SAFETY INSTRUCTIONS Personal protective equipment IMPORTANT! Whenever you use a clearing saw, brushcutter or trimmer you must wear personal protective equipment that is approved by the authorities. Personal protective equipment does not eliminate the risk of accidents, but it can reduce the effects of an injury in the event of an accident. Ask your dealer for help when choosing protective equipment. ! WARNING! Listen out for warning signals or shouts when you are wearing hearing protection.
SAFETY INSTRUCTIONS ! WARNING! Never use a cutting attachment without an approved guard. See the chapter on Technical data. If an incorrect or faulty guard is fitted this can cause serious personal injury. Muffler The muffler is designed to keep noise levels to a minimum and to direct exhaust fumes away from the user. A muffler fitted with a catalytic converter is also designed to reduce harmful exhaust gases.
SAFETY INSTRUCTIONS Grass blades and grass cutters are intended for cutting coarse grass. • Check that the throttle control and throttle lock move freely and that the return springs work properly. • The throttle lock is designed to prevent accidental operation of the throttle control. When you press the lock (A) (i.e. when you grasp the handle) it releases the throttle control (B). When you release the handle the throttle control and the throttle lock both move back to their original positions.
SAFETY INSTRUCTIONS • Always use the recommended guard for the cutting attachment you are using. See chapter on Technical data. Cutting equipment This section describes how to choose and maintain your cutting equipment in order to: Vibration damping system • • • Reduce the risk of kickback. • Obtain maximum cutting performance. • Extend the life of cutting equipment. General rules 1 Only use cutting attachments with the guards we recommend! See the chapter on Technical data.
SAFETY INSTRUCTIONS Locking nut • • • Make sure that the blade is well supported when you file it. Use a 5.5 mm round file with a file holder. • The filing angle is 15°. File alternate teeth to the right and those in between to the left. If the blade has been heavily pitted by stones it may be necessary to dress the top edges of the teeth with a flat file, in exceptional cases. If so, this should be done before filing with a round file.
SAFETY INSTRUCTIONS • • • • Smaller machines generally require small trimmer heads and vice versa. This is because when clearing using a cord the engine must throw out the cord radially from the trimmer head and overcome the resistance of the grass being cleared. The length of the cord is also important. A longer cord requires greater engine power than a shorter cord of the same diameter. Make sure that the cutter on the trimmer guard is intact. This is used to cut the cord to the correct length.
SAFETY INSTRUCTIONS Transport and storage • 4 Take great care when cutting a tree that is in tension. A tree that is in 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. Both situations can cause serious personal injury. 5 Switch off the engine before moving to another area.
SAFETY INSTRUCTIONS Spreading the load on your shoulders A well-adjusted harness and machine makes work much easier. Adjust the harness for the best working position. Tension the side straps so that the weight is evenly distributed across both shoulders. Basic working techniques • Always slow the engine to idle speed after each working operation. Long periods at full throttle without any load on the engine can lead to serious engine damage.
SAFETY INSTRUCTIONS The ABC of clearing Forestry clearing using a saw blade Always use the correct equipment. Make sure the equipment is well adjusted. Follow the safety precautions. • The risk of kickback increases with increasing stem size. You should therefore avoid cutting with the area of the blade between 12 o’clock and 3 o’clock. • To fell to the left, the bottom of the tree should be pushed to the right. Tilt the blade and bring it diagonally down to the right, exerting firm pressure.
SAFETY INSTRUCTIONS side. Adjust the cutting pressure to match the size of the stem and the hardness of the wood. Small stems require more pressure, while large stems require less pressure. • If the stems are tightly packed, adapt your walking pace to suit. • If the blade jams in a stem, never jerk the machine free. If you do this the blade, bevel gear, shaft or handlebar may be damaged. Release the handles, grip the shaft with both hands and gently pull the machine free.
SAFETY INSTRUCTIONS Grass trimming with a trimmer head • Trimming Do not allow the trimmer head to constantly come into contact with the ground during normal cutting. Constant contact of this type can cause damage and wear to the trimmer head. Sweeping • Hold the trimmer head just above the ground at an angle. It is the end of the cord that does the work. Let the cord work at its own pace. Never press the cord into the area to be cut.

