Product Operate Guide
Intelligent power management: The engine of XLZ2103E features three power regulation curves, which can be switched instantly according to heavy-load, light-load and transfer conditions. This means that during regeneration operations, a high-power mode can be selected to ensure power supply, and when transferring sites, an economy mode can be switched to reduce fuel consumption. It is very intelligent and environmentally friendly.
• Flexible steering system: Its steering system supports multiple modes such as front-wheel steering, rear-wheel steering, all-wheel steering and crab driving. The rear wheels also have an automatic centering function. This makes the machine extremely flexible and easy to operate in narrow construction sites, capable of easily handling various complex working conditions.
• Precise water spraying control: The quality of water spraying is directly related to the compaction degree of the recycled layer. The water pump of this machine has a self-priming function and can be seamlessly connected with various water trucks. Through the control knobs on the instrument panel, the amount of water sprayed can be precisely adjusted to ensure that the mixture reaches the optimal moisture content, thereby guaranteeing the construction quality.
FAQ
◦ A: Please check in the following order:
■ Power supply system: Check whether the battery power is sufficient and whether the terminals are tight and free from corrosion.
■ Safety interlock device: Confirm that all control levers are in the "neutral" or "stop" position and the cab door is closed.
■ Fuel system: Check the fuel level in the fuel tank and confirm whether there is air in the fuel line (you can try to empty it by hand pump).
■ Electrical circuit: Check whether the fuse has blown and whether the starter circuit is reliably connected.
◦ A: This is the core intelligent function of the XLZ2103E. Please select according to the working conditions:
■ Heavy Load Mode (P1) : Suitable for hard road surfaces, maximum milling depth, and high-load operation conditions. The engine operates at rated power to ensure maximum power output.
■ Standard Mode (P2) : Applicable to general subgrade conditions and normal operation depth, it is a commonly used mode that takes into account both efficiency and economy.
■ Economy/Transfer Mode (P3) : Suitable for light-load mixing, equipment idling or transfer, the engine operates in the most fuel-efficient state, significantly reducing fuel consumption.
◦ A: The most common reason is:
■ Water source issue: Check the water level in the water tank and confirm that the valve of the water supply cart has been opened.
■ Filter screen/nozzle blockage: Check whether the inlet filter screen and outlet nozzle of the water pump are blocked by impurities and need to be cleaned regularly.
■ System intake: Check whether the connection points of the pipelines are tightly sealed. The self-priming function of the water pump can be utilized for exhaust.
■ Electrical control: Check whether the sprinkler switch and the flow setting value on the control panel are correct.
◦ A: Possible causes include:
■ Uneven tire pressure: Check whether the air pressure of the four tires is consistent and meets the standard.
■ Abnormal hydraulic system: Check whether the working pressure of the walking pump and motor is within the normal range.
■ Excessive load: Whether the currently set milling and mixing depth is too deep or the pavement material is abnormally hard, the operation parameters should be appropriately adjusted.
■ Improper steering mode: In complex road conditions, try switching different steering modes (such as crab lane) to improve passability.
◦ A: The following should be carried out before and after work every day:
■ Machine winding inspection: Check for oil leakage and whether the bolts of each component are loose.
■ "Three Oils and One Water" inspection: engine oil, hydraulic oil, coolant levels, and gear oil level of the reducer.
■ Cleaning work: Clean the dust and debris on the engine radiator, hydraulic oil radiator and air conditioning condenser.
■ Tool inspection: Inspect the wear condition of the rotor tools and replace the damaged tools in time.
■ Replacement standard: No fixed time, depending on the amount of work and the hardness of the road surface.
When the wear of the cutting tool exceeds one third of its original length or the tip is damaged, it must be replaced.
■ Replacement method: Use special tools and tighten them in the diagonal sequence one by one to ensure uniform torque. Avoid striking directly with a heavy hammer to prevent damage to the knife holder.
