The joints of the ladder are reliable mechanisms, consisting of several moving parts connected to
the side rail in such a way that they can’t be disassembled. Therefore, it is necessary to keep the
joints clean (removing sand, concrete, and mortar). Lubricate all joints with oil before and after
the season, and store the ladder in a dry place.
In case of using the ladder as a platform (Fig. 1, position 3), it is necessary to mount the platform
(available as accessories). Place both parts of the platform (A, B) on the straight segment of the
ladder, and press it against the rungs in such a way as to prevent its motion (Fig. 4). To do this,
there are offsets on the bottom side of both platform parts. Adjacent ends of platform parts must
meet above the rung, see the detail in Fig. 4.
ATTENTION: Maximum load of the ladder in the “platform” position is 120 kg.

3.2 Three-piece universal ladder. Models JC-307A, JC-310A, JC-313A.
Three-piece universal ladder is supplied without a mounted stabilization crossbar. it consists of a
dismountable set of three ladders with straps, stabilization crossbar, and connecting accessories to
mount the stabilization crossbar. Upon mounting the stabilization crossbar, the ladder can be used
in several versions, allowing for the narrow part to be used as a separate supporting ladder (except
for model JC-313A). The ladder can be used as supporting ladder, extensible ladder, or step-ladder
without support, or step-ladder without support with extensible ladder (Fig. 7).
The process for working with this type of ladder:
a) Remove the packaging.
