Sound power level Workplace-related emission value

The measuring inaccuracy K is 3 dB. The values stated do not take into consideration any possible series variances and are not suitable for determining the rating levels, as these fluctuate in dependence on the time in service, the respective type of machining and the environmental influences. The noise rating level can therefore only be determined on an individual basis at the machine user's position.

2.5 Vibration specifications

Noise emission values determined according to EN 60745-2-4 : at the main handle smaller than 2.5 m/s

at the front handle 3.6 m/s

The measuring inaccuracy K is 1.5 m/s

2.7 Use according to intended purpose

The orbital disk sander is exclusively intended for the dry smooth surface finishing of wood, paints, lacquers, filler, plaster and metal. Any other use than described above is not permissible. The manufacturer cannot be held liable for any damage arising from such other use. So as to use the machine as intended, comply with the operating, maintenance and repair instructions specified by Mafell.

Danger Even if used in accordance with its intended purpose and despite conforming with the safety instructions, residual risks caused by the intended use will always remain.

- Touching the abrasive grid or the grinding disk during grinding. - Touching live parts with the housing open and the mains plug not removed. - Hearing can be impaired when working for long periods without ear protectors. - - Emission of harmful wood dusts when working for long periods without extraction. 3 Safety instructions

Danger Always observe the following safety instructions and the safety regulations applicable in the respective country of use!

General instructions: - Children and adolescents must not operate this machine. This rule does not apply to young persons receiving training and being supervised by an expert. - Never work without the protection devices prescribed for the respective operating sequence and do not make any changes to the machine that could impair safety. - When operating the machine outdoors, use of an earth-leakage circuit-breaker is recommended. - Damaged cables or plugs must be immediately replaced. - Avoid sharp bends in the cable. Especially when transporting and storing the machine, do not wind the cable around the machine. Instructions on the use of personal protective equipment: - Always wear ear protectors during work. - Dust arising during work is often hazardous (e.g. when processing oak and beech wood, mineral materials, metal or coats of paint containing lead or other harmful substances) and should not enter the body. Do not touch or inhale the dust. Use a dust extraction and in addition wear a dust protection mask. Remove any deposited dust thoroughly, e.g. by vacuuming it with a special vacuum cleaner. Please also observe these instructions when changing the filter bag Instructions on operation: - Do not reach with your hands into the oscillation range of the abrasive grid or its mounting. With your other hand, support the supplementary handle or the motor casing. - Never support the workpiece in your hand or over your leg. Secure the workpiece against a sturdy support. - Whenever possible, secure the workpiece against slipping, e.g. with screw clamps. - Provide for an unobstructed and slip-proof location with adequate lighting. - Only use abrasive grids with the dimensions specified in these operating instructions. Instructions on service and maintenance: - Regularly cleaning the machine, especially the adjusting devices and guides, constitutes an important safety factor. - Only original MAFELL spare parts and accessories may be used. Otherwise the manufacturer will not accept any warranty claims and cannot be held liable.

Only connect the machine with the mains when it is switched off.-16- 4 Setting / Adjustment

4.1 Mains connection

Prior to commissioning make sure that the mains voltage complies with the operating voltage stated on the machine's rating plate.

Connect the machine to a suitable external dust extractor during all work generating a considerable amount of dust. The air velocity must be at least 20 m/s (65.6 ft / sec.). The internal diameter of hose connector is 35 mm ( 1 3/8 in.). Correct dust extraction can only be guaranteed if an abrasive grid or punched sanding paper is used. As the sander is equipped with its own dust extraction, it is possible to work with the sander's own dust extraction and the filter bag supplied for short assignments and in inaccessible areas. Make sure that the filter bag is replaced on a regular basis (Fig. 7 and 8).

4.3 Abrasive replacement

Danger Pull the power plug during all service work.

Attaching abrasives with Velcro® fastening (Fig. 2) The Velcro® fastening allows for a quick changing of the abrasive 6 Free the grinding disk 4 of dust and dirt before fitting a new abrasive. When using abrasive grids, the protective layer 5 should be fitted to the grinding disk to prevent excessive wear. When pressing the protective layer into place, pay attention that the punched holes match those of the sanding pad.

In order to achieve a good grinding quality, use the correct grinding disk in accordance with the applications in the following list: Universal for rough and fine grinding on surfaces, grinding at edges: - Grinding disk "hard" ø150, 35 Shore Fine grinding of mouldings, curvatures and radii. Do not use on edges - - Grinding disk "soft" ø150, 20 Shore Order No. see special accessories.

4.4.2 Grinding disk exchange

Danger Pull the power plug during all service work.

Proceed as follows: Take out the screw 7 (Fig. 3). Now the grinding disk 4 can be replaced. Turn the grinding disk while fitting it until it engages on the flats of the locating bolt 8 (Fig. 4). Turn the screw 7 (Fig. 3) back in again.

To prevent an unchecked raising of the grinding disk, it is braked by a sleeve 9 (Fig. 5). As the sleeve wears out in the course of time, it must be replaced with a new one at a MAFELL customer service shop if the braking effect decreases.

4.5 Additional handle

If necessary, the additional handle 10 (Fig. 6) can be dismantled from the machine with the integrated screw 11 using the enclosed hexagon screw driver.

The edge protection 12 (Fig. 6) can be detached from the machine, if necessary. To do so, turn it to the left-17- into its rear position, then push downwards and pull out to the rear. 5 Operation

5.1 Initial operation

Personnel entrusted to work with the machine must be made aware of the operating instructions, calling particular attention to the chapter "Safety instructions".

5.2 Switching on and off

Short operation Switching on: Press switch 1 (Fig.1). Switching off: Release the switch. Continuous operation Switching on: Press switch 1 and locking button 2 consecutively. Then release the switch with depressed locking button. The motor runs without pressure on the switch. Switching off: Press switch 1 until locking button 2 pops out. Then release the switch.

5.3 Control electronics

The stroke rate of the orbital disk sander EVA150E 3 / EVA150E 5 can be adjusted in a continuously variable manner between 9000 strokes/min and 22000 strokes/min at the adjusting wheel 3 (Fig.1) of the control electronics . With the control electronics, the sanding speed can be adapted to the respective material. Thus, heat- sensitive materials such as plastics, paints, varnishes and glazes are protected against damage by excessive sanding speeds. In addition, the abrasive grid lasts longer as it does not get clogged. Thus, when grinding different materials, always use the control electronics to select a grinding speed that is appropriate for the material to be processed.

5.4 Work instructions

The best sanding performance is achieved with slight pressure. You can avoid scratching caused by switching on and off, if you position the running orbital sander on the workpiece and also remove it with running motor from the workpiece. 6 Service and maintenance

Danger Pull the power plug during all service work.

MAFELL machines are designed to be low in maintenance. The ball bearings used are greased for life. When the machine has been in operation for a longer period of time, we recommend to hand the machine in at an authorised MAFELL customer service shop for inspection. Regularly remove deposited dust from the machine. In the process, blow out the ventilation openings on the motor.

If the machine is not used for a longer period of time, it has to be carefully cleaned. Spray bright metal parts with a rust inhibitor.-18- 7 Troubleshooting

Danger Determining the causes for existing defects and eliminating these always requires increased attention and caution. Pull the mains plug beforehand!

Some of the most frequent defects and their causes are listed in the following chart. In case of other defects, contact your dealer or the MAFELL customer service.
