6. Lower the platform, then raise it to bed 
    level. The outboard edge of platform should 
    be level or up to 1” maximum above bed 
    level (FIG. 52-3).
4. Compare measurement “B” (FIG. 
52-1) with the distances and grinding 
depths in TABLE 52-1. For example: 
If measurement “B” (FIG. 52-1) is 3” 
above bed level and you want to lower 
the outboard edge of platform to 1” 
above bed level, grind 1/8” from each 
platform stop (TABLE 52-1).
5. Grind metal from platform stops (FIG. 
52-2) to lower outboard edge of plat-
form to correct position.
