Not all the illustrated or described accessories are  included as standard delivery.
 
Read  all  instructions.
 
  Failure  to
follow  all  instructions  listed  below 
may  result  in  electric  shock,  fire 
and / or serious injury.
SAVE THESE INSTRUCTIONS.
 

 
Secure the workpiece.
 
 Clamping devices or a
vise will hold the workpiece in place better than the hand.
 

 
Always wait until the machine has come to 
a complete stop before placing it down.
 
 The
tool  insert  can  jam  and  lead  to  loss  of  control over the power tool.
 

 
Do  not  use  a  machine  with  a  damaged 
mains cable. Do not touch the damaged ca-
ble and pull the mains plug when the cable
is damaged while working.
 
 Damaged cables
increase the risk of an electric shock.
  Connect  machines  that  are  used  in  the open via a residual current device (RCD). 

 
Guide  the  machine  against  the  workpiece 
only when it is switched on.
 
 Otherwise there
may be danger of kickback when the tool insert jams in the workpiece.
 

 
Never  cut  over  metal  objects,  nails  and screws.
 
  The  tool  insert  could  become  dam-
aged. Danger of injury.
 

 
Check  the  tight  seating  of  the  routing  bit before starting operation.
 

 
The allowable speed of the tool insert must 
be at least as high as the maximum speed 
stated on the machine.
 
 Accessories driven in
excess  of  their  allowable  speed  can  be  de- stroyed.
 

 
The shank diameter of the tool insert must 
correspond  with  the  diameter  of  the  tool
holder (collet).
 
 Tool inserts that do not fit pre-
cisely  in  the  tool  holder  of  the  machine  rotate 
irregularly, vibrate heavily and can lead to loss of control.
 

 
Use only sharp, flawless tool inserts.
 
 Dam-
aged  or  unsharp  tool  inserts  can  break  or cause kickback.

Never touch the rotating tool insert.  Danger
of injury.
 Use  appropriate  detectors  to  determine  if 
utility  lines  are  hidden  in  the  work  area  or
call  the  local  utility  company  for  assis-tance. 
Contact with electric lines can lead to fire and 
electric  shock.  Damaging  a  gas  line  can  lead
to  explosion.  Penetrating  a  water  line  causes
property  damage  or  may  cause  an  electricshock.
 Hold  the  power  tool  only  by  the  insulated
handles,  when  performing  an  operation
where  the  tool  insert  can  run  into  hidden
wiring or its own mains cable.  Contact with
a “live” wire can make metal parts of the powertool “live” and lead to an electric shock.
The  machine  is  intended  for  trimming  edges  in
wood,  plastic  and  light  building  materials.  It  is
also  suitable  for  routing  of  grooves,  profiles  and slots as well as for contour routing.  Before any work on the machine itself, pull the power plug.
Assembling the Base Cover Sleeve  
(see figure  ) 
For  assembly  of  the  base  cover  sleeve  11,  re-
move  the  clamping  lever  10.  Place  the  base
cover  sleeve  11  onto  the  routing  base  2  from
above  and  reassemble  the  clamping  lever  10
again  in  such  a  manner  that  the  motor  unit  1  is
held  securely  in  the  routing  base  2  when  the
clamping lever is locked.
Disassembling the Motor Unit  
(see figure  ) 
For  disassembly  of  the  motor  unit  1,  open  the
clamping lever  10 and turn the routing base  2 to
the symbol “ ” on the motor unit. Then pull the motor unit  1 upwards out of the routing base  2.
Router Bit Selection 
Depending  on  the  processing  and  application, 
router bits are available in the most different de- signs and qualities: 
Router  bits  made  of  high  speed  steel (HSS) 
are  suitable  for  the  machining  of  soft  materials,
e. g., soft wood and plastics. Carbide  tipped  router  bits (HM)
  are  especially
suitable  for  hard  and  abrasive  materials,  e. g.,hard wood. 
Original router bits from the extensive Bosch ac- 
cessories program are available at your special- ized hardware store.
Inserting Router Bits  
(see figures  + )  Before any work on the machine itself, pull the power plug.
 It  is  recommended  to  wear  protective  gloves
when inserting or replacing router bits.
Disassemble  the  motor  unit  as  described  in  therespective section. 
Press the spindle locking button  9 and keep it de-
pressed. If need be, turn the spindle by hand until the lock engages.  Press  the  spindle  lock  button  only  when  at  a standstill.
Loosen  the  tightening  nut  5  with  an  open-end
spanner  13  (size 17 mm)  by  turning  it  several
times, but do not unscrew the tightening nut. 
Insert the shank of the router bit  4 as far as it will
go into the collet.
Tighten  the  tightening  nut  5  with  the  open-end
spanner  13 (size 17 mm) and release the spindle
locking button  9.
Do not tighten the tightening nut of the collet without a router bit inserted.

