W A R N I N G When use a electric chainsaw, basic safety preccation should be always followed to reduce the risk of fire, electric shock, and injury to persons, including the following. 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.
SAFETY INFORMATION a. use only the following type and size batteries (GMAX 4Ah & 2Ah Battery / # 29472 & 29462) b. do not dispose of batteries in a fire, the cell may explode,check with local codes for possible special desposal instruction. c. do not open or mutilate the batteries, released electrolyte is corrosive and may cause damage to the eyes or skin, if may be toxic if swallowed. d.
SAFETY INFORMATION WA R N I N G 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.
SAFETY INFORMATION KICKBACK (See Figure 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 which kicks the guide bar up and back toward the operator.
SAFETY INFORMATION 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. (See Figure 3) PULL PUSH Fig. 3 UNDERSTANDING YOUR CHAIN SAW SAFETY DEVICES (See Figure 4) Fig. 4 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 B175.1.

OPERATING YOUR CHAIN SAW BASIC OPERATING/CUTTING PROCEDURES Practice cutting a few small logs using the following technique to get the “feel” of using the saw % < Take the proper stance in front of the wood with the saw idling. Press the switch lock and squeeze the switch trigger then release switch lock and let the chain accelerate to full speed before entering the cut. Begin cutting with the saw against the log.
OPERATING YOUR CHAIN SAW FELLING TREES HAZARDOUS CONDITIONS WA R N I N G Do not fell trees during periods of high wind or heavy precipitation. Wait until the hazardous weather has ended. When felling a tree, it is important that you heed the following warnings to prevent possible % 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.
OPERATING YOUR CHAIN SAW PROPER PROCEDURE FOR TREE FELLING (See Figure 12-15) 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. Trees should not be felled in a manner that would endanger any person, strike any utility line or cause any property damage.
OPERATING YOUR CHAIN SAW NOTE: Never cut through to the notch. Always leave a band of wood between the notch and back cut (approximately 2" (5 cm) 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.
OPERATING YOUR CHAIN SAW REMOVING BUTTRESS ROOTS (See Figure 16) A buttress root is a large root extending from the trunk of the tree above the ground. Remove 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 Figure 17) Bucking is the term used for cutting a fallen tree to the desired log length.
OPERATING YOUR CHAIN SAW BUCKING WITH A WEDGE (See Figure 18) 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 Figure 19) 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 bothe edn, cut 1/3 of the diameter from the top overback.
OPERATING YOUR CHAIN SAW LIMBING (See Figure 22) Limbing is removing branches from a fallen tree. ] < < < ^ < 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.
OPERATING YOUR CHAIN SAW 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.
BATTERY CHARGER CHARGING PROCEDURE (See Figure 11. ) NOTE: The battery is not shipped fully charged. It is recommended to fully charge before first use to ensure that maximum run time can be achieved. This lithium-ion battery will not develop a memory and may be charged at any time. A fully discharged battery pack will require approximately 90 minutes to fully charge from a discharged state. 1. Plug the charger into an AC power outlet. 2. Insert the battery pack (3) into the charger.
BATTERY CHARGER WA R N I N G If the battery is inserted into the charger when warm or hot, the CHARGING LED indicator light on the charger may switch on and illuminate ORANGE. If this occurs allow the battery to cool outside of the charger for approximately 30 minutes. CHARGER MAINTENANCE charger from the power source. To ensure safety and reliability all repairs should be performed 50 and 100 F CHARGER MOUNTING (See Figure 12. ) Fig.
MAINTENANCE WA R N I N G When servicing, use only identical 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 and may be damaged by their use.
MAINTENANCE C A U T I O N Always wear gloves when handling the bar and chain; these components are sharp and may contain burrs. WA R N I N G Never touch or adjust the chain while the motor is running. The saw chain is very sharp; always wear protective gloves when performing maintenance to the chain to avoid possible serious lacerations.

MAINTENANCE ADJUSTING THE CHAIN TENSIO (See Figure 35-36) WA R N I N G ~ + % < $ < + ^ < wear protective gloves when performing maintenance on the chain. Stop the motor and remove the battery from the chain saw before setting the chain tension. Slightly loosen the chain cover lock bolt. Turn the chain tensioning bolt clockwise to tension the chain.
MAINTENANCE CHAIN MAINTENANCE (See Figure 37) 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 Figure 38-41) = obtained only when all cutters are uniform. C A U T I O N Make sure the battery is removed from the chain saw before you work on the saw. WA R N I N G The saw chain is very sharp.

LESS THAN 30° – for cross cutting. MORE THAN 30° – feathered edge dulls quickly.
MAINTENANCE SIDE PLATE ANGLE (See Figure 43) $ HOOK – “Grabs” and dulls quickly; increases the potential of KICKBACK.
MAINTENANCE MAINTAINING THE GUIDE BAR (See Figure 47) Every week of use, reverse the guide bar on the saw to distribute the wear for maximum bar life. The bar should be cleaned every day of use and checked for wear and damage. Feathering or burring of the bar rails is a normal process of bar wear. Such faults should be smoothed with a file as soon as they occur.
