Assembly

f Before any work on the machine itself, pull the mains

plug.

Bolt the machine to a workbench/bench top with suitable

screws via the 4 holes intended for this.

Mounting the Spark Guard/Workpiece Support

(see figures A

–D)

f Use the machine only with the spark guard 10. Sparks

being expelled can injure your eyes or set objects in the vi-

cinity on fire.

Mount the holder for the spark guard 9 with the two screws.

Screw the spark guard 10 to the holder of the spark guard 9.

Mount the workpiece support 11 as shown in the figure.

f Do not interchange the right and left workpiece sup-

port 11. Otherwise, the clearance between workpiece

support 11 and grinding wheel will be too large. When the

clearance is larger, you are not sufficiently protected

against sparking. The workpiece can be drawn in by the ro-

tational motion of the grinding wheel and lead to injuries.

f Regularly check the clearance between the workpiece

support 11 as well as the holder of the spark guard 9 to

the grinding wheel, and readjust as required. The clear-

ance to the grinding wheel may not exceed 2 mm. When

the clearance is larger, you are not sufficiently protected

against sparking. The workpiece can be drawn in by the ro-

tational motion of the grinding wheel and lead to injuries.

Replace the grinding wheel when the holder of the spark

guard 9 can no longer be adjusted to the required clearance of

2 mm (max.) to the grinding wheel.

Changing a Grinding Wheel

f The rated speed of the accessory must be at least equal

to the maximum speed marked on the power tool. Ac-

cessories running faster than their rated speed can break

and fly apart.

Replace the grinding wheel as soon as its residual material

reaches a thickness of 10 mm.

Loosen the 3 screws of cover 1 and remove cover 1. Hold the

grinder spindle 5 by the spanner flats 12 with the supplied

open-end spanner 13 and unscrew the clamping nut 2.

Note: The grinder spindle 5 on the left side of the machine has

a left-hand thread.

Remove the clamping flange 3 and the grinding wheel from

the grinder spindle 5.

The new grinding wheel is mounted in reverse order. Place the

cover 1 firmly onto the housing and tighten with the 3 screws.

Dress used and out-of-centre grinding wheels with a whet-

stone (accessory) before continuing to use them.

Dust/Chip Extraction

f Dusts from materials such as lead-containing coatings,

some wood types, minerals and metal can be harmful to

one’s health. Touching or breathing-in the dusts can cause

allergic reactions and/or lead to respiratory infections of

the user or bystanders.

Certain dusts, such as oak or beech dust, are considered

as carcinogenic, especially in connection with wood-treat-

ment additives (chromate, wood preservative). Materials

containing asbestos may only be worked by specialists.

– Provide for good ventilation of the working place.

– It is recommended to wear a P2 filter-class respirator.

Observe the relevant regulations in your country for the

materials to be worked.

f Prevent dust accumulation at the workplace. Dusts can

easily ignite.

Operation

Starting Operation

f Observe correct mains voltage! The voltage of the pow-

er source must agree with the voltage specified on the

nameplate of the machine. Power tools marked with

230 V can also be operated with 220 V.

f Check the grinding tools before using. The grinding

tools must be properly mounted and must rotate freely.

Carry out a 1 minute (minimum) test run at maximum

speed in a safe environment with no load. Do not use

damaged, out-of-centre or vibrating grinding tools.

Damaged grinding tools can burst and cause injuries.

Switching On and Off

To start the machine, push the On/Off switch 8 to the “I” po-

sition.

To switch off the machine, push the On/Off switch 8 to the

“0” position.

When not using the power tool, switch it off in order to save

energy.
