ENGINE AR-COMPL 10R7692 - Caterpillar

Hydraulic System
Check Oil Level
The hydraulic oil tank is located on the right rear of the machine.1. Maintain the oil level to the FULL mark on the sight gauge. 2. Remove the oil fill cap and add oil, if necessary, through the fill tube.3. Clean and install the fill cap.Radiator
Check Coolant Level
1. The radiator cap is located in the top hood of the machine at the left front. Open the access door. 2. Remove the radiator cap slowly to relieve pressure.3. Maintain the coolant level to within 13 mm (.50 in) of the bottom of the fill pipe. If it is necessary to add coolant daily, check for leaks.4. Inspect the cap and cap seal for damage, deposits or foreign material. Clean the cap with a clean cloth or replace the cap if it is damaged.5. Install the cap.6. Close the access door.7. Inspect the radiator core for debris and clean if necessary.Compressed air is preferred, but high pressure water or steam can be used to remove dust, leaves, and general debris from a radiator. Clean as required by condition of radiator.Fuel Tank
Drain Water and Sediment
Drain valve is located at the left rear of the machine under the fuel tank.
D3C Series III Drain Valve
D4C and D5C Series III Drain Valve1. Open the drain valve and allow the water and sediment to drain. For a D4C Series III and a D5C Series III use a 7B-7908 pipe if necessary. The pipe is 114 mm (4.5 in) long with a 1 inch NPT pipe nipple.2. Close the drain valve.Water Separator
Drain Water and Sediment
The engine should never be allowed to run with the water level in the separator more than 1/2 full or engine damage may result.
The water separator is not a filter. It separates water from the fuel. 1. Open the access door located on the rear of the machine.2. Drain water from the separator daily before starting the engine. Close the supply line (if equipped). 3. Open vent valve (1) and drain valve (2). Allow the water to drain.4. Close vent valve (1), drain valve (2), and open the supply valve (if equipped).5. Close the access door.Indicators and Gauges
Test for Proper Function
Look for broken gauge lenses or indicator lights, switches, etc.Start the engine.Check and repair any oil leaks around covers or hoses.Look for inoperative gauges.Turn all machine lights on. Check for proper operation.Sound the forward horn.Stop the engine.Make any needed repairs before operating.Brakes
Test
Personal injury can result if the machine moves while testing.If the machine begins to move during test, reduce the engine speed immediately and engage the parking brake.
Be sure the area around machine is clear of personnel and obstructions.Test the brakes on a dry, level surface.Fasten the seat belt before testing the brakes.The following tests are to determine if the service brake is functional. These tests are not intended to measure maximum brake holding effort. Brake holding effort required to hold a machine at a specific engine speed varies from machine to machine due to differences in engine setting,
