SAFETY
The following is a list of safety precautions you must consider when using a Thicknesser:
! ALWAYS REMEMBER TO DISCONNECT THE POWER TO THE THICKNESSER WHEN
MAKING REPAIRS OR ADJUSTING BLADES AND GUARDS.
! ALWAYS REMEMBER TO READ THROUGH THE MACHINE INSTRUCTIONS SUPPLIED.
• Eye protection, ear protection, respiratory protection
and chip extraction are highly recommended when
operating this machine.
• Do not wear gloves, loose clothing, jewellery, or any
dangling objects when operating a Thicknesser and
ensure that long hair is tied up out of the way.
• All guards must be in place and fully operational. If a
guard seems to be missing or damaged, adjust, replace
or repair immediately.
• Ensure that all visible electrical components (cables,
switches) are in good condition without damage.
• Hands and fingers must be kept clear of the blades,
• Use only the recommended blade size & type.
• Ensure all blades are sharp & in good condition.
• The blades must be adjusted in accordance with the
instruction manual.
• Never thickness plane small pieces – 12” in length
minimum.
• Long material should be supported at the same
height as the thicknesser table
• Ensure you are comfortable before you start
work,balanced, not over reaching.
• Do not use the machine if you are under the
influence of drugs or alcohol, tired or distracted.
• Do not allow children to operate the machine.
• Do not use the machine in an excessively damp or
wet environment.
• Never leave the machine unattended when it is
running.
• Keep the table top & surrounding work area free
from excessive dust & debris to help prevent slipping
or tripping.
• Ensure that the machine is stable on the floor, fixed
to the bench and wheel bases if used are locked off.

ASSEMBLY
Fig 01-02
A
1. Place the thcknesser (A) on a flat and lever surface and
fold both front & rear extention tables down, see fig 01-02.
Fig 03
5. Find the dust extraction hood. Slide the extractor (C)
into the space that occupied the cutter block housing
see fig 06. Gently push home until the extractor inlet
slots over the motor’s fan outlet, see fig 07. Secure in
place using the two Cap screws on either side of the
extractor moulding, see fig 08.

2. Remove all accessories parts from inside the machine,
see fig 03.
3. Locate the rise and full handwheel knob and caphead
screw (B). Rotate the rise & full wheel to the side of the
thicknesser until the threaded hole in the wheel is in
line with the elongated slot in the frame.
4. Inset the knob (B) into the holes recess in the wheel
assembly, introduce the Cap screw through the
elongated slot from inside the machine and secure
th
e knob in place using the supplied 4mm Hex key,
see fig 04-05.

NOTE: Dust and debris moving inside the plastic extraction hose may cause a build up of static electricity.
This can cause a potential hazard especially with fine
dust. The extraction outlet incorporates a ‘Anti-Static’
discharge cable. Secure the connector to the frame
using the power cable P-Clip, see fig 08.

7. Unlock the cutter block head unit by rotating the
locking lever to the left, Note: this is located above
the rise and full handwheel, see fig 09-10.

8. Turn the rise and full wheel clockwise to raise the
head sufficiently to remove the polystyrene blocks,
see fig 11-12.

8 Pre-Set Depth Stop
Save time on setup with 8 preset depth stops at the following
common timber thicknesses:
3.2mm, 6.35mm, 12.7mm, 19mm,
25.4mm, 31.75mm, 38mm and
44.5mm

SET UP
Levelling the Tables
For storage & transportation the infeed & outfeed support
tables are folded in the up position, for use these tables
will need to be folded down, see fig 13.
Fig 13
Before use the table will need to be levelled with the main
planer table.
1. Ensure that the planer is disconnected from
its power source
2. Fold both tables down.
3. Place a straight edge / clean spirit level through
the planer & rest it on the tables, see fig 14
Fig 15
Fig 16
Fig 17
4. Check to see if there are any large gaps underneath
the straight edge, see fig 15
5. To reduce the gaps & align the tables first lift the
tables & release the lock nuts, see fig 16
6. Adjust the stop screw until the folded support table
appears level with the main planer table,repeat both
sides for both the infeed & out feed tables, see fig 17-18
Fig 14
Fig 18
Ensure that the tables are
cleaned and waxed ready
for the first use

