General working instructions

IMPORTANT!

This section describes the basic safety pre- cautions for working with trimmers. If you encounter a situation where you are uncer- tain how to proceed you should ask an ex- pert. Contact your servicing dealer.

Avoid all usage which you consider to be beyond your capability.

You must understand the difference between forestry clearing, grass clearing and grass trimming before use.

Basic safety rules

1. Look around you:

STo ensure that people, animals or other things cannot affect your control of the

machine.

STo ensure that people, animals, etc., do not come into contact with the cut- ting attachment or loose objects that are thrown out by the cutting attach- ment.

SCAUTION! Do not use the machine unless you are able to call for help in the event of an accident.

2.Do not use the machine in bad weather, such as dense fog, heavy rain, strong wind, intense cold, etc. Working in bad weather is tiring and often brings added risks, such as icy ground, unpredictable felling direction, etc.

3.Make sure you can move and stand safely. Check the area around you for possible ob- stacles (roots, rocks, branches, ditches, etc.) in case you have to move suddenly. Take great care when working on sloping ground.

4.Switch off the engine before moving to another area. Fit the transport guard before carrying or transporting the equipment any distance.

5.Never put the machine down with the engine running or while the cutting attachment is rotating.

The ABC of clearing

SAlways use the correct equipment.

SMake sure the equipment is well adjusted. S Follow the safety precautions.

S Organise your work carefully.

S Always use full throttle when starting to cut with the blade.

S Always use sharp blades. S Avoid stones.

WARNING: Neither the operator of the machine nor anyone else may attempt to remove the cut ma- terial while the engine is running or the cutting equipment is rotating, as this can result in serious injury. Stop the engine and cutting equip- ment before you remove material that has wound around the blade shaft as otherwise there is a risk of injury. The bevel gear can get hot during use and may remain so for a while afterwards. You could get burned if you touch it.

WARNING: Watch out for thrown objects. Always wear ap- proved eye protection. Never lean over the cutting attachment guard. Stones, rubbish, etc. can be thrown up into the eyes causing blindness or serious injury. Keep unautho- rised persons at a distance. Chil- dren, animals, onlookers and help- ers should be kept outside the safety zone of 15 metres. Stop the machine immediately if anyone ap- proaches. Never swing the ma- chine around without first checking behind you to make sure noone is within the safety zone.

WARNING: Sometimes branches or grass get caught between the guard and cutting attachment. Always stop the engine before cleaning.

Basic working techniques

SAlways slow the engine to idle speed after each working operation. Long periods at full throttle without any load on the engine can lead to serious engine damage.
