7.3 Care
A
Warning : Always discon-
nect the mains plug be-
fore working on the scarifier !
Clean the wheels of the scarifier
immediately after you have used
it to remove grass etc.
Important ! Do not rinse the
scarifier with water.
Also remove grass etc. from the
aerator cylinder.
Important : To prevent damag-
ing the scarifier, do not use
hard or sharp objects to re-
move the grass.
Note : Mixed with cooling air that
was taken in, the air inlets may
collect dirt. Therefore remove all
dirt from the air inlets before put-
ting into operation.
7.4 Storage
Always store the scarifier in a
closed room.
A
Checks before each
Operation
Inspect the unit before each
use. Do not use the Electric
Lawn Scarifier if safety devices
(starting lever; safety cover)
are damaged or worn. Never
operate the unit with the safety
devices by-passed or missing.
Note : Ensure that all nuts, bolts
and screws are tight and that
the scarifier is in good working
order. For safety reasons, allow
all worn out and damaged parts
to be exchanged by GARDENA
Service or authorised specialist
dealers.
Inspect the area to be aerated
before beginning work.
Remove any foreign objects
(e.g. stones) from the area.
Check the working area for
foreign objects (e.g. stones,
branches) during work.
A
Proper Use /
Responsibility
This Electric Lawn Scarifier
can cause serious injuries !
You are responsible for the
safety of the working area.
Only use the Electric Lawn
Scarifier for the purposes
specified in these instructions.
Only work when visibility is
good.
Familiarise yourself with the
surroundings of your work-
ing area. Check for possible
risks which might be not
audible due to the noise of
the machine.
Wear sturdy shoes and long
trousers to protect your legs.
Keep fingers and feet away
from the aerator cylinder.
Danger of injury !
Make sure that there are no
other people (especially chil-
dren) or animals anywhere
near the working area.
Always push the scarifier at
a walking pace.
Ensure that you have a secure
foothold when working. The
cable should always be kept
away from the aerating area.
Attention! Take extra care when
walking backwards. You may
stumble !
If, in spite of this, you contact
any obstruction when cutting,
turn off the Electric Lawn
Scarifier and remove the ob-
struction. Check the unit for
damage and have it repaired
if necessary.
A
Interruptions of Work
Never leave the Electric Lawn
Scarifier unattended at the
working area.
If you interrupt your work
store the unit in a safe place.
Disconnect the mains plug !
When you interrupt work in
order to go to another working
area, always switch off the
Electric Lawn Scarifier during
transport.
A
Check the Environment
Never use the unit when it is
raining or in damp or wet areas.
Do not operate your Electric
Lawn Scarifier near swimming
pools or garden ponds.
Please observe the prescribed
local quiet times.
A
Electric Safety
Keep the mains cable away
from the aerator !
Check the power cable re-
gularly for damage and signs
of wear and tear.
The Electric Lawn Scarifier
must only be operated with un-
damaged electric cable. If the
electric cable or the extension
cable is damaged disconnect
the mains plug immediately.
The socket of an extension
cable should be water-proof
or the connection sockets
for extension cables must be
8. Advice for Proper Use / Safety Instructions
To prevent tripping, take par-
ticular care when moving
backwards and when pulling
the scarifier.
3. When turning the scarifier, al-
ways turn the cable strain relief
device
8
on the guide handle
to the side you are working
on. This makes it considerably
easier to guide the cable.
4. When aerating areas of very
mossy lawn we recommend
re-sowing the lawn after aerat-
ing.
This helps the areas of lawn
which were replaced by moss
to regenerate more quickly.
5. After using the scarifier, dis-
connect the mains plug, re-
move the grass etc. from the
wheels and clean the aerator
cylinder.
Important ! Do not rinse the
scarifier with water.
Note: To prevent injury,
A
wear protective gloves!
6.2 Transport
Important ! Switch off the
motor, remove the mains plug
from the socket and wait until
the tool has stopped moving.
When moving the scarifier over
sensitive surfaces, e.g. tiles,
we recommend you carry the
scarifier.
A
Warning ! The aerator does
not stop immediately after
the motor has been turned off.
Danger of injury due to spring
prongs.
7.1 Adjusting the Aerator
(Fig. E / E 1)
Like every technical unit the Lawn
Scarifier has wear by using. The
more intensive use the bigger
will be natural abrasion. Hard and
heavy soils accelerate wear also
like over-proportional use of the
scarifier, e.g. by lending it often
or improper handling.
If the results of your work with
the aerator become increasingly
worse the aerator can be adjust-
ed up to two steps lower. If the
springs have worn down to the
bend (Fig. E 1) we recommend
you exchange the aerator as
described in "Exchanging the
Aerator".
Adjusting Positions
of the Aerator
The aerator has the following
adjusting positions:
Position 1
Position set at the factory
Position 2
First adjustment position after
wear (aerator lowered by 5 mm)
Position 3
Second adjustment position
after wear (aerator lowered by a
further 5 mm)
Adjusting the Position (Fig. E)
The adjusting unit
C
in the
centre of the wheels is optimally
factory pre-set (position
1 ).
Tip : Adjusting the aerator with-
out visible wear of springs could
damage the aerator.
If the aerator is worn it can be
adjusted as follows:
1.
Turn off the scarifier, remove
the mains plug from the
socket and wait until the
aerator has stopped turning.
Keep your hands and feet
away from the rotating parts.
2. Press the retaining spring
G
together and pull out the ad-
justment unit
C
on the right
hand side of the aerator in
the direction of movement
(i.e. on the right hand side
when standing behind the
aerator) approx. 6 mm.
3. Turn the adjustment unit
C
until the next highest number
is in the 12 o’clock position.
4. Re-attach the wheel to the axle
by pressing the middle of the
adjustment unit
C
until the
retaining spring
G
provides an
audible snap-in. The wheel is
now re-attached to the axle.
Note : If necessary remove
all dirt and contamination from
the recesses.
5. Repeat points 1- 4 with the
adjustment unit
C
o n the left
hand side of the aerator in
the direction of movement
(i.e. on the left hand side when
standing behind the aerator).
Important ! This time you
must turn the adjustment unit
C
in an anticlockwise direc-
tion.
Important information :
The aerator must be set to the
same number on both sides.
7.2 Exchanging the Aerator
(Fig. F)
After you have adjusted the
aerator twice (lowered twice)
the aerator cylinder must be ex-
changed. A new aerator cylinder
is available from GARDENA
Service, Art. No.
4097.
A
Warning ! Danger of in-
jury due to spring prongs.
Wear protective gloves.
Change the aerator as follows:
1.
Turn off the scarifier, remove
the mains plug from the
socket and wait until the
aerator has stopped rotating.
2. Turn the scarifier over so the
aerator cylinder is facing up-
wards (Fig. F).
3. Loosen the two screws
F
of the end plate
D
using a
Phillips screw driver (Fig. F).
4. Lift the wheel with the end
plate
D
diagonally until you
can remove the aerator from
the square bar
I
of the drive
shaft (Fig. F 1).
5. Remove the aerator
E
by
tilting and pulling it from the
receptacle square bar of the
drive shaft
