attention and care. T erefore, for your own safety, pay attention to t e instructions summarized in t is c apter.
T e mac ine can only be used safely w en t e operator strictly follows t e operating and safety instructions. It is
essential to read t is manual before using t e mac ine to know ow t e mac ine functions and w at t e
limitations are.
- Provide for sufficient space around t e mac ine and a good lig ting of t e works op.
- W en c anging t e tools or performing a maintenance job, t e mac ine as to be disconnected from t e
power supply.
- Knives and tools w ic are not correctly s arpened or in a bad condition not only diminis t e quality of t e
work, but also increase t e risk of accidents.
- Always make sure t at all necessary safety are fitted to t e mac ine and t at t e mac ine is connected to a
dust extraction system.
- Always wear suitable clot ing. Loose or torn clot es are very dangerous w ile operating t e mac ine.
- Keep c ildren away from t e mac ine and t e works op.
- Wearing of earing protection is recommended to prevent noise from damaging your earing.
- W en cutting narrow pieces always use a pus stick. W en damaged replace t e pus stick at once.
- Always use jigs, templates and sawblades adapted to t e work carried out.
- Read t e recommendations to clean t e mac ine carefully. Clean only w en t e mac ine is disconnected from
t e power supply line.
- Make sure all periodic maintenance is done on time. T ese maintenances works s ould only be carried out
wit t e mac ine disconnected from t e main power supply line t us rendering it impossible to start t e
mac ine involuntary.
- Test on a weekly basis t e following electrical components: emergency stop buttons, t e safety switc es and
test if t e mac ine can be started up wit an open door.
- Test on a weekly basis if t e rundown time of t e motor brake does not exceed 10 seconds.
- Keep t is manual w ere t e operator may refer to w enever necessary. T is manual must accompany t e
mac ine w en it is sold, rented or lent to a t ird party.

User guide
T e following recommendations for safe working procedures are given as an example, on top of all information
and c aracteristics of t is mac ine.
- W en working wit t e mac ine, safety equipment must be used.
- Nevert eless, t e user must also follow t e operating instructions to avoid accidents.
Training of the machine operators
It is absolutely essential t at t e mac ine operator gets enoug training regarding operating and adjusting t e
mac ine. In particular:
- t e risks involved in working wit t e mac ine;
- t e operating principles, t e correct use and adjustments of t e mac ine;
- t e correct c oice of t e tool for eac operation;
- t e safe andling of t e parts to be processed;
- t e position of t e and in relation to t e turning parts;
- storing workpieces safely before and after mac ining t em.
Stability of the machine
In order to use t e mac ine safely, it is essential to place it stable on t e ground.
Adjustment and installation
- Disconnect t e mac ine from its power supply for eac adjustment.
- T e recommendations of t e manufacturer ave to be followed w en adjusting and installing t e tools.
- T e tools ave to be suited to t e mac ine in order to assure a safe and efficient usage.
- T e tools ave to be correctly s arpened and installed wit tool olders t at are carefully balanced.
Handling of tools
W en touc ing t e tool t ere is always t e danger to get urt by cutting edges.
- Be cautious w en unpacking or packing, as well as andling.
- Do not touc tools at t e cutting edges.
- Wear safety gloves w en andling tools in your works op.
- Always put t e tools on a soft support.
- Transport clamping adaptors and tools only in a suitable packing.
Machine handling
- C oose for eac action t e most appropriate safety devices.
- Do not remove c ippings, cuttings, dust and waste of wood or particle board by and.
Installing tools
Special equipment, suc as tool setting gauges, are to be used only w en t e mac ine isn't operating.
Table insert rings ave to be used in order to reduce t e space between t e table and t e spindle s aft to a
minimum.
Adjustment of the fences
Working wit t e spindle fences requires special attention:
- a false or integrated fence s ould be used to minimize t e opening between t e tools and t e fences
- a pus stick s ould be used as often as possible
- a wood pus er s ould be used, toget er wit protection, to pus t e piece manually
- long pieces need to be supported wit roller supports
Direction of rotation and choice of speed
It is very important t at t e c osen tool turns in t e rig t direction.
W en t e piece is presented, t e operator must take care t at t e work piece is fed in t e correct direction at
t e correct c osen speed. T e speed also as to be suited to t e tool on t e mac ine.
Functioning of the machine, choice of safety e uipment and adjustments
Because of t e various tasks t at are carried out by various spindle s afts, spindle olders and cutter blocks,
different types of safety equipment ave to be used. Every operation as to be examined separately and t e
appropriate guarding as to be c osen. T e minimal opening in t e table also depends on t e type of cutter
block, t e diameter of t e knives and t e eig t w ic t e cutter block is adjusted in. In t at way, t e opening is
as narrow as possible and t e work piece no longer can flip over and it t e knives.
Using a power feeder can prevent most serious accidents involving ands. Suc feeders easily are adjusted and
adapted to t e size of t e pieces.
W en no power feeder is used, t e wood pus ers ave to be used, t e orizontal and vertical springs making a
tunnel w ere t e piece can slide in. T is pus er, toget er wit ot er safety equipment, reduces t e gap between
4

