1.3 — Electrical equipment according to
European Standard “CENELEC EN 60 204-1”
which assimilates, with some integrating
modifications, the publication “IEC 204-1
(1992)”
•The electrical equipment ensures protection against electric
shock as a result of direct or indirect contact. The active
parts of this equipment are housed in a box to which access
is limited by screws that can only be removed with a special
tool; the parts are fed with alternating current at low voltage
(24 V). The equipment is protected against splashes of water and dirt.
•Protection of the system against short circuits is ensured by
means of fuses and grounding; in the event of motor overload, protection is provided by a thermal probe.
•In the event of a power cut, the specific start-up button must
be reset.
•The machine has been tested in conformity with point 20 of
EN 60204.
1.4 — Emergencies according to European
Standard “CENELEC EN 60 204-1 (1992)”
•In the event of incorrect operation or of danger conditions,
the machine may be stopped immediately by pressing the
red mushroom button.
NOTE:Resetting of machine operation after each emergency
stop is achieved by reactivating the specific restart
button.

•To obtain break-in of the machine it is advisable to start using it at intervals of about half an hour. This operation should
be repeated two or three times, after which the machine
may be used continuously.
•Before starting each cutting operation, ensure that the part
is firmly gripped in the vice and that the end is suitably supported.
•Do not use blades of a different size from those stated in the
machine specifications.
•If the blade jams in the tube, release the running button
immediately, switch off the machine, open the vice slowly,
remove the part and check that the blade or its teeth are not
broken. If they are broken, change the blade.
•Before carrying out any repairs on the machine, consult the
dealer or call Parker Tube Fittings Division.

First of all, the pitch of the teeth must be chosen, according to
these criteria:
• Parts with a thin and/or variable section such as profiles,
pipes and plate, need close teeth, so that the number of
teeth used simultaneously in cutting is from 3 to 6;
• Parts with large transverse sections and solid sections need
widely spaced teeth to allow for the greater volume of the
shavings and better tooth penetration;
• Parts made of soft material or plastic (light alloys, mild bronze,
teflon, wood, etc.) also require widely spaced teeth.
9.3 — Teeth pitch
As already stated, this depends on the following factors:
• Hardness of the material
• Dimensions of the section
• Thickness of the wall

9.6 — Type of blades
Blades differ in their constructive characteristics, such as:
• Tooth shape
• Tooth cutting angle
Tooth shape
The profile of the teeth depends on the size, shape and thickness of the section to be cut, either straight or at an angle. It
may also vary according to the pitch, but not so distinctly as to
make this an element for classification.
• Fine teeth are to be chosen for cutting small sections with a
profiled shape and tubular sections with thin walls (2-5 mm
depending on the material).
• Large teeth are suitable for cutting medium and large solid
sections or fairly thick profiled or tubular sections (over 5
mm).

9.4 — Cutting and advance speed
The cutting speed (m/min) and the advance speed (cm2/min =
area travelled b y the b lade teeth when remo ving shavings) are
limited by the heat build up at the tips of the teeth.
• The cutting speed is subordinate to the resistance of the
material (R = N/mm

the blade to deviate from the ideal cutting path, producing
