Thank you for purchasing the Lawn Star Lawnmower which is one of the finest and most advanced
lawnmowers today’s technology can produce. Before you begin using it, please read this manual carefully
and familiarise yourself with the control and the proper use of this product to ensure you get the best
possible performance from it. The operator or user is responsible for accidents or hazards occurring to other
people or their property.
SAFETY PRECAUTIONS
Inspect your lawnmower and its supply/extension cable before each operation. If any part is damaged or
worn, repair or replace before operation. Do not operate with damaged, coiled or tangled supply/extension
cable. Keep cable away from the cutting blade.
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-256-00.
WARNING : To prevent electrical shock hazards, use only extension cables suitable for outdoor use with
splash-proof socket outlets, preferably protected by a sensitive Residual Current Device (RCD) with
tripping current of not more than 30 mA.
Pull the plug from the socket whenever you leave the machine unattended, before clearing a blockage,
before checking, before cleaning or working on the appliance, before changing parts such as the blade,
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, store the unit indoors in a dry and locked place, out of reach of children.
PREPARATIONS FOR USE
Remove the lawnmower, handles, grass catcher and all other contents from the box. Remove the spanner,
bolts and nuts supplied from the bag.
Unfold the handles and tighten the knobs (Fig.1).Attach the handle ends to the lawnmower chassis, insert
the four bolts provided and tighten the nuts using the spanner (Fig.2 No.1). Note: ensure the bolts point
outwards.
Assemble the two parts of the grass catcher (Fig.3) making sure that all the clips are fully clicked into
position.
Lift the rear guard flap (Fig.4 No.1) and attach the grass catcher (Fig.4 No.2) ensuring that the grass
catcher latches onto the two mounting hooks.

CARE, MAINTAINANCE, STORAGE AND TRANSPORT
Do not oil –this is unnecessary.
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.
Check the blade regularly. If it is damaged or worn replace with a genuine Lawn Star replacement blade
(Part No. M-256-00).
Check the grass catcher box regularly for damage and replace if necessary.
Store in a dry place out of reach of children and unauthorised persons.
OPERATING INSTRUCTIONS
Attach extension cord with suitable female coupler to the plug provided on the lawnmower. Insert a loop
of the extension cord into the strain-relief mechanism provided on the handle (Fig.5) to prevent accidental
detachment of plug. Press and hold the safety lock-off button on the switch with a left hand finger (Fig.6
No.1), and then grip the switch lever with your right hand and pull it towards the handle (Fig.6 No.2).
Continue to grip the lever and release the button and begin to mow your lawn. To stop the motor simply
release the switch lever. Do not use the switch lever intermittently. This will damage it.
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.
Start mowing at the edge of the lawn closest to the plug point and work your way away from the plug
(Fig.7).This will lay-out the cable on the lawn you have already cut and will keep it out of your way.
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
will penetrate deeper into the soil in search of this moisture.
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 is potentially dangerous 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 reach maximum RPM before cutting grass. Starting the motor in tall grass will
overload it and will trip your circuit breaker.
Periodically clean the under side 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.
The lawnmower motor is fitted with a thermal cut-out switch which switches off the motor if it overheats
due to overloading. In the event that this happens, switch off the mower, disconnect the power supply and
allow the motor to cool for approx 20 minutes.
REPLACING THE CUTTING BLADE
Disconnect the lawnmower from the power supply and turn it 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.8). Remove the bolt, spring washer, blade washer and blade. Inspect and replace damaged
or worn parts. Re-assemble in the reverse order and ensure the blade bolt is securely tightened.
ENSURE THE BLADE IS CORRECTLY ASSEMBLED AND TIGHTENED, AND THAT THE
MOWER IS RETURNED TO ITS NORMAL POSITION BEFORE USING.
