To reduce the risk of accidents, do not
operate your power tool if it is not
properly assembled and in good
condition.
Switching On
Start the machine on a flat surface. Do
not tilt the machine when you switch on
the motor.
Do not switch on the machine in high
grass or with the cutting height set to the
lowest level.
Operate the machine only with the cover
closed.
During Operation
Make sure you always have good
balance and secure footing.
In case of imminent danger or in an
emergency, switch off the power tool
immediately, remove the fuse key and
the battery.
To reduce the risk of injury from thrown
objects, do not allow any other persons
within 15 meters of your own position.
To reduce the risk of damage to
property, also maintain this distance
from other objects (vehicles, windows).
Do not mow at outside temperatures
below +5°C.
Do not leave the machine outdoors in
the rain.
Take special care in slippery conditions
on slopes and uneven ground.
Do not operate your machine in the rain,
during thunderstorms or when there is a
risk of lightning strikes.
Never remove or bridge the switchgear
or safety devices installed in the
machine. Do not fix the switch lever in
position (e.g. by tying it).
Never operate your machine with the
handle folded down.
Do not switch on the machine if the
discharge chute is not covered by the
discharge flap or the grass box. Do not
leave the discharge chute open.
Do not mow extremely steep slopes. To
reduce the risk of injury, do not operate
your machine on slopes with a gradient
of more than 25°.
Mow parallel to the slope, never up or
down. Take particular care when
changing direction on slopes.
If a rotating metal cutting attachment
makes contact with a rock or other solid
object there is a risk of sparking which
may cause easily combustible material
to catch fire under certain
circumstances. Dry plants and scrub are
also easily combustible, especially in hot
and dry weather conditions. If there is a
risk of fire, do not use metal cutting
attachments near combustible
materials, dry plants or scrub. Always
contact your local forest authority for
information on a possible fire risk.
Watch out for obstacles: Tree stumps,
roots, especially when moving
backwards and pulling the machine –
risk of stumbling.
Work calmly and carefully – in daylight
conditions and only when visibility is
good. Stay alert so as not to endanger
others.
15 m (50 ft)
Keep hands and feet well
clear of rotating parts and
do not touch the rotating
cutting blade. To reduce
the risk of injury, always
maintain the distance
from the ejection chute
that is defined by the
handlebar.
Do not touch the cutting
blade while the motor is
running. Never open the
ejection chute shield or
remove the grass box
while the motor is run-
ning. There is otherwise a
risk of injury from the
rotating cutting blade.
Protect from rain – do not
immerse in fluids.
Inspect the work area:
Stones, pieces of metal
or other solid objects can
be thrown and cause per-
sonal injury or damage
the cutting blade and
property (e.g. parked
vehicles, windows).

RMA 510

To reduce the risk of accidents, take a
break in good time to avoid tiredness or
exhaustion.
Be particularly alert and cautious when
wearing hearing protection because
your ability to hear warnings (shouts,
alarms, etc.) is restricted.
The dust that occurs during operation
may be harmful to health. If dust levels
are very high, wear a suitable respirator.
Avoid contact with electrical cables or
wires – risk of electric shock.
If your power tool is subjected to
unusually high loads for which it was not
designed (e.g. heavy impact or a fall),
always check that it is in good condition
before continuing work – see also
"Before Starting Work". Make sure the
safety devices are working properly. Do
not continue operating your power tool if
it is damaged. In case of doubt, consult
your servicing dealer.
Check the cutting attachment at regular
short intervals during operation or
immediately if there is a noticeable
change in cutting behavior:
–Switch off the machine, allow
cutting blade to come to a complete
standstill, remove the fuse key and
the battery.
–Check condition and tightness, look
for cracks.
In the event of contact with foreign
matter, check the cutting blade for signs
of damage. Do not operate your power
tool with a damaged or bent blade shaft
or motor shaft.
If your machine begins to vibrate
unusually: Switch off the machine – risk
of injury. Inspect the whole machine,
particularly the cutting attachment, for
signs or damage or loose parts. Do not
use your machine until damaged parts
are replaced and loose parts properly
secured. STIHL recommends an
authorized STIHL servicing dealer.
If the cutting blade becomes obstructed,
or if there is a blockages in the discharge
chute or in the area of the cutting blade,
immediately switch off the motor, allow
the cutting attachment to come to a
complete standstill, remove the fuse key
and the battery. Rectify the cause of the
problem.
Do not overload your machine during
operation to a point where the motor
slows down. If motor speed begins to
slow, select a higher cutting height or
reduce the feed rate.
If the motor is thermally overloaded
during operation, it cuts out
automatically and must cool down
before it is restarted. Causes of
overload:
–Mowing overlong grass or at too low
a cutting height
–Mowing speed too high
–Cooling air slots dirty
Switching the machine on and off
frequently within a short period may
cause the motor to overheat.
Do not attach objects to the handlebar.
The machine must not be used for
transporting persons, particularly
children, or objects.
After Finishing Work
Before leaving the power tool
unattended: Switch off the motor,
remove the fuse key and battery.
Note that the cutting attachment
continues to run for a short period after
the power tool is switched off – flywheel
effect. The machine is equipped with a
coasting brake. The coasting brake
shortens the time required for the blade
to come to a standstill – see also
"Switching Off".
Allow power tool to cool down
completely.
Always clean dust and dirt off the power
tool – do not use any grease solvents for
this purpose.
Holding and Controlling the Power Tool
The machine is operated by one person
only – do not allow other persons,
especially children, or animals in the
work area.

