4 SAFETY INSTRUCTIONS
4.1 Checking before assembly
Check whether the people assembling the stair tower are suitably qualified and check if the
location where the stair tower is to be erected is safe and suitable.
Note:
- The surface must be flat and sufficiently strong.
- The area must be free from obstructions, both at ground level and above the ground.
- Check whether the wind conditions are such that the stair tower may be used.
- Check whether all the components are present at the location.
- Damaged, incorrect or non-original components must not be used.
4.2 Assembly
The assembly of the stair tower is described in the assembly instructions. The stair tower
must be assembled by at least two people. Also use safety rails during the assembly. If
necessary, fit the rails temporarily.
The stair tower must be assembled on a flat surface. Check this using a spirit level. It is
possible to correct the stair tower by rotating the wheel spindles’ spindle nut. The wheels
must remain braked at all times, expect when the tower is being moved.
Make sure the wheels are locked, either by tightening the wing nut or by clipping the locking
nock over the edge of the strengthening ring.
The platforms must be secured by sliding the wind securing pin under the rung. The frames
must be locked together using the locking pin. The horizontals or railings must be fitted to
the stands in such a way that the claws’ openings face outwards.
The work platform must have: railings, intermediate railings and toeboards fitted all around.
4.3 Raising components
Components must be raised to higher levels by carrying them up the stairs.
Hoists must not be secured to the stair tower.

4.4 Outriggers/elbow outriggers
The outriggers/elbow outriggers stated in the assembly tables must always be fitted as
soon as the bottom section of the stair tower reaches a height of 2 metres.
The basic shape to be used, i.e. the outrigger/elbow outrigger to be used (small or
large), can be found in the assembly tables.
The basic shapes given below must be strictly followed!
If the required shape is deviated from, it may be necessary to use ballast. Contact the
manufacturer or supplier for further information. Small elbow outriggers may be
replaced by small outriggers and large elbow outriggers may be replaced by large
outriggers if, when using the outriggers, the same basic shape is maintained as for
the elbow outriggers. This means that the outriggers must be fitted in the same
position as the elbow outriggers when viewed from above.
Basic shapes
A: Small elbow outrigger, length 1300 mm B: Large elbow outrigger, length 2000 mm
1: Horizontal, length 2500 mm, art. nr. 9501.200.030

When the tower is positioned against a wall, do not remove the outriggers/elbow outriggers,
but turn them parallel to the wall.
When the tower is positioned in a corner, remove the inside outrigger/elbow outrigger, and
turn the outside two parallel to the wall.
