BRUSH CUTTER, HYDRAULIC HOSE CLEANUP FITTING WITH PROCEDURE DOCUMENT

If a motor has failed on a standard flow brush cutter, there is a slight chance of a small amount of debris in the hose lines.  Connecting the hoses together and running the hydraulic system on the machine for 2 minutes will take any floating debris to the machine's filter.  There isn't normally enough debris in the lines to even merit a filter change.  This is simply for peace of mind for anyone who is concerned.
