1. For safe operation

WARNING

This chainsaw has been especially designed for tree maintenance and should therefore only be used by trained operators when working on trees.

1. Never operate a chain saw when you are fatigued, ill, or upset, or under the influence of medication that may make you drowsy, or if you are under the influence of alcohol or drugs.

2. Use safety footwear, snug fitting clothing and eye, hearing and head protection devices.

Use the vibration-proof glove.

3. Keep the saw chain sharp and the saw, including the AV system, well maintained. A dull chain will increase cutting time, and pressing a dull chain through wood will increase the vibrations transmitted to your hands.

A saw with loose components or with damaged or worn AV buffers will also tend to have higher vibration levels.

4. Always use caution when handling fuel. Wipe up all spills and then move the chain saw at least 3 m from the fueling point before starting the engine.

5. Eliminate all sources of sparks or flame (i.e. smoking, open flames, or work that can cause sparks) in the areas where fuel is mixed, poured, or stored.

6. Do not smoke while handling fuel or while operating the chain saw.

7. Do not allow other persons to be near the chain saw when starting or cutting. Keep bystanders and animals out of the work area. Children, pets and bystanders should be a minimum of 10 m away when you start or operate the chain saw.

8. Never start cutting until you have a clear work area, secure footing, and a planned retreat path from the falling tree.

9. Always hold the chain saw firmly with both hands when the engine is running. Use a firm grip with thumb and fingers encircling the chain saw handles.

01-G3000_GB_205＿二.indd 3

10. Keep all parts of your body away from the saw chain when the engine is running.

11. Before you start the engine, make sure the saw chain is not contacting anything.

12. Always carry the chain saw with the engine stopped, the guide bar and saw chain to the rear, and the muffler away from your body.

13. Always inspect the chain saw before each use for worn, Ioose, or damaged parts. Never operate a chain saw that is damaged, improperly adjusted, or is not completely and securely assembled. Be sure that the saw chain stops moving when the throttle control trigger is released.

14. All chain saw service, other than the items listed in the Owner’s Manual, should be performed by competent chain saw service personnel. (E.g., if improper tools are used to remove the flywheel, or if an improper tool is used to hold the flywheel in order to remove the clutch, structural damage to the flywheel could occur which could subsequently cause the flywheel to disintegrate.)

15. Always shut off the engine before setting it down.

16. Use extreme caution when cutting small size brush and saplings because slender material may catch the saw chain and be whipped toward you or pull you off balance.

17. When cutting a limb that is under tension, be alert for spring- back so that you will not be struck when the tension in the wood fibers is released.

18. Never cut in high wind, bad weather, when visibility is poor or in very high or low temperatures. Always check the tree for dead branches which could fall during the felling operation.

19. Keep the handles dry, clean and free of oil or fuel mixture.

20. Operate the chain saw only in well ventilated areas. Never start or run the engine inside a closed room or building. Exhaust fumes contain dangerous carbon monoxide.

21. Do not operate the chain saw in a tree unless specially trained to do so.

22. Guard against kickback. Kickback is the upward motion of the guide bar which occurs when the saw chain at the nose of the guide bar contacts an object. Kickback can lead to dangerous loss of control of the chain saw.

23. When transporting your chain saw, make sure the appropriate guide bar scabbard is in place.

KICKBACK SAFETY PRECAUTIONS

FOR CHAIN SAW USERS front handle, when the engine is running. Use a firm grip with thumbs and fingers encircling the chain saw handles. A firm grip will help you reduce kickback and maintain control of the saw.

(3) Make certain that the area in which you are cutting is free from obstructions. Do not let the nose of the guide bar contact a log, branch, or any other obstruction which could be hit while you are operating the saw.

(4) Cut at high engine speeds.

(5) Do not overreach or cut above shoulder height.

(6) Follow the manufacturer’s sharpening and maintenance instructions for the saw chain.

(7) Only use replacement bars and chains specified by the manufacturer or the equivalent.

WORSE EFFECTS OF VIBRATION

If you continue to use high-vibration tools these symptoms will probably get worse, for example:

• the numbness in your hands could become permanent and you won’t be able to feel things at all;

• you will have difficulty picking up small objects such as screws or nails;

• the vibration white finger could happen more frequently and affect more of your fingers.

