Replacing the Lift Cylinder

1. Lower the cutting unit to the ground.
Stop the engine.
2. Clean in accordance with Working
Methods on page 78.
3. Remove the rear cylindrical bolt. Two
washers are released. If it becomes
tight, place the hydraulic lifting lever in
the lowering position and twist the drive
disk on the lever housing's shaft with an
adjustable wrench or similar tool.
4. Hold the angle nipples with a 17 mm
wrench and loosen the hydraulic
connections from the cylinder. A small
amount of oil will leak out.
5. Remove the front cylindrical bolt. Two washers are released.
6. Attach the hydraulic cylinder to the forward mounting. A washer is placed on each side of the cylinder
ear in the fork. Secure the cylinder bolt.
7. Connect the hydraulic connectors.
Counter the angled nipples. Twist the
hoses so that they do not chafe against
any sharp edges. The front hose on the
cylinder shall run to the upper connector
on the valve block.
8. Attach the hydraulic cylinder to the rear mounting. A washer is placed on each side of the cylinder ear
in the fork. Secure the cylinder bolt.
9. Remove the transmission cover and top up with transmission oil. Be observant when running the
engine and top up so that the tank is not emptied.

of excess air.
