• Keep all bystanders, children, and pets at least 50 ft. away.

• Stay alert, watch what you are doing, and use common sense when operating a power tool. Do not use tool while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating power tools may result in serious personal injury.

• Do not operate in poor lighting.

• Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enables better control of the tool in unexpected situations.

• Keep all parts of your body away from any moving part.

• Inspect unit before each use for loose fasteners and damaged or missing parts. Correct before using the attachment. Failure to do so can cause serious injury.

• Use only original manufacturer’s replacement parts. Failure to do so may cause poor performance, and possible injury, and will void your warranty.

• Do not, under any circumstance, use any attachment or accessory on this product, which was not provided with the product, or identified as appropriate for use with this product in the operator’s manual.

• Avoid dangerous environments. Do not use the attachment in damp or wet locations. Do not use in rain.

• Use the right attachment. Do not use attachments for any job except that for which it is intended.

• Keep hands away from the cutting area. Keep hands away from blades. Do not reach underneath work or around or over the blade while blade is rotating. Do not attempt to remove cut material when the blade is moving.

• Blade coasts after being turned off.

• Do not touch areas around the muffler or cylinder of a gas power head. These parts get hot from operation. Contact with hot surfaces could result in possible serious personal injury.

• Always stop the engine or motor and remove the spark plug wire or disconnect from the power supply before making any adjustments or repairs except for carburetor adjustments.

• Always use two hands when operating the pruner attachment. Hold the pruner attachment and power head with both hands to avoid loss of control.

• Do not use the pruner attachment in bad weather conditions, especially when there is a risk of lightning. This decreases the risk of being struck by lightning.

• Maintain Appliance With Care – Keep cutting edge sharp and clean for best performance and to reduce the risk of injury. Follow instructions for lubricating and changing accessories. Inspect appliance cord periodically, and if damaged, have it repaired by an authorized service facility. Inspect extension cords periodically and replace if damaged.

• Check Damaged Parts – Before further use of the appli-ance, 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 condition 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 indicated elsewhere in this manual.
  WHEN USING AN ELECTRIC POWER HEAD:

• Do not leave appliance when plugged in. Unplug from outlet when not in use and before servicing.

• Hold the pruner attachment by insulated gripping surfaces only, because the saw chain may contact hidden wiring or its own cord. A saw chain contacting a “live” wire may make exposed metal parts of the pruner attachment “live” and could give the operator an electric shock.

• Keep power cord away from cutting area. During opera-tion, the power cord may be hidden in shrubs and can be accidentally cut by the saw chain.

• Do not allow to be used as a toy. Close attention is necessary when used by or near children.

• Use only as described in this manual. Use only manufacturer’s recommended attachments.

• Do not use with damaged cord or plug. If the appliance is not working as it should, has been dropped, damaged, left outdoors, or dropped into water, return it to a service center.

• Do not pull or carry by cord, use cord as a handle, close a door on cord, or pull cord around sharp edges or corners. Do not run appliance over cord. Keep cord away from heated surfaces.

• Do not unplug by pulling on cord. To unplug, grasp the plug, not the cord.

• Do not handle plug or appliances with wet hands.

• Do not put any object into openings. Do not use with any opening blocked; keep free of dust, lint, hair, and anything that may reduce airflow.

• Keep hair, loose clothing, fingers, and all parts of body away from openings and moving parts.

• Turn off all controls before unplugging.

