TOWING MACHINE OPERATION HEAVE MODE NORMAL SPEED
1.
Perform the Towing Machine Operation System Setup procedure in this work package.
2.
Verify that the SYSTEM READY indicator (figure 11, item 1) on the towing machine operator control panel (figure 11,
item 2) is illuminated.
3.
Verify that the SYSTEM PRESSURE gauge (figure 11, item 3) indicates that the towing machine hydraulic system is
supplying hydraulic fluid to the system.
4.
Place the local or remote switch (figure 11, item 4) in the local position by pushing it down fully to the NORMAL
OPERATION AT CONSOLE mode.
5.
Ensure that the directional control lever (figure 11, item 5) is in the NEUTRAL position. The NEUTRAL position is
centered between the PAYOUT and HEAVE positions.
NOTE
Shifting the two-speed valve must always be done with the control lever in the NEUTRAL posi-
tion. The knob may be shifted at any time, but the control circuit will prevent a speed range shift
while the towing machine is moving. Once the towing machine stops, the speed range shift will
automatically take place, corresponding with the current position of the speed range knob.
6.
Place the speed range selector (figure 11, item 6) in the NORMAL OPERATION mode by pushing it down fully.
! CAUTION
The speed of the LT must be carefully controlled while heaving in the line. The LT could over-
power the towing machine motor, causing severe damage to the motor.
NOTE
The towing machine will operate at a speed proportional to the lever movement.
7.
Place the directional control lever (figure 11, item 5) in the HEAVE position. The towing machine will operate at a
speed proportional to the lever movement.