t e cutting tool and t e guide fences.
Using the spindle fence when the total length of the machine has to be machined
In most cases a straig t guard fence is used. In t is way t e pieces can be guided in t e angle made by t e table
and t e fence. T e vertical and orizontal pus ers can be placed in suc a way t at a tunnel is formed in w ic
t e first piece can be pus ed. T e second piece is t en used to pus t e first, t e final piece as to be pus ed
forward wit a wood pus er.
Special blocks ave to be used relative to t e dimensions of t e work piece.
W en working t in panels, only t e top of t e spring as to be used, on condition t e t ickness matc es.
On a spindle-moulder, t e distance between t e extremities of t e spindle guard fences must be large enoug to
leave enoug space for t e cutter block. T us t e knives, t e cutter block and t e spindle s aft may be exposed
and t e extremity of t e piece may come in contact wit t e nose of t e exit guard fence.
T ese risks can be avoided by using a false fence between t e spindle guard fences, t us limiting t e opening
between t em.
Using the spindle guard fence when only a part of the piece is machined
W en using t e spindle fence between 2 stops fixed onto t e mac ine table or fences, only a part of t e work
piece is mac ined. By doing so, t e cutting tool starts mac ining t e work piece in t e full section of t e wood
and doesn't start at t e front, t is way t e cutting action is more gradual and less severe, and t e cutting action is
stopped before t e workpiece end is reac ed. T is action is very dangerous and needs special attention and care.
A stop solidly fixed at t e front and back as to be used (see t e example used furt er in t is manual).
A piece may only be guided by and w en it is sufficiently large. In all ot er cases a gauge or a support wit
protection as to be used in order to avoid serious accidents. By means of t e gauge, t e piece can quickly and
precisely be put in place and firmly be eld t ere. A quick clamping system, working wit tumblers or cams, is t e
most practical to old t e piece. W en front and backstops are fixed to t e spindle guard fence or to t e table, a
better control of t e gauge is possible.
Working with the ring guard
W en working wit t e ring guard, a support as to be used, unless a certain process doesn't allow t is, i.e.
w en t e work piece is too large or too small, or w en too difficult to mac ine it cannot be eld in t e support
wit out danger. T e final s ape is obtained by olding t e gauge against a guidance bearing w ic is fixed to t e
spindle w ile t e piece is eld against t e tool. T e gauge can be part of t e support.
Chamfering
W en c amfering a solid support or a tilt adjustable spindle, a guard fence as to be used. A wood-pus er as to
be used for t e final part of t e mac ining.
Working in the direction of the tools
It is extremely dangerous to work in t e direction of t e tools, as t e operator cannot exert force to resist t e
strong movement of t e piece w en t e tool comes into contact. Working in t e direction of t e tools is
forbidden, even w en a support is used.
Other machining
For ot er types of work, e.g. tenoning, special gauges or supports can be used in order to avoid accidents.
T e following safety accessories can be used to elp t e operator during is work:
- supports,
- wood pus ers,
- power feeders,
- rollers,
- stops.
Reasons for tool rupture
Following reasons may lead to a tool rupture:
- grinding cracks or a c ange of t e cutting geometry due to improper s arpening
- jerky movements of t e work piece
- jamming of tool by waste piece
- over eating by friction due to slow feed rate or too low cutting dept , as well as due to dull cutting edges
- too ig feed rate
- too large cutting dept
- insufficient clamping of t e tool
- vibration of t e mac ine.
Operation
- Danger of injuries or crus ing by t e rotating tool
- Do not touc t e rotating tool

