Beginning Operation
• Turn pump switch to the “on” position
while engine is idling. (Red light will
indicate that pump is on).
IMPORTANT: In cold weather, allow the
engine to idle for 5-10 minutes with the
pump on before operating the arms.
This will allow the oil to warm up and
flow more freely. Neglecting to do this
may cause hydraulic pump failure.
Loading
• Back truck against bale with arms
wide apart and tilted slightly upward.
• Close the arms firmly against the bale.
• Lift the bale onto the truck.
• Release the bale and repeat the
operation for the second bale.
IMPORTANT: When hauling one bale,
make sure it is resting on the bed.
When hauling two bales make sure the
second bale is as far forward as it will
go (Fig. 1). Carrying a bale behind the
bed, as shown in Fig 2, places
excessive stress on the cylinder,
linkage, and pins.
NOTE: Spinners may be necessary to grip
the front bale for unloading.
Unloading
• To unload, do the reverse of the load-
ing operation.
Unrolling
NOTE: Risers and spinners must be installed
to unroll bales.
• Position the arms over the bale so the
spinner is at the center of the bale.
• Close the arms and pick up the bale.
• To unroll, lower the bale to the ground.
• Turn the pump off and push the
FLOAT switch on the hand control.
• Drive forward slowly. Bale will gradu-
ally unroll.
• When finished, touch FLOAT or an
other function to disengage.
CAUTION: Failure to engage FLOAT
function while unrolling a bale may
damage lift cylinder rod.
Storing the Arms
• Close arms partially and lay them on
bed.
• Open arms until they are flush with
sides of bed. They now function with
the dummy arms as the bed’s side
rails.
Turning the System Off
• Turn the pump off and release pres-
sure in the system by stroking one of
the function switches when flatbed is
not in use.
CAUTION: Operating truck at road speeds,
or above 2,000 RPM, with pump engaged,
may cause hydraulic pump failure.
