Lubrication - Barbco Pathfinder PF500 Operation Manual

LUBERCATION
Use a Barbco Bentonite Pump to mix and pump fluid to reduce torque as needed. Excessive pumping
will sometimes drop the pilot between the machine and the target housing. Causing loss of the top of
the target (sag) as it's displayed on the monitor. Make sure to flush out the rod when the pilots
complete. When piloting downhill it a good idea to use air to push the lubricant out of the rod after
injection, before a tool joint is broken. This will prevent fluid from getting into the sight tube of the pilot
rod,
