    3 • INSTRUCTIONS FOR USE INDICATIONS FOR FIRST USE Make sure that the motorcycle’s “PRE-DELIVERY OPERATIONS” have been completed by your TM dealer. Carefully read all of the instructions before using the motorcycle for the first time. Familiarize yourself with all of the controls. Adjust the clutch lever, the front brake lever and the brake pedal to the most comfortable position. Practice riding the motorcycle in an empty car park or on easy terrain before going for a long drive. Also try standing up while riding slowly, to get a feel for how the motorcycle handles.

Make sure you do not press the brake pedal with your foot if you do not want to stop.

  • Page 42: Running-In Instructions

    3 • INSTRUCTIONS FOR USE RUNNING-IN INSTRUCTIONS The component surfaces of a new motorcycle, despite precision machining, are not as smooth as the components of motorcycles that have been running for a long time. This is why running-in a new motorcycle is so important. For optimal settling of moving parts, a new motorcycle must be brought to its maximum performance gradually. The main rules to follow are: 1. After cold start, warm up the engine for about 3 minutes before starting to use the motorcycle. 2. During the first 3 hours of use (1 hour for competitive use) the engine must be used only up to a maximum of 50% of its power. Plus, the number of revs must not exceed 6500 rpm. 3. During the subsequent 5 hours of use (1 hour for competitive use) the engine can be used up to a maximum of 75% of its power. Ride the motorcycle under a variety of conditions (road, easy off-road stretches). Do not go on long journeys without ever closing the throttle. Gradually increase and reduce throttle opening, alternating acceleration and deceleration with short periods at constant speed. Make sure that the coolant does not reach temperatures that are too high (indicated by fluid leaking from the bleeder hose). By following these rules, you will obtain maximum performance and longer engine life. It is essential that you carry out the operations described in the “Maintenance Schedule” during the running-in period. Be particularly careful when replacing oil as metal particles that can detach from the surfaces of engine parts in contact during running-in circulate in the oil and are deposited in the cap with magnet. Therefore, replacing oil and cleaning the cap with magnet allows these particles to be definitively removed from the engine. PRELIMINARY CHECKS In order to drive safely, the motorcycle must be in good condition and well maintained. It is good practice to perform a general check on the motorcycle before every use. It must include the following checks: - 2 stroke oil and fuel level check (EN - SMR) - brake fluid level check;...

  • Page 48: Stopping And Parking

    3 • INSTRUCTIONS FOR USE INFORMATION: Standard TM motorcycles are not equipped with radiator cooling fans and the radiator dimensions are designed for optimum compactness and weight. The cooling system is sufficient for tourist or sport use. Consult a TM dealer if you want to use optional cooling fans. WARNING Using the engine at high revs when it is still cold affects the length of engine life. Therefore, before running the engine at full speed, warm it up by driving a few kilometers at medium speed. The engine has reached its operating temperature as soon as the radiators become hot. Never down shift without having first slowed down. The engine revs would go too high and some of its components could be damaged. Also, the rear wheel could lock, causing you to lose control of the vehicle. If you feel abnormal vibrations while driving, make sure that the fixing screws on the motorcycle are fully tightened. - If you hear strange noises while riding your motorcycle, stop immediately, turn off the engine and contact a TM dealer. STOPPING AND PARKING With the throttle fully released, brake the motorcycle until it stops while pulling the clutch lever. Shift into neutral and release the clutch. Keeping the engine at idle speed, press button (1) (EN), button (2) (MX / SMK) or turn the key (3) (SMR / SMM) to the “ ” position to stop the engine. We recommend leaving the red engine start prevention button (4) (EN) pressed in until the next engine start. Park the motorcycle on solid ground and engage the steering lock, if present. DANGER DURING OPERATION, MOTORCYCLES PRODUCE A LOT OF HEAT.

  • Page 49: Washing

    3 • INSTRUCTIONS FOR USE WASHING - Regularly clean the motorcycle to keep the surface of plastic parts in good condition. - Use hot water, a cleaning product available on the market and a sponge. Heavy dirt can be removed with a gentle jet of water. - Plug the exhaust pipe before cleaning to prevent water from going in. - Remove the air filter as described in the “Maintenance” section. WARNING Do not aim water jets directly at the filter case (1), or water may enter the engine zone. Use cleaning products available on the market to wash the engine. Use a suitable brush to clean particularly dirty parts. - Once you have thoroughly rinsed the motorcycle with a gentle jet of water, dry with compressed air and a cloth. Immediately go for a short ride until the engine reaches the operating temperature and, at this point, also use the brakes. The water left in the areas that cannot be reached and on the brakes will evaporate thanks to the heat. Once the motorcycle has cooled down, oil or grease all sliding parts and bearings. Apply a specific spray to the chain. - Apply a specific spray for contacts to all the electrical controls on the handlebar and electrical system connectors to prevent faults in the electrical system.

  • Page 50: Storage

    3 • INSTRUCTIONS FOR USE STORAGE Take the following measures if the motorcycle is to be left unused for a long period: - Thoroughly clean the motorcycle (see “WASHING”). Change the gearbox oil. Old oil contains harmful impurities (see the “MAINTENANCE” section). Check the coolant level. Remove the spark plug and pour approx. 5 cc of engine oil into the cylinder through the spark plug hole. Activate the kick starter 10 times to allow the engine oil to be distributed on the cylinder wall. Then fit the spark plug again. - Compress the piston to make the exhaust ports close. Empty the fuel tank and collect the fuel in a suitable container. - Disconnect the cables and remove the battery. Plan a maintenance schedule if required. (SMR) - Adjust the tire pressure. Grease the bearings, control lever and footrest supports and the chain. - The storage area should be dry and not subject to drastic temperature changes. Cover the motorcycle, preferably with a breathable sheet or cover. Do not use airtight materials, as moisture would be trapped and could cause corrosion. Place the motorcycle on a stand, so that its wheels are raised off the ground.
