I am remembering that it is recommended to use the factory hydraulic filter, while if you search on the word filter in this forum you can find a Wix cross to the oil filter. Your parts dealer can then cross the Wix to your Purolator preference.
I have also read about removing a bolt to allow air out, when your filling the hydraulic fluid. Read your manual section on maintenance, you may have a screen to remove and clean.
Good Luck,
Jim