PRUNER SAFETY RULES

• Keep all parts of the body away from the saw chain. Do not remove cut material or hold material to be cut when blades are moving. Make sure the switch is off when clearing jammed material. Saw chain continues to move after the switch is turned off. A moment of inattention while operating the extended-reach pruner may result in serious personal injury.
• Carry the extended-reach pruner by the handle with the saw chain stopped. When transporting or storing the extended-reach pruner, always fit the saw chain device cover. Proper handling of the extended-reach pruner will reduce possible personal injury from the saw chain.
• Hold the extended-reach pruner by insulated gripping surfaces only, because the saw chain may contact hidden wiring or its own cord. A saw chain contacting a “live” wire may make exposed metal parts of the extended-reach pruner “live” and could give the operator an electric shock.
• Keep cable away from cutting area. During operation, the cable may be hidden in shrubs and can be accidentally cut by the saw chain.
• Do not use the extended-reach pruner in bad weather conditions, especially when there is a risk of lightning. This decreases the risk of being struck by lightning.
• To reduce the risk of electrocution, never use near any electrical power lines. Contact with or use near power lines may cause serious injury or electric shock resulting in death.
• Always use two hands when operating the extended-reach pruner. Hold the extended-reach pruner with both hands to avoid loss of control.
• Always use head protection when operating the extended-reach pruner overhead. Falling debris can result in serious personal injury.
• Kickback is a dangerous reaction that can lead to serious injury. Kickback may occur when the moving chain contacts an object at the upper portion of the tip of the guide bar or when the wood closes in and pinches the chain in the cut. Contact at the upper portion of the tip of the guide bar can cause the chain to dig into the object and stop the chain for an instant. The result is a lightning-fast, reverse reaction that kicks the guide bar up and back toward the operator. If the chain is pinched along the top of the guide bar, the guide bar can be driven rapidly back toward the operator. Either of these reactions can cause loss of tool control which can result in serious injury. Do not rely exclusively upon the safety devices built into the tool. As a pruner user, you should take several steps to keep your cutting jobs free from accident or injury.
• With a basic understanding of kickback, you can reduce or eliminate the element of surprise. Sudden surprise contributes to accidents.
• Make sure 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, fence, or any other obstruction while you are operating the unit.
• Always cut with the engine or motor running at full speed. Fully squeeze the trigger and maintain a steady cutting speed.
• Follow the sharpening and maintenance instructions for the chain.
• Use only the replacement guide bars and low kickback chains specified for this unit.
• Do not force tool. Use the correct tool for your applica-tion. The correct tool will do the job better and safer at the rate for which it is designed.
• Do not use on a ladder or unstable support. Stable foot-ing on a solid surface enables better control of the tool in unexpected situations.
• Never let anyone use the tool who has not received adequate instructions in its proper use. This applies to rentals as well as privately owned units and also to the power head it is attached to.
• To protect yourself from electrocution, do not operate within 50 ft. of overhead electrical lines.
• To protect yourself from falling branches, do not stand directly under the branch or limb being cut. This unit should not be held at an angle over 60° from ground level.
• Keep the handles dry, clean, and free of oil or fuel mixture.
• Before you start the engine or motor, make sure the chain is not contacting any object.
• Shut off the engine or motor and make sure the cutting attachment has stopped before setting the unit down.
• DANGER! Serious injury or death from electrocution if power lines are contacted. Never use near any electri-cal source, wires, or powerlines. The unit has not been designed to provide protection from electric shock in the event of contact with overhead electric lines. Consult local regulations for safe distances from overhead electric power lines and ensure that the operating position is safe and secure before operating the pruner attachment.
• Wear face shield and hard hat to protect against falling debris. Always have a clear work area and retreat path. Be aware of limb/branch location to avoid falling limbs and debris. Keep bystanders 50 feet away when operating saw.
• Store Idle Appliance Indoors — When not in use, product should be stored indoors in a dry and high or locked up place—out of the reach of children.
• Save these instructions. Refer to them frequently and use them to instruct others who may use this tool. If you loan someone this tool, loan them these in-structions also to prevent misuse of the product and possible injury.

APPLICATIONS
You may use this product for the purposes listed below:

• Limbing
• Pruning

PREPARATION FOR CUTTING

• Wear non-slip gloves for maximum grip and protection.
• Maintain a proper grip on the unit whenever the engine or motor is running. Use your right hand to firmly grip the rear handle while your left hand has a firm grip on the front handle.
• Hold unit firmly with both hands. Always keep your left hand on the front handle and your right hand on the rear handle, so your body is to the left of the chain line. Never use a left-handed (cross-handed) grip, or any stance that places your body or arm across the chain line.
• Never stand directly under the limb you are cutting.
• Always wear shoulder strap for increased safety and to support the pruner.

POSITION FOR STARTING GAS POWERHEADS
See Figure 5.
Lay the pruner on the ground and ensure that no objects or obstructions are in the immediate vicinity. Make sure nothing can come in contact with the bar and chain, including dirt on the ground.

OPERATION

BASIC CUTTING PROCEDURE
See Figures 6 – 7.

• Follow these steps to prevent damage to tree or shrub bark. Do not use a back-and-forth sawing motion.Fully squeeze the trigger and allow the engine or motor to come to full speed just before entering the cut. Keep the engine or motor at full speed the entire time you are cutting.

• Make a shallow first cut (1/4 of limb diameter) on the underside of the limb close to the main limb or trunk.

• Make a second cut from the top side of the limb outboard from the first cut.

• Make a final cut close to trunk.
  NOTE: For second and final cuts (from top of limb or branch), hold front cutting guide against the limb being cut. This will help steady the limb and make it easier to cut. Allow chain to cut for you; exert only light downward pressure. If you force the cut, damage to the bar, chain, or engine or motor can result.

