Slowly move HOIST WINCH operating lever (Figure 2, Item 1) to INHAUL position to take slack out
of cables.

Start payout of main winch cable slowly. Fast initial payout can cause the cable to unspool.
Failure to comply may result in damage to equipment.

CAUTION
Use disabled vehicle tow cables as a sling leg for recovery operation (FM 4-30.31
(WP 0131)). The use of M88A1 tow cables does not allow accurate sling leg force
calculation. Improper angle will give false-use-of-shackle estimation. Failure to comply may
result in damage to equipment.
