2 Safety instructions
2.1 Presentation of warnings
Warning notes in the Operation Manual warn against risks involved
with the handling of the machine/unit. Risk levels are identified as fol-
lows:
The signal word HAZARD identifies an imminent hazard resulting in
serious injuries or death. This warning is supplemented by a triangu-
lar hazard symbol.
The signal word WARNING identifies a potentially hazardous situa-
tion, which might result in serious injuries or death. This warning is
supplemented by a triangular hazard symbol.
The signal word CAUTION identifies a potentially hazardous situa-
tion, which might result in light injuries. This warning is supplemented
by a triangular hazard symbol.
The signal word ATTENTION identifies a potentially hazardous situa-
tion, in which the product or property in the environment may be dam-
ages. This warning is supplemented by a hazard symbol or a excla-
mation mark.
2.2 Intended use
This machine is a hose skiving machine for industrial use, only suita-
ble for skiving wire-reinforced hydraulic hoses, see “Technical Data”
in Section 3.
Intended purposes include:
•single workplace for one person only,
•single stroke with manual feed and withdrawal,
•operating temperature between 10 °C and 35 °C,
•operation in a closed 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 in-
cludes 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 modification of the machine;
•use in explosive environments;
•use of impermissible skiving domes;
•use of impermissible skiving blades;
•skiving of workpieces with ripped out wires,
•skiving without safety equipment,
•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
The skiving process and the skiving knife change-over imply a cutting
risk.
•Keep sufficient distance to the skiving knives during operation.
•Take care when changing the skiving knives and wear protective
gloves.
Risk of squeezing
There is risk of getting squeezed between the protection cover and
the chassis when closing the protection cover.
•Use the strap grip to close the protection cover.
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 Risks imposed by noise
The noise level meter acc. to IEC 804, Class 2, was calibrated before
measuring.
The operation of the machine/unit causes noise emissions of 60
dB(A) at the workplace. Noise protection is not required.
Higher noise emissions may occur when other machine/unitry is sim-
ultaneously used at the workplace. The machine/unit owner must pro-
vide for appropriate protection, e.g.

•instruct staff to wear ear protection,
•provide information/instructions on risks,
•identify hazardous areas,
•provide health monitoring.
2.3.4 Risks imposed by substances
Oils, greases and emulsions may penetrate the skin. When handling
hazardous substances, oils and greases, the manufacturers' safety
instructions have to be observed. Apply skin protection appropriate
for the hazardous substances used.
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 designed as the area 1 metre all around the ma-
chine (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 switch on the control
panel.
Immediately activate the emergency-stop switch (1) on the control
panel in cases of emergency.
Remedy the cause of the emergency stop first before unlocking the
emergency-stop switch.

2.4.3 Protection equipment
The protection hood (1) covers the skiving area of the unit and is fit-
ted with a safety switch. The safety switch is closed by the contact
plug when the protection hood is closed. The safety switch switches
off the motor when the hood is opened.
DANGER!
Risk of injuries by manipulated safety switch
The manually operated protection cover is an essential safety
feature of the machine.
•Never operate the machine with a non-functional safety
switch.
The protective flaps (2) of the machine are mechanically preten-
sioned by springs. This force must first be overcome before the work-
piece can be inserted into the skiving area. This protects the operator
from unintentionally reaching into the danger area. The protective
flaps can be opened via the "Emergency opening" lever (3).
2.4.4 Warning signs on the machine

Crushing risk
on the cover
Cutting risk
on the skiving knives
Danger from electric current
at the power supply line
Illegible or missing warning signs must immediately be replaced by
the owner.

3.1 Design and function
Basic machine
(1) Protection hood
(2) Safety switch
(3) Electric motor
(4) Main power switch
(5) Control system
(6) Opening lever
(7) Protective flaps
(8) Hose guide housing
With USM 100, hose lines with wire braiding up to DN 50 and hose
lines with wire spiral up to DN 50 - 6 SP can be peeled inside and
outside simultaneously.
The machine is bolted to a table (option) or other horizontal support.
The skiving residues can be collected in a waste cart (option).

The hose is guided by hand through the protective flaps (7) centrally
against the peeling blades. The hands remain outside the machine
during this process. The motor operated skiving blades (3) rotate
against each other and skive the hose line inside and outside simulta-
neously from the hose end. The skiving residues fall out laterally
downwards and are collected by the trolley under the skiving ma-
chine. After skiving, the workpiece is removed by hand.
The skiving speed can be selected using the switch on the control
panel.
