Step Description Images

1

Remove the antifouling mesh assembly

2

Clean the buffer tube assembly

  1. Insert the needle into the buffer tube assembly, all the way

  2. Draw out the plunger of the syringe past the 10ml point

  3. Install the syringe kickstand so that it cups the plunger and supports it in the drawn-out position; the syringe will brace against the flange on the plunger and the barrel

The syringe will draw up oil and any particles until the assembly is empty, and then, it will draw air.
