correct fitting of the protective device

Ensure that the protective cover (6) is fitted cor

-

rectly and that the fixing screws have been tight

-

ened!  Before  tightening  the  fixing  screws,  turn 
the on and off switch (1) to the (0) position and 
remove the mains plug!

Grinding and surface processing

In order to grind surfaces you should use a coarse 
abrasive disk with a sunken centre. You can use 
abrasive disks with diameter of 115mm. The maxi

-

mum thickness is 6 mm.

cutting metal

In  order  to  cut  rods,  tubes  and  metal  parts  you 
should  use  a  cutting-off  wheel.  You  can  use 
wheels  with  diameter  of  115mm.  The  maximum 
thickness in this case is 3 mm.

cutting stone material

When  cutting  stone  material  you  should  use  a 
flat  cutting  off  wheel.  You  can  use  wheels  with 
diameter of 115mm. Always approach the job at 
the  same  angle  at  which  you  would  like  to  cut. 
Maintain this angle during cutting and do not exert 
any side pressure on the wheel.

Inserting the wheels/ disks

Please  proceed  as  follows  when  inserting  the 
wheel/disk:
1.   Before mounting, remove the mains plug from 

the socket and move the on and off switch (1) 
to position 0! Ensure that the protective device 
is correctly installed.

2.   Place the internal flange (10) on the drive shaft 

(2). Ensure that it is in contact with the two flat 
areas.

3.   Now place the abrasive disk on the drive shaft 

(2) and the internal flange (10). Ensure that it 
is correctly in place.

4.   Now attach the external flange with the thread 

(9), ensuring that it is facing the rightdirection 
according  to  the  type  of  disk/wheel  used.  In 
the case of abrasive I disks, the flange (9) is 

inserted with the higher side pointing towards 
the disk. In the case of cutting off wheels, the 
flange (9) is inserted with the flat side pointing 
towards the wheel5. Depress and hold the lock 
button (7) so that cannot turn and then tighten 
the external flange (9) with the external flange 
spanner (8).

Flange arrangement

abrasive Disks

•   Ensure that the speed to which the machine is 

set is sufficient for the accessories chosen.

•   Use  only  abrasive  disks  with  a  diameter  of 

115mm!

•   Before  mounting  the  disk,  remove  the  mains 

plug from the socket and push the on and off 
switch (1) to position 0!

1   Place the internal flange (10) on to the drive 

shaft (2).

2.   Place the abrasive disk on the drive shaft (2) 

and ensure that it is correctly in place.

3.   Attach the external flange with the thread (9) 

and  tighten  it  as  described  above  with  the 
external flange spanner (8).

NOTE: 

Expect  a  “rain  of  sparks”  when  the  disk 

comes  into  contact  with  metal.  While  grinding, 
always  maintain  the  correct  angle  between  the 
disk  and  the  working  surface  of  15°.  This  pro

-

duces ideal results and avoids overloads.

Overload

The  motor  of  your  right  angle  grinding  machine 
may be damaged when overloaded. This results 
from  excessive  working  pressure  over  a  pro

-

longed  period.  Therefore  you  should  not  try  to 
accelerate  your  working  speed  by  increasing 

pressure  on  your  machine.  The  abrasive  disks 
work  more  efficiently  if  only  slight  pressure  is 
exerted on the grinding machine, thus avoiding a 
drop in the grinding speed.

MaINTENaNcE

•   The protective cover, air slits and motor hous

-

ing should be kept as free of dirt and dust as 
possible.

•   Rub  off  the  device  with  a  clean  cloth  or  use 

compressed air at a low pressure to blow out 
any dust or dirt. Excessive amounts of metal 
dust may result in electricity from the internal 
components  being  conducted  on  to  exposed 
metal parts!

•   Do  not  subject  the  grinding  machine  to  any 

overload! Overloading will lead to a reduction 
in the speed and performance and cause the 
machine  to  overheat!  If  this  should  happen, 
switch the grinding machine off and let it cool 
down for approximately 30 minutes or to room 
temperature!

NOTE: 

Turning off the grinding machine while it is 

being subjected to a load will reduce the working 
life of the operating switch!

cLEaNING aND caRE

•   Before  cleaning  the  machine,  remove  the 

mains  plug  from  the  socket  and  turn  the  on 
and off switch (1) to position 0!

•   For  cleaning  purposes,  only  use  a  slightly 

damp but not wet cloth!

•   Do not use any abrasive additives (petrol, tur

-

pentine etc) as these may damage the plastic 
housing!

•   A  mild  soap  is  suitable  for  cleaning  the 

machine!

•   Ensure  that  no  moisture  is  allowed  to  get 

inside the machine!

•   After  cleaning,  wipe  the  machine  with  a  dry 

cloth!
