4225-50, S.6

 WARNING:

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.

•

Portions weigh in excess of 30 pounds. Use care

when lifting and hauling portions to preclude injury.

•

Due to the possibility of exhausting air, and high

decibel levels of noise associated with it, from the
device during testing, it is recommended that sufficient

hearing and eye protection be used. This is intended

to minimize the possibilities of hearing and eye injury
to the operator or persons near the test rack.

•

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 component

parts to avoid any possible injury to the eyes.

•

The use of solvents and 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 ensure that

vehicle movement will not occur which could result in

injury to personnel and/or damage to equipment.
