completely grind the width of the point. The extension
assembly (128) is normally used during point grinding
operations.

PROFILE GRINDING
For profile grinding of rail, place the grinder on top of
the rail with the rollers (91) resting on top of the rail to
be ground. Adjust each wheel pivot (86) to the position
shown in Figure 3. Grinding is accomplished by moving
the grinder back and forth in line with the rail.

USING THE EXTENSION ASSEMBLY
The extension assembly (128) can be used at anytime
by simply connecting it to one end of the grinder at the
barrel nut (61) and clamping it in place by turning the
adjustable handle (44).
CONNECTING THE HOSES
1. Wipe all hose couplers with a clean lint-free cloth
before making connections.
2. Connect the hoses from the hydraulic power source
OPERATION
to the hose couplers on the grinder. Connect the
return hose first and disconnect it last to minimize
trapped pressure within the grinder motor.
3. Observe flow indicators stamped on hose couplers
to be sure that oil will flow in the proper direction.
The female coupler is the inlet coupler.
Note: The pressure increase in uncoupled hoses
left in the sun may result in making them difficult to
connect. When possible, connect the free ends of
operating hoses together.
OPERATING PROCEDURES
1. Observe all safety precautions.
2. Always start the grinder with the grinding wheel away
from the work surface by turning the handwheel
counter clockwise to raise the grinding wheel.
3. Move the hydraulic circuit control valve to the "ON"
position.
4. Squeeze the trigger momentarily. If the grinder does
not operate, the hoses might be reversed. Verify
correct connection of the hoses before continuing.
5. Start the grinder and move the grinding wheel to the
work surface by turning the handwheel clockwise.
6. Grind a small amount of material at a time adjusting
the grinding wheel as necessary by turning the
handwheel.
Note: If the grinder is not loaded against a work
surface when the trigger is released, the wheel will
take 5-10 seconds to come to a complete stop. Avoid
unintentional contact of the grinding wheel during
the coast down period.
COLD WEATHER OPERATION
If the grinder is to be used during cold weather, preheat
the hydraulic fluid at low engine speed. When using the
normally recommended fluids, fluid temperature should
be at or above 50° F/10° C (400 ssu/82 centistokes)
before use. Damage to the hydraulic system or grinder
can result from use with fluid that is to viscous or too
thick.
