steps to start with. The clearance of the steps can be
changed by screwing the adjusting screws (10) further in or
out.
After making a test cut, you can set the routing depth to the
exact level you require by turning the knob (25). Turning it
clockwise increases the routing depth; turning it anticlock-
wise decreases the routing depth. The scale (24) can be
used for guidance. One revolution corresponds to an adjust-
ment range of 2.0 mm. Each of the graduation marks on the
bottom edge of the scale (24) changes the adjustment range
by 0.1 mm. The maximum adjustment range is ±8 mm.
Example: The required routing depth should be 10.0 mm,
and the test cut resulted in a routing depth of 9.6 mm.
– Turn the scale (24) to 0.
– Turn the adjustment knob (25) clockwise by 0.4 mm/4
graduation marks (difference between target and actual
value).
– Check the selected routing depth by performing another
test cut.
GOF 1250 CE: After setting the routing depth, do not
change the position of the slide (27) on the depth stop (14)
any more to ensure that you can always read the current
routing depth on the scale (26).
GOF 1250 LCE: The current routing depth is shown on the
display (21).

Working Advice

Protect router bits against shock and impact.
u
Routing direction and routing process (see figure F)
Routing must always be carried out with the work-
u
piece being moved against the direction in which the
router bit (5) 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.
Set the required routing depth (see "Setting the routing
depth", page 19).
Place the power tool with a fitted router bit onto the work-
piece you want to machine and switch on the power tool.
Push the release lever (23) back and guide the router as far
as it will go in the direction of the base plate (13). Let go of
the release lever (23) again in order to lock the plunging
depth.
Carry out the routing process with a uniform feed.
When routing is complete, move the router back to the
highest position.
Switch the power tool off.
Routing with an auxiliary guide (see figure G)
For machining large workpieces, e.g. when routing grooves,
you can fasten a board or straight edge securely to the work-
piece as an auxiliary guide. The router can be guided along
the path of this auxiliary guide. Move the router on the
flattened side of the guide plate along the auxiliary guide.

Edge or profile routing
For edge and profile routing without a parallel guide, the
router bit must be fitted with a pilot pin or a ball bearing.
While it is switched on, guide the power tool towards the
workpiece from the side until the pilot pin or the ball bearing
of the router bit is touching the side of the workpiece edge
that you want to machine.
Guide the power tool along the workpiece edge. Pay atten-
tion that the router is positioned perpendicularly. Too much
pressure can damage the edge of the workpiece.
Routing with a parallel guide (see figure H)
Slide the parallel guide (33) with the guide rods (34) into
the base plate (13) and tighten it with the screws (7) ac-
cording to the required dimension.
Additionally, the parallel guide can be adjusted lengthwise
with the wing bolts (36) and (35).
Fine adjustment of the length is possible with the adjustment
knob (37) after loosening both wing bolts (35). One revolu-
tion corresponds to an adjustment range of 2.0 mm. Each of
the graduation marks on the knob (37) changes the adjust-
ment range by 0.1 mm.
The effective contact surface of the parallel guide can be ad-
justed with the fence (38).
While it is switched on, guide the power tool along the work-
piece edge with a uniform feed and while applying lateral
pressure to the parallel guide.
When routing with the parallel guide (33), the dust/chip ex-
traction should take place via the special extraction ad-
apter (39). The extraction adapter can remain fitted.
Routing with the Circle Cutting Adapter (Accessory)
You can use the circle cutting adapter for circular routing
work.
Routing with the Guide Rail (Accessory)
You can use the guide rail and guide rail adapter to rout in
straight lines.
Routing with the guide bushing (see figures I–L)
Using the guide bushing (43), 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 (43), the SDS guide-bush-
ing adapter (40) must first be inserted into the guide
plate (11).
Place the guide-bushing adapter (40) from above onto the
guide plate (11) and tighten it firmly with the 2 fastening
screws (41). Ensure that the release lever for the guide-
bushing adapter (42) is freely movable.
Push the release lever (42) in the direction of the arrow and
insert the guide bushing (43) from below into the SDS
guide-bushing adapter (40). The coding cams must audibly
click into the recesses of the guide bushing (43).
