In addition to reducing the risk of an explosion, using nitrogen instead of air to inflate tires lessens the slow oxidation of the rubber and the accompanying gradual tire deterioration. This is especially important for tires that have an expected long service life (4 or more years). It also reduces the corrosion of rim components and the resultant disassembly problems.Because a fully charged nitrogen cylinder's pressure is approximately 15 000 kPa (2200 psi), a tire blowout and/or rim failure can occur if the inflation equipment is not used correctly. See "Nitrogen Inflation Information," which follows.Nitrogen Inflation Information
Stand behind the tread when inflating a tire.
Set the tire inflation equipment regulator at no more than 140 kPa (20 psi) over the recommended tire pressure.
Use only a Caterpillar Part Number 6V4040 Nitrogen Tire Inflation Group, or equivalent, to inflate tires from a nitrogen gas cylinder. See Caterpillar "Special Instruction," Form Number SMHS7867 for tire inflation instructions.Use the same tire pressures for nitrogen inflation as would be used for air inflation. Consult your tire dealer for operating pressures.Emergency Exit
Use the sliding window on the right side of the cab as an emergency exit. Unlatch the window and slide it to the rear.Backup Alarm
The backup alarm, located at the rear of the scraper, sounds to warn nearby personnel of machine movement. The alarm should sound any time the transmission control is moved to REVERSE position, when the disconnect switch is ON. Adjust the alarm sound level to (1) HIGH, (2) LOW or (3) MEDIUM, to meet job requirements.The alarm is usually set at the (1) HIGH sound level when the machine is shipped from the factory.Seat Belt
Replace the seat belt or mounting hardware if they are damaged or worn. Replace the belt at least every three years.Adjust and fasten the seat belt before operating the machine.
Inspect for worn or frayed webbing. Check for worn or damaged buckle or anticreep slide, on each half of the belt. Replace the belt, buckle or slides if they are worn or damaged. Inspect the belt mounting hardware. Replace any worn or damaged hardware.
If the bolt and nut that holds the two parts of the seat belt mounting hooks together are not correctly installed, the hooks can separate from their mounting.Inspect the hooks of each half of the belt to make sure the bolt and nut are secure and correctly installed. See illustration.
Adjust both ends of the belt. The belt should be snug but comfortable.To Lengthen the Belt
1. With the belt unfastened, move the anticreep slide toward the buckle. 2. To remove the slack in the outer loop, rotate the buckle to free the lock bar. This permits the belt to move through the buckle.3. Pull on the buckle until the outer and inner belt loops are tight. 4. Loosen the other half of the belt in the same manner. Readjust the belt if it does not fit properly with the buckle in the center.To Shorten the Belt
1. With the belt fastened, pull on the outer loop to
