Maintenance And Service; Maintenance And Cleaning - Bosch GMF 1600 CE Professional Manual Original

Roughly set the required radius by moving the router com-
pass and tightening the wing bolts (44) and (45).
Then loosen the wing bolt (45) and use the knob (46) to
fine-adjust the length. One revolution corresponds to an ad-
justment range of 2.0 mm. Each of the graduation marks on
the knob (46) changes the adjustment range by 0.1 mm.
Switch the power tool on and move it over the workpiece us-
ing the right handle (4) and the handle for the router
compass (43).
Routing with a guide rail (see figure M)
You can use the guide rail (49) to rout in straight lines.
To level out the height difference, you must fit the spacer
plate (48).
Fit the router compass/guide rail adapter (42) as shown in
the figure.
Fasten the guide rail (49) to the workpiece using suitable
clamping devices, e.g. screw clamps. Put the power tool
with mounted guide rail adapter (42) on the guide rail.
Routing with the guide bushing (see figures N–Q)
Using the guide bushing (53), 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.
In order to use the guide bushing (53), the SDS guide-bush-
ing adapter (50) must first be inserted into the guide
plate (14).
Place the guide-bushing adapter (50) from above onto the
guide plate (14) and tighten it firmly with the 2 fastening
screws (51). Ensure that the release lever for the guide-
bushing adapter (52) is freely movable.
Push the release lever (52) in the direction of the arrow and
insert the guide bushing (53) from below into the SDS
guide-bushing adapter (50). The coding cams must audibly
click into the recesses of the guide bushing (53).
Check the clearance from the router bit centre and guide-
bushing edge (see "Centring the base plate (see figure R)",
page 25).
Select a router bit with a diameter that is smaller than
u
the interior diameter of the guide bushing.
Routing process
Note: Be aware that the router bit (18) always protrudes
slightly from the base plate (13). Do not damage the tem-
plate or the workpiece.
Switch the power tool on and move it with the guide
bushing (53) towards 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 routing depth is reached. Let go of the release
lever (7) again in order to lock the plunging depth.
Guide the power tool with the protruding guide bushing (53)
along the template using lateral pressure.
Bosch Power Tools
Centring the base plate (see figure R)
To ensure that the distance from the router bit centre to the
guide-bushing edge is uniform, the guide bushing (53) and
the guide plate (14) can be adjusted to each other, if re-
quired.
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 routing depth is reached. Let go of the release
lever (7) again in order to lock the plunging depth.
Loosen the fastening screws (54) approx. two turns so that
the guide plate (14) is freely movable.
Insert the centring pin (55) into the tool holder as shown in
the figure. Hand-tighten the cap nut so that the centring 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).
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.
Working with a router table (see figure S)
The non-plunge base (3) can be used with a suitable router
table. To install the router, remove the guide plate (14) and
fasten the non-plunge base (3) to the router table with the
fastening screws (56).
When mounting the non-plunge base, please observe
u
the operating instructions of your router table. If ne-
cessary, matching holes must be drilled into the router
table in order to mount the non-plunge base.
For fine adjustment of the routing depth, it is best to use the
specialty hex key (57).
Routing with an extraction hood (see figures T–U)
For routing edges, the extraction hood (58) can additionally
be used.
Fasten the extraction hood (58) to the base plate (13) with
the two screws (59). The extraction hood (58) can be
fastened in three different positions, as shown in the figure.
Remove the extraction hood again for routing smooth plane
surfaces.

Maintenance and Service

Maintenance and Cleaning

Pull the plug out of the socket before carrying out any
u
work on the power tool.
To ensure safe and efficient operation, always keep
u
the power tool and the ventilation slots clean.
In extreme conditions, always use a dust extractor if
u
possible. Clean ventilation slots frequently using a
brush and install a residual current device (RCD) up-
stream. When machining metals, conductive dust can
settle inside the power tool, which can affect its protect-
ive insulation.
