Maintenance and Repair
Important:
Inspections are recommended, as needed, based upon volume of
traffic and impact history. Visual Drive-By Inspections are recommended at least
once a month. Walk-Up Inspections are recommended at least once a year.
Visual Drive-By Inspection
1) Encountering a system with the Hit Indicator in the vertical position mandates inspection
of the system. A walk-up inspection will be necessary.
2) Inspect the system in accordance with the QuadGuard
®
Elite M10 Wide Maintenance Flow
Chart (p. 40).
Caution:
It is important to inspect a system after it has been impacted even if it
appears to be self-restored and fully maintained. In particular, check the Fender
Panels/Diaphragm attachment bolts to be sure none have failed.
3) Be sure the Nose assembly is in place and in good condition.
4) Note the location and condition of the QuadGuard
®
Elite M10 Wide and the date of visual
drive-by inspection.
Walk-Up Inspection
Warning:
A system that has been impacted can store energy in collapsed
Cylinders and may spring back unexpectedly causing possible serious injury. Use
caution when inspecting, disassembling or restoring systems that are collapsed or
compressed by any amount.
