OUTRIGGER CIRCUITS (OPTIONAL)
To raise and lower the outriggers two control valves
are located to the right of the operator’s seat. One
valve controls the right and one controls the left.
Pushing forward on the levers will lower the out-
riggers and pulling back on the levers will raise them.
Oil for the outrigger valves comes from the power-
beyond port of the main control valve bank.
When making a lift, the outriggers should be de-
pressed enough to lift the front tires clear of the
working surface.
