3. To prevent contamination of hydraulic system during lift cylinder removal,
thoroughly clean exterior of cylinder and fittings.
Make sure that the cutting units are fully lowered before loosening
hydraulic lines from lift cylinders. If cutting units are not fully
lowered as hydraulic lines are loosened, cutting units may drop
unexpectedly.
Note: To ease installation, label the hydraulic hoses to show their correct
position on the lift cylinder.
4. Disconnect the hydraulic hoses from lift cylinder and plug hydraulic hoses to
prevent contamination.
5. Remove front lift cylinder from the frame and lift arm using
guide.
6. If hydraulic fittings are to be removed from lift cylinder, mark fitting orientation
to allow correct assembly. Remove fittings from the cylinder and discard
O−rings.
1. If fittings were removed from lift cylinder, lubricate and place new O−rings
onto fittings. Install fittings into cylinder port openings using marks made
