3)  If  the  connector  plug  doesn't  fit  or  if  it  is  defective,  only 

qualified electricians may modify or replace it.

4)  The grounding wire should be connected to green-yellow.
5)  A damaged cable must be replaced immediately.
6)  After connecting, check the correct running direction.
7)  Make  sure  that  a  possible  extension  cord  is  in  good 

condition  and  suitable  for  the  transmission  of  power.  An 
undersized  cord  reduces  the  transmission  of  power  and 

heats up.

8)  A damaged cable must be replaced immediately.

Operation

See image 6

1. 

On/Off

• 

To turn the machine ON, press "I" (green).

• 

To turn the machine OFF, press "O" (red).

2.  Table
• 

To  tilt  the  worktable  loosen  the  quick  release,  bring  the 
work  table  to  the  desired  position  and  tighten  the  quick 

release again.

• 

Use a protractor to set it at exactly 90°.

3.  Mitre gauge
• 

The metre gauge is provided for use on the grinding table.

• 

The metre gauge can be used for angles of up to 45°, to the 
left or right, by releasing the locking button and adjusting 

the metre gauge to the desired angle. The button must be 
tightened again.

4. 

Dust collection connection

• 

The machine is equipped with a dust collector plug with a 
diameter of 35 mm.

• 

Always use a suitable dust collector (e.g., vacuum cleaner)!

Maintenance and cleaning

6

Attention: Don't clean or do maintenance on the 

machine while it is still connected to the power supply. The 
machine may be damaged and injuries might occur due to 
the unintended switching on of the machine! Therefore, 
switch the machine OFF and disconnect it from the power 
supply before any maintenance works or cleaning is carried 
out.

The  machine  does  not  require  extensive  maintenance.  If 
malfunctions and defects occur, contact a qualified technician 
only.  Before  the  first  operation  as  well  as  after  every  100 
operation  hours,  you  must  lubricate  all  connecting  parts  (if 
required, remove all debris and dust with a brush beforehand). 
Check  the  condition  of  the  security  labels  regularly.  Replace 
them  if  required.  Check  the  condition  of  the  Sanding  Disc 
regularly. Store the machine in a locked, dry location.

Troubleshooting

Before you start checking for defects by elimination disconnect the machine from power supply.

Problem

Possible cause

Solution

The machine stops or 

will not start.

ON/OFF switch is damaged.

• 

Grinder unplugged - Overload tripped.

• 

Fuse has blown or circuit breaker tripped.

• 

Cord damaged.

• 

Check the switch.

• 

Check all power connections.

• 

Allow motor to cool down and reset by pushing 
OFF switch.

• 

Change fuse or reset the circuit breaker.

•  Change cable.

The machine slows 

down while working.

• 

Exerting too much pressure on the sanding 

disc.

• 

Exert  less  pressure  on  the  work-piece/sanding 

disc.

Bad grinding results.

• 

Abrasive too coarse.

•  Grained.

• 

Use a less coarse abrasive.

Rapid wear of the 

abrasive.

• 

Abrasive too fine.

•  Grained.

• 

Use a more coarse abrasive.

Grinding angle is 

wrong.

• 

Adjusted angle is wrong.

•  Readjust the angle.

of round.

• 

Sanding disc is not centrally mounted.

• 

Mount the sanding disc centrally.
