PLATE 1177241 - Caterpillar

3. Gradually increase the engine speed to high idle. The machine should not move.
If the machine begins to move, reduce the engine speed immediately and engage the parking/secondary brake.
4. Reduce the engine speed to low idle, move the transmission to NEUTRAL. Engage the parking/secondary brake, lower the bucket to the ground and stop the engine.
If the machine moved while testing the brakes, contact your Caterpillar dealer. Have the dealer inspect and, if necessary, repair the service brakes before returning the machine to operation.
Test Parking/Secondary Holding Ability
Be sure the area around machine is clear of personnel and obstructions.Be sure the steering frame lock link is in stored position.Test the brakes on a dry, level surface.The following tests are to determine if the parking/secondary 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 rpm will vary from machine to machine due to differences in engine setting, power train efficiency, etc., as well as differences in brake holding ability.Engine rpm at beginning of machine movement, with parking/secondary brake applied, should be compared against the engine rpm your specific machine was able to hold on a prior test, as an indication of system deterioration. 1. Start the engine, and raise the bucket slightly. 2. With the parking/secondary brake engaged, move the transmission to 2nd speed reverse. 3. Gradually increase the engine speed to high idle. The machine should not move.
If the machine begins to move, reduce the engine speed immediately and apply the service brake.
4. Reduce the engine speed, move the transmission to NEUTRAL. Lower the bucket to the ground and stop the engine.
If the machine moved while testing the brakes, contact your Caterpillar dealer. Have the dealer inspect and, if necessary, repair the parking/secondary brakes before returning the machine to operation.
Cooling System
Add Liquid Additive
Do not add coolant additive until you read and understand the material in the "Cooling System Specifications" section.
The radiator cap access cover is located on the top of the hood at the left rear. 1. Open the hood access cover. 2. Remove the radiator cap slowly to relieve pressure.3. Add .25 liters (1/2 pint) of liquid coolant additive.4. Install the radiator fill cap and close the access cover.Drive Shaft Spline
Lubricate fitting
1. Disconnect the steering frame lock link. Start the engine.2. Turn the machine full right or left. 3. Lower the bucket, engage the parking/secondary brake and stop the engine. 4. Lubricate one fitting.Air Conditioner (If Equipped)
Test Operation - Adjust Belt
1. Start the engine. Operate the engine at high idle. 2. Set the air conditioner control for maximum cooling, and fan control on HIGH.3. Allow two minutes for the air conditioning system to stabilize. 4. Check for freon in the system as follows: Feel the suction line (1) and the discharge line (2).If the system contains freon, the discharge line will be warmer than the suction line.If the system does not contain, or is very low on freon, poor cooling will result.5.
