•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 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 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 manually operated protection cover (3) prevents individuals from
accidentally reaching into the danger area. The protection cover is fit-
ted with a safety switch (5). The safety switch (5) is closed by the
contact plug (2) when the protection cover is closed. The safety

switch (5) switches off the motor when the protection cover (3) is
opened or the chip box (4) is removed.
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 guard (1) on the protection cover prevents individuals from
reaching into the skiving area when the motor is running. Lift the
guard (1) with the hose and guide the hose centrally through the
opening onto the pin.
Mounted safety equipment must not be removed, bypassed or
avoided.
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 Machine description
3.1 Design and function
Basic machine
(1) Outside skiving tool
(2) Electric motor
(3) Centering pin
(4) Guard
(5) Foot pedal
(6) Chip box
(7) Inside skiving tool
(8) Operation indicator lamp
(9) Main power switch
(10) Change in direction of rotation switch
The hose is guided manually through the guard (4) onto the centering
pin (3) and held by hand during the skiving process. By activating the
foot pedal (5), the outside skiving tool (1) and/or the inside skiving
tool is rotated. The skiving tool (inside / outside) is driven by the elec-
tric motor (2). The selected skiving tool (1/7) skives the hose either on

the inside or outside. The hose is skived from the hose ends. The
skiving dimension is set mechanically in advance. The skiving chips
are collected in the chip box (6).
The skiving direction can be selected using the change in direction of
rotation switch (10) on the control panel.
➢Turn to the right for inside skiving
➢Turn to the left for outside skiving
Inside skiving tool USM 10.2 EcoLine / USM 10.2
The inside skiving tool consists of the pin (2), the inside skiving knife
(1) and the adjusting ring (5).
The skiving depth is set by turning the adjusting ring (5). The adjust-
ing ring is secured to the pin by the hexagon socket threaded pin (4).
The skiving diameter is set by adjusting the inside skiving knife (1).
The inside skiving knife is held by the hexagon socket threaded pin
(3). The inside skiving tool is inserted into the drive shaft (5) and se-
cured using the star-shaped grip.

Outside skiving tool USM 10.2 EcoLine / USM 10.2
The outside skiving tool consists of the main body (1), the cutting arm
(6) and the centering pin (2).
The skiving length is set by adjusting the centering pin (2). The cen-
tering pin (2) is inserted into the drive shaft and secured using the
star-shaped grip (3). The outside skiving knife (4) is held by the cut-
ting arm (6) and secured using the clamp (5). The skiving diameter is
set by turning the star-shaped grip (7). The diameter can be read on
the adjusting scale (8).
The skiving diameter only has to be set for the initial setup or after
re-skiving.
