GENERAL SAFETY RULES WA R N I N G Read and understand all instructions before using this product. Failure to follow all instructions listed below may result in electric shock, fire, and/or serious personal injury. • Do not start cutting until you have a clear work area, secure footing, and a planned retreat path from the falling tree. Cluttered areas invite accidents. • Keep all children, bystanders, visitors, and animals out of the work area while starting or cutting with the chain saw.
GENERAL SAFETY RULES • Do not dispose of batteries in a fire, the cell may explode, check with local codes for possible special disposal instruction. • Do not open or mutilate the batteries; released electrolyte is corrosive and may cause damage to the eyes or skin, and may be toxic if swallowed. • Exercise care in handling battery in order not to short the battery with conducting material such as rings, bracelets and keys. The battery or conductor may overheat and cause burns.
GENERAL SAFETY RULES • Use only Yardworks 40 V batteries. • Do not use the chain saw for purposes not intended. • Store 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. • 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 instructions also. • Always use two hands when operating the chain saw.
GENERAL SAFETY RULES 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 which kicks the guide bar up and back toward the operator.
GENERAL SAFETY RULES W A R N I N G (PROPOSITION 65) Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are: • Lead from lead-based paints • Crystalline silica from bricks and cement and other masonry products, and • Arsenic and chromium from chemically treated lumber.
GENERAL SAFETY RULES • 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.

ASSEMBLY INSTRUCTION BATTERY TO INSTALL THE BATTERY: 1. Align the battery with the battery opening. 2. Insert the battery into the battery opening until the battery release button locks into place. 3. Push down on the battery until it locks into place. You should hear a “click” once it is installed. TO REMOVE THE BATTERY: 1. Press the battery release button on the chain saw. This will cause the battery to raise out of the tool slightly. 2. Grasp the chain saw firmly and pull the battery out of the handle.
OPERATION STARTING AND STOPPING THE CHAIN SAW A. To start the chain saw: • Make sure chain tension is at desired setting. Refer to adjusting the chain tension in the Care and 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 the immediate vicinity which could come in contact with the bar and chain. • Fit the battery into the chain saw. • Press in the safety lock. This makes the trigger switch operational.
OPERATION PREPARING FOR CUTTING A. Proper grip on handles 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 and the thumb is wrapped under the handlebar.
OPERATION PROPER CUTTING STANCE • 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 front handle. 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. • Take the proper stance in front of the wood.
OPERATION REMOVING BUTTRESS ROOTS 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.
OPERATION • Felling Backcut. As the felling cut gets close to the hinge, the tree should begin to fall. If there is any chance the tree may not fall in the desired direction or it may rock back and bind the saw chain, stop cutting before the felling cut is complete and use wedges of wood, plastic or aluminum to open the cut and drop the tree along its desired line of fall. Make the backcut level and horizontal, and at a minimum of 2 in. (5 cm) above the horizontal cut of the notch.
OPERATION BUCKING Bucking is the term used for cutting a fallen tree to the desired 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 bucking. • Keep a clear cutting area. Make sure that no objects can contact the guide bar nose and chain during cutting as this can cause kickback. Refer to Kickback earlier in this manual.
OPERATION BUCKING LOGS UNDER STRESS When the log is supported on one end, cut 1/3 the diameter from the underside. Then make the finished cut by overbucking to meet the first cut. When the log is supported on both ends, cut 1/3 of the diameter from the top overback. Then make the finished cut by under bucking the lower 2/3 to meet the first cut.
OPERATION LIMBING Limbing is removing branches from a fallen tree. • Work slowly, keeping both hands on the chain saw 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 When bucking on a slope always stand on the uphill side of the log. when cutting through to maintain complete control release the cutting pressure near the end of the cut without relaxing your grip on the chainsaw handle. Don’t 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.
MAINTENANCE GENERAL MAINTENANCE Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to damage from various types of commercial solvents and may be damaged by their use. Use clean cloths to remove dirt, dust, lubricant, grease, etc., firmly to maintain control. • Do not at any time let brake fluids, gasoline, petroleum-based products, penetrating oils, etc., come in contact with plastic parts.
MAINTENANCE REPLACING THE GUIDE BAR AND CHAIN • • • • Remove the battery from the chain saw. Remove the supplied wrench from the rear handle. Unscrew the sprocket cover tighten nuts from chain cover by rotating them counterclockwise with the wrench and remove the chain cover. Remove the bar and chain from the mounting surface.
MAINTENANCE • • Lay out the new saw chain in a loop and straighten any kinks. The cutters should face in the direction of chain rotation. If they face backwards, turn the loop over. Place the chain drive links into the bar groove. Cutters Chain Rotation Chain Drive Links NOTE: Make certain of direction of the chain. • Position the chain so there is a loop at the back of the bar. • Hold the chain in position on the bar and place the loop around the sprocket.
MAINTENANCE • Turn the chain tensioner screw by the wrench clockwise until the saw chain is properly tensioned. The guide bar must then be pushed upwards, check chain tension again, do not tension the chain too tight. • After the chain is well-tensioned, tighten the nuts again. NOTE: The saw chain is properly tensioned if, in the middle of the guide bar, it can be lifted 3mm to 4mm from the edge of the guide bar. NOTE: If the chain is too tight, it will not rotate.
MAINTENANCE ADJUSTING THE CHAIN TENSION • Rotate the chain cover lock knob clockwise to secure. Re-tension the chain whenever the flats on the drive links hang out of the bar groove. Flats on drive links WA R N I N G Never touch or adjust the chain while the motor is running. The chain saw is very sharp. Always wear protective gloves when performing maintenance on the chain. WA R N I N G A chain tensioned while warm may be too tight upon cooling. Check the “cold tension” before next use.
MAINTENANCE CHAIN MAINTENANCE 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 • 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. • Tension the chain prior to sharpening. Refer to Adjusting The Chain Tension. • Use a 5/32 in. (4 mm) diameter round file and holder. Do all of your filing at the midpoint of the bar. • Keep the file level with a top plate of the tooth. Do not let the file dip or rock. • Using light but firm pressure.
MAINTENANCE 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. • MORE THAN 30° – feathered edge dulls quickly. Top Place Filling Angle Side Plate Filling Angle Correct Incorrect Hook Backward Slope Raker (Depth Gauge) Clearance 1/32” (0.6 mm) Incorrect SIDE PLATE ANGLE • Correct 80° – Produced automatically if you use the correct diameter file in the file holder.
MAINTENANCE SIDE PLATE ANGLE • Maintain the depth gauge at a clearance of 1/32 in. (0.6 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 1/32 in. • (0.6 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.
