✓【NOTE】1. Before the first use, it is necessary to complete the running in cycle, which must be done 3-5 times, otherwise the clutch will slip and overheat. 2. Lubrication: Apply lubricating oil only to the retaining ring before use. The holes on the drum are for heat dissipation and are used to dissipate heat. Do not inject oil into the holes!!! Otherwise, it will cause permanent slippage and pose a safety hazard (the machine cannot be stopped after starting)

✓【Installation suggestions】Before use, lubricate the retaining ring by applying oil until it seeps in, then rotate the clutch to ensure smooth operation—no disassembly needed if it moves freely. After installation, a run-in of 3 to 5 cycles is required for the clutch shoes to develop full friction. Perform each cycle as follows: start the engine with no load until the clutch engages, hold for 10 seconds, then turn off and let cool.Repeat this cycle 3-5 times, gradually increasing load,speed from 0 to maximum, with a 2-minute interval for cooling each time.Once completed without issues, normal operation can begin
