SAFETY PRECAUTIONS
Inspect your lawnmower before each operation. If any part is damaged or worn, repair or replace before
operation. Use only genuine Lawn Star (Pty) Ltd. replacement parts when servicing or repairing the
unit. These parts are available from your supplying dealer or service agent. Use only genuine Lawn Star
replacement cutting blade Part No. M-256-20 or mulching blade Part No. M-255-10.
WARNING : Remove the safety key from the socket whenever you leave the machine unattended.
Remove safety plug(Fig.9-4) and batteries before clearing a blockage, before checking, before cleaning
or working on the appliance, before changing parts such as the blades, after striking a foreign object
(inspect the appliance for damage and make repairs as necessary) or if the appliance starts to vibrate
abnormally (check immediately).
The operator must wear protective clothing, long trousers and sturdy, non-slip footwear.
Do not operate the mower when barefoot or wearing open sandals.
Do not use your lawnmower for any jobs other than those for which it was intended.
Do not use unless the entire grass catcher is attached or the rear guard is in place.
Do not switch on mower unless all four wheels are resting squarely on the lawn being mowed. Do not
tilt or lift mower while switched on. Switch off mower before pushing over surfaces other than grass.
Do not force your lawnmower. If motor labours, mow in multiple passes at different height settings.
Keep hands and feet well clear of rotating blades while the mower is in use. Cutting blades continue to
rotate for a few seconds after switch-off. Never pick up or carry mower while the motor is running.
Inspect the area to be cut and remove all debris that could be entangled in the cutting blades. Also
remove any solid objects, e.g. stones, sticks, wires and bones that the unit may sling during cutting.
Exercise extreme caution when mowing and changing direction. Always walk, never run. Never cut
grass by pulling the mower towards yourself. Do not walk backwards while mowing, you may trip.
Avoid dangerous environments. Do not use the unit in poor light or in damp or wet locations. Do not
use in the rain. Do not use on steep slopes, especially if damp. Work across slope faces, not up and
down. Do not over-reach. Ensure good footing and balance are maintained.
Never operate the lawnmower when you are tired, ill or under the influence of alcohol or drugs.
Do not allow children or people unfamiliar with these instructions to use the lawnmower. Local
regulations may restrict the age of the operator. Children, pets and onlookers should be kept at least 15
meters away from the work area, unless shielded by an effective solid barrier.
When not in use, remove batteries and safety plug and store the unit indoors in a dry and locked place,
out of reach of children.

CHARGING BATTERIES
1. Take the battery pack out of the equipment.
1. Do this by pressing the push-lock button and pulling the battery out (Fig.5).
2. Check that your mains voltage is the same as that marked on the rating plate of the battery charger.
Insert the power plug of the charger into the socket outlet. The green LED will then begin to flash.
3. Insert the battery pack into the battery charger (Fig.6).
4. In the section entitled “Battery capacity indicator” you will find a table with an explanation of the
LED indicator on the batteries.
5. See Table 1 for explanation of LED indicators on charger unit.
The battery pack may become a little warm during charging. This is normal.
If the battery pack fails to charge, check:
If the battery pack is warm, let it cool and try again
whether there is voltage at the socket outlet
whether the battery is correctly fitted to charger and the charging contacts are clean.
If the battery pack still fails to charge, contact our customer service centre for assistance.
To ensure that the battery pack provides long service, you should take care to recharge it promptly. You
must recharge the battery pack when you notice that the performance of the device drops. Always store
the battery in the fully charged state. Never allow the battery pack to become fully discharged. This will
cause it to develop a defect!
INSTALLING THE BATTERY (Fig. 5)
Open the battery cover. Then insert the batteries in the mounts as shown in (Fig. 5).
For optimum mowing results and battery power performance it is always best to use
batteries with the same capacity of 3.0 Ah or higher. There is also the option of using
batteries with different capacities in the two battery mounts A and B (Fig.8) which are
opposite each other.
Always make sure, however, that you only use batteries of the same capacity in each
separate battery bank (Fig. 8).
For example, you could use 2 x 4.0Ah batteries in one battery bank(A) while using 2 x
3.0Ah batteries in the opposite battery bank(B).
Important!
Use only batteries which are charged to the same level. Never combine full and half-full
batteries. Always charge the two/all batteries simultaneously. The equipment‘s operating
time depends on the battery with the lower charge level. The two/all batteries must always
be fully charged before use. Close the battery cover by swinging it down, and make sure that
it latches in place correctly.

