INTRODUCTION
The telescopic ladder by its unique construction ex-
tends from a compact format (Fig. 1) to either full length
(Fig. 3) or any intermediate length (Fig.2).
The telescopic ladder must be handled with care and
maintained in accordance with the following instruc-
tions.
LOCKING MECHANISM
The telescopic ladder locks every single step with two
steel locking pins. The locks snap automatically in
when the ladder is either opened or extended.
Each locking pin is connected to a locking lever (Fig. 4)
that has two functions:
1. To indicate that an opened/extended ladder is
securely locked (when both pins are touching the
ladder rails).
2. To release the locking mechanism automatically,
as each section is lowered while closing the la-
dder. When the locking mechanism is unlocked,
there will be a distance between the pins and the
joints.
OPENING THE LADDER
Full length
To open the telescopic ladder to its full length, user
must follow this procedure:
1. Place the ladder on a firm and level surface.
2. Open the ladder from the top by gripping the top
step with both hands. During this process, stabi-
lize the ladder with one foot placed on the lower
step (Fig. 7).
3. Extend the top section fully and assure that both
locking pins are properly locked.
4. Repeat this process for each section until reaching
full extension (Fig. 2).
NOTE: Always check the ladder is stabilized and
properly locked before climbing.
Intermediate length
To open the telescopic ladder to any intermediate leng-
th, user must follow this procedure:
1. Place the ladder on a firm and level surface.
2. Open the ladder by extending the bottom section
using both hands.
3. Grip the third step (counted from the bottom) and
extend this section by pulling upwards (Fig. 8).
4. Once extended, assure both pins are properly loc-
ked (Fig. 5).
5. Repeat this process until the ladder is extended to
the desired length.
NOTE: Always check the ladder is stabilized and
properly locked before climbing.
