Husqvarna YT48CS Operation Manual - Page 12

OPERATION BEFORE STARTING THE ENGINE CHECK ENGINE OIL LEVEL The engine in your tractor has been shipped from the factory already filled with summer weight oil. • Check engine oil with tractor on level ground. • Remove oil fill cap/dipstick and wipe clean, reinsert the dipstick and screw cap tight, wait for a few seconds, remove and read oil level. If necessary, add oil until "FULL" mark on dipstick is reached. Do not overfill. • For cold weather operation you should change oil for easier starting. (See "OIL VISCOSITY CHART" in the Maintenance section of this manual.) • To change engine oil, see the Maintenance section in this manual. ADD GASOLINE • Fill fuel tank to bottom of filler neck. Do not overfill. Use fresh, clean, regular gasoline with a minimum of 87 octane. Do not mix oil with gasoline. Purchase fuel in quantities that can be used within 30 days to ensure fuel freshness. CAUTION: Wipe off any spilled oil or fuel. Do not store, spill or use gasoline near an open flame. IMPORTANT: WHEN OPERATING IN TEMPERATURES BELOW 32°F (0°C), USE FRESH, CLEAN WINTER GRADE GASOLINE TO HELP ENSURE GOOD COLD WEATHER STARTING. CAUTION: Alcohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. To avoid engine problems, the fuel system should be emptied before storage of 30 days or longer. Drain the gas tank, start the engine and let it run until the fuel lines and carburetor are empty. Use fresh fuel next season. See Storage Instructions for additional information. Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur. Fuel stabilizer is an acceptable alternative in minimizing the formation of fuel gum deposits during storage. Add stabilizer to gasoline in fuel tank or storage container. Always follow the mix ratio found on stabilizer container. Run engine at least 10 minutes after adding stabilizer to allow the stabilizer to reach the carburetor. Do not empty the gas tank and carburetor if using fuel stabilizer. TO START ENGINE (See Fig. 3) When starting the engine for the first time or if the engine has run out of fuel, it will take extra cranking time to move fuel from the tank to the engine. • Ensure freewheel control is in the transmission engaged position. • Sit on seat in operating position, depress brake pedal and set parking brake. • Move attachment clutch to "DISENGAGED" position. • Move throttle control to fast position • Pull choke control out for a cold engine start attempt. For a warm engine start attempt the choke control may not be needed. NOTE: Before starting, read the warm and cold starting procedures below. • Insert key into ignition and turn key clockwise to "START" position and release key as soon as engine starts. Do not run starter continuously for more than fifteen seconds per minute. If the engine does not start after several attempts, push choke control in, wait a few minutes and try again. If engine still does not start, pull the choke control out and retry. WARM WEATHER STARTING (50°F/10°C and above) • When engine starts, slowly push choke control in until the engine begins to run smoothly. If the engine starts to run roughly, pull the choke control out slightly for a few seconds and then continue to push the control in slowly. • The attachments and ground drive can now be used. If the engine does not accept the load, restart the engine and allow it to warm up for one minute using the choke as described above. COLD WEATHER STARTING (50°F/10°C and below) • When engine starts, slowly push choke control in until the engine begins to run smoothly. Continue to push the choke control in small steps allowing the engine to accept small changes in speed and load, until the choke control is fully in. If the engine starts to run roughly, pull the choke control out slightly for a few seconds and then continue to push the control in slowly. This may require an engine warm-up period from several seconds to several minutes, depending on the temperature. AUTOMATIC TRANSMISSION WARM UP • Before driving the unit in cold weather, the transmission should be warmed up as follows: • Be sure the tractor is on level ground. • Release the parking brake and let the brake slowly return to operating position. • Allow one minute for transmission to warm up. This can be done during the engine warm up period. • The attachments can be used during the engine warmup period after the transmission has been warmed up and may require the choke control be pulled out slightly. 12
