INTRODUCTION Dear customer! Congratulations on your choice to buy a Husqvarna product! Husqvarna is based on a tradition that dates back to 1689, when the Swedish King Karl XI ordered the construction of a factory on the banks of the Huskvarna River, for production of muskets. The location was logical, since water power was harnessed from the Huskvarna River to create the water-powered plant.
GENERAL SAFETY PRECAUTIONS General power tool safety warnings ! the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury. • Use personal protective equipment. Always wear eye protection. Protetctive equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries. • Prevent unintentional starting.
GENERAL SAFETY PRECAUTIONS • Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control. • Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in hazardous situations.
GENERAL SAFETY PRECAUTIONS • Maintain a firm grip, with thumbs and fingers encircling the chain saw handles, with both hands on the saw and position your body and arm to allow you to resist kickback forces. Kickback forces can be controlled by the operator, if proper precautions are taken. Do not let go of the chain saw. • Do not overreach and do not cut above shoulder height. This helps prevent unintended tip contact and enables better control of the chain saw in unexpected situations.
GENERAL SAFETY PRECAUTIONS Important IMPORTANT! This chain saw for forest service is designed for forest work such as felling, limbing and cutting. The product is designed to manage 10-15 cm (4-6 inch) wood. Work is constantly in progress to improve the design and technology - improvements that increase your safety and efficiency. Visit your dealer regularly to see whether you can benefit from new features that have been introduced.

The warning indicator (3) flashes if the chain brake is activated or if there is a risk of overload. The overload protection temporarily deactivates the machine. When the machine is restored to normal temperature it is again ready for use. Solid light indicates need for service.
GENERAL SAFETY PRECAUTIONS Chain catcher ! The chain catcher is designed to catch the chain if it snaps or jumps off. This should not happen if the chain is properly tensioned (see instructions under the heading Assembly) and if the bar and chain are properly serviced and maintained (see instructions under the heading General working instructions).
GENERAL SAFETY PRECAUTIONS • Keep all cords and extension cords away from water, oil and sharp edges. Make sure the cord is not pinched in doors, fences or the like. Otherwise it can cause the object to become live. ! more likely to break and lead to increased wear on the bar, chain and drive sprocket. Cutting equipment designed to reduce kickback WARNING! Do not use the battery charger close to corrosive or flammable materials. Do not cover the battery charger.
GENERAL SAFETY PRECAUTIONS Saw chain • Chain pitch (inches) (Figure 14) • Drive link width (mm/inches) (Figure 17) • Number of drive links. (Figure 16) Sharpening your chain and adjusting depth gauge setting ! one side first, then turn the chain saw and file the teeth on the other side. (Figure 20) • General advice on adjusting depth gauge setting • Always wear gloves, when working with the chain. General information on sharpening cutting teeth • Never use a blunt chain.
GENERAL SAFETY PRECAUTIONS • Release the knob by folding it out until it snaps open. (Figure 28) • Turn the knob anti clockwise to loosen the drive sprocket cover. (Figure 29) • Adjust the tension on the chain by turning the chain tensioner wheel down (+) for tighter tension and up () to loosen the tension. (Figure 30) If the chain lubrication is not working: • Check that the oil channel in the bar is not obstructed. Clean if necessary.
GENERAL SAFETY PRECAUTIONS ! WARNING! Most chain saw accidents happen when the chain touches the operator. Wear personal protective equipment. See instructions under the heading ”Personal protective equipment”. Do not tackle any job that you feel you are not adequately trained for. See instructions under the headings Personal protective equipment, How to avoid kickback, Cutting equipment and General working instructions. Avoid situations where there is a risk of kickback.
ASSEMBLY Fitting the bar and chain ! WARNING! Always remove the battery before any assembly, maintenance and/ or checking is done on the machine. Always wear gloves, when working with the chain. • Check that the chain brake is in disengaged position by moving the front hand guard towards the front handle. (Figure 42) • Remove the drive sprocket cover by turning the knob counterclockwise. Take off the transportation guard (A). (Figure 43) • Fit the bar over the bar bolt.
BATTERY HANDLING Battery The display shows the battery capacity and if there are any problems with the battery. The battery capacity is displayed for 5 seconds after the machine is switched off or the battery indicator button (1) is pressed. The warning symbol on the battery is lit when an error has occurred (2). See fault codes. (Figure 49) LED lights Battery status All LEDs are lit Fully charged (67%– 100%). LED 1, LED 2 are lit. The battery is 34%-66% charged. LED 1 is lit.
STARTING AND STOPPING Starting and stopping ! WARNING! Note the following before starting: Never start a chain saw unless the bar, chain and all covers are fitted correctly. Otherwise the drive sprocket can come loose and cause personal injuries. Make sure you have a secure footing and that the chain cannot touch anything. Keep people and animals well away from the working area.
WORKING TECHNIQUES Before use: (Figure 62) 1 Check that the chain brake works correctly and is not damaged. 2 Check that the rear right hand guard is not damaged. 3 Check that the power trigger lockout works correctly and is not damaged. 4 Check that the keypad works correctly and is not damaged. 5 Check that all handles are free from oil. 6 Check that all parts of the chain saw are tightened correctly and that they are not damaged or missing.
WORKING TECHNIQUES Lack of concentration can lead to kickback if the kickback zone of the bar accidentally touches a branch, nearby tree or some other object. Have control over the workpiece. If the pieces you intend to cut are small and light, they can jam in the saw chain and be thrown towards you. Even if this does not need to be a danger, you may be surprised and lose control of the saw. Never saw stacked logs or branches without first separating them. Only saw one log or one piece at a time.
WORKING TECHNIQUES Cutting/bucking ! WARNING! Never attempt to cut logs while they are in a pile or when a couple of logs are lying together. Such procedures drastically increase the risk of kickback which can result in a serious or fatal injury. If you have a pile of logs, each log you attempt to cut should be removed from the pile, placed on a saw horse or runners and cut individually. Remove the cut pieces from the cutting area.
WORKING TECHNIQUES Freeing a tree that has fallen badly Felling ! WARNING! Unless you have special training we advise you not to fell trees with a diameter larger than the bar length of your saw! Felling is done using three cuts. First you make the directional cuts, which consist of the top cut and the bottom cut, then you finish with the felling cut. By placing these cuts correctly you can control the felling direction very accurately.
WORKING TECHNIQUES Kickback always occurs in the cutting plane of the bar. Normally the chain saw and bar are thrown backwards and upwards towards the user. However, the chain saw may move in a different direction depending on the way it was being used when the kickback zone of the bar touched the object. Kickback only occurs if the kickback zone of the bar touches an object. (Figure 4) Limbing ! WARNING! A majority of kickback accidents occur during limbing. Do not use the kickback zone of the guide bar.
MAINTENANCE General Power trigger lockout The user must only carry out the maintenance and service work described in this manual. More extensive work must be carried out by an authorized service workshop. • Make sure that the power trigger is locked at the idle setting when the power trigger lockout is released. (Figure 102) • Press the power trigger lockout and make sure it returns to its original position when released.
