FILLER GP-POWER TRAIN OIL 3600222 - Caterpillar

Automatic Retarder Control (ARC) (2) - Push the top half of the switch to select the ON position for the ARC system. This action allows the machine to maintain a constant downhill speed. Push the bottom half of the switch to select the OFF position for the ARC system. When the proper gear is selected during ARC operation, vehicle speed and engine speed will be automatically regulated. If necessary, use the manual retarder control to apply more retarding force during the operation of ARC.The ARC should remain in the ON position during normal operation. When you place switch (2) in the OFF position, the ARC will not control engine speed during normal operation. However, if the engine speed becomes too high, the ARC will perform engine overspeed protection.Engine Overspeed Protection
This machine is equipped with automatic engine overspeed protection. If the engine speed reaches 2475 rpm, the ARC system will automatically engage, regardless of the position of the ARC switch. To prevent further engine overspeed, the transmission will upshift one gear if the following conditions are met:
Engine speed reaches an unsafe engine speed.
For the engine overspeed rpm of your machine, refer your machine Changing Direction and Speed, "Operator Controls".
Transmission is in the same actual gear as the selected gear on the transmission control.Retarding Guidelines (Film)
Retarding performance charts provide an indication of the energy absorption capability of a given truck powertrain on a specified continuous, and less than 610 m (2000 ft) decline. Retarding performance charts serve to indicate the correct transmission gear selection and ground speed that should be used on a given grade to avoid situations which may result in machine overspeed and damage to the machine. Retarding performance charts do not give an indication of the ability of the truck to stop or the ability of the truck to remain stationary on the grades that are listed on the chart.

Maximum Operating Weight - The maximum operating weight of a loaded Off-Highway Truck
Transmission Gear for the Downgrade - The selected gear for downhill travel
Downhill Slope Percentage - The percentage value of the slope for downhill travel
Distance of the Downgrade - The distance of the slope for downhill travel The retarding capabilities that are listed on this film are based on an ambient temperature of 32 °C (90 °F).The actual retarding capabilities for each gear will vary depending on the following conditions:
Outside temperatures
Rolling resistance
Load
Cooling system condition
Tire size
AltitudeRetarding Information and Operation
Selection of the proper gear is essential for effective operation of the retarder system. Refer to the film for retarding guidelines to select the proper gear.Select the proper gear on the transmission control before you start down the grade. The actual gear should also match the selected gear before you start down the grade. For more information on the transmission control, refer to Operation and Maintenance Manual, SEBU8561, "Operator Controls".When the film does not address the current conditions, use the following
