PLATE-PIN 5157906 - 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 brake before operating machine. Failure to release before operating will damage parking brake and could result in a runaway machine.
Attain desired travel speed before engaging the vibratory system. To achieve optimum compaction efficiency, low range should be used when compacting.Avoid using the leveling blade (if equipped) as plow or digging device. Machine damage may occur.Shut the vibratory system off when passing over concrete or hard pavement.
The bearings in the vibratory reservoir for the weight shaft are lubricated by rotating the drum assembly. Turning the vibratory system on with the machine not propelling may shorten the vibratory bearing life.
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. Move the propel control lever to forward or reverse.3. Start the vibratory system by pressing vibration on/off
