Maintenance

IMPORTANT Regular, careful maintenance is essential for keeping the safety level and original performance of the machine unchanged in time.
• Keep all nuts, bolts and screws tight to be sure the equipment is in safe working condition. Regular maintenance is essential for safety and performance.
• Never store the equipment with fuel in the tank inside a building where vapour may reach a flame or a spark or a source of extreme heat.
• Allow the engine to cool before storing in an enclosed space.
• To reduce the fire hazard, keep the engine, exhaust silencer, battery compartment and fuel storage area free of grass, leaves, or excessive grease. Do not
leave containers with grass cuttings in rooms.
• For reasons of safety, do not use the equipment with worn or damaged parts. Parts are to be replaced and not repaired. Use genuine spare parts (blades
should always bear the symbol). Parts that are not of the same quality can damage the equipment and be dangerous for your safety.
• If the fuel tank has to be drained, this should be done outdoors and when the engine is cool.
• Wear strong work gloves when removing and reassembling the blade.
• Check the blade's balance after sharpening.
• Check the self-closing guard and grass-catcher frequently for wear and deterioration.
• Whenever the machine is to be handled, transported or tilted you must:
- Wear strong working gloves;
- Grasp the machine at the points that offer a safe grip, taking account of the weight and its distribution.
Blade
Inspection
• Tilt the mower to the right, so the air cleaner side is up. This will help to prevent fuel leakage and hard starting.
• Inspect the blade for damage, cracks and excessive rust or corrosion.
A dull blade can be sharpened, but a blade that is excessively worn, bent, cracked, or otherwise damaged must be replaced.
• A torque wrench must always be used when installing the blade.
Check that the blade bolts are tight.
Removal and installation (Picture Q)
If you remove the blade for sharpening or replacement, you will need a torque wrench for installation. Wear heavy gloves to protect your hands.
• Remove the bolt with a socket wrench. Use a wooden block to prevent the blade from turning when removing the bolt. Then remove the blade.
• Install the blade using the blade bolt and special washers. Be sure to install the special washers with the concave side toward the blade and the convex side
toward the bolt.
• Tighten the blade bolt with a torque wrench. Use a wooden block to prevent the blade from turning when tightening the bolt.
Grass Bag Cleaning and Replacement (Picture R)
Cleaning
Wash the bag with a garden hose, and allow it to dry completely before use; a wet bag will clog quickly.
Replacement
• Unclip the plastic edges of the bag from the frame, remove the bag from the upper cover.
• Insert the fabric bag into the upper cover, clip the plastic edges of the bag onto the frame.
Water Nozzle (Picture R2)
• The left side of the mower deck is fitted with a water nozzle for washing the deck.
• When using the water nozzle, the machine must be in the lowest height position and placed on the lawn. This ensures that the water remains under the
deck during cleaning.
• Attach a hose to the nozzle.
• Turn on the water and start the engine.
• The rotations of the blades will ensure that the water will clean the underside of the deck.
Note: Not all models have water nozzle.
