ORGANIZATIONAL MAINTENANCE INSTRUCTIONS
Section I. SERVICE UPON RECEIPT OF MATERIEL
4-1. Inspecting and Servicing the Equipment
a.
Inspection.
(1)
Inspect for missing components and loose or missing parts and hardware.
(2)
Inspect for dents, cracks, and other damage that may have occurred during shipment.
(3)

4-2. Unloading the Equipment
The rear winch boom on the transporter can be used to unload the boat cradle.
a.
Prepare the transporter for unloading the cradle.
(1)
Apply the transporter service brakes, place transmission in neutral position, lock the service
brakes, depress the control lever to enage the boom winch drive, and release the clutch pedal.
(2)
Set the hand throttle so the engine operates at 1,800 RPM.
(3)
Engage the hydraulic control lever, (fig. 2-4) to disengage the boom-point lock pin.
b.
Push the boom and winch Hydraulic control levers to elevated the boom to an angle of about 20
degrees and pay out the boom cable. Continue to slowly pay out the boom cable so that boat cradle rolls
downward over the rear support inboard rollers.
c.
After the center of gravity passes the inboard rollers, adjust the boom elevation as needed to maintain
alignment with the boat cradle. Continue to pay out the boom cable and allow the boat cradle to descent
toward the hardstand.
d.
Allow the end of the boat cradle to come to rest on the hardstand. Use an assistant to pay out the
boom cable as needed. Release the brake and slowly move the transporter forward as the assistant pays out
the boom cable, so that the transporter rolls beneath the boat cradle until the forward cradle stop pins (12, fig.1-
1) engage the stop brackets on the rear support inboard rollers (fig. 2-4).
e.
The assistant will then elevate the boom to a vertical position and rewind the boom cable slightly, so
that the end of the boat cradle is raised enough to allow the stop pins to clear the stop brackets.
f.
Move the transporter forward two feet, place in neutral and lock brakes then extend the boom to
maximum, so the end of cradle will clear the transporter.
