ASSEMBLY INSTRUCTIONS
SYSTEM TOWERS OVER EXTRACTABLE BASE
Having checked that all of the requirements, proceed with the assembly of the base section:
•Join the two wheel-bearing sections with the two base connecting braces using the four handgrip
screws supplied;
• Before tightening the screws fully, position the first two lateral frames; taking care to position the
pawls towards the inside and the labels towards the outside.
• Tighten the screws, engage the brakes in the four wheels and proceed to the horizontal extraction of
the adjustable feet to the maximum length the surrounding surface space allows; Pull the extractables
up to the MAX line Then tighten the extraction locking screw.
• Level the base section using the screws on the feet, taking care to raise all the wheels at least 20 mm
off the ground; once levelled, tighten the lock nuts;
• Continue the assembly by inserting the 2 connecting braces into the slots on top of the uprights of the
lateral frames; taking care to position the pawls towards the inside and the labels towards the outside.
• Install the diagonal bracing rods, hooking the ends onto the anti-slip latches on the connecting braces;
• Position the mobile access tower’s elements on the fourth rung from the bottom of the first two lateral
frames;
• First, position the 2 long toeboards parallel to the walking surface. Now fit the 2 short toeboards into
the respective housings found in the long boards;
• At this point at least one of the workers authorised to assemble the tower must put on a safety belt
and climb onto the work platform from the inside of the tower through the trapdoor;
• After having securely attached the end of the rope of the safety belt to one of the two already fitted
connecting braces, the next two lateral frames can be attached and the tower can then continue to be
assembled following the same sequence of operations described up to this point;
• If the tower must be erected to a work platform height above m 2,50 the 4 stabilizers must be fitted
at this point
• arrange the stabilizers in open position remove the respective stabilizers couplers from the bag
supplied. Open the rear clamp of the first coupler by loosening the eyebolt nut. Fit the coupler to
the tower’s upright on the rung weld point at the height that allows accomodating the upper vertical
portion of the stabilizer. Repeat the operation on the same upright with a second coupler. Place the
coupler at an appropriate distance from the first in order to accommodate the same stabilizer. Open
the front clamps of the two couplers by loosening the respective eyebolt nuts. Position the stabilizer
between the two couplers at an angle of about 120° in relation to the tower’s longer side.
