ting pneumatic and hydraulic hoses up to a specific permissible dia-
meter, see “Technical Data” in Section 3.
Intended purposes include:
•Single user workplace for one person only
•Manual input and retrieval
•Operating temperatures between 5 °C and 40 °C
•Operation in a closed operation room
•The machine must not be operated by persons not capable of
operating the machine without any risk. These may include:
➢persons with physical or mental disabilities;
➢children and persons under age;
HAZARD!
WARNING!
CAUTION!
ATTENTION!

➢persons with a restricted capability for the operation of ma-
chines (e.g. under the influence of drugs, alcohol or narcot-
ics)
Use of the control in compliance with the intended purpose also inclu-
des compliance with the instructions in this Operation Manual.
Use for other than the intended purpose
Any other use is considered as being not in compliance with the in-
tended purpose, in particular:
•Design modifications of the machine
•Use in explosive environments
•Use of impermissible cutting knives
•Cutting of inflexible workpieces
•misuse of consumables and waste materials.
WARNING!
Risk for life and health!
Use not in compliance with the intended purpose imposes risks
for life and health. Consequences resulting from use for other
than the intended purpose shall be under the sole responsibility
of the owner.
•Always use the machine in compliance with its intended pur-
pose.
2.3 Product-specific risks
The machine/unit is designed in accordance with the latest state of
technology. Nevertheless, the machine/unit may impose risks:
2.3.1 Risks imposed by mechanical equipment
Cutting risk
A cutting risk exists during cutting and when the cutting knives are re-
placed.
•Take care and wear cut-proof protective gloves when cutting
and replacing knives.

Risk of squeezing
There is a risk of squeezing on the moving parts.
Tilting hazard
The risk of tilting mainly exists while the machine is being trans-
ported.
•Observe the machine's centre of gravity during transport.
2.3.2 Risks imposed by electricity
There is a risk of electrocution near the live parts!
•Work on electric systems may only be performed by qualified
electricians or instructed and trained persons under the supervi-
sion of a qualified electrician.
•Deactivate the machine/unit and secure it against unintentional
restart before maintenance.
2.3.3 Risk imposed by pneumatic system
Risks are imposed by all pneumatic lines and connections. Pneu-
matic systems are subject to special safety provisions.
•After the machine is deactivated, the given and potentially haz-
ardous residual energy has to be considered.
•Use correct hoses and hose clamps.
•Only work in the permissible pressure range.
2.3.4 Risks imposed by noise
The noise level meter acc. to IEC 804, Class 2, was calibrated before
measuring.
The operation of the machine causes noise emissions of 90 dB(A) at
the workplace. Noise protection is required.
Higher noise emissions may occur when other machinery is simulta-
neously used at the workplace. The machine owner must provide for
appropriate protection, e.g.
•instruct staff to wear ear protection;

•provide information/instructions on risks
•identify hazardous areas
•provide health monitoring
2.3.5 Risks in case of fire
The operating staff has to be familiar with the location as well as with
operating the fire alarm and fighting means. Free access to this
equipment must be ensured.
Use extinguishing powder in case of fire.
2.4 Safety
2.4.1 Working area
The working area is defined as the area all around the machine
(shaded).
•Keep the working area free from trip hazards.
•Use ducts for lines and cables.
•Provide good illumination.

2.4.2 Emergency-stop
The machine is fitted with an emergency-stop button.
Immediately activate the emergency-stop function (1) in cases of
emergency.
Remedy the cause of the emergency stop first before re-starting the
machine.

2.4.3 Warning signs on the machine
Cutting risk
on the cutting knife
Hand injury
on the cover
Danger from electric current
at the power supply line
Risk of eye injuries
Wear safety goggles

Risk of hearing damage
Wear ear protection
Illegible or missing warning signs must immediately be replaced by
the operator.

3.1 Design and function
(1) Bending pin
(2) Protective cover
(3) Strap grip
(4) Machine cover
(5) Compressed air maintenance unit
(6) Foot pedal
(7) Motor
(8) Cutting plate
(9) Main switch
(10) Control valve for feed speed
(11) Knife protection
(12) Hose feed

(13) Return stroke setting
The machine requires an electrical connection and a compressed air
connection. The pressure of the compressed air can be adjusted at
the compressed air maintenance unit (5).
The bending pins (1) prevent the cutting knife from getting jammed by
the work piece and enhance the cutting performance. Once the bend-
ing pins (1) are positioned according to the hose diameter, the work
piece is placed onto the cutting plate (8) between the bending pins (1)
and hose feed (12). The knife protection (11) prevents the operator
from unintentionally reaching into the cutting knife.
Once the protective cover (2) is closed, the machine is switched on at
the main switch (9), which starts the motor (7) and drives the cutting
knife. To perform the cutting procedure, the foot pedal (6) is pressed,
which moves the work piece towards the cutting knife via the pneu-
matically driven hose feed (12). When the foot pedal (6) is released,
the hose feed (12) moves back into the starting position.
The control valve for feed speed (10) can be used to adjust the feed
speed gradually according to the respective work pieces. The se-
lected speed depends on the hose design.
The return stroke setting (13) can be used to gradually adjust the dis-
tance the hose feed (12) moves back towards the starting position. In
this way, the return stroke path can be adjusted according to the re-
spective diameter of the work piece.

The machine may be fitted with accessories. A list of the available ac-
cessories is included in the Annex, Section "Accessories".
