IMPORTANT SAFETY INSTRUCTIONS G. Carry the chain saw by the front handle with the chain saw switched off and away from your body. When transporting or storing the chain saw always fit the guide bar cover.Proper handling of the chain saw will reduce the likelihood of accidental contact with the moving saw chain. H. Follow instructions for lubricating, chain tensioning, and changing accessories.Improperly tensioned or lubricated chain may either break or increase the chance for kickback. I.
general SAFETY RULES KICKBACK (See Fig. 1 - 2.) WA R N I N G 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 that kicks the guide bar up and back toward the operator.
general SAFETY RULES • Push and Pull — This reaction force is always opposite to the direction the chain is moving where contact is made with the wood. Thus, the operator must be ready to control the PULL when cutting on the bottom edge of the bar, and the PUSH when cutting along the top edge. (See Fig. 3) PULL PUSH Fig.

operation Starting the chain saw: • Make sure chain tension is at desired setting. Refer to Adjusting the Chain Tension in the Maintenance section of this manual. • Make sure the chain cover lock knob is tight to the chain cover. • Make sure no objects or obstructions are in immediate vicinity which could come into contact with the bar and chain. • Press and hold the switch lock. This makes the trigger switch operational.
operation PREPARING FOR CUTTING PROPER GRIP ON HANDLES (See Fig. 9) See General Safety Rules for appropriate safety equipment. • Wear non-slip gloves for maximum grip and protection. • Hold the saw firmly with both hands. Always keep your left hand on the front handle and your right hand on the rear handle so that your body is to the left of the chain line. • Maintain a proper grip on the saw whenever the motor is running. The fingers should encircle the handle, with the thumb wrapped under the handlebar.
operation PROPER CUTTING STANCE (See Fig. 10) • Balance your weight with both feet on solid ground. • Keep left arm with elbow locked in a “straight arm” position to withstand any kickback force. • Keep your body to the left of the chain line. • Keep your thumb on underside of handlebar. BASIC OPERATING/CUTTING PROCEDURES 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.
operation WORK AREA PRECAUTIONS (See Fig. 11) • Cut only wood or materials made from wood; no sheet metal, no plastics, no masonry, no nonwooden building materials. • Never allow children to operate the saw. Allow no person to use this chainsaw who has not read this Owner's Manual or received adequate instructions for the safe and proper use of this chainsaw. • Keep everyone – helpers, bystanders, children, and animals – a SAFE DISTANCE from the cutting area.
operation PLANNED LINE OF FALL PLANNED LINE OF FALL PATH OF SAFE RETREAT 45° 90° 45° 135° 90° 135° FROM PLANNED LINE OF FALL 135° PATH OF SAFE RETREAT Fig. 12 • 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.
operation • Consider the force and direction of the wind, the lean and balance of the tree, and the location 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. • 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 trunk in the side of the tree.
operation REMOVING BUTTRESS ROOTS (See Fig. 14) A buttress root is a large root extending from the trunk of the tree above the ground. Remove large buttress roots prior to felling. Make the horizontal cut into the buttress first, followed by the vertical cut. Remove the resulting loose section from the work area. Follow the correct tree felling procedure as stated in Proper Procedure For Tree Felling after you have removed the large buttress roots. BUCKING (See Fig.
operation BUCKING WITH A WEDGE (See Fig. 16) If the wood diameter is large enough for you to insert a soft bucking wedge without touching the chain, you should use the wedge to hold the cut open to prevent pinching. BUCKING LOGS UNDER STRESS (See Fig. 17) Make the first bucking cut 1/3 of the way through the log, and finish with a 2/3 cut on the opposite side. As you cut the log, it will tend to bend.
operation LIMBING (See Fig. 20) Limbing is removing branches from a fallen tree. • Work slowly, keeping both hands on the chainsaw with a firm grip. Always make sure your footing is secure and your weight is distributed evenly on both feet. • Leave the larger support limbs under the tree to keep the tree off the ground while cutting. • Limbs should be cut one at a time. Remove the cut limbs from the work area often to help keep the work area clean and safe.
