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 8 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 9: 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 10: Cutting Equipment
GENERAL SAFETY PRECAUTIONS with cutting equipment that is blunt or faulty (wrong type or badly sharpened) will increase the vibration level. WARNING! Overexposure to vibration can lead to circulatory damage or nerve damage in people who have impaired circulation. Contact your doctor if you experience symptoms of overexposure to vibration. -
Page 11: Sharpening Your Chain And Adjusting Depth Gauge Setting
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 12 GENERAL SAFETY PRECAUTIONS • The cutting part of the chain is called the cutter and consists of a cutting tooth (A) and the depth gauge (B). The cutters cutting depth is determined by the difference in height between the two (depth gauge setting).
-
Page 13: Lubricating Cutting Equipment
GENERAL SAFETY PRECAUTIONS Adjustment of depth gauge setting • 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. - Page 14 GENERAL SAFETY PRECAUTIONS Filling with chain oil • All our chain saws have an automatic chain lubrication system. On some models the oil flow is also adjustable. • The saw chain oil tank and the fuel tank are designed so that the fuel runs out before the saw chain oil. However, this safety feature requires that you use the right sort of chain oil (if the oil is too thin it will run out before the fuel), and that you adjust the carburetor as...
- Page 15 GENERAL SAFETY PRECAUTIONS Checking wear on cutting equipment 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.

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 17: 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 18: Fueling
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. Always stop the engine and let it cool for a few minutes before refuelling. When refuelling, open the fuel cap slowly so that any excess pressure is released gently. -
Page 19: 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 20 • Never start a chain saw unless the bar, chain and all covers are fitted correctly. See instructions under the heading Assembly. Without a bar and chain attached to the chain saw the clutch can come loose and cause serious injury. •...

Take great care when cutting a tree that is under tension. A tree that is under tension may spring back to its normal position before or after being cut. If you position yourself incorrectly or make the cut in the wrong place the tree may hit you or the machine and cause you to lose control. - Page 23 The chainsaw should be fitted with a suitable strop for attaching to the operator’s harness: a) choke the strop around the attachment point on the rear of the saw.

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 25: Felling Technique For Tree Tops
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 26 Felling direction The aim is to fell the tree in a position where you can limb and cross-cut the log as easily as possible. You want it to fall in a location where you can stand and move about safely. The main thing to avoid is that the falling tree top should get jammed in another tree.

Page 28: 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. -

A damaged air filter must always be replaced. A HUSQVARNA chain saw can be equipped with different types of air filters according to working conditions, weather, season, etc. Contact your dealer for advice. -
Page 34: Spark Plug
Spark plug The spark plug condition is influenced by: • Incorrect carburetor adjustment. • An incorrect fuel mixture (too much or incorrect type of oil). • A dirty air filter. These factors cause deposits on the spark plug electrodes, which may result in operating problems and starting difficulties. -
