6.1 General Remarks 
on the Care of Lawns
At the beginning of the grasscutting season and with newly 
laid lawns, we recommend you 
select a relatively high cutting 
height (e.g. 45 mm) then gradually 
decrease the cutting height over 
time. To maintain a well kept lawn 
you should set the cutting height 
to approximately 20 mm.
If possible, mow your lawn once 
a week. When you mow your lawn 
frequently the short roots of the 
grass grow making your lawn 
more resistant. Always mow your 
lawn when it is relatively dry. 
To obtain a clean cut guide the 
Accu Cordless Motor Mower in 
lanes as straight as possible at 
a walking pace. 
Ensure that the lanes overlap 
by a few centimetres so that no 
uncut strips are left behind.
Cut the lawn for the first time in 
spring when the grass begins to 
grow and the lawn can be walked 
on. If the grass has grown too 
long first cut it length-wise with 
a high cutting height setting 
(approx. 45 mm) and then cut 
at right angles with the desired 
lower cutting height setting (e.g. 
25 mm).
The area of lawn you can mow 
with one charged accu depends 
on the height and thickness of 
the lawn, i.e. the taller and thicker 
the lawn, the smaller the area of 
lawn you can mow with one fully 
charged Accu.
6.2 Mowing 
Tip: Only cut with a sharp cutting cylinder so that the grass 
is not bruised and turn yellow.
For a clean cut guide the Cordless Motor Mower at an appropriate speed in lanes as straight 
as possible.
Note: The Cordless Motor Mower 
can be operated with the Accu 
or without as a hand mower.
Warning: The revolving cutting 
cylinder can cause injuries. 
Always maintain the distance 
between the cutting cylinder 
and user suggested by the 
guide handle.
When working on inclines 
always stand diagonally to the 
incline in a sturdy, safe stance.
To prevent tripping, take particular care when moving backwards and when pulling the 
Cordless Motor Mower.
For information on how to set 
the cutting height see section 
“Setting the Cutting Height”.
Blockage Protection
If the mower is blocked by a foreign body or if the motor is overloaded, the motor is automatically 
switched off by the blockage protection. Remove the key from the 
socket. Remove the foreign body 
or the cause for the overload and 
after a few seconds restart the 
mower. 
If the motor switches off although 
there are no foreign bodies in the 
cutting tool it is possible that the 
cutting height you have selected 
is too low. Select a higher cutting 
height, e.g. 45 mm and then 
select a lower cutting height for 
the second cut.
Circuit Breaker
If the Cordless Motor Mower is 
overloaded over a longer period of 
time the motor may become hot. 
To protect the motor from overheating the circuit breaker switches the motor off.You can switch 
the mower on again after approximately 5-10 minutes.
Automatic Cut-Off 
(discharge protection)
The mower switches off automatically as soon as the capacity 
of the Accu has been exhausted 
(discharge protection). We recommend recharging the battery 
straight away.
Key
To prevent switching on the Motor 
Mower unintentionally, remove 
the key 
Q
from the socket.
6.3 Mowing with the Grass 
Catcher (optional) (Fig. F)
A
Only attach the grass
catcher when the motor 
is switched off and the cutting 
tool has stopped moving.
Using the GARDENA grass 
catcher saves you having to rake 
together the grass cuttings.
To attach the grass catcher:
1. Hook the grass catcher holders
G
over the hooks Hof the 
Cordless Motor Mower and
2. Hook the carrying chain onto
the lower part of the guiding 
handle. 
Note: The height of the grass 
catcher can be adjusted using 
the latch-in hook on the chain.
For the best grass-catching 
results, push your mower at a 
walking pace.
6. Information Concerning Correct Mowing
7.1 Maintenance
Maintenance includes all jobs 
which keep your Accu Cordless 
Motor Mower in perfect working 
order. By regularly checking the 
unit (firm seating of screw connections, cracks, damage) and 
replacing defective or worn parts 
you can prevent accidents and 
failure.
Repairs may only be carried 
out by GARDENA service 
centres or dealers authorised 
by GARDENA.
