Operation & Maintenance Instruction
•
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
any work on this device and/or component part.
