Thickness Planing

A
Danger!
− Entanglement hazard by the rotat-
ing feed rollers! Do not reach into
the machine! Use a feeding aid
(push stick) if you want to feed
short stock into the thicknesser.
− Do not jam work pieces. Risk of
kickback.
− Remove stuck stock only after
motor has come to a complete
stop and machine is unplugged.
− Guide a work piece on the out-
feed side if it has been fed so far
into the thicknesser that it can no
longer be safely guided from the
infeed side.
− Do not thickness plane more than
two workpieces at the same time.
In this case feed both workpieces
near the outer edges of the thick-
nesser bed.
− Use if necessary:
Dust collection device (optional
accessory);
sliding wax to enhance the glid-
ing of work pieces across the
infeed and outfeed table.
A
Caution!
There is a limit switch inside
the machine. Take care not to damage
the limit switch when feeding work
pieces.
1. Assume proper operating position:
− on the switch side;
− head-on to the machine;
2. Set planing thickness with the crank.
3
Note:
The machine can remove 3 mm
maximum in a single pass. This meas-
ure, however, shall only be used:
− with very sharp planer knives;
− for soft woods;
− if the full planing width is not utilized.
Otherwise there is a risk of overloading
the machine. It is best to make several
passes to bring the work piece down to
the desired thickness.
3. To thickness plane stock which sur-
faces are not parallel, use suitable
feeding aids (make fitting tem-
plates).
22
4. Set selector switch to thickness
planing.
5. Start motor.
6. Feed work piece slowly and straight
into the thicknesser. It will then be
automatically fed through the thick-
nesser.
7. Guide work piece straight through
the thicknesser.
8. Switch machine off if no further
thicknessing is to be done immedi-
ately afterwards.

7. Care and Maintenance

A
Danger!
Prior to all servicing:
− Switch machine OFF.
− Unplug power cable.
− Wait until machine has come to a
complete stop.
Replace defective parts, especially of
safety devices, only with genuine
replacement parts. Parts not tested
and approved by the manufacturer
can cause unforeseen damage.
After all servicing:
− Check to see that all safety
devices are operational.
− Make sure that no tools or other
parts remain on
machine.
Repair and maintenance work other
than described in this section should
only be carried out by qualified spe-
cialists.

Replacing Planer Knives

3
Note:
Dull planer knives are recogniza-
ble by:
− reduced planing performance;
− increased risk of kickback;
− motor overloads.
A
Danger!
Risk of personal injury by cuts from
the planer knives! Wear gloves when
changing planer knives.
To remove the planer knives:
1. Unplug power cable.
2. Remove jointer fence.
3. Raise cutterblock guard extrusion
fully and pull extrusion fully out-
wards.
4. Turn the four hexagon head screws
of the planer knife lockbar fully in
(wear gloves!).
69
5. Remove planer knife lockbar (70)
with planer knife (69) from the cut-
terblock (71).
6. Clean all surfaces of cutterblock and
planer knife lockbar.
A
Danger!
Do not use cleaning agents (e.g. to
remove resin residue) that could cor-
rode the light metal components; the
stability of the light metal compo-
nents would be adversely affected.
To install the planer knives:
3
Note:
If you use planer knives having
an edge on both sides you simply need
to reverse the knives, provided the other
edge is sufficiently sharp.
or in the
A
Danger!
− Use only suitable planer knives
(see "Technical Specications") –
unsuitable, incorrectly mounted,
dull or damaged planer knives
can work loose, or increase the
risk of kickback considerably.
− Always replace or reverse both
planer knives.
− Install planer knives using only
genuine replacement parts.
7. Place fresh planer knife on planer
knife lockbar as shown.
Both pins of the planer knife lockbar
must fit into the holes (72) of the
planer knife.