A
Before cleaning and set-
ting the Motor Mower, 
switch off the motor and 
remove the key Qto prevent 
starting the motor unintentionally.
7.2 The Accu (Fig. E/G) 
Charging the Accu
A
Note: Only charge the
Accu with the charger 
supplied! Using other charging 
units could lead to damage and 
injury. Using a charger other 
than the GARDENA charger 
supplied releases GARDENA 
from all liability and warranty 
claims.
A
Warning! The mower 
cannot be started as long 
as the charger is plugged in!
We recommend charging the 
Accu immediately after using 
your mower using the supplied 
charger 
J
for 24 hours.
Important ! If you do not use 
the Accu for a longer period of 
time it will get its full efficiency 
after several charging cycles.
If the Accu is completely flat, 
e.g. due to too long storage 
without any recharge, it will 
get its full efficiency again after 
several charging cycles.
A
Attention! Never charge
the Accu after having 
been heated up by operation 
or sun. Let cool down first.
Never expose the Accu to 
direct sunlight while charging.
Never charge the Accu anywhere near acids and easily 
inflammable materials. 
Danger of fire!
Note: Do not wait until the Accu is
completely flat before recharging. 
Charge the Accu in a dry place 
as follows (Fig. G):
1. Open the accu cover 
N
.
2. Remove the key Qfrom the 
socket.
3. Plug the plug Kof the charger 
into the charging socket 
L
.
4. Then plug the mains plug 
M
of the charger into the mains 
socket.
5. To resume mowing after charging the accu, replace the key in 
the socket and close the accu 
cover.
Important :
.
Protect the charging socket 
against dirt and moisture.
.
If the Accu capacity is so 
low that the Cordless Motor 
Mower switches off automatically (discharge protection) 
then the charging time is 
24 hours.
Charging the Accu directly with 
the GARDENA Charging Cable 
(Art. No. 4040-00.900.01 – 
available from GARDENA 
Service)
1. Take off the Accu (see 
“Changing the Accu”).
2. Put the socket of the charging 
cable into the plug of charger
K
.
3. Connect the plus pole (+) of 
the battery with the red clip 
and the minus pole (–) with 
the black clip.
4. Then plug the mains plug of 
the charger into the mains 
socket.
5. Loosen all connections in 
reverse after charging.
6. Insert the Accu (see 
“Changing the Accu”).
Care 
Important ! If you do not use the
Accu for longer periods of time, 
it must be re-charged every 
6 months to maintain its full efficiency.
Changing the Accu (Fig. E) 
If the Accu capacity is completely 
exhausted or if the Accu can no 
longer be recharged it must be 
exchanged. New Accus are available from your GARDENA dealer 
or directly from GARDENA Service, Art. No. 4040-00.600.20.
Exchange the Accu as follows:
1. Switch off the Motor Mower.
2. Open the accu cover 
N
.
3. Remove the key from the 
socket to prevent starting the 
Motor Mower unintentionally.
4. Remove the Accu. Pay attention to the position of the Accu 
in the housing.
5. Pull the receptacle for the tabs
O
from the tabs P.
6. Insert the new Accu in the 
holder in the correct position
as shown in Fig. E1.
7. Important ! Pay atten-
A tion to the + / – markings 
and the colour markings of 
the receptacle for the tabs.
Push the red tab receptacle 
on the tab labelled with a plus 
sign (+) and the black tab 
receptacle on the tab labelled 
with a minus sign (–).
8. Please dispose of the Accu 
according to the information in 
the chapter entitled “Disposing 
of and Recycling Accus”.
7.3 The Cordless Motor Mower
Cleaning
A
To avoid injury to persons 
and material damage: 
Never clean your Cordless 
Motor Mower with running 
water, in particular with water 
under high pressure.
After using the mower clean with 
a moist cloth. Spray the cutting 
cylinder and lower blade with an 
oil of low viscosity (e.g. spray oil).

This will prevent the mower 
switching off automatically, 
and could cause fatal injury.
Attention! Cutting cylinder continue to run for a few seconds 
after the motor is switched off.
When working with the Cordless Motor Mower the Accu 
heats up; this is normal and 
does not affect its performance.
