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 chain saw user,   you should take several steps to keep your cutting jobs   free from accident or injury.   BAR shOwN wIThOuT sAfE-T-TIp® NOsE GuARD fOR   ILLusTRATION puRpOsEs ONLy.   Fig. 1    Thefollowingprecautionsshould befollowed tomini-   KICKBACK   DANGER ZONE   mize kickback:   1. Always grip the saw firmly with both hands. Hold the   saw firmly with both hands when the unit is running.   Place your right hand on the rear handle and your left   hand on the front handle with your thumbs and fingers   encircling the chain saw handles. A firm grip together   with a stiff left arm will help you maintain control of   the saw if kickback occurs.   Fig. ꢀ   ꢀ. 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   that could be hit while you are operating the saw.   3. Always cut with the unit running at full speed. Fully   squeeze the throttle trigger and maintain a steady   cutting speed.   ꢁ. Use replacement parts such as low kickback chain,   SAFE-T-TIP® anti-kickbacknoseguards, chainbrakes   andspecialguidebarsthatreducetherisksassociated   with rotational kickback.   Useonlythereplacementguidebarsandlowkickback   chains specified by the manufacturer for the saw.   puLL    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.    Keep the SAFE-T-TIP® anti-kickback nose guard properly   mounted on the guide bar to prevent rotational kickback.    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.

Never attempt any kind of cutting where the SAFE-T-   TIP® would have to be removed from the bar tip.   NOTE: The size of the work area depends on the job   being performed as well as the size tree or work piece   involved. For example, felling a tree requires a larger work   area than making bucking cuts.   LOW KIcKBAcK SAW cHAIN   The rakers (depth gauges) ahead of each cutter can minimize   the force of a kickback reaction by preventing the cutters   from digging in too deeply at the kickback zone. Only use   replacement chain that is equivalent to original chain or has   been certified as low kickback chain per ANSI B175.1.    Neverstartcuttinguntilyouhaveaclearworkarea,secure   footing, and a planned retreat path from the falling tree.   Cluttered area invite injuries.    Do not expose the chain saw to rain.    Do not use the chain saw in damp or wet locations.   Low kickback saw chain is chain that has met the kickback   performance requirements of ANSI B175.1 - 1991 (Amer-   ican National Standard for Power Tools - Gasoline-Powered   Chain Saws-Safety Requirements) when tested on the rep-   resentative sample of chain saws below 3.8 c.i.d. specified   in ANSI B175.1 - 1991.    Do not use the chain saw near flammable liquids, gases,   or in any type of explosive atmosphere.    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 bal-   ance.   As saw chains are sharpened during their useful life, they   lose some of the low kickback qualities and extra caution   should be used.    When cutting a limb that is under tension, be alert for   spring back so that you will not be struck when the ten-   sion in the wood fibers is released.   GUIdE BARS   Generally, guide bars with small radius tips have somewhat   lower kickback potentials.    Do not force the chain saw. The job can be performed   better and safer at the rate for which it was intended.    Always use the right product for your application. The   chain saw should be used for cutting wood only. Never   use the chain saw to cut plastic, masonry or non-wood   building materials.   When making a replacement, be sure to order one of the   Ryobi bars listed for the saw in this operator's manual. The   proper size SAFE-T-TIP® nose guard comes installed on the   bar. Use only guide bars that have a provision for mounting   the SAFE-T-TIP®.    Do not use the chain saw for purposes not intended.    Store idle chain saw when not in use. Chain saw should   be stored in a dry and high or locked area out of the reach   of children. When storing chain saw, remove battery and   placethescabbardonthebarandchainorstorethechain   saw in a carry case.   sAfE-T-TIp®    Remove the battery pack from the chain saw before   cleaning, servicing, storing, removing material from the   unit, changing accessories such as the bar and chain, or   when not in use.   Fig. ꢁ   5 Download from Www.Somanuals.com.

