Roll Back Hose Inspection
(50 Hour Intervals)
With the transfer carriage fully forward,
check the roll back hoses and hose
protector sleeves for wear.
• Inspect all hoses (1) for wear. Replace any hoses when the steel braids are
first visible.
• Hoses with protective sleeves (2), check the sleeves for worn areas. If a
worn area is detected, rotate the sleeve to a new wear area. If excessively
worn, replace the protective sleeve with a new sleeve.
