 Make sure the retaining hook [15] on top of the frame is preventing the telescopic sections
[8][9] to move. Put your right hand on top of the vertical frame [7] and pull the assembly [10]
towards you while holding the brake lever.
 Rotate the lock [12] at the end of the slide bar [11] as far as possible clockwise when the winch
assembly is fully extended to secure the winch assembly position. Always check whether the
lock is engaged before lifting a load.
 Pull the retaining hook [15] away to allow the telescopic sections [8][9] to move freely.
Cradle assembly
 Attach the load cradle [20] on top of the vertical frame [7] by inserting the pin of the cradle
head [23] into the hole of the inner telescopic section [8]. Make sure that the tilt latch is
hooked over the protrusion to avoid accidental tilting of the cradle.
 Attach the crossbars [24] to the cradle [20] by sliding the tapered plates of the crossbars into
the tapered sockets of the cradle until the flat spring on the bottom of the crossbar snaps in
place. The two crossbars are identical.
 Slide the extendable arms [21] in the cradle, with the holes facing the pin locks [22] (see figure
4).

7. Operation
 First verify that the lift is not damaged (especially the cable) and that the brake drum [17] is
clean and dry. Make sure the lift is at room temperature.
 Lock the casters [3] of the lift and lower the backstop [6].
 Lower the cradle [20] by turning the winch wheel [16].
 Release the tilt latch and tilt the cradle [20].
 Position the hooks [25] to support the panel. Turn the cradle so the hooks are facing away from
the winch wheel [16].
 Extend the arms [21] as far as necessary to support the whole panel. The arms can be extended
in 3 positions. For safety reasons, the pin of the pin lock must always be secured in one of the
holes of the extendable arm. Do not use the lift when the pin locks are not secured.
 Place a panel on the hooks [25], finish side facing the crossbars [24]. Gently lower the panel
onto the crossbars and extension arms.
 For ceiling mounting, tilt the cradle horizontally and hook the tilt latch over the protrusion to
secure it. Note that there is still about 10° side-to-side slack. For sloped panel mounting, leave
the cradle unlatched.
 Unlock the casters [3] and raise the backstop [6]. Carefully roll the lift to where the panel needs
to be installed.
 For sloped or wall panel mounting, always lower the backstop [6] before lifting the panel.
 Turn the winch wheel [16] until the panel is at the desired height. Always check for overhead
obstructions when lifting a panel. Note that the brake is spring-operated, preventing the panel
from automatically lowering when releasing the winch wheel.
 To lower the panel, hold the winch wheel [16] and slowly release the brake handle [18].
 Make sure the panel is sufficiently attached to the wall or ceiling before removing the
hoist.
