Troubleshooting - COMAC CA30 Betriebsanleitung

ATTENTION! The vacuum cleaner is furnished with a system which interrupts the
suction when the tank has reached its maximum capacity. When this occurs,empty the
tank, following the instructions in this booklet.
ATTENTION! for particular thick liquids suction (chemical water with shavings,
mud, leaves) use the special nylon filter (optional).
CLEANING AND MAINTENANCE OF THE VACUUM CLEANER:
Disconnect the plug from the source of electricity (figure 26), unhook the tank latches
(figure 27) and remove the head and the dust filter from the tank (figure 28). Bend the
vacuum cleaner until the handle touches the floor and empty the contents of the tank
into another container (figure 29). Then put the tank back into its original position
(figure 30) and if necessary (for dry vacuum cleaning only) insert the dust filter (figure
3), place the head in its correct position and secure it onto the tank with the latches
(figure 31) and start cleaning again.
ATTENTION! Before performing any cleaning and maintenance on the vacuum
cleaner, always disconnect the plug from the source of electricity.
Make sure that the cable is not cut or damaged (if it is, apply to the nearest authorized
service centre for replacement).
a) Clean the tank, do not let it stand for a long time with dust or dirty water.
b) Clean the cloth filter frequently.
c) Always use only original replacement parts and attachments.

b) Check if the switch is in the on position.
c) The tank may be filled with liquid. lf it is, empty the tank, following the
