3 SOFT TOUCH PUSH KNOB LOCKING HINGE
HINGE OPERATION
For safety, follow these Soft Touch push knob hinge instructions:
The MT Series ladders inner section allows
the ladder to be folded into 3 set positions;
extension ladder, twin stepladder, and
storage. Each of these configurations is
made possible by using the Soft Touch
push knob locking hinge located on each
side of the ladder.
To adjust the angle of the ladder:
1)With the center hinges in the closed
position (See Figure 1) push the push
knobs with the palm of your hand
directly into the center of the ladder,
they will stay in the open position.
2)In the open position (See Figure 2)
the ladder angle can be adjusted.
Note: The open position can be verified
by the exposed triple inner posts on the
push knob (See Figure 2).
Figure 1

OPEN
Triple inner posts

3)When the ladder reaches any of the 3 set positions
the push knobs will automatically spring back into the
closed position.
4)To close ladder to the folded position repeat steps 1-3.
Note: Excess pressure on the center hinge will make the
push knob difficult to operate. Do Not Use any tools to pry or
manipulate the hinge and or the push knob. If the push knob
is difficult to use simply move one of the leg sections in or out
to unbind the lock.
• Serious injury or death could result if supporting hinges
are NOT LOCKED when ladder is in use.
• Make certain supporting hinges are LOCKED before
using ladder EACH TIME.
WARNING
4 SPRING LOADED “J” LOCKS
LOCK OPERATION
For safety, follow these Spring Loaded “J” Locks instructions:
The MT Series ladders outer sections allow the
ladder to telescope and change heights in all
the configurations, besides the scaffold mode.
Each of these configurations is made possible
using the 4 Spring Loaded “J” locks 2 each on
either side.
The Spring Loaded “J” locks are operated by
pulling straight out and then rotating them away
from the holes in the rails. Each “J” lock works
independently allowing the end user to work the
lock with one hand while holding the ladder with
the other.
To adjust the height of the ladder:
1)Unlock the 4 “J” locks by pulling out and
rotating the “J” lock away from the rung
hole (See Figure 3).
2)Raise the inner section to the desire height.
3)While holding the inner ladder section with
one hand, lock the 4 “J” locks by rotating
them into the locked position
(See Figure 4).
Figure 4
•Ensure all 4 “J” locks are secure in a rung hole before climbing.
•Maintain control of the inner section while raising or lowering,
failure to do so could result in injury.

5 PROPER USE
HOW TO SETUP POSITIONS
The Werner MT Series Telescoping Multiladder can be used in positions shown below with
no additional equipment required. The following instruction will demonstrate how to change
the Werner Telescoping Multiladder.
Position #1
Twin Stepladder
1) To configure the MT Series ladder into the
stepladder position, follow the directions for
changing the angle of the ladder (Section 3)
using the push knob locking hinge.
Note: The stepladder position is easiest
completed with the ladder standing up. In this
position excess pressure is not exerted on
the hinge.
2) At this point the height of the ladder can be
changed to the desired height using the Spring
Loaded “J” locks and the instructions for them
(Section 4).
1) To configure the MT Series ladder into
the Stairway Stepladder position – this
position is used when the user needs to
work in a stairway.
2) To achieve this position, configure the
ladder in the stepladder configuration
as described in position #1. Raise to
desired height.
3) Lower one side of the inner section until
the desired step height is reached as
described in position #2 above.
4) Position ladder on stairway, ensuring all
legs are on firm ground or steps.
Stairway Stepladder
• For every position all hinges are supporting hinges and must be locked.
• Never straddle front and rear sections.
• Always face ladder and maintain firm grip while on it.
• DO NOT stand on or above second rung from top of ladder.
CAUTION
• Always face ladder and maintain firm grip while on it.
• DO NOT stand on or above the second rung from top of ladder.
CAUTION
Position #2

1110
1) Configuring the MT Series ladder into the
extension ladder position, as with the stepladder
position, the extension ladder position starts with
changing the angle.
Note: The push knob hinge will catch in each of
the 3 positions. Continue to disengage and rotate
the sections until the desired position is reached.
2) With the ladder standing up, unlock the upper
section “J” locks and walk the upper ladder
section out. If more height is needed, extend the
opposite section in the same way. Slide outer
sections apart until desired length is met.
75° Approximately
1) Configuring the MT Series ladder into the 2-Scaffold
Base position requires the use of the dynamic hinge
kit that is included with your MT Series ladder.
2) Separate the inner and outer sections completely by
unlocking the “J” locks and sliding the outer sections
off the inner section.
3) Place inner section in stepladder position.
4) Place dynamic hinge into outer section rail
by threading narrow tab (See Figure 5) of
dynamic hinge into inside of the rail with the wider
tab on the outside of the rail (See Figure 6).
5) Lock using “J” locks as shown in Figure 6.
Repeat on other side.
6) Ensure rungs face out opposite the hinge hook
direction (See Figure 7). Spread outer sections
apart as shown in Figure 8.
7) To close ladder, bring outer sections together.
Unlock “J” locks and remove dynamic hinges.
