ches in order to be able to switch on the planer-thic-
knesser in a way other than intended.

Safety
ADH-Series | Version 1.02 7
Danger due to insecure position.
For long workpieces, use suitable workpiece supports
on both sides of the planer-thicknesser. Avoid an unfa-
vorable posture. Make sure that you stand securely.
Keep the working area clean.
Danger to other persons in the working area
Keep the unauthorised persons, especially children,
away from the danger area. Point out the hazards of the
planer-thicknesser to persons who will help you when
working on the planer-thicknesser.
Danger from touching the rotating cutter head
Always keep sufficient distance to the cutter head.
Switch off the planer-thicknesser when it is not in use.
Risk of the workpiece hitting back
The workpiece is picked up by the cutter head and
thrown against the operator. Work only with the non-re-
turn device functioning correctly. Only use sharp pla-
ning knives. Check the workpiece for foreign objects be-
fore starting work.
Consider work area’s environment
Do not expose tools to rain. Do not use tools in damp or-
wet location. Keep work area well lighted. Do not use
tools in the presence of flammable liquids or gases.
Keep the unauthorised persons, especially children,
away from the danger area. Point out the hazards of the
planer-thicknesser to persons who will help you when
working on the planer-thicknesser.
Risk due to defects in the planer-thicknesser
Before each use, check the planer-thicknesser for da-
mage or dismantled, defective protective covers and
protective devices. Do not use the planer-thicknesser if
a part is defective. Replace the blunt planing knives im-
mediately. There is a risk of kickback if a blunt planing
knife gets caught in the surface of the workpiece.
Danger of overloading the planer-thicknesser
Only operate the planer-thicknesser in the specified po-
wer range. Use the planer only for the purpose for which
it is intended.
Before each switch-on, make sure that there are no objects such
as tools in the planer-thicknesser.
2.7 Safety equipment
Undervoltage release
In the event of an electrical power failure, an undervol-
tage relay is triggered. This prevents the planer-thick-
nesser from starting up again on its own as soon as
electrical voltage is present again. To reset the ma-
chine, it must be restarted.
Overload protection
The planer-thicknesser has a built-in overload protec-
tion. The overload protection switches off the planer-
thicknesser if the motor has become too hot. To switch
the planer-thicknesser on again:
- Let the motor cool down for about ten minutes.
- Switch the machine on again
Automatically switch-off by opening
A microswitch switches off the machine when the table
is opened.
A microswitch switches the machine off when the chip
catcher is opened in the "Thickness planing" mode.
The machine cannot start if the tables of the dressing
machine and the chip catcher are not closed during
operation of the planer.
Chip catcher
The chip catcher covers the cutter head when opera-
ting as a thicknesser and prevents access to the cutter
head below the tables when operating as a planer de-
vice. The chip catcher can be fixed in both positions -
for the planer device and for the thickness device.
Separator devices
Separator devices between the cutter head and the
feed roller (or discharge roller) are used to avoid contact
and access to the cutter shaft underneath the tables of
the planer
Motor brake
Electronic brake for electrodynamic braking of motors.
Ensures tool braking in less than 10 seconds after motor
switch-off.
ENTANGLEMENT HAZARD!
Ensure that no parts of the body or clothing can be
caught by the machine and pulled in during opera-
tion. Wear tight-fitting clothing and if necessary a
hair net.
Protective gloves
Use protective gloves when changing the planing
knife.

Step 1: Loosen the lock knob (Pos. J, Fig. 10), slide the
guard into position, then tighten the lock knob.
Step 2: To slide fence forward or backward:
When edge jointing, the fence assembly should
nperiodically be moved to different positions to
distribute wear on the cutter head knives. This is
done as follows:
NOTE!
A depth of cut of 1.5mm or less is recommended.

