NOTE: Advises you of information or instructions vital to the

operation or maintenance of the equipment.

DANGER:

Failure to obey a safety warning will result in serious injury to yourself or to others. Always follow the safety precautions to reduce the risk of fire, electric shock and personal injury.

KICKBACK SAFETY PRECAUTIONS

• With a basic understanding of kickback, you can reduce or eliminate the element of surprise. Sudden surprise contributes to accidents.

• Grip trimmer firmly. Hold the pole saw/ trimmer unit firmly with both hands when the motor is running. Keep one hand on the grip and the other hand on the handle.

• Do not let the nose of the guide bar contact a log, branch, ground or other obstruction.

• Always cut with the engine running at full speed. Fully squeeze the throttle trigger and maintain a steady cutting speed.

• Do not over reach.

• Follow the manufacturer’s sharpening and maintenance instructions for the saw chain.

• Use only replacement bars and chains specified by the manufacturer or the equivalent.

SAFETY WARNINGS FOR ELECTRIC POWERHEADS

READ ALL INSTRUCTIONS BEFORE OPERATING

• Carefully read and understand the operator's manual of the unit that powers this attachment.

• Read this operating instruction manual carefully. Be thoroughly familiar with the controls and the proper use of the equipment. Know how to stop the unit and disengage the controls quickly.

• Do not operate this unit when tired, ill, or under the influence of alcohol, drugs, or medication.

• Never allow children to operate the equipment. Never allow adults unfamiliar with the instructions to use the unit. Never allow adults to operate the equipment without proper instruction.

• All guards and safety attachments must be installed properly before operating the unit.

POLE SAW OPERATING PROCEDURES

•

Keep bystanders, especially children and pets, at least 50 ft (15 m) away.

• Wear safety glasses or goggles that are marked as meeting ANSI Z87.1–1989 standards, and ear/hearing protection when operating this unit. Wear a face or dust mask if the operation is dusty.

• Wear heavy, long pants, boots, gloves and a long sleeve shirt. Do not wear loose clothing, jewelry, short pants, sandals or go barefoot. Secure hair above shoulder level.

• Use the unit only in daylight or good artificial light.

• Use the right tool. Only use this tool for the purpose intended.

• Always stop the engine when operation is delayed or when walking from one location to another.

• IMPORTANT SAFETY INSTRUCTIONS •

WARNING:

When using the unit, you must follow the safety rules. Please read these instructions before operating the unit in order to ensure the safety of the operator and any bystanders. Please keep these instructions for later use.

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 action, kicking the guide bar rapidly 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 lose control of the saw, which could result in serious injury to the user. Do not rely exclusively upon the safety devices built into your saw. As a pole saw user, you should take several steps to keep your cutting jobs free from accident or injury.

WARNING:

To reduce the risk of electrical shock, use only extension cords approved for outdoor use, such as an extension cord of cord type SW-A, SOW-A, STW-A, STOWA, SJW-A, SJOW-A, SJTW-W or SJTOW-A. Extension cords are available from your local retailer. Use only roundjacketed extension cords approved for outdoor use.

RULES FOR SAFE OPERATION

• CORD SETS: Make sure your cord set is in good condition. When using a cord set, be sure to use a cord that is heavy enough to carry the current that your unit will draw. An undersized cord set will cause a drop in line voltage resulting in loss of power and overheating. See the operator’s manual for the unit that will power this attachment for the recommended cord size.

• Inspect all extension cords and the unit power connection periodically. Look closely for deterioration, cuts or cracks in the insulation. Also inspect the connections for damage. Replace the cords if any defects or damage appear.

• Prevent disconnection of the electric powerhead from extension cord during operation by using a plug-receptacle retaining strap, connector, or by making a knot as shown below:

• Avoid dangerous environments. Never operate your unit in damp or wet conditions. Moisture is a shock hazard.

• Do not use the unit in the rain. Do not use in or around water. Do not use on wet hedges or shrubbery.

• Do not handle the plug or unit with wet hands or standing on any wet surfaces.

• Do not leave the unit plugged in when not in use, changing attachments or add-ons, or while being serviced.

OTHER SAFETY PRECAUTIONS

• DO NOT operate a pole saw with one hand! Serious injury to the operator, helpers, or bystanders may result from one-handed operation. A pole saw is intended for two-handed use.

