3. Press the throttle trigger lockout and make sure that it returns to its intial position when you release it. easier. The vibration damping system of the product decreases the transfer of vibration between the engine unit and the shaft unit of the product. 1. Stop the engine. 2. Do a visual check for deformation and damage for example, cracks. 4. Do a check of the throttle control and throttle trigger lockout move freely and that the return springs work properly. 3.
• Do a visual check on the spark arrestor mesh. • • • • Only use approved containers when you move the fuel or put the fuel into storage. Empty the fuel tank before long-term storage. Obey the local law on where to dispose fuel. Clean the product before long-term storage. Remove the spark plug cap before you put the product into storage to make sure that the engine does not start accidentally. Safety instructions for maintenance Refer to To do maintenance on the muffler on page 16.
• Keep the correct depth gauge setting. Obey the instructions and use the recommended depth gauge setting. • Make sure that the saw chain has the correct tension. If the saw chain is not tight against the guide bar, the saw chain can derail. An incorrect saw chain tension increases wear on the guide bar, saw chain and chain drive sprocket. Refer to To tension the chain on page 20. • Do maintenance on the cutting equipment regularly and keep it correctly lubricated.
3. Make sure that the edges of the cutting links are facing forward on the top edge of the guide bar. 7. When fitting a new chain, the chain tension has to be checked frequently until the chain is run-in. Check the chain tension regularly. A correctly tensioned chain ensures good cutting performance and long life. To adjust the length of the shaft 1. Undo the knob. 4. Fit the cover and locate the chain adjuster pin (A) in the hole in the bar.
Operation Introduction WARNING: Before you operate the product, you must read and understand the safety chapter. To check before starting • Always use new unleaded gasoline with a minimum octane number of 90 RON (87 AKI) and with less than 10% ethanol concentration (E10). Use gasoline with a higher octane number if you frequently use the product at continuously high engine speed. • Two-stroke oil 1. Inspect the working area. Remove any objects that could be thrown out. • 2. Check the saw chain.
3. Shake the fuel mixture. 4. Add the remaining quantity of gasoline to the container. 5. Carefully shake the fuel mixture. CAUTION: Do not mix fuel for more than 1 month at a time. To fill the fuel tank 1. Clean the area around the fuel tank cap. Note: This product has an automatic chain lubrication system. You can also adjust the oil flow. Refer to To adjust chain lubrication on page 21. • • • 2. Shake the container and make sure that the fuel is fully mixed.
• • Cut large branches in sections so that you have better control over where they fall. To prepare the product for start 1. Press the air purge repeatedly until the fuel starts to fill the bulb. Never cut through the swelling at the root of the branch as this will slow down healing and increase the risk of fungal attack! Note: It is not necessary to fully fill the bulb. 2. Move the choke control up into choke position. • Use the stop at the base of the cutting head to provide support during cutting.
CAUTION: Do not pull the starter rope all the way out and do not let go off the starter rope handle when the starter rope is fully extended. This can cause damage to the product. To stop the product 1. Move the stop switch into the stop position to stop the engine. 6. Pull the starter rope again and again until the engine starts. 7. Reset the choke when the engine fires. 8. Operate the throttle gradually when the engine starts. 9. Make sure the engine runs smoothly.
Maintenance Daily Clean the air filter. Replace if necessary. X Check the saw chain with regard to visible cracks in the rivets and links, whether the saw chain is stiff or whether the rivets and links are abnormally worn. X Clean the area under the protective cover. X Make sure that the screws and nuts are tight. X Examine the engine, the fuel tank and the fuel lines for leaks. X Weekly Clean the cooling system. X Examine the starter and the starter rope for damages.
To do maintenance on the muffler Cooling system The muffler decreases the noise level and directs the exhaust gases away from the operator. The product has a cooling system to keep the operation temperature as low as possible. WARNING: Mufflers that have catalytic converters get very hot during operation and will stay hot for some time after you stop the product. This also applies at idle speed. If you touch the product it can result in burns to the skin. Think about of the risk of fire. 1.
• If the spark plug is dirty, clean it and make sure that the electrode gap is correct, refer to Technical data on page 23. • Replace the spark plug if it is necessary. Air filter Remove dust and dirt from the air filter to keep it clean in order to prevent: • • • • • Carburettor malfunctions. Starting problems. Loss of engine power. Unnecessary wear to engine parts. Too much fuel consumption. Clean the air filter at an interval of 25 hours, or more regularly if conditions are unusually dusty.
4. Replace the saw chain when the longest part of the cutting tooth is less than 4 mm/0.16 in. Also replace the saw chain if there are cracks on the cutters. To do a check of the guide bar 6. Make sure that the bar tip sprocket turns freely and that the lubricating hole in the bar tip sprocket is not blocked. Clean and lubricate if it is necessary. 7. Turn the guide bar daily to extend its life cycle. 1. Make sure that the oil channel is not blocked. Clean if it is necessary.
• Chain pitch, in. The distance between the drive links of the saw chain must align with the distance of the teeth on the bar tip sprocket and drive sprocket. PITCH = D 2 D • Number of drive links. The number of drive links is decided by the type of guide bar. General information about how to sharpen the cutters Do not use a blunt saw chain. If the saw chain is blunt, you must apply more pressure to push the guide bar through the wood.
It is not easy to sharpen a saw chain correctly without the correct equipment. Use Husqvarna file gauge. This will help you to keep maximum cutting performance. Note: Refer to To sharpen the cutters on page 20 for information about sharpening of the saw chain. instructions about how to receive the correct depth gauge setting for your saw chain. A C B To sharpen the cutters 1. Use a round file and a file gauge to sharpen the cutting teeth.
1. Loosen the bar nut that hold the clutch cover/chain brake. Use a wrench. 2. Tighten the bar nuts by hand as tightly as you can. 3. Lift the front of the guide bar and turn the chain tensioning screw. Use a wrench. To fill with chain oil 1. Open the oil cap on top of the bar head. 2. Fill with Husqvarna saw chain oil. 3. Attach the cap again. To check the chain lubrication 1. Check the chain lubrication each time you refuel.
• Turn the adjuster screw anticlockwise to decrease the oil flow. Troubleshooting The engine does not start Check Possible cause Procedure Stop switch. The stop switch is in the stop position. Let an approved service agent replace the stop switch. Fuel tank. Incorrect fuel type. Drain the fuel tank and fill with correct fuel. Spark plug and cylinder. The spark plug is dirty or wet. Make sure that the spark plug is dry and clean. The spark plug electrode gap is incorrect. Clean the spark plug.
• Attach the product safely during transportation. To prepare your product for long-term storage 2. Attach the transportation guard. 3. Clean the product. Refer to Maintenance on page 14 for instructions. 4. Do a complete servicing of the product. 1. Disassemble and clean the saw chain and the groove in the guide bar. CAUTION: If the saw chain and guide bar are not cleaned, they can become rigid or blocked. Technical data Technical data 525PT5S Engine Cylinder displacement, cm3 25.
