7.1 Maintenance

Maintenance includes all jobs
which keep your electric Hattrick
lawn mower in perfect working
order. By regularly checking the
unit (firm seating of screw con-
nections, 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.

Turn the Hattrick off
and disconnect from the

mains before cleaning or mak-
ing any adjustments to the

mower, or checking whether
the extension cable is entan-
gled or damaged. Danger of
injuries !

To avoid injury to persons
and material damage: Never
clean your electric Hattrick
lawn mower with running water,
in particular with water under
high pressure.

Store your electric Hattrick
lawn mower in a dry place
where it is protected from frost.
The lawn mower should be
stored out of the reach of
children.

Follow the manufacturer’s
instructions when replacing

the

blades or the aerator

cylinder.

6.4 Mowing with
the grass catcher

As soon as there are grass clip-
pings left on the lawn during
mowing and aerating, the grass
catcher should be emptied.

6.4.1 Grassbox HE 32

(ill. N)

Removing the grassbox

To remove the grassbox, lift the
safety cover (15) with one hand.
With the other hand use the
handle to remove the grassbox
(22).

If the protective cover is released
it automatically shuts and closes
the ejection opening.

If grass clippings stick in the ejec-
tion opening, pull the electric
Hattrick lawn mower back about
1 m so that the grass clippings
drop out and starting the motor
becomes easier.

Fitting the grassbox

Attention ! Attach the
grassbox only with the

motor switched off and the
cutting blades still.

With one hand lift the safety cover
(15); with the other hand hold the

handle of the grassbox (22) and
fit it to the holder.

Note: If properly seated, the
protective cover fits firmly to
the grassbox.

Please ensure that the protec-
tive cover does not open during
operation as foreign bodies
(such as grass cuttings) can
be thrown out.

Mowing without the grassbox

The Hattrick lawn mower can be
used without the grassbox with
the safety cover closed. The clip-
pings are put down on the lawn
below the safety cover.

6.4.2 Grass catcher HE 36 /
HE 40

(ill. D)

Removing the grass catcher

To remove the grass catcher (3)
lift the protective cover (15) on
your electric Hattrick lawn mower
with one hand. With the other
hand take the carrying handle (4)
and remove the grass catcher (3)
upwards.

If the protective cover (15) is re-
leased it automatically shuts and
closes the ejection opening.

If grass clippings stick in the
ejection opening, pull the electric

Hattrick lawn mower back about
1 m so that the grass clippings
drop out and starting the motor
becomes easier.

Note: To ensure good filling
volume regularly clean the
grass catcher inside and out-
side.

Attaching the grass catcher

Attach the grass catcher
only with motor switched

off and the cutting blades still.

Lift the protective cover (15) with
one hand. With the other hand
hold the grass catcher (3) at the
carrying handle (4) and insert
it into the fixing of the ejection
opening from above.

Note: If properly seated, the
protective cover (15) fits snugly
to the grass catcher (3).

Mowing without the grass
catcher

The Hattrick lawn mower can be
used without the grass catcher
with the protective cover (15)
closed. The clippings are put
down on the lawn below the pro-
tective cover.

6.1 General remarks
on the care of lawns

To keep your lawn at its best we
recommend you to cut it regularly
once a week. Depending on the
growth of moss and weeds, switch
on the aerator cylinder as well.
Frequent mowing and aerating
improves growth of the lawn and
makes the grass stronger.

Short clippings (up to a length
of about 1 cm) can be left on the
lawn. Longer clippings must be
removed to prevent the lawn
becoming yellow or matted.

Cut and aerate 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 (without switching on the
aerator cylinder) and then cut
at right angles with the desired
cutting height setting, optionally
with the areator cylinder switched
on.

6.2 Mowing
Only cut with sharp blades
so that the grass is not bruised
and turn yellow.

To obtain a clean cut guide the
electric Hattrick lawn mower at
an appropriate speed in lanes as
straight as possible. Ensure that
the lanes overlap by a few cen-
timetres so that no uncut strips
are left behind.

Adjusting the cutting height
Hattrick HE 32

(ill. J)

Hattrick HE 36 / HE 40

(ill. E)

The electric Hattrick lawn mower
has a central, infinite cutting
height adjustment via a turning
knob (12). In front of the turning
knob (12) there is a display (14)
indicating the set cutting height
in steps of 5 mm.

Hattrick HE 32:
cutting height range 25 - 55 mm

Hattrick HE 36:
cutting height range 30 - 70 mm

Hattrick HE 40:
cutting height range 30 - 80 mm

Note: When working on slopes,
always mow at right angles to
the slope. To prevent the elec-
tric Hattrick lawn mower from
sliding away, point it slightly
uphill.

Always keep the bottom side
of the mower casing clean
and remove grass deposits.
Deposits complicate the start-
up procedure and affect the
cutting result as well as ejec-
tion of the grass clippings.

6.3 Mowing with the aerator
cylinder
Hattrick HE 32

(ill. K)

Hattrick HE 36 / HE 40

(ill. F)

Switching the aerator cylinder
on/ off
Switch off the motor before
switching the aerator cylinder
on or off.

To switch on the aerator cylinder
set the rotary switch (13) to
position “

I”

To switch it off set the rotary
switch (13) to position “

0”

Remarks on mowing with the
aerator cylinder switched on

The aerator cylinder can be used
for pulling drainages, removing
matting and moss in the lawn
as well as for cutting flat-rooting
ranks.

If the grass is particularly tall,
before using the aerator, make a
pre-cut at the maximum cutting
height to prevent overload of the
lawn mower.

At the end of the cutting lane
or for turning round the electric
Hattrick lawn mower, tilt it slightly
by pressing onto the guide
handle. This way you can turn it
easily using the rear wheels with
the aerator cylinder running free.

After having aerated heavily
moss-covered areas, it is re-
commended to re-sow the lawn.
This will help the affected lawn
to recover quickly.

The aerator cylinder can be indi-
vidually used depending on the
needs and condition of the lawn.
The table below provides informa-
tion on the use of the aerator
cylinder.
