SAFETY PRECAUTIONS

Intended use

This power chain saw is only intended for sawing wood outdoors.

General precautions

To ensure correct operation the user has to read this instruction manual to make himself familiar with the characteristics of the chain saw. Users insufficiently informed will endanger themselves as well as others due to improper handling.

It is recommended to lend the chain saw only to people who are experienced in working with chain saws. Always hand over the instruction manual.

First users should ask the dealer for basic instructions to become familiarized with the characteristics of engine powered sawing or even attend a recognized course of instruction.

Children and young persons aged under 18 years must not be allowed to operate the chain saw. Persons over the age of 16 years may, however, use the chain saw for the purpose of being trained as long as they are under the supervision of a qualified trainer.

Operate the chain saw only if you are in good physical condition. If you are tired, your attention will be reduced. Be especially careful at the end of a working day.

Perform all work calmly and carefully. The user has to accept liability for others.

Stay alert, watch what you are doing and use common sense when operating a chain saw. A moment of inattention while operating may result in serious personal injury.

Never use the chain saw after having consumed alcohol, drugs or medication.

The muffler may contain carcinogenic chemicals inside. Avoid contact with them in case the muffler is damaged.

Ignition system of the engine emits electromagnetic wave during operation. It may interfere with medical equipments under certain circumstances, and may cause serious injury to persons with pace maker. It is recommended that persons with pace maker shall consult with their physicians and pacemaker manufacturer before using the chain saw.

Do not use a chain saw which seems to be modified.

A fire extinguisher and shovel must be available in the immediate vicinity when working in easily inflammable vegetation or when it has not rained for a long time (danger of fire).

National regulation can restrict the use of the machine. Follow your county’s regulations relating to use of chain saw.

Personal protective equipment

In order to avoid head, eye, hand or foot injuries as well as to protect your hearing the following protective equipment must be used during operation of the chain saw:

The kind of clothing should be appropriate, i. e. it should be tight-fitting but not be a hindrance. Do not wear jewellery or clothing which could become entangled with bushes or shrubs. If you have long hair, always wear a hairnet.

It is necessary to wear a protective helmet whenever working with the chain saw. The protective helmet (1) is to be checked in regular intervals for damage and is to be replaced after 5 years at the latest. Use only approved protective helmets.

The face shield (2) of the protective helmet (or the goggles) protects against sawdust and wood chips. During operation of the chain saw always wear a goggle or a face shield to prevent eye injuries.

Wear adequate noise protection equipment (ear muffs (3), ear plugs, etc.). Long time exposure to noise may cause permanent hearing disorder.

The safety jacket (4) is provided with special signal-colored shoulder straps and is comfortable and easy to care for.

The protective brace and bib overall (5) is made of a nylon fabric with 22 layers and protects against cuts. We strongly recommend its use.

Protective gloves (6) made of thick leather are part of the prescribed equipment and must always be worn during operation of the chain saw.

During operation of the chain saw safety shoes or safety boots (7) fitted with anti skid sole, steel toe caps and protection for the leg must always to be worn. Safety shoes equipped with a protective layer provide protection against cuts and ensure a secure footing.

Wear protective mask when necessary. Long time exposure to exhaust fumes, chain oil mist, and saw dust can damage your health.

Fuels/Refuelling

Stop the engine before refuelling the chain saw.

Do not smoke or work near open fires.

Let the engine cool down before refuelling.

Fuels can contain substances similar to solvents. Eyes and skin should not come in contact with mineral oil products. Always wear protective gloves when refuelling. Frequently clean and change protective clothes. Do not breathe in fuel vapors. Inhalation of fuel vapors can be hazardous to your health.

Do not spill fuel or chain oil. When you have spilt fuel or oil immediately clean the chain saw. Fuel should not come in contact with clothes. If your clothes have come in contact with fuel, change them at once.

Ensure that no fuel or chain oil oozes into the soil (environmental protection). Use an appropriate base.

Refuelling is not allowed in closed rooms. Fuel vapors will accumulate near the floor (explosion hazard).

Ensure to firmly tighten the screw plugs of the fuel and oil tanks.

Change the place before starting the engine (at least 3 m from the place of refuelling).

