all instructions listed below may result in electric shock,

Save all warnings and in-

structions for future reference. The term “power tool”

in the warnings refers to your mains-operated (corded)

power tool or battery-operated (cordless) power tool.

WORK AREA SAFETY

Keep work area clean and well lit. Cluttered or dark areas invite accidents. Do not operate power tools in explosive atmo-

liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes. Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
ELECTRICAL SAFETY
Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools.

of electric shock. Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock. Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock. When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock. If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of a RCD reduces the risk of electric shock.
PERSONAL SAFETY
Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under
A moment of inattention while operating power tools may result in serious personal injury. Use personal protective equipment. Always wear eye protection. Protective equipment such as a dust mask, non-skid safety shoes, hard hat or hearing protection used for appropriate conditions will reduce personal injuries.
Prevent unintentional starting. Ensure the switch

Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations. Dress properly. Do not wear loose clothing or jewellery. Keep your hair and clothing away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards. Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.
POWER TOOL USE AND CARE
Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed. Do not use the power tool if the switch does not
Any power tool that cannot be controlled with the switch is dangerous and must be repaired. Disconnect the plug from the power source and/ or remove the battery pack, if detachable, from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally. Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users. Maintain power tools and accessories. Check for misalignment or binding of moving parts, breakage
the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

Always be aware of what you are doing when using the chainsaw. Use common sense. Do not operate the chainsaw when you are tired, ill, or under the
Keep all parts of your body away from the saw chain when the unit is running.
Never let anyone use your chainsaw who has not received adequate instructions in its proper use. This applies to rentals as well as privately owned saws. Before you start the unit, make sure the saw chain is not contacting any object. Stop the chainsaw before setting it down. Maintain the unit with care. Keep the cutting edge sharp and clean for best performance and to reduce the risk of injury. Follow instructions for lubricating and changing accessories. Keep handles dry, clean, and free from oil and grease. Greasy, oily handles are slippery causing loss of control. Do not operate a chainsaw with one hand! Use a firm grip with thumbs and fingers encircling the chainsaw handles. Serious injury to the operator, helpers, bystanders, or any combination of these persons may result from one-handed operation. A chainsaw is intended for two-handed use. Do not operate a chainsaw that is damaged, improperly adjusted, or not completely and securely assembled. Chain should slow to a stop when the switch trigger is released. If the chain continues to turn after the switch trigger has been released, have the unit serviced by an authorised service centre. Always maintain a proper stance. Do not adapt your powerhead to a bow guide or use it to power any attachments or devices not listed for the saw. Do not cut vines and/or small underbrush. Do not operate a chainsaw in a tree, on a ladder,

Always use the right product for your application.

The chainsaw should be used for cutting wood only.

Never use the chainsaw to cut plastic, masonry or

non-wood building materials. Store chainsaw when not in use. Chainsaw should

be stored in a dry and high or locked area out of the

reach of children. When storing chainsaw place the

handle and your right hand on the rear handle so that your body is to the left of the guide bar. Do not hold chainsaw by front hand/chain brake. Keep elbow of left arm locked so that left arm is straight to withstand kickback. Never use a cross-handed grip (left hand on the rear handles and right hand on the front handle). Never allow any part of your body to be in line with the guide bar when operating the chainsaw. Never operate while in a tree, in any awkward position or on a ladder or other unstable surface. You may loose control of saw causing severe injury. Never fell a tree or cut a log or limb that has a diameter greater that the length of the guide bar. Only properly trained professionals should perform these cuts. Performing these types of cuts can cause an accident and result in death or serious personal injury. Keep the chainsaw running at full speed the entire time you are cutting. Allow the chain to cut for you. Exert only light pressure. Do not put pressure on chainsaw at end of cut. When not in use always have the chain brake engaged and battery removed. Do not use any attachments or accessories not recommended by the manufacturer. The use of attachments or accessories not recommended
can result in serious personal injury.

DANGER Never cut near power lines, electric
cords, or other electric sources. If bar and chain jams on any electrical cord or line, DO NOT TOUCH THE BAR OR CHAIN! THEY CAN BECOME ELECTRICALLY LIVE AND VERY DANGEROUS. Continue to hold the chainsaw by the insulated rear handle or lay it down and away from you in a safe manner. Disconnect the electrical service to the damaged line or cord before attempting to free the bar and chain from the line or cord. Contact with the bar, chain, other conductive parts of the chainsaw, or live electric cords or lines will result in death by electrocution, electric shock, or serious personal injury.

Kickback

WARNING

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 saw

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 which

kicks the guide bar up and back toward the operator.

If the saw 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 saw control which can result in serious injury. Do

not rely exclusively upon the safety devices built into

the saw. As a chainsaw user, you should take sev-

eral 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. Keep proper footing and balance at all times.
Do not cut above shoulder height or overreach when cutting. Follow the sharpening and maintenance instructions for the saw chain. Push and Pull – This reaction force is always opposite to the direction the chain is moving where wood contact is made. Thus, the operator must be ready to control the PULL when cutting on the bottom edge of the bar, and PUSH when cutting along the top edge.

Proper Cutting Stance

WARNING

Always use the stance described

proper in this

cutting section.

Never kneel when using the chainsaw, except

when felling a tree. Kneeling could result in loss

of stability and control of the chainsaw, resulting

in serious personal injury.

Weight should be balanced with both feet on

solid ground.

Keep left arm with elbow locked in a “straight

arm” position to withstand any kickback force.

