1. Lung damage if no suitable protective dust mask is used.
2. Damage to hearing if no suitable ear protection is used.
3. Health damage caused by hand-arm vibrations if the equipment is used over a prolonged period or is not properly guided and maintained.

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.

Fitting the additional handle (Fig. 2)

• The angle grinder must not be used without the additional handle (3).

• The additional handle can be secured in any of 2 positions (A, B).

• The position of the guard (4) can be adjusted to any specific working conditions. Undo the screw
  (a) and turn the cover (4) into the required position.

• Ensure that the guard (4) correctly covers the gear wheel casing.

• Retighten the screw (a).

• Ensure that the guard (4) is secure.

• Take care that the safety device is secure.

WARNING:
Never use the angle grinder without the guard.

TEST RUN FOR NEW GRINDING WHEELS

Allow the right-angle grinder to run in idle for at least 1 minute with the grinding or cutting wheel fitted in place. Vibrating wheels are to be replaced immediately.

Operation

Switch (Fig. 4)

The angle grinder comes with a safety switch which is designed to prevent accidents. To switch on, push the slide switch (a) to the right while at the same time pushing the ON/OFF switch (2) forwards and depressing. To switch off the angle grinder, depress the button (2) at the back. The switch (2) will jump back into its starting position.

WARNING:
Wait until the machine has reached its top speed. You can then position the angle grinder on the workpiece and machine it.

Changing the grinding wheels (Fig. 5)

Use the face spanner (5) supplied to change the grinding wheels. Pull out the power plug.

• Simple wheel change by spindle lock:
• Press the spindle lock and allow the grinding wheel to latch in place.
• Open the flange nut with the face spanner. (Fig. 5)
• Change the grinding or cutting wheel and tighten the flange nut with the face spanner.

Important!
Only ever press the spindle lock when the motor and grinding spindle are at a standstill! You must keep the spindle lock pressed while you change the wheel!

For grinding or cutting wheels up to approx. 3 mm thick, screw on the flange nut with the flat side facing the grinding or cutting wheel.

MOTOR

It is vital for the motor to be well ventilated during operation. Be sure, therefore, to keep the ventilation holes clean at all times.

GRINDING WHEELS

• Never use a grinding or cutting wheel bigger than the specified diameter.
• Before using a grinding or cutting wheel, check its rated speed.
• The wheel s rated speed must be higher than the idle speed of the right-angle grinder.
• Use only grinding and cutting wheels that are approved for a minimum speed of 11000 rpm and a peripheral speed of 80 m/sec.
• Check the direction of rotation when you use diamond cutting wheels. The directional arrow on the diamond cutting wheel must point in the direction in which the tool rotates.

Take special care that the grinding/sanding wheels are properly stored and transported. Ensure that the grinding/sanding wheels are never exposed to shock, jolts or sharp edges (for example during transport or storage in a toolbox). This could cause damage (such as cracks) to the grinding/sanding wheels and place the user in serious danger.

OPERATING MODES

Rough grinding

• Caution: Use the safety device for abrasive cutting (available as accessory, see 9.4)
• When you use the right-angle grinder for cutting purposes, avoid tilting it in the cutting plane. The cutting wheel must have a clean cutting edge.
• A diamond cutting wheel is best used to cut hard stone.
• It is prohibited to use the machine on asbestos materials!
• Never use a cutting wheel for rough grinding.

Replacing the power cable

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.

Cleaning, maintenance and ordering of spare parts

Always pull out the mains power plug before starting any cleaning work.