WARNING

• Kickback may occur when the nose or tip of the guide bar touches an object, or when the wood closes in and pinches the saw chain in the cut.

Tip contact in some cases may cause a lightning fast reverse reaction,kicking the guide bar up and back towards the operator. Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back towards the operator. Either of these reactions may cause you to Iose control of the saw, which could result in serious personal injury.

• Do not rely exclusively on the safety devices built into your saw. As a chain saw user you should take several steps to keep cutting jobs free from accident or injury.

FOR PROTECTING YOUR BODY FROM VIBRATION

Please observe the following matter, in order to protect the health of your body.

1. Always use the right tool for each job (to do the job more quickly and expose you to less hand-arm vibration).

2. Check tools before using them to make sure they have been properly maintained and repaired to avoid increased vibration caused by faults or general wear.

3. Make sure cutting tools are kept sharp so that they remain efficient.

4. Reduce the amount of time you use a tool in one go, by doing other jobs in between.

5. Avoid gripping or forcing a tool or workpiece more than you have to.

6. Store tools so that they do not have very cold handles when next used.

7. Encourage good blood circulation by:

• keeping warm and dry (when necessary, wear gloves, a hat, waterproofs and use heating pads if available);

• giving up or cutting down on smoking because smoking reduces blood flow; and massaging and exercising your fingers (1) With a basic understanding of kickback you can reduce or eliminate the element of surprise. Sudden surprise contributes to accidents.

(2) Keep a good grip on the saw with both hands, the right hand on the rear handle, and the left hand on the

DISPOSAL

• When you dispose of the machine, do not disassemble the machine.

• When you dispose of the machine, fuel, chain oil, be sure to follow your local regulations.

WORKING WITH TREE SERVICE CHAIN-SAWS

FROM A ROPE AND HARNESS

This chapter sets out working practices to reduce the risk of injury from tree service chainsaws when working at height from a rope and harness. While it may form the basis of guidance and training literature, it should not be regarded as a substitute for formal training.

General requirements working at height

Operators of tree service chainsaws working at height from a rope and harness should never work alone. A competent ground worker trained in appropriate emergency procedures should assist them.

Operators of tree service chainsaws for this work should be trained in general safe climbing and work positioning techniques and shall properly equipped with harnesses, ropes, strops, karabiners and other equipment for maintaining secure and safe working positions for both themselves and the saw.

Preparing to use the saw in the tree

The chainsaw should checked, fuelled, started and warmed up by the ground worker before it is sent up to the operator in the tree. The chainsaw should be fitted with a suitable strop for attaching to the operator’s harness: a) choke the strop around the attachment point on the rear of the saw (A); ness;

A b) provide suitable karabiners to allow indirect (i.e. via the strop) and direct attachment (i.e. at the attachment point on the saw) of saw to the operators harc) ensure the saw is securely attached when it is being sent up to the operator; d) ensure the saw it secured to the harness before it is disconnected from the means of ascent.

G3000

The saw should only be attached to the recommended attachment points on the harness. These may be at mid-point (front or rear) or at the sides. Where possible attaching the saw to centre rear mid-point will keep it clear of climbing lines and support its weight centrally down the operator’s spine.

When moving the saw from any attachment point to another, operators should ensure it is secured in the new position before releasing it from the previous attachment point.

Using the chainsaw in the tree

An analysis of accidents with these saws during tree service operations shows the primary cause as being inappropriate one-handed use of the saw. In the vast majority of accidents, operators fail to adopt a secure work position witch allows them to hold both handles of the saw. This results in an increased risk of injury due to:

• not having a firm grip on the saw if it kicks back;

• a lack of control of the saw such that it is more liable to contact climbing lines and operators body (particularly the left hand and arm)

• losing control from insecure work position resulting in contact with the saw (unexpected movement during operation of the saw)

Securing the work position for two-handed use

To allow the operator to hold the saw with both hands, they should as general rule, aim for secure work position where they are operating the saw at:

• hip level when cutting horizontal sections;

• solar plexus level when cutting vertical sections.

