To get a good cutting result

  • For best performance, do maintenance on the product regularly as given in the maintenance schedule. Refer to Maintenance schedule on page 98.

  • Do not cut a wet lawn. Wet grass can give a bad cutting result.

  • Cut with blades that rotate at high speed (highest permitted engine speed, refer to Technical data on page 115). Move the product forward at low speed.
    If the grass is not too high and thick, you can get a good cutting result also at a higher speed.

  • Cut the grass in an irregular pattern.

  • To get the best cutting result, cut the grass frequently and use the BioClip function.

To attach load to the engine cover
The product has rails and rail brackets on the engine cover to attach load.

  1. Adjust the rail brackets to fit the load.
    a) Loosen the screw and move the rail bracket forward or rearward on the rail.Husqvarna R 318X Rider R 318x Lawn Tractor - rail
bracketb) Tighten the screw.

  2. Put a strap through the hole in the rail bracket (A).Husqvarna R 318X Rider R 318x Lawn Tractor - rail bracket1

To clean the product
CAUTION: Do not use a high-pressure washer or a steam cleaner. Water can go into bearings and electrical connections and cause corrosion which causes damage to the product.

Clean the product immediately after use.

  • Do not clean hot surfaces such as the engine, muffler and exhaust system. Wait until the surfaces are cool, then remove the grass or dirt.

  • Before you clean with water, clean with a brush.
    Remove grass cuttings and dirt on and around the transmission, the transmission air intake, and the engine.

  • Use running water from a hose to clean the product.
    Do not use high pressure.

  • Do not point the water at electrical components or bearings. Detergent usually increases the damage.

  • To clean the cutting deck, put it in the servicing position and clean it with a water hose.

  • When the product is clean, start the cutting deck for a short period to blow off remaining water.Husqvarna R 318X Rider R 318x Lawn Tractor - remaining water

To clean the engine and the muffler
Keep the engine and muffler free from grass cuttings and dirt. Grass cuttings soaked in fuel or oil on the engine can increase the fire risk and the risk that the engine becomes too hot. Let the engine cool before it is cleaned. Clean with water and a brush.
Grass cuttings around the muffler dry quickly and are a fire risk. Use a brush or remove the grass cuttings with water when the muffler is cold.

To clean the cold air intake of the engine
WARNING: Stop the engine. The cold air intake rotates and can cause injury to your fingers.

  • Make sure that the intake grille on the engine cover is not blocked. Remove grass and dirt with a brush.Husqvarna R 318X Rider R 318x Lawn Tractor - engine cover
  • Open the engine cover. Make sure that the engine cold air intake is not blocked. Remove grass and dirt with a brush.Husqvarna R 318X Rider R 318x Lawn Tractor - with a brush

To charge the battery

  • Charge the battery if it is too weak to start the engine.

  • Use a standard battery charger.
    CAUTION: Do not use a boost charger or start booster. That will cause damage to the electrical system of the product.

  • Always disconnect the charger before starting the engine.

To do an emergency start of the engine
If the battery is too weak to start the engine, you can use jumper cables to do an emergency start. This product has a 12 V system with negative ground. The product that is used for the emergency start must also have a 12 V system with negative ground.

To connect the jumper cables

To tow the product
The product has a hydrostatic transmission. To prevent damage to the transmission, tow the product short distances only and at low speed.
Disengage the transmission before you tow the product.
Refer to To engage and disengage the drive system on page 95.
Storage
Prepare the product for storage at the end of the season, and before more than 30 days of storage. If you keep fuel in the fuel tank for 30 days or more, tacky particles can cause blockage in the carburetor. This has a negative effect on the engine function.
To prevent tacky particles during storage, add a stabilizer. If alkylate gasoline is used, stabilizer is not necessary. If you use standard gasoline, do not change to alkylate gasoline. This can cause sensitive rubber parts to become hard. Add stabilizer to the fuel in the tank or in the container used for storage. Always use the mixing ratios given by the manufacturer. Run the engine for a minimum of 10 minutes after you add the stabilizer until it flows into the carburetor.

WARNING: Do not keep the product with fuel in the tank in an indoor location or in locations with bad airflow. Risk of fire if fuel fumes come near open flames, sparks,
or pilot lights in for example boilers, hot water tanks and clothes dryers.
WARNING: Remove grass, leaves and other flammable materials from the product to decrease the risk of fire. Let the product become cool before you put it in storage.

  • Clean the product, see To clean the product on page 100. Repair paint damages to prevent corrosion.

  • Examine the product for worn or damaged parts and tighten loose screws and nuts.

  • Remove the battery. Clean it, charge it, and keep it cool during storage.

  • Change the engine oil, and discard the waste oil.

  • Empty the fuel tank. Start the engine and run it until there is no remaining fuel in the carburetor.
    Note: Do not empty the fuel tank and carburetor if a stabilizer has been added.

  • Remove the plugs and put about a tablespoon of engine oil into each cylinder. Manually turn the engine shaft to apply the oil and put the plugs back on.

  • Lubricate all grease nipples, joints and axles.

  • Keep the product in a clean and dry area and cover it for more protection.

  • A cover for protection of your product during storage or transport is available at your dealer.

Disposal

  • Chemicals can be dangerous and must not be discarded on the ground. Always discard used chemicals at a service center or an applicable disposal location.
  • When the product is worn out, send it to the dealer or to an applicable recycling location.
  • Oil, oil filters, fuel and the battery can have negative effects on the environment. Obey the local recycling requirements and applicable regulations.
  • Do not discard the battery as domestic waste.
  • Send the battery to a Husqvarna service agent or discard it at a disposal location for used batteries.
