To do a check of the muffler

WARNING: Bear in mind that the exhaust

fumes from the engine are hot and may

contain sparks which can start a fire. Never

start the product indoors or near

combustible material!

WARNING: Never use the product indoors

or in spaces lacking proper ventilation.

Exhaust fumes contain carbon monoxide, an

odorless, poisonous and highly dangerous

gas.

WARNING: Never use a product with a

faulty muffler.

The muffler keeps noise levels to a minimum and sends

exhaust fumes away from the operator.
• Do a visual check for damage and deformation.
• Make sure that the muffler is correctly attached to

the product.

Fuel Safety

WARNING: Read the warning instructions

that follow before you use the product.

• Never start the product if you spill fuel on it. Wipe the

spillage of and allow remaining fuel to evaporate.

• Never start the product if you spill fuel on yourself or

your clothes. Change your clothes and wash any

part of your body that has come in contact with fuel.

Use soap and water.

• Never start the product if the product is leaking fuel.

Check regularly for leaks from the fuel cap and fuel

lines.

• Always put the product on a flat surface and make

sure the cutting attachment cannot come in contact

with any object while you add fuel.

• Take care when handling fuel. Bear in mind the risk

off fire, explosion and inhaling fumes.

• Observe caution when handling fuel and make sure

there is adequate ventilation. Fuel and fuel fumes

are highly inflammable and can cause serious injury

when inhaled or allowed to come in contact with the

skin.

• Mix and pour fuel outdoors, where there are no

sparks or flames.

• Do not smoke or place hot objects near fuel.
• Always stop the engine and let it cool off for a few

minutes before you refuel.

• Open the fuel cap slowly so that any excess

pressure is released gently when you refuel.

• Tighten the fuel cap carefully after you refueled.
• Clean the area around the fuel cap. Contamination in

the tank can cause operating problems.

• Always move the product 3m (10ft) or further from

the refuelling area and source before starting.

Safety instructions for maintenance

WARNING: Read the warning instructions

that follow before you use the product.

• Only use cutting attachments with the guards we

recommend. 

• Always stop the engine before you do any work on

the cutting attachment. The cutting attachment

continues to rotate even after the throttle has been

released. Ensure that the cutting attachment has

stopped completely and disconnect the spark plug

before you start to work on it.

• A faulty cutting attachment may increase the risk of

accidents.

• Make sure that the trimmer cord is wound tightly and

evenly around the drum, otherwise the product will

generate harmful vibration.
