Notes For Use Of Throttle; Idle Speed Stepper Motor; Working Principle Of Idle Speed Stepper Motor; Appearance Of Idle Speed Stepper Motor - Benelli TNT125 Maintenance Manual

Always open the valve plate using throttle wire.

Do not put tools or other items inside the throttle

body to maintain the opening of valve plate. This
may result in deformation of valve plate or
scratching of inner wall of throttle body. Such
damage may cause the valve plate to be too easily
opened or difficultly.

Notes for Use of Throttle

Notes
Please: be caureful to install the connectors of all throttle
body
Please: avoid any liquid from entering throttle body
Please: take one throttle body from the part tray and
install it
Please: return the dropped, damaged or suspected parts
and label them to describe the existing problems (only for
three packs of components)
Do not: use any dropped or squeezed parts
Do not: store or transport it near salt water in unprotected
conditions
Do not: expose it to the environment before the
completion of assembly (such as humid environment)
Do not: test it using non-system operating voltage
Do not: use extra clamps

come into contact with other parts.

Idle speed stepper motor

Working Principle of Idle speed stepper motor

The function of idle speed control valve is to control the flow area of
bypass air passage of throttle body, so as to adjust the air volume of engine
and control the idle speed of engine.
