Turn the machine off remember that ALL parts of the user manual are important, as they are included to help prevent injury to the user and damage to the machine. Following correct manual procedure does not necessarily prevent all danger risk, but certainly reduces the probability or effects of injury or damage.

Manual layout: Section B is divided into various

parts that are referred to in the rest of the manual and marked with the “Warning” sign, followed by the

reference number of the corresponding component to draw the reader’s attention to the main safety procedure linked with that particular situation; the machine parts shown in “A – GENERAL

DESCRIPTION” are indicated in italics in the text for easy identification.

Precautions prior to machine use. Never permit

this machine to be used by any persons who are not perfectly familiar with the manual instructions, who are not in good physical and mental condition, who are not sufficiently competent and by children (local regulations may sometimes limit the age of operators permitted to use the machine). Inexperienced persons must follow a training period operating on a saw horse only. The user is responsible for any accidents that may cause injury to other persons and damage to property, as well as any other type of danger risk. The machine must never be used for operations other than those specifically described in this manual, and exclusively with the bars and chains indicated. This machine must never be used when users are tired, or not in good physical condition, or if under the effect of any substance that may alter their physical or mental condition (pharmaceuticals, alcohol, drugs etc.) Make certain that the user knows how to stop the motor and chain in case of necessity.

Take great care and pay close attention at all times when using this machine, following all general behaviour rules according to good sense.

1. Control checks. Control the machine with care

before use each time, especially if it has been subject to strong impact, or if it shows any signs of malfunction. Check that the machine has been assembled correctly, that all components are in correct condition and perfectly clean. Perform all operations described in the chapter “Maintenance – before each use”. Make sure that all spanners and tools used for adjustment operations have been removed, that all screws and nuts are in their correct housing and tightened correctly, and that the bar and the chain are mounted correctly. If even one single condition described above is not satisfactory DO NOT

USE the machine.

2. Repairs and Maintenance. All the machine parts

that can be replaced personally, are clearly explained in the “Assembly / disassembly” instructions chapter.

In the case of damaged or worn components, always use exclusively original homologated accessories and spare parts that are available from official distributors.

Where necessary, all other machine parts must be replaced exclusively by an Authorised Service

Centre. All danger risks increase considerably if maintenance operations are not performed regularly, not performed by competent professional personnel, or if non-original accessories /spare parts are mounted on the machine. In any of the cases described above, the manufacturer will not be held responsible for any injury to persons or damage to property. In the case of any doubt, please contact an

Authorised Service Centre.

3. Maintenance in complete safety. All

maintenance, assembly, disassembly and oil tank filling operations must be performed with the machine set in a stable position on a flat solid surface and with the cable plug disconnected from the electricity supply (unless this is explicitly specified otherwise).

The chain must be arrested and the user must wear suitable protective gloves.

4. Clothing. When using this machine the user must

wear the following homologated individual protective clothing : close-fitting protective clothing, safety boots with non-slip soles, crush-proof toe puffs and cutproof protection; cut-proof vibration-proof gloves, protective goggles or safety visor (remove protective film where present); ear protection muffs; helmet (if there is any danger of falling objects); some efficient method to cover or tie hair back from shoulder length

(if hair is longer than shoulders); dust-proof mask. DO

NOT WEAR shorts, loose clothing, unbuttoned clothing, or any jewellery that could become caught in moving machine parts. Do not wear sandals and never work bare-footed.

5. Health precautions – Vibrations and Noise

levels. Avoid using the machine for long periods of

time: the noise and vibrations can be dangerous causing irritation, stress, fatigue and hypacusia

(hearing problems). Prolonged machine use exposes the user to vibrations that can generate “white finger phenomenon” (Raynaud’s Phenomenon), carpal tunnel syndrome and similar disturbances. This can lead to a lack of sensitivity in the hands making it difficult to notice changes in temperature as well as causing numbness. When using the machine regularly or in continuation, the user must control the condition of his hands very carefully. If any of the symptoms described above appear, consult a doctor immediately.


6. Health precautions – Chemical agents. Avoid all

chain oil contact with skin and eyes.

