Frequently Asked Questions - CA 340 NILFISK

How to start the CA 340 machine?

Plug in the machine, set the main switch to ON, then activate the suction and water supply switches. Press the pedal to lower the brush and squeegee.

How to adjust the brush pressure?

Turn the adjustment screw to the right to increase pressure, to the left to decrease.

Why is the suction weak?

Check the condition of the squeegees, suction opening, hose, cover gasket, float valve, and suction filter. Clean or replace faulty parts.

What to do if the brush does not rotate?

Check the drive belt and ensure the brush is properly attached.

How to maintain the machine after each use?

Empty and rinse the solution and recovery tanks, clean the brush, squeegees, and filters. Store the machine in a clean, dry place.

What type of cleaning product to use?

Use only liquid, non-flammable, low-foaming products designed for floor scrubbers. Follow the manufacturer's mixing instructions.

What does the indicator light or float that blocks suction mean?

The float prevents solution from entering the suction system. When it closes, the machine stops suctioning: empty the recovery tank.

How to replace the squeegee blades?

Unplug the machine, remove the tanks, tilt the machine to the stop position, unscrew the two screws of the squeegee, remove it, and replace the blades.

What accessories are available for the CA 340?

FILLING THE SOLUTION TANK

1. Fill the solution tank with cleaning solution.
2. Do not fill up the solution tank completely: leave 3 cm from the top of the tank.
3. The solution should be a mixture of water and a cleaning chemical according to the type of job.
4. Always follow the dilution instructions on the chemical container label.
5. The temperature of the cleaning solution must not exceed 40^ .

CAUTION!

Use only low-foaming, non-flammable liquid detergents intended for machine application.