• Release the trigger as soon as the cut is completed, allowing the engine or motor to stop. If you run the pruner at full speed without a cutting load, unnecessary wear or damage can occur to the chain, bar, and engine or motor.
  Failure to follow proper cutting procedures will result in the bar and chain binding and becoming pinched or trapped in the limb. If this should happen:

• Stop the engine or motor.

• Remove the spark plug wire or disconnect from the power supply.

• Loosen the knob on the coupler.

• Depress the button on the shaft; twist and pull the shafts to separate the pruner from the power head.

• If the limb can be reached from the ground, lift the limb while holding the attachment. This should release the “pinch” and free the pruner.

• If the pruner is still trapped, call a professional for assistance.

• Check the chain tension frequently when operating the unit. Refer to Chain Tension in the Maintenance section of this manual.

LIMBING AND PRUNING
See Figures 8 – 9.

• This unit is designed for trimming small branches and limbs up to 6 in. in diameter. For best results, observe the following precautions:
• Plan the cut carefully. Be aware of the direction in which the branch will fall.
• Branches may fall in unexpected directions. Do not stand directly under the branch being cut.
• The most typical cutting application is to position the unit at an angle of 60° or less, depending on the specific situation. As the angle of the pruner shaft to ground increases, the difficulty of making the first cut (from the underside of limb) increases.
• Remove long branches in several stages.
• Cut lower branches first to allow the top branches more room to fall.
• Work slowly, keeping both hands on the tool with a firm grip. Maintain secure footing and balance.
• Keep the tree between you and the chain while limbing. Cut from side of tree opposite branch you are cutting.
• Do not cut from a ladder, rooftop, or other unstable support; this is extremely dangerous. Hire a professional for complex cutting situations.
• Do not make the flush cut next to the main limb or trunk until you have cut off the limb further out to reduce the weight. Following proper cutting procedures will prevent stripping the bark from the main member.
• Do not use the pruner for felling or bucking.
• To prevent electrocution, do not operate within 50 ft. of overhead electrical lines.
• Keep bystanders at least 50 ft. away.

MAINTENANCE

WARNING
Before inspecting, cleaning, or servicing the unit (except for carburetor adjustments), shut off engine or motor, wait for all moving parts to stop, and disconnect spark plug wire and move it away from spark plug or disconnect from power supply. Failure to follow these instructions can result in serious personal injury or property damage.

WARNING
Always wear eye protection with side shields marked to comply with ANSI Z87.1, as well as hearing and head protection, when operating this equipment. Failure to do so could result in objects being thrown into your eyes and other possible serious injuries.

WARNING
When servicing, use replacement parts that meet or exceed original product specifications. Use of any other parts could create a hazard or cause product damage.

NOTICE
Periodically inspect the entire product for damaged, missing, or loose parts such as screws, nuts, bolts, caps, etc. Tighten securely all fasteners and caps and do not operate this product until all missing or damaged parts are replaced. Please contact customer service or a qualified service center for assistance.

GENERAL MAINTENANCE

WARNING
To avoid possible serious injury, never touch or adjust the chain while the motor is running. The chain is very sharp; always wear protective gloves when performing maintenance to the chain.

REPLACING THE BAR AND CHAIN
See Figures 10 – 15.
Replacement Bar Part Number: 682802001
Replacement Chain Part Number: 682803001

WARNING:

• To avoid possible serious injury, stop engine or motor and remove the spark plug wire or disconnect from power supply before replacing the bar, chain, or performing any maintenance operation.

• Remove the bar nut and drivecase cover.

• The bar contains a bar stud slot that fits over the bar stud.

• The bar also contains a chain tensioning pin hole which fits over the chain tensioning pin.

• Place the bar onto the bar stud so that the chain tensioning pin fits into the chain tensioning pin hole.

• Fit the chain over the sprocket and into the bar groove. The cutters on the top of the bar should face toward the bar tip, in the direction of the chain rotation.

• Replace the drive case cover and reinstall the bar nut. Tighten the bar nut finger tight only; the bar must be free to move for tension adjustment.

• Remove all slack from chain by turning the chain tensioning screw clockwise, assuring that the chain seats into the bar groove during tensioning.

• Lift the tip of the bar up to check for sag. Release the tip of the bar, and turn the chain tensioning screw 1/2 turn clockwise. Repeat this process until sag does not exist.

• Hold the tip of the bar up and tighten the bar nut securely.
  Chain is correctly tensioned when there is no slack on the underside of the bar and the chain is snug, but can be turned by hand without binding.

• NOTE: If chain is too tight, it will not rotate. Loosen the bar nut slightly and turn the adjusting screw 1/4 turn counterclockwise. Lift the tip of the bar up and retighten bar nut.