- Do not slow dawn t e tool by lateral pressure against t e body
- Do not work wit out t e necessary safety guard
Operator’s place at the workpost
For all executions wit t e spindle fence, and for use of t e ring guard fence:
W en tenoning:
Normal and prohibited use
Wit t e T 120 spindle-moulder t e operator can mould and form straig t and curved pieces, and almost any
task in woodworking can be executed in massive wood, wood-based panels and certain plastics.
It is strictly forbidden to process ferrous and non-ferrous materials. It is also forbidden to make c anges to t e
mac ine in order to execute ot er tasks t an t ose described above.
Moulder-shaper
T e s aper assembly is assigned to t e following tasks and equipped wit protective devices. Ot er tasks t an
listed below are t erefore pro ibited.
NORMAL USE
- mould and form straig t and curved pieces on t e vertical spindle;
- s aping of curved work pieces using a ring guard fence;
- mortising, tenoning and panel edge s aping using corresponding safety devices.
PROHIBITED USE
T e following tasks are pro ibited on t e moulder-s aper unit:
- down-cut s aping, i.e. W en feed and tool rotation direction is t e same;
- slotting wit saw blades;
- using tool diameters t at are not adapted to t e spindle by using reducing sleeves;
- using larger tool diameters and ig er speeds t an s own in t e diameter-speed diagram;
- t e use of ferrous and non-ferrous.
REMAINING RISKS
Spindle s apers are one of t e main causes of injuries in woodworking. Nearly all accidents result in and injuries.
Due to contact wit t e rotating tool w en t e work piece is fed by and, a kickback occurs.
T e main danger areas on t e s aper-moulder are:
- t e moving mac ine and tool parts;
6

- t e kickback area.
Always use t e appropriate protection devices and observe t e specific regulations for accident prevention.
Despite t e use of specific protection devices and t e application of t e ygiene and safety instructions, some
risks remain w en working wit t e moulder-s aper:
- risk of accidents in t e insecure area of t e tools;
- risk of wounding w ile replacing tools;
- risk of wounding by t e piece of wood itself;
- crus ing of t e fingers;
- risk of jamming of t e and in t e mac ine, w en using a removable pus er;
- risk of back kicked pieces of wood;
- ealt risk t roug prolonged in alation of particles, especially oak, beac or exotic sorts of wood
- deafness t roug prolonged exposition to noise.
Acoustic levels
T e values given are t e output levels, t ese are not necessarily t e levels on w ic t e operator can work safely.

Ear protection is recommended.
Dust extraction
For your ealt and to avoid risk of fire and dust explosion, it is recommended to connect t e mac ine to a dust
extraction system.
A 120mm outlet is provided. It as to be connected to a dust extractor powerful enoug to obtain an airflow of
at least 20 m3/sec (at least 1500 m3/ ) measured at t e outlet of t e mac ine.
Types of tools
Cutter blocks and t e tool olders wit interc angeable blades are frequently used w en moulding.
T e cutter blocks can be made in one piece, t e cutting part being fitted in a body of ard steel, mostly
c romium steel. T e tool olders consist of t e part on w ic t e knives are fitted mec anically. T eir cutting
part is made out of ard metal (HSS) or calcium-carbide (K), as is t e case for t e cutter blocks.
Mortiser
Only use “left” drills on t e mortiser. To avoid vibrations, s ort drills s ould be used as often as possible.
IMPORTANT
For eac tool and for eac diameter, t e correct speed must be c osen.
ickback of the workpiece
Definition
A piece of wood can be rejected in t e direction of rotation of t e tool in a brutal and unexpected manner. T is
can appen w en only a part of t e wood is mac ined, w en feeding direction and rotation direction are
identical, and in several ot er cases.
Causes
T is problem is mainly due to t e design of t e tool body w ic , by its construction, enables t e operator to
take big passes. Ot er causes can also ave an influence:
- number of inserts on t e tool;
- cutting speed;
- inserts sticking out compared to tool body
- type of wood;
- adjustments (e.g. cutting dept ).
Independent of t e above mentioned, following factors ave to be taken in account:
- working conditions: starting to cut in t e middle of a piece of wood, mac ine running, working in t e same
direction as t e rotation sense of t e tool, working wit out stops fixed to t e table or spindle fences.
- speed not adapted to t e type and diameter of tool
7

- maintenance of t e tools: blunt tools, bad installing of t e knives on t e tool- older.
W en t e wood is rejected, it appens sudden and fiercely. A piece of wood wit a square of 50mm and a lengt
of 1 m can be rejected speed t at varies between 20 to 30 m/sec ( i.e. 70 tot 110 km/ ).In t e mentioned case
t e average speed of 100 km/ is already attained after +/- 30 t ousand of a second (0,030) after rejection.
Possible solutions
In all cases:
- use tool- olders; nowadays t ere is a new generation of cutting tools w ic is equipped wit a limited pass.
Alt oug t e rejection of a piece of wood is not ruled out completely, it is nevert eless easier to control by
t e operator.
- c eck w et er t e tools are correctly s arpened,
- respect t e speed of t e tools as to type and diameter. T e sticker on t e mac ine indicates t e optimal
speed to be c osen, taking into account t e type of tool and t e diameter.
- never exceed t e maximum speed t at is indicated on t e tool.
Last but not least: always install various protections w en working wit t e mac ine. T e vertical and orizontal
wood-pus ers must be adjusted so t at t ere is complete freedom of movement to put t e piece of wood into
place and to mac ine it wit out t e risk of ands coming in contact wit t e tool.
