NOISE EMISSION
7/26E, 7/31E, 7/41, 7/51
A. COMPRESSED AIR LEAKS
Correct all compressed air leaks during the first shutdown period
after discovery. If severe enough to cause serious noise problems and
efficiency loss, shut down immediately and correct the leak(s).
B. SAFETY AND CONTROL SYSTEMS
Repair or replace all safety and control systems or circuits as
malfunction occurs. No compressor should be operated with either
system bypassed, disabled, or nonfunctional.
C. ACOUSTIC MATERIALS
In daily inspections, observe these materials. Maintain all
acoustic material as nearly as possible in its original condition. Repair
or replace all sections that have: 1) sustained damage, 2) have partially
separated from panels to which they were attached, 3) are missing, or
have otherwise deteriorated due to severe operating or storage
conditions.
D. FASTENERS
All fasteners such as hinges, nuts, bolts, clamps, screws, rivets
and latches should be inspected for looseness after each 100 hours of
operation. They should be retightened, repaired, or − if missing −
replaced immediately to prevent subsequent damage and noise
emission increase.
E. ENCLOSURE PANELS
Enclosure panels should also be inspected at 100 hour
operational intervals. All panels that are warped, punctured, torn, or
otherwise deformed, such that their noise containment function is
reduced, should be repaired or replaced before the next operation
interval. Doors, access panels, and hatch closures especially, should
be checked and adjusted at this time to insure continuous sealing
between gasket or acoustic material and the mating frame.
F. AIR INTAKE AND ENGINE EXHAUST
Engine and compressor air intake and engine exhaust systems
should be inspected after each 100 hours of operation for loose,
damaged, or deteriorated components. Repairs or replacements
should be made before the next period of use.
G. COOLING SYSTEMS
All components of the cooling systems for engine water and
compressor oil should be inspected every 250 hours of use. Any
discrepancies found should be corrected before placing the unit back
in operation. Unrestricted airflow over the radiator and oil cooler must
be maintained at all times during operation.
H. ISOLATION MOUNTS
Engine/airend isolation mounts should be inspected after each
250 hours of operation. Those mounts with cracks or splits in the
molded rubber, or with bent or broken bolts due to operation or storage
in severe environments, all should be replaced with equivalent parts.
I. ENGINE OPERATION
Inspect and maintain engine condition and operation as
recommended in the manuals supplied by the engine manufacturer.
J. FUELS AND LUBRICANTS
Use only the types and grades of fuels and lubricants
recommended in the Ingersoll−Rand Company and Engine
Manufacturer’s Operator and Maintenance Manuals.

precisely to avoid damaging the product, process or its surroundings.
NOTES
Notes are used for supplementary information.
General Information
Never operate unit without first observing all safety warnings and
carefully reading the operation and maintenance manual shipped from
the factory with this machine.
Ensure that the operator reads and understands the decals and
consults the manuals before maintenance or operation.
Ensure that the Operation and Maintenance manual, and the
manual holder, are not removed permanently from the machine.
Ensure that maintenance personnel are adequately trained,
competent and have read the Maintenance Manuals.
Make sure that all protective covers are in place and that the
canopy/doors are closed during operation.
The specification of this machine is such that the machine is not
suitable for use in flammable gas risk areas. If such an application is
required then all local regulations, codes of practice and site rules must
be observed. To ensure that the machine can operate in a safe and
reliable manner, additional equipment such as gas detection, exhaust
spark arrestors, and intake (shut−off) valves may be required,
dependant on local regulations or the degree of risk involved.
A weekly visual check must be made on all fasteners/fixing screws
securing mechanical parts. In particular, safety−related parts such as
coupling hitch, drawbar components, road−wheels, and lifting bail
should be checked for total security.
All components which are loose, damaged or unserviceable, must
be rectified without delay.
Air discharged from this machine may contain carbon monoxide or
other contaminants which will cause serious injury or death. Do not
breathe this air.
This machine produces loud noise with the doors open or service
valve vented. Extended exposure to loud noise can cause hearing loss.
Always wear hearing protection when doors are open or service valve
is vented.
Never inspect or service unit without first disconnecting battery
cable(s) to prevent accidental starting.
Do not use petroleum products (solvents or fuels) under high
pressure as this can penetrate the skin and result in serious illness.
wear eye protection while cleaning unit with compressed air to prevent
debris from injuring eye(s).
Rotating fan blade can cause serious injury. Do not operate without
guard in place.
Use care to avoid contacting hot surfaces (engine exhaust manifold
and piping, air receiver and air discharge piping, etc.).
Ether is an extremely volatile, highly inflammable gas. When it is
specified as a starting aid, use sparingly. DO NOT USE ETHER IF THE
MACHINE HAS GLOW PLUG STARTING AID OR ENGINE DAMAGE
WILL RESULT.
Never operate unit with guards, covers or screens removed. Keep
hands, hair, clothing, tools, blow gun tips, etc. well away from moving
parts.
Compressed air
Compressed air can be dangerous if incorrectly handled. Before
doing any work on the unit, ensure that all pressure is vented from the
system and that the machine cannot be started accidentally.