7. Health precautions - Electricity. All extension

cords, plugs, and electricity lines must be homologated, to standard and in compliance with current regulations. Make sure that the main line to which the machine is connected is equipped with a residual current device (RCD) with a current capacity no higher than 30mA. Make sure that all cables, plugs, and the residual current device are in correct working condition, that they comply with required characteristics, are mounted or hooked up correctly and are perfectly clean. Never disconnect the machine from the main line by pulling on the cable.

Never use or store the machine and extension cord in damp environments. If the cable is damaged in any way, disconnect immediately from the main line socket, taking great care not to touch any exposed wires. Avoid all contact with grounded surfaces when using the machine (metal piping, cables, lightening conductors, etc). When working outdoors, all extension cords attached to the machine must be homologated for use out of doors. Avoid tying any knots in electric cables and never use rolled up extension cords.


Health precautions

- Heat. During use pinion

and chain reach very high temperatures, take care not to touch these parts while hot.


Health precautions

– Sharp or moving

parts. Never touch the chain except when the

machine is switched off; in any case, always take great care since the chain is very sharp and can cut even when stopped. Remember that the chain will continue to rotate for a short time after the machine has been switched off.

10. Work area. Control the whole work area carefully

to check for any danger source (e.g.: roads, paths, electric cables, dangerous trees, etc) Take special care when working on sloping ground. Cluttered areas can lead to injuries: before using the machine remove any stones, glass, cables, metal components, cans, bottles and any other foreign matter from the work area. Also take into consideration any danger risks that may not be noticed because of machine noise. Make sure that a second person is within calling distance in the case of accident. When working in isolated areas, always carry a first aid kit and make sure you have advised others of your exact location.


11. Work operations

Never start work with the machine before

performing the following: remove the giude bar

cover guard; make sure that a sufficient amount of oil has reached the chain; make sure you have a planned retreat path from falling trees (when cutting trees).

It is strictly forbidden to use the machine for:

moving branches or roots; in cases where there is any danger that the chain may come into contact with the ground, electric protection, or piled wood; for cutting very thin branches or bushes (these will break easily and can whip bystanders or the user causing serious injury); for felling trees without adequate training and equipment (correct ropes, hooks, etc); starting sawing operations with the blade already engaged in a previous groove or slit; using the machine while standing on stepladders or other unstable surfaces; using the machine in extreme weather conditions, inclement weather, with reduced visibility and insufficient lighting (very low temperatures, very hot damp climates, fog, rain, wind, at night, etc.); using the machine with arms stretched: work must always be performed in a manner to ensure that the user can react immediately to unexpected conditions; it is forbidden to leave the machine unguarded; permitting others to touch the cable, extension cord , or the machine; forcing the machine during cutting action (this can lead to motor damage or loss of control over the machine); blocking the switch or the switch block with adhesive tape or other materials.

Always remember to: cut wood only (never cut

plastic, metal, or other materials); make sure that the

switch is NOT turned ON before inserting the plug in the socket or releasing the chain brake lever; make sure that the chain is not in contact with any objects at the moment the switch is turned ON; Keep all bystanders and animals well clear of the work area

(where necessary, fence off the area and use warning signs) at a minimum distance of 2.5 m times the trunk height; in any case no less than ten meters.

Wherever possible use a vice or a saw horse to block the wood to be cut; always hold the machine as follows: Grip the front handle with the left hand and the rear handle with the right hand, closing the thumb and other fingers firmly around the handle (during use, the machine could slide forwards or backwards, or create a reverse action, provoking a kickback reaction: holding the machine correctly reduces the risk of loosing control over the tool); Always make

sure that the cable/ extension cord is kept behind the user, controlling that it does not create a source of danger for the user or for other persons, and check that it cannot be damaged (by heat, sharp objects, sharp edges, oil, etc); Always assume a stable standing position on both legs; keep the handles dry and clean; during use keep all body parts and clothing well clear of the chain; turn off the switch, wait until the chain has stopped turning, and activate the chain brake lever before putting down the saw; never attempt to cut at heights over shoulder height; always handle the machine with the utmost care; check that the oil level never drops below MIN level, controlling frequently, before and during use; Always remain on the left hand side of the machine during use, and take great care if the bar needs to be inserted in a previously cut slit; remove the bar from the slit when the chain is still in rotation.