Fuel cannot be stored for an unlimited period of time. Buy only as much as will be consumed in the near future.

Use only approved and marked containers for the transport and storage of fuel and chain oil. Ensure children have no access to fuel or chain oil.

Putting into operation

Do not work on your own. Another person must be nearby in case of emergencies (within shouting distance).

Ensure that there are no children or other people within the working area. Pay attention to any animals in the working area, as well.

Before starting work the chain saw must be checked for perfect function and operating safety according to the prescriptions. Never use a chain saw with defects. Check especially the function of the chain brake, the correct mounting of the guide bar, the correct sharpening and tightening of the chain, the firm mounting of the chain cover, the easy motion of the throttle trigger and the function of the throttle trigger lock-out, the cleanliness and dryness of the handles, and the function of the combination switch.

When you drop the chain saw or it gets other impacts, stop using the tool immediately and perform inspection for identify significant damage or defects.

Put the chain saw only into operation if it is completely assembled. Never use the chain saw when it is not completely assembled.

Check your personal protective equipment.

Put the chain saw into operation only as described in this instruction manual. Other starting methods are not allowed.

Before starting the chain saw ensure that you have a safe footing.

When starting the chain saw it must be well supported and securely held. The guide bar and chain must not be in contact with any object.

Check chain oil reaches sufficiently to the chain.

Operation

When working with the chain saw always hold it with both hands. Take the rear handle with the right hand and the front handle with the left hand. Hold the handles tightly with your thumbs facing your fingers.

CAUTION: When releasing the throttle trigger the chain will keep on running for a short period of time (free-wheeling).

Continuously ensure that you have a safe footing.

Hold the chain saw such that you will not breathe in the exhaust gas. Do not work in closed rooms (danger of poisoning).

Switch off the chain saw immediately if you observe any changes in its operating behavior.

The engine must be switched off before checking the chain tension, tightening the chain, replacing it or clearing malfunctions.

When the sawing device is hit by stones, nails or other hard objects, switch off the engine immediately and check the sawing device.

When stopping work or leaving the working place, switch off the chain saw and put it down such that nobody is endangered.

CAUTION: Do not put the overheated power chain saw in dry grass or on any inflammable objects. The muffler is very hot (danger of fire).

CAUTION: Oil dropping from the chain or guide bar after having stopped the saw chain will pollute the soil. Always use an appropriate base.

Kickback

When working with the chain saw dangerous kickbacks may occur.

Kickback occurs when the upper part of the end of the guide bar inadvertently touches wood or other hard objects.

This causes the saw to be thrown back toward the user with great force and out of control. Risk of injury!

In order to prevent kickback, follow these rules:

-Only specially-trained persons should perform plunge cuts, i.e., piercing timber or wood with the tip of the saw!

-Never apply the end of the bar when starting to make a cut.

-Always observe the end of the guide bar. Be careful when continuing an already started cut.

-When starting to cut the chain must be running.

-Ensure that the chain is always sharpened correctly. Pay special attention to the height of the depth limiter.

-Never cut several branches at the same time. When cutting a branch ensure that no other branch is touched.

-When crosscutting a trunk be aware of the trunks next to it.

Working behavior/Method of working

Only use the chain saw during good light and visibility periods. Be aware of slippery or wet areas, and of ice and snow (risk of slipping). The risk of slipping is extremely high when working on recently peeled wood (bark).

Never work on unstable surfaces. Make sure that there are no obstacles in the working area, risk of stumbling. Always ensure that you have a safe footing.

Never saw above your shoulder height.

Never saw while standing on a ladder.

Never climb up into trees to perform sawing with the chain saw.

Do not work leaning too far over.

Guide the chain saw in such a way that no part of your body is within the elongated swivelling range of the saw.

Use the chain saw for sawing wood only.

Avoid touching the ground with the chain saw while it is still running.

Never use the chain saw for lifting up or removing pieces of wood or other objects.

Remove foreign objects such as sand, stones and nails found within the working area. Foreign objects may damage the sawing device and can cause dangerous kickback.

When sawing precut timber use a safe support (sawing jack). Do not steady the workpiece with your foot, and do not allow anyone else to hold or steady it.

Secure round pieces against rotation.