Ensure that the machine is operating at the rated pressure and that
the rated pressure is known to all relevant personnel.
All air pressure equipment installed in or connected to the machine
must have safe working pressure ratings of at least the machine rated
pressure.
If more than one compressor is connected to one common
downstream plant, effective check valves and isolation valves must be
fitted and controlled by work procedures, so that one machine cannot
accidentally be pressurised / over pressurised by another.
Compressed air must not be used for a direct feed to any form of
breathing apparatus or mask.
High Pressure Air can cause serious injury or death. Relieve
pressure before removing filler plugs/caps, fittings or covers.
Air pressure can remain trapped in air supply line which can result
in serious injury or death. Always carefully vent air supply line at tool
or vent valve before performing any service.
The discharged air contains a very small percentage of compressor
lubricating oil and care should be taken to ensure that downstream
equipment is compatible.
If the discharged air is to be ultimately released into a confined
space, adequate ventilation must be provided.
When using compressed air always use appropriate personal
protective equipment.
All pressure containing parts, especially flexible hoses and their
couplings, must be regularly inspected, be free from defects and be
replaced according to the Manual instructions.
Avoid bodily contact with compressed air.
The safety valve located in the separator tank must be checked
periodically for correct operation.
Whenever the machine is stopped, air will flow back into the
compressor system from devices or systems downstream of the
machine unless the service valve is closed. Install a check valve at the
machine service valve to prevent reverse flow in the event of an
unexpected shutdown when the service valve is open.
SAFETY
22
7/26E, 7/31E, 7/41, 7/51
Disconnected air hoses whip and can cause serious injury or death.
Always attach a safety flow restrictor to each hose at the source of
supply or branch line in accordance with OSHA Regulation 29CFR
Section 1926.302(b).
Never allow the unit to sit stopped with pressure in the
receiver−separator system.
Materials
The following substances may be produced during the operation of
this machine:
. brake lining dust
. engine exhaust fumes
AVOID INHALATION
Ensure that adequate ventilation of the cooling system and exhaust
gases is maintained at all times.
The following substances are used in the manufacture of this
machine and may be hazardous to health if used incorrectly:
. compressor lubricant
. engine lubricant
. preservative grease
. rust preventative
. diesel fuel
. battery electrolyte
AVOID INGESTION, SKIN CONTACT AND INHALATION OF
FUMES.
Should compressor lubricant come into contact with the eyes, then
irrigate with water for at least 5 minutes.
Should compressor lubricant come into contact with the skin, then
wash off immediately.
Consult a physician if large amounts of compressor lubricant are
ingested.
Consult a physician if compressor lubricant is inhaled.
Never give fluids or induce vomiting if the patient is unconscious or
having convulsions.
Safety data sheets for compressor and engine lubricants should be
obtained from the lubricant supplier.
Never operate the engine of this machine inside a building without
adequate ventilation. Avoid breathing exhaust fumes when working on
or near the machine.
This machine may include such materials as oil, diesel fuel,
antifreeze, brake fluid, oil/air filters and batteries which may require
proper disposal when performing maintenance and service tasks.
Contact local authorities for proper disposal of these materials.
Battery
A battery contains sulphuric acid and can give off gases which are
corrosive and potentially explosive. Avoid contact with skin, eyes and
clothing. In case of contact, flush area immediately with water.
DO NOT ATTEMPT TO SLAVE START A FROZEN BATTERY
SINCE THIS MAY CAUSE IT TO EXPLODE.
Exercise extreme caution when using booster battery. To jump
battery, connect ends of one booster cable to the positive (+) terminal
of each battery. Connect one end of other cable to the negative (−)
terminal of the booster battery and other end to a ground connection
away from dead battery (to avoid a spark occurring near any explosive
gases that may be present). After starting unit, always disconnect
cables in reverse order.
Radiator
Hot engine coolant and steam can cause injury. Ensure that the
radiator filler cap is removed with due care and attention.
Do not remove the pressure cap from a HOT radiator. Allow radiator
to cool down before removing pressure cap.
Generator sets
The generator set is designed for safety in use. However, the
responsibility for safe operation rests with those who install, use and
maintain it. The following safety precautions are offered as a guide,
which, if conscientiously followed, will minimise the possibility of
accidents throughout the useful life of this equipment.
Emergency Stop Controls
Important Note:− In addition to the key operated emergency stop
control on the main control panel, a second control is provided at the
socket control panel in the event of electrical hazards associated with
generator operation. Use this second control to immediately isolate all
electrical power to all sockets, then use the key control to stop the
engine.
Operation of the generator must be in accordance with recognised
electrical codes and local health and safety codes.
The generator set should be operated by those who have been
trained in its use and delegated to do so, and who have read and
understand the operator’s manual. Failure to follow the instructions,
procedures and safety precautions in the manual may increase the
possibility of accidents and injuries.
Do not start the generator set unless it is safe to do so. Do not
attempt to operate the generator set with a known unsafe condition. Fit
a danger notice to the generator set and render it inoperative by
disconnecting the battery and disconnecting all ungrounded
conductors so others who may not know of the unsafe condition will not
attempt to operate it until the condition is corrected.
