SHAFT GP-DRIVE 1175772 - Caterpillar

Operating Technique Information
Operate the engine at full rpm for maximum braking, steering and propel control response. Operation below full throttle will adversely affect response.When climbing steep grades, the propel control lever must be moved SLOWLY to avoid engine stall and possible loss of machine control.
Release parking/secondary brake before operating machine. Failure to release before operating will damage parking/secondary brake and could result in a runaway machine.
Attain desired travel speed before engaging the vibratory system.Avoid using the leveling blade (if equipped) as plow or digging device. Machine damage may occur.Do not operate vibratory system at less than 1800 vpm.Shut the vibratory system off when passing over concrete or hard pavement.Begin the first compaction pass along the side of the work with subsequent passes gradually working towards the center. Overlap the previous pass by approximately 200 mm (7.75 in) to eliminate uncompacted strips.
Before changing the vibratory amplitude selection, the system should be completely stopped.
Vibratory Operation - High Amplitude
Placing the vibratory system in high amplitude increases the total dynamic force and height of drum movement on each vibration cycle.High amplitude is used whenever:* The job site requires higher compaction forces to meet density requirements.* The lift or depth of material to be compacted is 254 mm (10.0 in) or more. High amplitude can cause material to break down if passes continue to be made once the specified density has been achieved. Every jobsite is different due to soil conditions, such as moisture content and material. To determine the amplitude and the number of passes required, establish a test plot at each jobsite. 1. Place vibratory system in high amplitude by moving vibratory control switch (1) backward.2. Start the vibratory system by pressing vibration on/off switch (2) on top of the propel control lever.3. Stop the vibratory system by pressing vibration on/off switch (2). Moving vibratory control switch (1) to the off position will also stop the vibratory system. If decoupling (separation of the drum from the material being compacted) occurs, select low amplitude.Vibratory Operation - Low Amplitude
Placing the vibratory system in low amplitude decreases the total amount of force and height of drum movement on each vibration cycle.Low amplitude is used whenever:* Compaction densities have not been reached and drum decoupling occurs.* The lift thickness is less than 254 mm (10.0 in).* Objects such as sewer and water systems may be damaged due to the higher compaction forces of high amplitude.1. Place vibratory system in low amplitude by moving vibratory control switch (1) forward.2. Start the vibratory system by pressing vibration on/off switch (2) on top of the propel control lever.3. Stop the vibratory system by pressing vibration on/off switch (2).
