OPERATION

PREOPERATION PROCEDURES

CHECK HYDRAULIC POWER SOURCE

1.Using a calibrated flowmeter and pressure gauge, check that the hydraulic power source develops a flow of 7-10 gpm/26-38 lpm at 1500-2000 psi/105-

140 bar.

2.Make certain the hydraulic power source is equipped with a relief valve set to open at 2100-2250 psi/145- 155 bar minimum.

3.Check that the hydraulic circuit matches the tool for open-center (OC) or closed-center (CC) operation.

CHECK TOOL

1.Make sure all tool accessories are correctly in- stalled. Failure to install tool accessories properly can result in damage to the tool or personal injury.

2.There should be no signs of leaks.

3.The tool should be clean, with all fittings and fasten- ers tight.

CHECK TRIGGER MECHANISM

1.Check that the trigger operates smoothly and is free to travel between the “ON” and “OFF” positions.

CHECK GUARD WELDMENT

1.Inspect the wheel guard weldment for cracks and other structural damage.

INSTALLING AND REMOVING

GRINDING WHEEL

NOTE: Use 6 inch diameter up to 3 inch thick (Type 6 for USA) grinding wheels with a 5/8-11 threaded arbor hole. Only use grinding wheels which comply with ANSI B7.1, B7.5/ISO 525, 603.

USA CONFIGURATION

1.Unscrew the two nuts (98) which secure the guard weldment (95) to the frame and remove the guard weldment.

2.Install the grinding wheel until it comes in contact with the drive flange.

10 ► FG10/PG05 Service Manual

3.Using the wrench (127) provided, place it on the flats of the drive flange. Place a strap wrench on the grinding wheel and then tighten by gripping and turning the strap wrench while holding the wrench provided.

4.Replace the guard weldment.

WHEEL PIVOT ADJUSTMENTS FOR PROFILE OR FROG GRINDING OPERATIONS

NOTE: The PG05 does not contain the pivot wheels or the extension assembly.

GRINDING WINGS

For grinding a wing of the frog, place the grinder on top of the wing with the rollers (91) resting on top of the wing to be ground. Adjust each wheel pivot (86) to the posi- tion shown in figure 1. Grinding is accomplished by mov- ing the grinder back and forth in line with the rail. When finished with one wing, rotate the entire grinder 180 de- grees and place it on the other wing.

IMPORTANT

Never over-tighten the grinding wheel by impacting the wrench with a mallet or hammer. Sufficient torque is attained by hand-tightening the wheel with a strap wrench while securing the drive flange with the wrench provided.
