5. Feed work piece slowly and straight into the
thicknesser. It will then be automatically fed
through the thicknesser.
6. Guide work piece straight through the thick-
nesser.
7. Switch machine off if no further thicknessing is
to be done immediately afterwards.
10.3 Use a suitable extraction system
Danger!
Some types of wood dust (e.g. from oak and
ash wood) can cause cancer when inhaled: In
closed rooms work only with a suitable chip
extraction system.
– Fitting the outer diameter of the suction port
(100 mm);
3
– Air volume ³ 550 m /h;
– Vacuum at suction port of thicknesser
³ 740 Pa;
– Air speed at suction port of thicknesser
³ 20 m/s.
Caution!
Operation without a dust collector is only
possible:
– outdoors;
– if only a minimum of chips is generated
(with narrow stock and little chip removal);
– with dust respirator.
11. Care and Maintenance
Danger!
Prior to all servicing:
– Switch off the machine.
– 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 manu-
facturer can cause unforeseen damage.
After all servicing:
– Put back into operation and check all safety
installations.
– Make sure that no tools or other parts
remain on or in the machine.
Repair and maintenance work other than
described in this section should only be
carried out by qualified specialists.
11.1 Replacing Planer Knives
Note:
Blunt planer knives are recognizable by:
– reduced planing performance;
– increased risk of kickback;
– motor overloads.
Note:
The supplied planer knives are sharp-
ened on both sides and cannot be resharp-
ened. Reverse blunt planer knives. If both
sides are worn, the planer knife must be
replaced, see chapter Accessories.
Note:
Follow the manufacturer's instructions
for the replacement planer knives. Have a
specialist carry out the resharpening of planer
knives intended to be resharpened.
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 fence (6).
3. To gain access to the cutterblock: Move the
cutterblock guard extrusion (22) all the way up
and out.
See fig. T.
4. Insert the four hexagon head screws of the
planer knife lockbar (a) completely (wear
gloves!).
5. Remove planer knife lockbar (a) with planer
knife (b) from the cutterblock (7).
6. Clean all surfaces of cutterblock and planer
knife lockbar.
Danger!
Do not use cleaning agents (e.g. to remove
resin residue) that could corrode the light
metal components; the stability of the light
metal components would be adversely
affected.
To install the planer knives:
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.
Danger!
– Use only suitable planer knives (see "Tech-
nical Specifications", chapter "Accesso-
ries") – 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. See fig. U: Place the sharp planer knife (b) as
shown on the planer knife lockbar (a).
Both pins of the planer knife lockbar must fit into
the two holes (c) of the planer knife (b).
8. Place the planer knife lockbar (a) with he planer
knife (b) into the cutterblock (7). Ensure that the
planer knife does not slip off the pins of the
planer knife lockbar.
9. See fig. V: Unscrew the four hexagon head
screws from the planer knife lockbar (a), until
the lockbar (a) and planer knife (b) can still just
be moved along the axis of the cutterblock.
10.There are two ways to check the projection of
the knives:
- Option 1: See fig. W: Place the setting
gauge (d) (supplied) as shown on the cutter-
block (7). The planer knives (b) must project so
much that they touch the setting gauge.
This check must be performed on both planer
knives and at both ends of the cutterblock.
- Option 2: See fig. X: Using an aluminium
straight-edge (e) (this is more accurate than
using the setting gauge (d)).
- Place the aluminium straight-edge (e) as
shown over outfeed table (1) and cutterblock
(7).
- Turn cutterblock by hand one turn against the
direction of feed.
- The planer knives are set correctly if the
straight edge is moved forward 4 to 6 mm by
the turning cutterblock.
This check must be performed at both ends of
the cutterblock.
11.To set the knife projection, turn the grub screws
in the planer knife lockbar with a 3 mm Allen
key as required.
12.See fig. Y: To tighten, unscrew the four
hexagon head screws completely from the
planer knife lockbar. To prevent distortion of the
planer knife lockbar start with the screws in the
centre, then tighten the screws closer to the
edges.
Danger!
– Do not extend tool when tightening the
screws.
– Do not tighten bolts by striking the wrench.
13.Return cutterblock guard extrusion (22) to its
starting position.
14.Replace the fence (6).
11.2 Feedgear Maintenance
(on the side of the fence (6)).
1. Unplug power cable;
2. Unscrew the two nuts of the drive cover and
remove the drive cover.
3. Remove chips and dust with dust collector or
brush.
4. See fig. Z: Apply a light coat of care and main-
tenance spray to roller chain and shaft and axle
bearings (do not use oil!).
5. Replace the drive cover and secure with the
two nuts.
11.3 Main Drive Belt Tensioning
(on the side of the on/off switch (20)).
See fig. AA:
1. Unplug power cable;
2. Unscrew the nut of drive belt cover and remove
cover (a).
3. Check belt tension with thumb pressure. The
drive belt (b) should not give more than 10 mm
in the centre.
If the drive belt requires tensioning:
4. Loosen the four motor mounting screws (c) by
approx. one turn.
5. Push motor down to tension belt.
6. When belt tension is correct tighten motor
mounting screws (c) crosswise.
7. If necessary, remove chips and dust with dust
collector or brush.
8. Put belt cover back on and secure with nut.
11.4 Machine Cleaning and Care
1. Unplug power cable;
2. Remove chips and dust with dust collector or
brush from
- cutterblock;
- height-setting mechanism of cutterblock guard
extrusion;
- thicknesser bed spindles;
- thicknesser feed drive.
3. Apply a light coat of care and maintenance
spray to the following components (do not use
oil!):
- thicknesser bed spindles;
- height-setting mechanism of cutterblock guard
extrusion.
4. Apply a light coat of anti-seize compound to
infeed table, outfeed table and thicknesser
bed.
11.5 Transporting the Machine
Caution!
Do not carry from the infeed or outfeed table!
The machine can be transported by one person.
Tilt the machine at the transport handles (16) until
the machine stands on the transport wheels (19)
and move it on the transport wheels.
11.6 Machine storage
Danger!
1. Unplug power cable;
2. Store machine in such manner that
- it cannot be used or tampered with by
unauthorized persons, and
- that nobody can get hurt while the
machine is turned off.
Caution!
Do not store machine unprotected outdoors
or in damp environment.
11.7 Maintenance Table
The checks and procedures described in this
section are an aid to safety! Should there be faults
evident on any of the mentioned components, the
machine must not be used until these faults have
been remedied in a workmanlike manner.
