KICKBACK
a_WARNIN_: Avoidkickbackwhich canresultinseriousinjury.Kickbackis the
backward, upward orsudden forward motion of the guide bar occurring when the saw chain near the upper tip of the guide bar con- tacts any object such as a log or branch, or when the wood closes in and pinches the saw chain in the cut. Contacting aforeign ob- ject in the wood can also result in loss of chain saw control.
???RotationalKickbackcanoccurwhenthe moving chain contacts an object at the up- per tip of the guide bar. This contact can cause the chain to dig into the object, which stops the chain for an instant. The result is a lightning fast, reverse reaction which kicks the guide bar up and back to- ward the operator.
???
stopped. This sudden stopping of the chain results in a reversal of the chain force used to cut wood and causes the
sawto move inthe oppositedirectionofthe chain rotation. The saw is driven straight back toward the operator.
???
cause the operator to lose control of the saw.
Avoid
???Be extremely aware of situations or ob- structions that can cause material to pinch the top of or otherwise stop the chain.
???Do not cut more than one log at a time.
???Do not twist the saw as the bar is with-
drawn from an undercut when bucking.
Avoid
???Always begincuttingwiththeengineatfull speed and the saw housing against wood.
???Use wedges made of plastic or wood. Never use metal to hold the cut open.

REDUCE THE CHANCE OF
KICKBACK
???Recognize that kickback can happen. With a basic understanding of kickback, you can reduce the element of surprise which contributes to accidents.
???Never let the moving chain contact any ob- ject at the tip of the guide bar.
???Keep the working area free from obstruc- tions such as othertrees, branches, rocks,
fences, stumps, etc. Eliminate or avoid any obstruction that your saw chain could hit while you are cutting. When cutting a branch, do not let the guide bar contact branch or other objects around it.
???Keep your saw chain sharp and properly tensioned. A loose or dull chain can in-
crease the chance of kickback occurring. Follow manufacturer's chain sharpening and maintenanceinstructions. Checkten-
sion at regular intervals with the engine
stopped, never with the engine running. Make sure the bar clamp nuts are securely tightened after tensioning the chain.

KICKBACK SAFETY FEATURES
_I_WARNING: The following features
are included on your saw to help reduce the hazard of kickback; however, such features
will not totally eliminate this dangerous reac- tion. As a chain saw user, do not rely only on safety devices. You must follow all safety precautions, instructions, and maintenance in this manual to help avoid kickback and other forces which can result in serious
injury.

CHAIN TENSION (Including units with chain already installed)
NOTE: When adjusting chain tension, make sure the bar nuts are finger tight only. Attemptingto tensionthe chain when the bar nuts are tight can cause damage.
Checking the tension:
Use the screwdriver end of the combination screwdriver/wrench tool to move the chain around the bar. If the chain does not rotate, it
is too tight. Iftoo loose, the chain will sag be- low the bar.
Guide
Bar
Adjusting the tension:
Chain tension is very important. Chain stretches during use. This is especially true during the first few times you use your saw. Always check chain tension each time you use and refuel your saw.
You can adjust the chain tension by loosening the bar clamp nuts and turning the adjusting screw 1/4 of a tum while IAing up on the bar.
???If chain is too tight, turn adjusting screw 1/4 turn counterclockwise.

This engine is certified to operate on unleaded gasoline. Before operation, gasoline must be mixed with a good quality
gallon of unleaded gasoline). DO NOT USE automotive or boat oil. These oils will cause
enginedamage. When mixing fuel followthe instructions printed on the containe_ Always read and follow the safety rules listed under
HANDLE FUEL WITH CAUTION.
BAR AND CHAIN LUBRICATION
The bar and chain require continuous lubri- cation. Lubrication is provided by the auto- matic oiler system when the oil tank is kept filled. Lack of oil will quickly ruin the bar and chain. Too little oil will cause overheating shown by smoke coming from the chain and/ or discoloration of the bar.
In freezing weather oil will thicken, making it necessary to thin bar and chain oil with a small amount (5 to 10%) of#1 Diesel Fuel or

???Cut wood only. Do not cut metal, plastics, masonry,
???Stop the saw if the chain strikes a foreign object. Inspect the saw and repair parts as necessary.
???Keepthechainoutofdirtandsand. Evena small amountofdirt will quickly dull a chain and increase the possibility of kickback.
???Practice cutting a few small logs using the following techniques to get the "feel" of us- ing your saw before you begin a major sawing operation.
???Squeeze the throttle trigger and allow the engine to reach full speed before cutting.
???Begin cutting with the saw frame against the log.
???Keep the engine at full speed the en- tire time you are cutting.
???Allow the chain to cut for you. Exert only light downward pressure.
???Releasethe throttletrigger as soon as the cut is completed, allowing the en- gine to idle. If you run the saw at full throttle without a cutting load, unnec- essary wear can occur.
???To avoid losing control when cut is complete, do not put pressure on saw at end of cut.
???Stop the engine before setting the saw down after cutting.
TREE FELLING TECHNIQUES
_;IWARNING: Check for broken or
dead branches which can fall while cutting causing serious injury. Do not cut nearbuild- ings or electricalwires if you do not know the directionoftree fall, norcut at night sinceyou will not be ale to see well, nor during bad weathersuch as rain, snow, or strong winds, etc. If the tree makes contact with any utility line, the utility company should be notified immediately.
???Carefullyplan your sawingoperationin ad- vance.
???Cleartheworkarea. You needacleararea
all aroundthetreeso you can havesecure footing.
???The chain saw operator should keep on the uphill side of the terrain as the tree is likelyto rollor slidedownhillafterit is felled.
The chain brake must be checked several times daily. Hold the chain saw approximate- ly 14" (35 cm) above a stump or otherfirm ob- ject. Release your grip on the front handle and let the saw, by its own weight, rotate around the rear handle. When the tip of the bar hits the stump, the brake should activate.
??? Study the natural conditions that can cause
the tree to fall in a particular direction. Natural conditions that can cause a tree to
fall in a particular direction include:
???The wind direction and speed.
???The lean of the tree. The lean of a tree might not be apparent due to uneven or
slopingterrain. Use a plumb or level to de- termine the direction of tree lean.
???Weight and branches on one side.
???Surroundingtrees and obstacles.
Look for decay and rot. Ifthetrunk is rotted,
it can snap and fall toward the operator. Check for broken or dead branches which
can fall on you while cutting.
Make sure there is enough room for the tree to fall. Maintain a distance of
Remove dirt, stones, loose bark, nails, sta-
ples, and wire from the tree wherecuts are to be made.

