TOWING MACHINE TOWING ON THE MECHANICAL DOG
1.
Prepare the towing machine for operation under usual conditions (WP 0039 00, volume 1) and rig the tow (WP 0095 00,
volume 1), including establishing the desired scope (TM 55-1900-232-10).
! CAUTION
Never engage the mechanical dog while a drum is rotating in the payout direction. Doing so will
damage the mechanical dog and the towing machine.
NOTE
The operator must observe the tow at all times while towing on the mechanical dog. All emer-
gency release features of the machine are disabled when the mechanical dog is engaged. In order
to pay- out or pull in, the towing machine must first be set to HEAVE mode and the mechanical
dog disengaged.
2.
Remove the quick release pin (figure 1, item 1).
3.
Engage the mechanical dog (figure 1, item 2) in the ratchet teeth (figure 1, item 3).
4.
Secure the towing machine and the towing machine hydraulic system (WP 0039 00, volume 1).
5.
Loosen the clutch brake handwheel (figure 2, item 1) slowly until the drum turns slightly and all of the load is trans-
ferred to the mechanical dog.
6.
Tighten the clutch brake handwheel (figure 2, item 1).
7.
Install the quick release pin (figure 1, item 1).
