Setting/Adjustment **

**

Mains Connection
Before connecting the EVA 150 E to the mains, please ensure that the voltage and frequency of the mains supply correspond to the specifications on the machine’s rating plate. Connect the machine to a grounded outlet with a suitable plug. Do not use an adapter plug with this product.
Prior to commissioning make sure that the mains voltage complies with the operating voltage stated on the machine’s rating plate.

Dust Extraction
The EVA 150 E comes with a dust extraction port. Connect a suitable dust extraction system to the port to minimize dust exposure.
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 .
Abrasive Replacement
When replacing the abrasive disk, first disconnect the machine from the mains. Use the provided abrasive replacement tool to remove the old disk and replace with a new one. Ensure that the new disk is properly secured before using the machine again.

Danger
Pull the power plug during all service work.

Attaching abrasives with Velcro® fastening
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.
• Only use original MAFELL abrasives.

Grinding Disk
Only use grinding disks that are compatible with the EVA 150 E. The maximum diameter of the grinding disk should not exceed 150mm. Ensure that the grinding disk is properly secured before using the machine.

Grinding disk selection
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.

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 .
•  Turn the screw 7 back in again.
• Only use original MAFELL grinding disks.

Grinding disk brake
To prevent an unchecked raising of the grinding disk, it is braked by a sleeve 9 . 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.

Additional Handle
The additional handle can be attached to either side of the machine for added stability and control during use. Make sure that it is securely attached before using the machine.
If necessary, the additional handle 10 can be dismantled from the machine with the integrated screw 11 using the enclosed hexagon screw driver.

 Signs and symbols

• This symbol appears at places where you will find instructions for your own safety.
  Non-compliance with these instructions may result in very serious injuries.

• This symbol indicates a potentially hazardous situation. If this situation is not avoided, the product or objects in its vicinity may get damaged.

• This symbol indicates tips for the user and other useful information.

 Operation

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”.

Switching on and off
Short operation

• Switching on: Press switch 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.

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.

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.

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 authorized MAFELL customer service shop for inspection. Regularly remove deposited dust from the machine. In the process, blow out the ventilation openings on the motor.

Storage
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.
