2.1.2 Emergency Operation
2.1.2.1
In case of power failure, disconnect all power sources supplied to the winch.

Rotate the locking pawl handle down so the locking pawl is free to engage thus dogging the
winch down (see fig. 3b).
2.1.2.3
Make sure safety precautions have been taken to secure the load and keep unnecessary
personnel away from the winch while operating in manual mode.
2.1.2.4
Remove the rubber cover from the front of the winch.

Remove the Hex Jam Lock Nut (see fig. 4) from the Emergency Ratchet Add-on.

2.1.2.7
Replace the Hex Jam Lock Nut on the outside of the winch in the Engaged Position.
2.1.2.8
Disengage the motor brake by turning the lever located on the outside of the brake 90
degrees. The locking pawl should now be holding the load applied to the winch.
2.1.2.9
While maintaining control of the brake release lever and manual crank, rotate the locking
pawl handle up relieving the locking dog engagement (see fig. 3a). The winch should now be
ready to be operated manually. It is recommended to have more than one person to operate
the winch in manual mode.
2.1.2.10
Using a 15/16” ratchet, rotate the Emergency Ratchet Add-on until the tension on the wire
rope reaches the desired level.
2.1.2.11
Once tensioning has been acheived, the locking pawl should be reengaged dogging the load
down.
2.1.2.12
After all loads have been removed from the winch, remove the Emergency Ratchet Add-on
and store in the Stowed Position.
WARNING
Manual operation of an electric winch while under load is extremely dangerous and should
only be performed in emergency situations. The extreme high tensions that are common in
winch applications should not be underestimated.
To reduce the potential of electric shock, lock out and tag out procedures should be followed
before initiating any type of manual operation of the winch
