Check the cover area for leaks before grinding.

REPLACING THE GRINDING WHEEL

Set the power switch to the OFF position and unplug the grinder from the power source before

beginning this operation.

Drain off all of the grinding fluid through hose #26 (Fig. 1) (as specified in "Maintaining The

Grinding Fluid) and retain it is a suitable container. Remove screws #8 (Fig. 2) inspection cover

frame #9 and plastic inspection cover #7 (Fig. 2) . With one hand, hold the outer diameter of the

grinding wheel and use an allen wrench to loosen the retaining screw #4 (Fig. 2) . Remove screw

#4 (Fig. 2) and retainer #3 (Fig. 2). The grinding wheel #5 (Fig. 2) can then be removed.

A new electrode seal #13 (Fig. 2) should be installed when replacing the Grinding wheel. Follow

the instructions for "REPLACING THE ELECTRODE SEAL."

Install the new grinding wheel, the retainer #3 (Fig. 2) and the screw #4 (Fig. 2). Use only hand

pressure on the outer diameter of the grinding wheel and tighten the screw #4 (Fig. 1).

Replace the inspection cover assembly and refill the grinder to the proper level with the approved

grinding fluid.

REPLACING THE ELECTRODE SEAL

The Neutra LTG uses a foam seal in the wall of the grinding chamber. The seal prevents grinding

fluid from leaking from the grinding chamber, and wipes excess grinding fluid from the tungsten

electrode as it is removed.

With use, the seal will wear and may allow leakage of the grinding fluid. If this occurs, the seal

must be replaced.

To change the seal first remove the vertical console #24 (Fig. 1) on the right side of the grinder.

The seal is located in a recess in the wall of the grinding chamber and must be completely removed.

Thoroughly clean the recess so that the new seal will seat properly.

Coat the outside of the new seal with the waterproof sealer provided. Install the new seal with

the small clip on the inner face in the 6 o'clock (bottom) position. Push the seal firmly into the

recess until the clip engages on the inner wall of the grinding chamber. The vertical console is then

replaced and the bosses on the seal should contact the side of the console.
