As each control lever is moved forward or backward
from center (or neutral) position, oil flows to cylinder or
motor controlling a function. Component (boom,
grapple, etc.) starts to move. Component moves faster
as control lever is moved further forward or backward.
Holding lever in forward or backward position will hold
that function at a given rate of speed. To slow
movement down, gradually move lever toward neutral
position. That position is maintained until control lever
is moved again.
Feathering the controls is a technique that will
increase loading output and make operating machine
easier. When starting any motion of machine, move
control slightly from neutral until it starts to move, then
smoothly move control to increase motion to desired
speed. Do the same when stopping a motion.
There is no fixed feathering position for any control.
Operator will discover how far to move each control for
maximum effort with practice.
After the operator is used to the responses from
movement of the control levers, two or more
components (such as booms and grapple) may be
functional at the same time. Even slight movement of
two or more controls at the same time allows oil flow to
each function.
Always heel load on opposite side of boom from cab to
help prevent load from coming into contact with cab at
any time.
Another operating technique involves the "end of travel"
of cylinders. Gradually return control lever to neutral or
center position, whenever a cylinder
approaches end of travel. This will prevent
overheating of system's components and save fuel.
Additional holding, lifting, or grabbing power will not
occur by holding a control lever in far forward or
backward position.
It is better to allow component (boom, grapple, etc.)
to stop by returning lever to neutral before cylinder has
reached end of travel. Get to know end of travel of all
cylinders and use lever to stop function rather than
waiting for end of cylinder travel.
Practicing these techniques will result in smooth
working cycles with minimum effort. Each machine has
a definite rhythm of operation. Feathering controls and
overlapping machine motions are techniques to help
find this rhythm and take advantage of it.

Select an operating site for loading and unloading
positions within machine's reach and capacities. Keep
in mind that short boom travel and swing are most
efficient.
