It is extremely important that you read and understand the content of this manual. • When using an edger, personal protective equipment approved by the appropriate authorities must be used.
SAFETY INSTRUCTIONS 4. Vibration damping system Your machine is equipped with a vibration damping system, which is designed to give as vibration-free and comfortable use as possible. The use of incorrect cutting equipment increases the level of vibration. The machine’s vibration damping system reduces the transfer of vibrations between the engine unit/cutting equipment and the machine’s handle unit.
SAFETY INSTRUCTIONS Control, maintenance and service of the machine’s safety equipment 3. Cutting attachment guard • Ensure that the guard is undamaged and is not cracked. IMPORTANT INFORMATION • All service and repairs to the machine require special training. • This applies especially to the machine’s safety equipment. If the machine does not meet any of the controls listed below you should contact your service workshop. • Replace the guard if it has been exposed to impact or is cracked.
SAFETY INSTRUCTIONS 6. Cutting equipment 7. Locking nut The two basic rules: • Protect your hand from injury when assembling, use the blade guard as protection when tightening with a socket spanner. Tighten the nut by turning against the direction of rotation. Loosen the nut by turning in the direction of rotation. (NOTE! the nut has a left-hand thread). 1. Only use the cutting equipment we recommend! See chapter “Technical data”. 2.
SAFETY INSTRUCTIONS General safety instructions IMPORTANT INFORMATION • The machine is only designed for cutting the edges of lawns. • The only accessories to be used with the engine unit as a drive source are the cutting units we recommend in the chapter “Technical data”. Safety instructions regarding the surroundings • Never allow children to use the machine. • Ensure no one comes closer than 15 metres when working.
SAFETY INSTRUCTIONS Start ! Fuel safety WARNING! When the engine starts with the choke lever in the choke or starter throttle position the cutting tool (blade or trimmer) starts to rotate immediately. • The complete clutch cover with shaft must be fitted before the machine is started, otherwise the clutch can become loose and cause personal injury. • Never start the machine indoors. Bear in mind the dangers of inhaling the engine’s exhaust fumes.

ASSEMBLY Assembling the loop handlebar • Position the handle on the shaft. Note that the handle must be mounted below the arrow on the shaft. • Fit the bolt, securing plate and wing nut as shown in the diagram. Assembling the blade Fit the blade as follows: 1. Fit the drive disc (A) on the outgoing shaft. Make sure that the edge that fits in the hole of the blade is facing outward. 2.
FUEL HANDLING Fuel mixture Mixture NOTE! The edger is fitted with two-stroke engines and must always be run on a mixture of gasoline and two-stroke oil. To ensure the correct mixture proportions it is important to measure the quantity of oil accurately. When mixing small amounts of fuel small discrepancies in the amount of oil has a great bearing on the proportions of the fuel mixture. • Always start by filling half the quantity of gasoline required. Then add the entire oil quantity.
START AND STOP Control before starting CHOKE: Set the choke control in the choke position. For reasons of safety follow these recommendations! • Check that the support flange is not cracked due to fatigue or due to being tightened too much. Replace the support flange if it is cracked. • Ensure that the nut has not lost its tightening capacity The nut lock shall have a locking torque of at least 1.5Nm. The nut‘s tightening torque shall be 35-50 Nm.
MAINTENANCE Carburetor 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 A correctly adjusted carburetor means that the machine accelerates without hesitation and the machine 4-cycles a little at max speed. Furthermore, the cutting attachment must not rotate/move at idling. A too lean adjusted low speed needle L may cause starting difficulties and bad acceleration. A too lean adjusted high speed needle H gives lower power = less capacity, bad acceleration and/or damage to the engine.
MAINTENANCE Muffler with catalytic converter Cooling system A muffler fitted with a catalytic converter reduces the extent of the following substances in the exhaust fumes: To maintain as low operating temperature as possible the engine is equipped with a cooling system. The cooling system consists of: • Hydrocarbons (HC). Some hydrocarbons in gasoline and the exhaust are carcinogenic. • Nitric oxides (NO). Irritating for the breathing air-ways. • Aldehydes.
MAINTENANCE Air filter The air filter should be cleaned regularly removing dust and dirt to avoid: • carburetor malfunction • starting problems • reduced engine power • unnecessary wear to engine parts • abnormal fuel consumption Clean the filter after every 25 hours or more regularly if operating conditions are exceptionally dusty. Cleaning the air filter Dismantle the air filter cover and remove the air filter. Wash in clean, warm soapy water. Ensure that the filter is dry before refitting.
MAINTENANCE NOTE: Use only HUSQVARNA replacement parts. Use of other brands of replacement parts can cause damage to your unit or injury to the operator or others. Your warranty does not cover damage or liability caused by the use of accessories and/or attachments not specifically recommended by HUSQVARNA. Maintenance schedule Below you will find some general maintenance instructions. Daily maintenance • Check throttle trigger and throttle trigger lockout function. • Check stop switch function.
