EN OPERATING MANUAL : Compressor Screw
2-2 Notes on the compressor
WINAIR screw compressors are the result of many
years of research and development. These prerequisites
combined with high quality standards guarantee the
manufacture of screw compressors providing a long
service life, high reliability and cost-eective operation.
It stands to reason that all requirements concerning
environmental protection are met.
2-3 Intended use
The machine / unit has been constructed in accordance
with state-of-the-art technology and the recognized
safety regulations.
Nevertheless, the operator or third parties may be
exposed to risk to life and limb in the course of the use
of the compressor (e.g. through ying pieces of building
material, swirling dirt or dust particles, electric current
or thermal impairment, vibration, noise or mechanical
hazard), and the machine or other tangible assets may be
impaired, for reasons that could not have been avoided
through preventive constructional safety measures.
Hazards occur particularly, when:
■ the compressor is not used for its intended purpose
■ the compressor is not operated by trained personnel
■ unauthorized changes or modications are carried
out on the compressor
■ you are not wearing the required protective clothing
■ you do not comply with the safety instructions
■ you do not observe the information in the operating
instructions.
For this reason every person involved in the operation,
maintenance and repair of the compressor must read and
observe the operation manual and the safety regulations.
This is to be conrmed by signature as required.
Furthermore, the following naturally apply:
■ the relevant accident prevention regulations
■ generally recognized safety and trac regulations
■ particular national regulations
The compressor is designed for providing compressed
air:
■ for operating compressed-air appliances
■ for conveying bulk material
■ for sandblasting and paint-spraying operations
■ for cleaning machines and shuttering material
■ for blow-cleaning drilled holes
Any other use, or any additional use, for example as
respiratory air, is regarded as not being for the originally
intended purpose.
The manufacturer / supplier accepts no liability for any
resulting damage. The risk is assumed by the user alone.
The compressor may only be used in a technically perfect
condition, for its intended purpose, with appropriate
awareness of safety regulations and hazards, subject to
compliance with the operating manual.
In particular, faults representing safety hazards are to be
corrected at once.

ENOPERATING MANUAL : Compressor Screw
3-4 Loading / Relocation / Travelling
Loading / Relocation
All loose parts that could fall down when the machine
is lifted must rst be removed or secured; moveable or
pivoted parts like doors, etc. must be immobilized.
For lifting heavy parts, lifting gear and heavy-lift facilities
with the appropriate capacities, which have been
checked and approved in accordance with local safety
regulations, must be used.
For lifting machines or machine parts with one or more
lifting eye(s), only hooks or shackles complying with local
safety regulations may be used. Never fasten cables,
chains or ropes directly to or through lifting eyes.
Lifting hooks, lifting eyes, shackles, etc. must never be
bent and must always be stressed in alignment with the
loadcarrying axis. The load bearing capacity of the lifting
gear is reduced if the lifting force is applied at an angle
to the axis.
All bearing parts must be stressed vertically, as far as
possible, for maximum safety and optimum performance
of the lifting gear. If required, a support is to be installed
between the lifting gear and the load.
Secure the load properly.
If heavy loads are to be transported by means of lifting
gear, it is strictly forbidden to stay under or near this load.
Never leave the load suspended on the lifting gear.
Acceleration and deceleration of the load must take
place within the admissible limits.
The lifting gear must be set up in such a way that the
load is lifted vertically. If this is not possible, take relevant
precautions in order to prevent the load from swinging.
For example, two lifting gears can be used, both with an
inclination angle of not more than 30° to the vertical.
Appoint an experienced supervisor for the lifting
procedure.
Lift the machine only in accordance with the operating
instructions (fastening points for the load lifting tackle,
etc.) using suitable lifting gear.
Always use a suitable transport vehicle with sucient
load carrying capacity.
Before and immediately after completion of loading
secure the machine / unit against accidental shifting.
Attach corresponding warning signs.
Before putting the machine / unit back into operation, the
securing devices have to be duly removed.
Parts, which have to be removed for transport purposes,
must be carefully retted and xed again before putting
the machine / unit back into operation.
When putting the machine / unit back into operation
again, only proceed in accordance with the operating
instructions.
Travelling
Make sure that the air vessels are depressurized.
Lift and secure supporting gear.
Check to make sure that the wheels are properly
tightened, that the tyres are in a roadworthy condition,
that the tyre pressure is correct.
Before transporting the machine, always check to make
sure that the accessories are rmly attached so that they
can cause no accidents.
Always keep a safe distance to foundation ditches and
embankments.
Never travel across slopes transversely; always keep
working equipment near ground level (for example, do
not place it on the bodywork).
Avoid all operations that adversely aect the stability of
the machine.
12
EN OPERATING MANUAL : Compressor Screw
3-5 Installation / Starting and Normal
operation
Installation
In addition to the general technical operation in
accordance with the stipulations of the local authorities,
we would like to refer in particular to the following
regulations.
Before switching on the machine / unit, or starting it up,
make sure that nobody can be injured by the machine as
it starts up.
The system has to be set up in such a way that it is
adequately accessible and the required cooling is
guaranteed. Never block the air intake.
The air intake is to be located so that no hazardous
constituent (solvent vapour, etc., but also dusts and
other hazardous material) can be sucked in. This applies
also to ying sparks.
The air intake is to be positioned so that no loose clothing
of persons can be sucked in.
The pressure line connected to the air outlet of the
system must be tted stress free.
Compressed air lines have to be clearly marked in line
with the local regulations.
If several compressors are arranged in a system,
manually operated valves have to be installed so that each
machine may be shut o individually. When operating
pressure systems, do not rely on the eectiveness of
check valves alone to isolate these systems.
