a) Power tool plugs must match the outlet. Never modify the plug in any
way. Do not use any adapter plugs with earthed (grounded) power tools.
Unmodified plugs and matching outlets will reduce risk of electric shock.
b) Avoid body contact with earthed or grounded surfaces, such as
pipes, radiators, ranges and refrigerators.
There is an increased risk of electric shock if your body is earthed or
grounded.
c) Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of electric shock.
d) Do not abuse the cord. Never use the cord for carrying, pulling or
unplugging the power tool. Keep cord away from heat, oil, sharp edges
or moving parts.
Damaged or entangled cords increase the risk of electric shock.
e) When operating a power tool outdoors, use an extension cord suit‐
able for outdoor use.
Use of a cord suitable for outdoor use reduces the risk of electric shock.
f) lf operating a power tool in a damp location is unavoidable, use a
residual current device (RCD) protected supply.
Use of an RCD reduces the risk of electric shock.
a) Stay alert, watch what you are doing and use common sense when
operating a power tool. Do not use a power tool while you are tired or
under the influence of drugs, alcohol or medication.
A moment of inattention while operating power tools may result in
serious personal injury.
b) Use personal protective equipment. Always wear eye protection.
Protective equipment such as a dust mask, non-skid safety shoes, hard
hat or hearing protection used for appropriate conditions will reduce
personal injuries.
c) Prevent unintentional starting. Ensure the switch is in the off-position
before connecting to power source and/or battery pack, picking up or
carrying the tool.
Carrying power tools with your finger on the switch or energising power
tools that have the switch on invites accidents.
d) Remove any adjusting key or wrench before turning the power tool
on.
A wrench or a key left attached to a rotating part of the power tool may
result in personal injury.
e) Do not overreach. Keep proper footing and balance at all times.
This enables better control of the power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair
and clothing away from moving parts.
Loose clothes, jewellery or long hair can be caught in moving parts.
g) lf devices are provided for the connection of dust extraction and col‐
lection facilities, ensure these are connected and properly used.
Use of dust collection can reduce dust-related hazards.

h) Do not let familiarity gained from frequent use of tools allow you to
become complacent and ignore tool safety principles.
A careless action can cause severe injury within a fraction of a second.
a) Do not force the power tool. Use the correct power tool for your
application.
The correct power tool will do the job better and safer at the rate for
which it was designed.
b) Do not use the power tool if the switch does not turn it on and off.
Any power tool that cannot be controlled with the switch is dangerous
and must be repaired.
c) Disconnect the plug from the power source and/or remove the bat‐
tery pack, if detachable, from the power tool before making any adjust‐
ments, changing accessories, or storing power tools.
Such preventive safety measures reduce the risk of starting the power
tool accidentally.
d) Store idle power tools out of the reach of children and do not allow
persons unfamiliar with the power tool or these instructions to operate
the power tool.
Power tools are dangerous in the hands of untrained users.
e) Maintain power tools and accessories. Check for misalignment or
binding of moving parts, breakage of parts and any other condition that
may affect the power tool's operation. lf damaged, have the power tool
repaired before use.
Many accidents are caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean.
Properly maintained cutting tools with sharp cutting edges are less likely
to bind and are easier to control.
g) Use the power tool, accessories and tool bits etc. in accordance with
these instructions, taking into account the working conditions and the
work to be performed.
Use of the power tool for operations different from those intended could
result in a hazardous situation.
h) Keep handles and grasping surfaces dry, clean and free from oil and
grease.
Slippery handles and grasping surfaces do not allow for safe handling
and control of the tool in unexpected situations.
a) Have your power tool serviced by a qualified repair person using only
identical replacement parts.
This will ensure that the safety of the power tool is maintained.
b) Never service damaged battery packs.
Service of battery packs should only be performed by the manufacturer
or authorized service providers.

The specified oscillation emission value was measured in accordance
with a standardised test procedure and can be used to compare the
machine with another device. The specified oscillation emission value
can also be used for an initial assessment of the intermittent duty.
When the device is actually being used, the oscillation emission value
may differ from specified value, depending on the manner in which the
device is used. Depending on the actual conditions of use (intermittent
duty), it may be necessary to specify safety measures to protect the
user.
2.4.3 Operating mode
The Viega Pressgun 6B is an electro-hydraulically operated press
machine. Pressing the start button and keeping it pressed triggers
pressing. The hydraulically operated roller head moves forwards into the
press jaw and closes it with a power of 32 kN.
Power is supplied via a mains connection 220–240 V AC with 50–60 Hz.
The press machine operates by a positively controlled process. This
means:
nDuring the pressing, even when the Start button is temporarily
released, the roller head of the press machine stays in the position
reached.
nThe pressing must be completed in order for the roller head to
return.
For safety reasons, the positive control is enabled only after the press
machine has reached a minimum force.