ASSEMBLY Fitting the handlebar Fitting the handlebar (232R) (235R) • Remove the screw at the rear of the throttle handle. • Remove the screw at the rear of the throttle handle. • Slide the throttle handle onto the right side of the handlebar, (see diagram). • Slide the throttle handle onto the right side of the handlebar, (see diagram). • Align the screw hole in the throttle handle with the hole in the handlebar. • Align the screw hole in the throttle handle with the hole in the handlebar.
ASSEMBLY Transport position, handlebar • Fit the drive disc (B) on the output shaft. • • Turn the blade shaft until one of the holes in the drive disc aligns with the corresponding hole in the gear housing. • Insert the locking pin (C) in the hole to lock the shaft. • Place the blade (D), support cup (E) and support flange (F) on the output shaft. • Fit the nut (G). The nut must be tightened to a torque of 35-50 Nm (3.5-5 kpm). Use the socket spanner in the tool kit.
ASSEMBLY • Insert the locking pin (C) in the hole to lock the shaft. • • Place the blade (D) and support flange (F) on the output shaft. To fit the trimmer head, first separate the two halves (see diagram). Proceed as follows: • Insert a finger into the centre hole of the cover (I) while grasping the cover with your other fingers. Using the index finger and thumb of your other hand, release the two catches (J) that engage in the cut-outs in the bottom half (K).

B C Correct height M 1 • Fit the trimmer guard/combination guard (A) intended for use with the trimmer head/plastic blades.
FUEL HANDLING Fuel Two-stroke oil CAUTION! The machine is equipped with a two-stroke engine and must always been run using a mixture of gasoline 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.
FUEL HANDLING Fuelling ! WARNING! Taking the following precautions, will lessen the risk of fire: Do not smoke or place hot objects near fuel. Always shut off the engine before refuelling. 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. Tighten the fuel cap carefully after refuelling. Always move the machine away from the refuelling area before starting.
STARTING AND STOPPING Check before starting • 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.
STARTING AND STOPPING Air purge: Press the air purge diaphragm repeatedly until fuel begins to fill the diaphragm. The diaphragm need not be completely filled. Stopping Stop the engine by switching off the ignition. ! WARNING! When the engine is started with the choke in either the choke or start throttle positions the cutting attachment will start to rotate immediately. Starting Hold the body of the machine on the ground using your left hand (CAUTION! Not with your foot!).
MAINTENANCE Carburettor Your Husqvarna product has been designed and manufactured to specifications that reduce harmful emissions. After the engine has used 8-10 tanks of fuel the engine will be run-in. To ensure that it continues to run at peak performance and to minimise harmful exhaust emissions after the running-in period, ask your dealer/service workshop (who will have a rev counter at their disposal) to adjust your carburettor.
MAINTENANCE High speed jet H Note that the engine should not be under load when you adjust the high speed jet H. You should therefore remove the cutting attachment, nut, support flange and drive disc before adjusting the high speed jet H. The high speed jet H affects the engine power, speed, temperature and fuel consumption. If the high speed jet H is set too lean (screwed in too far) the engine speed will be too high and cause engine damage. Do not let the engine run at full speed for more than 10 seconds.
MAINTENANCE Bevel gear The bevel gear is filled with the right quantity of grease at the factory. However, before using the machine you should check that the bevel gear is filled three-quarters full with grease. Use HUSQVARNA special grease. Put the filter in a plastic bag and pour the filter oil over it. Knead the plastic bag to distribute the oil. Squeeze the excess oil out of the filter inside the plastic bag and pour off the excess before fitting the filter to the machine. Never use common engine oil.
MAINTENANCE • Sharpen all edges equally to maintain the balance of the blade. ! WARNING! Always discard a blade that is bent, twisted, cracked, broken or damaged in any other way. Never attempt to straighten a twisted blade so that it can be reused. Only use original blades of the specified type. Daily maintenance • Check throttle trigger and throttle trigger lockout function. • Check that the stop switch works correctly. • Check that the cutting attachment always stops when the engine is idling.
