3. For safe operation
WARNING
• This chainsaw has been especially designed for tree maintenance and should therefore only be used by trained operators when working up in the trees.
• Under no circumstances may the design of the ma­chine be modified without the permission of the manu­facturer. Always use genuine accessories. Non-autho­rized modifications and/or accessories can result in serious personal injury or the death of the operator or others.
•A chain saw is a dangerous tool if used carelessly or incorrectly and can cause serious, even fatal injuries. It is very important that you read and understand the contents of this operator’s manual.
7. 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.)
8. Always shut off the engine before setting it down.
BASIC SAFETY RULES
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 vibration reducing gloves. Most chain saw accidents happen when the chain touches the opera­tor. Personal protective equipment can­not eliminate the risk of injury but it will reduce the degree of injury.
3. Do not allow other person 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.
9. Never cut in high wind, bad weather, when visibility is poor or in very high or low temperatures.
10. Operate the chain saw only in well ventilated areas. Never start or run the engine inside a closed room or building and potentially explosive at­mosphere. Exhaust fumes contain dangerous carbon monoxide.
11. Never touch the cover, guide bar, saw chain or nut with bare hands while the engine is in operation or immedi­ately after shutting down the engine. Doing so could result in serious burns

4. Never start cutting until you have a clear work area, secure footing, and a planned retreat path from the fall­ing tree.
5. Always hold the chain saw firmly with both hands when the chain saw is running. Use a firm grip with thumb and fingers encircling the chain saw handles.
6. Keep all parts of your body away from the saw chain when the engine is run­ning.
GZ3500T
BEFORE USE
1. Keep the saw chain sharp and the anti-vibration 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.
2. Before you start the engine, make sure the saw chain is not contacting anything.
3. 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.
CUTTING
1. 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.
2. 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.
3. Always check the tree for dead branches which could fall during the felling operation.
4. Do not operate the chain saw in a tree unless specially trained to do so.
5. Never use a chain saw by holding it with one hand. A chain saw is not safe if controlled with one hand; you can cut yourself. Always have a secure, firm grip around the handles with both hands.
FUEL SAFETY
1. Always use caution when handling fuel. Wipe up all spills and then move the chain saw at least 10 ft(3 m) from the fueling point before starting the engine.
2. 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.
3. Do not smoke while handling fuel or while operating the chain saw.
4. Keep the handles dry, clean and free of oil or fuel mixture.
5. Always store fuel in an approved con­tainer designed for that purpose.
STORAGE
1. Always store the chain saw and fuel so that there is no risk of leakages or fumes coming into contact with sparks or naked flames from electri­cal equipment, electric motors, re­lays/switches, boilers and the like.
2. For longer periods of storage or for transport of the chain saw, the fuel and chain oil tanks should be emp­tied.
3. When the chain saw is in storage make sure the appropriate guide bar scabbard is in place in order to pre­vent accidental contact with the sharp chain. Even a non-moving chain can cause serious cuts to your­self or persons you bump into with an exposed chain.
U S
TRANSPORT
1. 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.
2. When transporting your chain saw, make sure the appropriate guide bar scabbard is in place.

KICKBACK SAFETY PRECAUTIONS FOR CHAIN SAW USERS
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.
(1) With a basic understanding of kick-
back 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 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. (full
throttle)
(5) Do not overreach or cut above shoul-
der height.
(6) If you have to cut branches or the like
that are above shoulder height, a working platform or scaffold is rec­ommended.
(7) Follow the manufacturer’s sharpening
and maintenance instructions for the saw chain.
(8) Only use replacement bars and
chains specified by the manufacturer.
FOR PROTECTING YOUR BODY FROM 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 white finger syndrome could occur more fre­quently and affect more of your fingers.
Please observe the following, 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 at one time, 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 used.
7. Encourage good blood circulation by:
• keeping warm and dry (when necessary, wear gloves, a hat, waterproofs and use heating pads if available);
• give up or cut down on smoking because smoking reduces blood flow; massage and exercise your fin­gers to increase blood circulation.
DISPOSAL
When disposing of your machine, fuel or oil in the machine, be sure to follow your local regulations.