Operation
ADH-Series | Version 1.02 17
Step 2.1: If necessary, loosen the cutter head guard
(Pos. H, Fig. 10) to permit the fence assembly
to move freely without being constrained by
the guard.
Step 2.2: Loosen two fence assembly locking handles
(Pos. E, Fig. 10).
Step 2.3: Move the entire fence assembly to the desired
position; then re-tighten the handles (Pos. E,
Fig. 10).
Step 2.4: Readjust and secure the cutter head guard.
Tilt the fence backward.
Step 2.5: The fence (Pos. A, Fig. 10) can be tilted back-
ward (Pos. D, Fig. 10) up to 45°(that is, for a to-
tal included angle of 135° from table surface)
as follows:
a) Loosen locking handles (Pos. F, Fig. 10).
b) Tilt the fence back (Pos. A & Pos. C, Fig. 10)
to the desired angle up to 135 degrees.
c) Tighten the locking handles (Pos. F, Fig.10).
d) Readjust and secure the cutter head guard.
8.2 Adjustments
8.2.1 Table and knife adjustments
For accurate jointing, at least three things must be true:
- Infeed and outfeed tables must be coplanar.
- Knives or knife inserts must be set in the cutter head
so that the highest point of their arc is level with the
outfeed table.
- On the standard cutter head, knives must be paral-
lel with the outfeed table across the entire length of
the knives.
Fig. 11: Table setting
These alignments are explained below:
Coplanar Alignment
Definition of coplanar
When the infeed table is set to the same level as the out-
feed table and together both tables form a "perfect" flat
surface, the tables are said to be coplanar.
For optimum performance of the jointer, the infeed and
outfeed tables must be coplanar. If they are not, the fi-
nished workpiece may have a slight taper or twist
across jointed its width or length.
The tables have been set coplanar at the factory, but
they should be double-checked by the operator.
Also, as the machine undergoes use, the tables should
be checked occasionally and adjusted if necessary.
The procedure described below uses a steel straight
edge to set the tables, which should be accurate
enough for most purposes.
Important: The tables must be locked in position when
performing the following test:
Step 1: Disconnect the thicknesser from power source.
Step 2: Loosen the lock knob (Pos. A, Fig. 11) and slide
the cutter head guard (Pos. B & Pos. C) to clear
the table.
Step 3: Slide the fence assembly back (Pos. H & Pos. E,
Fig. 11) as far as it will go, or remove it from the
machine entirely.
Step 4: Rotate the cutter head to avoid knife interference.
Step 5: Place a straight edge (Pos. D, Fig. 11) across the
front of the outfeed table (Pos. F, Fig. 11) and ex-
tending over the infeed table (Pos. G, Fig. 11).
Note the position of the infeed table (Pos. G, Fig.
11). Note the position of the straight edge in Fi-
gure 9 with respect to the fence (Pos. H, Fig. 11).
Step 6: Raise the infeed table (Pos. G, Fig. 11) until it
contacts the straight edge (Pos. D, Fig. 11). The
straight edge should be straight and level over
both tables.
Tips and recomendations
You can use a reference piece or a measuring
instrument to facilitate the alignment of the stop.
ATTENTION!
The machine must be switched off at the ON/OFF
switch before switching from planer to thickness ope-
ration.

18 ADH-Series | Version 1.02
Operation
Fig. 12: Table setting
Step 7: Move the straight edge to the back of the output
table as shown in Fig.12 and perform the test
for this as well.
If the straight edge is not level, the front or rear table
must be adjusted to make the tables coplanar. If align-
ment is required as described in the previous section,
proceed as follows:
Disconnect the device from the power source before
making any adjustments. Failure to do so may result in
serious injury.
Step 1: Disconnect power from machine.
Step 2: Unlock both cabinet lock handles (Pos. A2,
Fig. 13).
Step 3: Raise the table (D) fully upright. Adjustment is
performed by means of four setscrews (Pos. B2,
Fig. 13) that adjusts the table pitch and tilt at the
back (towards the fence) and two hex cap
screws (Pos. A1, Fig. 13) that adjusts the table
toward the front.
Adjustment can consist of a front adjustment, rear adju-
stment or (more probable) a combination of both.
Adjustment of the rear area:
Required tools:
- 13 mm. wrench
- 4 mm. hex wrench
Step 1: With a 13mm wrench, loosen three hex cap
screws (B1).
Step 2: Using a 4mm hex wrench, make very slight adjust-
ments of 1/8 to 1/4 turns to four setscrews (B2) as
required.
- A clockwise turn will raise the table;
- A counterclockwise turn will lower the table;
- Adjusting the two right setscrews will have greatest
adjustment impact to the table's right side;
- Adjusting the two left setscrews will have greatest
adjustment impact to the table's left side.
Fig. 13: Adjustment of rear and front area
Step 3: When adjustment is complete, tighten the hex cap
screws (Pos. B1, Fig. 13).

