When fitting the new trimmer disc always make sure that the
locking pins fit comfortably in the stabiliser holes of the
trimmer disc. Tighten the screw (5) with the Allen key by
turning it clock-wise.
After tightening the screw check the rotation of the disc by tur-
ning it manually. If the disc touches then it should be re-
moved, turned by 180o, and then replaced. The plastic cover
M5 (see small parts set) will avoid impurities of the socket
head screw. Close the front cover making sure that the spacer
ring is present on the hinge-bolt. Plug in and re-open the
shut-off valve.
6.2 Changing / Cleaning of the support flange:
Remove the trimmer disc as per previous instructions.
Next, use the screw (7) and Allen key SW8 (3) to ease off the
support flange (8) from the motor shaft and clean the working
area and the support flange. When cleaning the working area
make sure that no water gets through the opening for the
motor shaft into the motor compartment. Remove the screw
from the support flange again. After rubbing a little Vaseline
into the motor shaft and the black rubber washer on the
support flange push the support flange back onto the motor
shaft. Take note of the position of the take-up on the motor
shaft and the position of the take-up nut on the support
flange. These must match. Replace the trimmer disc as per
the instructions in point 6.1.
6.3 Changing / Cleaning the spray pipe:
Switch off the unit, unplug (11), close the shut-off valve and
open the front cover (2) as described in point 6.
Remove the spray pipe (15) from the water supply pipe by
gently moving it back and forth. Remove the washers and
place them in a suitable de-scaling liquid. After successfully
cleaning the washers replace them, smear them with a bit of
Vaseline and gently feed the spray pipe back into the water
supply pipe. Close the front cover. Ensure that the spacer ring
is present on the hinge-bolt. Replace the plug and re-open the
shut-off valve.
6.4 Changing / Cleaning the grinding platform:
The trimmer table (1) is easily cleaned under running cold
water. It can be unhinged from the front plate by pulling it
upwards off the adjuster screw and then pulling it sideways.
When replacing it the trimmer table is pushed diagonally from
above into the trimmer opening. The trimmer table will only
lock into the adjuster screw hole (2.3) when the lip (2.1) has
snapped on over the edge. In order to ensure a secure hold
the trimmer table sides (2.2) must be pressed into the front
cover recesses. Always make sure that the trimmer table is
seated correctly! To adjust the trimmer table (only for KFO
90o) first unscrew the knurled nut (2.4) clockwise and reset the
trimmer table via the adjuster screw. After adjusting turn the
knurled nut anticlockwise to counter the threaded socket.
98° and 90° trimmer tables are available. To make the
mounting of the trimmer table easier they can be sprayed in
advance with some silicon oil or with washing liquid.
Always make sure that the trimmer table is seated
correctly on the front cover!
