6.2 Speed control (Fig. 18 – Item 11)
The best speed depends on the material and the
diameter of the cutter. Select a speed between
11,000 and 30,000 rpm using the speed control
switch (11). You can choose from 6 different switch
positions. The speeds in the various switch positions
are as follows:
Switch position 1: approx. 11,000 rpm (minimum
speed)
Switch position 2: approx. 16,000 rpm
Switch position 3: approx. 21,000 rpm
Switch position 4: approx. 25,000 rpm
Switch position 5: approx. 29,000 rpm
Switch position 6: approx. 30,000 rpm (maximum
speed)
To increase the speed:
Move the speed control switch (11) in the plus
direction.
To reduce the speed:
Move the speed control switch (11) in the minus
direction.
6.3 Adjusting the routing depth (Fig. 12 – 16)
Place the machine on the workpiece.
n
Undo the wing screw (16) and fixing handle (9).
n
Slowly move the machine downwards until the
n
cutter makes contact with the workpiece.
Tighten the fixing handle (9).
n
Set the fine adjuster (20) to 0 as shown in Fig.
n
13.
Adjust the revolver end stop (14) so that the
n
depth stop (19) is above the end stop (15) set to
the lowest height.
Lower the depth stop (19) until it touches the end
n
stop (15). Then tighten the wing screw (16).
Set the pointer (17) to the zero point on the scale
n
(18).
Undo the wing screw (16). Push the depth stop
n
(19) upwards until the pointer (17) points at the
required cutting depth on the scale (18). Tighten
the wing screw again.
Test the setting by completing a test cut on a
n
waste piece.
Now you can carry out the final adjustment of the
n
cutting depth. To do this turn the fine adjuster
(20) to the required dimension.
Turn the fine adjuster (20) counter-clockwise: greater
cutting depth
Turn the fine adjuster (20) clockwise: lower cutting
depth
Turning the fine adjuster (20) through one division
corresponds to a change of cutting depth of 0.1 mm,
one whole turn corresponds to 1 mm.
6.4 Routing
To avoid damage to the router, make sure there
n
are no foreign objects attached to the workpiece.
Connect the mains plug to a suitable socket.
n
Hold the tool using both of its handles (7).
n
Place the router on the workpiece.
n
Set the cutting depth as described in point 6.3.
n
Select the speed as described in point 6.2 and
n
switch the machine on (see point 6.1).
Test the machine settings using a piece of
n
waste.
Operate the tool at full speed. Only then should
n
you lower the router to its working height and
lock the machine with the locking grip (9).
Cutting direction: The cutting tool turns clockwise.
To avoid accidents you must always cut against the
direction in which the tool turns (Fig. 19).
Feed speed: It is very important to machine the
workpiece at the correct feed speed. We recommend
that before you machine the actual workpiece, you
carry out several trial cuts on a waste piece of the
same type. This will enable you to find the best
working speed for the workpiece very easily.
Feed speed too low:
The cutter could heat up excessively. If you are
cutting inflammable material such as wood, the
workpiece could ignite.
Feed speed too high:
The cutter could be damaged. Cutting quality: Rough
and uneven.
Allow the cutter to come to a complete standstill
before removing the workpiece or putting down
the router.
6.5 Routing in stages
Depending on the hardness of the material you wish
to cut and the cutting depth, it may be a good idea to
proceed in stages.
Adjust the end stops as described in point 5.7.
n
If you wish to route in several stages, turn the
n
end stop revolver (14) after you have set the
cutting depth as described in point 6.3 so that the
depth stop (19) is over the highest end stop (15).
Now route in this setting. After completing the
n
first routing operation, adjust the end stop
