NOTES:

Capacities shown in "Black" are 100% of main cylinder hydraulic capability; capacities shown in "Red" are 87% of hydraulic capacity.

Notice that some of the lifts in "Red" are higher than main only, since the stick has mechanical advantage and the limiting lift is the

main relief.

Note: Deduct grapple weight for payload