12. Transport and storage precautions. Each time

the work area is changed to another location, disconnect the machine from the main line and activate the chain brake lever. Mount the guide bar

cover guard each time before transporting or storage.

Always carry the machine by hand with the bar facing backwards, or when transporting the machine in a vehicle, always attach it securely to prevent damage.

Never carry the machine by the cable. After use, store the machine in a dry, high place, far from heat sources and out of reach of children.

13. Precautions against fire risk. Never use the

machine in areas where there are naked flames, inflammable or potentially explosive materials.

14. Kickback reaction. The kickback reaction

consists of a violent upwards-reverse action of the

bar towards the user. This generally occurs if the upper part of the bar nose (called the “kickback danger zone”) comes into contact with some object, or if the chain is blocked in the wood. The kickback reaction is a very quick sudden motion along the bar cutting plane (generally in an upward direction, but this also depends on the machine position during cutting action). Kickback can make the user loose control of the machine provoking dangerous and even mortal accidents (i.e: if the saw with the chain in rotation is thrust back against the user). The chain

brake lever and other safety devices are not sufficient to protect the user against injury: the user must be well aware of the conditions that can provoke the reaction, and prevent them by paying very close attention according to experience, together with prudent and correct machine handling (for example: never cut several branches at a time because this can cause accidental impact on the “kickback danger zone”; never mount incorrect bars or chains; make sure the chain is always sharp and sharpen according to correct methods, because incorrect sharpening can cause kickback; when choosing the

bar, remember that the smaller the nose radius, the smaller the kickback danger zone).



Your machine is equipped with a device (fig.1) that when deactivated, stops the switch from being pressed thus preventing accidental start-up.


(for ES18 models only)

Your machine is equipped with a device that blocks the chain immediately as soon as the switch is released; If this device should not work at any time, the machine must NOT be used, and must be taken to an Authorised Service Centre.


The front hand guard (fig.2) is designed to prevent your left hand from coming into contact with the chain

(on condition that the machine is held correctly according to instructions) . The front hand guard also acts as a chain brake, including a device that blocks the chain in a few fractions of a second in the case of kickback. The chain brake is released when the front

hand guard is pulled backwards and blocked in position (the chain is able to move). The chain brake is activated when the front hand guard is pushed forward (the chain is blocked).


The chain brake can be activated in two modes: the first using the left wrist by pushing forwards, or when it comes into contact with the brake system as a result of kickback; or by inertia, in the case of particularly violent kickback.

When the machine is used with the bar in horizontal position, for example during tree felling, the chain

brake offers less protection, because it can be activated by inertia only, since the user’s hand is outside the range of action of the front hand guard


N.B.: When the chain brake is activated, a safety switch cuts off all current to the motor.


This machine is equipped with a chain catcher (fig.4) located under the pinion. This mechanism is designed to arrest the backward chain movement in the case of chain breaking or derailing. These situations can be avoided by ensuring correct chain tension (Refer to chapter “D. Assembly/disassembly”).


This acts to protect(fig.5) the hand in the case of

chain breaking or derailing.

D. ASSEMBLY / DISASSEMBLY 2,3,6,7,8,9,12


Assembly methods change according to the type of your machine- so please take care to refer to the illustrations and machine type marked on the label (A- Legend – 9 [ES15 / ES16 / ES18] ), Take great care when assembling to ensure this is performed correctly.

FOR ES 15 / ES 16 FOR ES 18


Control that the chain brake is not activated. If so, deactivate it.


Unscrew the bar retaining nuts and remove the chain cover.


Unscrew the bar retaining knob and remove the

chain cover.


Mount the bar on the bar retaining screws

pushing it as far backward towards the pinion as possible.


Mount the bar on the bar retaining screw pushing it as far backward towards the pinion as possible.


Oil the chain, then position it over the pinion, making it slide into the bar guide groove, beginning with the upper part. Attention! Control that the sharp side of the cutting teeth face in a frontward direction on the upper part of the bar; Set the chain tensioner pin in the chain tensioner pin housing. Mount the chain

cover making sure that the drive teeth of the chain are engaged in the pinion and in the guide groove.


