blade screw should also be replaced.
Damaged blades
Should the blade, in spite of all precautions, come
into contact with an obstruction, shut down the en-
gine immediately and pull the spark plug boot. Tip
the lawn mower onto its side and check the blade for
damage. Damaged or bent blades must be replaced.
Never attempt to bend a bent blade back to straight
again. Never mow the lawn with a bent or heavily
worn blade as this will cause vibrations and can lead
to further damage to the lawn mower.
m CAUTION! There is a risk of injury if you work with
a damaged blade.
Resharpening the blade
The blades can be resharpened with a metal file. In
order to avoid imbalance, the blade should be re-
sharpened by an authorized service workshop
