Precautions: 00-2
Eye Protection Caution
WARNING
!
Approved safety glasses and gloves should
be worn when performing this procedure to
reduce the chance of personal injury.
Foam Sound Deadeners Caution
WARNING
!
Foam sound deadeners must be removed
from areas within 152.4 mm (6 in) of where
flame is to be used for body repairs. When
reinstalling foam sound deadeners, avoid
inhaling fumes as bodily injury may result.
Gasoline/Gasoline Vapors Caution
WARNING
!
Gasoline or gasoline vapors are highly
flammable. A fire could occur if an ignition
source is present. Never drain or store
gasoline or diesel fuel in an open container,
due to the possibility of fire or explosion.
Have a dry chemical (Class B) fire
extinguisher nearby.
Glass and Sheet Metal Handling Caution
WARNING
!
When working with any type of glass or sheet
metal with exposed or rough edges, wear
approved safety glasses and gloves in order
to reduce the chance of personal injury.
Moving Parts and Hot Surfaces Caution
WARNING
!
Avoid contact with moving parts and hot
surfaces while working around a running
engine in order to prevent physical injury.
Protective Goggles and Glove Caution
WARNING
!
Always wear protective goggles and gloves
when removing exhaust parts as falling rust
and sharp edges from worn exhaust
components could result in serious personal
injury.
Road Test Caution
WARNING
!
Road test a vehicle under safe conditions
and while obeying all traffic laws. Do not
attempt any maneuvers that could jeopardize
vehicle control. Failure to adhere to these
precautions could lead to serious personal
injury and vehicle damage.
Work Stall Test Caution
WARNING
!
One or more of the following guidelines may
apply when performing specific required
tests in the work stall:
• When a test requires spinning the drive
wheels with the vehicle jacked up, adhere
to the following precautions:
– Do not exceed 56 km/h (35 mph) when
spinning one drive wheel with the other
drive wheel stopped. This limit is
necessary because the speedometer
indicates only one-half the actual
vehicle speed under these conditions.
Personal injury may result from
excessive wheel spinning.
– If all of the drive wheels are spinning at
the same speed, do not exceed 112 km/h
(70 mph). Personal injury may result
from excessive wheel spinning.
– All persons should stay clear of the
rotating components and the balance
weight areas in order to avoid possible
personal injury.
– When running an engine in the repair
stall for an extended period of time, use
care not to overheat the engine and the
transmission.
• When a test requires jacking up the vehicle
and running with the wheels and brake
rotors removed, adhere to the following
precautions:
– Support the suspension at normal ride
height.
– Do not apply the brake with the brake
rotors removed.
– Do not place the transmission in PARK
with the drive axles spinning.
– Turn Off the ignition in order to stop the
powertrain components from spinning.
• When running an engine in the work stall,
use the exhaust removal system to prevent
breathing dangerous gases.