Safety equipment, protective covers or insulation must
not be removed or modied. Any pressure vessel, which
is located outside the system, the permissible operating
pressure of which is higher than the atmospheric pressure
and which is tted with two or more pressure supply lines,
has to be equipped with additional safety equipment,
which will automatically prevent the admissible operating
pressure from rising by more than 10%.
Pipes and / or other parts with a surface temperature
higher than 80°C have to be suitably identied and
shielded against touching.
Electrical connections must comply with local regulations.
Install the machine so that it is as horizontal as possible;
a slight inclination is permissible (see chapter 5).
Set up the machine in such a way that no inlets, outlets
or gates are blocked, even when the doors are open.
If a machine with a combustion engine has to work in a
re-risk environment, the unit must be tted with a spark
catcher.
In dusty environments, set up the machine in such a way
that the wind does not blow dust in its direction.
During operation in clean environments / the intervals for
cleaning the air intake lter and the cooler elements are
much longer.
Do not install the machine directly in front of walls. Make
sure that the warm air coming from the engine and
cooling systems is not drawn into the air intake under
any circumstances. Drawing this warm air in through the
engine or cooler fan could lead to overheating; it is drawn
into the combustion chamber, this will result in a loss of
power.
Never relocate the machine if external lines or hoses
are connected to the discharge valves, in order to avoid
damage to the valve and / or collecting pipe and hoses.
No force may be exerted on the discharge valves, for
example by pulling the hoses.
Make sure that:
■ all bolted connections have been tightened,
■ all electrical wiring has been connected correctly and
is in good condition,
■ the engine exhaust system is operationally safe and
that no inammable material is in its vicinity,
■ The wheel nuts are properly tightened; never exceed
the specied torques.
13
ENOPERATING MANUAL : Compressor Screw
Normal operation
Before starting work, make yourself familiar with the
working environment at the place of operation. The
working environment includes, for example, obstacles in
the working and transport areas, the carrying capacity of
the ground, and any necessary cordoning o of the site
from public trac areas.
Take the necessary precautions to make sure that the
machine / unit is only operated in a safe, functional
condition.
Only operate the machine when all protective devices,
shutdown devices, soundinsulating equipment and
extraction equipment is in place and working.
Be careful: loose articles of clothing, hair or limbs can
still be drawn in by revolving parts.
Check regularly that:
■ all means of protection are correctly tted and xed,
■ all hoses and / or pipes within the system are in
good condition, rmly xed and do not chafe,
■ there are no leakages (fuel, oil or coolant),
■ all ttings are rmly tightened,
■ all wires are connected correctly and are in good
condition,
■ all safety valves and other pressure relief
mechanisms are in good order and not blocked by
e.g. dirt or paint,
■ the safety mechanisms are fully functional.
All connected components must be of the correct size
and be suitable for the specied operating pressure and
temperature.
Only use hose couplings and ttings of the right type and
the correct size.
Before blowing through a hose or an air pipe ensure that
the open end is positively held. A free end whips and can
cause injuries or damage.
Refrain from any working method which is doubtful in
terms of safety.
Never play around with compressed air.
Never aim compressed air at your skin or at other
persons.
Never use compressed air to clean your clothing. When
using compressed air to clean equipment take the utmost
care and always wear protective goggles.
The compressed air generated by these compressors
must never be used for breathing unless it has been
conditioned for those applications in line with the «safety
requirements for respiratory air».
When breathing apparatus with car tridges is used, make
sure that the correct cartridge has been inserted and that
its service life has not expired.
Never use the machine in environments where the
possibility cannot be ruled out that inammable or toxic
vapours may be taken in.
Never operate the system at pressures and temperatures
below or above the values indicated in the technical data
sheet.
Persons working in environments or rooms in which the
acoustic pressure is 85 dB(A) or higher must wear ear
protectors.
Caution: This may impair communication between
persons. Warnings may not be heard. Inform supervisor.
Never ll up with fuel while the engine is running. Make
sure that the fuel does not come into contact with hot
machine parts.
Do not smoke while lling up with fuel.
Filling up at a pump can cause staticelectricity and
possibly sparks. In order to avoid this, a ground cable
must be connected to the system while it is being lled
up.
The machine must not be used in closed or poorly
ventilated areas (tunnel, cellar, ...). The exhaust
emissions of combustion engines contain carbon
monoxide - a lethal gas.
If a machine with such an engine has to work in an
enclosed room, the exhaust gases must therefore be
conducted outside or to the open air by means of a hose
or pipe with an internal diameter of at least 100 mm. The
use of extraction systems is highly recommended in test
rooms for mobile machines.
14
EN OPERATING MANUAL : Compressor Screw
Before connecting or disconnecting hoses, always close
the compressor outlet valves.
Before disconnecting a hose, always make sure that it is
not under pressure.
A hose connected to an air valve must be tted with a
safety wire for operating pressures above 7 bar; it is in
fact recommended that this safety device should be used
for pressures above 4 bar. The steel wire has a diameter
of 8 mm and is rmly clamped to the hose at least every
500 mm. Both ends are tted with cable lugs.
Check the machine / unit for external damage and faults
at least once per shift.
Any changes noticed (included changes in the operating
performance) must be reported immediately to the
authority or person in charge. If necessary, shut down
and secure the machine immediately.
In case of malfunction, shut down and secure the
machine / unit immediately. Have malfunctions corrected
immediately.
Observe operating instructions for startup and shutdown
procedures as well as control displays.
3-6 Special work / Maintenance
Carefulness
Observe the adjusting, maintenance and inspection
activities and intervals set out in the operating
instructions, including information on the replacement of
parts and equipment. These activities may be carried out
by skilled personnel only.
Maintenance work, tests and repairs should be carried
