Inspection of excavator before operation

A New Year，A new journey。Work is about to start.，The excavator can't come up and strike a fire.，No less inspection before commencement，Today, I will send you a guide to the physical examination of excavators.。

Pre-start check

01

Check around the car

When the excavator is parked for a long time and then started，Don't rush to start the vehicle.。Check around the car first.，Check whether the bolts of each part are loose.，Are parts missing or damaged；Open the door panel and observe whether there is any foreign matter inside.；Check whether the oil cylinder piston rod is bumped.，Sealing kit for oil leakage；Check each stress point of the boom and arm，Whether there is cracking and deformation；Check the grease of each connecting pin，Whether there is deterioration or missing。

02

Check the oil

Check the oil、Hydraulic oil、Fuel oil、Is there any change in the quality of gear oil?，Whether the oil level is sufficient；Add grease to each pin and lubrication point，If necessary, squeeze the old oil out of the oil passage；Check whether the grease of swing support is sufficient；Check the coolant，Check whether the coolant is deteriorated，Is the water tank damaged or leaking；Check the urea liquid level for the model with urea aqueous solution、Leakage and crystallization。

03

Check the belt

Check the belt of each part，Physical examination of excavator，Small details can not be let go.。Especially look at the fan belt.、Engine belt and air conditioning compressor belt，Whether it is intact and tensioned。

04

Check the filter element

Check the cleanliness of the excavator radiator，Avoid high temperature caused by clogging of radiator vent，Damage to engine。If there is a blockage，Please clean it in time。Check whether the air filter element is blocked or broken，Excessive amount of external filter dust，Clean with compressed air machine，The inner filter can only be replaced。

05

Check the battery

Check whether the battery and the surrounding harness are loose or damaged.。If the battery has been removed prior to shutdown，Ensure that the battery has sufficient power before installation.、Power is off。

Pay attention to rotating the main power switch handle to“ON”Bit，Energize the excavator，After the display is started，Check whether the display parameters are normal.，Whether there is fault code, etc.；At the same time，The light switch should be checked、Whether the functions of air conditioning control panel and multimedia are normal。

Check after startup

06

Preheat

If the above checks are all right.，Start the engine，Idle first 3-5 minutes，And get off to check whether there is oil leakage on the appearance of the equipment.、Leakage、Abnormal sound、Abnormal smoke color, etc.！In the absence of the above，Operate each action slowly with no load for preheating.，Until the hydraulic oil temperature increase；Check the throttle、Whether the functions such as automatic idle speed are abnormal。If there is no problem with the warm-up and inspection after startup，You can work normally.！

These are the main points of excavator inspection before the Spring Festival.。Pass these checks，We can ensure that the excavator is in the best condition for the new work cycle.。Finally，Here I wish you all good luck in digging.，Prosperity in the Year of the Dragon。
