EXTERNAL AIR TRANSPORT BY CH-47 HELICOPTER - CONTINUED
MACHINE DISASSEMBLY AND SECTIONALIZATION - CONTINUED
Use extreme caution when driving sectionalized tractor with stability skids and no ROPS/FOPS.
Use first gear forward and low idle ONLY.
Ground guide or ground safety officer assistance is required to monitor path in front of front stabil-
ity skid, to avoid obstacles and direct tractor operation.
Do NOT use differential lock in skid steer mode.
Once sectionalized, conventional steering will not function.
Using low idle and first gear ONLY, drive tractor forward and separate from scraper:
Steer using skid steer control: push control to right to turn right. Pull control to left to turn left.
Drive tractor forward a minimum of 50 ft (15.3 m), to separate tractor from scraper and to allow sufficient
clearance for CH-47 lift.
Reinstall draft arm pins and hardware in scraper bowl.
