One times fold telescopic ladder Multi times fold telescopic ladder  

Introduction

The telescopic ladder, by it is unique construction, extends from a compact format (illustration ①) to, either full length (illustration ②), or any intermediate length (illustration ③).
The telescopic ladder must be handled, cared for and maintained in accordance with the following instructions.
1. Locking mechanism
The telescopic ladder locks at every step with two steel locking pins that automatically spring into place when the ladder is opened (extended).
Each locking pin is connected to locking lever (illustration ④), that has two functions;
(1) to indicate that an opened ladder is securely locked, both locking levers under each step drop DOWN at an angle of approx 60 degrees, in relation to the step (illustration ⑤)
(2) when closing the ladder, the locking levers will release the locking mechanism automatically, as each section is lowered.
2.Opening the ladder
Full length
To open the telescopic ladder to its full length, proceed as follows;
(1) The ladder is opened to its full length by placing it on a firm level surface. During opening, stabilize the ladder with one foot placed on the lower step (illustration ⑥).
(2) Open the ladder from the top by gripping the top step with both hands. Extend the top section full, then extend the next section fully. At the same time check that both locking levers (illustration -A- ⑦) drop DOWN at an angle of 60 degrees in relation to the step (illustration ⑤).
(3) Continue opening section by section, until the ladder is opened to its full length (illustration ②).
(4) Please Note that the 2nd step from the bottom has locking levers with pull rings. These work in reverse to the other levers (illustration ⑧). The indicate that the section is locked when locking levers are in an UPWARD position and fully inserted in the step. Only the pull rings can be seen under the step.

NOTE! Check carefully that the locking levers with pull rings are in a locked position.

Intermediate length
To open the telescopic ladder to any intermediate length, proceed as follows:
(1) The ladder is opened to any intermediate length, by placing it on a firm level surface. During opening, stabilize the ladder with one foot placed on the lower step (illustration ⑥).
(2) Open the ladder by extending the bottom section using both hands, grip the third step (counted from the bottom) and extend this section fully by pulling upwards (illustration ⑨).
(3) Thereafter, continue with on section at a time, until the ladder is exlended to the desired length.
(4)Check that both locking levers on each step drop DOWN at an angle of approx 60 degrees, in relation to the step at each section (illustration ⑤).

NOTE! To insure that the highest fully opened section is properly locked, extend the next higher section another 15 cm, until the locking levers drop DOWN at an angle of 60 degrees (illustration⑩-B-respectively-A-) Notice that the 2nd step from the bottom have locking levers with pull rings. These work in reverse to the other levers (illustration ⑧). They indicate that the section is locked when the locking levers are in an UPWARD position and fully inserted in step. Only the pull rings can be seen under the step. Check carefully that the locking levers with pull rings are in a locked position.

3.Closing the ladder
To close the ladder, proceed as follows:
(1) Hold the ladder in an upright position. With one hand gripped firmly on one of the vertical tubes (illustration ⑾).
(2) With the other hand, pull down the pull rings (illustration ⑾), one at a time, until the locking mechanism is released and the ladder can be closed by slowly sliding down section by section. (Sometimes you need to pull the first ring a second time).
(3) When the locking mechanism is release, balance the ladder with a firm grip using both hands to grip the tubes. At the same time carefully and slowly close the ladder by sliding down section by section (illustration ⑿).

NOTE! To avoid the risk of getting your hands trapped, do not put them on or between the steps while closing the ladder.

4.Shortcning the opened ladder
When shortening an already opened ladder, always close the ladder first (see “Closing the Ladder”), and thereafter open the ladder to the desired length (see “Opening the Ladder, intermediate length”).

5.Cautions&Warnings
For safety reasons ladders in general shall be used with care and common sense.
With regard to the telescopic ladder,we also want to point out the following:
(1) The ladder is used at an angle of 75 degrees,in relation to the ground(illustration13)
(2) The ladder is built for a maximum load of 150kg(illustration14)
(3)The ladder must be used on a flat firm level surface.
(4)The upper rung must not be used as a foot step.
(5)The ladder must be used with a regular distance between the steps(illustration15)
(6)Avoid using the ladder in locations such as water-filled wells, as this may result in a multi-function due to dirt and water getting into the tubes.
(7)Avoid subjecting the ladder to knocks or rough treatment, as damage to the tubes directly affects the telescopic function.
(8)Always transport in the folded position, so that the telescopic tubes are protected inside each otherand cannot be damaged.
(9)The ladder must not be used hanging from the top rung.
(10)Do not open, close or use the ladder upside down.
(11)The ladder must not be used in a horizontal position, such as resting on a step or saw horse. In an emergency situation, the ladder can be used as a stretcher if extend to a maximum length of approx.2m
