NOTE: Since track tension and track alignment are interrelated, always check both even if only one adjustment seems necessary
! WARNING
If jam nuts are not tightened properly, the adjusting bolts could loosen causing the track to become extremely loose and, under some operating conditions, allow the idler wheels to climb over the track lugs forcing the track against the tunnel causing the track to "lock If track "locks" during operation, severe personal injury could result
