Name the system affected
Tell us whether the problem is with driving the truck, operating the aerial equipment or both. Name the function that stopped working and tell us which other functions still respond.
Bring both sets of equipment details
The truck chassis details may not identify the aerial equipment. Have the aerial manufacturer, model and serial number ready if available, along with any recent changes or earlier repair work.
Ask about testing before booking
If your organization needs a particular inspection, dielectric test, certification, or service record, discuss that before booking. Do not assume a repair appointment includes separate testing or certification.
