Reasons And Solutions For Difficult Start Of Road Rollers in Winter 2

1. The quality of fuel oil is too poor
the
When the temperature of low-quality diesel oil is low in winter, there are many impurities in the oil that are less than the standard purity, resulting in unsmooth fuel supply and clogging of the fuel supply system by solid paraffin in the oil pipe. In this case, you only need to drain the fuel and add high-quality diesel.
2. Antifreeze problem
the
The antifreeze ratio is 50% when leaving the factory, and it can adapt to a low temperature of -40°. If you find it difficult to start, you must first check the antifreeze liquid level and engine oil level to see if it is caused by oil leakage or insufficient antifreeze.
the
3. Valve clearance is too large or too small
the
If the valve clearance is too small, it may cause air leakage, power drop, severe ring burning and carbon deposition on the sealing surface of the valve, and even the impact of the valve on the piston. If the gap is too large, the engine intake will be insufficient, the exhaust will not be clean and the power will be reduced. Incorrect valve clearance size will also make it difficult to start the roller, so this aspect also needs to be checked.
the
4. Throttle lever failure
the
The throttle lever cannot be adjusted, resulting in excessive oil supply, or insufficient oil supply, resulting in difficulty in starting the roller. Check whether the throttle rod firmware is intact, and check whether the throttle cable can be pulled after troubleshooting. If it cannot be pulled, the water in the cable tube may freeze, if it can be pulled but there is no rebound, the throttle cable may be disconnected and needs to be replaced.
