Figure 4 Fixing the machine
3.9 Setting step height
The machine is in danger of falling if the travelling supports (23) and safety
supports (24) are not adjusted properly to the step height of the escalator to
be cleaned.

Move machine to the first completely extended step.

Fix the machine in the middle of the escalator.

Pull the star handle (47) down. Then lower the machine. The machine has to stand
on the rear legs now. So the gliding rails (25) do not touch the escalator completely.

Open the attachement screw and check if the travelling support (23) and the safety
support (24) touch the escalator.

Move the star handle (47) to a higher position (move it a bit more to the top than the
highest distance between the escalator and the gliding rail (25)).

Lift the machine (6) and lower (11) it. Now the whole gliding rail (25) have to touch the
escalator. If not then please move the star handle (47) more to the top and repeat the
process.

Thighten the attachement screws again and make sure that the travelling support (23)
and the safety support (24) touch the escalator.
Make sure that the machine is resting uniformly on the two travelling strips and
all four supports and that the wheels are approx.. 3-4 mm distant from the
step!
If this is not the case, the adjustment procedure must be repeated!
Incorrectly adjusted travelling supports (23) will mean that the operator will
have to use more force! In addition the travelling supports (23) brake earlier.
