OPERATION TO START ENGINE (See Fig. 3) The Briggs & Stratton Endurance engine equipped with your tractor features a Ready-Start automatic choke system to provide simplified starting in normal conditions. Please read the following starting instruction carefully. 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 control to "DISENGAGED" position. NORMAL STARTING (32°F/0°C and above) • Move throttle control to fast position ( ) and click into place. • Insert key into ignition and turn key clockwise ( ) to "START" position and release key as soon as engine starts. • When engine starts, the attachments and ground drive can now be used. If the engine does not accept the load and shuts off, restart the engine and allow it to warm up for one minute. • Leave throttle control in fast position ( ) while mowing. COLD WEATHER STARTING (32°F/0°C and below) • Move throttle control beyond fast position into the cold weather starting position ( ). CAUTION: Do not run starter continuously for more than fifteen seconds per minute. If the engine does not start after several attempts, wait a few minutes and try again. • Insert key into ignition and turn key clockwise to "START" position and release key as soon as engine starts. • When the engine starts, move the throttle control back to the fast position ( ) to warm-up. The time required for warm-up will vary from a few seconds to a minute depending upon conditions and temperature. • Leave throttle control in fast position ( ) while mowing. AUTOMATIC TRANSMISSION WARM UP • Before driving the unit in cold weather, the transmission should be warmed up as follows: • Ensure 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 also be used during the engine warm-up period after the transmission has been warmed up. PURGE TRANSMISSION CAUTION: Never engage or disengage freewheel lever while the engine is running. To ensure proper operation and performance, it is recommended that the transmission be purged before operating tractor for the first time. This procedure will remove any trapped air inside the transmission which may have developed during shipping of your tractor. IMPORTANT: SHOULD YOUR TRANSMISSION REQUIRE REMOVAL FOR SERVICE OR REPLACEMENT, IT SHOULD BE PURGED AFTER REINSTALLATION BEFORE OPERATING THE TRACTOR. 1. Place tractor safely on a level surface - that is clear and open - with engine off and parking brake set. 2. Disengage transmission by placing freewheel control in disengaged position. (See "TO TRANSPORT" in this section of manual.) 3. Sitting in the tractor seat, start engine. After the engine is running, move throttle control to slow position. Disengage parking brake CAUTION: At any time, during step 4, there may be movement of the drive wheels. 4. Depress forward drive pedal to full forward position, hold for five (5) seconds and release pedal. Depress reverse drive pedal to full reverse position, hold for five (5) seconds and release pedal. Repeat this procedure three (3) times. 5. Shut- off engine and set parking brake. 6. Engage transmission by placing freewheel control in engaged position. (See "TO TRANSPORT" in this section of manual.) 7. Sitting in the tractor seat, start engine. After the engine is running, move throttle control to half (1/2) speed. Disengage parking brake. 8. Drive tractor forward for approximately 5 feet (1,5 m) then backwards for 5 feet (1,5 m). Repeat this driving procedure three times. Your transmission is now purged and now ready for normal operation. HOUR METER The hourmeter shows the total number of hours the engine has run.
