KRESS 6901, Operating Instructions Manual

Safety r

ules and instructions which

should be read prior to operation and
strictly observed:

1. Pull mains plug prior to working

on the motor. This applies above
all to clamping cutters and all
other tools as well as during ser-
vice jobs.

2. Hold tools well or clamp.
3. Always feed the workpiece

against the direction of rotation of
the cutter (up-cutting). Important
when cutting along edges.

4. Make sure that the cutting tools

are always sharp. Blunt tools
result in poor cutting and unne-
cessary overload of motor.

5. A uniform and not too excessive

feed will extend the life of the cut-
ter, will prevent burns on wood
and protect the motor against
overloads.

6. Caution! Keep hands clear of cut-

ter (Danger of serious injury!).

7. Make sure that the machine is

switched off when removing
motor.

8. Pull mains plug as a protection

against unauthorized operation
whenever the work is interrupted
for extended periods.

9. We recommend wearing a face

mask if you perform extensive
grinding work without a suction
unit.

10. We recommend wearing ear pro-

tectors for long periods of work.

11. Do not work with materials con-

taining asbestos!

12. Outside power sockets must be

protected with residual-current-
operated circuit-breakers
(r.c.c.b.).

13. Do not drill holes into the hous-

ing to label the machine. The pro-
tective insulation will be bridged.
Please use self-adhesive labels.

14. Damaged mains cables must not

be used. They are to be replaced
immediately by an electrician.

Initial operation

Befor

e the first operation check that the

mains voltage corresponds to that given
on the machine nameplate.

Clamping of tools into r

outing and

grinding motor

The spindle of the r

outing and grinding

motor is provided with a precision 
collet for mounting tools.
To clamp tool (1), the motor spindle (2) is
held with a size 14 open-end wrench
and the clamping nut (3) is tightened
with a size 17 open-end wrench.
To remove tools release collet (4) first by
furning clamping nut (3) once-again
using the two size 14 and 17 open-end
wrenches – and then remove tool (1)
after a few additional turns. The clam-
ping nut (3) and collet (4) must be flush
at front end. If not, remove both compo-
nents from machine. Then push collet
into clamping nut in such a manner that
collet engages and both components
are flush.

Collet change
An annular spring (5) holds collet in

clamping nut. Energetic pulling will
release collet (4) from clamping nut (3).
Apply heavy pressure to engage new
collet and clamping nut.

Attention!

Never tighten clamping nut when no
tool is inserted. Collet might be 
compressed excessively and suffer
damage.

Attention!
To  prevent accidents always pull
mains plug when changing tools and
mounting accessories.

Switching on and off

The slide switch on the motor housing is

used to turn the machine on.

Switch position I: 

Motor running.

Switch position O: 

Motor not 
running.

Switch on machine prior to pushing 

tool against workpiece.

Adjustment of cutting depth
Refer to appr

opriate information in 

operating instructions for your drilling
and cutting unit.

Guar

d (special accessory)

The mounting plate (1) for the guar

d (2)

is inserted between the routing motor
and the arm of the drilling rig. The 4
rubber supports (Ø 6 x 3) are pushed
into the mounting plate (1) drill holes.
They ensure torsion-safe fastening.
Clamp motor into mounting bracket of
drilling rig. Screw guard with cyl. head
screws (5) to mounting plate (1)
adding washers (3) and snap rings (4).
The guard is provided with 2 bores on
both sides allowing it to be swung up
completely when the different mount-
ing brackets of drilling rigs are used
(make sure to use the correct bore).

W

orking with routing (cutting) motor

When using a drilling rig or a drilling

and cutting unit – in conjunction with a
cutting table, if required – pay attention
to information in operating instructions
enclosed there.
Also make sure that the fences are set
as closely as possible against the mil-
ling cutter and that the cutter guard is
set down as closely as possible in the
direction of the work surface. At the
same time make sure that the equip-
ment used for cutting jobs always gua-
rantees safe guiding of the work, for
example fence, auxiliary stop, feeding
slide or anti-kickback device during
routing jobs. Always select feeding
direction of work against direction of
rotation of cutter (up-cutting).

Example of fixed mounting, with the
workpiece being fed to the machine:

Attention!

Never use down-cutting method!

Free-hand jobs

Because of its small dimensions and

light weight the routing grinding motor
is also excellently suited for many free-
hand jobs.
