This combined logging machine offers a variety of optional operation modes. Based on my years of work experience, I will explore the current status and future development trends of these two types of  logging machines, aiming to provide valuable references for the study of logging machines in China. Additionally, for the logging machine Safe Protector, we'll discuss how to maintain the logging machine. 
 Abstract
The combined logging machine provides a diverse range of optional operation modes. Drawing on my years of work experience, I will delve into the current state and future development trends of these two types of  logging machines. The aim  is to offer valuable references for the research on logging machines in China.

Logging Machine Safe Protector Manufacturers: Logging Machine Maintenance Guidelines
1. Running - in Period: The new machine is in the running - in period until the third oil - filling cycle. During use, avoid running the engine at high speed without load to prevent over - burdening the engine during this crucial initial phase. After five to fifteen refuelings, the chainsaw reaches its optimal power output.
2. Daily Pre - work Checks:
    - Conduct a comprehensive visual inspection of the chainsaw. Examine the accelerator, throttle clamp, combination switch, and all other operating components.
    - Test the functionality of the chain brake.
    - Ensure proper chain lubrication.
    - Assess the sharpness of the chain.
    - Check the chain tension.
    - Inspect the guide plate for signs of wear or damage.
    - Verify if the chain moves when the engine is idling.
    - Examine the chain pin of the chain gear.
3. Daily Post - work Checks:
    - Thoroughly clean the entire chainsaw.
    - Clean the entire air - cooling system to maintain efficient heat dissipation.
4. Checks after Each Refueling:
    - Inspect the overall appearance of the chainsaw.
    - Re - evaluate the accelerator, throttle clamp, combination switch, and all operating devices.
    - Re - test the chain brake function.
    - Re - check chain lubrication and tension.
    - Confirm chain movement during engine idling.
5. Weekly Post - work Checks:
    - Clean and rotate the chain guide rail.
    - Remove any burrs on the guide plate.
    - Examine the wear of the sprocket.
    - Check the rubber shock absorber of the electric saw to ensure smooth operation and reduce vibrations.
6. Monthly Post - work Checks:
    - Inspect the filter in the gasoline tank.
    - Clean the gasoline tank to prevent contamination of the fuel.
    - Clean the lubricating oil tank to maintain proper lubrication.
    - Clean the cylinder heat sink to enhance heat dissipation.
7. Air Filter Maintenance:
    - Dust the air filter every 25 hours. If  the working environment is particularly dusty, shorten the maintenance interval.
    - Adjust the damper to the choke position to prevent dust from entering the intake manifold.
    - Wash the foam filter in a clean, non - flammable cleaning solution (such as hot soapy water) and then pat it dry. Replace the felt filter. If the felt filter is not overly dirty, gently tap or blow it clean, but do not wash it. Note that any damaged filter elements must be replaced immediately. During installation, ensure that the marked side of the felt filter is placed inside the filter housing.
8. Spark Plug Maintenance:
    - After every 25 hours of  use, remove the spark plug and use a wire brush to clean the dust on the electrode. It is advisable to adjust the electrode gap to 0.6 - 0.7mm.
9. Engine Performance Troubleshooting:
    - If  the engine experiences issues such as insufficient power, difficult starting, or unstable idling, first check the spark plug. Clean any contaminated spark plugs, check the electrode distance, and adjust as necessary. To prevent spark generation and potential fire hazards, if  the spark plug has a separate joint, firmly screw the nut onto the thread and press the spark - plug cap tightly onto the spark plug.
10. Fuel Filter Maintenance: Clean the fuel filter every 25 hours to ensure the quality of the fuel supply.
11. Muffler Maintenance: Remove the muffler every 50 hours, clean the exhaust port and muffler outlet, and remove any carbon deposits in the upper area to maintain proper exhaust flow.
