e. Tie a plumb bob or any heavyobject to end of a long string.Hold other end of string atintersection of side plate andextension plate behind driver’shatch (M577A2 and M1068only).f. If plumb line aligns with thirdtrack shroud cover screw, slopeis about 30%. This ismaximum slope. Entry is OKat crawl speed. If plumb linefalls to rear of screw, slope isless than 30% and entry isOK (M577A2 and M1068only).7. Determine slopeTM 9-2350-261-10percentage bymeasurement as follows:a.b.c.Height of slope. Measurevertically from top of slope tobase of slope.Length of slope’s base.Measure horizontally frombase of slope to point whereslope starts.Divide base into height thenmultiply answer by 100 toobtain slope percentage.GO TO NEXT PAGEChange 32-293
