WARNING: Once the engine is warmed
up do not use the choke to start up again.
WARNING: Use the semi-acceleration device only in the phase of starting the engine to cold.
BREAKING-IN THE ENGINE
The engine reaches the maximum power after 5÷8 hours of activity. During this period of breaking-in do not use the engine at wide open throttle without load, to avoid excessive functioning stress.
STARTUP PROCEDURE
1) Slowly push the purge bulb 4 times (9, Fig.1).
28
WARNING! - During the breaking-in period do not vary the carburetion to obtain a
presumed power increment; the engine can be damaged.
NOTE: It is normal for smoke to be emitted from a new engine during and after first use.
6. STOPPING THE ENGINE
Set the throttle lever to idle position (18, Fig. 1) and wait a few seconds to let the engine cool o. Turn o the engine, pushing the ON/OFF switch (17).
7. USING THE MACHINE
PROHIBITED USE
WARNING: Avoid kickout which can result in serious injury. Kickout is the sideward or sudden forward motion of the machine occurring when the blade contacts any object such as a log or stone, or when the wood closes in and pinches the saw blade in the cut. Contacting a foreign object can also result in loss of brush cutter control.
WARNING! - Always follow the safety precautions. The brush cutter must only be used to trim grass material. Cut wood only with appropriate saw blade. Do not cut metal, plastics, masonry, or non-wood building materials. Do not use the brush cutter as a lever to lift, move or break objects, nor lock it on xed supports. It is forbidden to apply tools or applications that are not the ones indicated by the manufacturer onto the brush cutter’s power take-o.
WARNING: When using rigid blades, avoid cutting close to fences, sides of buildings, tree trunks, stones or other such objects that could cause the brush cutter to kick out or could cause damage to the blade. We recommends use of the nylon line heads for such jobs. In addition, be alert to an increased possibility of ricochets in such situations.
Never use the brushcutter for trimming hedges.
WARNING: If the blade loosens after being properly tightened, stop work immediately. The retaining nut may be worn or damaged and should be replaced. Never use unauthorized parts to secure the blade. If the blade continues to loosen, see your dealer. Never use the brushcutter for trimming hedges.
Work Area Precautions
• Always cut with both feet on solid ground to
prevent being pulled off balance.
• Make 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.
• Do not cut above chest height, as a brush
cutter held higher is difficult to control against kickout forces.
• Do not work near electrical wires. Leave this
operation for professionals.
• Cut only when visibility and light are adequate
for you to see clearly.
• Do not cut from a ladder, this is extremely
dangerous.
• Stop the brush cutter if the blade strikes a
foreign object. Inspect the blade and brush cutter; repair parts as necessary.
• Keep the blade out of dirt and sand. Even a
small amount of dirt will quickly dull a blade and increase the possibility of kickout.
• Stop the engine before setting the brush
cutter down.
• Be particularly cautious and alert while
wearing hearing protection because such equipment may restrict your ability to hear sounds indicating danger (calls, signals, warnings, etc).
• Be extremely cautious when working on
slopes or uneven ground.
GB
WARNING: Never use of a brush cutter above ground level or with the cutting attachment perpendicular to the ground.
WARNING: Never use rigid blades when cutting in stony areas. Thrown objects or damaged blades may result in serious or fatal
29
injury to the operator or bystanders. Watch out for thrown objects. Always wear approved eye protection. Never lean over the cutting
GB
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.
obstacles (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.
5. Never put the machine down with the engine running.
• Always use the correct equipment.
• Make sure the equipment is well adjusted.
• Organise your work carefully.
• Always use full throttle when starting to cut with the blade.
• Always use sharp blades.
Working Techniques General Working Instructions
WARNING: 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.
come into contact with the cutting attachment or loose objects that are thrown out by the cutting attachment.
WARNING: 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, etc.
3. Make sure you can move and stand safely.
Check the area around you for possible
30
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 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: Sometimes branches or grass get caught between the guard and cutting attachment. Always stop the engine before cleaning.
