2-11 Prestart procedures
NOTE
These procedures start with the workboat in the water and secured
to side of the barge with four lines using the small workboat cleats
on the forward two-thirds of the barge on either side. This is the
area with the vertical fenders. Procedures for launching from and
returning the boat to its storage cradle on the deckhouse top are
provided in paragraph 2-17.
a.
Make an overall visual check of workboat's condition. Check boat's hull and installed equipment, such as running
lights and searchlight, and also make sure it is properly secured with lines and bumpers.
b.
Open cabin and make sure master switch is OFF. Obtain engine hatch tool from under operator's seat (Figure 2-
8).
c.
If necessary, move messenger line reel unit (see Figure 2-9) as far forward as possible. Pull pins on sliding
tracks on each side of unit, shove unit forward against the stops and replace pins.
d.
Using engine hatch tool, rotate lock nuts on each corner one half turn counterclockwise and slowly open engine
compartment (aft deck closure). Escaping air may indicate that water is entering engine compartment and forcing
air out.
e.
Check engine compartments to make sure there are no diesel fuel, water, oil or hydraulic fluid leaks. Tighten
filters and fittings or take other corrective action as necessary.
