The vibration value is lower and does not exceed 2.5 m/s².
Values determined using the procedure described in the standard EN 12649.
The measurements are made with new machines. Actual values may vary with site conditions,
in terms of:
Materials worked
Wear Machine
Lack of maintenance
Inappropriate tool for application
Tool in poor condition
Unskilled operator
Etc…
The exposure time to vibration is based on the performance of work (related to the adequacy
Machine / Tool / worked material / operator)
When evaluating risks due to hand-arm vibration, you need to take into account effective usage
at rated power of machine during a full day of work; quite often you will realise that effective
utilisation time represents around 50% of overall duration of work. You have to consider, of
course, breaks, water feeding, preparation of work, time to move the machine, disk mounting…

5 OPERATING THE MACHINE
5.1 Site of work
Remove from the site anything, which might hinder the working procedure!
Make sure the site is sufficiently well lit!
Make sure you have a continual adequate view of the working area so you can intervene in the
working process at any time!
Keep other staff out of the area, so you can work securely.
5.2 Preparing the site
Prepare the concrete as for manual trowelling. Assure a well levelled surface (we recommend the
use of a beam or better a vibrating screeder). When slab has set sufficiently firm so that the
operator can walk on it, leaving only a slight impression (approx.3mm), it is ready for the floating
operation.
5.3 Floating and finishing operation
To use the machine correctly, you must face it with the two hands on the handle.
Handling the machine
Operate the machine from right to left as shown in the following drawing:
To move the machine:
Forward (I on the following drawing), turn the handle clockwise.
Backward (II), turn the handle counterclockwise.
To the left (III), pull up the handle.
To the right (IV), push down the handle.

VERS.2015.04.27 CT 901 MP_MAN_EN
16
Tilting the blades
Floating the slab is done with the blades nearly flat on the surface of the concrete; however it is
recommended that the blades are just slightly tilted to avoid the suction and drag created in normal
operation of float blades on wet concrete. For the finishing operation, tilt the blades. Start with a
small pitch of 4 to 6 mm. After each finishing pass, continue to tilt blades.
Depression or high spot
To fill a depression or cut down a high spot, simply move the machine back and forward over the
area until the desired surface is obtained.
IMPORTANT: Do not allow the machine to stand in one spot on wet concrete –remove the
machine from the slab when it is not used.
CAUTION: when the machine is switched off, the tools will continue turning slowly to complete stop.
Be therefore very careful to avoid injuries.