Close the bar retaining nuts, screwing by hand.


Screw the bar retaining knob loosely tightened.


To spread the chain screw the chain

tensioner screws in a clockwise direction, to loosen tension, screw in an anti-clockwise direction (when performing this operation maintain the bar nose raised upwards)


To spread the chain screw the chain tensioner

knob in a clockwise direction, to loosen tension, screw in an anti-clockwise direction (when performing this operation maintain the bar nose raised upwards)


Spread the chain until the tension is correct; that is, when the chain is pulled upwards, the drive tooth rise to the same level as the bar. (the chain must never droop on the underside of the bar)


Tighten the bar retaining nuts using an appropriate tool.


Tighten the bar retaining knob strongly.

Tensioning the chain too tightly will overload the motor and cause damage, insufficient tension can provoke chain derailing, whereas a chain tightened correctly provides the best cutting characteristics and prolonged work life. Check the tension regularly because the chain length tends to stretch with use (especially when the chain is new; after the first assembly, the chain tension must be controlled after 5 minutes machine operation); in any


case do not tighten the chain immediately after use, but wait until it cools down.

In cases where the loosened chain needs to be adjusted, always unscrew the bar retaining nuts / knob before adjusting the chain tensioning screw/knob ; adjust the tension and tighten the bar retaining nuts /knob accordingly.

E. START-UP AND ARREST 1,4,5,6,7,8,9,11,12,13

Start-up: grip both handles firmly, release the chain

brake lever, press and maintain the switch block pressed in, then press the switch (at this point the

switch block can be released).

Arrest: The machine will stop whenever the switch is

released. In the case where the machine does not stop, activate the chain brake, disconnect the cable from the main line socket and take the machine to the

Authorised Service Centre.


ATTENTION! Insufficient lubrication will provoke

chain breaking and can cause serious and even mortal injury.

Bar and chain lubrication is performed by an automatic pump. If your machine is equipped with an

oil pump adjustment knob (optional) the chain lubrication can be adjusted as shown in the illustration (fig.1), according to the type of cutting operation in hand (dry wood – more oil, green wood - less oil, long bar- more oil, short bar - less oil).

Take great care to ensure that the chain is always sufficiently lubricated by never closing the pump completely. Refer to “Maintenance” for indications on ensuring that the chain oil is sufficiently distributed.

Choice of chain oil

Always use new oil only (special type for chains) with adequate viscosity: the oil must adhere well and guarantee good running properties in both winter and summer. If chain oil is not available, EP 90 transmission oil can be used.

Never use waste oil because this is this harmful to health, the machine and the environment. Make sure that the oil is suitable for the temperature of the environment where the tool will be used: For temperatures under 0°C certain oils become denser, overloading the pump and causing damage. Contact your Authorised Service

Centre for advice on oil choice.

Filling oil tank

Unscrew the oil tank cap, and fill the tank taking care not to spill any oil (if this occurs clean the machine carefully) (fig.2), and then screw the cap back on tightly.

Before each use

Control that the chain oil pump functions correctly: direct the bar towards a clear surface at a distance of about 20 centimetres; after the machine has run for about a minute, the surface should show clear traces of oil(fig.1).

G. MAINTENANCE 1,2,3,4,5,6,7,8,9,12,13

ATTENTION! In cases where work environments are

particularly dirty or dusty, the operations described must be performed more frequently than mentioned in the instructions.

Check that excessive strength is not needed for activating and deactivating the chain brake. Also check that it is not activated too easily and that it is not blocked. Then check chain brake function as follows: release the chain brake, grip the machine correctly and start up the machine, activate the chain brake by pushing the front hand guard forward with the left wrist or arm but without removing the hand from the handle(fig.2). If the chain brake is working correctly, the chain should be blocked immediately.


Check that the chain is sharpened correctly (See below), in good working condition and that the tension is correct. If the chain is irregularly worn, or if the cutting teeth are only 3 mm high, the chain must be replaced(fig.3).

Clean the air vents regularly to prevent motor overheating.

Check that the switch and switch block function correctly (to be performed with the chain brake released): press the switch and the switch block and control that they return to idle position as soon as they are released; control that it is impossible to press the switch without activating the switch block.

