PRELIMINARY INSPECTION

CAUTION

By resolving rapidly all of your machine problemas, you will reduce maintenance and downtime. It is advisable that you check your machine every morning, prior to starting the days work. 1- Check for worn, damaged, or excessively over or under inflated tires.

2 - Check for damaged or warn wind screen blade or blade ends.

3 - Check for cooling system leaks or damaged hoses.

4 - Check for any tandem leaks.

5 - Check if the circle needs adjustment.

6 - Check for damaged parts or failed displays in the operator´s cab.

7 - Check for leaks

8 - Check for leaks or damaged hoses in the hydraulic system.

ALSO CHECK AS FOLLOWS

Electrical system Check for damaged insulators, and loose wires and connections

Bolts Check for loose or missing components

Hydraulic system Check for leaks, twisted hoses and flexible lines or tubes contacting other parts

Lubrication Check lube points as shown in the periodic maintenance chart

OPERATION

Turn the master battery switch located in the inside rear of the cab to ON. Pull throttle lever to the position if the engine is cold (1/4 open if the engine is warm).

Turn the key switch to the "ON" position. When the engine starts, release the key. Pull the hand throtlle immediately to the idling position. Then, move the throttle lever to the midway speed position. Hold halfway of the maximum speed, until the temperature gauge needle moves from minimum.

NOTE: Do not crank the starter motor for more than 30 seconds at a time without a 2 minute pause to allow the motor to cool down. Watch all instruments.

It is extremely important to leave the engine running for 3 to 5 minutes with the throttle lever at 1/4 to 1/ 2 of full travel, to allow the lubricating oil to warm up and circulate freely. This procedure is recommended in cold weather.

Check engine lubricating oil pressure. With the engine running at high idle and coolant at normal operating temperature, oil pressure should be within normal operating limits. When the oil is cold, there will be no pressure indication on the display for a few seconds after the engine has been started. If the pressure does not raise to normal or above normal after a few seconds, stop engine immediately. Investigate the cause of the problem and correct. Check transmission fluid pressure gauge. After a few seconds after starting the engine, the transmission oil needle should be inside or close to the green zone. DURING ENGINE STARTING

1 - Before starting the engine, start with the fuel shut off for 10 to 15 seconds, or until the instruments show sufficient oil pressure.

2- Start and run engine in low idle for 3 to 4 minutes before accelerating.

3- Do not increase engine speed after starting to prevent lack of lubrication of the turbocharger bearings.

DURING ENGINE STOPPING

Prior to switching off the engine, run it for a few minutes in low idle to allow the turbocharger to declerate and stabilize at a low operating speed. Avoid high speeds during engine stopping to prevent damage to the turbocharger bearing due to lack of lubrication. If the engine is abruptly switched off in high speed, the turbocharger will continue turning after the engine oil pressure drops to "ZERO". Operating at high speeds with lack of oil, the turbocharger bearings may be damaged in a matter of seconds.

ENGINE SPEED CHANGE

Prolonged use of engine idling will cause coolant temperatures to drop below the operating limit.

Provided the engine is running, there is no reason for prolonged idling. Switch off the engine when this occurs. However, if it is necessary to keep the engine running, it shall have adequate speed to keep engine oil pressure and coolant temperature. Move gear selector lever to neutral, and engage the parking brake. Lower the blade to the ground. Do not abandon the machine.
