General Hazard Information

Hexavalent Chromium
Perkins equipment and replacement parts comply
with applicable regulations and requirements where
originally sold. Perkins recommends the use of only
genuine Perkins replacement parts.
Hexavalent chromium has occasionally been
detected on exhaust and heat shield systems on
Perkins engines. Although laboratory testing is the
only accurate way to know if hexavalent chromium is,
in fact, present, the presence of a yellow deposit in
areas of high heat (for example, exhaust system
components or exhaust insulation) may be an
indication of the presence of hexavalent chromium.
Use caution if you suspect the presence of
hexavalent chromium. Avoid skin contact when
handling items that you suspect may contain
hexavalent chromium, and avoid inhalation of any
dust in the suspect area. Inhalation of, or skin contact
with, hexavalent chromium dust may be hazardous to
your health.
If such yellow deposits are found on the engine,
engine component parts, or associated equipment or
packages, Perkins recommends following local
health and safety regulations and guidelines, utilizing
good hygiene, and adhering to safe work practices
when handling the equipment or parts. Perkins also
recommends the following:
• Wear appropriate Personal Protective Equipment
(PPE)
• Wash your hands and face with soap and water
prior to eating, drinking, or smoking, and also
during rest room breaks, to prevent ingestion of
any yellow powder
• Never use compressed air for cleaning areas
suspected of containing hexavalent chromium
• Avoid brushing, grinding, or cutting materials
suspected of containing hexavalent chromium
• Obey environmental regulations for the disposal of
all materials that may contain or have come into
contact with hexavalent chromium
• Stay away from areas that might have hexavalent
chromium particles in the air.
Asbestos Information
Perkins equipment and replacement parts that are
shipped from Perkins engine company limited are
asbestos free. Perkins recommends the use of only
genuine Perkins replacement parts. Use the following
guidelines when you handle any replacement parts
that contain asbestos or when you handle asbestos
debris.
Use caution. Avoid inhaling dust that might be
generated when you handle components that contain
asbestos fibers. Inhaling this dust can be hazardous
to your health. The components that may contain
asbestos fibers are brake pads, brake bands, lining
material, clutch plates, and some gaskets. The
asbestos that is used in these components is usually
bound in a resin or sealed in some way. Normal
handling is not hazardous unless airborne dust that
contains asbestos is generated.
If dust that may contain asbestos is present, there
are several guidelines that should be followed:
• Never use compressed air for cleaning.
• Avoid brushing materials that contain asbestos.
• Avoid grinding materials that contain asbestos.
• Use a wet method to clean up asbestos materials.
• A vacuum cleaner that is equipped with a high
efficiency particulate air filter (HEPA) can also be
used.
• Use exhaust ventilation on permanent machining
jobs.
• Wear an approved respirator if there is no other
way to control the dust.
• Comply with applicable rules and regulations for
the work place. In the United States, use
Occupational Safety and Health Administration
(OSHA) requirements. These OSHA requirements
can be found in “29 CFR 1910.1001”.
• Obey environmental regulations for the disposal of
asbestos.
14 SEBU8190-02
Safety Section
General Hazard Information

• Stay away from areas that might have asbestos
particles in the air.
Dispose of Waste Properly
Illustration 15 g00706404
Improperly disposing of waste can threaten the
environment. Potentially harmful fluids should be
disposed of according to local regulations.

start-up of an engine that has been serviced, make
provision to shut the engine off should an overspeed
occur. This may be accomplished by shutting off the
air and/or fuel supply to the engine.
Engine exhaust contains products of combustion
which may be harmful to your health. Always
start and operate the engine in a well ventilated
area and, if in an enclosed area, vent the exhaust
to the outside.
Inspect the engine for potential hazards.
Do not start the engine or move any of the controls if
there is a “DO NOT OPERATE”warning tag or similar
warning tag attached to the start switch or to the
controls.
Before starting the engine, ensure that no one is on,
underneath, or close to the engine. Ensure that the
area is free of personnel.
If equipped, ensure that the lighting system for the
engine is suitable for the conditions. Ensure that all
lights work properly, if equipped.
All protective guards and all protective covers must
be installed if the engine must be started in order to
perform service procedures. To help prevent an
accident that is caused by parts in rotation, work
around the parts carefully.
Do not start an engine when the governor linkage is
disconnected.
Do not bypass the automatic shutoff circuits. Do not
disable the automatic shutoff circuits. The circuits are
provided in order to help prevent personal injury. The
circuits are also provided in order to help prevent
engine damage.

Engine Starting
If a warning tag is attached to the engine start switch
or to the controls, DO NOT start the engine or move
the controls. Consult with the person that attached
the warning tag before the engine is started.
All protective guards and all protective covers must
be installed if the engine must be started in order to
perform service procedures. To help prevent an
accident that is caused by parts in rotation, work
around the parts carefully.
If there is a possibility that unburned gas remains in
the exhaust system, refer to the purge procedure in
this Operation and Maintenance Manual, “Engine
Starting” topic in the Operation Section.
Always start the engine according to the procedure
that is described in the Operation and Maintenance
Manual, “Engine Starting” topic in the Operation
Section. Knowing the correct procedure will help to
prevent major damage to the engine components.
Knowing the procedure will also help to prevent
personal injury.
To ensure that the jacket water heater (if equipped)
and/or the lube oil heater (if equipped) is working
properly, check the water temperature and the oil
temperature during heater operation.
Engine exhaust contains products of combustion
which can be harmful to your health. Always start the
engine and operate the engine in a well ventilated
area. If the engine is started in an enclosed area,
vent the engine exhaust to the outside.

Ignition Systems

Use the Emergency Stop Button (if equipped) ONLY
in an emergency situation. Do not use the
Emergency Stop Button for normal engine stopping.
After an emergency stop, DO NOT start the engine
until the problem that caused the emergency stop
has been corrected.
On the initial start-up of a new engine or an engine
that has been serviced, make provisions to stop the
engine if an overspeed occurs. This procedure may
be accomplished by shutting off the fuel supply to the
engine, or shutting off the ignition system.

Electrical System
Never disconnect any charging unit circuit or battery
circuit cable from the battery when the charging unit
is operating. A spark can cause the combustible
gases that are produced by some batteries to ignite.
To help prevent sparks from igniting combustible
gases that are produced by some batteries, the
negative “−”cable should be connected last from the
external power source to the negative “−”terminal of
the starting motor. If the starting motor is not
equipped with a negative “−”terminal, connect the
cable to the engine block.
Check the electrical wires daily for wires that are
loose or frayed. Tighten all loose electrical
connections before the engine is started. Repair all
frayed electrical wires before the engine is started.
See the Operation and Maintenance Manual for
specific starting instructions.
Grounding Practices
Note: All ground lines must return to the battery
ground.
Illustration 18 g01217202
Typical example
(1) Starting motor to ground
(2) Battery negative to engine
Correct grounding for the engine electrical system is
necessary for optimum engine performance and
reliability. Incorrect grounding will result in
uncontrolled electrical circuit paths and in unreliable
electrical circuit paths.
Uncontrolled electrical circuit paths can result in
damage to the crankshaft bearing journal surfaces
and to aluminum components.
The connections for the grounds should be tight and
free of corrosion. The engine alternator must be
grounded to the negative “-”battery terminal with a
wire that is adequate to handle the full charging
current of the alternator.
The power supply connections and the ground
connections for the engine electronics should always
be from the isolator to the battery.
