Fitting
Remove the battery from the power tool before carrying out work on the power tool (e.g. maintenance, changing tool, etc.). The battery should also be removed for transport and storage. There is risk of injury from unintentionally pressing the on/off switch.

Inserting the Edge Router into the Router Plunge Base (see figure A)

– Open the clamping lever (13) if it is closed.
– Push the edge router (1) as far as it will go into the router plunge base (2).
– Close the clamping lever (13).
After assembly, always check that the edge router (1) is secure in the router plunge base (2).
Dust/Chip Extraction
The dust from materials such as lead paint, some types of wood, minerals and metal can be harmful to human health.
Touching or breathing in this dust can trigger allergic reactions and/or cause respiratory illnesses in the user or in people in the near vicinity.
Certain dusts, such as oak or beech dust, are classified as carcinogenic, especially in conjunction with wood treatment additives (chromate, wood preservative). Materials containing asbestos may only be machined by specialists.
– Use a dust extraction system that is suitable for the material wherever possible.
– Provide good ventilation at the workplace.
– It is advisable to wear a P2 filter class breathing mask.
The regulations on the material being machined that apply in the country of use must be observed.

Avoid dust accumulation at the workplace. Dust can easily ignite.

Connecting the Dust Extraction System (see figure B)
Insert the dust extraction adapter (17) into the router plunge base (2). Push the part of the
adapter (17) that is opposite the screw (18) into the router plunge base (2).
Fix the adapter in place using the screw (18).
Put an extraction hose (26) (dia. 35 mm) (accessory) on the installed dust extraction adapter (25). Connect the dust extraction hose (26) to a dust extractor (accessory).
The dust extractor must be suitable for the material being worked. When extracting dust that is dry, especially detrimental to health or carcinogenic, use a special dust extractor.

Operation

Setting the Routing Depth (see figure C)
The routing depth must only be set while the power tool is switched off.

Rough Adjustment of the Routing Depth using the Infinitely Variable Depth Stop and Scale
– Place the power tool with a fitted router bit onto the work- piece you want to machine.
– Set the scale for fine adjustment (10) to “0”.
– Set the turret stop (8) to the lowest setting; you will feel the turret stop engage.
– Loosen the handle screw for the depth stop (5) so that the depth stop (3) moves freely.
– Slowly guide the router (1) by pressing the handle (14) down slowly until the router bit is touching the workpiece surface. Push the locking lever (12) to lock the plunge depth.
– Push the depth stop (3) down until it is resting on the tur- ret stop (8). Set the slide with the index mark (4) to position “0” on the routing depth scale (11).
– Set the depth stop (3) to the required routing depth and tighten the handle screw for the depth stop (5). Take care not to accidentally move the index mark (4).
– Release the locking lever for the plunge action (12) and guide the router to the uppermost position.
The set routing depth is only reached when the depth stop (3) touches the turret stop (8) while plunging.
For larger routing depths, you should perform the cut in several phases, so that only a small amount of material is removed after each cut. By using the turret stop (8), the routing process can be divided into several steps.

Rough Adjustment of the Routing Depth using the Turret Stop Settings
– Place the power tool with a fitted router bit onto the work- piece you want to machine.
– Set the scale for fine adjustment (10) to “0”.
– Set the turret stop (8) to the lowest setting you require; you will feel the turret stop engage.
– Loosen the handle screw for the depth stop (5) so that the depth stop (3) moves freely.
– Slowly guide the router (1) by pressing the handle (14) down slowly until the router bit is touching the workpiece surface. Push the locking lever (12) to lock the plunge depth.
– Tighten the handle screw (5).
– By turning the turret stop (8), you can now set the depth using the predefined settings.

Example:
Required routing depth: 8 mm
First routing operation from setting “10” to setting “5” → 5 mm
Second routing operation from setting “5” to setting “2” → 3 mm
Note: For precision routing results, it is advisable to stay within the maximum routing depth of 5 mm per routing operation.

Fine Adjustment of the Routing Depth
After making a test cut, you can set the routing depth to the exact level you require by turning the bushing (9). Turning it clockwise increases the routing depth; turning it anticlockwise decreases the routing depth. The scale (10) can be used for guidance. One turn corresponds to an adjustment range of approx. 0.8 mm; the maximum adjustment range is approx. 4 mm (i.e. five turns correspond to 4 mm).
When the router plunge base (2) is lowered to the maximal plunge depth, it is not possible to use the fine adjustment to make deeper cuts, as the maximum adjustment range has been utilised.
Fine adjustment is also not possible when the depth stop (3) sits against the turret stop (8).
Working Advice
Routing Direction and Routing Process (see figure D)
Routing must always be carried out with the workpiece being moved against the direction in which the router bit is turning (up cut). If the workpiece is moved in the same direction as the router bit is turning (down cut), the power tool may be pulled out of your hands.

To rout with the router plunge base (2), proceed as follows:
– Set the required routing depth, (see “Setting the Routing Depth (see figure C) “, page 10).
– Place the power tool with a fitted router bit onto the workpiece you want to machine and switch on the power tool.
– Slowly guide the router (1) down until the set routing depth is reached. Push the locking lever (12) to lock the plunge depth.
– Carry out the routing process with a uniform feed.
– When routing is complete, move the router back to the uppermost position.
– Switch the power tool off.

Readjusting the Clamping Lever (see figure E)
When the router (1) is no longer secure in the router plunge base, the tensioning force of the clamping lever (13) must be readjusted.
– Open the clamping lever.
– Turn the nut approx. 45° clockwise with an open-ended spanner (8 mm).
– Close the clamping lever again.
– Check that the router is clamped securely. Do not overtighten the nut.

Attaching the Parallel Guide (see figure F)
Insert the guide holder (16) into the side guides on the router plunge base (2) and secure it with the two wing bolts (15).
Attach the parallel guide (19) to the guide holder (16) using the wing bolt (23).

Attaching Guide Rail 2 609 255 732 (see figure G)
Insert the guide holder (16) into the side guides on the router plunge base (2) and secure it with the two wing bolts (15).
Place the guide holder (16) on the guide rail (20).
Attaching Guide Rail 1 600 Z00 005 (see figure H)
Insert the adapter for the guide rail (24) into the guide holder (16) and secure it with the wing bolt (23).
Insert the installed guide holder (16) into the side guides on the router plunge base (2) and secure it with the two wing bolts (15).
Place the installed guide holder (16) on the guide rail (21).
Attaching the Centring Pin (see figure I)
You can use the centring pin (27) to rout circular areas.
Insert the guide holder (16) into the side guides on the router plunge base (2) and secure it with the two wing bolts (15).
Attach the parallel guide (19) without the movable slide piece to the guide holder (16) using the wing bolt (23).
Insert the centring pin (27) through the parallel guide (19).
Set the required radius (between the tip of the centring pin and the router bit). Fix the centring pin (27) in place using the associated wing bolt. Insert the centring pin (27) into a pre-drilled hole (dia. 4 mm). Start routing.

Attaching the Guide Bushing (see figure J)
Using the guide bushing (28), you can transfer contours from templates or patterns to the workpiece.
Select the guide bushing that is suitable for the thickness of the template or pattern. Due to the protruding height of the guide bushing, the template must have a minimum thickness of 8 mm.
Insert the guide bushing (28) into the guide plate (7) in the correct position.
Insert the hold-down device of the guide bushing (29) into the dust extraction adapter (17). The hold-down device clicks audibly into place.
Insert the adapter (17) together with the installed hold down device (29) into the router plunge base (2). Attach the adapter (17) using the screw (18)(see “Connecting the Dust Extraction System (see figure B)”, page 10).
