R EMOVAL
1. Elevate and block the elevating assembly (See Figure 2-2).
2. Open emergency lowering valve to be sure all pressure is out of the lift cylinder.
3. Remove and cap both hoses and fittings.
4. Remove the down valve and cable assembly.
5. Support the lift cylinder with a suitable lifting device to prevent falling.
6. Remove the retaining bolts from the upper and lower pivot pins.
7. Drive out the pivot pins, upper one first, then the lower one.

I NSTALLATION
NOTE: Before installing the cylinder, check the pins and bearings for excessive wear. Replace if necessary.
1. Using a suitable lifting device, lower the cylinder into the elevating assembly from the front. DO NOT
sling the cylinder by the rod end pivot, this will cause the cylinder to extend when hoisted.
2. Align the pivots and install the pivot pins, lower one first, then the upper one.
3. Install the retaining bolts into the pivot pins.
4. Install the down valve and cable assembly. Adjust the cable to stop on the collar of the cable jacket,
before the down valve reaches the full extent of its pull. The down valve may leak if the cable is allowed
to pull the spool of the valve beyond its limit.
5. Install the hoses.
6. Lift and lower the machine for several cycles to work out the air. Check for leaks, repair as necessary.