WARNING
Check the chain tension frequently when operating the unit. Never touch or adjust the chain while the engine or motor is running. The chain is very sharp; always wear protective gloves when performing maintenance to the chain.

POWERHEAD IDLE SPEED ADJUSTMENT (GAS POWER HEADS ONLY)
If the chain turns at idle, the idle speed screw needs adjusting on your gas power head engine. Turn the idle speed screw counterclockwise to reduce the idle RPM and stop the chain movement. Refer to your power head Operator’s Manual for more details. If the chain still moves at idle speed, contact a service dealer for adjustment and discontinue use until the repair is made.

WARNING
The chain should never turn at idle when using a gas power head. Turn the idle speed screw “T” counter-clockwise to reduce the idle RPM and stop the chain, or contact a service dealer for adjustment and discontinue use until the repair is made. Serious personal injury could result from the chain turning at idle.

CHAIN TENSION
See Figures 16 – 17.
Stop the engine or motor and remove the spark plugwire or disconnect from power supply before setting thechain tension. Make sure the guide bar nut is loose tofinger tight, turn the chain tensioning screw clockwise totension the chain. Refer to Replacing the Bar and Chainfor additional information.

• A cold chain is correctly tensioned when there is no slack on the underside of the guide bar and the chain is snug, but can be turned by hand without binding.
• The chain must be re-tensioned whenever the flats on the drive links hang out of the bar groove.
• During normal operation, the temperature of the chain will increase. The drive links of a correctly tensioned warm chain will hang approximately .050 in. (1.25 mm) out of the bar groove.
  NOTE: New chains tend to stretch; check chain tension frequently and tension as required.

NOTICE :
A chain tensioned while warm may be too tight upon cooling. Check the “cold tension” before next use.

CHAIN OILER
See Figure 18.

• Use Premium Bar and Chain Lubricant. It is designed for chains and chain oilers and is formulated to perform over a wide temperature range with no dilution required.
• Remove the cap and carefully pour the bar and chain lubricant into the chain oiler tank.
• Replace the cap and tighten securely.
• Check and refill the chain oiler tank every hour when using an electric power head or every time the engine is fueled when using a gas power head.
  NOTE: Do not use dirty, used, or otherwise contaminated lubricants. Damage may occur to the oil pump, bar, or chain.

CHAIN MAINTENANCE
See Figure 19.
WARNING:
The chain is very sharp; always wear protective gloves when performing maintenance to the chain.
Use only the replacement low kickback chain specified for this unit.
For smooth and fast cutting, the chain needs to be maintained properly. The chain requires sharpening when the wood chips are small and powdery, the chain must be forced through the wood during cutting, or the chain cuts to one side. During maintenance of the chain, consider the following:

• Improper filing angle of the side plate can increase the risk of a severe kickback.
• Depth gauge (or raker clearance) setting determines the height the cutter enters the wood and the size of the wood chip that is removed. Too much clearance increases the potential for kickback. Too little clearance decreases the size of the wood chip thus decreasing the chain’s cut-ting ability.
• If cutter teeth have hit hard objects such as nails and stones, or have been abraded by mud or sand on the wood, have service dealer sharpen chain.

HOW TO SHARPEN THE CUTTERS
See Figures 20 – 22.

WARNING

• Improper chain sharpening increases the potential of kickback. Failure to replace or repair damaged chain can cause serious injury.
• Be careful to file all cutters to the specified angles and to the same length, as fast cutting can be obtained only when all cutters are uniform.
• Tighten the chain tension enough that the chain does not wobble. Do all of your filing at the mid-point of the bar. Wear gloves for protection.
• Use a 5/32 in. diameter round file and holder.
• Keep the file level with the top plate of the tooth. Do not let the file dip or rock.
• Using light but firm pressure, stroke towards the front corner of the tooth. Lift file away from the steel on each return stroke.
• Put a few firm strokes on every tooth. File all left-hand cutters in one direction. Then move to the other side and file the right hand cutters in the opposite direction. Occasionally remove filings from the file with a wire brush.

NOTICE
Dull or improperly sharpened chain can cause excessive engine or motor speed during cutting, which may result in severe engine or motor damage.

ATTACHING THE STORAGE HANGER
See Figure 23.
There are two ways to hang the attachment for storage.
To use the hanger cap, push in the button and place the hanger cap over the end of the attachment shaft. Slightly rotate the cap from side to side until the button locks into place.
The secondary hole in the attachment shaft can be used for hanging purposes as well.

STORING THE ATTACHMENT
See Figure 24.

• Clean the attachment thoroughly and lubricate before storing.
• Store the attachment indoors in a dry, well-ventilated place that is inaccessible to children
• Keep away from corrosive agents such as garden chemicals and de-icing salts.
