General Hazard Information
Keep the equipm
ent free from foreign material.
Remove debris, oil, tools, and other items from the
deck, from walkways, and from steps.
Secure all loose items such as lunch boxes, tools,
and other items that are not a part of the equipment.
Know the appropriate work site hand signals and
the personnel that are authorized to give the hand
signals. Ac
cept hand signals from one person only.
Do not smoke when you service an air conditioner.
Also, do not
smoke if refrigerant gas may be present.
Inhaling the fumes that are released from a flame that
contacts air conditioner refrigerant can cause bodily
harm or dea
th. Inhaling gas from air conditioner
refrigerant through a lighted cigarette can cause
bodily harm or death.
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 cl
eaning solutions with care. Report all
necessary repairs.
Do not al
low unauthorized personnel on the
equipment.
Unless y
ou are instructed otherwise, perform
maintenance with the equipment in the servicing
position. Refer to Operation and Maintenance Manual
for the
procedure for placing the equipment in the
servicing position.
When y
ou perform maintenance above ground level
use appropriate devices such as ladders or man lift
machines. If equipped, use the machine anchorage
point
s and use approved fall arrest harnesses and
lanyards.
Pressurized Air and Water
Pres
surized air and/or water can cause debris
and/or hot water to be blown out. This could result in
personal injury.
When pressurized air and/or pressurized water is
used for cleaning, wear protective clothing, protective
sho
es, and eye protection. Eye protection includes
goggles or a protective face shield.
Th
e maximum air pressure for cleaning purposes
must be reduced to 205 kPa (30 psi) when the
nozzle is deadheaded and the nozzle is used with
an
effective chip deflector and personal protective
equipment. The maximum water pressure for
cleaning purposes must be below 275 kPa (40 psi).
Trapped Pressure
Pressure can b
e trapped in a hydraulic system.
Releasing trapped pressure can cause sudden
machine movement or attachment movement. Use
caution if you
disconnect hydraulic lines or fittings.
High pressure oil that is released can cause a hose to
whip. High pressure oil that is released can cause oil
to spray. Flu
id penetration can cause serious injury
and possible death.
Fluid Penetration
Pressure ca
n 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 rap
idly if the pressure is not relieved correctly.
Do not remove any hydraulic components or parts
until pres
sure has been relieved or personal injury
may occur. Do not disassemble any hydraulic
components or parts until pressure has been relieved
or person
al injury may occur. Refer to the Service
Manual for any procedures that are required to
relieve the hydraulic pressure.

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 in order to ensure that fluids
are contained during performance of inspection,
maintenance, testing, adjusting and repair of the
equipment. Prepare to collect the fluid with suitable
containers before opening any compartment or
disassembling any component that contains fluids.
