Before lifting the load, crank the hand winch clockwise as needed to remove excess slack in the
wire rope and to verify that it is not loose or tangled in any way. Make sure the load is ready for
lifting and that it will not slide or swing once tension is applied to the wire rope. Also make sure
that the load will not encounter any obstructions on the way up to its installation point.
To raise the load, crank the winch in the clockwise direction. You should hear audible “clicks” as
the winch gradually lifts the load, indicating that the automatic brake is properly engaged. When
the load is only a few inches off the ground, stop cranking the winch and verify that the
automatic brake will hold the load. Once you have verified that the brake is functioning, slowly
continue to crank the winch until the load has reached the desired height. Take care not to
shake the Ladder Lift by aggressively cranking on the winch.
Note: The hand winch requires a minimum load of 50 lbs [23 kg] for the automatic braking
feature to work correctly; see the winch manufacturer's instructions (provided) for details.
If winching becomes significantly more difficult at any time while you are lifting the load,
discontinue winching. Make sure there are no obstructions to the load, that you have not
exceeded the Maximum Lift Height (see SPECIFICATIONS) and that the wire rope has not
become snagged anywhere. Identify the source of the resistance and resolve it before
continuing, in order to prevent undue stress on the Ladder Lift units, wire rope or load.
WARNING: Never force winch to overcome obstacles or snagged rope. Doing so
could result in personal injury, or damage to Ladder Lift or load.
If a rotating load would strike anything on the way up to the desired height--especially a work
support structure, the building or the Ladder Lift itself--use a guide rope or similar means to
restrain the load from rotating. Do not allow anyone to stand under the load while using such a
restraint; it should be sufficiently long for a person to stand safely out of the way while using it.
WARNING: Never leave suspended load unattended.

To lower a load, follow the same safety guidelines as when raising a load (above), and slowly
crank the hand winch counter-clockwise until the load rests securely on the ground or a stable
support. Follow the same procedure to lower an empty lifting hook.

If there is a load attached to the Ladder Lift, first remove the load. Then reverse the ASSEMBLY
instructions, as follows: Carefully remove the Ladder Lift from the building and set it on the
ground.
1 Once the Ladder Lift is on the ground, remove the cotterless hitch pins and unhook the
pulley and winch units from the ladder. Reinstall the cotterless hitch pins once both units are
free from the ladder. Retract the wire rope until the pulley and winch units are touching one
another, while minimizing contact between the wire rope and the ground. The Ladder Lift is now
ready for storage.
Store the Ladder Lift in a dry location and, if necessary, cover it to prevent dirt, water or other
contaminants from damaging the wire rope.

For extension ladders, it is acceptable to use the ladder’s pulley system to retract the ladder first.
