ASSEMBLY
1) Open the shipping container and remove all materials for restraining or protecting the Ladder
Lift. Save the container for use whenever the Ladder Lift is transported.
2) Install the handle on the hand winch, as follows: The handle has been removed for shipping
and replaced temporarily by a 5/8-11 hex nut and washer, to maintain tension on the winch
during transport. Remove the temporary nut and washer; they are no longer needed. Install
the handle and all original hardware as shown in the illustration for winch model DLB800A in
the winch manufacturer’s instructions (provided). However, note that spring E has been
replaced by a polyethylene spacer.
3) Select a ladder that conforms to all the Ladder Requirements stipulated in SPECIFICATIONS.
4) Attach the Ladder Lift's winch and pulley units to the ladder, as follows: Slacken the wire
rope on the winch unit (see OPERATION: T O L OWER A L OAD ). Remove the cotterless hitch pins
from each rung support. Then hook the pulley unit on the top load-bearing rung of the ladder
and hook the winch unit a few rungs above the base of the ladder, at a comfortable height for
using the hand winch (see OPERATING FEATURES for proper orientation of units). Reinsert
the cotterless hitch pins to secure the winch and pulley units to the ladder.
5) Erect the Ladder Lift, as follows: To prevent the lifting hook from swinging and hitting
something inadvertently, take up most of the slack in the wire rope before erecting the
Ladder Lift (see OPERATION: T
O
R
AISE THE
L
OAD
). Two people are normally required to
maintain stability while erecting the Ladder Lift, especially with longer ladders. Lean the
ladder against the building where you intend to use the Ladder Lift. For extension ladders,
slacken the wire rope and extend the ladder to its final erected length, using the ladder pulley
as necessary.
WARNING: Never place base of ladder more than 1/4 of its length from building.
When the Ladder Lift is in its final position, the distance from the base of the ladder to the
building should be 1/4 the length of the extended ladder (for example, the base of a 24' [731
cm] extended length ladder should be 6' [182 cm] from the building). For maximum stability,
the operator should locate the base of the ladder out as far as possible without exceeding this
relationship. If the ladder were positioned past 1/4 of its extended length from the building,
this could cause the ladder to slide out and it could damage the Ladder Lift.
Once the Ladder Lift has been erected correctly, the lifting hook can be lowered to attach a
load (see OPERATION: T
O
L
OWER A
L
OAD
). Then the Ladder Lift is operational.
6) Test the Ladder Lift as directed in MAINTENANCE: T

CHEDULE
.
WARNING: Winch brake may require a short break-in period to work properly.
Be sure to perform the Load Test (see MAINTENANCE: T
ESTING
S
CHEDULE
) before putting the
Ladder Lift into service. Do not attempt to raise or lower loads unless the brake on the hand
winch is functioning correctly, as described in the OPERATION section.
