3. 6 AUXILIARY HYDRAULICS
To operate an attachment such as a grapple fork the Left
Hand Control Lever will be used. Push right of neutral on
the Auxiliary Hydraulic Control Switch to open the
grapple (Fig. 3.6J).
To close the grapple (Fig. 3.6K), push left of neutral on the
Auxiliary Hydraulic Control Switch, or push down on the
toe of the auxiliary pedal if so equipped. The lift arm and
bucket pedals can be used to raise and tilt the grapple as

To operate an attachment which requires a constant flow of
oil, a toggle switch on the L.H. instrument panel (Fig.
3.6L) should be placed in the “ON” position.
When the auxiliary circuit is not in use switch to the
“OFF” position. Otherwise starting the loader may be
difficult or impossible and damage to the starter may
occur.
Return the auxiliary
control to neutral when
not in use otherwise
starting may be
impossible and damage
to the starter may occur.
