3. Lubrication

Choosing a lubricant: to lubricate key details, such as the front connecting pin, a swivel bearing, a gear crown of a rotary mechanism and a central rotary hinge, use the Hitachi recommended lithium with anti -residual properties. This lubricant has good resistance to pressure and wear resistance, which allows you to effectively reduce the friction coefficient between moving parts and reduce wear.

Regular replenishment: regularly check and replenish the lubricant depending on the frequency of use and operating conditions of the equipment. For example, it is recommended to lubricate the pins of the working body after each working shift; The rotary support should be lubricated every 250 hours to guarantee the constant presence of lubrication in all components and extend their service life.

4. Air filter service

The function of the air filter is to prevent dust and other contaminants in the engine and the deterioration of its operation. Regular cleaning or replacing the air filter is extremely important. During operation in conditions of increased dusting, the frequency of examinations and maintenance should be increased. If the filter is strongly clogged, it should be immediately replaced to ensure smooth air intake, effective combustion of fuel, increased fuel economy and prevent increased engine wear due to excessive pollution.

5. The service of the cooling system

Cleaning and removing the scale: regularly clean the cooling system to prevent the accumulation of scale and pollution in the cooling system and the deterioration of heat transfer. You can use a special cleaning tool for the cooling system using the specified method and proportion.

Replacement of coolant: when replacing the coolant, the car must be installed on a flat surface to ensure safe operation. In this case, the coolant and the anti -corrosion agent should be selected in strict accordance with the standards, and the ratio of the components should also be observed. In winter, special attention should be paid to the addition of antifreeze in order to prevent the freezing of the coolant and damage to the cooling system.

6. Carling of the electric system

Carefully check the integrity of electrical circuits, make sure that there are no damage, wear, short circuits, etc., as well as that the power plug is reliably inserted into the outlet. Regularly check the level of electrolyte in the battery to make sure of its normal level. If the level is insufficient, share distilled water. In addition, check the electrodes of the battery for corrosion. In the event of its presence, immediately clean them and apply a protective lubricant to ensure stable power supply of the electrical system and avoid failures in power supply affecting the normal operation of the equipment.

7. Care the teeth and levers of the bucket.

The teeth and hilt of the bucket are components directly involved in the process of earthwork, and their condition directly affects the effectiveness and results of digging. Spend the teeth of the bucket for wear regularly. Strong wear of teeth increases the resistance of digging, fuel consumption and can even reduce performance. Replace the teeth immediately. Also inspect the bucket hilt for the presence of cracks, deformations and oil leaks. If there are any malfunctions, immediately repair or replace them to ensure safe and reliable operation.
