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.

Maintenance of the machine
Always perform the maintenance of the machine with the machine isolated from the electrical
supply and with tools idle.
Lubrication
The CT901ME uses life-lubricated bearings. Therefore, you don’t need to lubricate the machine at
all.
Control and change of the belt
To control the tension of belts, open the belt guard, and push on the belts. You should be able to
gape the belt as thick as a finger. If the tension is incorrect, loosen the nuts securing the motor on
the machine and move the motor until the correct tension is reached. Make sure that the pulleys are
aligned correctly. Then retighten the nuts.