operation LOAD SECOND CUT FIRST CUT 1/3 DIA CUT LIMBS ONE AT A TIME AND LEAVE SUPPORT LIMBS UNDER TREE UNTIL LOG IS CUT Fig. 20 FINISHING CUT Fig. 21 CUTTING SPRINGPOLES (See Fig. 22) A springpole is any log, branch, rooted stump, or sapling that is bent under tension by other wood, so that it springs back if the wood holding it is cut or removed. On a fallen tree, a rooted stump has a high potential of springing back to the upright position during the bucking cut to separate the log from the stump.
maintenance WA R N I N G When servicing, use only identical GreenWorks™ replacement parts. Use of any other parts may create a hazard or cause product damage. WA R N I N G Always wear safety goggles or safety glasses with side shields during power tool operation or when blowing dust. If operation is dusty, also wear a dust mask. GENERAL MAINTENANCE Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to damage from various types of commercial solvents.
maintenance REPLACING THE GUIDE BAR AND CHAIN (See Fig. 23 - 28.) D A N G E R Never start the motor before installing the guide bar, chain, chain cover, and chain cover lock knob. Without all these parts in place, the clutch can fly off or explode, exposing the user to possible serious injury. WA R N I N G To avoid serious personal injury, read and understand all the safety instructions in this section. WA R N I N G Before performing any maintenance, make sure the tool is unplugged from the power supply.

maintenance CUTTERS CHAIN ROTATION CHAIN DRIVE LINKS Fig. 27 Fig. 25 BAR GROOVE CHAIN DRIVE LINKS Fig. 26 Fig. 28 • Release the tip of the guide bar, and turn the chain tensioning knob 1/2 turn clockwise. • Hold the tip of the guide bar up and tighten the chain cover lock knob. The chain is correctly tensioned when there is no sag on the underside of the guide bar, and when the chain is snug, but can be turned by hand without binding. NOTE: If chain is too tight, it will not rotate.
maintenance • Turn the chain tensioning knob clockwise to tension the chain. NOTE: A cold chain is correctly tensioned when there is no slack on the underside of the guide bar, the chain is snug, and it can be turned by hand without binding. • Rotate the chain cover lock knob clockwise to secure. Retension the chain whenever the flats on the drive links hang out of the bar groove. NOTE: During normal saw operation, the temperature of the chain increases.
maintenance C A U T I O N Make sure the chainsaw is disconnected from the power supply before you work on the saw. CHAIN MAINTENANCE (See Fig. 31) Use only a low-kickback chain on this saw. This fast-cutting chain provides kickback reduction when properly maintained. For smooth and fast cutting, maintain the chain 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.
maintenance SHARPENING THE CUTTERS (See Fig. 32 - 35.) Be careful to file all cutters to the specified angles and to the same length, because fast cutting can only be obtained when all cutters are uniform. C A U T I O N Make sure the chainsaw is disconnected from the power supply before you work on the saw. WA R N I N G The saw chain is very sharp. Always wear protective gloves when performing maintenance involving the chain to prevent serious personal injury. • Tension the chain prior to sharpening.
maintenance C A U T I O N A dull or improperly sharpened chain can cause excessive motor speed during cutting, which may result in severe motor damage. WA R N I N G Improper chain sharpening increases the potential for kickback. WA R N I N G Failure to replace or repair a damaged chain can cause serious injury. TOP PLATE FILING ANGLE • CORRECT 30° – file holders are marked with guide marks to align file properly to produce correct top plate angle. • LESS THAN 30° – for cross cutting.
maintenance MAINTAINING DEPTH GAUGE CLEARANCE • Maintain the depth gauge at a clearance of .025" (.6 mm). Use a depth gauge tool for checking the depth gauge clearances. • Every time the chain is filed, check the depth gauge clearance. • Use a flat file and a depth gauge jointer to lower all gauges uniformly. Use a .025" (.6 mm) depth gauge jointer. After lowering each depth gauge, restore original shape by rounding the front. Be careful not to damage adjoining drive links with the edge of the file.
maintenance STORING THE PRODUCT • Clean all foreign material from the product. Store it in a well-ventilated place that is inaccessible to children. Keep away from corrosive agents such as garden chemicals and deicing salts. • Always place the scabbard on the bar and chain before storing or transporting the chainsaw • Use caution to avoid the sharp teeth of the chain Quick reference of chain & bar assembly 1.
