SYMBOLS
The following symbols are displayed on the ma-
chine in order to remind you about the safety pre-
cautions and attention necessary when using the
machine.
The symbols mean:
Warning! Read the Instruction Book and
Safety Manual before using the machine.
Warning! Keepspectatorsaway. Beware of
objects being flung out.
Warning! Take out the safety key before
any type of maintenance is carried out.
Warning! Do not put hands or feet under
thecover of the machinewhen it isrunning.
Warning! The blades continue to rotate
even after the machine has been switched
off.
When a red lamp lights up on the mower’s
control panel and/or a sound signal is acti-
vated, take out the safety key.
ASSEMBLY
WHEELS/CUTTING HEIGHT (fig. 1)
1. Insert the wheel bolt A in the hub cap B.
2. Snap-on the centre cup C.
3. Place abushing on each sideof thewheels (only
the back wheels).
4. Fit the wheel in one of the fixing plate's fourpo-
sitions.
5. Tighten securely by hand using the finger-grip
holes in the hub cap.
Note! The same cutting height should be set on all
four wheels.
STEERING (fig. 2)
1. Insert the tubes into the ends of the handlebar.
2. Fit the screws. Tighten securely.
3. Insert the ends of the U tubeinto theholes inthe
chassis.
4. Fit the screws. Tighten securely.
5. Attach the handle to the U tube using the bolts,
washers and locking knobs provided. The han-
dlebar can be folded forwards by undoing the
locking knobs slightly. This reduces the space
the mower takes up during transport, etc.
6. Secure the electrical cable into the cable holder.
7. Fix the electrical cable using a cable tie.
GRASS COLLECTOR (fig. 3)
1. Snap-together the grass collector's upper and
lower parts.
2. Open the cover on the machine and hook the
grass collector onto the chassis.
Note! The lawn mower can be used without the
grass collector. The grass will then collect in a
bead behind the machine.
BATTERY
GENERAL
Before starting the mower for the first
timeand after winterstorage,you should
charge the battery for 1 - 2 days other-
wise the battery can be damaged.
In order for the battery to maintain its
capacity and to give optimum perform-
ance, it is important that the charging
and storage instructions are carefully fol-
lowed.
• The battery used in this machine is a lead-acid
type battery. This type of battery must always
be stored fully charged.
• Always charge the battery indoors, in a garage,
etc. where the battery is dry and protected from
the weather.
• Only charge the battery when the temperature is
at least 0°C and not over +40°C. Charging in
lowerorhighertemperaturescandamagethe
battery.
STOP

ENGLISH GB
• Always keep the mower battery away from wa-
ter, sources of heat (ovens, radiators, open fires,
etc.) and hazardous chemicals.
• Always use the accompanying genuine Stiga
charger. Never use the charger for any other
product.
• Never use the charger if itis damaged in any way.
A damaged lead or charger should immediately
be replaced at an authorised service workshop
• Take care of the leads. Never carry the charger
by the lead. When chargingis complete pull out
the plug not the lead. If an extension cable is
used, use a robust sort suitable for outdoor use,
even if the battery is never charged outdoors.
• The charger always feels warm to touch, during
the first hours of charging.
CHARGING BEFORE WINTER
STORAGE
The battery should always be stored ful-
ly charged.
1. Take the battery out of the mower.
2. Carefully wipe off the battery.
3. Store the battery outside of the mower in a dry
and cool place.
USING THE MOWER
STARTING/STOPPING THE MOWER
Keep hands and feet well away from the
rotating blade(s). Never put your hand
or foot under the blade casing or in the
grass ejector unit while the motor is
running.
1. Fix the battery in place in the mower (fig. 6).
2. Insert the safety key into the control panel (fig.
7). When the safety key is in place, the green
lamp willbe lit. If it is not, check that the engine
protection onthe safety key ispressed in (fig. 8)
and that the battery is fully charged.
3. Press down the handle to lift the front wheels off
thegrass,therebyreducinggrassresistanceinthe
starting moment.
4. Press in the power on/off button 1(fig. 9). Start
the engine by pressing in the safety handle 2.To
stop, release the safety handle.
