I. Pre-operation Preparation and Inspection
1. Equipment Verification: Confirm that the power unit, vibration mechanism, and tamping plate are securely connected; fuel, lubricating oil, and hydraulic oil levels are within acceptable limits; pipelines are free of damage and leaks; and tighten all loose bolts and components.
2. Site Clearance: Remove stones, rebar, tree roots, and other hard objects from the construction area. Level any uneven areas beforehand to prevent damage to the tamping plate or impaired compaction.
3. Personnel Protection: Operators must wear non-slip gloves, goggles, and protective shoes. Earmuffs should be worn to reduce vibration and noise damage. Loose clothing is prohibited to prevent entanglement in the machinery.
II. Operating Procedures
1. Start-up and Operation: Place the equipment on a stable surface. After starting, allow it to idle until the vibration is normal before commencing operation. Hold the control levers with both hands and keep your stance away from the tamping plate to avoid foot injuries.
2. Construction Parameter Control: Maintain soil moisture at 25%-30%; both excessive dryness and wetness will reduce compaction quality. Keep the travel speed moderate to avoid imbalance from excessive speed and energy waste from excessive slowness. Maintain a 1/3 overlap between adjacent compaction zones to prevent missed compaction. Thicker backfill soil requires layered compaction, with each layer not exceeding 30cm in thickness to avoid insufficient compaction depth in a single pass.
3. Working Condition Adaptation Requirements: Operation is prohibited in water or areas with slopes exceeding 20°. On slopes, construction must proceed parallel to the slope to prevent equipment tipping or slippage. Continuous operation should be limited to 30-60 minutes per session. Periodically stop the machine to allow for cooling and prevent overheating damage. Before switching forward/reverse gears on hydraulic machines, the vibration switch must be turned off and the throttle reduced. Switching gears while the machine is vibrating is prohibited.
III. Post-Operation Maintenance and Storage
1. Shutdown Procedure: First, turn off the vibration function. Let the machine idle for 2-3 minutes before turning off the power source. Do not shut down the machine directly.
2. Daily Cleaning: Promptly remove dirt and debris adhering to the tamping plate and vibrating components. Inspect the wear of the eccentric blocks and shock-absorbing pads, and clean any residual soil from the gaps in the pads.
3. Long-Term Storage: Move the equipment to a dry, well-ventilated indoor location. Elevate the tamping plate with wooden supports to prevent prolonged pressure. Seal the oil inlet and provide protection against rain, sun, and freezing to prevent rust and aging of components.
IV. Safety Red Line Requirements
Working is prohibited in flammable and explosive areas and in confined, poorly ventilated spaces. Warning signs must be posted in the work area. Unauthorized personnel are strictly prohibited from entering the work area. If any abnormal noises or loosening of the equipment are detected, the machine must be stopped immediately for inspection. Forced operation is strictly prohibited.
