Safety Section
General Hazard Information
Keep the engine free from foreign material. Remove
debris, oil, tools, and other items from the deck, from
walkways, and from steps.
Never put maintenance fluids into glass containers.
Drain all liquids into a suitable container.
Obey all local regulations for the disposal of liquids.
Use all cleaning solutions with care.
Report all necessary repairs.
Do not allow unauthorized personnel on the
equipment.
Disconnect the batteries when maintenance is
performed or when the electrical system is serviced.
Disconnect the battery ground leads. Tape the leads
to help prevent sparks. If equipped, allow the diesel
exhaust fluid to be purged before disconnecting the
battery.
Perform maintenance on the engine with the
equipment in the servicing position. Refer to the OEM
information for the procedure for placing the
equipment in the servicing position.
Do not attempt any repairs that are not understood.
Use the proper tools. Replace any equipment that is
damaged or repair the equipment.
For initial start-up of a new engine or for starting an
engine that has been serviced, make provisions to
stop the engine if an overspeed occurs. The stopping
of the engine may be accomplished by shutting off
the fuel supply and/or the air supply to the engine.
Ensure that only the fuel supply line is shut off.
Ensure that the fuel return line is open.
Start the engine from the operators station (cab).
Never short across the starting motor terminals or the
batteries. This action could bypass the engine neutral
start system and/or the electrical system could be
damaged.
Engine exhaust contains products of combustion
which may be harmful to your health. Always start the
engine and operate the engine in a ventilated area. If
the engine is in an enclosed area, vent the engine
exhaust to the outside.
Use caution when cover plates are removed.
Gradually loosen, but do not remove the last two
bolts or nuts that are located at opposite ends of the
cover plate or the device. Before removing the last
two bolts or nuts, pry the cover loose to relieve any
spring pressure or other pressure.
Pressure Air and Water
Pressurized air and/or water can cause debris and/or
hot water to be blown out. This action could result in
personal injury.
The direct application of pressurized air or
pressurized water to the body could result in personal
injury.
When pressurized air and/or water is used for
cleaning, wear protective clothing, protective shoes,
and eye protection. Eye protection includes goggles
or a protective face shield.
The maximum air pressure for cleaning purposes
must be below 205 kPa (30 psi). The maximum
water pressure for cleaning purposes must be below
275 kPa (40 psi).
Fluid Penetration
Pressure can be trapped in the hydraulic circuit long
after the engine has been stopped. The pressure can
cause hydraulic fluid or items such as pipe plugs to
escape rapidly if the pressure is not relieved
correctly.
Do not remove any hydraulic components or parts
until pressure has been relieved or personal injury
may occur. Do not disassemble any hydraulic
components or parts until pressure has been relieved
or personal injury may occur. Refer to the OEM
information for any procedures that are required to
relieve the hydraulic pressure.
Illustration 5
Always use a board or cardboard when you check for
a leak. Leaking fluid that is under pressure can
penetrate body tissue. Fluid penetration can cause
serious injury and possible death. A pin hole leak can
cause severe injury. If fluid is injected into your skin,
you must get treatment immediately. Seek treatment
from a doctor that is familiar with this type of injury.
Containing Fluid Spillage
Care must be taken to ensure that fluids are
contained during performance of inspection,
maintenance, testing, adjusting, and repair of the
engine. Make provision to collect the fluid with a
suitable container before any compartment is opened
or before any component is disassembled.