Check before starting
• Check the blade to ensure that no cracks have
formed at the bottom of the teeth or by the centre hole. Discard a blade if cracks are found.
• Check that the support flange is not cracked
due to fatigue or due to being tightened too much. Discard the support flange if it is cracked.
• Ensure the locking nut has not lost its captive
force. The tightening torque of the locking nut should be 25 Nm.
• Check that the blade guard is not damaged or
cracked. Replace the blade guard if it is cracked.
WARNING: Never use the machine
without a guard or with a defective guard. Never use the machine without the transmission shaft.
Forestry clearing
• 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.
• Work systematically to and fro across the area, clearing a width of around 4-5 m on each pass. This exploits the full reach of the machine in both directions and gives the operator a convenient and varied working area to work in.
• Clear a strip around 75 m long. Move your fuel can as work progresses.
• On sloping ground you should work along the slope. It is much easier to work along a slope than it is to work up and down it.
• You should plan the strip so that you avoid going over ditches or other obstacles on the ground. You should also orient the strip to take advantage of wind conditions, so that cleared stems fall in the cleared area of the stand.
Grass clearing using a grass blade
• Grass blades and grass cutters must not be used on woody stems.
• The grass is cut down with a sideways, swinging movement, where the movement from right-to-left is the clearing stroke and the movement from left-to-right is the return stroke. Let the left-hand side of the blade (between 8 and 12 o’clock) do the cutting.
• If the blade is angled to the left when clearing grass, the grass will collect in a line, which makes it easier to collect, e.g. by raking.
• Try to work rhythmically. Stand firmly with your feet apart. Move forward after the return stroke and stand firmly again.
• Let the support cup rest lightly against the ground. It is used to protect the blade from hitting the ground.
• Reduce the risk of material wrapping around the blade by following these instructions:
1. Always work at full throttle.
2. Avoid the previously cut material during the return stroke.
• Stop the engine, unclip the harness and place the machine on the ground before you start to collect the cut material.
Grass trimming with a trimmer head
CAUTION: Do not work with mowing line longer than the intended diameter. With a properly mounted guard, the built-in cutter will automatically adjust the line to its proper length. Overly long lines can overload the engine, resulting in damage to the clutch mechanism and nearby parts.
Trimming
• Hold the trimmer head just above the ground
at an angle. It is the end of the cord that does the work. Let the cord work at its own pace. Never press the cord into the area to be cut.
• The cord can easily remove grass and weeds
up against walls, fences, trees and borders, however it can also damage sensitive bark on trees and bushes, and damage fence posts.
• Reduce the risk of damaging plants by
shortening the cord to 10-12 cm and reducing the engine speed.
Clearing
• The clearing technique removes all unwanted
vegetation. Keep the trimmer head just above the ground and tilt it. Let the end of the cord strike the ground around trees, posts, statues and the like.
CAUTION: This technique increases the wear on the cord.
• The cord wears quicker and must be fed
forward more often when working against stones, brick, concrete, metal fences, etc., than when coming into contact with trees and wooden fences.
• When trimming and clearing you should use
less than full throttle so that the cord lasts
GB
31
longer and to reduce the wear on the trimmer head.
GB
Cutting
• The trimmer is ideal for cutting grass that is difficult to reach using a normal lawn mower. Keep the cord parallel to the ground when cutting. Avoid pressing the trimmer head against the ground as this can ruin the lawn and damage the tool.
• Do not allow the trimmer head to constantly come into contact with the ground during normal cutting. Constant contact of this type can cause damage and wear to the trimmer head.
Sweeping
• The fan effect of the rotating cord can be used for quick and easy clearing up. Hold the cord parallel to and above the area to be swept and move the tool to and fro.
WARNING: Never cut, when visibility is poor or in very high or low temperatures or in freezing weather.
Forestry clearing using a saw blade
• The risk of kickout increases with increasing
stem size. You should therefore avoid cutting with the area of the blade between 12 o’clock and 3 o’clock (Fig.16).
