Description

State the condition of the PTW throttle.

(OECD RS9/TEG/ 151 definition)

The following procedures may be used as a guide to determine throttle/drum condition:

Proper evaluation of the throttle assembly is achieved by performing an initial evaluation of the throttle control.

Firmly grasp the drum and rotate the drum counterclockwise (i.e. apply the throttle).

If the drum returns back to its normal condition then the drum is considered to be normal and there is no abnormal conditions in the throttle system.

Code all cables, slides and springs as being in normal operating condition.

If the drum does not return to its normal position then there is an abnormal condition in the throttle system that will require further investigation.
