Safety Precautions
General
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 manual holder if equipped, are
not removed permanently from the machine.
Ensure that maintenance personnel are
adequately trained, competent and have
read the 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 machine
can operate in a safe and reliable manner,
additional equipment such as gas detection,
exhaustsparkarrestors,andintake(shut-off)
valves may be required, dependent on local
regulations or the degree of risk involved.
Air discharged from this machine may
contain carbon monoxide or other
contaminants which will cause serious injury
or death. Do not breathe this air.
Compressed air can be dangerous if
incorrectly handled. Before doing any work
on the unit, ensure that all pressure is vented
fromthesystem andthatthemachinecannot
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 safety valve rating.
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
pressurized or over pressurized by another.
Compressed air must not be used for a feed
to any form of breathing apparatus or mask.
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 periodicallyfor correct
operation.
Never operate unit without first observing all
safety warnings and carefully reading the
operation and maintenance manual shipped
from the factory with this machine.
Never operate the engine of this machine
inside a building without adequate
ventilation. Avoid breathing exhaust fumes
whenworkingonornearthemachine.Donot
alter or modify this machine.
A battery contains sulfuric 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.
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 endof

Safety Operating & Maintenance Manual
Book: 46490694 (03-2010) Rev A 13
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.
HighPressureAir can cause seriousinjuryor
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.
Thismachineproducesloudnoisewithdoors
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 remove the pressure cap from a HOT
radiator. Allow radiator to cool down before
removing pressure cap.
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).
Disconnected air hoses whip and can cause
serious injury or death. Always attach a
safety flow restrictor to each hose at the
sourceofsupplyorbranchlineinaccordance
with OSHA Regulation 29CFR Section
1926.302(b).
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
flammable gas. USE SPARINGLY! DO NOT
use ETHER if unit has GLOW Plug starting
aid. Engine damage will result.
Never allow the unit to sit stopped with the
pressure in receiver-separator system. As a
precaution, open manual blowdown valve.
Never operate unit with guards, covers or
screens removed. Keep hands, hair,
clothing, tools, blow gun tips, etc. well away
from moving parts.
Make sure wheels, tires and tow bar
connectors are in safe operating condition
and tow bar is properly connected before
towing.
Steps for determining correct load limit -
1. Locate the statement “The
weight of cargo should never
exceed xxx kg or xxx lbs” on
your vehicle’s placard.
2. This figure equals the
available amount of cargo
and luggage load capacity.
1. Determine the combined
weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely
exceed the available cargo.
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. Stop machine to add fuel.
Hazardous Substance Precaution
The following substances are used in the
manufacture of this machine and may be
hazardous to health if used incorrectly.Avoid
ingestion, skin contact and breathing fumes
for the following substances:Antifreeze,
Compressor Oil, Engine Lubricating Oil,
Preservative Grease, Rust Preventative,
Diesel Fuel and Battery Electrolyte.
