occur. Unexpected movement of the machine can cause personal injury
or death.
To prevent injury or death, never work under a machine while a test is
being performed.
Prevent sparks near the batteries. Sparks could cause vapors to
explode. Do not allow jumper cable ends to contact each other or the
engine.
To avoid personal injury from electrical shock, ensure that the negative
battery cable is disconnected first.
Note: It is recommended the technician read these instructions thoroughly prior to performing this
procedure.
Note: The oil supply tube is a ONE TIME USE ONLY item and must be replaced if damaged or
removed. The T-fitting and adapter fitting are reusable and to be installed per these instructions the first
time.
