• Lead from lead-based paints,

• Crystalline silica from bricks and cement and other masonry products, and

• Arsenic and chromium from chemicallytreated lumber.

Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment,

INSTALLING SANDING SHEETS

Your sander uses hook-and

To change, merely peel off the old sandpaper, remove dust from the backing pad if necessary, and press the new sandpaper in place. Be sure to align the sanding sheet holes with the holes in the backing pad to allow the dust extraction system to function (Fig. 4).

After considerable use the backing pad surface will become worn, and the backing pad must be replaced when it no longer offers a firm grip. If you are experiencing premature wear of the backing pad facing, decrease the amount of pressure you are applying during operation of the tool.

Tool Tips

This tool is particularly suitable for one handed operation, and access to corners and edges that are otherwise difficult to reach and require hand sanding. Profiles and grooves may be finished using the tip or edge of the selected attachment, which should occasionally be rotated during use to distribute the wear on the attachment and backing pad surface.

Always be certain that smaller workpieces are securely fastened to a bench or other support. Larger panels may be held in place by hand on a bench or sawhorses.

SANDING: Open-coat aluminum oxide sanding sheets are recommended for most wood or metal sanding applications, as this synthetic material cuts quickly and wears well. Some applications, such as metal finishing or cleaning, require special abrasive pads which are available from your dealer. For best results, use sanding and polishing accessories which are of superior quality and are carefully selected to produce professional quality results with your sander.

The following suggestions may be used as a general guide for abrasive selection, but the best results will be obtained by sanding a test sample of the workpiece first.

Grit

Coarse For rough wood or metal sanding,

Medium For general wood or metal sanding

Fine For final finishing of wood, metal,

Extra fine For final sanding of bare wood,

With the workpiece firmly secured, turn tool on as described above. Contact the work with the tool after the sander has reached its full speed, and remove it from the work before switching the tool off. Operating your sander in this manner will prolong switch and motor life, and greatly increase the quality of your work.

Application

and rust or old finish removal.

plaster and other surfaces.

smoothing old paint, or preparing a finished surface for recoating.

Move the sander in long steady strokes parallel to the grain using some lateral motion to overlap the strokes by as much as 75%. DO NOT apply excessive pressure — let the tool do the work. Excessive pressure will result in poor handling, vibration, and unwanted sanding marks (Fig. 12).

FIG. 12

If the surface is rough, begin with coarser grits and then complete the surfacing with medium and fine abrasives. To avoid uneven results, do not skip more than one grit size when going from coarser to finer, and do not sand in one area for too long. When the job is completed, gently lift the tool from the work surface and slide switch to the "OFF" position.

POLISHING: Your Multi-finishing sander may be fitted with optional abrasive mesh or polishing pads to polish or remove scratches or corrosion from metal, painted, or other surfaces. The tool is operated in much the same way as when sanding, but the following points should be observed;

Use light pressure and a circular or overlapping motion to remove scratches and corrosion or polish a surface. If using a compound, use only as much as necessary and do not use the dust extraction feature.

When working in very confined areas or louvered panels, the pad extension plate should be used.

Clean the buffing or mesh pads with mild deter gents and warm water. DO NOT use solvents.