After finishing mowing:
1. Removethesafetykeyandkeepitoutofreach
of children.
2. Clean the mower (see the “Maintenance” sec-
tion under the heading “Cleaning”).
3. Recharge the battery once it has cooled down
(after about 30 minutes).
If the safety handle has stopped work-
ing, remove the safety key and take the
mower to an authorised service work-
shop to be repaired.
CONTROL PANEL (fig. 5)
The control panel has the following functions:
1. It includes the socket for the safety key. The safe-
ty key also has an in-built engine protection. If
the engine protection has been activated, remove
the safety key and reset the engine protection
(fig.8).
2. It includes three lamps which indicate the bat-
tery’s charge level:
AGreen = the battery is charged to between 30%
and 100% of full capacity.
CHARGING INSTRUCTIONS
The battery must always be charged
directlyafter finishingmowingandas
soon as it has cooled down (after
about 30 minutes).
1. Charge the battery outside of the mower in a
dry and cool place.
2. Firstconnecttheroundplugfromthechargerto
the battery (fig. 4).
3. Then connect the charger to a wall socket
(~220/230V).
4. Chargefor 1- 2 days, depending on howlong
the machine has been used. Whilst thebattery
ischarging,theredcharginglamponthebat-
tery is continuously lit, for as long as the bat-
tery charger is connected
5. Finishcharging by firstly pullingoutthe plug
from the wall socket.
If the charger is first removed from
the battery, the plug leads can short-

ENGLISH GB
BYellow = the battery’s power has reduced. Be-
tween 5% and 30% remains.
CRed = 5% or less of the battery power remains.
The machine will begin to beep and will switch
itself off automatically. Stop mowing and re-
charge the battery once ithas cooled down(after
about 30 minutes). Do not use the mower again
until the battery is fully charged.
Important: do not allow the battery power to com-
pletelyrundownasthismaydamagethebatteryand
shorten its operational life.
MOWING TIPS
For best cutting results and to ensure that the bat-
tery lasts as long as possible, the following rules
should be followed:
• Drive the mower at a slow and even pace
• Try to avoid excessive starting and stopping, as
this draws a lot of current.
• Make surethat the motor isrunning at full speed
at all times when mowing.
• Mow regularly and often, especially when the
grass is growing quickly. Donotmowmore than
a third of the total height of the grass during one
mowing session.
• Always use a sharp blade.
• Do not use the mower when it is raining or when
the grass is wet.
• Make surethat the underside ofthe cutting deck
is kept clean.
MAINTENANCE
Take out the safety key and remove the
batterybeforeanytypeofmaintenanceis
carried out.
CLEANING
The mower should be cleaned after each use. Use a
moistened cloth or sponge and a mild soap solution.
Do not clean with water or solvents. Remove all
grass clippings which might have gathered on the
underside of the deck and in the ejector.
The grass collector, although not the mower it-
self, can be cleaned with water. Grass collection ef-
ficiency is reduced if the holes are blocked.
CHANGING THE BLADE
Check,beforeandaftereachuse,thatthe
blade is tightly fixed and that it is not
damaged. A bent or damaged blade
should immediately be replaced. Use pro-
tective gloves to avoid cutting injuries.
Blunt and/or damaged blades tear off the grass and
make the lawn look ugly after mowing. New, well-
sharpened blades cut off the grass and ensure that it
looks green and fresh after it has been mown.
Remove the battery. Put the accompanying wrench
(36 mm) on the hexagon holder. Loosen the blade
nut with an adjustable wrench or another type of
fixed wrench (19 mm) (fig. 10). Turn the blade nut
in an anti-clockwise direction in order to remove the
blade.
Fit the new blade and refit all the other parts exactly
as they were before they were dismantled, see fig.
10. Tighten the blade nut fully.
SHARPENING THE BLADE
Water grinding with whetstone or a grinding stone
should be used to sharpen the blade.
For safety reasons, the blade should not be sharp-
ened on an emery wheel. Too high a temperature
can result in the blade becoming brittle.
If the blade is sharpened, it must be bal-
anced afterwards to avoid vibration
damage (fig. 11).
