WARNING: We recommend the use of a residual current

device with a residual current rating of 30mA orless. In spite of the application of the relevant safety regulations and the implementation of safety devices, certain residual risks cannot be avoided. These are:

• Impairment ofhearing.

• Risk of personal injury due to flyingparticles.

• Risk of burns due to accessories becoming hot duringoperation.

• Risk of personal injury due to prolongeduse.

SAVE THESE INSTRUCTIONS

WARNING: Observe the applicable regulations for

sanding paint. Pay special attention to the following:

• Whenever possible, use a vacuum extractor for dustcollection.

• Take special care when sanding paint which is possibly leadbased: ‑ Do not let children or pregnant women enter the work area. All persons entering the work area should wear a mask specially designed for protection against lead paint dust and fumes. Do not eat, drink or smoke in the workarea.

• Dispose of dust particles and any other removal debrissafely. Additional Specific Safety Rules for Sanders

WARNING: Contact with or inhalation of dusts arising

from sanding applications may endanger the health of the operator and possible bystanders. Wear a dust mask specifically designed for protection against toxic dust and fumes and ensure that persons within or entering the work area are alsoprotected. Do not operate the unit without a dust collectionsystem.

WARNING: Use this tool in a well-ventilated area when

sanding ferrous metals. Do not operate the tool near flammable liquids, gases or dust. Sparks or hot particles from sanding or arcing motor brushes may ignite combustiblematerials.

WARNING: Do not use the dust filter cassette or the dust

extraction adaptor to storeobjects. Additional Safety Instructions for Sanding Operations a ) Do not use excessively oversized sanding disc paper. Follow manufacturer’s recommendations, when selecting sanding paper. Larger sanding paper extending beyond the sanding pad presents a laceration hazard and may cause snagging, tearing of the disc orkickback.

FURTHER SAFETY INSTRUCTIONS FOR ALL

OPERATIONS Kickback and Related Warnings Kickback is a sudden reaction to a pinched or snagged rotating wheel, backing pad, brush or any other accessory. Pinching or snagging causes rapid stalling of the rotating accessory which in turn causes the uncontrolled power tool to be forced in the direction opposite of the accessory’s rotation at the point of thebinding. For example, if an abrasive wheel is snagged or pinched by the workpiece, the edge of the wheel that is entering into the pinch point can dig into the surface of the material causing the wheel to climb out or kick out. The wheel may either jump toward or away from the operator, depending on direction of the wheel’s movement at the point of pinching. Abrasive wheels may also break under theseconditions. Kickback is the result of tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below: a ) Maintain a firm grip on the power tool and position your body and arm to allow you to resist kickback forces. Always use auxiliary handle, if provided, for maximum control over kickback or torque reaction during start up. The operator can control torque reaction or kickback forces, if proper precautions aretaken. b ) Never place your hand near the rotating accessory. Accessory may kickback over yourhand. c ) Do not position your body in the area where power tool will move if kickback occurs. Kickback will propel the tool in direction opposite to the wheel’s movement at the point ofsnagging. d ) Use special care when working corners, sharp edges etc. Avoid bouncing and snagging the accessory. Corners, sharp edges or bouncing have a tendency to snag the rotating accessory and cause loss of control orkickback. e ) Do not attach a saw chain woodcarving blade or toothed saw blade. Such blades create frequent kickback and loss ofcontrol. l ) Do not run the power tool while carrying it at your side. Accidental contact with the spinning accessory could snag your clothing, pulling the accessory into yourbody. m ) Regularly clean the power tool’s air vents. The motor’s fan will draw the dust inside the housing and excessive accumulation of powdered metal may cause electricalhazards. n ) Do not operate the power tool near flammable materials. Sparks could ignite thesematerials. o ) Do not use accessories that require liquid coolants. Using water or other liquid coolants may result in electrocution orshock.22 ENGLISH Slider Switch (Fig. C)

CAUTION: Hold the side handle and body of the tool firmly to maintain control of the tool at start up and during use and until the wheel or accessory stops rotating.

The greatest danger of lead poisoning is to children and pregnantwomen. Sanding Drywall (Fig. E)

WARNING: To reduce the risk of personal injury, ALWAYS

wear a respirator approved for “Dust andMist” and connect the drywall sander to a suitable dustextractor. The drywall sander has an articulating sanding head. The head can swivel in multiple directions, allowing the abrasive pad to conform to the work surface. This action enables you to sand the top, middle, and bottom of a wall or ceiling joint without changingposition.

1. Turn the vacuum cleaner switch ON (I).

2. Turn drywall sander switchON.

3. Position the drywall sander lightly against the work surface.

Apply just enough pressure to align the sanding head with the worksurface.

4. Apply additional pressure to engage the abrasive pad on the

work surface. Move the sander in an overlapping pattern to smooth the drywall compound down to a“featheredge”.

5. Apply ONLY enough pressure to keep the abrasive pad flat

6. Keep the sander in constant motion while the abrasive pad is in

contact with the work surface. Use a steady, sweeping motion. Excessive pressure, stopping the sander on the work, or moving the sander erratically can cause unacceptable swirl marks and unevenness in the worksurface. nOTE: Do not allow rotating abrasive pad to contact sharp protrusions. Contact with protruding objects (nails, screws, electrical boxes, etc.) can severely damage the abrasivepad. Proper hand position requires one hand on the main handle

and one hand on the main tube
