[Start-up and Operation Instructions]

  1. Pre-Start Check: Check the oil level (standard 1.0L), fuel oil level (fuel tank capacity 12L), and ensure that each connection is tight.

  2. Manual Launch: Start the engine according to the operating specifications using the manual pull cord start (no battery).

  3. Weld Adjustment: Quickly adjust the welding current in the range of 50-230A through the high and low current selection switches without stopping or plugging and unplugging.

  4. Auxiliary power usage: Close the DC auxiliary power circuit breaker to power the DC220V power tool. If AC power is required, an AC inverter is available as an option.

  5. Stopping the shear: Turn off the engine and wait until it is completely stopped for inspection and maintenance.

[Maintenance and Precautions]

  • Regularly check the oil level and quality, and replace it in time.

  • Clean the air filter regularly, especially in environments with large wind and sand.

  • Use unleaded gasoline; poor-quality fuel damages the engine.

  • Drain the fuel during long-term storage to prevent the carburetor from clogging.

  • Regularly check key components such as spark plugs, valve clearance, etc. according to the frequency of use.
