How to maintain bulk feed carriers in winter
In winter, the temperature is low. In order to make the bulk feed truck run safely and reliably, maintenance work should be done in place. Here we have compiled some information on the winter maintenance of bulk feed trucks, hoping to bring help to car owners. 1, the battery check, to ensure the power supply requirements In addition to the appearance of the battery clean maintenance, but also check the electrolyte level; can determine the degree of discharge of the battery through the density of the electrolyte, maintenance-free battery can be viewed by its built-in Density meter to determine the state of the battery, when the winter discharge of more than 25% should be charged in a timely manner, otherwise it will shorten the test battery life, resulting in early damage. 2. Check the engine of the starter and check whether the connection terminals of the starter are connected firmly. The engine with preheating device should be used to warm up the engine before starting in winter and then start the engine. The starter should not be powered for too long. The starting of the brush holder should ensure freedom of movement and there should be no jamming, otherwise it needs to be adjusted or replaced. The contact area between brush and commutator should not be less than 75%, otherwise it can be sanded or replaced with sandpaper. Including engine belts, if worn, etc. should be replaced immediately. 3, electrical harness inspection loose aging problems Winter temperatures are low, the vehicle's electrical circuit is very easy to rain and ice, resulting in insulation damage, the wire is broken by ice phenomenon. In addition, key sensors and electronic control units should also be reinforced to prevent damage caused by water ice. 4, antifreeze check all kinds of errors should pay attention to ethylene glycol in the antifreeze, and ethylene glycol on the metal has a certain degree of corrosion, need to add antiseptic in the antifreeze. Some antifreezes will fail the antifreeze and anticorrosion indicators at the factory. Some antifreezes will gradually be oxidized and decay as the use time is prolonged, and the antiseptics will continue to be consumed; when the antifreeze quality drops to a certain degree, Afterwards, the cooling system will be corroded or fail to meet antifreeze requirements. Therefore, in order to ensure the quality of antifreeze, quality testing must be performed before and during use. 5, thermostat inspection not to lose a lot of cars because of the heavy load of high temperature, the thermostat will be removed, but in the winter, if the vehicle does not have a thermostat or thermostat non-normal work, it will Slow down the engine warm-up process, increase engine wear, especially the electronically controlled engine. After the thermostat is removed, the engine is at a low temperature level and the fuel consumption will increase. In addition, the thermostat also affects the normal use of the warm air system. If the vehicle does not have a thermostat or the thermostat is damaged, replace the safety thermostat with a new one. 6. Inspection of the oil system must be both anti-frost and safe. Diesel oil contains paraffin wax, which dissolves in diesel oil at normal temperatures and acts as a lubricant for the fuel pump and injector of diesel vehicles. Once the temperature is lowered, paraffin is Crystals will begin to precipitate, and then the crystals of each unit will polymerize to form a "paraffin crystal network." This network extends into all liquids and completely controls the diesel fuel, causing the diesel to lose its fluidity and clogging the filter screen, affecting normal oil supply. 7, the brake system can not be sloppy to check a comprehensive and reliable braking system In addition to the inevitable check brake pad thickness, adjust the brake gap, the gas tank should pay attention to regularly check the discharge, replace the dry cans on time. The exceptions need to pay attention to check whether the air compressor has any phenomenon such as stringing oil. If it is abnormal, it should be repaired or replaced in time to ensure the safe and effective operation of the braking system.

Benefits:
The effectiveness is tender, balanced. Effectively improve the pliability and fullness of the leathers, increase the yield of leather output. When used in Wet-Blue reconditioning, it promotes the absorption of tanning agent and improve the dyeing uniformity, it has very good permeability, evenly soften effect can be obtained. Its use will not lead to loose grain on leather.
This product should be stored in a cool and dry place in sealed container, avoiding insolation, high temperature and damp. The product has been formulated for optimal stability. Extended storage or adverse conditions such as higher temperature or higher humidity may lead to a higher dosage requirement.
Enzyme preparations are proteins, which may induce sensitization and cause allergic type reactions in sensitized individuals. Prolonged contact may cause minor irritation for skin, eyes or nasal mucosa, so any direct contiguity with human body should be avoided. If irritation or allergic response for skin or eyes develops, consult a doctor.