An earth point is provided beneath the socket outlets.
The generator set should only be used with the earth point
connected directly to the general earth/ground mass. An earth spike kit
is available as an optional extra for this purpose (refer to the parts
catalogue).
WARNING: DO NOT OPERATE THE MACHINE UNLESS IT HAS
BEEN SUITABLY EARTHED.
Generator sets must be connected to the load only by trained and
qualified electricians who have been delegated to do so, and when
required by applicable regulations, their work should be inspected, and
accepted by the inspection agency having authority, prior to attempting
to operate the generator set.
Do not make contact with electrically energised parts of the
generator set and/or interconnecting cables or conductors with any
part of the body or with any non−insulated conductive object.
SAFETY
23
7/26E, 7/31E, 7/41, 7/51
Make sure the generator set is effectively grounded in accordance
with all applicable Regulations prior to attempting to make or break load
connections and prior to attempting operation.
Do not attempt to make or break electrical connections to generator
sets standing in water or on wet ground.
Prior to attempting to make or break electrical connections at the
generator set, stop the engine, disconnect the battery and disconnect
and lock out the ungrounded conductors at the load end.
Keep all parts of the body and any hand−held tools or other
conductive objects, away from exposed live parts of the generator set
engine electrical system. Maintain dry footing, stand on insulating
surfaces and do not contact any other portion of the generator set when
making adjustments or repairs to exposed live parts of the generator
set engine electrical system.
Replace the generator set terminal compartment cover as soon as
connections have been made or broken. Do not operate the generator
set without the terminal cover secured firmly in place.
Close and lock all access doors when the generator set is left
unattended.
Do not use extinguishers intended for Class A or Class B fires on
electrical fires. Use only extinguishers suitable for class BC or class
ABC fires.
Keep the towing vehicle or equipment carrier, generator set,
connecting cables, tools and all personnel at least 3 metres from all
power lines and buried power cables, other than those connected to the
generator set.
Attempt repairs only in clean, dry, well lighted and ventilated areas.
Connect the generator set only to loads and/or electrical systems
that are compatible with its electrical characteristics and that are within
it’s rated capacity.
Transport
When loading or transporting machines ensure that the specified
lifting and tie down points are used.
When loading or transporting machines ensure that the towing
vehicle, its size, weight, towing hitch and electrical supply are all
suitable to provide safe and stable towing at speeds either, up to the
legal maximum for the country in which it is being towed or, as specified
for the machine model if lower than the legal maximum.
Ensure that the maximum trailer weight does not exceed the
maximum gross weight of the machine (by limiting the equipment load),
limited by the capacity of the running gear.
Note:
Gross mass (on data plate) is for the basic machine and fuel only,
excluding any fitted options, tools, equipment and foreign materials.
Before towing the machine, ensure that:−
. the tyres and towing hitch are in a serviceable condition.
. the canopy is secure.
. all ancillary equipment is stored in a safe and secure manner.
. the brakes and lights are functioning correctly and meet necessary
road traffic requirements.
. break-away cables/safety chains are connected to the towing
vehicle.
The machine must be towed in a level attitude in order to maintain
correct handling, braking and lighting functions. This can be achieved
by correct selection and adjustment of the vehicle towing hitch and, on
variable height running gear, adjustment of the drawbar.
To ensure full braking efficiency, the front (towing eye) section must
always be set level.
When adjusting variable height running gear:−
Ensure front (towing eye) section is set level
When raising towing eye, set rear joint first, then front joint.
When lowering towing eye, set front joint first, then rear joint.
After setting, fully tighten each joint by hand and then tighten further to
the next pin. Refit the pin.
When parking always use the handbrake and, if necessary, suitable
wheel chocks.
Make sure wheels, tyres and tow bar connectors are in safe
operating condition and tow bar is properly connected before towing.
Safety chains / connections and their adjustment
The legal requirements for the joint operation of the breakaway
cable and safety chains are as yet unidentified by 71/320/EEC or UK
regulations. Consequently we offer the following advice / instructions.
Where brakes only are fitted:
a) Ensure that the breakaway cable is securely coupled to the
handbrake lever and also to a substantial point on the towing vehicle.
b) Ensure that the effective cable length is as short as possible, whilst
still allowing enough slackness for the trailer to articulate without the
handbrake being applied.
Where brakes and safety chains are fitted:
a) Loop the chains onto the towing vehicle using the towing vehicle
hitch as an anchorage point, or any other point of similar strength.
b) Ensure that the effective chain length is as short as possible whilst
still allowing normal articulation of the trailer and effective operation of
the breakaway cable.
Where safety chains only are fitted:
a) Loop the chains onto the towing vehicle using the towing vehicle
hitch as an anchorage point, or any other point of similar strength.
b) When adjusting the safety chains there should be sufficient free
length in the chains to allow normal articulation, whilst also being short
enough to prevent the towbar from touching the ground in the event of
an accidental separation of the towing vehicle from the trailer.
