TYPICAL OPERATION

BOOSTER BATTERY CONNECTIONS TO MACHINE BATTERIES (JUMP START)

WARNING: Batteries contain acid and explosive gas. Explosion can result from sparks, flames or wrong cable connections. To connect the jumper cables correctly to the battery of this machine, see the correct method shown on this page. Failure to follow these instructions can cause serious injury or death.

WARNING: Battery explosion and/or damage to electrical components can result from improper connection of booster batteries or charger. Connect positive to positive and negative to negative. Externally, battery acid can cause burns and blindness, and taken internally it is poison.

Two persons are required for this procedure. Make sure the person making the connections is wearing face protection. NOTE: Make sure the batteries are not frozen. Do not use batteries that have been frozen. Replace the batteries if the batteries have been frozen. 1. Open the engine hood. Sit in the operators seat and have the other person make the connections. 2. Make sure the jumper batteries are 24 volts. 3. If using another machine for power, make sure the two machines DO NOT touch. 4. Connect the positive (+) jumper cable to the positive (+) battery terminals first. 5. Connect the negative (-) jumper cable to the negative (-) terminal on the jumper batteries on the other machine. Connect the other end of the negative (-) jumper cable to a good frame ground away from the batteries. 6. Start the engine according to the instructions in this manual. See Starting the Engine Using

Booster Batteries, in this manual. 7. Have the other person disconnect the jumper cables in the reverse order that they were connected in. Close the engine hood. 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). 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. NOTE: Do not use the starter for more than 15seconds without a pause of 30seconds to allow it to cool down. Observe all instruments for proper reading. 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. 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.

STARTING THE ENGINE

1.Start the engine and keep it running at one half speed for 3 to 4 minutes, before machine operation. 2. Do not accelerate the engine just after starting.

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.

CHANGING ENGINE SPEEDS

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. 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. The use of seat belts is always required, even on ROPS equipped machines. Before starting the machine, check, adjust and lock the operator’s seat assembly for maximum comfort and control of the machine. This machine is equipped with power steering which is effective only when the engine is running. If engine fails, stop the machine immediately. For emergency stops, apply foot brakes as required or pull parking/ emergency brake lever. Check the torque of the wheel bolts after every 20 hours of operation until the wheel bolts stay tight, if the machine is new or if a wheel has been removed and installed. Tighten according to procedure and specifications manual instructions. Always travel with the scarifier in the full raised position and lower to the ground when parked. Use extra care when using down pressure on the blade when working on hills, banks and slopes. NOTE: When the Motorgrader wheels have been turned to the maximum (in either direction), do not continue to turn the steering wheel in the same direction. This causes unnecessary wear on pump and valve components of steering system.. To start machine motion, raise moldboard, release parking brake, shift into the desired range and direction and move the throttle lever to meet the operational requirements. Range changes will be governed by the speed attained or desired. Select a transmission range that will maintain engine speed appropriate for the load required. Low engine speed can be corrected by downshifting or lightening the load. Over revving the engine should be avoided. Slow the machine by applying the brakes. Observe the following instructions: 1.Down shift only when the ground speed for the selected range has been achieved. 2.Down shift only one range at a time.

WARNING: Do not coast the machine at any time with the transmission in neutral. Do not attempt to decelerate on grades by shifting. Decelerate the engine and apply the foot brakes. Anticipate grades before starting down. Select the proper gear range to maintain the control. Engage transmission to start up only when the engine is at low idle. Down or up shift only one range at a time and only when the speed of the machine approximates the speed of the next range.

The transmission range and engine speed should be set before beginning the grading operation. Never overload the moldboard, so that the rear wheels begin to slip. This not only alters the grade but causes unnecessary wear to rear tires. Increasing the blade angle (putting one blade tip farther forward than the other tip) will reduce the load. The blade should be set to cast the dirt either inside or outside of the rear wheels, not under the wheels unless it is for compaction purposes. The moldboard pitch can be changed to suit various operations. When the top of the moldboard is tilted forward the cutting edge will not slice the material, but push it. This is advantageous when pushing dirt from one location to another. Tilting the top of the moldboard to the rear will angle the cutting edge so that it will slice and create a bite into the material. This can be advantageous in heavy material because the material will roll against the moldboard, breaking it up and making it easier to move. Using the moldboard to back drag material should be avoided if possible. This can cause heavy wear on the moldboard guides and possibly damage the side shift cylinder piston rod. If back dragging cannot be avoided, make certain material does not contact the positioning piston rod. Worn or poorly adjusted moldboard guides will cause an unstable moldboard for fine grading. When making heavy cuts or moving heavy loads that tend to side shift the Grader, lean the front wheels toward the load to counteract side shift. When starting a ditch, position moldboard so that one cutting edge (right or left) is directly behind and 3" (76 mm) below the front wheel, with the other end of the blade as high as possible. Cast the material between the rear wheels. The first cut should be light enough to maintain control of the grader and cut a straight ditch line. When the material accumulates under the machine, it should be cast aside before taking another cut in ditch line. Deeper ditch requires more side casting of material. If a “V” ditch is required, each side of the ditch must be cut alternately to permit the front and rear wheels to travel in the center of the ditch. When it is necessary to cast material over the edge of a fill, side shift the moldboard to its extreme, so that the grader wheels are not on edge of fill. The weight of the machine could cause the edge to give way endangering the operator. Articulation also helps in this situation. When grading a road shoulder, it may be necessary to grade around objects, such as mailboxes abutments or utility poles. The moldboard can be side shifted around the object without changing the grade level.
