The length can be fine adjusted with the fine-adjustment knob
46 after loosening the wing bolt 45. One revolution corre-
sponds with a setting range of 2.0 mm. One graduation mark
on the fine-adjustment knob 46 changes the setting range by
0.1 mm.
Guide the switched on power tool over the workpiece with the
right handle 4 and the router compass handle 43.
Routing with Guide Rail (see figure M)
Straight routing cuts can be carried out with help of the guide
rail 49.
The base spacer 48 must be mounted in order to compensate
the height difference.
Mount the router compass/guide-rail adapter 42 as shown in
the figure.
Fasten the guide rail 49 to the workpiece with suitable clamp-
ing devices, e. g. screw clamps. Place the machine with the
guide-rail adapter 42 mounted onto the guide rail.
Routing with Guide Bushing (see figures N–Q)
The guide bushing 53 enables template and pattern routing
on workpieces.
In order to use the guide bushing 53, the guide bushing adapt-
er 50 must be inserted into the guide plate 14 first.
Place the guide bushing adapter 50 from above onto the
guide plate 14 and tighten it firmly with the 2 fastening
screws 51. Pay attention that the release lever for the guide
bushing adapter 52 is freely movable.
Choose a suitable guide bushing, depending on the thickness
of the template or the pattern. Because of the projecting
height of the guide bushing, the template must have a mini-
mum thickness of 8 mm.
Actuate the release lever 52 and insert the guide bushing 53
from below into the guide bushing adapter 50. Ensure that
the encoding keys clearly engage in the grooves of the guide
bushing.
Check the clearance from router bit centre and guide bushing
edge, see section "Centring the Base Plate".
Select a router bit with a diameter smaller than the in-
terior diameter of the guide bushing.
For routing with the guide bushing 53 proceed as follows:
– Note: Take into consideration that for routing work with
the non-plunge base 3, the router bit 18 always protrudes
out of the base plate 13. Do not damage the template or
the workpiece.
– Guide the switched on power tool with the guide bushing
toward the template.
– When using the plunge base 2: Press the release lever for
plunge action 7 down and slowly guide the router down un-
til the set depth-of-cut is reached. Let go of release lever 7
again to lock this plunging depth.
– Guide the switched on power tool with the protruding
guide bushing alongside the template applying lateral
pressure.

Centring the Base Plate (see figure R)
To ensure that the distance from router bit centre and guide
bushing edge is uniform, the guide bushing and the guide
plate can be adjusted to each other, if required.
– When using the plunge base 2: Press the release lever for
plunge action 7 down and guide the router toward the base
plate to the stop. Let go of release lever 7 again to lock this
plunging depth.
– Loosen fastening screws 54 approx. 2 turns, so that guide
plate 14 can move freely.
– Insert the centring pin 55 into the tool holder as shown in
the figure. Hand-tighten the tightening nut so that the cen-
tring pin can still be moved freely.
– Align the centring pin 55 and the guide bushing 53 to each
other by slightly moving the guide plate 14.
– Retighten the fastening screws 54 again.
– Remove the centring pin 55 from the tool holder.
– When using the plunge base 2: Press the release lever for
plunge action 7 and guide the router back to the upper-
most position.
Operation with Router Table (see figure S)
The non-plunge base 3 can be used with a suitable router ta-
ble. To install the router, remove the guide plate 14 and fas-
ten the non-plunge base 3 to the router table with the fasten-
ing screws 56.
For mounting of the non-plunge base, please observe
the operating instructions of your router table. If neces-
sary, matching holes must be drilled into the router table in
order to mount the non-plunge base.
For fine adjustment of the depth-of-cut, it is best to use the ex-
tension 58 or the specialty Allen key 57.
Routing with Extraction Hood (see figures T–U)
For routing edges, the extraction hood 59 can additionally be
used.
– Fasten the extraction hood 59 with the 2 fastening screws
60 to the base plate 13. The extraction hood 59 can be fas-
tened in 3 different positions, as shown in the figure.
– Remove the extraction hood again for routing smooth
plane surfaces.

Maintenance and Service

Maintenance and Cleaning

Before any work on the machine itself, pull the mains
plug.
For safe and proper working, always keep the machine
and ventilation slots clean.
In extreme conditions, always use dust extraction as
far as possible. Blow out ventilation slots frequently
and install a residual current device (RCD). When work-
ing metals, conductive dust can settle in the interior of the
power tool. The total insulation of the power tool can be im-
paired.
If the machine should fail despite the care taken in manufac-
turing and testing procedures, repair should be carried out by
an after-sales service centre for Bosch power tools.