• To fell to the left, the bottom of the tree should
be pushed to the right. Tilt the blade and bring it diagonally down to the right, exerting firm pressure. At the same time push the stem using the blade guard. Cut with the area of the blade between 3 o’clock and 5 o’clock. Apply full throttle before advancing the blade.
• To fell to the right, the bottom of the tree
should be pushed to the left. Tilt the blade and bring it diagonally up to the right. Cut with the area of the blade between 3 o’clock and 5 o’clock so that the direction of rotation of the blade pushes the bottom of the tree to the left.
• To fell a tree forwards, the bottom of the tree
should be pulled backwards. Pull the blade backwards with a quick, firm movement.
• If the stems are tightly packed, adapt your
walking pace to suit.
• If the blade jams in a stem, never jerk the machine free. If you do this the blade, bevel gear, shaft or handlebar may be damaged. Release the handles, grip the shaft with both hands and gently pull the machine free.
Using the circular saw blade
WARNING: Circular saw blades are suitable for thinning brush and cutting small trees up to a diameter of 5 cm. Do not attempt to cut trees with larger diameters, since the blade may catch or jerk the clearing saw forward. This may cause damage to the blade or loss of control of the clearing saw which may result in serious injury.
WARNING: A saw blade can only be used in connection with the proper guard (see table pag.38) a twin handle and double harness with release mechanism.
Brush cutting with a saw blade
• Thin stems and brush are mown down. Work with a sawing movement, swinging sideways.
• Try to cut several stems in a single sawing movement.
• With groups of hardwood stems, first clear around the group. Start by cutting the stems high up around the outside of the group to avoid jamming. Then cut the stems to the required height. Now try to reach in with the blade and cut from the centre of the group. If it is still difficult to gain access, cut the stems high up and let them fall. This will reduce the risk of jamming.

BLADE SHARPENING 234 TOOTH
1. Blades are reversible: when one side is no
GB
longer sharp, the blade can be turned over and used on the other side (Fig. 17).
2. Blades are sharpened using a at single-cut le (Fig. 17).
3. To maintain the correct balance, le all cutting edges uniformly.
4. If the blades are not sharpened correctly, this can set up abnormal vibrations in the machine and cause the blades themselves to break ultimately.
BLADE SHARPENING (8 TOOTH
Always check the general condition of the blade. Correct sharpening permits the maximum performance of the brush cutter. To sharpen the teeth, use a le or grindstone and proceed with light touches, respecting the corners and the dimensions shown in Fig. 11.
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.
• 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.
WARNING! – The wrong type of cutter or
WARNING: Never repair damaged cutting attachments by welding, straightening or modifying the shape. This may cause parts of the cutting tool to come off and result in serious or fatal injuries.
NYLON LINE HEAD
Replacing the nylon line on the LOAD&GO trimmer head (Fig.19)
1. Cut 6.0 m of nylon line Ø 3.0 mm.
2. Align the arrows and insert the line into the trimmer head (Fig. 19.1) until it is released from the opposite side (Fig.19.2).
3. Divide the line into two equal parts (Fig. 19.3) and then load the trimmer head by turning the knob (Fig. 19.4).
WARNING! – Always wear protective gloves during maintenance operations. Do not carry out maintenance with the engine hot.
AIR FILTER
Every 8-10 working hours, remove the cover (A, Fig. 22), clean the lter (B). Blow with compressed air, at a distance. Replace if dirty or damaged. The engine runs irregularly if the lter is clogged, with consequent higher consumption and lower performance.
FUEL TANK
Check fuel lter periodically. A dirty lter can cause dicult starting and lower engine performance. To clean lter proceed as follows: remove it from fuel lling hole. Replace it (Fig. 21) if too dirty.
ENGINE
Clean cylinder ns with a brush or compressed air periodically. Dangerous overheating of engine may occur due to impurities on the cylinder.
SPARK PLUG
Clean spark plug and check electrode distance periodically (Fig. 23). Use Champion NGK BPMR7A or of other brand with the same thermal grade.
