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 Husqvarna River, for production of muskets. The location was logical, since water power was harnessed from the Huskvarna River to create the waterpowered plant.

GENERAL SAFETY PRECAUTIONS General power tool safety warnings ! WARNING! Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury. moment of inattention while operating power tools may result in serious personal injury. • Use personal protective equipment. Always wear eye protection.
GENERAL SAFETY PRECAUTIONS • Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool´s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools. • 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.
GENERAL SAFETY PRECAUTIONS a result of tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below: • 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.
GENERAL SAFETY PRECAUTIONS Important provide information about which training materials and courses are available. IMPORTANT! This chain saw for forest service is designed for forest work such as felling, limbing and cutting. You should only use the saw with the bar and chain combinations we recommend in the chapter Technical data.
GENERAL SAFETY PRECAUTIONS • Automatic switch off functionality Fire Extinguisher and Shovel The machine is equipped with an automatic shutdown feature that deactivates the machine if not used. The machine will deactivate after 1 minute. Chain brake and front hand guard Generally clothes should be close-fitting without restricting your freedom of movement. IMPORTANT! Sparks can come from the bar and chain or other sources. Always have fire extinguishing tools available if you should need them.
GENERAL SAFETY PRECAUTIONS • Use the chain brake as a ”parking brake” when starting and when moving over short distances, to reduce the risk of moving chain accidentally hitting your leg or anyone or anything close by. • To release the chain brake pull the front hand guard backwards, towards the front handle. • Kickback can be very sudden and violent. Most kickbacks are minor and do not always activate the chain brake. If this happens you should hold the chain saw firmly and not let go.
GENERAL SAFETY PRECAUTIONS the saw chain. Third, the chain brake may be activated but if the bar is too close to you the brake might not have enough time to slow down and stop the chain before the chain saw hits you. Only you and proper working technique can eliminate kickback and its danger. Vibrations Cutting hardwoods (most broadleaf trees) creates more vibration than cutting softwoods (most conifers).
GENERAL SAFETY PRECAUTIONS ! ! WARNING! Avoid all skin contact with battery acid. Battery acid may cause skin irritation, burns or corrosive injuries. If you get acid in your eyes, do not rub but flush your eyes with plenty of water for at least 15 minutes. See a doctor. You must wash any exposed skin with copious amounts of water and soap in case of incidental contact. WARNING! Never connect the battery terminal to keys, coins, screws or other metal as this may short-circuit the battery.
GENERAL SAFETY PRECAUTIONS • Keep the chain’s cutting teeth properly sharpened! Follow our instructions and use the recommended file gauge. A damaged or badly sharpened chain increases the risk of accidents. Saw chain A chain is made up of a number of links, which are available in standard and low-kickback versions. IMPORTANT! No saw chain design eliminates the danger of kickback. • • • Maintain the correct depth gauge setting! Follow our instructions and use the recommended depth gauge clearance.
GENERAL SAFETY PRECAUTIONS • difference in height between the two (depth gauge setting). Chain oil hole and hole for chain tensioner. The bar must be matched to the chain saw design. Saw chain • • • Chain pitch (inches) When you sharpen a cutting tooth there are four important factors to remember. 1 Filing angle 2 Cutting angle 3 File position 4 Round file diameter Drive link width (mm/inches) Number of drive links.
GENERAL SAFETY PRECAUTIONS data for information on the size of file and gauge that are recommended for the chain fitted to your chain saw. Adjustment of depth gauge setting Li-ion • • • The cutting teeth should be newly sharpened before adjusting the depth gauge setting. We recommend that you adjust the depth gauge setting every third time you sharpen the cutting teeth. NOTE! This recommendation assumes that the length of the cutting teeth is not reduced excessively.
GENERAL SAFETY PRECAUTIONS Tension the chain as tightly as possible, but not so tight that you cannot pull it round freely by hand. • Turn the knob anti clockwise to loosen the drive sprocket cover. • Adjust the tension on the chain by turning the chain tensioner wheel down (+) for tighter tension and up () to loosen the tension. • Tighten the bar clutch by turning the knob clockwise. • Fold the knob back in to lock the tensioning.
GENERAL SAFETY PRECAUTIONS Never use waste oil! Using waste oil can be dangerous to you and damage the machine and environment. If the chain lubrication is not working: • Check that the oil channel in the bar is not obstructed. Clean if necessary. • Check that the groove in the edge of the bar is clean. Clean if necessary. • Check that the bar tip sprocket turns freely and that the lubricating hole in the tip sprocket is not blocked. Clean and lubricate if necessary.