Mounting the Motor Unit  
(see figure  ) 
With  the  clamping  lever 10  opened,  mount  the
motor unit  1 by placing it into the routing base  2.
 Make sure that the  “ ” mark on the routing
base 2  points  toward  the  line  under  the 
“ ”  symbol on the motor unit 1.  Otherwise
the machine can be damaged.
 After mounting, always check if the motor unit 
sits tightly on the routing base. The pre-tension
of the clamping lever can be changed by read- justing the nut
After  mounting,  has  taken  place,  set  the  routing base  2 to the “ ” symbol on the motor unit  1 and
lock the clamping lever  10.
Always use the correct voltage:  The voltage of
the power source must agree with the values onthe nameplate of the machine.
Switching On and Off To  start  the unit, move the On/Off switch  12 to I.
To  switch off  the unit, move the On/Off switch  12
to  0.
 Adjust the depth-of-cut only when the trimmer is switched off.
Place the trimmer on the workpiece to be worked. 
Open  the  clamping  lever  10,  turn  the  routing
base  2  to  the  “ ” symbol  and  slowly  lower  the
motor  unit  until  the  router  bit  touches  the  work- 
piece. Fix the motor unit in this position by locking the clamping lever  10.
Read  the  measuring  value  off  the  scale  8  and
note  it  down  (zeroing).  Add  the  desired 
depth-of-cut to this value. 
Open  the  clamping  lever  10  and  set  the  motor
unit  to  the  calculated  scale  value.  Turn  the  rout- 
ing base  2 to the “ ” symbol and lock the clamp-
ing lever  10 again.
Check  the  adjusted  depth-of-cut  with  a  trial  cutand correct it, if necessary. 
For  fine  adjustment  of  the  depth-of-cut,  set  the 
motor unit with the clamping lever  10 open to the
“ ” symbol. Adjust the desired depth-of-cut with 
the knurled screw  3. Afterwards, lock the clamp-
ing  lever  to  securely  lock  the  motor  unit  in  the routing base. Direction of Feed (see figure  ) 
The  feed  motion  of  the  trimmer  must  always  be 
carried  out  against  the  rotation  direction  of  the 
router bit (up-grinding). 
When  milling  in  the  direction  with  the  rotation  of 
the router bit (down-cutting), the router can breakloose, eliminating control by the user. Routing Process 
Use the machine only with the routing base mounted.   Loss  of  control  over  the  machine
can cause injuries.
 Before beginning the routing procedure, check 
if  the  routing  base  2  is  positioned  at  the
“ ” symbol on the motor unit  1.
Adjust the depth-of-cut as described previously. 
Place the machine onto the workpiece and switch 
it on with the On / Off switch  12.
After finishing the cutting process, switch the ma- 
chine off with the On / Off switch  12.
Routing with Guide Bushing 
The guide bushing  15 enables template and pat-
tern routing on workpieces. 
Inserting the Guide Bushing 15  
(see figure  ) 
Unscrew  the  4 pan  head  screws  on  the  bottom 
side  of  the  guide  plate  6  and  remove  the  guide
plate.  Insert  the  guide  bushing  into  the  guide plate and fasten it again to the base plate. Routing Process
Select a router bit with a smaller diame- 
ter than the inside diameter of the guidebushing.
Place  the  machine  with  the  guide  bushing  15
against the template. 
Guide  the  machine  with  the  projecting  guide 
bushing along the template, applying slight lateralpressure. Note:  The template must have a minimum thick-
ness of 8 mm, due to the projecting height of the guide bushing.

Shaping or Molding Applications  
(see figure  ) 
For  shaping  or  molding  applications  without  the 
use  of  a  parallel  guide,  the  router  must  beequipped with a pilot or a ball bearing. 
Guide the machine from the side to the workpiece 
until  the  pilot  or  the  ball  bearing  of  the  trimmer 
faces  against  the  workpiece  edge  to  be  worked.
Guide  the  machine  along  the  edge  of  the  work-
piece,  ensuring  rectangular  support.  Excessive 
pressure can damage the edge of the workpiece. Routing with Parallel Guide  
(see figure  ) 
Fasten  the  parallel  guide 17  to  the  routing  base
with the wing bolt  16.
Adjust  the  desired  depth  setting  on  the  parallel guide  18 with the wing bolt.
Guide the machine with uniform feed and lateral
pressure  against  the  parallel  guide  17  along  the
edge of the workpiece.
Routing with the Curve Buffer  
(see figure  ) 
The  curve  guide  19  is  used  for  the  routing  of
rounded edges using routing bits without pilot or ball bearing. 
Fasten  the  curve  guide  19  to  the  routing  base
with wing bol  16.
Guide  the  machine  with  uniform  feed  along  the edge of the workpiece. Lateral Clearance
In  order  to  change  the  amount  of  material  re- 
moval,  the  lateral  clearance  between  workpiece 
and the guide roller of the curve guide can be ad- justed. 
Loosen wing bolt  21, set the desired lateral clear-
ance  by  readjusting  wing  bolt  20,  then  tighten
wing bolt  21 again.
Height
Adjust  the  vertical  alignment  of  the  curve  guide 
depending on the router bit in use and the thick- ness of the material to be worked. 
Loosen the wing bolt  16 on the curve guide, slide
the  curve  guide  to  the  desired  position  and tighten the wing bolt again. 
Before any work on the machine itself, pull the power plug.
 For safe and proper working, always keep the
machine and its ventilation slots clean.
Should the machine fail in spite of careful manu- 
facturing and testing, its repair should be carried 
out  by  a  Bosch  power  tools  authorized  serviceagent. 
In  all  correspondence  and  spare  parts  orders, 
please always include the 10-digit article number given on the nameplate of the machine. 
Recycle  raw  materials  instead  of  disposing them as waste 
The machine, its accessories and packaging ma- 
terials  should  be  sorted  for  environmentally- 
friendly recycling. 
These instructions are printed on chlorine-free re- cycled paper. 
The  plastic  components  are  labeled  for  catego- rized recycling.