GEAR HOUSING
Every 30 working hours, remove screw (D, Fig. 8)
34
on the gear housing and check the quantity of grease. Do not use more than 10 grams. Use high quality molybdenum bisulde grease.
Never use fuel for cleaning operations.
CARBURETOR
Before adjusting the carburetor, clean the air lter (B, Fig. 22) and warm up the engine. This engine is designed and manufactured in order to comply with the applicable 97/68/EC, 2002/88/EC and 2004/26/EC Directive. The carburetor (Fig. 20)
is designed to permit only the adjustement of L and H screws in a range of 1/4; the quarter
round the hall range admissible for L and H ± 1/8 screws is determined by the manufacturer and you can not modify it.
WARNING: Don’t try to force the screws
outside the range!
Idle screw T is adjusted in order to ensure a good safety margin between idle running and clutch engagement. Screw L must be adjusted so that the engine promptly responds to sharp accelerations and gives good idle operation. Screw H must be adjusted so that the engine gives maximum power during the cutting phase.
WARNING: With the engine idling (2800 rpm), the blade should not rotate. We recommend that you have your nearest authorised dealer or service workshop carry out any carburettor adjustments.
WARNING: Weather conditions and altitude may aect carburation.
MUFFLER
WARNING! - This muer is tted with a
catalytic converter needed for the engine to be in compliance with the emissions requirements. Never modify or remove the catalytic converter: failure to do so is a violation of law.
WARNING! - Muers tted 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 re!
CAUTION! -
must be replaced. If the muffler frequently
becomes blocked, this could be an indication that the efficiency of the catalytic converter is limited.
WARNING: Do not operate your brush cutter if the muffler is damaged, missing or modified. An improperly maintained muffler will increase the risk of fire and hearing loss.
EXTRA MAINTANANCE ADVISABLE
It is advisable to inspect the machine by a specialized technician at an authorized service network at t he e nd of se ason, if us ed intensively, and every two years if with normal use.
ATTENTION: All maintenance operations not reported in this manual must be carried out by an authorized Service Center.
To ensure steady and regular brush cutter operation, remember that parts must only be replaced with ORIGINAL SPARES.
Any unauthorized changes and/or use of non-original replacement parts may result in serious injury or death to the operator or third parties.
10. STORAGE
If the machine is to be stored for long periods:
- Drain and clean the fuel tank in a well-ventilated
area. To drain the tank, start the engine and wait until the fuel is exhausted and the engine stops (leaving fuel mixture in the carburettor could damage the membranes).
- The procedures for returning the machine to
service following winter storage are the same as for starting up during everyday use (page 26).
- Follow all the maintenance regulations
previously described.
- Clean the brush cutter completely and lubricate
the metallic parts.
If the muffler is damaged, it

and lubricate the bevel gear seat.
- Empty the fuel tank and put the cap back on.
- Store the brush cutter in a dry place, preferably not in direct contact with the oor and away from heat sources.
11. ENVIRONMENTAL PROTECTION
Environmental protection should be a priority of conside rable importance when using the machine, for the benefit of both social cohesion and the environment in which we live.
- Try not to cause any disturbance to the surrounding area.
- Scrupulously comply with local regulations and provisions for the disposal of waste materials after mowing.
- Scrupulously comply with local regulations and provisions for the disposal of oils, petrol, batteries, filters, deteriorated parts or any elements which have a strong impact on the environment. T h is wa s te mu s t not be disposed of as normal waste, it must be separated and taken to specified waste disposal centres where the material will be recycled.
Demolition and disposal
When the machine reaches the end of its service life, do not dispose of it into the environment; instead take it to a waste disposal centre. Most materials used in the manufacture of the ma chine are recyclable; all metals (s teel, aluminium, brass) can be delivered to a normal recycling station. For information contact your local waste recycling service. Waste disposal must be carrie d out with respect for the environment, avoiding soil, air and water pollution.
In all cases, applicable local legislation must be complied with.