Check that the chain catcher and the right hand

guard are in correct condition without any visible faults such as damaged material.

Every 2-3 hours of use

Control the bar condition, if necessary clean the

lubrication holes(fig.4) and the guide grooves(fig.5) carefully; If the groove is worn or shows signs of deep notching, it must be replaced. Turn the bar to ensure even wear(fig.6). Clean the pinion regularly and check that it has not been subject to excess wear(fig.7).

Lubricate the nose sprocket with bearing grease through the hole shown in the illustration (fig.8).

Chain sharpening (When necessary)

If the chain does not cut correctly, or requires hard

bar pressure against the wood, and if the sawdust is very fine, this is a sign that it is not sharpened correctly. If the cutting action produces no sawdust, this means the cutting edge has been worn completely and the chain is pulverising the wood during cutting. A well-sharpened chain crosses through the wood without effort or pressure and produces large long wood shavings.

The cutting side of the chain is composed of the cutting

link (fig.9) with a cutting tooth(fig.10) and a cutting limit

gauge(fig.11). The difference between these determines the cutting depth; a file guide and a 4mm diameter round file are needed to obtain good sharpening results; Follow the instructions below: Once the chain has been mounted and the tension is correctly adjusted, and the

chain brake is activated, position the file guide perpendicular to the bar as shown in the illustration(fig.12), filing the cutting teeth at the angle shown(fig.13), always working from the interior towards the exterior, lessening the pressure during the return stage (it is very important to follow the instructions perfectly: excessive or insufficient sharpening angles, or an incorrect file diameter will increase the risk of kickback.) To obtain higher precision on side angles, it is advisable to position the file so that it exceeds the upper cutter by about 0.5 mm. File all the teeth on one side first, then turn the machine over and repeat the operation.

Make sure that after sharpening operations, all teeth are the same length and that the height of the depth gauge is

0.6 mm lower than the upper cutter: check the height using a proper template and file (with a flat file) all protruding parts, rounding off the front part of the depth

gauge(fig.14), paying attention to not file the kickback

protection tooth(fig.15)

Every 30 hours use.

Take the machine to the Authorised Service Centre for general revision and control check on brake components.


Always empty the fuel tank with the same precautions used in filling it.

H. CUTTING TECHNIQUES 1,2,3,4,5,6,7,8,9,10,11,12,13,14

When using the machine, prevent: (fig.1)

- cutting in conditions where the trunk could split during cutting (wood under pressure, dry dead trees, etc): sudden splitting can be very dangerous.

- the bar or the chain from becoming blocked in the cutting notch: if this should occur, disconnect the machine from the main electricity supply and try to raise the trunk using an appropriate tool as a lever; do not attempt to free the machine by shaking or pulling as this could cause damage or injury.

- situations that can lead to kickback reactions.

During machine use: (fig.1)

- When cutting on sloping ground, always work uphill of the trunk to avoid being hit if the trunk should roll downhill.

- Release the switch after each cutting action: prolonged dry running of the motor will provoke serious damage.

- When felling trees, always finish the job: a partially cut tree could break and fall.


- At the end of each cutting operation the user will notice a considerable change in the strength necessary for controlling the machine. Great care must be taken not to loose control .

Below is a description of two different types of cutting operation:

Cutting action by pulling the chain (from top to bottom) (fig.2) can lead to dangerous sudden movement of the machine towards the trunk with consequential loss of control. Where possible, use the spiked bumper during cutting operations.

Cutting action pushing the chain (from bottom to top)

(fig.3) will lead to the danger of a sudden movement of the machine in the direction of the user, with the risk of hitting the user, or an impact of the “kickback danger zone” on the trunk resulting in strong kickback; extreme care must be taken when cutting in this manner.

The safest method for using the machine, is to block the log on a sawhorse, cutting from top to bottom, on the portion outside the sawhorse. (fig.4)

Spiked bumper use.

Where possible, use the spiked bumper to ensure safer cutting action: plant it in the bark or surface of the trunk in order to maintain more control over the machine.

Below are descriptions of typical cutting procedure to be adopted for specific situations. However, these should be assessed each time to calculate whether the method is most suitable or not, in order to use a method with the least possible risk.

