The hydraulic pump normally does not require regular fluid
changes. The system filter should be changed after 250
hours of operation or annual intervals. The fluid and filter
should be changed and system cleaned if the fluid becomes
contaminated with foreign matter (water, dirt, grease, etc.)
or if the fluid has been subjected to temperature levels greater
than the maximum recommended.
There is a greaseable bearing on each side of the main jack
shaft on the main hydraulic feed housing. Grease periodically
(see section 5.8).
