Safety Precautions and

Working Techniques

Because this lawn mower

is a high-speed, fast-cut

ting power tool and is

battery-powered, special

safety precautions must

be observed to reduce

the risk of personal injury.

It is important that you

read, fully understand

and observe the following

safety precautions and

warnings. Read the

instruction manual and

the safety precautions

periodically. Careless or

improper use may cause

serious or fatal injury.

RMA 510

English

WARNING

Use your lawn mower only for mowing

grass. Do not use it for other purposes.

Misuse may result in personal injury or

property damage, including damage to

the mower or its blade.

WARNING

Minors should never be allowed to use

this power tool. Bystanders, especially

children, and animals should not be

allowed in the area where it is in use.

Accidents can occur if the operator is not

alert to the presence of children.

Children are often attracted to the

machine and mowing activities. Never

assume that children will remain where

you last saw them. Keep children under

the watchful eye of a responsible adult

other than the operator. Use extra care

when approaching blind corners,

shrubs, trees or other objects that may

block your view of a child.

WARNING

To reduce the risk of injury to bystanders

and damage to property, never let your

lawn mower run unattended. When it is

not in use (e.g. during a work break),

shut it off and make sure that

unauthorized persons do not use it. To

do this, remove the fuse key and battery

from the power tool.

Most of these safety precautions and

warnings apply to the use of all STIHL

lawn mowers. Different models may

have different parts and controls. See

the appropriate section of your

instruction manual for a description of

the controls and the function of the parts

of your model.

Always remove fuse key and battery

before inspecting, cleaning,

transporting, storing or carrying out any

work on the mower. This avoids the risk

of the motor starting unintentionally.

Use only original STIHL replacement

parts, including the cutting blade. They

are specifically designed to match your

model and meet your performance

requirements. Use of non

STIHL parts

may reduce the operational efficiency of

the mower or may cause serious or fatal

injury.

Safe use of a lawn mower involves

1. the operator

2. the power tool

3. the use of the power tool.

RMA 510

English

WARNING

Release the switch lever and wait for the

cutting blade to come to a complete stop

before removing the grass bag or

wheeling the mower over surfaces other

than grass. Stay behind the handle

when the motor of the mower is running.

WARNING

Do not overreach. Keep proper footing

and balance at all times. Special care

must be taken in slippery conditions and

in difficult, overgrown terrain. Watch for

hidden obstacles such as tree stumps,

roots and ditches to avoid stumbling.

Tall grass can hide obstacles and

debris. Do not mow near drop offs,

ditches or embankments. You could lose

your footing and balance. Be extremely

cautious when working on slopes or

uneven ground. Slopes are a major

factor related to slip and fall accidents,

which in turn can result in severe injury.

Do not mow extremely steep slopes. To

reduce the risk of injury, do not operate

your machine on slopes with a grade of

more than 25%. If you feel uneasy on a

slope, do not mow it.

WARNING

Do not pull the mower backwards unless

absolutely necessary. Always look down

and behind before and while mowing

backwards.

Working Conditions

Operate your mower only under good

visibility and daylight conditions. Work

carefully.

WARNING

If the vegetation being cut or the

surrounding ground is coated with a

chemical substance (such as an active

pesticide or herbicide), read and follow

the instructions and warnings that

accompanied the substance involved.

WARNING

Inhalation of certain dusts, especially

organic dusts such as mold or pollen,

can cause susceptible persons to have

an allergic or asthmatic reaction.

Substantial or repeated inhalation of

dust and other airborne contaminants, in

particular those with a smaller particle

size, may cause respiratory or other

illnesses. Control dust at the source

where possible. Use good work

practices, such as operating the mower

so that the wind or operating process

directs any dust raised by the power tool

away from the operator. Follow the

recommendations of

EPA/OSHA/NIOSH and occupational

and trade associations with respect to

dust ("particulate matter"). When the

inhalation of dust cannot be

substantially controlled, i.e., kept at or

near the ambient (background) level, the

operator and any bystanders should

wear a respirator approved by

NIOSH/MSHA for the type of dust

encountered.

Operating Instructions

Start the mower on a flat surface. Do not

tilt the mower when you switch on the

the motor immediately by releasing the

switch lever and remove the fuse key

and battery.

