Cleaning the brake lights
Scraping and hauling dirt at the worksite is a messy job. That means you operators have to make it a point to eyeball the 621G scraper’s brake lights in the back of the vehicle during PMCS.
Dirt and mud get thrown onto the brake light’s lens cap because of the forward movement of the vehicle’s rear wheel assemblies. That dirt and mud will cover up the vehicle’s rear brake lights. That’s a safety problem if another vehicle is operating behind you and your scraper comes to quick stop!
So make it a point to clean off the rear brake lights with a hose or a clean rag before and after the day’s run.
