MAINTENANCE/SERVICE

REPLACING THE LORD® TYPE ELASTOMERIC MOUNTS ON THE MULTI-ACCESSORY DISCS. Application: All Models.

Lord® type elastomeric rubber mounts are utilized to allow each multi-accessory disc to maintain full contact with the work surface. The rubber mounts afford a constant flex rate for each multi-accessory disc throughout its service life. The rubber compound is resistive to the effects of ultraviolet radiation and most common chemicals encountered when operating the SURFACE GRINDER .

During the manufacturing process, the rubber mounts are pressed into specially machined cavities in the disc mounting plates. Under normal usage and job applications, the Lord® type rubber mounts will deliver appropriate performance for the expected service life of the SURFACE GRINDER. However, an attachment mounted in the multi-accessory disc that directly strikes a vertical floor obstruction with sufficient impact force can cause one or more of the mounts to become separated from the mounting plate. This occurrence will not allow the multi- accessory disc to maintain full contact with the work surface. This occurrence is also intended to protect the transmission gears and bearings from costly damage and the operator from an impact force that could cause personal injury.

Tools Required:

1each, 5/16 allen wrench.

2each, 5/8 wrenches.

1each, arbor press of sufficient capacity and stability.

Parts Required:

Elastomeric Mount, P/N 29018-055 (as required).

1container each: Installation Lubricant (or approved equivalent).

1)If the SURFACE GRINDER is powered by an engine, disconnect the spark plug wire. If powered by an electric motor, disconnect the extension cord or SURFACE GRINDER from the power source.

2)Position the SURFACE GRINDER on a suitable work bench with the multi-accessory discs at waist level

3)Remove the rubber latches and slide the belt guard away from the engine/electric motor until it clears the catch mechanism. Remove the belt guard from the main frame. Clean the inside of the belt guard with an appropriate safety solvent. Check for signs of wear and damage. Secure in a proper storage area.

CAUTION

Observe all applicable safety precautions for the solvent.

4)Tilt the SURFACE GRINDER back until the operator handle comes in contact with the surface. The SURFACE GRINDER may not be in a stable position in this configuration. To minimize the possibility of property damage and/or personal injury, apply an appropriate weight to the handle to stabilize the SURFACE GRINDER. FIGURE 48. Other means can also be utilized to support the frame and provide proper machine stability. Appropriate wheel chocks are recommended. Follow the instructions for this procedure as outline in

INSTALLING A MULTI-ACCESSORY ATTACHMENT (not including multi-segmented,

dry diamond blades) IN THE COUNTERROTATING DISCS.

5)Utilizing the Allen wrench, remove the affected aluminum multi-accessory disc (if still attached) from the SURFACE GRINDER.

6)Utilizing the 9/16-inch wrenches, remove the cap screws that retain the Lord® rubber mounts to both the mounting plate and transmission shaft.

FIGURE 48

7)Inspect the appropriate cavities in the mounting plate for wear and damage. Any nick or burr must be removed by the use of an appropriate file, followed by the use of 240 grit sandpaper. FIGURE 49.
