SAFETY INSTRUCTIONS PERSONAL PROTECTIVE EQUIPMENT MOST CHAIN SAW ACCIDENTS HAPPEN WHEN THE CHAIN TOUCHES THE OPERATOR. You must use approved personal protective equipment whenever you use the machine. Personal protective equipment cannot eliminate the risk of injury but it will reduce the degree of injury if an accident does happen. Ask your dealer for help in choosing the right equipment. Long or continuous exposure to high noise levels may cause permanent hearing impairment.
SAFETY INSTRUCTIONS 1 Chain brake and front hand guard 3a Starting YOUR chain saw is equipped with a chain brake that is designed to stop the chain immediately if you get a kickback. The chain brake reduces the risk of accidents, but only You can prevent them. The chain brake must be engaged when the chain saw is started. b You can also use the chain brake as a temporary brake when you change position or if you put the saw down for a short time.
SAFETY INSTRUCTIONS 6 The way the chain brake is triggered, either manually or automatically, depends on the force of the kickback and the position of the chain saw in relation to the object that the kickback zone of the bar strikes. If you get a violent kickback while the kickback zone of the bar is farthest away from you the chain brake will be activated by the movement of the counterweight (INERTIA ACTIVATED).
SAFETY INSTRUCTIONS 5 Vibration damping system 6 Stop switch Your chain saw is equipped with a vibration damping system that is designed to minimise vibrations and make operation easier. Use the stop switch to switch off the engine. When you use a chain saw vibrations are generated by the uneven contact between the chain and the wood you are cutting. Cutting hardwoods (most broadleaf trees) creates more vibration than cutting softwoods (most conifers).
SAFETY INSTRUCTIONS Inspecting, maintaining and servicing chain saw safety equipment 3 SPECIAL TRAINING IS REQUIRED to service and repair chain saws. This is especially true of chain saw safety equipment. If your chain saw fails any of the checks described below take it to your SERVICE AGENT. When you buy any of our products we guarantee the availability of professional repairs and service. If the retailer who sells your saw is not a SERVICING DEALER, ask him for the address of your nearest SERVICE AGENT.
SAFETY INSTRUCTIONS 2 Throttle lock 1 Make sure the throttle control is locked at the idle setting when you release the throttle lock. 2 Press the throttle lock and make sure it returns to its original position when you release it. 4 Right hand guard Check that the right hand guard is not damaged and that there are no visible defects, such as cracks.
SAFETY INSTRUCTIONS 7 Muffler Never use a chain saw that has a faulty muffler. CUTTING EQUIPMENT This section describes how to choose and maintain your cutting equipment in order to: • Reduce the risk of kickback. • Reduce the risk of the chain breaking or jumping. • Obtain maximum cutting performance. • Extend the life of cutting equipment. The 5 basic rules 1 Only use cutting equipment recommended by us! See the ”Technical data” section.
SAFETY INSTRUCTIONS 1 Cutting equipment designed to minimise kickback Faulty cutting equipment or the wrong combination of bar and chain increases the risk of kickback. Use only the bar and chain combinations recommended in the ”Technical data” section. The only way to avoid kickback is to make sure that the kickback zone of the bar never touches anything. By using cutting equipment with “built-in” kickback protection and keeping the chain sharp and well-maintained you can reduce the effects of kickback.
SAFETY INSTRUCTIONS 2 Sharpening your chain and adjusting raker clearance The risk of kickback is increased with a badly sharpened chain! It is very difficult to sharpen a chain correctly without the right equipment. We recommend you use a file gauge. This will help you obtain the maximum kickback reduction and cutting performance from your chain. A General information on sharpening cutting teeth • Never use a blunt chain.
SAFETY INSTRUCTIONS C General advice on setting raker clearance • When you sharpen the cutting teeth you reduce the RAKER CLEARANCE (cutting depth). To maintain cutting performance you must file back the raker teeth to the recommended height. See the ”Technical data” section to find the raker clearance for your saw chain. • On a low-kickback cutting link the front edge of the raker lip is rounded. It is very important that you maintain this radius or bevel when you adjust the raker clearance.
SAFETY INSTRUCTIONS 4 Lubricating cutting equipment 1 2 3 Undo the bar nuts that hold the clutch cover and chain brake, using the combination spanner. Then tighten the nuts by hand as tight as you can. Raise the tip of the bar and stretch the chain by tightening the chain tensioning screw using the combination spanner. Tighten the chain until it not hang slack on the underside of the bar. Use the combination spanner to tighten the bar nuts while lifting the tip of the bar at the same time.
SAFETY INSTRUCTIONS C Checking chain lubrication E Needle bearing maintenance • Check the chain lubrication each time you refuel. Aim the tip of the saw at a light coloured surface about 20 cm away. After 1 minute running at 3/4 throttle you should see a distinct line of oil on the light surface.
SAFETY INSTRUCTIONS H Bar HOW TO AVOID KICKBACK Check regularly: • Whether there are burrs on the edges of the bar. Remove these with a file if necessary. Kickback can happen very suddenly and violently; kicking the 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.
SAFETY INSTRUCTIONS General rules 1 If you understand what kickback is and how it happens then you can reduce or eliminate the element of surprise. By being prepared you reduce the risk. Kickback is usually quite mild, but it can sometimes be very sudden and violent. 2 Always hold the saw firmly with your right hand on the rear handle and your left hand on the front handle.
SAFETY INSTRUCTIONS GENERAL SAFETY PRECAUTIONS 1 Chain saws are designed solely for cutting wood. The only cutting equipment that can be used with this chain saw are the combinations of bars and chains recommended in the ”Technical data” section. 2 Never use a chain saw if you are tired, if you have drunk alcohol, or if you are taking medication that affects your vision, your judgement or your coordination.
