REPLACING AIR BREATHER ELEMENT
Immediately after engine operation, the oil is hot and it may cause in burns. Wait until the oil temperature cools
down before attempting to change the element.
• To keep the hydraulic oil clean and to extend the service life of the hydraulic components, replace the filter
element at regular intervals.
• Every 1000 hours replacement is a rough guideline. If the machine is operated in very sandy and dusty
conditions, replace the oil filter earlier than the specified interval.
