The hoist LED will display a flashing orange and the LCD will indicate “Charging”
Has this resolved your issue?(Required)
Traverse the hoist into the charging dock to test this function.
Check that the charging unit is turned on at the power supply.

The charging unit will display a steady green LED when turned on, or a flashing orange light when the hoist is charging.


If the unit flashes orange and shows the hoist is charging, allow to charge for 20 minutes and retest the function.
Has this resolved your issue?(Required)
Inspect the full length of the cable for damage such as exposed wires, cuts and burns.
Replace Charging Dock Assembly
See Spare Parts Manual for details on replacement parts.
Retest the function by operating the hand controls
See Charging Dock Testing Guide – Document No. 990SD-03

Has this resolved your issue?(Required)
Visual damage includes exposed wires, cuts or burns
Replace Charging Beak Assembly
See Spare Parts Manual for details on replacement parts.
Retest the function by operating the hand controls
Has this resolved your issue?(Required)
Allow the hoist to charge for 20 minutes

20 minutes will allow the hoist to charge sufficiently to power up.

After 20 minutes, retest the function by operating the hand controls.
