Winter | A winter diggers maintenance guide
Winter is coming and the cold is getting stronger. The low temperature environment not only tests the stamina of people, but also tests the "physique" of the excavator. How to get your equipment through the winter smoothly? What are the winter operational mistakes to avoid? Tweet to collect this guide!
01
Maintenance Instructions
Make butter in time.
Butter (grease) can effectively lubricate parts, reduce wear and prevent dust ingress. If not filled on time, it will reduce the sealing effect and accelerate the component loss. In winter, lubrication oil with a small viscosity should be chosen.
Choose the right oil.
Winter should choose a low freezing point , ignition performance of light diesel , as well as low freezing point of the oil , and at the same time to replace the oil filter . Hydraulic oil should also be selected according to the local minimum temperature .
Battery maintenance
At present, all of the batteries used by Sany are maintenance-free, but the low temperature in winter will greatly reduce the battery capacity. So try to park your car in a garage or a shelter after you stop.
In addition, it is necessary to avoid long-term power losses, and the vehicle should be turned off in time after the vehicle has stopped running. If the vehicle is not used for a long time (more than 2 weeks), it is recommended to start the vehicle at idle for 30 minutes each week to recharge the battery or use a dedicated charger to recharge.
Check the chassis
Regularly check whether the chassis bolts are loose, whether the pipes are leaking, and timely rust painting and buttering to ensure that the structure is intact.
Add antifreeze in moderation
Add a moderate amount of antifreeze to the cooling system, a ratio that should be taken into account of the local minimum winter temperature. Check whether the antifreeze is in normal condition before winter.
Glass is frozen to clean
Lift the rain brush to avoid freezing with the windshield. When cleaning the glass, antifreeze should be added to the water fountain to prevent ice formation.

Operational Precautions
Preheat before launch
It is strictly forbidden to directly operate without a heating machine, which mainly includes the heating of the engine and the preheating of hydraulic oil.After starting, first operate at a low speed not more than 5 minutes, then turn the fuel control knob to medium speed, operate empty for about 5 minutes, until the engine is fully preheated and the hydraulic oil preheated temperature > 45 ° before construction.
Forbidden from igniting open fires
Do not use flame ignite air filter or air inlet pipe combustion, so as to avoid impurities into the cylinder, aggravate the wear.
Baking oil shells is forbidden
Bake on open fire is easy to cause the oil to deteriorate, the lubrication performance to decline, and in severe cases, it may cause the equipment to be destroyed.
Avoid leaving cooling water too early
After the engine is stopped, it should idle until the water temperature drops below 60 ° C before releasing the water.The premature release of water will cause the body to crack sharply, and the remaining water to freeze will expand and damage the structure.
Dispose properly after downtime.
Do not park the excavator idly and ignore it after completing the job. Residues of mud on the fuselage may seep into the interior and cause damage if they come into contact with the seals. The right thing to do is to remove dirt and moisture from the surface of the airframe. Choose a hard, dry ground for parking; Empty moisture that may accumulate in the fuel system to prevent ice formation.
Winter is upon us, and carefully guard your armored companion to ensure the project progress and the safety of the equipment. Remember to forward a reminder to your fellow workers!
