NOTE: Line up the Fill/Drain Plug with the upper cutout hole (A). Let hoist sit idle for 20 minutes for an accurate reading. Ensure hoist is level and oil is within 21°C ±11°C (70°F ±20°F). If oil level is not visible in sight glass, the hoist may be underfilled. Oil escaping from vent plug is an indication the hoist may be overfilled. If hoist is over filled move the Fill/Drain Plug to the lower cutout hole (B) and drain until oil level falls within the sight glass. 92

Thoroughly coat 250 hours or 3 monthsSpray on

NOTE: Lubricate more frequently than interval indicated in table if environmental conditions and/or operating conditions necessitate.

NOTE:

Check fluid level every daily.

•Use sight gauge on side of tank, with boom down and all outrigger cylinders retracted.

•Drain and refill as necessary

• Environmental and other conditions can dramatically affect the condition of hydraulic oil and filters. Therefore, specific intervals for servicing/changing hydraulic oil, filters and hydraulic tank breathers cannot be set. However, it is imperative for the continued satisfactory performance of cranes that inspections be performed on the basis of how and where each crane is used. Air borne and ingested contaminants can significantly reduce the life of oil and the condition of hydraulic oil filters and tank breathers.

•Under normal operating conditions, it is recommended that hydraulic oil, filters and breathers be inspected and oils sampled at least every 3 to 6 months and more frequently for severe operating conditions. The inspections should be for air borne and/or ingested particles and water that deteriorate and contaminate the oil (e.g., oil appears “milky” or no longer has a transparent clear to amber color). The return filter by-pass indicator should be observed daily to determine if contaminant content may be high. If the indicator reaches the red zone or indicates a by-pass condition, the hydraulic oil must be sampled. The hydraulic tank breather should also be inspected to assure that it is not restricting air flow into and out of the reservoir.

•To inspect hydraulic oil, fill a small glass container with a sample of reservoir oil and another glass container with fresh oil. Let the samples stand, undisturbed, for one to two hours and then compare the samples. If the reservoir oil is heavily contaminated with water the sample will appear "milky" with only a small layer of transparent oil on top. If the "milky” appearance was due to air foaming, it will dissipate and the oil should closely match the fresh oil. Should you have any questions, please contact your local authorized Manitowoc distibutor.

•The hydraulic oil shall meet or exceed ISO #4406 class 19/17/14 cleanliness level.
