Product Introduction
As major machine for shaping and leveling operation in earthwork engineering, motor grader is widely used for large ground (such as road and airport) and leveling operation of stable layer. With the constant expansion of its functions and development of its high-efficiency over the years, motor grader is applied to bulldozing and spreading of open-pit and roadbed mixture as well trimming of original landform. Besides, it can be applied to snow removing in cold region. Featuring 260HP power, strong strength of machine components and sufficient driving force, GR2605 is a heavy-duty motor grader research and developed especially for high-load working condition.
Product Advantage
Utilizing load sensitive hydraulic system, small control force, good control feeling, more sensitive. Engine variable power control technology, more energy efficient. Intelligent fan control technology enables fan speed changing with the real-time detected system temperature, low energy consumption and low noise. Two Electric joysticks control. The Joysticks can control all cylinders,steering,gear selection,differential Lock/Unlock, etc. The rear axle with oil bathed, multi-disc service brakes, has long lifetime and higher reliability.

Product Operate Guide
Before starting the operation, check the oil level gauge to ensure that the equipment is in normal condition. After starting, idle for preheating and operate the single-rod hydraulic handle to control the movement and the blade. Finely adjust the Angle and height of the scraper to level it. Be careful to avoid obstacles and drive slowly and prudently when working on slopes. Before parking, the shovel touches the ground and the engine is turned off. Strictly abide by safety regulations.
FAQ
1.What type of transmission system does it use? What are the benefits?
A: It adopts hydraulic mechanical transmission. This system combines the high efficiency of mechanical transmission with the stepless speed regulation feature of hydraulic transmission, providing greater traction force, smoother operation and better fuel economy. It is particularly suitable for heavy-load operations.
2.Is it easy to slip when working on muddy or soft ground?
A: The standard rear-wheel drive already has good performance, but customers can choose the all-wheel drive (all-wheel steering) function as an option. In harsh working conditions, enabling all-wheel drive can significantly enhance grip and passability, effectively prevent skidding, and improve the ability to get out of difficult situations.
3.How comfortable is the driving operation?
A: The cab is spacious, well-sealed, equipped with air conditioning and shock-absorbing seats. The operation handle is ergonomically designed with a wide field of vision, which can effectively reduce the fatigue caused by long-term driving.
4.Is daily maintenance and upkeep convenient?
A: The design is very easy to maintain. The engine hood can be opened at a large Angle for convenient maintenance. The most important thing is that it is equipped with a centralized lubrication system as standard. Just add grease at one point, and it can quickly complete the lubrication of multiple important hinge points, saving time and effort and effectively extending the service life of the equipment.
5.What should I do if an alarm indicator light appears on the instrument panel during work?
A: Work should be stopped immediately. Refer to the manual to confirm the meaning of the alarm. Common ones include engine oil pressure alarm, excessively high water temperature alarm, etc. If it cannot be solved by yourself, you should immediately turn off the engine and contact the after-sales service personnel.
6.What could be the reasons for feeling that the vehicle is weak or moving slowly?
A: There could be many reasons, for example:
Engine fuel system issues (such as clogged filters, etc.).
Hydraulic system issues (insufficient hydraulic oil, clogged filter element, internal leakage in the system).
Improper operation (setting the gear too high).
It is recommended to start with simple checks (such as oil and filter elements). If the problem persists, it should be repaired by a professional technician.