BATTERY CAPACITY INDICATOR (Fig. 7)
Press the switch for the battery capacity indicator (Fig. 7-A) . The battery capacity indicator
(Fig. 7-B) shows the charge status of the battery using 3 LEDs.
All 3 LEDs are lit:
The battery is fully charged.
2 or 1 LED(s) are lit:
The battery has an adequate remaining charge.
1 LED blinks:
The battery is empty, recharge the battery.
All LEDs flash:
The battery pack has undergone exhaustive di- scharge and is defective. Do not use or
charge a defective battery pack!
Caution!
Do not park the lawn mower in the sun. Batteries which have been inserted could heat up to in-
admissible levels.
CARE, MAINTAINANCE, STORAGE AND TRANSPORT
Hazard!
Pull out the safety plug and remove all the battery packs before transporting, storing or starting
any maintenance work on the mower.
Do not oil –this is unnecessary.
Do not clean the lawn mower with running water, particularly with high-pressure water.
We recommend cleaning the equipment immediately each time after use.
Clean the equipment regularly with a damp cloth and some soft soap. Do not use cleaning agents or
solvents; these may be aggressive to the plastic parts in the equipment. Ensure that no water can get into
the interior of the equipment.
Keep air intake vents, in plastic motor housing, free of grass cuttings and dirt to ensure unobstructed
cooling air-flow through the motor. Clogged-up air intake vents cause the motor to overheat and can
result in failure.
Keep all nuts, bolts and screws tightened to ensure that the appliance is in a safe working condition.
Replace worn or damaged parts for safety.
The blade is subjected to more wear and tear than any other component. Therefore, routinely check the
condition of the blade and make sure that it is tightly fastened. If the blade is worn, it must be
immediately replaced with genuine Lawn Star replacement blades.
Low energy bar blade Part No. M-256-20
Mulching blade Part No. M-255-10.
An excessively vibrating mower means that the blade is not properly balanced or has become deformed
from striking an object. In this case, the blade must be replaced.
Check the grass catcher box regularly for damage and replace if necessary.
Store in a cool dry place out of reach of children and unauthorised persons.

OPERATING INSTRUCTIONS
Caution!
The lawn mower is equipped with a safety switch to prevent unauthorized use. Directly before
starting up the lawn mower insert the safety plug (Fig.9-4) and remove the safety plug again
when interrupting or terminating your work.
Important!
For safety reasons this mower is fitted with an angle sensor. It will not be possible to start the
cordless lawn mower if the pitch angle is over ~70° ± 10°.
To prevent the equipment switching on accidentally, the lawn mower is equipped with a safety switch
(Fig. 9-3) which must be pressed before the switching bar (Fig. 9-1) can be activated.
Note: It will take a few second for the motor to start once the switching bar has been activated.
To begin mowing your lawn, continue to grip the switching bar (Fig. 9-1) and release the safety
switch (Fig. 9-3). The lawn mower switches itself off when the switching bar is released. After the
motor starts the speed will drop after a few seconds when in idle mode and will rise again when in
working mode. Repeat this process several times so that you are sure that the machine functions
properly. Do not use the switch lever intermittently as this will damage it.
Tilt the mower slightly over backwards when starting the mower in long grass this reduces the load on
the motor during start-up.
Warning! Never open the chute flap or remove the grass box when engine is still running. A
rotating blade can cause serious injuries!
Always remove the safety plug (Fig. 9-4) first before removing the grass box.
Before you perform any repair or maintenance work on the equipment, ensure that the blade is not
rotating, that the safety plug is disconnected and that the batteries have been removed.
MOWING PROCEDURES
The ideal time to mow your lawn is in the cooler late afternoon. The grass is dry and the sensitive new
cut area is not exposed to direct sun.
Cut your lawn at the same height most of the time. Adjust the cutting height (Fig.2 No.2) based on the
weather. If your lawn is getting a lot of water you can cut a little closer. If the temperature is high and
things are dry, allow the grass to grow a little longer so that the soil retains more moisture and the roots
Tall and thick grass should be cut in multiple passes with the mower set at different heights.
Best results are achieved with regular mowing. Do not let the grass grow too long between mowings
and do not set the cutting height too low as this will scalp the lawn.
Avoid cutting wet grass as this will overload the motor and will block the discharge chute.
Ensure that the blades are sharp. A sharp blade makes a nice clean cut. A dull blade shatters the leaf
and impairs the healthy growth of your lawn.
To improve the appearance of your lawn, alternate your cutting pattern.
CAUTION
Avoid excessive intermittent switch operation during mowing as this will damage the switch.
Allow the motor to run for 5 seconds before cutting grass. Starting the motor in tall grass will overload
it push down on the handle to slightly lift the front of the mower out of the grass when starting the
mower. Periodically clean the underside of the mower chassis with a brush. Built–up grass cuttings
become corrosive when they decompose and will promote rust. Do not use water to clean. Wear gloves.

REPLACING THE CUTTING BLADES
Disconnect the lawnmower safety plug and remove all the batteries and turn the mower on its side.
Hold the cutting blade firmly with one hand and loosen the centre bolt with the spanner provided, by
turning it in an anti-clockwise direction (Fig.10). Tit new blade and Re-assemble in the reverse order
and ensure all bolts and nuts are securely tightened.
ENSURE BLADES IS CORRECTLY ASSEMBLED AND TIGHTENED BEFORE USING.