SAFETY INSTRUCTIONS • Never try to refuel the saw while it is running. 1 Basic safety rules • Make sure there is plenty of ventilation when refuelling or mixing fuel (2-stroke mixture). • to make sure there are no people, animals or other objects nearby that might affect your work. • Move the saw at least 3 m from the refuelling point before starting it. • to make sure that none of the above might come within reach of your saw or be injured by falling trees.
SAFETY INSTRUCTIONS 6 Before moving your chain saw switch off the engine and lock the chain using the chain brake. Carry the saw with the bar and chain pointing backwards. Fit a guard to the bar before carrying the saw any distance. Never carry or hang the saw by the trigger. This could damage the mechanism and disable the chain brake. 3 Make sure the chain will not strike the ground or any other object during or after cutting.
SAFETY INSTRUCTIONS 2 The log is supported at one end. There is a high risk that it will split. 3 Tree felling technique It takes a lot of experience to fell a tree. Inexperienced users of chain saws should not fell trees. NEVER ATTEMPT A TASK YOU ARE UNSURE OF. A Safe distance A Start by cutting from below (about 1/3 of the way through). The safe distance between a tree that is to be felled and anyone else working nearby is at least 21/2 tree lengths.
SAFETY INSTRUCTIONS C Clearing the trunk and preparing your retreat Remove any branches that are in the way. To do this it is best to work from the top down and keep the trunk between you and the chain saw. Never limb above shoulder height. Remove any undergrowth from the base of the tree and check the area for obstacles (stones, branches, holes, etc.) so that you have a clear path of retreat when the tree starts to fall.
SAFETY INSTRUCTIONS We recommend that you use a bar that is longer than the diameter of the tree, so that you can make the FELLING CUT and DIRECTIONAL CUT with single cutting stokes. (See ”Technical data” to find out which lengths of bar are recommended for your saw). 4 Freeing a tree that has fallen badly = high accident risk A Freeing a “Trapped tree” The safest method is to use a winch. A Tractor-mounted B Portable There are methods for felling trees with a diameter larger than the bar length.

ASSEMBLY Mounting guide bar and chain Always wear gloves, when working with the chain, in order to protect your hands from injury. Check that the chain brake is in disengaged position by moving the front hand guard towards the front handle. Hold up the tip of the bar and tighten the chain. The chain is correctly tensioned when there is no slack on the underside of the bar, but it can still be turned easily by hand. Hold up the bar tip and tighten the bar nuts with the combination wrench.
FUEL HANDLING Fuelmix Mixing IMPORTANT! The chain saw is equipped with a two-stroke engine and must always been run using a mixture of petrol and two-stroke engine oil. It is important to accurately measure the amount of oil to be mixed to ensure that the correct mixture is obtained. When mixing small amounts of fuel, even small inaccuracies can drastically affect the ratio of the mixture. Always provide for good ventilation when handling fuel.
FUEL HANDLING Chain oil • The chain lubrication system is automatic. Always use special chain oil with good adhesive characteristics. • In countries where no special chain oil is available, EP 90 transmission oil can be used. • Never use waste oil. This results in damage to the oil pump, the bar and the chain. • It is important to use oil of the right viscosity according to the air temperature. • In temperatures below 0oC (32oF) some oils become too viscous.
START AND STOP Start and stop Start WARNING! • Never start a chain saw unless the bar, chain and all covers are fitted correctly. Otherwise the clutch can come loose and cause personal injuries. • Always move the saw away from the fueling area before starting. • Place the saw on clear ground and make sure that the chain is not contacting anything. Also, make sure that you have a secure footing. • Keep people and animals well away from the working area.
MAINTENANCE Carburettor Conditions Functioning, Basic setting, Final setting • Before any adjustments are made the air filter should be clean and the cylinder cowling fitted. Adjusting the carburettor while a dirty air filter is in use will result in a leaner mixture when the filter is finally cleaned. This can give rise to serious engine damage. • Carefully turn the L and H-jets clockwise to the bottom. Now turn the jets one turn anti-clockwise. The carburettor is now set to H = 1 and L = 1.
MAINTENANCE Starter device WARNING! • When the recoil spring is assembled in the starter housing, it is in tensioned position and can when treated carelessly, pop out and cause injuries. • Always be careful, when changing the recoil spring or the starter cord. Always wear safety goggles for eye protection. Tensioning the recoil spring • Lift the starter cord up in the notch on the starter pulley and turn the starter pulley 2 turns clockwise.
MAINTENANCE Muffler Air filter The air filter must be regularly cleaned from dust and dirt in order to avoid: • Carburettor malfunctions • Starting problems • Engine power reduction • Unnecessary wear on the engine parts • Abnormal fuel consumption Clean the air filter daily or more often if the air is exceptionally dusty in the working area. • Disassemble the air filter by removing the cylinder cover and unscrew the filter. When reassembling, make sure that the filter is tight against the filter holder.
MAINTENANCE Adjustment of the oil pump (346XP/353) The oil pump is adjustable. Adjustments are made by turning the screw using a screwdriver or combination spanner. The saw is supplied from the factory with the screw set to position 2. Turning the screw clockwise will reduce the oil flow and turning the screw anti-clockwise will increase the oil flow.
MAINTENANCE Below you will find some general maintenance instructions. If you have more questions, contact your servicing dealer. Weekly maintenance 1. Daily maintenance 1. 2. Check the throttle trigger for smooth operation. If any binding occurs, or if engine fails to return to idle, the saw should be taken to your dealer, before it is used again. Also, be sure that the trigger cannot be pulled until the throttle trigger lockout is depressed. Clean or replace the air filter as necessary.