RMA 510
English

Always hold the handle firmly with both
hands.
Operate the machine at walking pace
only – never run.
Maintenance and Repairs
Always remove the fuse key and battery
from the power tool before carrying out
any repairs or maintenance work. This
avoids the risk of the motor starting
unintentionally.
Service the machine regularly. Do not
attempt any maintenance or repair work
not described in the instruction manual.
Have all other work performed by a
servicing dealer.
STIHL recommends that you have
servicing and repair work carried out
exclusively by an authorized STIHL
servicing dealer. STIHL dealers are
regularly given the opportunity to attend
training courses and are supplied with
the necessary technical information.
Only use high-quality replacement parts
in order to avoid the risk of accidents
and damage to the unit. If you have any
questions in this respect, consult a
servicing dealer.
STIHL recommends the use of genuine
STIHL replacement parts. They are
specifically designed to match your
model and meet your performance
requirements.
Never attempt to modify your power tool
in any way since this will increase the
risk of personal injury.
Regularly check the electrical contacts
and ensure that the insulation of the
connecting cord and plug of the charger
is in good condition and shows no sign
of ageing (brittleness).
Electrical components, e.g. connecting
cord of charger, may only be repaired or
replaced by a qualified electrician.
Clean plastic surfaces with a cloth. Do
not use aggressive detergents. They
may damage the plastic.
Check tightness of mounting screws, on
the cutting attachment in particular, and
retighten if necessary.
Clean cooling air openings in motor
housing as necessary.
Keep the battery guides free from
foreign matter – clean as necessary.
Replace illegible or damaged warning
labels on the power tool.
Store the power tool in a dry, locked
location with the fuse key and battery
removed.
Vibrations
This power tool minimizes the vibrations
transmitted to the operator's hands.
However, the operator should seek
medical advice in the event of suspected
circulatory problems in the hands (e.g.
tingling sensation in the fingers).

Mowing
A beautiful and dense lawn is obtained
by frequent mowing.
The lawn should not be kept too short in
hot and dry weather because it will
otherwise be burned by the sun and
become unattractive.
A sharp blade produces a more
attractive finish than a dull one. Sharpen
the blade regularly – see also
"Sharpening the Cutting Blade".
Cuttings can be collected in the grass
box or ejected to the rear.
Mowing on Slopes
Your cordless lawn mower can be used
on gradients of up to 25°.
Cutting Performance
The cutting performance depends on
the type of grass and the height of cut
selected. Cutting performance is
increased by:
–Mowing frequently.
–Increasing the height of cut.
–Reducing mowing speed.
–Allowing lawn to dry before mowing.
Disposal
Do not throw cuttings in the garbage can
– they can be composted! Mulching
In the mulching mode, the grass
clippings are recirculated in the
airstream, re-cut several times into small
particles and then blown back onto the
lawn. The fine particles remain on the
lawn surface where they decompose
quickly and serve as a natural fertilizer.
Frequent mulching produces a beautiful,
dense lawn. One third of the grass
height should be cut in this process.
Mulch at least twice a week in spring and
at least once a week in summer/autumn.
Mulching Result
Prerequisites for good mulching results:
–Lawn should be dry
–Use properly sharpened blades
–Low mowing speed
–Vary mowing direction and overlap
the cuts
–Mow very high grass in gradual
stages
The housing can become clogged and
block the blade if the cutting height is too
low or the grass is wet.
Conversion for Mulching
The mulch insert must be fitted for
mulching.