GENERAL SAFETY PRECAUTIONS Checking wear on cutting equipment Li-ion Check the chain daily for: • Visible cracks in rivets and links. • Whether the chain is stiff. • Whether rivets and links are badly worn. Replace the saw chain if it exhibits any of the points above. We recommend you compare the existing chain with a new chain to decide how badly the existing chain is worn. When the length of the cutting teeth has worn down to only 4 mm the chain must be replaced.
ASSEMBLY Fitting the bar and chain should be tensioned until it does not sag from the underside of the bar. Li-ion ! ! WARNING! Always remove the battery before any assembly, maintenance and/ or checking is done on the machine. WARNING! Always wear gloves, when working with the chain. The chain is correctly tensioned when there is no slack on the underside of the bar, and it can still be turned easily by hand. Tighten the bar nut with the combination spanner while holding up the tip of the bar.
ASSEMBLY sprocket and in the groove on the bar. Begin on the top side of the bar. • Make sure that the edges of the cutting links are facing forward on the top edge of the bar. Mount the clutch cover and remember to fit the chain adjuster pin in the hole in the bar. Check that the drive links of the chain fit correctly over the drive sprocket and that the chain is correctly located in the groove in the bar. • Tension the chain by turning the wheel down (+).

WORKING TECHNIQUES Before use: General working instructions 5 IMPORTANT! 3 10 4 1 9 2 This section describes basic safety rules for using a chain saw. This information is never a substitute for professional skills and experience. If you get into a situation where you feel unsafe, stop and seek expert advice. Contact your chain saw dealer, service agent or an experienced chain saw user.
WORKING TECHNIQUES lose control. Both situations can cause serious personal injury. 6 Before moving your chain saw deactivate it and lock the saw chain using the chain brake. Carry the chain saw with the bar and chain pointing backwards. Fit a guard to the bar before transporting the chain saw or carrying it for any distance. 7 When you put the chain saw on the ground, lock the saw chain using the chain brake and ensure you have a constant view of the machine.
WORKING TECHNIQUES without any resistance from the chain during cutting, can lead to serious damage to the motor). the saw chain is jamming, the saw may be pushed back at you. • Cutting from above = Cutting on the pull stroke. • Cutting from below = Cutting on the push stroke. Cutting on the push stroke increases the risk of kickback. See instructions under the heading How to avoid kickback. Terms Limbing = Cutting branches off a felled tree.
WORKING TECHNIQUES ! WARNING! If the saw chain jams in the cut: deactivate the machine! Do not try to pull the machine free. If you do you may be injured by the saw chain when the machine suddenly brakes free. Use a lever to open up the cut and free the machine. The log is supported at one end. There is a high risk that it will split. Start by cutting from below (about 1/3 of the way through).
WORKING TECHNIQUES • Wind direction 2 Retreat path • Arrangement of branches 3 Felling direction • Weight of snow Felling • Obstacles within the reach of the tree: for example, other trees, power lines, roads and buildings. • Look for signs of damage and rot in the stem, this makes it more probably that the tree will break and start to fall before you expect it to.
WORKING TECHNIQUES Make the felling cut about 3-5 cm (1.5-2 inches) above the bottom directional cut. Set the spike bumper (if one is fitted) just behind the felling hinge. Use full throttle and advance the chain/bar slowly into the tree. Make sure the tree does not start to move in the opposite direction to your intended felling direction. Drive a wedge or breaking bar into the cut as soon as it is deep enough.
WORKING TECHNIQUES Cutting trees and branches that are in tension Preparations: Work out which side is in tension and where the point of maximum tension is (i.e. where it would break if it was bent even more). Decide which is the safest way to release the tension and whether you are able to do it safely. In complicated situations the only safe method is to put aside your chain saw and use a winch. General advice: Position yourself so that you will be clear of the tree or branch when the tension is released.
WORKING TECHNIQUES Limbing ! WARNING! A majority of kickback accidents occur during limbing. Do not use the kickback zone of the guide bar. Be extremely cautious and avoid contacting the log, other limbs or objects with the nose of the guide bar. Be extremely cautious of limbs under tension. They can spring back toward you and cause loss of control resulting in injury. Make sure that you can stand and move about safely. Work on the left side of the trunk.
MAINTENANCE General Checking the inertia brake release The user must only carry out the maintenance and service work described in this Operator's Manual. More extensive work must be carried out by an authorized service workshop. • Checking, maintaining and servicing chain saw safety equipment Place the chain saw, deactivated, above a stump or other stable surface. Release the front handle and let the chain saw fall by its own weight, rotating around the rear handle towards the stump.
MAINTENANCE Power trigger lockout Keypad • • Make sure that the power trigger is locked at the idle setting when the power trigger lockout is released. • Press the power trigger lockout and make sure it returns to its original position when released. Activate the chain saw (green LED on) and make sure the chain saw deactivates when the start/stop button is pressed (green LED off).
