2. Be extra cautious when driving on slopes Safety Instructions Children Serious accidents may occur if you fail to be on guard for children in the vicinity of the machine Children are often attracted to the machine and mowing Never assume that children will stay put where you last saw them Keep children away from the mowing area and under close supervision by another adult Keep an eye out and shut off the machine if children enter the work area Before and during a reversing manoeuvre look backward and downward for small children Never allow a child to ride with you They can fall off and seriously injure themselves or be in the way for safe manoeuvring of the machine Never allow children to operate the machine Be particularly careful near corners bushes trees or other objects that block your view Maintenance 10 Stop the engine Remove the ignition key before making any adjustments or carrying out maintenance Never fill the fuel tank indoors Only store fuel in clean containers approved for the purpose Never remove the fuel cap or fill the fuel tank with fuel while the engine is running Allow the engine to cool before refuelling Do not smoke Handle oil oil filters fuel and the battery carefully of environmental considerations Observe applicable recycling regulations Do not allow compressed air to come into contact with skin If compressed air penetrates the skin seek m
3. OOo 6 Maintenance 2 Maintenance and replacement are required more often in dusty conditions 3 With daily use the machine shall be lubricated twice weekly Performed by authorised service workshop After the first 25 hours AN WARNING No service operations may be performed on the engine or cutting unit unless e The engine is stopped e The parking brake is on e The ignition key has been removed Cleaning Clean the machine directly after use It is much easier to wash off grass cuttings before they dry Oily dirt can be removed using a cold degreasing agent Spray a thin layer and wait a few minutes Rinse at normal water pressure Do not direct the jet towards electrical components or bearings Do not rinse hot surfaces for example the engine and exhaust system IMPORTANT INFORMATION Avoid using a high pressure washer or a steam cleaner Lubricate the machine if necessary after cleaning Carry out extra lubrication when the bearings have been exposed to a degreaser or a water jet There is a major risk of water penetrating into bearings and electrical connections Corrosion attack which will lead to running problems Cleaning additives generally aggravate the damage Check and clean if dirt collects in the area for the circuit card and on the circuit card Clean using a dry method i e with a vacuum cleaner or compressed air Do not blow directly on the circuit card Do
4. Adjusting the parking brake Brake adjustment should be carried out by a Husqvarna workshop A WARNING A poorly adjusted parking brake can result in reduced braking ability Raise the machine so that the wheels rotate freely 2 When the parking brake has been released check that partial braking of the front wheels does not occur 3 Check that the braking effect is even and that the wheels stop with normal pedal travel p EN AS u o by Muffler Parking brake control 39 Maintenance 4 Check that the pedal can be locked in the applied position with normal pedal force 5 Adjust as necessary using the wires adjuster screws R and L Servicing the air filter If the engine seems to lack power or does not run smoothly this may be because the air filter is clogged When driving with a dirty air filter the engine does not receive enough air which does not meet the environmental demands and the engine does not operate at full efficiency It is important to replace the air filter regularly see See Maintenance Schedule on page 35 for the proper service interval Emptying the particle trap Compress so that the rubber tabs open and any particles can drop out Particle trap on air filter Cleaning the cyclone filter Remove the cover held in position by two brace locks and clean the inside of the cover Wash with soap water and blow dry using co
