Thank you for purchasing a Lawn Star Petrol Trimmer which is one of the finest and most advanced products 
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.   

 
SAFETY PRECAUTIONS 

Inspect your trimmer and all its parts 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. Have the trimmer repaired only by an 
authorised repairer. Use only genuine Lawn Star replacement nylon cutting line 2.40 mm ( Part No. 80-24000 ), 
never metal. 
WARNING: Petrol and its vapours are highly flammable. Always stop the engine before refuelling. Do not 
smoke or light any flames while refuelling. Wipe off any fuel that may have spilled. Start the engine away from 
the place where it was refuelled. Ensure the tank cap is tightened properly. Return the trimmer to its normal 
operating position before starting. 
CAUTION: Exhaust fumes are toxic and asphyxiating. Inhalation may be lethal. Do not start the engine in 
closed or poorly ventilated environments. 

It is essential that the operator wears safety goggles, face shield, gloves, ear muffs, shoulder harness, 
protective clothing and sturdy, non-slip footwear with toe-protector. 

Do not use your trimmer for any jobs other than to cut grass and weeds. Do not use unless adequately guarded. 
Do not force your trimmer. If the engine labours, pull away from grass. 
Do not operate trimmer without a line-trimming blade as over-extended line is dangerous and will damage 
engine and invalidate warranty. 
Use care in picking up or holding the unit. Always hold the trimmer with both hands. Do not grasp the line-
trimming blade located at the edge of the underneath side of safety guard. 
Inspect the area to be cut and remove all debris that could be entangled in the cutting head. Also remove any 
object that the unit may sling during cutting. 
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 is maintained. 
Do not operate trimmer when tired, ill, or under the influence of alcohol, drugs or medication. 
Keep hands and feet clear of the rotating cutting head while unit is in use. Cutting elements continue to rotate 
for a few seconds after switch-off. 
Do not allow children under 16, nor anyone who is not familiar with these instructions to use the trimmer. 
Children, pets and onlookers should be kept at least 15 meters away from the work area, unless shielded by an 
effective solid barrier. 
Before storage allow the engine to cool. Store the unit indoors in a dry, ventilated and locked place, out of reach 
of children.
