General working instructions

IMPORTANT!

This section describes the basic safety precautions for working with clearing saws and trimmers.

If you encounter a situation where you are uncertain how to proceed you should ask an expert. Contact your dealer or your service workshop.

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:

•To ensure that people, animals or other things cannot affect your control of the machine.

•To ensure that people, animals, etc., do not come into contact with the cutting attachment or loose objects that are thrown out by the cutting attachment.

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

2Do 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.

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

4Take great care when cutting a tree that is under tension. A tree that is under tension may spring back to its normal position before or after being cut. If you position yourself incorrectly or make the cut in the wrong place the tree may hit you or the machine and cause you to lose control. Both situations can cause serious personal injury.

5Switch off the engine before moving to another area. Fit the transport guard before carrying or transporting the equipment any distance.

6Never put the machine down with the engine running unless you have it in clear sight.

The ABC of clearing

•Always use the correct equipment.

•Make sure the equipment is well adjusted.

•Follow the safety precautions.

•Organise your work carefully.

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

•Always use sharp blades.

•Avoid stones.

•Control the felling direction (take advantage of the wind).

WARNING! Neither the operator of the

!machine nor anyone else may attempt to remove the cut material while the engine is running or the cutting equipment is rotating, as this can result in serious injury.

Stop the engine and cutting equipment 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 burnt if you touch it.

WARNING! Watch out for thrown objects.

!Always wear approved 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 unauthorised persons at a distance. Children, animals, onlookers and helpers should be kept outside the safety zone of 15 m. Stop the machine immediately if anyone approaches. Never swing the machine around without first checking behind you to make sure no-one is within the safety zone.

WARNING! Sometimes branches or grass

!get caught between the guard and cutting attachment. Always stop the engine before cleaning.

Working methods

WARNING! Avoid cutting with the area of the

!blade between the 12 o’clock and 3 o’clock positions. Because of the speed of rotation of the blade kickback can occur if you attempt to cut thick stems with this area of the blade.

•Before you start clearing, check the clearing area, the type of terrain, the slope of the ground, whether there are stones, hollows etc.

•Start at whichever end of the area is easiest, and clear an open space from which to work.
