Before Mowing - Scheppach RM420 Originalbetriebsanleitung

Never mix oil with petrol. Buy fuel in amounts
which can be used within 30 days in order to guar-
antee 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.
Stop engine:
• To turn off the engine, 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.

Before mowing

Important information
• Make sure that you are properly dressed when
mowing. Wear sturdy, non-slip footwear; do not
wear sandals or tennis shoes.
• Inspect the blade. A blade that is bent or damaged
in any other way must be immediately exchanged
for a genuine replacement blade.
• Do not fill the fuel tank indoors, but rather out in
the open. Use a filling funnel and a measuring jug.
Wipe off any spilled petrol.

• Read and follow in the instructions in the operating
manual as well as the information regarding
the engine and accessory equipment. Store
the manual in a place where it can be readily
accessed by other users of the machine.
• Exhaust gas is dangerous. Only start the engine
out in the open.
• Make sure that all the guards are fitted and that
they are in good working order.
• The machine should only be operated by persons
who are well informed with the way it works, and
who are in reasonably good physical condition.
• It can be dangerous to mow the grass when it is
wet. Try to ensure that you only mow the grass
when it is dry.
• Advise children and others to keep well away from
the lawn mower.
• Never mow the grass in poor visibility.
• Remove all loose objects from the lawn before you
start mowing the grass.
Tips for proper mowing
m CAUTION!
the catch bag has been detached (to be emptied)
and the engine is still running. The rotating blade
can cause serious injuries!
Always carefully fasten the chute flap and grass
basket. Switch off the engine before emptying the
grass basket.
Always ensure that a safe distance (provided by the
length of the long handles) is maintained between
the user and the mower housing. Be especially
careful when mowing and changing direction on
slopes and inclines. Maintain a solid footing and wear
sturdy, non-slip footwear and long trousers. Always
mow along the incline (not up and down).
For safety reasons, the lawn mower may not be used
to mow inclines whose gradient exceeds 15 degrees.
Use special caution when backing up and pulling the
lawn mower. Tripping hazard!
Mowing
Only use a sharp blade that is in good condition.
This will prevent the grass blades from fraying and
the lawn from turning yellow. Try to mow in straight
lines for a nice, clean look. Insodoing, the mowing
swaths should always overlap each other by a few
centimeters in order to avoid bare strips.
Keep the underside of the mower housing clean and
remove grass build-up. Deposits not only make it
more difficult to start the mower; they decrease the
quality of the cut and make it harder for the machine
to bag the grass. Always mow along inclines (not up
and down). Slightly turning the front wheels up the
hill while mowing will prevent the mower from sliding
out of the straight line. Select the cutting height
according to the length of the grass.
