ASSEMBLY AND ADJUSTMENTS
WARNING: To reduce the risk of
injury, turn unit off and disconnect
machine from power source before
installing and removing accessories,
before adjusting or changing set-
ups or when making repairs. Be sure
the trigger switch is in the OFF position.
An accidental start-up can cause injury.
Inserting and Removing a Cutter
(fi g. 2)
1. Press and hold down the spindle lock (b).
2. Using the wrench supplied, loosen the collet nut
(c) a few turns and insert a cutter (dd).
3. Tighten the collet nut and release the spindle
lock.
WARNING: Never tighten the collet nut
without a cutter in the collet.
Replacing the Collet Assembly
(fi g. 3)
Your router is supplied with a 8 mm (GB: 1/4") or
12 mm (1/2") collet fitted to the tool. Two other
precision collets are also available to suit the cutter
used. The collet and the collet nut are inseparable.
1. Loosen the collet nut (c) completely.
2. Remove the collet assembly (u).
3. Fit a new assembly and tighten the collet nut (c).
Setting the Electronic Speed
Control Dial (fi g. 1)
The speed is infinitely variable from 8,000 to 24,000
min -1 using the electronic speed control dial (s) for
uniform cutting results in all types of wood, plastics
and in aluminium.
Turn the electronic speed control dial to the required
level.
Generally, use the low setting for large diameter
cutters and the high setting for small diameter
cutters. The correct setting, however, is a matter of
experience.
1 = 8,000 min

2 = 9,500 min

Adjusting the Depth of Cut (fi g. 4)
Your router is equipped with a high-precision depth
adjustment system including a zero reset ring for
both the quick adjuster and the fine adjuster.
QUICK ADJUSTMENT USING THE GRADUATION
WITH ZERO RESET RING
1. Loosen the depth stop locking bolt (n).
2. Unlock the plunge limiter (o) by turning it
counterclockwise.
3. Lower the router carriage until the cutter is in
contact with the workpiece.
4. Tighten the plunge limiter (o).
5. Set the quick adjuster (p) to zero using the ring
(v). The depth stop (m) must be in contact with
the revolver depth stop (l).
6. Adjust the depth of cut using the quick adjuster
(p) and the corresponding graduation. The
adjusted depth of cut is indicated by the
arrows (w).
7. Tighten the depth stop locking bolt (n).
TRIPLE DEPTH ADJUSTMENT USING THE
REVOLVER DEPTH STOP
The revolver depth stop (l) can be used to set three
different depths. This is particularly useful for deep
cuts, performed in steps.
– Place a depth template between the depth
stop (m) and the revolver depth stop (l) to
adjust the exact cutting depth.
– If required, set all three screws.
FINE ADJUSTMENT
When not using a depth template, or if the depth of
cut needs readjustment, it is recommended to use
the fine adjuster (q).
