Instruction Manual - RIV 938S
OPERATORS
The tool is designed to be used by one operator only.
Tool operators must satisfy the requirements stated hereafter (or they must be informed and trained accordingly).
They must be aware of the manual herein and of all information relevant to safety:
• They must have some general and technical education, to a sufficient level to be able to understand the manual
and to interpret the drawings and the diagrams correctly.
• They must be acquainted with the safety rules, and with the industrial-safety and technical instructions.
• They must have an overall knowledge of the line and of the factory in which the tool is installed.
• They must know how to act in case of emergency, where to find the individual protection means and how to use
them correctly.
Together with the above-mentioned requirements, the service technicians must also have appropriate technical
training.
MOTOR SCREWING ROTATES NONSTOP
When the rotating pin (6 Part Number 4151500) is broken and you replace it, the motor may rotate
continuously, which means that the shaft (13 Part Number 3761300) is too long; in this case it will have to
be shortened by a few tenths to obtain the closure of the ball (14 Part Number 3096900).
MOTOR UNSCREWING DOES NOT ROTATE
Unlike the situation above, the shaft is too short and it has to be replaced with a new one, fitting it on
the rotating pin (you will have to shorten it) in order to obtain the closure of the ball (14 Part Number
3096900).
