Section I. STRAIGHT-EDGE FLOOR SCRAPER
All dimensions given in Section I are in standard units.
a. After rustproofing a vehicle, the rustproofing compound may drip onto the shop floor creating "pancakes" of
compound. The process of removing these can be time consuming, even with powerwash equipment and detergents.
The most effective way to clean the shop floor is to scrape, then wash the surface down.
b. The straight-edge floor scraper can also be used on certain vehicles, such as the 5-Ton Tractor Truck. This
vehicle has a hitch platform on the underside which may require scraping to ensure proper function.
c. A 1-inch putty knife can be found in the standard shop tool kit and a 4-inch putty knife can be obtained
from the supply activity. These tools may serve as a suitable alternative or as a supplement to the fabricated scraper.
