SAFETY INSTRUCTIONS Adjusting the harness and clearing saw ! WARNING! When working with the clearing saw it should always be hooked in the harness. If this is not done, you cannot control the clearing saw safely and this can result in injury to yourself or someone else. Never use a harness with a defective quick release catch. Basic clearing techniques • Always drop to idling speed after each working operation.
SAFETY INSTRUCTIONS Clearing‘s ABC A. B. C. D. E. F. G. H. Always use the correct equipment. Always have well adjusted equipment. Follow the safety instructions. Organise the work well. Always use full throttle when applying the blade. Always use a sharp blade. Avoid stones. Guide the direction of fall (use the wind). ! WARNING! Avoid cutting in the cutting region between 12 and 3 o‘clock on the blade.
SAFETY INSTRUCTIONS • Large stems must be cut from two sides. Determine in which direction the stem should fall. First apply the saw to the felling side. Then cut from the other side to fell the stem. The feed pressure should be applied with regard to the size of the stem‘s hardness. Small stems require more pressure, while large stems require less pressure. • If the stems are tightly packed adapt the through-speed with this in mind. • If the blade should jam in the stem, never jerk the machine free.
SAFETY INSTRUCTIONS Grass clearing using the trimmer head and plastic knifes • Hold the trimmer head just above the ground at an angle. It is the end of the cord that carries out the work. Let the cord work at its own pace. Do not press the cord into the area to be cut. • The cord can easily remove grass and weeds up against walls, fences, trees and borders, however, it can also damage sensitive bark on trees and bushes and damage fence posts.

ASSEMBLY Assembling the handlebars (240R, 245R, 250R) Assembling the handlebars (245RX, 252RX) • Remove the screw at the rear of the throttle handle. • Unscrew the handle from the handlebar bracket. • Slide on the throttle handle on the right-hand side of the handlebars, (see the diagram). • Position the handlebars as shown. Fit the bracket components and tighten the handle lightly. • Align the hole in the throttle handle for the fixing screw with the hole on the handlebars.
ASSEMBLY Assembling the handlebars (265RX) • Fit the left handle in the handle support. • Fit the right handle. • Make a first adjustment and tighten the screws slightly. • Then make the final adjustment with the clearingsaw in the harness, to obtain the most suitable working position. Tighten the screws. • Make a final adjustment of the right handle and fix it in the most comfortable position. Adjusting the throttle control Adjust the throttle control for the most suitable working position.
ASSEMBLY Assembly of the blade and trimmer head Assembling the blade guard and clearing blade It is extremely important that the disc drive’s/support flange’s guide engages correctly in the cutting equipment’s centre hole when assembling the cutting equipment. Cutting equipment assembled incorrectly can result in serious and/or fatal personal injury. • The guard (A) is fitted using 4 screws (L) as set out in the diagram. NOTE! Use the recommended blade guard.
ASSEMBLY Assembling the spray guard and trimmer head Trimmy SII • Fit the correct guard (A) for working with a trimmer head. Secure using 4 bolts (L) and the support plate (M) as shown. • Fit the driver plate (B) on the drive shaft. • Rotate the drive shaft so that one of the holes in the driver plate lines up with the corresponding hole in the gear housing. • Insert the locking pin (C) into the hole to lock the shaft.
FUEL HANDLING Fuel mixture NOTE! The machine is fitted with a two-stroke engine and must always be run on a mixture of gasoline and two-stroke oil. It is important to measure the quantity of oil accurately, to ensure the correct mixture ratio. Small discrepancies in the amount of oil have a great bearing on the proportions of the fuel mixture when mixing small amounts of fuel. ! WARNING! Always provide good ventilation when handling fuel.
START AND STOP Control before starting For reasons of safety follow these recommendations! • Check the blade to ensure that no cracks have formed at the bottom of the teeth or by the centre hole. The most common reason why cracks are formed is that sharp corners have been formed at the bottom of the teeth while sharpening or that the blade has been used with dull teeth. Discard a blade if cracks are found. • Check that the support flange is not cracked due to fatigue or due to being tightened too much.
START AND STOP Stop The engine is stopped by switching off the ignition. ! 240R, 245R, 250R 245RX, 252RX, 265RX WARNING! When the engine is started with the choke in the choke or start position the cutting equipment starts to rotate immediately. Start Press the machine body against the ground using your left hand (NOTE! Not your foot). Grip the starter handle, slowly pull out the cord with your right hand until you feel some resistance (the starter pawls grip), now quickly and powerfully pull the cord.
MAINTENANCE Carburetor Basic setting Your Husqvarna product has been designed and manufactured to specifications that reduce harmful emissions. After your unit has been run 8-10 tanks of fuel the engine has broken in. To ensure that your unit is at peak performance and producing the least amount of harmful emissions after break in, have your authorized servicing dealer, who has a revolution counter at his disposal, to adjust your carburetor for optimum operating conditions.
MAINTENANCE Final setting of the idling speed T Correctly adjusted carburetor Adjust the idling speed with the screw T, If it is necessary to readjust. First turn the idle speed adjusting screw T clockwise until the cutting attachment starts to rotate/ move. Then turn, counterclockwise until the cutting attachment stops. A correctly adjusted idle speed setting occurs when the engine runs smoothly in every position. It should also be good margin to the rpm when the cutting attachment starts to rotate/move.
MAINTENANCE Muffler Cooling system NOTE! Some mufflers are fitted with a catalytic converter. See 240R, 245R/RX “Technical data” to see whether you clearing saw is fitted with a catalytic converter. The muffler is designed to dampen the noise level and to direct the exhaust fumes away from the user. The exhaust fumes are hot and can contain sparks, which can result in fire if the exhaust fumes are directed towards a dry and inflammable material.
MAINTENANCE Air filter The air filter should be cleaned regularly removing dust and dirt to avoid: • carburettor malfunction • starting problems • reduced engine power • unnecessary wear to engine parts • abnormal fuel consumption Oiling the air filter Always use HUSQVARNA filter oil, order no. 503 47 73-01. The filter oil contains a solvent to make it spread evenly through the filter. You should therefore avoid skin contact. Put the filter in a plastic bag and the pour the filter oil over it.
MAINTENANCE Angle gear Filing the grass blade ! The angle gear is filled with a sufficient quantity of grease at the factory. However, before using the machine you should check that the angle gear is filled to 3/4 with grease. Use HUSQVARNA special grease. Normally, the grease does not need to be changed except when the angle gear is repaired. WARNING! Always stop the engine before starting work on any part of the cutting equipment. This continues to rotate even after the throttle has been released.
MAINTENANCE Sharpening the clearing blade ! WARNING! Incorrect cutting equipment or an incorrectly sharpened blade increases the risk of kickback. • See the cutting equipment’s packaging for correct filing instructions. • Make sure that the blade is well supported when you use the file. Use a 5.5 mm round file with a file holder. • The sharpening angle is 15°. Every other tooth is sharpened to the right and the intermediate tooth to the left.