• Do not operate a pole saw if you are fatigued.

• Do not wear loose clothing or jewelry, as they can get caught in moving parts. Non-skid footwear is recommended when working outdoors. Wear protective hair covering to contain long hair.

• Use safety glasses, safety footwear, snug fitting clothing, protective gloves, and protective hearing and head gear.

• Keep the work area clean. Cluttered areas invite injuries. Do not start cutting until you have a clear work area, secure footing, and a planned retreat path from the falling branches.

• Stay Alert. Watch what you are doing. Use common sense. Do not operate the pole saw when you are tired. Keep all parts of your body away from the saw chain when the motor is operating. Before you start the saw, make sure the saw chain is not contacting anything.

• Disconnect the pole saw when not in use, before servicing, and when changing accessories and attachments such as saw chain and guard.

• Check damaged parts. Before further use of the pole saw, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting, and any other conditions that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced by an authorized service center, unless otherwise indicated in this instruction manual.

• Use extreme caution when cutting small sized brush and sapling, as slender material may catch the saw chain and be whipped toward you or pull you off balance.

• Do not operate a pole saw in a tree unless you are specifically trained to do so. 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.

• Do not expose the pole saw to rain. Do not use the pole saw in damp or wet locations.

•

Do not use the pole saw in the presence of flammable liquids or gases.

• All pole saw service, other than the items listed in the operator’s manual safety and maintenance instructions, should be performed by competent pole saw personnel. Do not attempt to repair it yourself; there are no user serviceable parts inside.

• The pole saw will do a better and safer job when used at the rate for which it was intended.

• Use the right tool. Cut wood only. Do not use the pole saw for purposes for which it was not intended. For example, do not use the pole saw for cutting plastic, masonry, or non-building materials.

•

Use devices, such as low-kickback chain, guide bar nose guards, chain brakes and special guide bars, which reduce the risks associated with kickback.

• There are no other replacement components for achieving kickback protection in accordance with CSA Z62.3.

• Do not operate a pole saw that is damaged, improperly adjusted, or not completely and securely assembled. Be sure that the saw chain stops moving when the trigger is released.

• Do not attempt operations beyond your capacity or experience.

• Never remove, modify or make inoperative any safety device furnished with your unit.

• This saw is intended for infrequent use by homeowner’s, cottagers and campers, and for such general applications such as clearing and pruning. It is not intended for prolonged use. If the intended use involves prolonged periods of operation, this may cause circulatory problems in the user’s hands due to vibration. It may be appropriate to use a saw having an anti-vibration feature.

•

Safety clothing required by your safety organizations, government regulations, or your employer should be used; otherwise, snug fitting clothing, safety footwear, and hand and ear protection should be worn.

• Low-kickback saw chain is chain that has met the kickback performance requirements of ANSI B175.1-1991 and is in accordance with CSA Z62.3. Do not use other replacement chain unless it has met these requirements for your specific model.

• Do not use any other cutting attachment or accessories. Use only original equipment manufacturer replacement parts and accessories, which are designed specifically to enhance the performance and maximize the safe operation of our products. Failure to do so may cause poor performance and possible injury. Use only the chain and bar supplied with this product. Do not use any other cutting attachment. Use of such attachments will void your factory warranty and could result in serious bodily injury.

• Never touch the chain or attempt to service the saw while the engine is running. Make sure all moving parts have stopped. Allow the chain to cool, as the chain can be hot.

• Check the bar and chain at frequent intervals for proper adjustment. Make sure the bar and chain are properly tightened and sharpened. Visually inspect for damage. Repair any damage before restarting or operating the pole saw.

• Do not cut near electrical cables or power lines.

• Do not use the pole saw to fell a tree. Use a standard chain saw for this application.

MAINTENANCE AND STORAGE

• Allow the unit to cool before storing or transporting. Be sure to secure the unit while transporting.

• Always use the transport guard on the bar and chain during transportation and storage.

• Store the unit in a locked up and dry or high and dry place to prevent unauthorized use or damage, out of the reach of children.

• Never douse or squirt the unit with water or any other liquid. Keep handles dry, clean and free from debris. Clean after each use.

