SAFETY INSTR UCTIONS

Impor tant Personal protective equipment

IMPORTANT!
The machine is only designed for trimming grass, grass clearing and/or forestry clearing.
The only accessories you can operate with this engine unit are the cutting attachments we recommend in the chapter on Technical data.
Never use the machine if you are tired, if you have drunk alcohol, or if you are taking medication that could affect your vision, your judgement or your co-ordination.
Never use the machine in extreme weather conditions such as severe cold, very hot and/or humid climates.
Wear personal protective equipment. See instructions under the heading Personal protective equipment.
Never use a machine that has been modified in any way from its original specification.
Never use a machine that is faulty. Carry out the checks, maintenance and service instructions described in this manual. Some maintenance and service measures must be carried out by trained and qualified specialists. See instructions under the heading Maintenance.
All covers, guards and handles must be fitted before starting. Ensure that the spark plug cap and ignition lead are undamaged to avoid the risk of electric shock.
The machine operator must ensure that no people or animals come closer than 15 metres while working. When several operators are working in the same area the safety distance should be at least twice the tree height and no less than 15 metres.
IMPOR TANT!
A clearing saw, brushcutter or trimmer can be dangerous if used incorrectly or carelessly, and can cause serious or fatal injury to the operator or others. It is extremely important that you read and understand the contents of this operator’s manual.
You must use approved personal protective equipment whenever you use the machine. Personal protective equipment cannot eliminate the risk of injury but it will reduce the degree of injury if an accident does happen. Ask your dealer for help in choosing the right equipment.
ARNING! Listen out for warning signals or
shouts when you are wearing hearing
!
protection. Always remove your hearing protection as soon as the engine stops.
HELMET
A helmet should be w orn if the trees being cleared are taller than 2 m.
HEARING PROTECTION
Wear hearing protection that provides adequate noise reduction.
ARNING! The ignition system of this
machine produces an electromagnetic field
!
during operation. This field may under some circumstances interfere with pacemakers. To reduce the risk of serious or fatal injury, we recommend persons with pacemakers to consult their physician and the pacemaker manufacturer before operating this machine.
ARNING! Running an engine in a confined
or badly ventilated area can result in death
!
due to asphyxiation or carbon monoxide poisoning.
ARNING! Never allow children to use or be
in the vicinity of the machine. As the
!
machine is equipped with a spring-loaded stop switch and can be started by low speed and force on the starter handle, even small children under some circumstances can produce the force necessary to start the machine. This can mean a risk of serious personal injury. Therefore remove the spark plug cap when the machine is not under close supervision.
EYE PROTECTION
Always wear approved eye protection. If you use a visor then you must also wear approved protective goggles. Approved protective goggles must comply with standard ANSI Z87.1 in the USA or EN 166 in EU countries.

ARNING! Never use a machine with faulty
safety equipment. The machine’s safety
!
equipment must be checked and maintained as described in this section. If your machine fails any of these checks contact your service agent to get it repaired.

Thr ottle lockout

The throttle loc kout is designed to prevent accidental operation of the throttle control. When you press the lock (A) (i.e. when you grasp the handle) it releases the throttle control (B). When you release the handle the throttle control and the throttle lockout both move back to their original positions. This movement is controlled by two independent return springs. This arrangement means that the throttle control is automatically locked at the idle setting.
A
B
See instructions under the heading Start. Start the machine and apply full throttle. Release the throttle and check that the cutting attachment stops and remains at a standstill. If the cutting attachment rotates with the throttle in the idle position then the carburettor idle setting must be checked. See instructions under the heading Maintenance.

Stop s witch

Use the stop s witch to switch off the engine.
Start the engine and make sure the engine stops when you move the stop switch to the stop setting.

Cutting attachment guard

This guard is intended to prevent loose objects from being thrown towards the operator. The guard also protects the operator from accidental contact with the cutting attachment.
Check that the guard is undamaged and not cracked. Replace the guard if it has been exposed to impact or is cracked.
Always use the recommended guard for the cutting attachment you are using. See chapter on Technical data.
WARNING! Never use a cutting attachment without an approved guard. See the chapter
!
on Technical data. If an incorrect or faulty guard is fitted this can cause serious personal injury.
Regularly check the vibration damping units for cracks or deformation. Check that the vibration damping element is undamaged and securely attached.
WARNING! Overexposure to vibration can lead to circulatory damage or nerve damage
!
in people who have impaired circulation. Contact your doctor if you experience symptoms of overexposure to vibration. Such symptoms include numbness, loss of feeling, tingling, pricking, pain, loss of strength, changes in skin colour or condition. These symptoms normally appear in the fingers, hands or wrists. The risk increases at low temperatures.

Quick release

There is an easily accessible, quick release fitted at the front as a safety precaution in case the engine catches fire, or in any other situation that requires you to free yourself from the machine and harness. See instructions under the heading Adjusting the harness and clearing saw.

