Checking the container level monitoring system
The product has fill level monitoring that prevents water from making its way into the turbine, thus preventing damage to the turbine and the
product. The fill level is monitored by 2 wire sensors.
Make sure that the wire sensors are always in perfect working order and that no modifications have been made and nothing has been tampered
with. Otherwise, product functionality is not ensured. Check and clean the sensors only as described below.
1. Remove the suction head from the waste material container.
2. Check the cut-off contacts (wire sensors) for dirt accretions and if necessary, brush the contacts clean.
3. Check the seal at the suction head and clean it with a cloth if necessary.
4. Position the suction head on the waste material container.
Transport
Do not attempt to crane-lift the vacuum cleaner.
▶
Store accessories and attachments in the holders intended for the purpose.
▶
Empty the vacuum cleaner before the vacuum cleaner is to be carried to another location.
▶
After using it to vacuum up liquids, do not tilt the vacuum cleaner and transport the vacuum cleaner in the upright position only.
▶
Use the tapered adapter to connect both ends of the hose together conveniently for transport.
WARNING
Risk of injury by dusts that are hazardous to health! Hazardous material that has been vacuumed up can escape through the suction hose
intake fitting.
▶
Close the hose inlet socket with the cap before transporting the vacuum cleaner and when it is not in use.
Safety instructions for dust-free transportation
The following measures must be implemented for dust-free transportation:
In principle, all parts of the vacuum cleaner must be considered contaminated if the vacuum cleaner was used in a contaminated area. Treat
the vacuum cleaner accordingly and take all necessary measures to prevent dispersion of the hazardous dust.
▶
Place the suction hose in the transport bag provided for the purpose and seal the transport bag.
▶
Seal the suction intake.
▶
Remove the suction tube with floor nozzle from the holder. Carry the vacuum cleaner by the carrying handle and the suction tube, not the
pushbar.
▶
Before you remove the vacuum cleaner from a contaminated area, the outside of the vacuum cleaner must be decontaminated by vacuum
and thoroughly cleaned or treated with sealants.
Storage
▶
Clean the vacuum cleaner after vacuuming up dry dusts
▶
Make sure that no residual water remains in the container and that there are no residues for example of drilling slurry that can become caked
in the suction hose and container.
▶
Store the vacuum cleaner in a secure, dry place where it is inaccessible to unauthorized users.
▶
The vacuum cleaner may be stored only indoors.