Properly dispose of a dropped or damaged   battery immediately.   BATTERY SAFETY    Battery operated units do not have to be plugged into an   electrical outlet; therefore, they are always in operating   condition. Be aware of possible hazards even when unit   is not operating.    Batteries can explode in the presence of a source of ig-   nition, such as a pilot light. To reduce the risk of serious   personal injury, never use any cordless product in the   presence of open flame. An exploded battery pack can   propel debris and chemicals. If exposed, flush with water   immediately.    Remove the battery pack from the chain saw before   cleaning, servicing, storing, removing material from the   unit, changing accessories such as the bar and chain, or   when not in use.    Do not charge unit in a damp or wet location. Following   this rule will reduce the risk of electric shock.    A battery pack must be recharged only with the speci-   fied charger for the battery pack. A charger that may be   suitable for one type of battery pack may create a risk   of fire when used with another battery pack. Use battery   pack only with charger listed.    For best results, your battery unit should be charged in   a location where the temperature is more than 50°F but   less than 100°F. Do not store outside or in vehicles.    Under extreme usage or temperature conditions, battery   pack leakage may occur. If liquid comes in contact with   your skin, wash immediately with soap and water, then   neutralize with lemon juice or vinegar. If liquid gets into   your eyes, flush them with clean water for at least 10   minutes, then seek immediate medical attention.   MOdEL   BATTERY PAcK   cHARGER (P113)   (P104 Li-ion)   130ꢁꢀ9001, 130ꢁꢀ900ꢀ   130155001   1ꢁ0501001   1ꢁ0501005   P5ꢁ0   P5ꢁ0A   P5ꢁ0B   (P100 Ni-cd)   130ꢀ5500ꢁ, 130ꢀꢀꢁ0ꢀ8    Do not dispose of batteries in a fire.

See Figure 13.   sAfE   RETREAT   ZONE   135°   pLANNED   LINE Of fALL   45°   45°   90°    Before felling is started, consider the force and direction   of the wind, the lean and balance of the tree, and the lo-   cation of large limbs. These things influence the direction   in which the tree will fall. Do not try to fell a tree along a   line different from its natural line of fall.   135°   sAfE   RETREAT   ZONE    The chain saw operator should keep on the uphill side   of the terrain as the tree is likely to roll or slide downhill   after it is felled.   Fig. 13    Remove dirt, stones, loose bark, nails, staples, and wire   from the tree where felling cuts are to be made.    Notched Undercut. 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 wood off the saw,   always make the lower cut of the notch before the upper   cut.

See Figures 14 - 15.    Never cut through to the notch. Always leave a band of   wood between the notch and backcut (approximately   ꢀ in. 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. See Figures 14 - 15.    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. Then insert soft wooden or plastic wedges   into the cut so they do not touch the chain. The wedges   can be driven in, little by little, to help jack the tree over.   See Figure 16.   NOTCh   BACK CuT   NOTE: When bucking or felling with a wedge, it may   be necessary to remove the SAFE-T-TIP® anti-kickback   device to allow the bar to be drawn through the cut.   After the cut is complete, the tip should be reinstalled   immediately.   hINGE   Fig. 15    As tree starts to fall, stop the chain saw 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.   WARNING:   Never cut through to the notch when making a backcut.   The hinge controls the fall of the tree, this is the section   of wood between the notch and backcut.   wEDGE   Fig. 16   KICKBACK   BUcKING   See Figures 17 - 20.   Bucking is the term used for cutting a fallen tree to the de-   sired log length.    Always make sure your footing is secure and your weight   is distributed evenly on both feet.    Cut only one log at a time.    Support small logs on a saw horse or another log while   Fig. 17   bucking.    Keep a clear cutting area. Make sure that no objects can   contact the guide bar nose and chain during cutting, this   can cause kickback.

Then make the finishing   cut by overbucking to meet the first cut.   As the log is being cut, it will tend to bend. The saw can   become pinched or hung in the log if you make the first cut   deeper than 1/3 of the diameter of the log.   1sT CuT   1/3 DIA   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 as shown in figure 18. When “cutting through,”   to maintain complete control of the chain saw, release the   cutting pressure near the end of the cut without relaxing your   grip on the chain saw handles. Do not let the chain contact   the ground. After completing the cut, wait for the saw chain   to stop before you move the chain saw. Always stop the   motor before moving from tree to tree.   LOG suppORTED AT BOTh ENDs:   LOAD   1sT CuT 1/3 DIA   TYPES OF cUTTING USEd   See Figure 20.   OVERBUcKING   Begin on the top side of the log with the bottom of the saw   against the log; exert light pressure downward. Note that   the saw will tend to pull away from you.   fINIshING CuT   OvERBuCKING   Fig. 19   UNdERBUcKING   Begin on the under side of the log with the top of the saw   against the log; exert light pressure upward. During under-   bucking, the saw will tend to push back at you. Be pre-   pared for this reaction and hold the saw firmly to maintain   control.   WARNING:   Never climb into a tree to limb or prune.