Where the operator is working close into vertical stems with a low lateral forces on their work position, then a good footing may be all that is needed to maintain a secure work position. However as operators move away from the stem, they will need to take steps to remove or counteract the increasing lateral forces by, for example, a re-direct of the main line via a supplementary anchor point or using an adjustable strop direct from the harness to a supplementary anchor point.

GB-5

12.5.14 10:27:05 AM

G3000

Gaining a good footing at the working position can be assisted by use of a temporary foot stirrup created from an endless sling.

One-hand use of the chainsaw

Operators should not use tree service chainsaws onehanded in place of unstable work positioning or in preference to a handsaw when cutting small diameter wood at the branch tips.

Tree service chainsaws should only be used onehanded where:

• the operator cannot gain a work position enabling two-handed use; and

• they need to support their working position with one hand; and

• the saw is being used at full stretch, at right angles to and out of line with the operator’s body.

Starting the saw in the tree

When starting the saw in the tree, the operator should: a) apply the chain brake before starting; b) hold saw on either the left or right of the body when starting:

1) on the left side hold the saw with either the left hand on the front handle or the right hand on the rear handle and thrust the saw away from the body while holding the pull starter cord in the other hand;

2) on the right side, hold the saw with the right hand on either handle and thrust the saw away from the body while holding the pull starter cord in the left hand.

The chain brake should always be engaged before lowering a running saw onto its strop.

Operators should always check the saw has sufficient fuel before undertaking critical cuts.

Operators should never:

• cut with the kickback zone at the tip of the chainsaw guide bar

• ‘hold and cut’ sections

• attempt to catch falling sections.

Freeing a trapped saw

If the saw should become trapped during cutting, operators should:

• switch off the saw and attach it securely to the tree inboard (i.e. towards the truck side) of the cut or to a separate tool line;

• pull the saw from the kerf whilst lifting the branch as necessary;

• if necessary, use a handsaw or second chain saw to release the trapped saw by cutting a minimum of 30 cm away from the trapped saw.

Whether a handsaw or a chainsaw is used to free a stuck saw, the release cuts should always be outboard

(toward the tips of the branch), in order to prevent the saw being taken with the section and further complicating the situation.

4. Fuel and Chain Oil

■ FUEL

WARNING

• Gasoline is very flammable. Avoid smo king or bringing any flame or sparks near fuel. Make sure to stop the engine and allow it cool before refueling the unit. Select outdoor bare ground for fueling and move at least 3 m (10 ft) away from the fueling point before starting the engine.

• The Zenoah engines are lubricated by oil specially formulated for air-cooled 2-cycle gasoline engine use.

If Zenoah oil is not available, use an anti-oxidant added quality oil expressly labeled for air-cooled

2-cycle engine use (JASO FC GRADE OIL or ISO EGC

GRADE).

• Do not use BIA or TCW (2-stroke water-cooling type) mixed oil.

■ RECOMMENDED MIXING RATIO

GASOLINE 50 : OIL 1

<when using ZENOAH genuine oil>

• Exhaust emission are controlled by the funda­ mental engine parameters and components (eq., carburation, ignition timing and port timing) without addition of any major hardware or the introduction of an inert material during com bustion.

• These engines are certified to operate on unleaded gasoline.

• Make sure to use gasoline with a minimum octane number of 89RON (USA/Canada: 87AL).

• If you use a gasoline of a lower octane value than prescribed, there is a danger that the engine temperature may rise and an engine problem such as piston seizing may consequently occur.

• Unleaded gasoline is recommended to reduce the contamination of the air for the sake of your health and the environment.

• Poor quality gasolines or oils may damage sealing rings, fuel lines or fuel tank of the engine.

■ HOW TO MIX FUEL

WARNING

• Pay attention to agitation.

1. Measure out the quantities of gasoline and oil to be mixed.

2. Put some of the gasoline into a clean, approved fuel container.

3. Pour in all of the oil and agitate well.

4. Pour in the rest of gasoline and agitate again for at least one minute. As some oils may be difficult to agitate depending on oil ingredients, sufficient agitation is necessary for the engine to last long. Be careful that, if the agitation is insufficient, there is an increased danger of early piston seizing due to abnormally lean mixture.

