Product Operate Guide
Before operation, wrap the machine around for inspection to ensure there are no abnormalities. Start the engine and let it idle for preheating. Select the vibration mode and amplitude (use high amplitude and low frequency for initial pressure, and low frequency and high frequency for re-pressure). Start slowly, change direction smoothly and avoid sudden stops. The final pressure is turned off and the vibration is turned off for static pressure surface finishing. Before shutting down, let the machine idle for cooling and carry out regular maintenance.
FAQ
1.In what working conditions is the double steel wheel roller mainly used?
A: It is mainly used for the compaction of asphalt pavement, including the initial compaction, re-compaction and final compaction of the base layer and surface layer. It is a core equipment for the construction of high-grade highways, airports and municipal roads.
2.How should the vibration mode be selected (high amplitude/low amplitude)?
A: High amplitude is used for the initial compaction of thick layers or materials that are difficult to compact; Low amplitude is used for thin layering, final compaction or compaction with particle size restrictions on the material to achieve a smoother surface.
3.What items need to be checked before starting up daily?
A: Check the levels of engine oil, coolant and fuel. Check the hydraulic oil level; Check if there is any adhered asphalt on the steel wheel. Check whether the sprinkler system is functioning properly. Walk around the vehicle to check for any oil or water leakage.
4.What is the maintenance cycle for vibrating bearings and vibrating wheels?
A: Replace the grease of the vibrating bearing strictly in accordance with the time specified in the operation manual (usually calculated by working hours). Operation without lubrication is strictly prohibited. Keep the steel wheels clean to prevent the long-term adhesion of asphalt from affecting the balance.
5.Is the vibration system (vibration valve/motor) the main maintenance point? How often should the hydraulic oil be changed?
A: Yes, the vibration hydraulic system is the core. The hydraulic oil and filter element should be replaced after the first 500 hours. Under normal circumstances thereafter, they should be replaced every 1,000 hours. If the working environment is harsh, the oil change cycle should be appropriately shortened.
6.What type of engine oil and diesel should be used for the engine?
A: Please select the engine strictly in accordance with the requirements of the engine brand's manual (Shanghai/Weichai).
Engine oil: Generally, 15W-40 diesel engine oil of CF-4 or above grade is recommended.
Diesel: Only clean diesel that meets national standards, such as 0# or -10#, must be used. The selection should be based on the ambient temperature. The use of inferior diesel is strictly prohibited.