Your body should always be to the left of the

chain line.

Thumb should be on underside of handlebar.

Work Area Precautions Cut only wood or materials made from wood, no sheet metal, no plastics, no masonry, no non-wood building materials. Never allow children to operate the saw. Allow no person to use this chainsaw who has not read this Operator’s Manual or received adequate instructions for the safe and proper use of this chainsaw. When felling a tree, keep everyone – helpers, bystanders, children, and animals – a safe distance from the cutting area. During felling operations, the safe distance should be a least twice the height of the largest trees in the felling area. During bucking operations, keep a minimum distance of 4.5 metres between workers. Trees should not be felled in a manner that would endanger any person, strike any utility line or cause any property damage. If the tree does make contact with any utility line, the utility

Basic Cutting Procedure Practice cutting a few small logs using the following technique to get the “feel” of using the saw before you begin a major sawing operation. Take the proper stance in front of the wood with
Squeeze the switch trigger and let the chain accelerate to full speed before entering the cut. Begin cutting with the saw against the log. Keep the unit running the entire time you are cutting, maintain a steady speed. Allow the chain to cut for you; exert only light downward pressure. If you force the cut, damage to the bar, chain, or unit can result. Release the switch trigger as soon as the cut is completed, allowing the chain to stop. If you run the saw without a cutting load, unnecessary wear can occur to the chain, bar, and unit. Do not put pressure on the saw at the end of cut.
Recommendation that the first-time user should, as a minimum practice, cut logs on a saw-horse or cradle.

Do not fell trees near electrical wires or buildings. Leave this operation for professionals. Cut only when visibility and light are adequate for you to see clearly.
Check work area for hazards such as bees, small animals, snakes, etc., that may live in trees or brush.

Felling Trees

Hazardous Conditions

WARNING

Do not fell high wind

trees during periods of or heavy precipitation.

Wait until the hazardous weather has ended.

Closely check for broken or dead branches, which could fall while cutting and do not cut near buildings or electrical wires if you do not know the direction of tree fall. Do not cut at night or during bad weather conditions, such as rain, snow, or strong winds, which can reduce visibility and control of the chainsaw. If the tree you are felling makes contact with any utility line, you should discontinue use of the chainsaw and immediately notify the utility company. Failure to follow these instructions could result in death or serious personal injury.

When felling (cutting down) a tree, it is important that you follow these warnings and instructions to prevent possible serious injury. Do not cut down trees having an extreme lean or large trees with rotten limbs, loose bark, or hollow trunks. Have these trees pushed or dragged down with heavy equipment, then cut them up. Do not cut trees near electrical wires or buildings. Check the tree for damaged or dead branches that could fall and hit you during felling. Periodically glance at the top of the tree during the backcut to assure the tree is going to fall in the desired direction. If the tree starts to fall in the wrong direction, or if the saw gets caught or hung up during the fall, leave the saw and save yourself! Felling a tree – When bucking and felling operations are being performed by two or more persons at the same time, the felling operation should be separated from the bucking operation by a distance of at least twice the height of the tree being felled.

Before any cuts are started, pick your escape route (or routes in case the intended route is blocked); clear the immediate area around the tree and make sure there are no obstructions in your planned path of retreat. Clear paths of safe retreat should extend back and diagonally (45°) to the rear of the planned line of fall. When the tree begins to fall, you should retreat away from the direction of fall along a retreat path and at least 6m away from the trunk in case it kicks back over the stump. Before felling is started, consider the force and direction of the wind, the lean and balance of the tree, and the location of large limbs. These things

Back Cut

Notch

Felling Backcut (the final cut in a tree felling operation made on the opposite side of the tree from the notching undercut). The backcut is always made level and horizontal, and at a minimum of 50 mm above the horizontal cut of the notch. Never cut through to the notch. Always leave a band of wood between the notch and backcut (approximately 50 mm or 1/10 the diameter of the tree). This is called “hinge” or “hingewood.” It controls the fall of the tree and prevents slipping or twisting or shoot-back of the tree off the stump. On large diameter trees, stop the back cut before it is deep enough for the tree to either fall or settle back on the stump.

Remove dirt, stones, loose bark, nails, staples, and wire from the tree where felling cuts are to be made. Notched Undercut (a notch cut in a tree that directs the tree’s fall). Cut a notch about 1/3 the diameter of the tree, perpendicular to the direction of fall. Make the cuts of the notch so they intersect at a right angle to the line of fall. This notch should be cleaned out to leave a straight line. To keep the weight of the
notch before the upper cut.

As tree starts to fall, stop the chainsaw and put it down immediately. Retreat along the cleared path, but watch the action in case something falls your way. Be alert for overhead limbs or branches that may fall and watch your footing.

When bucking on a slope, always stand on the uphill side of the log. To maintain complete control of the chainsaw when cutting through the log, release the cutting pressure near the end of the cut without relaxing your grip on the chainsaw handles. Do not let the chain contact the ground. After completing the cut, wait for the saw chain to stop before you move the chainsaw. Always stop the motor before moving from tree to tree.

Give special attention to logs under stress to prevent the bar and chain from pinching. When bucking on a slope, always stand on the uphill side of the log. When “cutting through,” to maintain complete control of the chainsaw, release the cutting pressure near the end of the cut without relaxing your grip on the chainsaw handles. Do not let the chain contact the ground. After completing the cut, wait for the saw chain to stop before you move the chainsaw. Always stop the motor before moving