Vibration damping system

Your machine is equipped with a vibration damping system that is designed to reduce vibration and make operation easier.
Using incorrectly wound cord or a blunt or incorrect cutting attachment (wrong type or incorrectly filed, see instructions under the heading Filing the blade) increases the level of vibration.
The machines vibration damping system reduces the transfer of vibration between the engine unit/cutting equipment and the machines handle unit.
Check that the harness straps are correctly positioned. Once the harness and machine have been adjusted, check that the harness quick release works correctly.
Muffler
The muffler is designed to keep noise levels to a minimum and to direct exhaust fumes away from the user. A muffler fitted with a catalytic converter is also designed to reduce harmful exhaust gases.
In countries that have a warm and dry climate there is a significant risk of fire. We therefore fit certain mufflers with a spark arrestor screen. Check whether the muffler on your machine is fitted with this kind of screen.
For mufflers it is very important that you follow the instructions on checking, maintaining and servicing your machine.
English
SAFETY INSTRUCTIONS
Never use a machine that has a faulty muffler.
Regularly check that the muffler is securely attached to the machine.
If the muffler on your machine is fitted with a spark arrestor screen this must be cleaned regularly. A blocked screen will cause the engine to overheat and may lead to serious damage.

Locking nut

A locking nut is used to secure some types of cutting attachment.
When fitting, tighten the nut in the opposite direction to the direction of rotation of the cutting attachment. To remove it, undo the nut in the same direction as the cutting attachment rotates. (CAUTION! The nut has a left-hand thread.) Tighten the nut using the socket spanner.
WARNING! Mufflers fitted with catalytic converters get very hot during use and
!
remain so for some time after stopping. This also applies at idle speed. Contact can result in burns to the skin. Remember the risk of fire!
WARNING! The inside of the muffler contain chemicals that may be carcinogenic. Avoid
!
contact with these elements in the event of a damaged 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 machine indoors or near combustible material!
When loosening and tightening the saw blade nut, there is a risk of injury from the teeth of the saw blade. You should therefore always ensure that your hand is shielded by the blade guard when doing this. Always use a socket spanner with a shaft that is long enough to allow this. The arrow in the diagram shows the area where you should operate the socket spanner when loosening or tightening the nut.
The nylon lining inside the locking nut must not be so worn that you can turn it by hand. The lining should offer a resistance of at least 1.5 Nm. The nut should be replaced after it has been put on approx. 10 times.

SAFETY INSTRUCTIONS

Cutting equipment

This section describes how to choose and maintain your cutting equipment in order to:
Reduce the risk of blade thrust.
Obtain maximum cutting performance.
Extend the life of cutting equipment.
IMPORTANT!
Only use cutting attachments with the guards we recommend! See the chapter on Technical data.
Refer to the instructions for the cutting attachment to check the correct way to load the cord and the correct cord diameter.
Keep the teeth of the blade correctly sharpened! Follow our recommendations. Also refer to the instructions on the blade packaging.
Maintain the correct blade setting! Follow our instructions and use the recommended file gauge.
WARNING! Always stop the engine before doing any work on the cutting attachment.
!
This continues to rotate even after the throttle has been released. Ensure that the cutting attachment has stopped completely and disconnect the HT lead from the spark plug before you start to work on it.
WARNING! Using an incorrect cutting attachment or an incorrectly sharpened
!
blade increases the risk of blade thrust.
General rules
Only use cutting attachments with the guards we recommend! See the chapter on Technical data.
Keep the teeth of the blade correctly sharpened! Follow our instructions and use the recommended file gauge. An incorrectly sharpened or damaged blade increases the risk of accidents.
Keep the correct setting on the saw blade! Follow our instructions and use the recommended setting tool. An incorrectly set saw blade increases the risk of jamming and blade thrust, and damage to the saw blade.
Check the cutting attachment for damage or cracks. A damaged cutting attachment should always be replaced.

Cutting equipment

Saw blades are intended for cutting fibrous types of wood.
Grass blades and grass cutters are intended for cutting coarse grass.
A trimmer head is intended for trimming grass.

Sharpening grass cutters and grass blades

See the cutting attachment packaging for correct sharpening instructions. Sharpen blades and cutters using a single-cut flat file.
Sharpen all edges equally to maintain the balance of the blade.
WARNING! Always discard a blade that is bent, twisted, cracked, broken or damaged
!
in any other way. Never attempt to straighten a twisted blade so that it can be reused. Only use original blades of the specified type.
10 – English
SAFETY INSTRUCTIONS

Sharpening the saw blade

See the cutting attachment packaging for correct sharpening instructions.
A correctly sharpened blade is essential for working efficiently and to avoid unnecessary wear to the blade and clearing saw.
Make sure that the blade is well supported when you file it. Use a 5.5 mm round file with a file holder.
The filing angle is 15°. File alternate teeth to the right and those in between to the left. If the blade has been heavily pitted by stones it may be necessary to dress the top edges of the teeth with a flat file, in exceptional cases. If so, this should be done before filing with a round file. The top edges must be filed down by the same amount for all the teeth.

Trimmer head

IMPORTANT!
Always ensure the trimmer cord is wound tightly and evenly around the drum, otherwise the machine will generate harmful vibration.
Only use the recommended trimmer heads and trimmer cords. These have been tested by the manufacturer to suit a particular engine size. This is especially important when a fully automatic trimmer head is used. Only use the recommended cutting attachment. See the chapter on Technical data.
Smaller machines generally require small trimmer heads and vice versa. This is because when clearing using a cord the engine must throw out the cord radially from the trimmer head and overcome the resistance of the grass being cleared.
The length of the cord is also important. A longer cord requires greater engine power than a shorter cord of the same diameter.
Make sure that the cutter on the trimmer guard is intact. This is used to cut the cord to the correct length.
To increase the life of the cord it can be soaked in water for a couple of days. This will make the line tougher so that it lasts longer.
Adjust the blade setting. This should be 1 mm.
