1 safe operation of Bobcat excavator -- use of safety strut
The role of the safety brace is to prevent the accidental fall from damaging the maintenance personnel or property after lifting the working arm by restricting the return of the oil cylinder.
If the lifting arm is to be repaired for a long time, it needs to put down the safety lever. By opening the spring 1 and pulling off the pin 2, the safety pole 2 will fall.
The safety pole falls on the oil tank, and the spring is 1 buckled.
Start the machine and lift the working arm. When the oil cylinder is approaching the top, the safety brace brake is stuck to the piston rod of the oil cylinder to complete the limit.
2 after the bobcat excavator finished its maintenance, the steps needed to remove the safety arm were to put down the boom.
The spring is buckled on the spring fixed plate of the working arm. After starting the machine, we want to lift the moving arm slowly. When the oil cylinder reaches a certain length, the safety pole is separated from the cylinder under the effect of spring force.
Do not need to use the safety pole when folded up, with latch 1 lock.
3 Bobcat excavator - internal parts
Open the cab in the front and lower corner of the cab.
The driving room on both sides of the driver's front can turn the cab back to the back, so that the inner parts of the chassis can be overhauled. Because there is a gas spring, the force of the overturn is thirty kilograms enough, and when the cab is upside down about 20 degrees, the cab will play on its own.
If you have to remove the air spring limit after the overhaul, you can put down the cab, when it has just been lifted, it has to press down, and then it will press down after about 20 degrees. It is very convenient for the cab to turn over.
4 safe operation of the cat excavator -- escape method
There is a triangular sign on the rear window of the cab. It is tied up with the glass layering. If the front door fails to go out in case of emergency, you can pull the sign and pull out the glass layering.
After pulling out the glass layering, people can push off the glass and escape from the rear window.
The front door also has such a pull ring. If it doesn't go out, the rear window can not escape. You can pull the ring 1..
After pulling off the ring 1, you can push the glass out of the X wherever you want.
4 rear overhaul of the cat excavator:
Hand in the back door gap, buckle the handle of the inside can open. (some handle to use a large force to pull, if can not open a few rear doors to shake or use things to pry the handle), the other is the rear door locking is not convenient, oil tank locking is also inconvenient.)
The lock tongue can be adjusted in a horizontal direction.
The back door can be opened by moving the limit block at the hinge point to prevent the back door brake from closing. Remember to close the door after overhaul, or it may damage the back door and cause the loss or accident.
5 cat excavator radiator maintenance:
The radiator can be seen after opening the rear cover for routine inspection or maintenance.
Air conditioning intake filter
The intake of air conditioning is divided into two parts, one is the external air intake, the other is the internal air filtration cycle.
The maintenance of the filter element of the engine can be seen by opening the back door. After opening the rear cover of the air filter, the filter element can be seen.
Remove air filter core. General air filter does not need to take out flip cleaning, filter core 60% dirty time is the best quality of air filtration. If often too frequent replacement, it is easy to bring more dust in the cylinder, it is best to wait until the alarm to start cleaning or more.
The skeleton filter core does not usually move it, replace the outside three filter core and replace the internal skeleton filter core. When replacing the filter core, clean the cavity of the air filter with clean wet towel.
The oil filter element should be replaced according to the maintenance manual.
Oil and water separator should pay attention to cleaning up the internal separation, and timely dumping.
The fuel filter element should be replaced according to the maintenance manual, so that the engine fuel pump will not cause abrasion or blockage.