• Keep these instructions. Refer to them often and use them to instruct other users. If you loan someone this unit, also loan them these instructions.

• Only qualified personnel should perform any repairs or maintenance procedures that are not described in this manual.

OPERATING INSTRUCTIONS

OPERATING PRECAUTIONS

1. Keep bystanders 50 feet (15 meters) away when operating the saw.

2. Do not use the pole saw to cut down trees. Use a chain saw without a pole attachment.

3. Make sure the oil tank is full and oil is lubricating the chain prior to starting.

4. Grip pole saw/ trimmer securely—one hand on the grip, the other on the handle.

5. Keep finger off the trigger until ready to make cut.

6. Before starting the pole saw, make sure the chain is not touching anything.

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

8. Do not force the chain saw while cutting. Apply light pressure. It will do the job better and safer at the rate for which it was intended.

9. When cutting limbs or branches that are under tension, use extreme caution. Be alert for wood springing back. When wood tension is released, the limb could spring back and strike operator causing severe injury or death.

10. When carrying pole saw from one place to another:

• hold pole at balance point

• keep guide bar and chain to the rear

11. Do not cut small brush and saplings with the pole saw. Slender matter may catch in the chain and be whipped toward you. This could also pull you off balance.

12. Never stand directly under the limb you are trimming. Always position yourself out of the path of falling debris (Fig. 4).

13. Never stand on a ladder or other type of unstable support while using the pole saw.

14. Always use both hands to operate pole saw. Keep a firm, steady pressure on the pole saw while cutting, but do not try to force the saw through the wood.

15. Keep other persons away from cutting end of pole saw and at a safe distance from work area. (Fig. 5).

16. Do not use the pole saw near cable, electric power or telephone lines. Maintain a minimum clearance of 50 feet (15 m) from all power lines (Fig. 6).

STARTING INSTRUCTIONS

Start and operate your pole saw without assistance. For specific starting instructions, see the appropriate section of your powerhead manual. Proper starting methods reduce the risk of injury.

WARNING:

Dress properly to reduce the risk of injury when operating this unit. Do not wear loose clothing or jewelry. Wear eye and ear/hearing protection. Wear heavy long pants, boots and gloves. Wear a hard hat. Use a full face shield when needed.

WARNING:

To reduce the risk of fire and burn injuries, start the engine at least 30 ft. (9.1 m) from the fueling spot, outdoors only.

1. Place the pole saw on firm ground or other solid surface in an open area.

2. Maintain good balance and secure footing.

OPERATING TIPS

• Avoid kickback. Kickback can result in severe injury or death.

• Do not operate the pole saw while in a tree, on a ladder or any

other unstable work surface, or in any awkward position. You may lose control of the pole saw causing severe injury.

• Do not extend your arms above shoulders when using the pole

saw.

• Seek professional help if you are facing conditions beyond your

ability.

• Trimming a tree is the process of cutting limbs from a living tree.

Make sure your footing is firm. Keep your feet apart. Divide your weight evenly on both feet.

• Before starting unit, always check the chain lubrication and oil

tank level.

NOTE: The chain must be continously coated with oil to function

properly. Make sure that the oil adjustment screw is set appropriately.

To trim a limb (pruning):

1. Make the first cut six inches from tree trunk on the underside of the limb. Use the top of the guide bar to make this cut. Cut a third of the way through the diameter of the limb (Fig. 7).

2. Move two to four inches farther out on the limb. Make the second cut from above the limb. Continue the cut until you cut the limb off.

3. Make the third cut as close to the tree trunk as possible on underside of limb stub. Use the top of the guide bar to make this cut. Cut a third through the diameter of stub.

4. Make the fourth cut directly above the third cut. Cut down to meet the third cut. This will remove the limb stub.

WARNING:

If the oil tank runs out, the oil ajustment screw hole becomes clogged, or the chain fails to get proper lubrication in any fashion, the chain will overheat and cause irreversible damage to the unit and may result in severe injury. Excessive heat from friction can lead the chain to catastrophically fail and come off the bar while operating.

WARNING:

Do not

rely exclusively upon the safety devices built into your saw. As a chain saw user, you should take several steps to keep your cutting jobs free from accident or injury.

WARNING:

Do not use the pole saw to cut limbs larger

than 4” (10 cm) in diameter.
