Electrical Safety

Double Insulated tools are equipped with a polarized plug (one blade is wider than the other.) This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install a polarized outlet. Do not change the plug in any way. Double

WARNING

grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• Lead from lead-based paints,

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

Some dust created by power sanding, sawing,

• 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, such as those dust masks that are specially designed to filter out microscopic particles.

WARNING

ATTACHING REGULAR ABRASIVE

SHEETS USING SHEETLOC™ SYSTEM

The Bosch-exclusive SheetLoc™ Sandpaper Attachment System pulls regular abrasive sheets (sandpaper) flat and tight before clamping to prevent wrinkles, creases and tears for optimal sanding performance and longer paper life. Patent Pending.

1.While pressing the front clamp release button, insert the abrasive sheet (grit side down) between the front clamp and base plate. Make sure sheet is centered under the front clamp and inserted deep enough to be fully under the front clamp, then release button (Fig. 2). Note: It is not necessary to insert the paper so deep that its front edge curls and goes behind the back of the front clamp.

2.Press the rear clamp lever inward to unlock from latch and move lever away from base plate. (Fig. 3).

3. Wrap the abrasive sheet around the length of the pad and slide free end of sheet between rear clamp bar and rear clamp spring plate (Fig. 4). Flatten the abrasive sheet by pushing it as far to the back as possible, then move the rear clamp lever to the base plate and lock in place (Fig. 5). This action pulls the abrasive sheet taut while clamping, which prevents wrinkles, creases and tears.

Simply press the front clamp button and release the rear clamp lever to remove the abrasive sheet.

Always disconnect the plug from the power source

ATTACHING PSA “STICK-ON”

ABRASIVE SHEETS

Your sander can also be used with PSAbacked “stick-on” abrasive sheets (sandpaper), which have pressure sensitive adhesive.

1. Peel protective sheet from the back of PSA sheet.

2. Align PSA sheet with backing pad and press firmly in place.

Notes:

• Make sure that SheetLoc™ System’s rear clamp lever is latched, even when PSA abrasive sheets are used.

• Remove PSA sheets soon after completing each sanding operation in order to prevent the adhesive from creating a hardened bond with the backing pad.

Dust Collection

MICROFILTER DUST CANISTER —The

integral dust extraction system collects sanding dust in canister supplied with your sander. For maximum efficiency, the dust canister should be emptied frequently during operation.

WARNING

frequently, after completion of sanding and before storing the sander. Be

extremely careful of dust disposal, materials in fine particle form may be explosive. Do not throw sanding dust on an open fire. Combustion from mixture of varnishes, lacquers, polyurethane, oil or water with dust particles can occur if there is a static discharge, spark introduced in the box, or excessive heat.

REMOVING AND INSTALLING

To remove dust canister: squeeze release

tabs on both sides of canister and simply pull away from the tool (Fig. 1).

To install dust canister: align dust port with hole in canister and push canister onto tool until it locks into place.

REMOVING PSA ABRASIVE SHEETS

To remove, lift an edge of accessory with your fingernail and peel it off the backing pad.

Note: If PSA paper is accidentally left on the pad, the best way to remove it is to sand for a few minutes to soften the adhesive backing.

PUNCH PLATE

After the paper has been installed, it will be necessary to punch holes into the paper using the punch plate provided with your sander. Align sander base with punch plate and push down on sander until punch plate pierces the paper. Then remove punch plate from sander (Fig. 1).

FIG. 6

CLEANING AND EMPTYING THE

DUST CANISTER

To empty canister, hold canister as shown and maintain a firm grip (Fig. 6). Firmly push upward on tab on corner of lid, and remove from canister. Knock excess dust out of the microfilter, or remove dust with your fingers or a soft brush. You may notice that all the dust may not come out of the canister. This will not affect sanding performance but will reduce dust collection efficiency.

NOTE: Do not wash the micro filter with soap and water. Dust may become more firmly lodged in the pores, which will reduce dust collection, and damage the micro filter.

ATTACHING VACUUM HOSE

When the canister is removed from the tool, an (optional) vacuum hose accessory can be attached to the dust port. To use this feature, attach vacuum adapter(s) and vacuum hose (optional accessories) to dust port, then connect opposite end of the vacuum hose to a shop vacuum cleaner (Fig. 7).

Operating Instructions

ROCKER “ON/OFF” SWITCH

TO TURN THE TOOL “ON” or “OFF”: Push IN the switch rocker to the left or right side of the tool. Always hold the sander off the work when turning the switch “ON” or “OFF”.

ABRASIVE SHEETS (SANDPAPER)

Aluminum oxide, silicon carbide, or other synthetic abrasives are recommended for power sanding use. Natural abrasives, such as flint or garnet sheet are too soft for economical use in power sanding. For best results, use Bosch abrasive sheets: The uniform spacing between grains minimizes filling or loading. The high quality aluminum oxide sheet with heavy backing cuts faster and lasts longer.

The following are recommended abrasive sheets and applications:

Coarse Grit: For rough wood sanding.

Medium Grit: For general wood sanding.

Fine Grit: For smoothing wood or

plaster patches.

Extra Fine Grit: For final sanding bare

wood and smoothing old paint.

There are also different types of paper made for wood, paint and other surfaces.

FIG. 7

Abrasive sheets can be purchased pre-sized or can be conveniently cut from large-size commercially available sheets (standard size: 9" x 11-1/16" or 228 x 280mm). Cut into four pieces of equal size as shown (Fig. 8). Choose the proper grit for the job.

SANDING TIPS

Bosch orbital sanders are designed to produce exceptional finishes on wood surfaces, speed stock removal, or to remove lacquer, varnish, and other coated finishes.

Orbital sanding provides fast, smooth final finishes. And this model can sand flush on all three sides of the tool to get in tight places typical of cabinets, desks and shelving.

• Starting and stopping of sanding - Contact the work with the tool after sander has reached its full speed and remove it from the work before turning the switch “OFF”. Operating in this manner will prolong switch and motor life and will greatly increase the quality of your work.

• This sander’s even weight distribution and the prevention of paper slippage by the SheetLoc system virtually eliminate any benefit from pressing on the sander. Excessive pressure to the sander may result in an uneven sanding job and premature grit wear. Constant and excessive pressure can cause overheating and possible damage to the motor, as well as premature wear out of the pad.

• It's usually best to work in strokes that parallel the grain, using some lateral motion so the main strokes are overlapped as much as 75%.

• If the surface is rough, start sanding with a coarse grit, then medium, and then finish with a fine or extra-fine grit. This procedure will vary with different types of materials and work.

• Continue to sand with each grit until the surface looks uniform.

• When going from one grit size to a finer size, do not skip more than two grit sizes.

• To remove the greatest amount of stock, use a coarse grit and move the sander steadily over the entire surface against the grain as well as with the grain. DO NOT REMAIN IN ONE SPOT TOO LONG. It may remove too much material and uneven sanding will result.

• Sanding with the grain of the wood gives the smoothest final finish.

STORING THE SANDER

• Always latch the rear clamp lever when the tool is not in use.

• Do not store tool with PSA sheets on pad, as sanding creates heat, which will cause an adhesive bond between the paper and the pad to harden when paper and pad cool down. (See REMOVING PSA ABRASIVE SHEETS on page 8.)
