Stow SFG10E manual Maintenance/Service

Page 33

5)Remove the worn V-belt. Inspect the electric motor and transmission pulleys for wear and damage. Install the replacement belt, P/N SFB45.

a)Do not install replacement belt if the pulleys have excessively worn grooves. Such pulleys should be replaced to insure proper belt fit. Operating the V- belt in worn pulley grooves will accelerate wear, reduce horsepower and torque levels and significantly reduce component service life.

b)A V-belt should never be forced over a pulley. More belts are broken from this cause than from actual failure in service.

c)Keep the belt as clean and free of foreign material as possible. Do not use belt dressing

6)Rotate the take-up cap screws clockwise until the V- belt has enough tension to not allow it to fall off the pulleys.

REPLACINGTHE LORD®TYPE ELASTOMERIC MOUNTS ONTHE MULTI-ACCESSORY DISC

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 the 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 plate. 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:

1 each, 5/16 allen wrench.

2 each, 5/8 wrenches.

1 each, arbor press of sufficient capacity and stability.

Parts Required:

Elastomeric Mount, P/N SFJ62502 (as required).

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

MAINTENANCE/SERVICE

1)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 disc at waist level

3)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. Appropriate wheel chocks are recommended.

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.

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.

8)Apply the installation lubricant to the exterior surface of the elastomeric mount to minimize damage when pressing into the mounting disc. If the factory supplied lubricant is not available, an acceptable alternative is the use of common liquid soap.
