GENERAL SAFETY PRECAUTIONS Before using a new chain saw • Please read this manual carefully. • Check that the cutting equipment is correctly fitted and adjusted. See instructions under the heading Assembly. • Refuel and start the chain saw. See the instructions under the headings Fuel Handling and Starting and Stopping. -

Always have fire extinguishing tools available if you should need them. Help prevent forest fires. This top handle chainsaw is designed specifically for tree surgery and maintenance in the tree. Due to the special compact handle design (closely spaced handles), there is an increased risk of losing control. - Page 9 GENERAL SAFETY PRECAUTIONS Chain brake and front hand guard Your chain saw is equipped with a chain brake that is designed to stop the chain if you get a kickback. The chain brake reduces the risk of accidents, but only you can prevent them.
-
Page 10: Chain Catcher
GENERAL SAFETY PRECAUTIONS If the kickback is less violent or the kickback zone of the bar is closer to you the chain brake is designed to be activated manually by the movement of your left hand. • In the felling position the left hand is in a position that makes manual activation of the chain brake impossible. -
Page 11: Cutting Equipment
GENERAL SAFETY PRECAUTIONS equipment and the machine′s handle unit. The body of the chain saw, including the cutting equipment, is insulated from the handles by vibration damping units. Cutting hardwoods (most broadleaf trees) creates more vibration than cutting softwoods (most conifers). Cutting with cutting equipment that is blunt or faulty (wrong type or badly sharpened) will increase the vibration level. - Page 12 To maintain the safety features of the cutting equipment, you should replace a worn or damaged bar or chain with a bar and chain combinations recommended by Husqvarna. See instructions under the heading Technical Data for a list of replacement bar and chain combinations we recommend.

Page 13: Sharpening Your Chain And Adjusting Depth Gauge Setting
GENERAL SAFETY PRECAUTIONS Sharpening your chain and adjusting depth gauge setting General information on sharpening cutting teeth • Never use a blunt chain. When the chain is blunt you have to exert more pressure to force the bar through the wood and the chips will be very small. If the chain is very blunt it will produce wood powder and no chips or shavings. -
Page 14: Tensioning The Chain
GENERAL SAFETY PRECAUTIONS General advice on adjusting depth gauge setting • When you sharpen the cutting tooth (A) the depth gauge setting (C) will decrease. To maintain optimal cutting performance the depth gauge (B) has to be filed down to achieve the recommended depth gauge setting. -
Page 15: Lubricating Cutting Equipment
GENERAL SAFETY PRECAUTIONS Lubricating cutting equipment WARNING! Poor lubrication of cutting equipment may cause the chain to snap, which could lead to serious, even fatal injuries. Chain oil Chain oil must demonstrate good adhesion to the chain and also maintain its flow characteristics regardless of whether it is warm summer or cold winter weather. - Page 16 GENERAL SAFETY PRECAUTIONS Chain drive sprocket The clutch drum is fitted with one of the following drive sprockets: A Spur sprocket (the chain sprocket is welded on the drum) B Rim sprocket (replaceable) Regularly check the degree of wear on the drive sprocket. Replace if wear is excessive.

Fitting the bar and chain WARNING! 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. Unscrew the bar nut and remove the clutch cover (chain brake). -
Page 18: Fuel Handling
When working with continuous high revs (e.g. limbing) a higher octane is recommended. Environment fuel HUSQVARNA recommends the use of alkylate fuel or environmental fuel for four-stroke engines blended with two-stroke oil as set out below. Note that carburetor adjustment may be necessary when changing the type of fuel (see instructions under the heading Carburetor). -
Page 19: Fueling
• In temperatures below 32°F (0°C) some oils become too viscous. This can overload the oil pump and result in damage to the oil pump components. • Contact your service agent when choosing chain oil. Fueling WARNING! Taking the following precautions, will lessen the risk of fire: Do not smoke and do not place any hot objects in the vicinity of fuel. -
Page 20: Starting And Stopping
Starting and stopping WARNING! Note the following before starting: The chain brake must be engaged when the chain saw is started to reduce the chance of contact with the moving chain during starting. Never start a chain saw unless the bar, chain and all covers are fitted correctly. - Page 21 Note! Pull the front hand guard towards the front handle. The chain brake is now disengaged. Your saw is ready for use. WARNING! Long term inhalation of the engine’s exhaust fumes, chain oil mist and dust from sawdust can represent a health risk.

30 cm away from the trapped saw. Whether a handsaw or a chainsaw is used to free a stuck saw, the release cuts should always be outboard (toward the tips of the branch), in order to prevent the saw being taken with the section and further complicating the situation. - Page 26 In most cases you can avoid these problems by cutting in two stages; from the top and from the bottom. You need to support the object so that it will not trap the chain or split during cutting. WARNING! If the chain jams in the cut: stop the engine! Don’t try to pull the chain saw free.

Page 27: Felling Technique For Tree Tops
Felling technique for tree tops WARNING! It takes a lot of experience to fell a tree. Inexperienced users of chain saws should not fell trees. Do not attempt any task beyond your experience level! Safe distance During tree maintenance work above ground level, the working area must always be secured and marked out with signs, tape or the like. -
Page 28: Freeing A Tree That Has Fallen Badly
Felling cut The felling cut is made from the opposite side of the tree and it must be perfectly horizontal. Try to take a correct position so you are able to cut on the pull stroke. Make the felling cut about 1.5-2 inches (3-5 cm) above the bottom directional cut. -
Page 29: How To Avoid Kickback
How to avoid kickback WARNING! Kickback can happen very suddenly and violently; kicking the chain saw, bar and chain back at the user. If this happens when the chain is moving it can cause very serious, even fatal injuries. It is vital you understand what causes kickback and that you can avoid it by taking care and using the right working technique. -