For cutting down trees or performing crosscuts the spike bumper (Z) must be applied to the wood to be cut.

Before performing a crosscut firmly apply the spike bumper to the timber, only then can the timber be cut with the chain running. For this the chain saw is lifted at the rear handle and guided with the front handle. The spike bumper serves as a centre of rotation. Continue by slightly pressing down the front handle and simultaneously pulling back the chain saw. Apply the spike bumper a little bit deeper and once again lift the rear handle.

When the timber must be pierced for cutting or longitudinal cuts are to be performed it is urgently recommended to have this carried out by specially trained persons only (high risk of kickback).

Do longitudinal lengthwise cuts at the lowest possible angle. Be very careful when doing this type of cut, as the spike bumper cannot grip.

The saw must be running whenever you remove the chain saw from the wood.

When performing several cuts the throttle trigger must be released in between.

Be careful when cutting splintery wood. Cut pieces of wood may be pulled along

(risk of injuries).

When cutting with the upper edge of the guide bar, the chain saw may be pushed in the direction of the user if the chain gets clamped. For this reason use the lower edge of the bar whenever possible. The chain saw will then be pushed away from you.

If the timber is under tension, first cut the pressure side (A). Then the crosscut can be performed on the tension side (B). Thus clamping of the guide bar can be avoided.

CAUTION:

People felling trees or cutting of branches must be specially trained. High risk of injuries!

When cutting of branches, the chain saw should be supported on the trunk. Do not use the end of the bar for cutting (risk of kickback).

Be aware of branches under tension. Do not cut free branches from below.

Never perform detensioning cuts while standing on the trunk.

Before cutting down a tree ensure that

a)only those people are within the working area which are actually involved in cutting down the tree.

b)every worker involved can withdraw without stumbling (the people should withdraw backwards in a diagonal line, i. e. at a degree of 45°).

c)the bottom part of the trunk is free from foreign objects, underbrush and branches. Make sure to have a safe footing (risk of stumbling).

d)the next working place is at least 2 1/2 tree lengths away. Before cutting down the tree check the direction of fall and make sure that there are neither people nor objects within a distance of 2 1/2 tree lengths.

Judging the tree: Direction of hanging - loose or dry branches - height of the tree - natural overhang - is the tree rotten?

Take into account the direction and speed of the wind. If strong gusts are occurring, do not do any felling.

Cutting the roots: Start with the strongest root. First do the vertical and then the horizontal cut.

Notching the trunk: The notch (A) determines the direction of fall and guides the tree. The trunk is notched perpendicular to the direction of fall and penetrates 1/3

-1/5 of the trunk diameter. Perform the cut near the ground.

When correcting the cut, always do so over the whole width of the notch.

Cut down the tree above the bottom edge of the notch (D). The cut must be exactly horizontal (B). The distance between both cuts (C) must be approx. 1/10 of the trunk diameter.

The material between both cuts serves as a hinge. Never cut it through, otherwise the tree will fall without any control. Insert felling wedges in time.

Secure the cut only with wedges made of plastic or aluminium. Do not use iron wedges. If the saw hits an iron wedge the chain can be seriously damaged or torn.

When cutting down a tree always stay sidewards of the falling tree.

When withdrawing after having performed the cut, be alert for falling branches.

When working on sloping ground the user of the chain saw must stay above or sidewards of the trunk to be cut or the tree already cut down.

Be alert for trunks which may roll towards you.

Transport and storage

When changing your location during work switch off the chain saw and actuate the chain brake in order to prevent an inadvertent start of the chain.

Never carry or transport the chain saw with the chain running. When the saw is hot, do not cover it (with a tarp, blanket, newspaper or the like). Let the saw cool down before putting it in a storage case or vehicle. Saws with catalytic converter take longer to cool down!

Use the chain protection cover during transport and storage.

Carry the chain saw with the front handle. The guide bar points backwards. Avoid coming in contact with the muffler (danger of burns).

Ensure safe positioning of the chain saw during car transportation to avoid fuel leakage, damage or injury.

Store the chain saw safely in a dry place. It must not be stored outdoors. Keep the chain saw away from children.

Before storing the chain saw over a long period of time or shipping it, the fuel and oil tanks must be completely emptied.

