Ding, warm reminder letter for the use of road machinery products and winter maintenance~

Dear Customers,

     Thank you for using the Sany machine equipment, in order to make your equipment operate normally in winter, please follow the following operations for maintenance:

road rollerMilling machineIn winter ambient temperature<0℃Use the spraying system under operation, spray with warm water first, and then use water to spray after the ambient temperature rises;

After use, the sprinkler head and filter element should be removed, and the water in the pipe and water tank should be blown clean with an air pump to prevent damage to the spraying system parts caused by the freezing of the water remaining in the spraying system.

After each use, the water pump should be unplugged from the water suction and drainage hose (water pump inlet and outlet pipes) and the water pump should be started.10After a few seconds, the pump will automatically stop and start the pump again,10After a few seconds, the pump stops again, so that the water in the pump can be drained. (Do not start and stop the pump more than once, and the single idling time should not be exceeded.)15seconds)

Drain the water in the filter cup of the oil-water separator to prevent the filter cup shell from freezing and cracking due to excessive water content in the filter cup.

The ambient temperature in winter is-20℃and below, when the parking time is exceeded1When it is more than a month old, please put down the antifreeze in the engine water pump and radiator, connect it with a clean bucket, and add it in the spring of the following year or replace the new antifreeze directly according to the maintenance cycle.

It is not allowed to add water to the antifreeze or mix different types of antifreeze.

The equipment is over15Keep the battery surface clean and dry, and it is strictly forbidden to place conductive objects on the battery to prevent the battery from losing power in the next use.

(Note: During the disassembly and assembly process, the tool should not directly touch the positive and negative terminals and cause a short circuit in the battery; When removing the battery, the negative terminal connection wire should be removed first, and the positive electrode should be connected first during installation. ）

The ambient temperature is lower0℃time, use-10 Number or-35diesel (to prevent diesel from being unable to start at low temperature wax multiple times, resulting in battery power loss);

And it is recommended to use winter low-temperature engine oil (10Wor5Wlevel), use-45Antifreeze and hydraulic oil are usedHM46Number;

Before starting the equipment in an extremely hot environment, the engine oil pan is heated by plumbing or fire baking, and the equipment is run slowly after the hydraulic oil temperature rises, and the hydraulic action is carried out after the hydraulic oil temperature reaches the operating requirements.

Winter equipment is over1When parked outdoors for a long time for a month or more, the equipment needs to be covered with a cover cloth to prevent snow and water from causing damage to equipment parts;

Fill up the fuel tank-10diesel to avoid rust in the fuel tank, and preservatives should be added if conditions permit;

Apply butter to the exposed parts of the equipment screed, cylinder and other parts to prevent rust. Seal the engine's air intakes and exhaust ports with plastic bags when parked indoors。
