Description
This application example describes how to cut out weather-beaten linseed
oil putty beds with the putty router KF 5 EBQ.
The renovation of painted windows not only requires new paint. The best coat
is useless if the linseed oil putty bed is cracked or partly destroyed. Rain and
condensation can then get under the new coat, causing it to flake and exposing
the wood.

Preparation/set-up
Preparing the putty router:
Place window sash securely in position and clamp it.•
Fit the router bit in the putty router (cutter diameter - see above -•
depends on the putty bed width: dia. 10 mm, dia.12 mm, dia. 16 mm)
Set the speed to level 6.•
Mount the putty router on the window sash.•
Place the support (1) on the glass and tighten with the rotary knob (2)•
(see Fig. 508/5).
Place a piece of cardboard under the cutter onto the glass to ensure the•
glass is a safe distance away during cutting.
Move the putty router with the cutter until the cutter is on the cardboard.•
Move the stop of the routing depth setting against one of the three turret•
stops.
Connect the extractor hose to the tabletop of the KF 5.•

Setting the routing width:
Mount side stop with fine adjustment on tabletop.•
Push side stop against window sash.•
Make the rough adjustment of the cutter position using the linkage of the•
side stop.
Set the side stop with the fine adjustment (see Fig. 508/6) so that the•
cutter cleanly cuts out the putty in the glazing rebate.
Tip: On old windows, the wood can be recut until a straight putty rebate
edge guarantees perfect sealing.

Procedure
Switch on machine and plunge in. When routing, ensure that the side•
stop always makes contact with the window sash (see Fig. 508/7) and the
machine is flat on the surface of the window sash.
In order to cut right into the corner, in the area of the crossbar the•
chip protection is pulled upwards until it disappears in the router table
(see Fig. 508/8).
Always route in reverse direction to ensure to the longest possible•
service life of the cutters.
Windows with weatherboards at front
In order to cut right into the corner on windows with weatherboards, a
wooden base as high as the weatherboard must be fitted on the left and
right of the upright sash (see Fig. 508/9). Chip flutes are cut out at the
wooden bases to ensure that the fastening clamps do not obstruct the side
stop of the putty router (see Fig. 508/10). With this device, the putty can be
cut out comfortably and reliably from the two sashes and the weatherboard.
Upon completion of this work, corner areas can be reworked if necessary
with the firmer chisel and new putty can be applied.