Perform cleaning and maintenance before storage.

Maintenance

Before performing maintenance work switch off the chain saw and pull out the plug cap.

Before starting work always check the operating safety of the chain saw, in particular the function of the chain brake. Make sure that the chain is always sharpened and tightened correctly.

Operate the chain saw only at a low noise and emission level. For this ensure the carburetor is adjusted correctly.

Regularly clean the chain saw.

Regularly check the tank cap for tightness.

Observe the accident prevention instructions issued by trade associations and insurance companies.

Do not perform any modifications on the chain saw. You will put your safety at risk.

Perform only the maintenance and repair works described in the instruction manual. All other work must be carried out by Dolmar Service.

Use only original Dolmar spare parts and accessories.

Using spare parts other than original Dolmar parts or accessories and guide bar/chain combinations or lengths which are not approved bring a high risk of accidents. We cannot accept any responsibility for accidents and damage resulting from using sawing devices or accessories which have not been approved.

Vibration

Individuals with poor circulation who are exposed to excessive vibration may experience injury to blood vessels or the nervous system.

Vibration may cause the following symptoms to occur in the fingers, hands or wrists:

“Falling asleep” (numbness), tingling, pain, stabbing sensation, alteration of skin color or of the skin.

If any of these symptoms occur, see a physician! To reduce the risk of vibration white finger, keep your hands warm, wear gloves, and make sure the saw chain is sharp.

First Aid

In case of accident make sure that a first-aid box is available in the vicinity of the cutting operations. Immediately replace any item taken from the first aid box.

CHAIN SAW’S SAFETY FUNCTION

WARNING:

Following safety functions does NOT guarantee all time protection from injury.

Only proper usage and technique can reduce the risk of kickback and other dangerous accidents.

Always check the safety functions before use.

If the chain saw fails any of the checking, switch off the engine immediately, and do NOT use the chain saw. Contact Dolmar authorized service center.

Chain brake

The chain brake is designed to stop the chain to standstill within a fraction of a second. It is activated when the kickback is sufficiently strong.

To engage the chain brake manually, push the front hand guard forward (forwards the tip of the saw) with your left hand.

To release the chain brake, pull the front hand guard towards backward (towards you).

NOTICE:

Do not accelerate the engine with the chain brake actuated (except for testing).

Always release the chain brake before starting the operation.

Checking the chain brake

1.Run the engine at idle speed.

2.Hold the chain saw with both hands. Hold the rear handle with your right hand, the front handle with your left. Make sure that the guide bar and the chain do not contact with any object.

3.Push the front hand guard using the back of your hand, until the chain brake engages.

4.Accelerate till engine reaches full throttle for less than 3 seconds. Make sure that the saw chain does not move at all.

5.Bring the engine back to idle and release the chain brake.

Checking the brake band

The brake band is at the back of the chain cover. Chain brake wears out in course of time. Have it checked and serviced by Dolmar authorized service center at least every 3 month.

Throttle trigger lock-out

Throttle trigger lock-out is designed to prevent accidental start. You can pull the throttle trigger only when the throttle trigger lock-out is pressed (i.e. when you grasp the handle).

Checking throttle trigger lock-out

Check the throttle trigger lock-out returns its original position after releasing your hand from the rear handle.

Engine stop

Make sure that the engine stops when you intend to.

Checking the engine stop

Start the engine. Then release the throttle trigger, and press down the combination switch to lower (O) position.

Adjusting saw chain tension

CAUTION:

Excessively loose saw chain may jump off the bar, and therefore presents an accident risk. If the saw chain is too loose, adjust it.

Excessively high tension of saw chain may cause breakage of saw chain, wear of

the guide bar and breakage of the adjusting screw/dial.

The saw chain may become loose after many hours of use. When you change the saw chain or after some hours of operation, check the saw chain tension before use. Properly adjusted saw chain contributes good performance and tool’s long life.

The tension of the chain is correct if the chain rests against the bottom side of the guide bar and can still be easily turned by hand.

Check the chain tension frequently, new chain tends to become longer during use.

To adjust tension of the saw chain, perform the following procedure:

1.Release the chain brake by pulling the front hand guard.

