SAFETY PROCEDURES AND
WARNINGS
WARNINGS:
The following
statements
of warning
apply
all or in part
wherever the symbol appears in the maintenance
procedures. Failure to observe these
precautions
may
result in serious injury to those performing the work
and/or bystanders.
• The use of an air jet, which must be less than 30
p.s.i.g., to blow parts clean or to blow them dry
after being cleaned with a solvent will cause
particles of dirt and/or droplets of the cleaning
solvent to be airborne. Wire brushing may also
cause particles of dirt, rust, and scale to become
airborne. These conditions may cause skin and/or
eye irritation.
• When using an air jet, do not direct it toward
another
person.
Improper
use of air jet could result
in bodily injury.
• Personal eye protection must be worn when
performing any work on this device or its
components parts to avoid any possible injury to
the eyes.
• The use of
solvents
as
cleaning
agents and the use
of lubricants can involve health and/or safety
hazards. The manufacturers of the solvents and
lubricants should
be
contacted
for
safety
data (such
as OSHA Form OSHA-20 or its equivalent). The
recommended precautions and procedures of the
manufacturers should be followed.
• When performing any test or work on devices or
equipment while they are on the vehicle (on car
test, etc.)
special precautions must be taken to
insure
that vehicle movement will not occur which could
result in injury to personnel and/or damage to
equipment.
• Assembly may be under a spring load. Exercise
caution during disassembly so that no parts "Fly
Out" and cause bodily injury.
• All air supply and/or electric current to this device
and/or to any components part must be cut-off
before this device and/or any component part is
removed from the equipment arrangement.
• "Bottled" up air under pressure (even though air
supply
is cut-off)
may cause gaskets and/or
particles
of dirt to
become airborne
and an
increase
in sound
level when this device and/or any component part
is removed from the equipment arrangement.
• Personal eye and ear protection must be worn and
care
taken
to
avoid possible injury
when performing