SET UP
Setting the Timber Thickness Scale
1. Using a scrap fairly flat piece of timber, measure the
thickness of the timber at each corner, see fig 19
2. Ensure that the cutter head is unlocked, then adjust
the cutter head height to match your timber
measurement then relock the cutter head, see fig 20.
3. Switch ‘ON’ the thicknesser and wait until it
reaches full speed.
4. Feed a piece of timber through as per operation
instruction on page 9, see fig 21.
5. Switch ‘OFF’ and wait until it comes to a complete stop.
6. Compare the measurement on the timber with the
reading on the scale, see fig 22.
7. If the reading is different, adjust the scales pointer by
loosening the two screws & moving the scale, see fig 23.

Securing to the Workbench
It is recommended to secure the planer to the workbench
when in use, for this we suggest mounting your planer to
a baseboard, see fig 24.
Fig 24
1. Choose a board around 50% larger than the planers
footprint / base size & at least 16mm thick.
2. Position the planer central to the baseboard & mark
the four mounting holes in the planer base, see fig 25.
3. Drill the four holes to suit the bolts using ( 70mm x
M8 recommended), to ensure that the board sits flat &
stable on the workbench or trestles counter bore the
holes slightly from the underside, see fig 26.
4. Fix the planer to the baseboard , bolting from
the underside, see fig 27.
5. Then simply clamp the baseboard & planer to the
workbench or trestle, see fig 28.

Before using the machine you must ensure that the
machine has been set up with the tables levelled & the
scale set. Also ensure that the tables are clean, waxed
and the extractor has been connected.
For the best results it is advisable to have the flattest side
of the timber facing down on the table. If a satisfactory
“flat” side cannot be found then it may be wise to flatten
off one side with either a surface planer or hand plane.
If the timber seems to be crowned then feed the timber
through crown up, see fig 29.
Fig 29
OPERATION
Fig 30
2. Set the thicknesser cutter head to this dimension using
the depth scale on the side of the machine and lock it off,
see fig 31.
Fig 31
1. Measure the largest/thickest section of the timber,
check this at all four corners of the timber, see fig 30.

OPERATION
3. Press the green “on” button & wait for the machine
to come up to full speed.
4. Place the timber on the infeed table & slowly advance
the timber towards the cutter head, see fig 32.
5. The depth of cut scale will give you an indication of
how much material will be removed, see fig 33.
6. Allow the machine to pick up the timber & pull it
through the cutter head, ensure that long lengths
of timber are supported, see fig 34.
7. Move to the rear of the machine to support the timber
as it is fed through the cut, do not pull it through, allow
the feed rollers to feed the timber through, see fig 35.
8. The first pass will only very lightly contact the timber,
to remove more timber & completely it clean up then
simply wind the head down, see fig 36.
9. Once the first side is clean & planed then flip the
timber over to plane the other side taking it down
incrementally down to your desired width.
Fig 34
Fig 35
10. It is perfectly ok to thickness the narrow edge of
the timber, a minimum of 20mm is recommended,
see fig 37.

IT IS IMPORTANT NOT TO OVERLOAD THE
PLANER, FOR HARDWOODS & WIDE TIMBER
BOARDS 150MM+ IT IS RECOMMENDED TO
REDUCE THE DEPTH CUT FOR EACH PASS
DOWN TO 0.5MM 1MM.

BLADE ROTATIONCHANGE
There are 26 HSS square cutters in total each with 2 cutter
edges across the 330mm cutting width, after many hours
of use these cutters will need rotating or replacing
DISCONNECT THE MACHINE FROM THE
MAINS SUPPLY BEFORE CONTINUING!
1. Undo the 2 cap screws and remove the plastic
extraction chute, see fig 38.
2. Brush all debris from the cutter/cutters that are to
be rotated or changed, see fig 39.
3. Using only the tool provided undo the countersink
Torx screw, see fig 40.
4. Lift & twist the cutter so that the fresh sharp edge faces
downwards, ensuring that there is no debris under the
cutter & the cutter is seated correctly, see fig 41.
5. Retighten the countersink Torx screw & repeat if
numerous cutters seem blunt or damaged, see fig 42.
6. NB - Each cutter has a rotation marker to help you
monitor which edges have been used - NB the cutting
edge & marker will always face down, see fig 43.