Trunk on the ground. (Risk of touching the ground

with the chain once the bar has passed trough the trunk). (fig.5)

Cut from top to bottom through the whole trunk.

Towards the end of the cut, proceed very carefully to prevent the chain from hitting the ground. If it is possible, cut 2/3 of the trunk, roll it over, and cut the remaining third from top to bottom to limit the risk of the chain touching the ground.

Trunk supported at one end only (Risk of trunk

breaking during cutting action). (fig.6)

Begin the cut from underneath for about 1/3 of the diameter, and then finish the cutting action from the top to meet the undercut.

Trunk supported at both ends. (Risk of pinching the

chain). (fig.7)

Begin the cut from above for about 1/3 of the diameter, and then continue from underneath to meet the overcut.

Tree felling.

ATTENTION! : Never attempt to fell a tree if you do not have the necessary experience, and in any case never fell trees that have trunks with a diameter larger than the length of the bar ! This operation is reserved for expert machine users with adequate equipment.

When felling a tree, the aim is to have the tree fall in the most convenient position for the following limbing and bucking operations. (Avoid trees falling on top of other trees: Felling trees that are entangled with other trees is a very dangerous operation).

First of all decide which is the best direction for the tree to fall by evaluating the following: objects or other plants around the tree, the inclination, the curve, wind direction, and greatest branch concentration. Take into account dead or broken branches that may break off during felling creating a further danger risk.

ATTENTION! During tree felling operations in critical

conditions, always remove ear protection immediately after cutting operations to be able to listen for unusual noises and any warning signals.

Preliminary cutting operations and identifying the retreat path.

Eliminate any branches that interfere with the job

(fig.8), starting from top to bottom, and then, always keeping the trunk between the user and the machine eliminate the more difficult branches afterwards, piece by piece. Eliminate all plants that interfere with work operations and control the area for possible obstacles

(rocks, roots, ditches,etc.) when planning the retreat path (to follow during tree fall); Refer to the illustration

(fig.9) for the directions to be maintained (A. predicted tree fall direction. B. Retreat path. C. Danger zone).


In order to ensure that the user has complete control over the tree fall, the cutting instructions are as follows:

The cut that controls the fall direction of the tree is to be executed first: First of all cut the UPPER PART of the directional notch on the side the tree must fall.

Remain on the right hand side of the tree and cut using the chain pull method; then cut the LOWER

PART that must meet the end of the upper part. The depth of the directional notch must be ¼ of the trunk diameter, with an angle of at least 45° between upper


and lower cut. The meeting point between the two sides of the notch is called “directional cut line” This line must be perfectly horizontal at right angles (90°) to the felling direction.

The felling cut that provokes the tree fall, is performed at 3 to 5 cm above the lower part of the directional felling cut line, finishing at a distance of 1/10 of the trunk from the notch. Remain on the left hand side of the tree and cut using the chain pulling method and the spiked bumper. Check that the tree does not move in a direction other than that predicted for the fall. As soon as possible insert a felling lever or wedge into the cut. The uncut part of the trunk is called the “hinge”, as it is intended to guide the tree as it falls; in cases where the cuts are not sufficient, not straight, or have been cut through completely, the tree fall cannot be controlled (extremely dangerous!).

For this reason the various cuts must be performed with great precision.

When cutting operations are completed the tree will begin to fall. Where necessary help tree fall using wedges or felling levers



Once the tree has been felled, the trunk must be limbed: in other words, the branches are removed from the trunk. Do not underestimate this operation because the large majority of kickback accidents occur during this stage. For this reason pay close attention to the position of the bar nose during cutting operations and always work on the left hand side of the trunk.


This section contains information useful for maintaining the characteristic of ecocompatibility included in the origin design of the machine, and as regards proper use and disposal of chain oil


In the design stage, care was taken to develop an engine with reduced consumption and low emission of noise.


The operations of filling the oil tank should be carried out in such a way as to avoid spilling oil and contaminating the soil and the environment.


Do not dispose inappropriately of the machine when it is no longer usable. Deliver it to an authorized organization for proper disposal in compliance with the regulation in force.
