The vibration value changes according to the area of application of the electric equipment and may exceed the specified value in exceptional circumstances.

Keep the noise emissions and vibrations to a minimum.

• Only use appliances which are in perfect working order.
  • Service and clean the appliance regularly.
  • Adapt your working style to suit the appliance.
  • Do not overload the appliance.
• Have the appliance serviced whenever necessary.
• Switch the appliance off when it is not in use.
  • Wear protective gloves.

5. Before starting the equipment

Before you connect the equipment to the mains supply make sure that the data on the rating plate are identical to the mains data.

Warning!

Always pull the power plug before making adjustments to the equipment.

• The machine must be set up so that it stands firmly, i.e. it must be securely screwed to a work bench or similar.
• All covers and safety devices have to be properly fitted before the equipment is switched on.
• It must be possible for the grinding wheel to run freely.

5.1 Assembling the spark defl ector (Fig. 1/3/4/5)

• Fit the spark deflector (3) to the safety hood (4) using the screws (10), as shown in Fig. 4.
- Adjust the spark deflector (3) using the screw (10) so that the distance between the dry grinding wheel (5) and the spark deflector (3) is as small as possible and certainly does not exceed 2 mm.
- Adjust the spark deflector (3) periodically to compensate for wear on the wheel.

GB

5.2 Assembling the workpiece support (Fig. 2/6)

Fit the workpiece support (7) to the workpiece support holder (15) using the workpiece support fastening screw (6), washer (12), lock washer (13) and workpiece support locking knob (14), as shown in Fig. 6.

5.3 Adjusting the workpiece supports (Fig. 6 / Item 7)

• Adjust the workpiece support (7) using the locking button (14) so that the distance between the dry grinding wheel (5) and the workpiece support (7) is as small as possible and certainly does not exceed 2 mm.
• Adjust the workpiece supports (7) periodically to compensate for wear on the dry grinding wheel.

6. Operation

6.1 On/Off switch (1)

To switch on the equipment set the On/Off switch (1) to position 1.

Move the On/Off switch (1) to position 0 to switch off the equipment.

After switching on, wait for the equipment to reach its maximum speed of rotation. Only then should you begin with the grinding.

6.2 Dry grinding

• Place the workpiece onto the workpiece support (7) and slowly guide the workpiece towards the grinding wheel (5) at the desired angle to the point where workpiece and grinding wheel make contact.
• Move the workpiece slightly back and forth to produce an optimal grinding result. This way the grinding wheel (5) will be evenly worn. Allow the workpiece to cool down occasionally.

6.3 Wet grinding

Before beginning with the wet grinding, check that there is enough water in the water container (9) (a third of the wet grinding wheel must be standing in water!). Switch on the grinder with the On/Off switch (1) and stand in front of the wet grinding wheel. Grip the workpiece with both hands and lower it carefully onto the wet grinding wheel.

You can also rest the workpiece on the teeth on the water container and lower it onto the grinding wheel.

6.4 Changing the grinding wheel

If the grinding wheel for this equipment becomes damaged or worn, it must be replaced by the manufacturer or its after-sales service or similarly trained personnel in order to avoid danger.

7. Replacing the power cable

Danger!

If the power cable for this equipment is damaged, it must be replaced by the manufacturer or its after-sales service or similarly trained personnel to avoid danger.