5. Put a clear indication on the outside of the container to avoid mixing up with gasoline or other containers.

6. Indicate the contents on outside of container for easy identification.

G

B

■ FUELING THE UNIT

1. Untwist and remove the fuel cap. Rest the cap on a dustless place.

2. Put fuel into the fuel tank to 80% of the full capacity.

3. Fasten the fuel cap securely and wipe up any fuel spillage around the unit.

WARNING

1. Select bare ground for fueling.

2. Move at least 10 feet (3 meters) away from the fueling point before starting the engine.

3. Stop the engine before refueling the unit. At that time, be sure to sufficiently agitate the mixed gasoline in the container.

■ FOR YOUR ENGINE LIFE, AVOID:

1. FUEL WITH NO OIL (RAW GASOLINE) – It will cause severe damage to the internal engine parts very quickly.

2. GASOHOL – It can cause deterioration of rubber and/ or plastic parts and disruption of engine lubrication.

3. OIL FOR 4-CYCLE ENGINE USE – It can cause spark plug fouling, exhaust port blocking, or piston ring sticking.

4. Mixed fuels which have been left unused for a

period of one month or more may clog the carburetor and result in the engine failing to operate properly.

5. In the case of storing the product for a long period of time, clean the fuel tank after rendering it empty.

Next, activate the engine and empty the carburetor of the composite fuel.

6. In the case of scrapping the used mixed oil container, scrap it only at an authorized repository site.

NOTE

As for details of quality assurance, read the description in the section Limited Warranty carefully. Moreover, normal wear and change in product with no functional influence are not covered by the warranty. Also, be careful that, if the usage in the instruction manual is not observed as to the mixed gasoline, etc. described therein, it may not be covered by the warranty.

■ CHAIN OIL

Use motor oil SAE #10W-30 all year round or SAE

#30 ~ #40 in summer and SAE #20 in winter.

NOTE

Do not use wasted or regenerated oil that can cause damage to the oil pump.

6. Sawing

• Before proceeding to your job, read the section “For Safe

Operation”. It is recommended to first practice sawing easy logs. This also helps you get accustomed to your unit.

• Always follow the safety regulations. The chain saw must only be used for cutting wood. It is forbidden to cut other types of material. Vibrations and kickback vary with different materials and the requirements of the safety regulations would not be respected. Do not use the chain saw as a lever for lifting, moving or splitting objects. Do not lock it over fixed stands. It is forbidden to hitch tools or applications to the PTO other than those specified by the manufacturer.

• It is not necessary to force the saw into the cut. Apply only light pressure while running the engine at full throttle.

• When the saw chain is caught in the cut, do not attempt to pull it out by force, but use a wedge or a lever to open the way.

• If the guide bar and saw chain becomes caught in wood while operating it, stop the engine.

Do not pry the handle with excessive force.

Use a wedge to remove the chain instead.

■ FELLING A TREE

Felling direction

Notch cut

1. Decide the felling direction considering the wind, lean of the tree, location of heavy branches, ease of completing the task after felling and other factors.

2. While clearing the area around the tree, arrange a good foothold and retreat path.

3. Make a notch cut one-third of the way into the tree on the felling side.

4. Make a felling cut from the opposite side of the notch and at a level slightly higher than the bottom of the notch.

When you fell a tree, be sure to warn neighboring workers of the danger.

Bucking and Limbing

• Always ensure your foothold. Do not stand on the log.

• Be alert to the rolling over of a cut log. Especially when working on a slope, stand on the uphill side of the log.

• Follow the instructions in “For Safe Operation” to avoid kickback of the saw.

Before starting work, check the direction of bending force inside the log to be cut. Always finish cutting from the opposite side of the bending direction to prevent the guide bar from being caught in the cut.

■ Saw Chain

WARNING

It is very important for smooth and safe operation to always keep the cutters sharp.

The cutters need to be sharpened when:

• Sawdust becomes powder-like.

• You need extra force to saw in.

• The cut path does not go straight.

• Vibration increases.

• Fuel consumption increases.

WARNING

Be sure to round off the front edge to reduce the chance of kickback or tie-strap breakage.

Make sure every cutter has the same length and edge angles as illustrated.