sired direction of fall. After a felling cut is made on the opposite side of tree, the tree will tend to fall into the notch.
ing saw to remove buttress roots, keep saw chain from contacting ground to prevent dull- ing of the chain.
NOTCH CUT AND FELLING THE
TREE
???Make notch cut by cutting the top of the notch first. Cut through 1/3 of the diameter of the tree. Next complete the notch by cut- ting the bottom of the notch. See illustra- tion. Once the notch is cut remove the notch of wood from the tree.

???After removing the cutout of wood, make the felling cut on the opposite side of the notch. This is done by making a cut about two inches higher than the center of the notch. This will leave enough uncut wood between the felling cut and the notch to form a hinge. This hingewill help prevent the tree from falling in the wrong direction.

NOTE: Before felling cut is complete, use wedges to open the cut when necessary to controlthe directionof fall. To avoid kickback
and chain damage, use wood or plastic wedges, but never steel or iron wedges.
???Be alert to signs that the tree is ready to fall: cracking sounds, widening of the felling cut, or movement in the upper branches.
???As tree starts to fall, stop saw, put it down, and get away quickly on your planned re- treat path.
???DO NOT cut down a partially fallen tree with your saw. Be extremely cautious with partially fallen trees that may be poorly supported. When a tree doesn't fall com- pletely, set the saw aside and pull down the tree with a cable winch, block and tackle, or tractor.
CUTTING A FALLEN TREE (BUCKING)
Bucking is the term used for cutting a fallen tree to the desired log length.
WARNING: Do not stand on the log
being cut. Any portion can roll causing loss of footing and control. Do not stand downhill of the log being cut.
IMPORTANT POINTS
???Cut only one log at a time.
???Cut shattered wood very carefully; sharp pieces of wood could be flu ng toward oper- ator.
???Use a sawhorse to cut small logs. Never allow another person to hold the log while
cutting and never hold the log with your leg or foot.
???Do not cut in an area where logs, limbs, and roots are tangled. Drag the logs into a clear area before cutting by pulling out ex- posed and cleared logs first.
TYPES OF CUTTING USED FOR
BUCKING
DWARNIN_5:If saw becomes
pinched or hung in a log, don'ttry to force it out. You can lose control of the saw resulting in injury and/or damage to the saw. Stop the saw, drive a wedge of plastic or wood into the cut until the saw can be removed easily. Re- start the saw and carefully reenter the cut. Do not attempt to restart your saw when it is pinched or hung in a log.
Use a wedge to remove pinched saw
Turn saw OFF and use a plastic or wooden wedge to force cut open. Overcutting beginson thetop sideofthelog with the saw against the log. When overcut- ting use light downward pressure.
OvercuttingUndercutting
Undercuttinginvolves cutting on the under- side of the log with top of saw against the log. When undercutting use light upward pres- sure. Hold saw firmly and maintain control. The saw will tend to push back toward you.
_kWARNING: Neverturn saw upside down to undercut. The saw cannot be con- trolled in this position.
Always make your first cut on the compres- sion side ofthelog. Thecompression sideof the log is where the pressure of the log's weight is concentrated.

LIMBING AND PRUNING
Ka, WARNIN(5: Be alert for and guard
against kickback. Do not allow the moving chain to contact any other branches or ob- jects at the nose of the guide bar when limb-
ing or pruning. Allowing such contact can re- sult in serious injury.
4[_WARNING: Never climb into a tree
to limb or prune. Do not stand on ladders, platforms, a log, or in any position which can cause you to lose your balance or control of the saw.
IMPORTANT POINTS
???Work slowly, keeping both hands firmly gripped on the saw. Maintain secure foot- ing and balance.
???Watch out for springpoles. Use extreme caution when cutting small size limbs. Slender material may catch the saw chain and be whipped toward you or pull you off balance.
???Be alert for springback. Watch out for branches that are bent or under pressure. Avoid being struck by the branch or the saw when the tension in the wood fibers is released.
???Keep a clearwork area. Frequentlyclear
branches out of the way to avoid tripping over them.
LIMBING
???Alwayslimbatreeafteritiscutdown. Only then can limbing be done safely and prop- erly.
???Leave the larger limbs underneath the felled tree to support the tree as you work.
???Start at base of the felled tree and work to-
ward the top, cutting branches and limbs. Remove small limbs with one cut.
???Keep the tree between you and the chain. Cut from the side of the tree opposite the branch you are cutting.
???Remove larger, supporting branches with thecuttingtechniquesdescribed in BUCK-
ING WITHOUT A SUPPORT.
???Always use an overcut to cut small and freely hanging limbs. Undercutting could cause limbs to fall and pinch saw.
PRUNING
'A_WARNING: Limit pruning to limbs
shoulder height or below. Do not cut if branches are higher than your shoulde_ Get a professional to do the job.
???Make your first cut 1/3 of the way through the bottom of the limb.
