(1)
Open valve SD3 (Figure 15-9).
(2)
Obtain BAND BRAKE PUMP HANDLE from stowed position and insert in pump extension.
CAUTION
While pumping, do not exceed 4,000 psi as shown on BAND BRAKE PRESSURE
GAUGE.
(3)
Pump until band brake piston enters cylinder and band is tight on the brake drum.
(4)
Position valve SD3 in neutral position (midway between OPEN and CLOSE position) to lock the
cylinder in the set position.
(5)
Remove pump handle and return to stowed position.
c.
Make sure switchboard circuit breaker P12 is closed (ON).

If system has not been operated for several days, allow hydraulic oil to circulate at low pressure
to remove entrapped air.
Barge 1 - Allow pumps to run with winch control and levelwind control levers in neutral position.
Barges 2 and 3 - Allow pumps to run with disc brake control OFF and winch and levelwind control
in neutral.
(3)
Check for oil leaks and tighten fittings if necessary.
(4)
Make sure charge pump pressure gauge on hydraulic power unit reads 250 psi.
NOTE
On Barge 1, levelwind is used during deployment and retrieval. On Barges 2 and 3,
levelwind is allowed to freewheel during deployment.
f.
On Barges 2 and 3, turn valve SD5 ON (Figure 15-10).