To reduce the risk of cut

injuries, never put hands

or feet near or under the

machine or near the ejec

tion chute. Never touch a

moving cutting blade with

your hand or any other

part of your body. To

reduce the risk of injury,

never attempt to clear

clippings or debris from

cutting blade, deck or

ejection chute without

first switching off motor

and removing fuse key

and battery.

Mow parallel to the slope,

never up or down. Take

particular care when

changing direction on

slopes.

Keep hands and feet

away from cutting blade.

RMA 510

English

WARNING

The cutting blade continues to rotate for

a short period after the switch lever is

released. This is known as the flywheel

effect.

WARNING

The rotating cutting blade may throw

foreign objects directly or by ricochet.

Keep bystanders, especially children,

and animals away from the work area.

To reduce the risk of injury ensure that

bystanders are at least 50 feet (15 m)

away. To reduce the risk of damage to

property, also maintain this distance

from such objects as vehicles or

windows.

Switch off the motor immediately by

releasing the switch lever if you are

approached.

WARNING

To reduce the risk of personal injury:

Operate the mower at walking pace only

– never run.

Do not use the mower for transporting

persons, particularly children, or objects.

Do not attach objects to the handle.

WARNING

During cutting, check the tightness and

the condition of the cutting blade at

regular short intervals with the motor

and blade stopped and the fuse key and

battery removed. If the behavior of the

blade changes during use, switch off the

motor immediately, wait until the cutting

blade stops, remove the fuse key and

battery and check the screw securing

the blade for tightness and the blade for

cracks, wear and damage. Never

examine the cutting blade while the

motor is running. To avoid the risk of

injury from the rotating cutting blade,

never open the rear discharge cover or

remove the grass bag while the motor is

running.

If the machine should start to vibrate

abnormally, stop the motor, remove the

fuse key and battery and check for the

cause immediately. Vibration is

generally a warning of trouble. Do not re-

start the motor until the cause of the

abnormal vibration is identified and

resolved.

WARNING

If the cutting blade becomes obstructed,

or if there is a blockage in the rear or

side discharge chutes or in the area of

the cutting blade, always switch off the

motor, remove the fuse key and battery

and make sure the cutting blade has

stopped before cleaning.

In the event of contact with foreign

matter, check the cutting blade for signs

of damage. Do not operate your mower

with a damaged or bent blade shaft or

2. Remove the fuse key and battery

before picking up or carrying the

mower and before making any

adjustments, changing accessories

or storing. Such preventive safety

measures reduce the risk of starting

the mower accidentally.

3. Recharge only with the charger

specified by STIHL. A charger that

is suitable for one type of battery

may create a risk of fire when used

with another battery.

4. Use the mower only with the

specifically designated batteries.

Use of any other battery may create

a risk of fire or explosion and

personal injury or property damage.

5. When the battery is not in use, keep

it awa y from o ther me tal obj ects, l ike

paper clips, coins, keys, nails or

other small metal objects that can

make a connection from one

terminal to another. Do not store it in

a metal container. Shorting the

battery terminals together may

cause burns or a fire or explosion.

6. Under abusive conditions, liquid

may be ejected from the battery;

avoid contact. If contact accidentally

occurs, flush with water. If liquid

contacts eyes, additionally seek

medical help. Liquid ejected from

the battery may cause irritation,

chemical burns or respiratory illness

from inhalation.

7. Do not use a battery or mower that

is damaged or modified. Damaged

or modified batteries may exhibit

unpredictable behavior resulting in

fire, explosion and risk of injury or

property damage.

8. Do not expose a battery or the

mower to fire or excessive

temperature. Exposure to fire or

temperature above 212° F (100° C)

may cause fire and explosion.

9. Follow all charging instructions and

do not charge the battery outside of

the ambient temperature range

specified. Charging improperly or

outside the specified range may

Mowing

Frequent mowing contributes to a

beautiful and dense lawn.

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 mulched, collected in

the grass bag or ejected from the side

discharge chute.

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 contributes to a

beautiful, dense lawn. One third of the

grass height should be cut in this

process.

It is advisable to mulch at least twice a

week in spring and at least once a week

in summer/autumn.

Mulching Result

Prerequisites for good mulching results:

– Only cut dry grass

– Use properly sharpened blades

– Reduce mowing speed

– Vary mowing direction and overlap

the cuts

– Mow very high grass in gradual

stages

The underside of the mower deck can

become clogged and block the blade if

the cutting height is too low or the grass

is wet.
