Bar Oil Pump Adjustments

The DH0144 bar oil pump (Fig. 9) is a single acting pump that can pump up to 32 cc or 1.08 oz. of bar oil per

cycle, enough for about 30 seconds of cutting. There is a hose connected to the feed and motor control valve

manifold (Fig. 8, item 6) that connects to the fitting (Fig.9, hydraulic pressure in) on the bar oil pump. When a cut

is started flow and pressure from the manifold pushes on the pumping rod and piston to force a metered amount of

oil to the bar. The metering valve in Figure 8 is sensitive to volume adjustment. Turning it clockwise reduces the

speed oil is pumped and turning it counterclockwise increases the speed the oil comes out. If you run the tank out

of oil you may need to prime the pump. To prime the pump remove the barrel nut and pull the pumping chamber,

pumping piston and pumping rod. Fill the barrel with bar oil up to the vent hole. Reinstall the pumping rod

assembly into the pumping chamber with care to not damage the rod seal. Reinstall the pumping chamber and

pumping rod assembly into the barrel with care to not damage the piston or the o-ring and retighten the barrel nut.

To reduce the chance of seal damage make sure the seals are oiled and wiggle in a circular motion as you push the

parts together.