2.(For model PS-352) Unscrew the retaining nuts a bit to loosen the chain cover. (For model PS-352 TLC) Press and fully open the lever until it stops. Turn the lever counterclockwise a bit to loosen the chain cover.

3.Slightly lift and hold the tip of the guide bar.

4.(For model PS-352) Turn the chain adjusting screw to adjust the saw chain tension.

(For model PS-352 TLC) Turn the chain adjusting dial to adjust the saw chain tension.

5.Adjust the chain tension until the lower side of the saw chain fits in the guide bar rail (see circle in the figure).

During adjusting the chain tension, keep lifting up the tip of the guide bar.

6.Keep holding the guide bar lightly, and tighten the chain cover after adjusting the chain tension.

(For model PS-352) Tighten the retaining nuts to secure the chain cover.

(For model PS-352 TLC) Turn the lever fully clockwise to secure the chain cover. Then press and close the lever.

7.Make sure that the saw chain does not loose at lower side but it fits snugly against the lower side of the bar.

BEFORE USE

WARNING:

AVOID SKIN AND EYE CONTACT. Mineral oil products degrease your skin. If your skin comes in contact with these substances repeatedly and for an extended period of time, it may dry your skin. Various skin diseases may result. In addition, allergic reactions are known to occur. Eyes can be irritated by contact with oil. If oil comes into your eyes, immediately wash them with clear water. If your eyes are still irritated, see a doctor immediately.

Fuel

CAUTION:

Be especially careful when handling gasoline.

Do not smoke. Keep tool well away from open flames, spark, or fire (explosion hazard).

Fuel mixture

This tool is powered by a high performance air-cooled two stroke engine. It runs on a mixture of gasoline and two-stroke engine oil.

The engine is designed for unleaded regular gasoline with a min. octane value of 91 RON (89 AKI), and ethanol contained no more than 10%. In case no such fuel is available, you can use fuel with a higher octane value. This will not affect the engine.

In order to obtain an optimum engine output and to protect your health and the environment use unleaded fuel only.

To lubricate the engine, use synthetic oil for two-stroke air-cooled engines (Dolmar genuine oil or quality grade JASO FC (ISO EGC) or upper). Mix engine oil with fuel.

CAUTION:

• Do not use ready-mixed fuel from petrol stations.

The correct mixture ratio: 50:1 i.e. mix 50 parts gasoline with 1 part oil.

NOTE:

For preparing the fuel-oil mixture first mix the entire oil quantity with half of the fuel required, then add the remaining fuel. Thoroughly shake the mixture before filling it into the chain saw tank.

Do not add more engine oil than specified. Incorrect mixture ratio of oil results in making more polluting combustion residues. It also causes clog exhaust channel in the cylinder and muffler, and causes poor performance and excessive fuel consumption.

The Storage of Fuel

Fuels have a limited storage life. Fuel mixtures age through evaporation, especially at high temperatures. Aged fuel and fuel mixtures can cause starting problems and damage the engine. Purchase only that amount of fuel, which will be consumed over the next few months. At high temperatures, once fuel has been mixed it should be used up in 6-8 weeks.

Preserve fuel only in proper containers, in dry, cool, secure locations.

Chain oil

Use oil with adhesive additive for lubricating the chain and guide bar. The adhesive additive prevents the oil from being flung off the chain too quickly.

We recommend the use of Dolmar genuine chain oil or chain oil which is biodegradable in order to protect the environment. The use of bio-degradable oil may even be required by local regulations.

Bio-degradable oil is stable only for a limited period of time. Use it within 2 years from the date of manufacture (printed on the container).

Important note on bio-degradable chain oils

If you are not planning to use the saw again for an extended period of time, empty the oil tank and put in a small amount of regular engine oil (SAE 30), and then run the saw for a time. This is necessary to flush out all remaining bio-degradable oil from the oil tank, oil-feed system, chain and guide bar, as many such oils tend to leave sticky residues over time, which can cause damage to the oil pump or other parts.

NEVER USE WASTE OIL

Waste oil is very dangerous for the environment.

Waste oil contains high amounts of carcinogenic substances.

Residues in waste oil result in extreme wear and scuff at the oil pump and the sawing device.

In case of damage caused by using waste oil or inappropriate chain oil the product warranty will be void.