Operation
ADH-Series | Version 1.02 19
Adjustment of the front area:
Required tools:
- 2 x 13 mm. wrench
Step 1: Hold the hex cap screws (A1, Fig. 13) in place
with one wrench while using the other to loosen
the locking hex nuts.
Step 2: Adjust the screws (Pos. A1, Fig. 13) slightly from
1/8 to 1/4 turn.
Step 3: Loosen the three hex head screws (Pos. B1,
Fig. 13) with a 13 mm socket wrench:
- A counterclockwise turn willraise the table;
- A clockwise turn will lower the table.
- Adjusting the right screw will have greatest adjust-
ment impact to the table's right side;
- Adjusting the left screws will have greatest adjust-
ment impact to the table's left side.
Step 4: When adjustment is complete, secure by tigh-
tening the hex nut while maintaining the position
of the screw with the second wrench.
It may be necessary to repeat the exercise in this
section more than once to achieve coplanar align-
ment.
8.2.2 Setting cutter head knives
Step 1: Disconnect machine from the power source.
Step 2: Remove the cutter head guard (Pos. B, Fig. 11).
Step 3: Carefully number each knife blade (Pos. C, Fig.
14 and Fig. 15) with a magic marker to differen-
tiate each.
Step 4: Rotate the cutter head (Pos. E, Fig. 14 and
Fig. 15) and determine the 12 o'clock position of
knife number one.
The 12 o'clock position is the highest point a
blade will reach in the cutting arc (Pos. C,
Fig. 15).
Fig. 14: Cutter head
Step 5: Set a straightedge (Pos. J, Fig. 14) on the out-
feed table (Pos. F, Fig. 14) near the fence
(Pos. H, Fig. 14).
- One end of the straightedge should be positioned
over the cutting knife (C) near the end of the blade
as shown in Fig. 12.
- Use care when handling the straight edge near the
blades to prevent damage.
NOTE!
If the table does not lock properly after adjustment,
the thicknesser table lock lever must be adjusted.
NOTE!
Before performing any adjustments in this section,
the infeed and outfeed tables must be coplanar.
DANGER!
Cutter head knives are dangerously sharp! Use
extreme caution when inspecting, removing, shar-
pening or replacing knives into the cutter head. Fai-
lure to comply may cause serious injury
NOTE!
To rotate the cutter head the cutter head pulley
must be turned. This requires removing the panel on
the back of the cabinet for access.

20 ADH-Series | Version 1.02
Operation
Fig. 15: Cutter head cross-section
Step 6: Note the position of the knife blade with respect
to the straight edge, then move the straight
edge to the other side of the table and again
note the position of the knife blade with respect
to the straight edge. Blade number one must be
at the same height at each end and must also
be at the same height as the outfeed table (bot-
tom of straight edge). If this is not the case, ad-
justment is required as follows:
Step 6.1: Slightly loosen five gib lock screws (Pos. A,
Fig. 14) by turning into the lock bar (Pos. B,
Fig. 14), clockwise as viewed from the infeed
table (Pos. G, Fig. 14).
Step 7: Adjust the knife height by turning jack screws
(Pos. D, Fig. 14) upon which the knives rest. To
lower the knife, turn the screw clockwise. To
raise, turn the screw counterclockwise.
Step 8: When the knife is at the proper height, alterna-
tely tighten the five gib lock screws (Pos. A,
Fig. 14).
Step 9: Repeat steps 4 – 8 for knives two and three.

8.2.3 Replacement of cutting knives
Disconnect machine from power source before making
any adjustments. Failure to comply may cause serious
injury.
Step 1: Disconnect machine from the power source.
Step 2: Remove the cutter head guard (Pos. B, Fig. 9).
Step 3: Turn all five screws (Pos. A, Fig. 14 and Fig. 15)
into the lock bar (Pos. B, Fig. 14 and Fig. 15) by
turning in a clockwise direction as viewed from
the infeed table (Pos. G, Fig. 14 and Fig. 15).
Step 4: Carefully remove the cutter knife (Pos. C, Fig. 14
and Fig. 15) and lock bar (Pos. B, Fig. 14 and
Fig. 15).
Step 5: Repeat for remaining two knives.
Step 6: Thoroughly clean all surfaces of the cutter head,
knife slots and lock bars of any dust or debris.
Step 7: Insert replacement knife (Pos. C, Fig. 15) into the
knife slot, making sure it faces the proper direction.
Step 8: Insert lock bar (Pos. B, Fig. 15) and tighten just
enough to hold in place.
Step 9: Repeat steps for other two knives.
ATTENTION!
- For workpieces with different thicknesses, first ma-
chine the stronger side (risk of wedging).
- Divide greater material removal into individual in-
feed steps.
- If wedging occurs, reduce infeed.
- Clean the worktable regularly.
- Make sure that the workpieces are free of resin or
dirt.
- Do not treat the worktable with lubricating oil or
grease.
- Use roller supports or extensions for long work-
pieces.
- Always machine workpieces to their full length.
- Do not machine bent or deformed workpieces.
