OPERATING INSTRUCTIONS
OPERATING INSTRUCTIONS Turn master switch key, located in operator’s compartment to the “ON” position. Pull throttle lever back to full speed position if engine is cold (1/4 speed position, if engine is warm).
STARTING THE ENGINE
Turn ignition key to the start position. When the engine starts, release the key. Immediately pull throttle lever into low idle. Then set at one half speed. Maintain one half maximum speed until coolant temperature gauge needle moves from its minimum position.
2. Do not accelerate the engine just after starting.
1. Start the engine and keep it running at one half speed for 3 to 4 minutes, before machine operation. STOPPING THE ENGINE Before shutting down the engine, keep it running a few minutes at low idle speed to permit turbo charger deceleration and stabilization at a low speed. Avoid shutting off the engine at a high speed, because the turbocharger shaft bearings will be damaged due to poor lubrication.
NOTE: Do not use the starter for more than 30 seconds without a pause of two minutes to allow it to cool down. Observe all instruments for proper reading.
CHANGING ENGINE SPEEDS
It is extremely important to allow the engine to run for three to five minutes at 1/4 to 1/2 throttle to permit the lubrication oil to warm and circulate freely through the bearings. This procedure is mandatory for cold weather operation.
Prolonged engine idling causes engine coolant operating temperature to fall below operating range. Since engines are readily started, there should be no reason for prolonged engine idling. However, if it is necessary to keep the engine running, run at a speed fast enough to maintain normal oil pressure and engine coolant temperature. Place the transmission control lever in the neutral position and apply the parking brake. Lower the moldboard to the ground. Do not leave the machine unattended.
Check engine lubricating oil pressure. With engine running at high speed and the coolant at normal operating temperature, oil pressure must be within normal operating range. When the oil is cold no pressure may be indicated on the gauge for several seconds after the engine starts. If the pressure does not rise to normal or above, after a few seconds, the engine must be stopped immediately and the cause determined and corrected. Check the transmission fluid pressure. Within a few seconds after the engine starts the transmission oil pressure gauge must register in or near the green range.
This machine and its attachments are to be operated only by a qualified operator stationed at the operator’s controls either seated or standing as conditions require.
